Description

本発明は、すぐれた吸音性を有するポリプロピレン樹脂組成物に関する。より詳しくは、本発明は、基礎樹脂としてのポリプロピレン樹脂と、吸音成分としてのタルクおよび硫酸バリウムの混合物と、ナノ・クレー（ナノメートル・サイズのクレー）とよりなるポリプロピレン樹脂であって、排水排出管に用いるの適したものに関する。本発明のポリプロピレン樹脂は、ポリプロピレン樹脂に固有のすぐれた耐衝撃性および耐熱性を維持しながら、改善された吸音性を示す。   The present invention relates to a polypropylene resin composition having excellent sound absorption. More specifically, the present invention is a polypropylene resin comprising a polypropylene resin as a base resin, a mixture of talc and barium sulfate as a sound-absorbing component, and nano clay (nanometer sized clay). It relates to suitable for use in tubes. The polypropylene resin of the present invention exhibits improved sound absorption while maintaining the excellent impact resistance and heat resistance inherent in polypropylene resin.

ポリプロピレン樹脂は、加工しやすく、化学的抵抗力が強く、耐風雨性があり、折り畳み自在である等々のすぐれた性質のため、家庭用電気器具、建設材料、内装材料、例えば自動車部品や電気部品等の各種用途で広く使用されている。ポリプロピレン樹脂は、一般に、射出成形物、フィルム、あるいは吹き込み成形物の形で使用される。近年、火炎抑制性、耐熱性、剛性、耐衝撃性、および長期耐風雨性を示す複合機能を有する新しいグレードのポリプロピレン樹脂として、それらを新規な用途、とくに建設および産業用材料としての用途に使用するための数多くの試みがなされている。最近は、生活環境の多様化のため、住居の環境を快適で贅沢なものにしたいという傾向が強くなっている。とくに、戸建住宅やマンションでも、低公害および低騒音などの環境要因ならびに便利さを含む複合機能に注目が集まっている。環境の観点から、人々は、きれいな空気、深い森、低騒音に囲まれた自然でやさしい場所に住むことを欲するようになっている。   Polypropylene resin is easy to process, strong in chemical resistance, weather resistant, foldable, etc., so it has excellent properties such as household appliances, construction materials, interior materials such as automobile parts and electrical parts. It is widely used in various applications such as. Polypropylene resins are generally used in the form of injection molded articles, films or blow molded articles. In recent years, as a new grade of polypropylene resin with a composite function showing flame suppression, heat resistance, rigidity, impact resistance, and long-term rain resistance, they are used for new applications, especially for construction and industrial materials Many attempts have been made to do this. Recently, due to the diversification of living environment, there is a strong tendency to make the living environment comfortable and luxurious. In particular, even in detached houses and condominiums, attention has been focused on complex functions including environmental factors such as low pollution and low noise, and convenience. From an environmental point of view, people want to live in a natural and friendly place surrounded by clean air, deep forests and low noise.

マンションなどでの異なる階への騒音の伝達は、住人の間のトラブルの原因になる。このような騒音は、主として、床を区切るコンクリートの厚さ、また、浴室に敷設されているパイプのような廃水排出管、水切り台、トイレ、立ち上がり管、地下の横管などの厚さが薄いことによって生じるものである。   Noise transmission to different floors in condominiums and the like causes troubles among residents. Such noise is mainly due to the thickness of the concrete that separates the floor, and the thickness of wastewater discharge pipes such as pipes laid in the bathroom, drainers, toilets, rising pipes, underground horizontal pipes, etc. It is caused by that.

ポリ塩化ビニル（ＰＶＣ）管は、マンション建設の廃水排出管として、硬質の排水管に広く使用されているが、これらは、大きくいって、二種類すなわちＶＧ１型とＶＧ２型に分類される。これら二種類のＰＶＣ管は、いくつかの点で互いに異なるものであり、それらが、価格の決定要因になっている。ＶＧ１型のＰＶＣ管は、厚さが大きく、重く、高価であり、廃水排出管としては、ＶＧ２型のＰＶＣ管が圧倒的に多く使用されている。   Polyvinyl chloride (PVC) pipes are widely used as hard drain pipes as wastewater discharge pipes for condominium construction, but they are broadly classified into two types, namely, VG1 type and VG2 type. These two types of PVC pipes are different from each other in several respects, which are the determinants of price. The VG1 type PVC pipe is thick, heavy and expensive, and the VG2 type PVC pipe is overwhelmingly used as a waste water discharge pipe.

ＰＶＣ樹脂は、建設用の管材料として広く使用されているが、吸音効果や防音効果が十分でない、物理的性質が劣っているなど、多くの欠点をもっている。具体的には、ＰＶＣ樹脂は、耐熱性の観点からは、約７０℃のビカー軟化点を示すこと、および、アイゾット衝撃強度（室温、ノッチ）が、２．５ｋｇ・ｃｍ／ｃｍであり、剛性の観点からは、曲げ弾性係数（ｋｇ／ｃｍ２）が約２８０００であることが知られている。 PVC resin is widely used as a pipe material for construction, but has many drawbacks such as insufficient sound absorption effect and soundproofing effect, and poor physical properties. Specifically, from the viewpoint of heat resistance, the PVC resin exhibits a Vicat softening point of about 70 ° C., and the Izod impact strength (room temperature, notch) is 2.5 kg · cm / cm, and rigidity From this point of view, it is known that the flexural modulus (kg / cm 2 ) is about 28000.

ＰＶＣ樹脂のこれらの問題を解決するため、例えば、吸音材料および防音材料としてグラスファイバーを添加すること、スピン構造または３層壁構造のＰＶＣ管（下記特許文献１及び特許文献２）を導入することなど、いくつかの提言もなされている。しかし、建設コストの上昇にもかかわらず、騒音遮断効果、耐熱性、および耐衝撃性の改善は、まだ不十分である。他方、鋳鉄製の管は、架設が困難なこと、耐久性に劣ること、価格が高いことなどの欠点がある。
特開平５−２７２６９１号公報 特開平６−１７４１７５号公報 In order to solve these problems of the PVC resin, for example, glass fiber is added as a sound absorbing material and a soundproofing material, and a PVC tube having a spin structure or a three-layer wall structure (Patent Document 1 and Patent Document 2 below) is introduced. Some suggestions have been made. However, despite the increase in construction costs, improvements in noise isolation, heat resistance, and impact resistance are still insufficient. On the other hand, cast iron pipes have drawbacks such as difficulty in erection, inferior durability, and high price.

下記特許文献３は、ポリプロピレン・コポリマーに無機充填剤として硫酸バリウムを５０〜７５％添加することを記載している。しかし、この組成物は、該無機充填剤の吸湿性が高いために管に成形するのが困難であり、また無機充填剤が多量に存在するために比重が極めて高くなる。さらに、多量の無機充填剤の存在にもかかわらず、組成物の衝撃強度は低く、耐熱性が悪く、また硬度も低い。したがって、この組成物から製造された管は、比較的容易に変形し、また高価であるという欠点をもっている。
韓国特許第１９９９−０００１８８号公報 The following Patent Document 3 describes that 50 to 75% of barium sulfate is added as an inorganic filler to a polypropylene copolymer. However, this composition is difficult to be formed into a tube due to the high hygroscopicity of the inorganic filler, and has a very high specific gravity due to the presence of a large amount of the inorganic filler. Furthermore, despite the presence of a large amount of inorganic filler, the impact strength of the composition is low, heat resistance is poor, and hardness is low. Thus, tubes made from this composition have the disadvantages of being relatively easily deformed and expensive.
Korean Patent No. 1999-000188

ポリオレフィン樹脂の機械的性質および耐熱性の劣化は、無機充填剤が、機械的手段で単に樹脂の中に組み込まれていることによるものである。   The degradation of the mechanical properties and heat resistance of the polyolefin resin is due to the inorganic filler being simply incorporated into the resin by mechanical means.

したがって、すぐれた吸音性、耐衝撃性、および耐熱性を示し、しかも、従来のＰＶＣ管の騒音問題を解決しまた従来の鋳鉄製の管の価格より低い管成形材料に対するニーズは、依然として存在する。また、環境にやさしくリサイクルが容易な管成形材料に対するニーズも存在する。   Accordingly, there remains a need for tube forming materials that exhibit excellent sound absorption, impact resistance, and heat resistance, yet solve the noise problems of conventional PVC pipes and are lower than the price of conventional cast iron pipes. . There is also a need for tube molding materials that are environmentally friendly and easy to recycle.

したがって、本発明は、上に挙げた問題を考慮してなされたもので、耐衝撃性、耐熱性、吸音性の高い管用のポリプロピレン樹脂組成物であって、ポリプロピレン樹脂と、二つの吸音性成分の適当な混合比の混合物と、ナノ・クレーＭ／Ｂとよりなるポリプロピレン樹脂組成物を提供することをその特徴とするものである。   Accordingly, the present invention has been made in consideration of the above-mentioned problems, and is a polypropylene resin composition for pipes having high impact resistance, heat resistance, and sound absorption, which is composed of polypropylene resin and two sound absorption components. The present invention is characterized by providing a polypropylene resin composition comprising a mixture having an appropriate mixing ratio and nano clay M / B.

層状のクレー物質などの無機物質を含むポリプロピレン樹脂組成物は、マスター・バッチとして形成されるため、機械的手段を用いる単純な混合法で製造されたものと比較して、非常に良い特性を示す。   Polypropylene resin compositions containing inorganic materials such as layered clay materials are formed as master batches and therefore exhibit very good properties compared to those produced by simple mixing methods using mechanical means. .

本発明の特徴にもとづけば、ポリプロピレン樹脂組成物において、（Ａ）ポリプロピレン樹脂５５〜７０重量％、（Ｂ）タルクおよび硫酸バリウムの混合物であって、タルクと硫酸バリウムとの混合重量比が１：９〜９：１の範囲であるタルクと硫酸バリウムとの混合物１５〜５０重量％と、（Ｃ）ナノ・クレー０．０１〜１５重量％と、よりなるポリプロピレン樹脂組成物が提供される。
必要ならば、本発明にもとづくポリプロピレン樹脂組成物は、さらに、（Ｄ）相溶化剤０．０１〜５重量％よりなる。 According to the characteristics of the present invention, in the polypropylene resin composition, (A) a polypropylene resin 55 to 70% by weight, (B) a mixture of talc and barium sulfate, wherein the mixing weight ratio of talc and barium sulfate is Provided is a polypropylene resin composition comprising 15 to 50% by weight of a mixture of talc and barium sulfate in the range of 1: 9 to 9: 1 and (C) 0.01 to 15% by weight of nano clay .
If necessary, the polypropylene resin composition according to the present invention further comprises (D) 0.01 to 5% by weight of a compatibilizing agent.

以下、本発明にもとづくポリプロピレン樹脂組成物を、それぞれに構成成分にもとづいてより詳細に説明する。
本発明の組成物に含まれるポリプロピレン樹脂（Ａ）は、シンジオタクチック・ホモポリプロピレン、アイソタクチック・ホモポリプロピレン、プロピレン−エチレン・ブロック・コポリマー、およびプロピレン−エチレン・ランダム・コポリマーを含むものである。プロピレン−エチレン・ブロック・コポリマーおよびプロピレン−エチレン・ランダム・コポリマーが好ましい。アイソタクチック・ホモポリプロピレンの中では、１３Ｃ−ＮＭＲ（核磁気共鳴）スペクトルによって識別されたアイソタクチック五価留分０．８０〜０．９９、好ましくは０．９０〜０．９９、を有する結晶性ポリプロピレンを使用することが好ましい。プロピレン−エチレン・ランダム・コポリマーの中では、機械的性質および押し出し処理性を考慮して、室温で２〜１０ｋｇ・ｃｍ／ｃｍのアイゾット衝撃強度を有するランダム・コポリマーを使用することが好ましい。プロピレン−エチレン・ブロック・コポリマーの中では、機械的性質、押し出し処理性、成形性、衝撃抵抗、等々を考慮して、室温で１１ｋｇ・ｃｍ／ｃｍ以上、より好ましくは５０ｋｇ・ｃｍ／ｃｍ以上のアイゾット衝撃強度を有するインパクト・コポリマーを使用することが好ましい。本発明にもとづいて使用されるポリプロピレン樹脂は、樹脂の種類の如何にかかわらず、メルト・インデックス（ＡＳＴＭ Ｄ１２３８：２３０℃、負荷２．１６ｋｇ）０．１〜６０ｇ／１０分を示さなければならない。ポリプロピレン樹脂のメルト・インデックスが０．１ｇ／１０分未満であると、樹脂組成の射出成形性が十分でなく、フロー・マークなどの外観上の欠陥が生じる。他方、ポリプロピレン樹脂のメルト・インデックスが６０ｇ／１０分を超えると、樹脂組成の射出成形性はすぐれたものとなるが、押し出し成形性が十分でなく、また耐衝撃性が著しく低下する。 Hereinafter, the polypropylene resin composition based on this invention is demonstrated in detail based on each component.
The polypropylene resin (A) contained in the composition of the present invention contains syndiotactic homopolypropylene, isotactic homopolypropylene, propylene-ethylene block copolymer, and propylene-ethylene random copolymer. Propylene-ethylene block copolymers and propylene-ethylene random copolymers are preferred. Among isotactic homopolypropylenes, isotactic pentavalent fraction identified by 13 C-NMR (nuclear magnetic resonance) spectrum is 0.80 to 0.99, preferably 0.90 to 0.99. It is preferable to use crystalline polypropylene having the same. Among the propylene-ethylene random copolymers, it is preferable to use a random copolymer having an Izod impact strength of 2 to 10 kg · cm / cm at room temperature in consideration of mechanical properties and extrusion processability. Among propylene-ethylene block copolymers, in view of mechanical properties, extrusion processability, moldability, impact resistance, etc., 11 kg · cm / cm or more, more preferably 50 kg · cm / cm or more at room temperature. It is preferred to use an impact copolymer having Izod impact strength. The polypropylene resin used in accordance with the present invention must exhibit a melt index (ASTM D1238: 230 ° C., load 2.16 kg) 0.1-60 g / 10 min, regardless of the type of resin. When the melt index of the polypropylene resin is less than 0.1 g / 10 minutes, the resin composition has insufficient injection moldability, resulting in appearance defects such as flow marks. On the other hand, when the melt index of the polypropylene resin exceeds 60 g / 10 minutes, the injection moldability of the resin composition is excellent, but the extrusion moldability is not sufficient, and the impact resistance is remarkably lowered.

本発明の樹脂組成物中の成分（Ａ）の含有量は、５５〜７０重量％の範囲の中で調節することが好ましい。成分（Ａ）の含有量が５５重量％未満であると、組成物を成形してのぞましい成形物にすることが困難となる。それに対して、成分（Ａ）の含有量が７０重量％を超えると、成分（Ｂ）の含有量が相対的に低くなり、そのため吸音性が改善されず、また耐熱性および耐衝撃性も劣ったものとなる。   The content of the component (A) in the resin composition of the present invention is preferably adjusted within the range of 55 to 70% by weight. When the content of the component (A) is less than 55% by weight, it is difficult to mold the composition into a suitable molded product. On the other hand, when the content of the component (A) exceeds 70% by weight, the content of the component (B) is relatively low, so that sound absorption is not improved, and heat resistance and impact resistance are inferior. It will be.

本発明の樹脂組成物に含まれる成分（Ｂ）としては、タルクと硫酸バリウムとの混合物が用いられる。このとき、タルクと硫酸バリウムの重量混合比は、１：９〜９：１の範囲内である。本発明にもとづけば、成分（Ｂ）の含有量および混合比は、本発明の樹脂組成物の吸音度に決定的役割を果たし、最終成形物の処理性および外観に有意の影響をあたえる。混合比が１：９未満であると、十分な吸音性が期待できず、また処理性が悪くなる。混合比が９：１を超えると、吸音性は改善されるが、最終成形物の外観が悪くなり、成形性も低下する。タルクと硫酸バリウムとの混合物の代わりに硫酸バリウムのみを使用すると、タルクのみを使用した場合と比較して吸音性はわずかに改善される。しかし、硫酸バリウムのみを使用すると、硫酸バリウムの高い吸湿性のために成形が困難になる。また、タルクと硫酸バリウムとの混合物の代わりにタルクのみを使用した場合には、硫酸バリウムのみを使用した場合と比較して耐熱性はすぐれたものとなる。しかし、タルクのみを使用すると、外観がわるくなるために成形が困難になる。成分（Ｂ）としてタルクと硫酸バリウムとを組み合わせて使用すると、硫酸バリウムまたはタルクのみを使用した場合に生じる低い吸音性、低い耐熱性、低い耐衝撃性などの問題がなくなる。   As the component (B) contained in the resin composition of the present invention, a mixture of talc and barium sulfate is used. At this time, the weight mixing ratio of talc and barium sulfate is in the range of 1: 9 to 9: 1. According to the present invention, the content and mixing ratio of component (B) play a decisive role in the sound absorption of the resin composition of the present invention, and have a significant influence on the processability and appearance of the final molded product. . If the mixing ratio is less than 1: 9, sufficient sound absorption cannot be expected, and the processability deteriorates. When the mixing ratio exceeds 9: 1, the sound absorption is improved, but the appearance of the final molded product is deteriorated and the moldability is also lowered. When only barium sulfate is used instead of the mixture of talc and barium sulfate, the sound absorption is slightly improved as compared with the case where only talc is used. However, if only barium sulfate is used, molding becomes difficult due to the high hygroscopicity of barium sulfate. In addition, when only talc is used instead of the mixture of talc and barium sulfate, the heat resistance is excellent as compared with the case where only barium sulfate is used. However, when only talc is used, it becomes difficult to mold because the appearance is changed. When talc and barium sulfate are used in combination as the component (B), problems such as low sound absorption, low heat resistance, and low impact resistance that occur when only barium sulfate or talc is used are eliminated.

本発明の樹脂組成物における成分（Ｂ）の含有量は、１５〜５０重量％の範囲の中で調節される。成分（Ｂ）の含有量が１５重量％未満だと、吸音性の改善が期待できない。他方、成分（Ｂ）の含有量が５０％を超えると、最終成形物にすることが困難となり、また、樹脂組成物の重量がのぞましくない程度に増大する。   Content of the component (B) in the resin composition of this invention is adjusted in 15-50 weight%. If the content of the component (B) is less than 15% by weight, improvement in sound absorption cannot be expected. On the other hand, when the content of the component (B) exceeds 50%, it becomes difficult to obtain a final molded product, and the weight of the resin composition increases to an undesired level.

本発明の樹脂組成物の中の成分（Ｃ）の含有量は、樹脂組成物の重量を下げまた同時に耐熱性および耐衝撃性を維持しながら強度、硬度、および吸音性を改善するために、１０重量％以下、好ましくは０．０１〜１０重量％の範囲内に調節される。本発明の樹脂組成物から組成（Ｃ）を除外すると、耐熱性および耐衝撃性を維持することができず、樹脂組成物の重量を下げることができず、さらに強度、硬度、および吸音性を改善することができない。他方、成分（Ｃ）が１０重量％を超える量存在すると、成分（Ｂ）の重量を下げる効果がなくなるか或いは少なくなり、価格が上昇し、耐衝撃性が低下する。   The content of the component (C) in the resin composition of the present invention is to reduce the weight of the resin composition and simultaneously improve the strength, hardness, and sound absorption while maintaining heat resistance and impact resistance. It is adjusted within the range of 10% by weight or less, preferably 0.01 to 10% by weight. If the composition (C) is excluded from the resin composition of the present invention, the heat resistance and impact resistance cannot be maintained, the weight of the resin composition cannot be reduced, and the strength, hardness, and sound absorption are further reduced. It cannot be improved. On the other hand, when the component (C) is present in an amount exceeding 10% by weight, the effect of reducing the weight of the component (B) is lost or reduced, the price is increased, and the impact resistance is decreased.

必要な場合には、本発明の樹脂組成物は、さらに（Ｄ）相溶化剤を含む。本発明で使用できる成分（Ｄ）の例としては、末端にカルボキシル基を有するポリエチレン（ＣＯＯＨ−ＰＥ）、末端にカルボキシル基を有するポリプロピレン（ＣＯＯＨ−ＰＰ），末端に無水マレイン酸を有するポリプロピレン（ＭＡＨ−ＰＰ）、ポリ（スチレン−アクリル酸）（Ｐ（Ｓｔ−ＡＡ）、ポリスチレン−ポリイミド・ブロック・コポリマー（ＰＳ−ＰＩ）、ポリスチレン−ポリエチレン・ブロック・コポリマー（ＰＳ−ＰＥ）、スチレン−エチレン−ブタジエン−スチレン・ブロック・コンポリマー（ＳＥＢＳ）、ポリスチレン−ポリメチルメタクリレート・ブロック・コポリマー（ＰＳ−ＰＭＭＡ），ポリスチレン−ポリブチルアジペート・ブロック・コポリマー（ＰＳ−ＰＢＡ）、ポリスチレン−ポリカルプロラクトン・ブロック・コポリマー（ＰＳ−ＰＣＬ）、ポリプロピレン−ポリアミド・グラフト・コポリマー（ＰＰ−ｇ−ＰＡ）、ポリブチレンテレフタレート−ポリアミド・グラフト・コポリマー（ＰＢＴ−ｇ−ＰＡ），ポリプロピレン−無水マレイン酸・グラフト・コポリマー（ＰＰ−ｇ−ＭＡ）、シンジオタクチック・ポリスチレン−無水マレイン酸・グラフト・コポリマー（ｓＰＳ−ｇ−ＭＡ）、およびスチレン−エチレン−ブタジエン−スチレン−無水マレイン酸・グラフト・コポリマー（ＳＥＢＳ−ｇ−ＭＡ）を含み、好ましくは、ポリプロピレン−無水マレイン酸・グラフト・コポリマー（ＰＰ−ｇ−ＭＡ）、シンジオタクチック・ポリスチレン−無水マレイン酸・グラフト・コポリマー（ｓＰＳ−ｇ−ＭＡ）、およびスチレン−エチレン−ブタジエン−スチレン−無水マレイン酸グラフト・コポリマー（ＳＥＢＳ−ｇ−ＭＡ）を含む。ポリプロピレン−無水マレイン酸・グラフト・コポリマー（ＰＰ−ｇ−ＭＡ）が好ましい。   If necessary, the resin composition of the present invention further comprises (D) a compatibilizing agent. Examples of the component (D) that can be used in the present invention include polyethylene having a carboxyl group at the end (COOH-PE), polypropylene having a carboxyl group at the end (COOH-PP), and polypropylene having maleic anhydride at the end (MAH). -PP), poly (styrene-acrylic acid) (P (St-AA), polystyrene-polyimide block copolymer (PS-PI), polystyrene-polyethylene block copolymer (PS-PE), styrene-ethylene-butadiene. -Styrene block copolymer (SEBS), polystyrene-polymethylmethacrylate block copolymer (PS-PMMA), polystyrene-polybutyl adipate block copolymer (PS-PBA), polystyrene-polycarprolactone Lock copolymer (PS-PCL), polypropylene-polyamide graft copolymer (PP-g-PA), polybutylene terephthalate-polyamide graft copolymer (PBT-g-PA), polypropylene-maleic anhydride graft copolymer (PP-g-MA), syndiotactic polystyrene-maleic anhydride graft copolymer (sPS-g-MA), and styrene-ethylene-butadiene-styrene-maleic anhydride graft copolymer (SEBS-g-) MA), preferably polypropylene-maleic anhydride graft copolymer (PP-g-MA), syndiotactic polystyrene-maleic anhydride graft copolymer (sPS-g-MA), and styrene-ethylene Butadiene - styrene - containing maleic anhydride grafted copolymer anhydride (SEBS-g-MA) polypropylene -.

相溶化剤として用いられるポリマーは、通常、ほとんどがブロックまたはグラフト・コポリマーの形で存在し、大きくいって、反応性相溶化剤と非反応性相溶化剤に分けられる。反応性相溶化剤は、機能基が導入されるコポリマーである。少量の反応性相溶化剤でものぞましい物理的性質を得ることができるが、副反応のために物理的性質の劣化が生じるおそれがある。反応性相溶化剤とは異なり、非反応性相溶化剤は、樹脂組成物の練成成形を容易にしまた副反応による物理的性質の劣化がないもしくはほとんどないので、本発明に使用して好ましいものである。相溶化剤は、従来のブロックまたはグラフト・コポリマーの合成方法と同様にして調製される。コポリマーのＰＰ−ｇ−ＭＡ、ｓＰＳ−ｇ−ＭＡおよびＳＥＢＳ−ｇ−ＭＡは、グラフト比０．２〜２．０を示す。本発明の樹脂組成物中の（Ｄ）相溶化剤の含有量は、５重量％を超えないように、好ましくは０．０１〜５重量％の範囲内にあるように制御される。   The polymers used as compatibilizers usually exist mostly in the form of block or graft copolymers and are broadly divided into reactive compatibilizers and non-reactive compatibilizers. A reactive compatibilizer is a copolymer into which functional groups are introduced. Although a small amount of a reactive compatibilizing agent can provide the desired physical properties, the physical properties may be deteriorated due to side reactions. Unlike reactive compatibilizers, non-reactive compatibilizers are preferred for use in the present invention because they facilitate kneading of the resin composition and have little or no physical property degradation due to side reactions. Is. The compatibilizer is prepared in the same manner as conventional block or graft copolymer synthesis methods. The copolymers PP-g-MA, sPS-g-MA and SEBS-g-MA exhibit a graft ratio of 0.2-2.0. The content of the (D) compatibilizing agent in the resin composition of the present invention is controlled so as not to exceed 5% by weight, and preferably in the range of 0.01 to 5% by weight.

Various physical properties and sound-absorbing properties of the tubes produced from the resin composition of the present invention were evaluated according to the test methods shown below.
1) Melt index: The flowability of the resin was measured at 230 ° C. under a load of 2.16 kg based on ASTM D1238 standard test method and expressed in g / min.
2) Specific gravity: Based on the standard test method of ASTM D1505, measurement was performed using buoyancy in a liquid.
3) HDT: A sample (length: 127 mm, width: 12.7 mm, thickness: 6.4 mm) molded using an injection molding machine was used. Samples were tested and measured under loads of 4.6 and 18.5 kgf / cm 2 based on the ASTM D648 standard test method.

４）硬度： ＡＳＴＭ Ｄ２２４０標準試験法にもとづいて、アスカ型Ａジュロメーター（硬度計）上で垂直方向に１０Ｎの負荷を加えた後３０秒間測定を行なった。
５）引っ張り強度および伸張： 厚さ２±０．５ｍｍの試料を使用した。ＡＳＴＭ Ｄ４１２標準試験法にもとづいて、引っ張りテスターを用い、引っ張り速度５０ｍｍ／分で測定を行なった。
６）ビカー軟化点： ＪＩＳ−Ｋ７２０６標準試験法にもとづいて測定を行なった。測定したビカー軟化点を耐熱性の指標として使用した。すなわち、ビカー軟化点が高いほど、耐熱性がよいことになる。

5) Tensile strength and elongation: Samples with a thickness of 2 ± 0.5 mm were used. Based on the ASTM D412 standard test method, measurement was performed using a tensile tester at a pulling speed of 50 mm / min.
6) Vicat softening point: Measured according to JIS-K7206 standard test method. The measured Vicat softening point was used as an index of heat resistance. That is, the higher the Vicat softening point, the better the heat resistance.
7) Spiral flow: Based on the test method developed by the present applicant, an injection molding machine was used to perform injection molding at 230 ° C. to measure fluidity. The obtained result was expressed in centimeters.

８）曲げ強度： ＡＳＴＭ Ｄ７９０標準試験法にもとづいて、５ｍｍ／分の曲げ速度で、負荷が増大しなくなるまで（すなわち、最大負荷まで）管を曲げて測定を行なった。

１１）吸音性： 周波数を変化させながら（ｒａｄ／ｓ）、ｔａｎδ（２３℃）の値を測定し、ｄＢであらわした。ｔａｎδ値が高い（即ち、ｄＢ値が低い）ほど、吸音性が良いこととなる。厚さ３．１ｍｍ、直径４２Φｍｍのパイプを測定に用いた。 8) Bending strength: Measurement was performed by bending the tube at a bending speed of 5 mm / min until the load did not increase (that is, up to the maximum load) based on the ASTM D790 standard test method.
9) Bending elastic modulus: Based on the ASTM D790 standard test method, the tube was bent at a bending speed of 5 mm / min, and a load curve was plotted for measurement. The flexural modulus was obtained from the initial linear slope.
10) Izod impact strength: Measurement was performed using an injection-molded sample having a thickness of 3.2 mm based on the ASTM D256 standard test method.
11) Sound absorption: While changing the frequency (rad / s), the value of tan δ (23 ° C.) was measured and expressed in dB. The higher the tan δ value (that is, the lower the dB value), the better the sound absorption. A pipe having a thickness of 3.1 mm and a diameter of 42 mm was used for the measurement.
