産業上の利用分野
この発明は、フェノール樹脂発泡体の現場施工に特に好
適な発泡性組成物に関する。DETAILED DESCRIPTION OF THE INVENTION Field of the Invention This invention relates to foamable compositions which are particularly suitable for the field application of phenolic resin foams.
従来の技術
硬質ウレタンフオームはスプレー発泡等により現場施工
が可能なために、結露防止等を目的とした断熱材として
建築等の種々の分野で汎用されているが、難燃性が劣る
という欠点があり、例えば建築現場等においては、施工
後に溶接や溶断作業等の火気によって焼失するという火
災事故が頻発している。Conventional technology Rigid urethane foam can be installed on-site by spray foaming, etc., so it is widely used in various fields such as construction as an insulating material to prevent condensation, but it has the disadvantage of poor flame retardancy. For example, at construction sites, there are frequent fire accidents in which materials are destroyed by fire during welding or fusing work after construction.
このため、難燃性だけでなく、断熱性や防音性等にも優
れたフェノール樹脂発泡体が硬質ウレタンフオームの代
替断熱材として使用されるようになっているが、現場施
工が困難なため、温度調整された工場内において予めボ
ード状に成形した後、使用に供しているのが実情である
。For this reason, phenolic resin foam, which is not only flame retardant but also has excellent heat and sound insulation properties, is being used as an alternative insulation material to rigid urethane foam, but it is difficult to install on-site. The reality is that they are first formed into board shapes in a temperature-controlled factory and then put into use.
フェノール樹脂発泡体が現場施工できない主要な原因は
、フェノール樹脂の粘度が高いために、実用的に均一分
散したスプレー状態が得難く、また、低温下では発泡反
応が抑制される結果、表面が脆くて接着性の悪い発泡体
が得られるという点にある。The main reason why phenolic resin foam cannot be applied on-site is that the viscosity of phenolic resin is high, which makes it difficult to obtain a practically uniformly dispersed spray, and the foaming reaction is suppressed at low temperatures, resulting in a brittle surface. The point is that a foam with poor adhesiveness can be obtained.
発明が解決しようとする課題
この発明は、フェノール樹脂発泡体のこのような問題点
を解決し、現場施工、特に壁面等への現場施工も可能な
フェノール樹脂発泡体を提供するためになされたもので
ある。Problems to be Solved by the Invention The present invention has been made in order to solve these problems of phenolic resin foam and to provide a phenolic resin foam that can be installed on-site, especially on walls, etc. It is.
課題を解決するための手段
即ち本発明は、レゾール系フェノール樹脂１００重量部

クロロジフルオロメタン２〜１０重量部、炭酸塩０．０
１〜５重量部、整泡剤１〜１０重量部および硬化剤１０
〜４０重量部含有する発泡性組成物に関する。Means for solving the problem, that is, the present invention, consists of 2 to 10 parts by weight of dichlorotrifluoroethane, 2 to 10 parts by weight of dichlorodifluoromethane, and 0.0 parts by weight of carbonate per 100 parts by weight of resol type phenolic resin.
1 to 5 parts by weight, 1 to 10 parts by weight of foam stabilizer, and 10 parts by weight of curing agent.
-40 parts by weight of a foamable composition.
レゾール系フェノール樹脂としては自体公知のもの、例
えばフェノールやアルキルフェノール等のフェノール類
とホルマリンをｌ：１．ｏ〜１：３゜０、好ましくは１
．５〜２．５のモル比で塩基性触媒（ＮａＯＨ，ＫＯＨ
等）の存在下で反応させて得られるものを適宜使用すれ
ばよい。The resol-based phenolic resin is one that is known per se, for example, phenol such as phenol or alkylphenol and formalin in a ratio of 1:1. o~1:3°0, preferably 1
．． Basic catalysts (NaOH, KOH
etc.) may be used as appropriate.
本発明に使用するレゾール系フェノール樹脂の粘度は通
常約１０００〜５０００ｃｐｓ（２５℃）、好ましくは
約１５００〜２０００ｃｐｓ（２５℃）であり、不揮発
樹脂成分は７０〜８０％、またｐＨは約７〜８である。The viscosity of the resol type phenolic resin used in the present invention is usually about 1000 to 5000 cps (25°C), preferably about 1500 to 2000 cps (25°C), the nonvolatile resin component is 70 to 80%, and the pH is about 7 to 80%. It is 8.
不揮発樹脂成分が８０％以上になると、樹脂粘度が高く
なり過ぎ、機械的送液が困難になるだけでなく、スプレ
ー分散性も悪くなる。When the nonvolatile resin component exceeds 80%, the resin viscosity becomes too high, which not only makes mechanical liquid feeding difficult, but also deteriorates spray dispersibility.
本発明においては、発泡剤としてジクロロトリプルオロ
エタン、ジクロロジフルオロメタンおよび炭酸塩を併用
する。In the present invention, dichlorotriple olethane, dichlorodifluoromethane and carbonate are used in combination as blowing agents.
ジクロロトリフルオロエタンはレゾール系フェノール樹
脂の溶解性が高く、該樹脂の粘度を低下させるのに有効
であり、予め該樹脂に均一に溶解させておけばよい。ジ
クロロトリフルオロエタンの配合量は２〜１０重量部で
あり、２重量部以下では、レゾール系フェノール樹脂の
粘度を十分に低下させることができず、１０重量部以上
になると生成する発泡体の密度が小さくなり過ぎ、実用
的な強度が得られない。Dichlorotrifluoroethane has a high solubility in resol-based phenolic resins and is effective in lowering the viscosity of the resin, and may be uniformly dissolved in the resin in advance. The amount of dichlorotrifluoroethane blended is 2 to 10 parts by weight; if it is less than 2 parts by weight, the viscosity of the resol-based phenolic resin cannot be sufficiently lowered, and if it is more than 10 parts by weight, the density of the foam produced will be reduced. becomes too small and practical strength cannot be obtained.
ジクロロジフルオロメタンは沸点が低いため（−３０℃
）、取扱い上十分な注意を要するが、スプレー時に瞬時
に気化してスプレー分散性を改良すると共に、冬期のよ
うな低温環境下でも発泡体の発泡立上りを遅延させない
ので、施工性を改善する。ジクロロジフルオロメタンの
配合量は２〜ｌ°０重量部であり、２重量部以下では、
スプレー分散性が細くなって発泡体の平滑性が悪くなり
、１０重量部以上になると、スプレー分散性が大きくな
って施工性が悪くなるばかりでなく、空気中への樹脂の
飛散量が多くなり不経済である。Dichlorodifluoromethane has a low boiling point (-30℃
), which requires great care when handling, but improves spray dispersion by instantaneously vaporizing during spraying, and also improves workability as it does not delay the rise of the foam even in low-temperature environments such as in winter. The blending amount of dichlorodifluoromethane is 2 to 1°0 parts by weight, and if it is 2 parts by weight or less,
Spray dispersibility becomes thinner and the smoothness of the foam deteriorates, and if it exceeds 10 parts by weight, not only will spray dispersibility increase and workability deteriorate, but the amount of resin scattered into the air will increase. It is uneconomical.
ジクロロジフルオロメタンは沸点が低いので、通常は、
現場施工時等の使用時に加圧ポンプを用いてレゾール系
フェノール樹脂中へ導入し、スタティックミキサーを用
いて混合する。Dichlorodifluoromethane has a low boiling point, so it is usually
When used during on-site construction, etc., it is introduced into resol-based phenolic resin using a pressure pump and mixed using a static mixer.
炭酸塩としては炭酸カリウムや炭酸ナトリウム等の金属
炭酸塩の外、炭酸アンモニウム等が例示されるが、炭酸
カリウムが最も好ましい。Examples of carbonates include metal carbonates such as potassium carbonate and sodium carbonate, as well as ammonium carbonate, and potassium carbonate is most preferred.
炭酸塩は以下に説明する硬化剤と反応して発熱を伴って
炭酸ガスを発生するので、発泡剤として作用するだけで
なく、発泡体の硬化反応を促進する作用もする。このた
め、冬期の現場等の低温条件下においても発泡体の生成
反応が瞬時に開始し、その硬化反応も可及的速やかにお
こなわれるので、本発明による発泡性組成物は垂直壁面
等にスプレー施工した場合でも、垂れることなく円滑に
発泡硬化をおこなって、平滑な表面を有する均質発泡体
層を形成する。The carbonate reacts with the curing agent described below to generate carbon dioxide gas with heat generation, so it not only acts as a foaming agent but also acts to accelerate the curing reaction of the foam. Therefore, even under low-temperature conditions such as on-site in the winter, the foam formation reaction starts instantly and the curing reaction takes place as quickly as possible, so the foamable composition of the present invention can be sprayed onto vertical walls, etc. Even when applied, the foam hardens smoothly without sagging, forming a homogeneous foam layer with a smooth surface.
炭酸塩の配合量は０．０１〜５重量部であり、０．０１
重量部以下では上記の発熱による硬化促進効果が得られ
ず、５重量部以上になると炭酸ガスが過度に発生するた
めに発泡体の密度が低下し、実用上十分な強度を有する
発泡体が得られない。The blending amount of carbonate is 0.01 to 5 parts by weight, and 0.01
If it is less than 5 parts by weight, the curing accelerating effect due to heat generation cannot be obtained, and if it is more than 5 parts by weight, carbon dioxide gas is generated excessively, resulting in a decrease in the density of the foam, resulting in a foam having sufficient strength for practical use. I can't.

整泡剤の配合量は通常１〜１０重量部であり、１重量部
以下では十分な整泡効果が得難い。１０重量部以上にし
ても整泡効果は変らない。The amount of the foam stabilizer is usually 1 to 10 parts by weight, and if it is less than 1 part by weight, it is difficult to obtain a sufficient foam stabilizer effect. Even if the amount is 10 parts by weight or more, the foam regulating effect remains unchanged.
硬化剤としては無機酸、例えば塩酸、硫酸および燐酸等

できるが、発泡体中の残留酸による金属腐食が問題にな
る場合には有機酸の使用が有利である。Inorganic acids, such as hydrochloric acid, sulfuric acid, and phosphoric acid, or organic acids, such as benzenesulfonic acid, phenolsulfonic acid, and toluenesulfonic acid, can be used as hardeners, but metal corrosion due to residual acid in the foam may be a problem. In such cases, it is advantageous to use organic acids.
硬化剤の配合量は通常１０〜４０重量部であり、１０重
量部以下では十分な硬化効果が得難く、４０重量部以上
になると残留酸による金属腐食の問題だけでなく、難燃
性等の品質にも悪影響を与える。The amount of curing agent blended is usually 10 to 40 parts by weight; if it is less than 10 parts by weight, it is difficult to obtain a sufficient curing effect, and if it is more than 40 parts by weight, not only will there be metal corrosion problems due to residual acid, but also problems such as flame retardancy will occur. It also has a negative impact on quality.
