Description
본 발명은 아웃솔용 고무시트 조성물에 관한 것으로, 더욱 상세하게는 로타큐어 성형 공정이 접목된 내마모 및 넌슬립 특성이 개선된 로타큐어 성형 공정이 접목된 아웃솔용 고무시트 조성물 및 이를 이용한 아웃솔용 고무시트 제조방법에 관한 것이다. The present invention relates to a rubber sheet composition for outsole, and more specifically, to a rubber sheet composition for outsole incorporating a rotacure molding process with improved wear resistance and non-slip characteristics, and a rubber for outsole using the same. It relates to a sheet manufacturing method.
최근 생활수준의 향상과 수요자의 다양한 욕구에 의해 다양한 디자인을 가진 수많은 종류의 신발이 제조되고 있으며, 또한 각 기능에 따른 특수신발 역시 다양하게 출시되고 있다. 그러나 이와 같이 다양한 종류로 출시되는 신발의 구조를 살펴보면 대동소이함을 확인할 수 있다. Recently, numerous types of shoes with various designs have been manufactured due to the improvement in living standards and the diverse needs of consumers, and a variety of special shoes according to each function are also being released. However, if you look at the structure of the shoes released in these various types, you can see that they are all very similar.
일반적으로 사용되는 신발은 크게 밑창과 밑창의 상부에 결합되는 갑피로 구성되며, 밑창은 신발의 바닥창을 이루는 아웃솔과 중창을 이루는 미드솔로 구성된다. 아웃솔은 내마모성과 미끄럼 방지를 위한 기능을 충족시킬 수 있도록 고무 재질로 이루어지고, 미드솔은 전체 신발의 무게를 줄여 가벼우면서도 충격을 가했을 때 충격을 흡수 하면서 복원력이 있도록 하기 위해 발포 팽창시킨 합성 수지재를 주로 사용하게 된다. Commonly used shoes are largely composed of a sole and an upper joined to the top of the sole, and the sole is composed of an outsole that forms the sole of the shoe and a midsole that forms the midsole. The outsole is made of rubber material to fulfill the functions of wear resistance and anti-slip, and the midsole is made of foamed and expanded synthetic resin material to reduce the weight of the entire shoe, making it lightweight and absorbing shock when impact is applied while providing resilience. It is mainly used.
밑창을 이루는 아웃솔과 미드솔의 재질이 상이하고 또한 제작 방법이 달라 따로 제작 및 부착이 되도록 성형공정이 이루어지며, 이러한 문제점을 해결하기 위해 미드솔과 아웃솔을 동시에 프레싱 작업을 수행하지만, 미가류 고무의 적정 두께 및 접착력이 요구되는 물성에 현저히 못 미치는 결과를 초래하는 문제점이 있다. The outsole and midsole that make up the sole are made of different materials and have different manufacturing methods, so the molding process is carried out so that they can be manufactured and attached separately. To solve this problem, the midsole and outsole are pressed at the same time, but the unvulcanized rubber is used appropriately. There is a problem that results in thickness and adhesion significantly fall short of the required physical properties.
본 발명은 상술한 문제점을 해결하기 위한 것으로, 본 발명의 목적은 기존 프레스 공정이 아닌 로타큐어 성형 공정이 접목되고, 기존 미드솔과 아웃솔에 적용되는 접착공정이 아닌 핫멜트 필름을 적용한 내마모 및 넌슬립 특성이 개선된 아웃솔용 고무시트 조성물 및 이를 이용한 아웃솔용 고무시트 제조방법을 제공하는 것이다. The present invention is to solve the above-mentioned problems, and the purpose of the present invention is to develop a wear-resistant and non-slip product that combines the rotacure molding process rather than the existing press process and applies a hot melt film rather than the adhesive process applied to the existing midsole and outsole. To provide a rubber sheet composition for outsole with improved properties and a method for manufacturing a rubber sheet for outsole using the same.
상술한 목적을 달성하기 위한 것으로, 본 발명인 로타큐어 성형 공정이 접목된 아웃솔용 고무시트 조성물 및 이를 이용한 아웃솔용 고무시트 제조방법은, 스타이렌 부타디엔 고무(Stylene Butadiene Rubber, SBR), 니트릴 부타디엔 고무(Nitrile Butadiene Rubber, NBR), 폴리부타디엔 고무(Polybutadiene Rubber, BR)를 포함하는 고무기재; 첨가제; 산화방지제; 가황제;를 포함하여 구성되는 것을 특징으로 하며, 상기 첨가제는 실란(Silane), 실리카(Silica), 징크옥사이드(Zinc Oxide, ZnO), 폴리에틸렌글리콜(PolyethyleneGlycol, PEG) 및 스테아린산(Stearic acid)을 포함하는 것을 특징으로 한다. In order to achieve the above-described object, the present inventors' rubber sheet composition for outsole incorporating the Rotacure molding process and the method for manufacturing the rubber sheet for outsole using the same include styrene butadiene rubber (SBR), nitrile butadiene rubber ( Rubber base materials including Nitrile Butadiene Rubber (NBR) and Polybutadiene Rubber (BR); additive; Antioxidants; It is characterized by comprising a vulcanizing agent, and the additives include silane, silica, zinc oxide (ZnO), polyethylene glycol (PEG), and stearic acid. It is characterized by:

이하, 본 발명인 로타큐어 성형 공정이 접목된 아웃솔용 고무시트 조성물 및 이를 이용한 아웃솔용 고무시트의 바람직한 실시예가 첨부된 도면을 참고하여 상세하게 설명한다.Hereinafter, a preferred embodiment of a rubber sheet composition for outsole incorporating the rotacure molding process of the present invention and a rubber sheet for outsole using the same will be described in detail with reference to the accompanying drawings.
본 발명에 의한 로타큐어 성형 공정이 접목된 아웃솔용 고무시트 조성물은, 스타이렌 부타디엔 고무(Stylene Butadiene Rubber, SBR), 니트릴 부타디엔 고무(Nitrile Butadiene Rubber, NBR), 폴리부타디엔 고무(Polybutadiene Rubber, BR)를 포함하는 고무기재; 첨가제; 산화방지제; 가황제;를 포함하여 구성될 수 있다. The rubber sheet composition for outsole incorporating the rotacure molding process according to the present invention includes styrene butadiene rubber (SBR), nitrile butadiene rubber (NBR), and polybutadiene rubber (BR). A rubber base containing; additive; Antioxidants; It may be composed of a vulcanizing agent.
상기 고무기재는 스타이렌 부타디엔 고무, 니트릴 부타디엔 고무, 폴리부타디엔 고무를 포함할 수 있다. 구체적으로, 스타이렌 부타디엔 고무 10중량부에 대하여 니트릴 부타디엔 고무 30 내지 50중량부, 폴리부타디엔 고무 40 내지 50중량부를 포함할 수 있다. The rubber base may include styrene butadiene rubber, nitrile butadiene rubber, and polybutadiene rubber. Specifically, it may include 30 to 50 parts by weight of nitrile butadiene rubber and 40 to 50 parts by weight of polybutadiene rubber based on 10 parts by weight of styrene butadiene rubber.
스타이렌 부타디엔 고무(Stylene Butadiene Rubber, SBR)은 부타디엔과 스타이렌을 저온유화중합하여 만든 공중합체로, 합성고무중 가장 일반적으로 사용되는 범용고무이며, 천연고무에 비하여 내마모성, 내열성이 우수한 장점과 가황이 평탄하고 안정된 스코치(Scorch)성과 용이한 가공성 등 폭넓게 사용이 가능한 물성을 지니고 있다. 그래서 타이어, 신발, 고무호스, 벨트 등 대부분의 고무제품에 사용되고 있다. Styrene Butadiene Rubber (SBR) is a copolymer made by low-temperature emulsion polymerization of butadiene and styrene. It is the most commonly used general-purpose rubber among synthetic rubbers. It has superior abrasion resistance and heat resistance compared to natural rubber and is vulcanized. It has properties that allow for a wide range of uses, such as flat and stable scorch properties and easy processability. Therefore, it is used in most rubber products such as tires, shoes, rubber hoses, and belts.
니트릴 부타디엔 고무(Nitrile Butadiene Rubber, NBR)는 유화중합에 의하여 제조된 아크릴로니트릴과 부타디엔의 공중합체로, 가장 널리 사용되고 있는 내유성고무이다. 니트릴함량이 42~46%의 극고니트릴, 36~41%의 고니트릴, 31~35%의 중고니트릴, 25~30%의 저 니트릴등으로 분류되며, 니트릴함량의 증대에 따라서 내유성, 내마모성, 기계적 성질이 향상되지만 내한성, 신장성, 탄성은 저하된다. 이에 인쇄용롤, 내유성호스, 자동차용 부품 등에 널리 사용된다.Nitrile Butadiene Rubber (NBR) is a copolymer of acrylonitrile and butadiene produced by emulsion polymerization, and is the most widely used oil-resistant rubber. Nitrile content is classified into extreme high nitrile with 42~46%, high nitrile with 36~41%, medium nitrile with 31~35%, and low nitrile with 25~30%. As nitrile content increases, oil resistance, wear resistance, and mechanical properties improve. Properties improve, but cold resistance, extensibility, and elasticity decrease. Therefore, it is widely used in printing rolls, oil-resistant hoses, and automobile parts.
폴리부타디엔 고무(Polybutadiene Rubber, BR)는 1,3-butadiene을 용액 중합하여 제조한 단중합체로서 cis-1,4, trans-1,4, viny1 구조의 3가지 결합형태를 가지고 있으며, cis-1,4의 함량에 따라 High cis BR 과 Low cis BR로 분류된다. 천연고무, SBR에 다음가는 범용고무이며 타이어, 벨트, 호오스, 신발 등에 사용된다. Polybutadiene Rubber (BR) is a monopolymer produced by solution polymerization of 1,3-butadiene and has three bond forms: cis-1,4, trans-1,4, and vinyl1 structures, and cis-1. Depending on the content of ,4, it is classified into High cis BR and Low cis BR. It is a general-purpose rubber next to natural rubber and SBR and is used in tires, belts, hoses, shoes, etc.
여기서, 상기 스타이렌 부타디엔 고무 10중량부에 대하여 니트릴 부타디엔 고무가 30중량부 미만으로 포함된다면 내유성이 저하되며, 인장강도, 인장탄성율이 감소되며, 50중량부 초과로 혼합된다면 탄성이 저하되는 문제점이 있을 수 있다. 그리고, 니트릴 부타디엔 고무 내에 아크릴로 니트릴의 함량이 낮은 고무를 사용할 경우에는 무늬점도가 높아 카렌더 가공성이 저하되며, 아크릴로 니트릴의 함량이 높은 고무를 사용할 경우 인장강도, 인장응력 증대 및 내유성이 증대될 수 있다. Here, if the nitrile butadiene rubber is included in less than 30 parts by weight relative to 10 parts by weight of the styrene butadiene rubber, the oil resistance is reduced, the tensile strength and tensile modulus are reduced, and if it is mixed in more than 50 parts by weight, the elasticity is reduced. There may be. In addition, when a rubber with a low acrylonitrile content is used in the nitrile butadiene rubber, the pattern viscosity is high and calendering processability is reduced, and when a rubber with a high acrylonitrile content is used, the tensile strength, tensile stress, and oil resistance are increased. You can.
또한, 상기 스타이렌 부타디엔 고무 10중량부에 대하여 폴리부타디엔 고무가 40중량부 미만으로 포함된다면 높은 탄성, 내마모성을 기대할 수 없으며, 50중량부 초과로 혼합된다면 가교속도가 높아져 가공중에 스코치 발생 우려가 증대되고, 미끄러짐 특성 증대로 인한 가공성이 좋지않은 문제점이 있을 수 있다. 그리고, 폴리부타디엔 고무 사용에 따라 실리콘 고무를 쓰지 않고도 내마모성 개선이 가능하며, 점도 저하로 인해 가공성이 증대될 수 있다.In addition, if the polybutadiene rubber is included in less than 40 parts by weight relative to 10 parts by weight of the styrene butadiene rubber, high elasticity and wear resistance cannot be expected, and if it is mixed in excess of 50 parts by weight, the crosslinking speed increases, increasing the risk of scorch occurring during processing. There may be a problem of poor machinability due to increased slip characteristics. In addition, by using polybutadiene rubber, wear resistance can be improved without using silicone rubber, and processability can be increased due to a decrease in viscosity.
상기 첨가제는 실란, 실리카, 징크옥사이드, 폴리에틸렌글리콜 및 스테아린산을 포함할 수 있다. 구체적으로, 실란 1중량부에 대하여 실리카 30 내지 40중량부, 징크옥사이드 5중량부, 폴리에틸렌글리콜 2중량부 및 스테아린산 1중량부를 포함할 수 있다. The additives may include silane, silica, zinc oxide, polyethylene glycol, and stearic acid. Specifically, it may include 30 to 40 parts by weight of silica, 5 parts by weight of zinc oxide, 2 parts by weight of polyethylene glycol, and 1 part by weight of stearic acid based on 1 part by weight of silane.
실리카와 활성화제인 실란을 함께 포함하면 흐름성이 향상되고, 가교시간이 단축되는 이점이 있다. 또한, 가교밀도 상승으로 내마모성, 인장강도, 인열강도 등 전체적인 물성이 향상되는 효과가 있다. Including silica and silane, an activator, has the advantage of improving flowability and shortening crosslinking time. In addition, the increase in crosslinking density has the effect of improving overall physical properties such as wear resistance, tensile strength, and tear strength.
여기서, 상기 실란 1중량부에 대하여 실리카가 30중량부 미만으로 포함된다면 내마모 특성이 저하되고, 신율이 증대되고, 기계적 강도가 저하될 수 있으며, 40중량부 초과로 포함된다면 경도 증가로 인해 내슬립 특성이 저하될 수 있다. 따라서 상기 실란 1중량부에 대하여 실리카가 30 내지 40중량부를 포함하는 경우 적절한 기계강도가 유지되고 표면적 증대로 인해 접착력이 증대될 수 있다. Here, if silica is included in an amount of less than 30 parts by weight relative to 1 part by weight of the silane, wear resistance characteristics may decrease, elongation may increase, and mechanical strength may decrease, and if it is included in more than 40 parts by weight, hardness may increase due to increased hardness. Slip characteristics may deteriorate. Therefore, when 30 to 40 parts by weight of silica is included relative to 1 part by weight of silane, appropriate mechanical strength can be maintained and adhesion can be increased due to increased surface area.
상기 산화방지제는 부틸화히드록시톨루엔(Butylated Hydroxytoluene, BHT), 페놀산화방지제(Antioxidants for polymer resins)를 포함할 수 있다. 구체적으로, 부틸화히드록시톨루엔 1중량부에 대하여 페놀산화방지제 0.5중량부를 포함할 수 있다. The antioxidant may include butylated hydroxytoluene (BHT) and phenol antioxidants (Antioxidants for polymer resins). Specifically, it may contain 0.5 parts by weight of phenol antioxidant based on 1 part by weight of butylated hydroxytoluene.
산화방지제 사용 시 내오존성, 내자외선 변화 특성이 개선되며, 미사용시에는 오존테스트시 크랙이 발생되는 문제점이 있다. When antioxidants are used, ozone resistance and UV resistance change characteristics are improved, but when not used, there is a problem of cracks occurring during ozone testing.
상기 가황제는 황(S)를 사용하고, 가황촉진제인 디벤조티아질 디설파이(Dibenzothiazyl Dissulfide, DM), 테트라메틸 티우람 디술피드(Tetramethyl Thiuram Monosulfide, TT)를 더 포함할 수 있다. 구체적으로, 황 2중량부에 대하여 디벤조티아질 디설파이드 0.4중량부, 테트라메틸 티우람 디술피드 0.15중량부를 포함할 수 있다. The vulcanizing agent uses sulfur (S) and may further include vulcanization accelerators Dibenzothiazyl Dissulfide (DM) and Tetramethyl Thiuram Monosulfide (TT). Specifically, it may include 0.4 parts by weight of dibenzothiazyl disulfide and 0.15 parts by weight of tetramethyl thiuram disulfide based on 2 parts by weight of sulfur.
그리고, 상기 고무기재 100중량부에 대하여 첨가제 35 내지 50중량부를 포함할 수 있다. 구체적으로, 상기 고무기재 100중량부에 대하여 첨가제 39 내지 49중량부를 포함할 수 있다. Additionally, it may contain 35 to 50 parts by weight of additives based on 100 parts by weight of the rubber base. Specifically, it may include 39 to 49 parts by weight of additives based on 100 parts by weight of the rubber base.
여기서, 상기 고무기재 100중량부에 대하여 첨가제가 39중량부 미만으로 포함된다면 인장강도, 인열강도 등 기계적 강도가 감소하는 문제점이 있으며, 첨가제가 49중량부 초과로 포함된다면 높은 탄성, 내마모성을 기대할 수 없다. Here, if the additive is included in an amount of less than 39 parts by weight relative to 100 parts by weight of the rubber base, there is a problem that mechanical strength such as tensile strength and tear strength is reduced, and if the additive is included in an amount exceeding 49 parts by weight, high elasticity and abrasion resistance can be expected. I can't.
그리고, 상기 아웃솔용 고무시트 조성물은 로타큐어에서 성형하여 제조된다. 구체적으로, 상기 아웃솔용 고무시트 조성물은 로타큐어에서 170 내지 175℃의 온도에서 성형하여 제조할 수 있다. In addition, the rubber sheet composition for the outsole is manufactured by molding at Rotacure. Specifically, the rubber sheet composition for the outsole can be manufactured by molding at a temperature of 170 to 175 ° C. in Rotacure.
그리고, 상기 아웃솔용 고무시트 조성물은 핫멜트 수지를 더 포함할 수 있으며, 구체적으로 아웃솔용 고무시트 조성물은 핫멜트 수지인 핫멜트 TPU(Thermoplastic Polyurethane)를 더 포함하여 제조될 수 있다. In addition, the rubber sheet composition for an outsole may further include a hot melt resin. Specifically, the rubber sheet composition for an outsole may be manufactured by further including hot melt TPU (Thermoplastic Polyurethane), which is a hot melt resin.

표 11 및 도 21에 나타난 바와 같이, 실시예 25와 실시예 28이 성능 목표치를 모두 만족하였으며, 점착성도 다른 혼합물에 비해 낮은 것을 확인할 수 있었다. As shown in Table 11 and Figure 21, both Examples 25 and 28 satisfied the performance targets, and it was confirmed that the adhesion was lower than that of other mixtures.
(ㅁ) 본 실험에서는 앞에서 실험한 배합 중 성능이 우수한 실시예 25와 실시예 28의 경도가 다소 높아 이를 조절하기 위해 실리카를 감량하여 특성을 평가하고자 하였다. (ㅁ) In this experiment, the hardness of Examples 25 and 28, which had excellent performance among the mixtures tested previously, was somewhat high, so in order to control this, the properties were evaluated by reducing the amount of silica.
본 실험에서는 실리카의 함량이 줄어들 경우에 경도 저하와 함께 기계적 강도의 저하도 나타나기 때문에 이를 고려하여 함량비를 선정한 후 테스트를 진행하였다. In this experiment, when the silica content decreases, hardness decreases and mechanical strength decreases, so the content ratio was selected with this in mind and then the test was conducted.
