Description
본 발명은 신발용 열가소성 탄성체 조성물에 관한 것으로서, 더욱 상세하게는 스티렌계 열가소성 탄성체 복합체를 기재로 하고 여기에 열안정제, 산화방지제, 자외선안정제 및 통상의 첨가제가 함유되어 있는 열가소성 탄성체 조성물에 있어서, 상기 조성물 중 기재로서 스티렌계 열가소성 탄성체 단독, 또는 스티렌계 열가소성 탄성체와 폴리스티렌계 수지와의 블렌드물을 사용하고, 여기에 흐름성 개선제, 충전제 및 내마모성 향상제를 함유시켜 내마모성, 내구성 및 제반물성이 뛰어나고 흐름성이 높아 고분자 물질의 성형에 적합한 신발용 열가소성 탄성체 조성물에 관한 것이다.The present invention relates to a thermoplastic elastomer composition for shoes, and more particularly, to a thermoplastic elastomer composition based on a styrene-based thermoplastic elastomer composite and containing a heat stabilizer, an antioxidant, an ultraviolet stabilizer, and a conventional additive. Styrene-based thermoplastic elastomer alone or a blend of styrene-based thermoplastic elastomer and polystyrene-based resin is used as a base material in the composition, and it contains a flow improver, a filler, and an anti-wear enhancer, thereby providing excellent wear resistance, durability, and overall properties and flowability. The present invention relates to a thermoplastic elastomer composition for footwear suitable for molding a high molecular material.
열가소성 탄성체는 일반적으로 스포츠화, 부츠, 슬리퍼, 군화 등의 신발용의 겉창재 뿐만 아니라 절연재, 칩 케이스 등의 전기·전자재, 기어 손잡이, 보조 손잡이, 운전대 커버 및 도어 트림 등의 자동차재, 기타 완구류, 스포츠용품, 호스, 튜브, 장식재 등의 다양한 용도로 사용될 수 있다.Thermoplastic elastomers are generally used for footwear, such as sports shoes, boots, slippers, and boots, as well as electrical and electronic materials such as insulation materials and chip cases, automotive materials such as gear handles, auxiliary handles, steering wheel covers, and door trims, etc. It can be used for various purposes such as toys, sporting goods, hoses, tubes, decorative materials.
이중 현재 사용되고 있는 신발용 겉창 소재로는 열경화성 고무가 가장 일반화된 소재이며, 이로 인해 생산기술 또한 프레스에 의한 압축성형으로 제한되어 작업인력 집중에 의한 가격상승과 원소재에 대한 근본적인 물성한계를 야기하므로 제품의 고부가가치와 가격 경쟁력을 얻지 못하고 있어 새로운 소재 및 생산방식의 적용이 필수적이라 하겠다.Among them, thermosetting rubber is the most common material used for shoe outsole, and production technology is also limited to compression molding by press, which raises the price due to the concentration of workforce and fundamental property limits for raw materials. The application of new materials and production methods is indispensable because the products are not gaining high value and price competitiveness.
상기 열가소성 탄성체는 자체 비중이 1이하로서 상기 열경화성 고무에 비하여 10%이상 경량화할 수 있으며, 또한 플라스틱과 같이 사출 생산이 가능하기 때문에 대량생산 체제에 적합한 재료이지만, 신발 겉창 소재로 사용되기에는 현저히 떨어지는 물성 한계로 인해 제한적으로 사용되고 있는 실정이다.The thermoplastic elastomer has a specific gravity of 1 or less and can be reduced by more than 10% compared to the thermosetting rubber, and is also suitable for mass production because it can be injected and produced like plastic, but it is considerably inferior to being used as a shoe outsole material. Due to the physical property limitations are limited use.
이에, 본 발명자들은 종래 상기와 같은 문제점을 해결하기 위하여, 종래 열가소성 탄성체 조성물 중 기재로서 스티렌계 열가소성 탄성체 단독 또는 스티렌계 열가소성 탄성체와 폴리스티렌 수지와의 블렌드물을 기재로 하고, 다양한 첨가제를 투입하여 사출, 압출 및 열프레스 성형함으로써, 내마모성, 내구성 및 제반물성이 뛰어나고 흐름성이 높아 고분자 물질의 성형에 적합한 신발용 열가소성 탄성체 조성물을 제공하는데 그 목적이 있다.In order to solve the above problems, the present inventors use a styrene-based thermoplastic elastomer alone or a blend of a styrene-based thermoplastic elastomer and a polystyrene resin as a substrate in a conventional thermoplastic elastomer composition, and inject various additives to inject the same. It is an object of the present invention to provide a thermoplastic elastomer composition for footwear suitable for molding a polymer material by extrusion, hot press molding, and excellent wear resistance, durability and various physical properties and high flowability.
본 발명은 스티렌계 열가소성 탄성체를 기재로 하고, 여기에 산화방지제, 자외선 안정제 및 통상의 첨가제가 함유되어 있는 열가소성 탄성체 조성물에 있어서,The present invention is based on a styrenic thermoplastic elastomer, in which the thermoplastic elastomer composition containing an antioxidant, a UV stabilizer and a usual additive,
상기 기재로는 스티렌계 열가소성 탄성체 단독, 또는 스티렌계 열가소성 탄성체 70 ∼ 95 중량부와 통상적인 폴리스티렌(general purpose polystyrene: GPPS) 및 고내충격성 폴리스티렌(high impact polystyrene: HIPS) 중에서 선택된 폴리스티렌계 수지 5 ∼ 30 중량부가 블렌드된 블렌드물이 사용되고, 상기 기재 100 중량부에 대하여 폴리올레핀계 수지 및 가소제 중에서 선택된 흐름성 개선제 5 ∼ 50 중량부, 충전제로서 실리카 3 ∼ 50 중량부, 내마모성 향상제 0.5 ∼ 20 중량부 및 실란 커플링제 0.2 ∼ 20 중량부가 함유되어 있는 신발용 열가소성 탄성체 조성물을 그 특징으로 한다.The substrate may include styrene-based thermoplastic elastomers alone, or polystyrene-based resins 5 to 30 selected from 70 to 95 parts by weight of styrene-based thermoplastic elastomers, and general purpose polystyrene (GPPS) and high impact polystyrene (HIPS). Blended parts blended by weight are used, and 5 to 50 parts by weight of a flow improver selected from polyolefin resins and plasticizers, 3 to 50 parts by weight of silica as a filler, 0.5 to 20 parts by weight of abrasion resistance improver, and silane based on 100 parts by weight of the substrate. It is characterized by the thermoplastic elastomer composition for shoes which contains 0.2-20 weight part of coupling agents.
이와 같은 본 발명을 더욱 상세하게 설명하면 다음과 같다.The present invention will be described in more detail as follows.
본 발명에서 열가소성 탄성체를 이용한 신발용 조성물을 제조하기 위하여 스티렌계 열가소성 탄성체를 단독으로 사용하거나, 또는 내후성이 우수한 스티렌계 열가소성 탄성체와 폴리스티렌 수지인 통상적으로 사용되는 폴리스티렌(general purpose polystyrene: GPPS) 및 고내충격성 폴리스티렌(high impact polystyrene: HIPS) 중에서 선택된 것을 블렌드하여 사용한다. 즉, 본 발명에 따른 열가소성 탄성체 조성물에 기재로서는 스티렌계 열가소성 탄성체를 단독으로 사용하거나, 또는 경도조절을 위하여 스티렌계 열가소성 탄성체 70 ∼ 95 중량부와 폴리스티렌계 수지 5 ∼ 30 중량부를 블렌드하여 사용할 수 있다. 이때, 상기 스티렌계 열가소성 탄성체의 함량이 상기 범위 미만이면 경도상승의 효과가 미비하고, 반면 상기 범위를 초과하면 흐름성 저하 및 경도가 탄성범위를 벗어나는 문제가 있다.In the present invention, in order to prepare a shoe composition using a thermoplastic elastomer, a styrene-based thermoplastic elastomer is used alone, or a polystyrene (general purpose polystyrene (GPPS)) and a high temperature which are styrene-based thermoplastic elastomer and a polystyrene resin having excellent weather resistance. Blends selected from high impact polystyrene (HIPS) are used. That is, as the substrate in the thermoplastic elastomer composition according to the present invention, a styrene-based thermoplastic elastomer may be used alone, or 70 to 95 parts by weight of a styrene-based thermoplastic elastomer and 5 to 30 parts by weight of a polystyrene resin may be used for hardness control. . At this time, if the content of the styrene-based thermoplastic elastomer is less than the range, the effect of increasing the hardness is insignificant, whereas if the content of the styrene-based thermoplastic elastomer exceeds the above range, there is a problem that the flowability and hardness is out of the elastic range.
본 발명에서는 사출성형시 가공성 향상을 위하여 흐름성 개선제로서 폴리올레핀계 수지 및 가소제 중에서 선택하여 사용하는 것이 가능하다. 폴리올레핀계 수지로는 폴리프로필렌 수지, 폴리에틸렌 수지, 에틸렌-비닐 아세테이트 수지, 에틸렌-α올레핀 수지 중에서 선택하여 사용하며, 가소제로는 파라핀계 오일, 나프텐계 오일, 방향족계 오일 및 이들의 혼합물 중에서 선택하여 사용할 수 있다.In the present invention, in order to improve processability during injection molding, it is possible to use a polyolefin resin and a plasticizer as a flow improving agent. The polyolefin resin may be selected from polypropylene resin, polyethylene resin, ethylene-vinyl acetate resin, and ethylene-αolefin resin, and the plasticizer may be selected from paraffinic oil, naphthenic oil, aromatic oil, and mixtures thereof. Can be used.
또한, 본 발명에서 열가소성 탄성체 조성물의 내마모성 향상을 위하여 보강성 충전제를 사용할 수 있으며, 이러한 충전제로는 입자크기가 아주 작아 조성물에 고르게 분산되어 물성을 저하시키지 않아야 하기 때문에 일반적으로 건식법 실리카가 가장 적합하다. 건식법 실리카는 사용량에 따라 열가소성 탄성체 조성물의 경도와 물리적 특성을 좌우하는데, 건식법 실리카의 경우 그 사용량은 기재 100 중량부에 대하여 3 ∼ 50 중량부로 사용하는 것이 바람직하다. 이때, 상기 충전제로 사용되는 실리카의 함량이 3 중량부 미만으로 사용할 때는 물성향상 효과가 나타나지 않고, 반면 50 중량부를 초과하여 사용시 경도가 높게 나타나는 문제가 있다.In addition, in the present invention, reinforcing fillers may be used to improve abrasion resistance of the thermoplastic elastomer composition. As such fillers, generally, dry silica is most suitable because the particle size is so small that it should be uniformly dispersed in the composition so as not to degrade physical properties. . Dry silica determines the hardness and physical properties of the thermoplastic elastomer composition depending on the amount of use. In the case of dry silica, the amount is preferably 3 to 50 parts by weight based on 100 parts by weight of the substrate. At this time, when the content of the silica used as the filler is less than 3 parts by weight does not appear to improve the physical properties, while when used in excess of 50 parts by weight there is a problem that the hardness is high.
또한, 본 발명은 열가소성 탄성체 조성물의 내마모성 향상을 위하여 내마모 향상제로서 폴리옥테나머, 불소고무, 테프론 파우더, 스테아린산 아미드, 황화몰리브덴, 실리콘 고무 및 실리콘 오일 중에서 선택하여 단독 또는 혼합 사용할 수 있다. 그 사용함량은 기재 100 중량부에 대하여 0.5 ∼ 20 중량부로 사용하며, 이때 상기 범위를 한정하는 이유는 상기 범위 미만이면 충분한 효과를 얻을 수 없으며, 상기 범위를 초과하면 내마모성 향상효과가 없으면서 제반 물성도 저하되기때문이다.In addition, the present invention can be used alone or in combination of polyoctenamer, fluorine rubber, teflon powder, stearic acid amide, molybdenum sulfide, silicone rubber and silicone oil as an anti-wear enhancer for improving the wear resistance of the thermoplastic elastomer composition. The content is used in an amount of 0.5 to 20 parts by weight based on 100 parts by weight of the base material, and the reason for limiting the above range is not enough effect to be obtained if it is less than the above range. Because it is degraded.
본 발명은 열가소성 탄성체의 내구성 향상을 위하여 통상의 열안정제, 산화방지제 및 자외선 안정제를 단독 또는 혼합 사용할 수 있다.The present invention may be used alone or in combination of conventional heat stabilizers, antioxidants and ultraviolet stabilizers to improve the durability of the thermoplastic elastomer.
이러한 열안정제로는 카드뮴(Cd), 바륨(Ba), 아연(Zn) 및 칼슘(Ca) 중에서 선택된 금속을 함유하고 있는 금속 스테아레이트로서 기재 100 중량부에 대하여 0.1 ∼ 3 중량부로 사용할 수 있다.As such a heat stabilizer, a metal stearate containing a metal selected from cadmium (Cd), barium (Ba), zinc (Zn), and calcium (Ca) may be used in an amount of 0.1 to 3 parts by weight based on 100 parts by weight of the substrate.
산화방지제로는 페놀계 및 아릴아민계 산화방지제 중에서 선택된 1차 산화방지제와, 포스파이트계 및 티오에스터계 산화방지제 중에서 선택된 2차 산화방지제 중에서 선택하여 기재 100 중량부에 대하여 0.1 ∼ 5 중량부로 사용될 수 있다.The antioxidant may be selected from primary antioxidants selected from phenolic and arylamine antioxidants and secondary antioxidants selected from phosphite and thioester antioxidants and used as 0.1 to 5 parts by weight based on 100 parts by weight of the substrate. Can be.
또한, 자외선 안정제로는 하이드록시 벤조페논계, 하이드록시페닐 벤조트리아졸계, 살리실레이트, 벤조에이트 및 시아노아크릴레이트계의 자외선 흡수제, 니켈화합물을 이용한 퀀처(guencher), 하이드로퍼옥사이드 분해제, 라디칼 포착제인 할스(HALS, Hindered Amine Light Stabilizer)가 기재 100 중량부에 대하여 0.1 ∼ 5 중량부로 사용될 수 있다.In addition, UV stabilizers include hydroxy benzophenone-based, hydroxyphenyl benzotriazole-based, salicylate, benzoate and cyanoacrylate-based ultraviolet absorbers, quenchers using nickel compounds, hydroperoxide decomposers, A radical scavenger HLS (Hindered Amine Light Stabilizer) may be used in an amount of 0.1 to 5 parts by weight based on 100 parts by weight of the substrate.
더욱이 본 발명에서는 물성 향상을 위해서 실란 커플링제를 사용할 수 있는데, 본 발명에서 사용되는 실란 커플링제의 종류로는 비닐트리메톡시실란, 비닐트리에톡시실란, 비닐트리클로로실란, 비닐트리(2-메톡시에톡시)실란, 3-아미노프로필에톡시실란, 머캅토프로필트리메톡시실란, 2-(3,4-에폭시사이클로헥실)에틸트리메톡시실란, 3-글리시딜옥시프로필트리메톡시실란, 3-글리시딜옥시프로필메틸디에톡시실란 및 비스-(3-(트리에톡시실릴)-프로필)테트라설파이드 중에서 선택된 것을사용할 수 있다. 상기 실란 커플링제의 사용량은 기재 100 중량부에 대하여 0.2 ∼ 20 중량부로 사용하는 것이 바람직하다. 이때, 실란 커플링제를 0.2 중량부 미만으로 사용할 경우 첨가 효과가 없으며, 반면 20 중량부를 넘을 경우 첨가량에 비해 물성향상이 미비하여 경제성면에서 불리하게 된다.In addition, in the present invention, a silane coupling agent may be used to improve physical properties, and examples of the silane coupling agent used in the present invention include vinyltrimethoxysilane, vinyltriethoxysilane, vinyltrichlorosilane, and vinyltri (2- Methoxyethoxy) silane, 3-aminopropylethoxysilane, mercaptopropyltrimethoxysilane, 2- (3,4-epoxycyclohexyl) ethyltrimethoxysilane, 3-glycidyloxypropyltrimethoxy Any selected from silane, 3-glycidyloxypropylmethyldiethoxysilane and bis- (3- (triethoxysilyl) -propyl) tetrasulfide can be used. It is preferable to use the usage-amount of the said silane coupling agent at 0.2-20 weight part with respect to 100 weight part of base materials. In this case, when the silane coupling agent is used in less than 0.2 parts by weight, there is no addition effect, whereas when it exceeds 20 parts by weight, the physical properties are not improved compared to the added amount, which is disadvantageous in terms of economics.
