인테리어 시트용 폴리올레핀 수지조성물{Polyolefin resin composition for interior seat}Polyolefin resin composition for interior seats

본 발명은 인테리어 시트용 폴리올레핀 수지조성물에 관한 것이다.The present invention relates to a polyolefin resin composition for interior sheets.

건축물의 내장재 및 가구업계에서는 폴리염화비닐(Poly Vinyl Chloride : 이하 PVC)의 시트소재를 사용하고 있으나, PVC는 특성상 할로겐 원소와 중금속을 함유하고 있기 때문에 소각할 경우 유해물질인 다이옥신이 발생하고, 매립처분할 경우에도 납이온의 침출 등으로 환경을 오염시킨다. 더군다나 화재가 일어날 경우 PVC가 타면서 많은 연기와 독가스를 발생시켜 인명 및 재산피해를 증대시키므로 PVC 환경유해로 인한 국제적 사용규제에 대응하는 환경친화적인 소재로 PVC가 가진 내구성, 내스크라치성, 가공성을 겸비한 폴리올레핀계 방염, 비방염 인테리어용 시트소재를 개발하여 PVC의 대체소재로 적용할 필요성이 절실히 요구되고 있는 실정이다.In the building materials and furniture industry, polyvinyl chloride (PVC) sheet material is used.However, since PVC contains halogen elements and heavy metals, dioxin, a hazardous substance, is generated when incinerated and landfilled. Even when disposed of, it pollutes the environment by leaching lead ions. Furthermore, in case of a fire, PVC burns and generates a lot of smoke and poisonous gas, which increases the lives and property damages.It is an environmentally-friendly material that responds to international usage regulations due to PVC environmental damage. There is an urgent need to develop a polyolefin-based flame retardant and non-flameproof interior sheet material and apply it as a substitute material for PVC.

본 발명은 전술한 문제점을 해결하기 위하여 안출된 것으로, 친환경적인 소재로 소각시 유동가스 제거 및 난연제를 사용한 방염소재와 비방염소재의 용도에 따라 적용이 가능하고, 종래 마감제로는 대응이 불가능한 새집증후군 등을 방지할 수 있고, 커팅성, 신장성을 구비하여 가공이 용이하고, 난연성을 구비하여 쉽게 타지 않으며, 천연적인 질감을 나타낼 수 있어 심미감을 줄 수 있는 인테리어 시트용 폴리올레핀 수지조성물을 제공하는 데 그 목적이 있다.The present invention has been made to solve the above-mentioned problems, it is applicable to the use of flame retardant and non-flame retardant material using the flow gas removal and flame retardant when incinerated in an environmentally friendly material, the bird's house syndrome that can not respond to conventional finishes It is possible to prevent, etc., and to provide a polyolefin resin composition for interior sheets that can be easily processed by providing cutting properties and elongation, and not easily burned due to flame retardancy, and can exhibit a natural texture. The purpose is.

전술한 목적을 달성하기 위한 본 발명의 인테리어 시트용 폴리올레핀 수지조성물은, 폴리플로필렌, 고밀도 폴리에틸렌, 저밀도 폴리에틸렌, 선형저밀도 폴리에틸렌, 에틸렌 초산 비닐 공중합체를 포함하여 이루어지되, 상기 폴리플로필렌, 고밀도 폴리에틸렌, 저밀도 폴리에틸렌, 선형저밀도 폴리에틸렌, 에틸렌 초산 비닐 공중합체는 각각 0.90 g/cc 내지 0.98 g/cc의 밀도와 0.1 g/10min 내지 3.0 g/10min의 용융지수를 가지는 것을 특징으로 한다.Polyolefin resin composition for interior sheets of the present invention for achieving the above object is made, including polyflopropylene, high density polyethylene, low density polyethylene, linear low density polyethylene, ethylene vinyl acetate copolymer, the polyflopropylene, high density polyethylene , Low density polyethylene, linear low density polyethylene, ethylene vinyl acetate copolymer is characterized in that each has a density of 0.90 g / cc to 0.98 g / cc and a melt index of 0.1 g / 10 min to 3.0 g / 10 min.

상기에 있어서, 눈꼽방지제, 산화방지제, 탈크, 대전방지제, 착색제가 각각 1 중량% 내지 10 중량%로 첨가되는 것이 바람직하다.
상기의 눈꼽방지제란 불소계통의 엘라스토마(Elastomer)로서 합성수지의 용융 가공도중에 발생하는 시트 눈꼽(저분자 물질)에 의해 발생하는 얼룩을 방지하기 위해 사용하는 것을 말한다. In the above, it is preferable that a blinding agent, an antioxidant, talc, an antistatic agent, and a coloring agent are added at 1 wt% to 10 wt%, respectively.
The anti-noxious agent is a fluorine-based elastomer (Elastomer) used to prevent stains caused by the nox of sheets (low molecular weight) generated during melt processing of synthetic resins.

이하, 본 발명의 바람직한 일실시예를 첨부도면을 참조하여 상세히 설명하면 다음과 같다.Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

본 실시예의 인테리어 시트용 폴리올레핀 수지조성물은 폴리플로필렌(PolyPropylene : PP), 고밀도 폴리에틸렌(High Density PolyEthylene : HDPE), 저밀도 폴리에틸렌(Low Density PolyEthylene : LDPE), 선형저밀도 폴리에틸렌(Linear Low Density PolyEthylene : LLDPE), 에틸렌 초산 비닐 공중합체(Ethylene Vinyl Acetate : EVA)를 포함하여 이루어진다.Polyolefin resin composition for the interior sheet of the present embodiment is polypropylene (PP), high density polyethylene (High Density PolyEthylene: HDPE), low density polyethylene (LDPE), linear low density polyethylene (Linear Low Density PolyEthylene: LLDPE) And ethylene vinyl acetate copolymer (Ethylene Vinyl Acetate: EVA).

폴리플로필렌, 고밀도 폴리에틸렌, 저밀도 폴리에틸렌, 선형저밀도 폴리에틸렌, 에틸렌 초산 비닐 공중합체는 각각 0.90 g/cc 내지 0.98 g/cc의 밀도와 0.1 g/10min 내지 3.0 g/10min의 용융지수를 가진다. Polypropylene, high density polyethylene, low density polyethylene, linear low density polyethylene, ethylene vinyl acetate copolymers each have a density of 0.90 g / cc to 0.98 g / cc and a melt index of 0.1 g / 10 min to 3.0 g / 10 min.

상기에서, 첨가제로 눈꼽방지제(엘라스토마(Elastomer)), 산화방지제, 탈크, 대전방지제, 착색제가 각각 1 중량% 내지 10 중량%로 첨가되는 것이 바람직하다.In the above, it is preferable that an additive (Elastomer), an antioxidant, talc, an antistatic agent, and a coloring agent are added in an amount of 1 wt% to 10 wt%, respectively.

산화방지제(antioxidant)란 특정 식품, 천연·합성 고무, 가솔린 등의 물질에 첨가하여 실온에서 공기 중에 있는 산소와 이들 물질이 결합하는 과정인 자동산화를 억제하기 위해 첨가하는 화합물이다.Antioxidants are compounds that are added to certain foods, natural and synthetic rubbers, gasoline, etc. to inhibit the automatic oxidation, the process of combining these substances with oxygen in the air at room temperature.

탈크(Talc)는 활석이라고도 하며, 공업용과 의료용 등으로 사용된다. 통상 무색이나 회색으로 분말 가루 형태이며, 화학식은 Mg3H2(SiO3)4 이고, 고무용, 의약용, 고무약품, 도금, 살충제, 난연제, 충전재 등에 주로 사용된다.Talc, also known as talc, is used for industrial and medical purposes. It is usually colorless or gray in powder form, and the chemical formula is Mg 3 H 2 (SiO 3 ) 4 and is mainly used for rubber, medicine, rubber chemicals, plating, insecticides, flame retardants, fillers, and the like.

대전방지제(Antistatic Agents)는 플라스틱에 첨가되거나 완성된 제품의 표면에 처리하여 제품의 표면에 형성되는 정전기를 감소시키거나 제거하는 작용을 하는 첨가제이다. 정전기는 생산성을 감소시키거나 화재, 감전 및 먼지 흡착의 주요 원인이 된다. 이와 같은 정전기에 의한 대전성을 개량하기 위해서는 표면을 화학적으로 처리함으로써 친수성을 도입하는 방법, 친수성의 모노머를 그라프트시키는 방법, 금속분말과 같은 양도체의 물질을 첨가하는 방법 등이 있으나 사용상의 제약과 생산성의 문제로 인해 가장 일반적으로 사용되는 방법은 대전방지제를 첨가하는 방 법이다. 종래 통상적으로 사용되는 대전방지제는 4급 암모늄화합물, 에폭시화아민, 지방산에스테르, 황산화된 왁스 등이다.Antistatic Agents are additives that are added to plastics or treated on the surface of the finished product to reduce or eliminate the static electricity formed on the surface of the product. Static electricity reduces productivity or is a major cause of fire, electric shock and dust absorption. In order to improve the chargeability by static electricity, there is a method of introducing hydrophilicity by chemically treating the surface, a method of grafting hydrophilic monomers, and a method of adding a good substance such as metal powder. Due to productivity problems, the most commonly used method is the addition of antistatic agents. Conventionally used antistatic agents are quaternary ammonium compounds, epoxidized amines, fatty acid esters, sulfated waxes and the like.

플라스틱은 일반적으로 원료수지가 무색투명하고 그 배합이 용이하므로 착색제(Colorant)의 배합에 의해 착색되고 있으며, 사용되는 착색제는 기본적으로 안료와 염료이다. 안료는 물, 용매, 플라스틱에 녹지 않는 착색제의 총칭이며, 염료는 반대로 녹는 착색제의 총칭이다. 또한 이들의 물성차이는 안료가 염료에 비해 착색력, 분산성, 선명성 등이 부족한 반면 내열성, 내후성, 내열제성, 내약품성이 우수하다. 안료는 화학성분에 따라 백색안료, 흑색안료, 무기안료, 유기안료 등으로 나눈다.Plastics are generally colored by colorant blending because the raw material resin is colorless and transparent and easy to mix, and the colorants used are basically pigments and dyes. Pigment is a generic term for colorants which are insoluble in water, solvents and plastics, and dye is a generic term for colorants which dissolve in reverse. In addition, the difference in physical properties of the pigments are excellent in heat resistance, weather resistance, heat resistance, chemical resistance, while the pigment lacks colorability, dispersibility, sharpness and the like. Pigments are divided into white pigments, black pigments, inorganic pigments, and organic pigments according to chemical composition.

착색제는 사용에 따라 건조 착색, 압출 착색, 전체혼합, 액체 플라스틱·액상수지에 착색제를 분산시키거나 용해시켜 섞는 방법으로 착색한다. 염료는 안료와는 달리 일반적으로 사용되는 제품에 용해된다. 따라서 용해성 때문에 유기 또는 무기 어느 것보다도 투명한 대신 고농도로 사용해야 한다. 그리고 염료는 안료보다 비싸고 열에도 약하기 때문에 염료 그 자체를 플라스틱에 사용하지 못하고 불용성 무기 화합물에 침전시켜 불용성으로 만든 color lakes를 사용한다.The colorant is colored by dry coloring, extrusion coloring, total mixing, dispersing or dissolving the colorant in liquid plastic and liquid resin, depending on use. Dyestuffs, unlike pigments, dissolve in commonly used products. Therefore, due to their solubility, they should be used in higher concentrations than transparent, either organic or inorganic. And because dyes are more expensive than pigments and less resistant to heat, they use color lakes that are insoluble in the insoluble inorganic compounds rather than the dyes themselves in plastics.
