Abstract

자동차용으로 사용되고 있는 기본 보조매트는 포리염화비닐(PVC), 고무로 되어있어 포리염화비닐(PVC)는 유독한 가스가 발생되어 자연환경문제로 자동차회사 및 서유럽에서는 규제대상으로 되고 있으며, 고무는 가격면에서도 비싸며 고무특유의 냄새가 발생되고 대량생산에는 한계가 있고 PVC, 고무는 겨울철에는 딱딱하다는 단점이 있다.The basic auxiliary mats used for automobiles are made of polyvinyl chloride (PVC) and rubber. Polyvinyl chloride (PVC) is a regulated product in automobile companies and Western Europe due to natural environmental problems due to the generation of toxic gases. It is expensive in terms of price, has a peculiar smell of rubber, has a limitation in mass production, and PVC and rubber are hard in winter.

[발명의 명칭][Name of invention]

자동차바닥 매트제조용 쉬이트 조성물Sheet composition for automobile floor mat manufacturing

[발명의 상세한 설명]Detailed description of the invention

[발명의 목적][Purpose of invention]

[발명이 속하는 기술분야 및 그 분야의 종래기술][Technical field to which the invention belongs and the prior art in that field]

본 발명품은 자동차 내부의 바닥에 발판으로 이용되는 쉬이트제조용 조성물에 관한 것이다.The present invention relates to a sheet manufacturing composition to be used as a scaffold on the floor of the vehicle interior.

자동차용 바닥매트의 쉬이트는 종래에는 고무, 폴리염화비닐로 구성되어 사용하였으나 폴리염화비닐은 유독한 가스와 냄새가 발생되고 중량이 무겁고 겨울철에는 딱딱하며 고무는 가격이 비싸며 고무특유의 이취발생으로 사용성이 떨어지며, 압출성형에 제한이 있어 경제성이 없고 내열성이 약하며 가공성이 떨어진다.Sheets of automobile floor mats were conventionally composed of rubber and polyvinyl chloride. However, polyvinyl chloride generates toxic gases and odors, is heavy in weight, hard in winter, and rubber is expensive. Is low, there is a limit to the extrusion, economical, heat resistance is weak and workability is poor.

한국특허공고 90-9341호는 금형면 상에 50-150μ입도의 고무분을 압력으로 프레스하여 자동차용 보조매트의 제조방법을 사용하였으나 이는 경제성이 없고 고무제품은 특히 냄새가 심하며 바닥면에 미끄러지는 현상이 발생됨은 물론 생산가가 비싸고 겨울철에는 경화되어 파손이 쉽게 되는 단점이 있다.Korean Patent Publication No. 90-9341 used a method of manufacturing an auxiliary mat for automobiles by pressing a 50-150μ particle size rubber powder on a mold surface. As well as the phenomenon occurs, the production price is expensive and there is a disadvantage that the hardening in the winter is easy to break.

[발명이 이루고자 하는 기술적 과제][Technical problem to be achieved]

본 발명품은 우수한 유연성을 갖으면서도 고무의 특유한 냄새도 없애고 폴리염화비닐에서 발생되는 유독한 가스발생도 없애며 신장율이 높고 가공성이 좋은 동시에 자동차에서 요구되는 내열성도 우수하고 내수성 뛰어난 내구성, 경량성도 우수한 자동차용매트 쉬이트 조성물을 제공하며 현 자동차 회사에서 폴리염화비닐 규제에 따른 새로운 쉬이트 조성물과 그 제조방법인 것으로서 고무제품인 자동차용 매트 보다 생산성이 월등히 우수하며 코스트다운으로 경제성을 일층 고양시키는 것으로 그 제조방법을 제공하고자 한다.The present invention has excellent flexibility and eliminates the peculiar smell of rubber, eliminates the toxic gas generated from polyvinyl chloride, has high elongation rate and good processability, and has excellent heat resistance required in automobiles, excellent water resistance, durability and light weight. It provides a mat sheet composition and is a new sheet composition according to the polyvinyl chloride regulation in the current automobile company and its manufacturing method, which is far more productive than rubber mats for rubber products and improves economics with cost down. To provide.

특히, 에틸렌과 올레핀을 공중합시킨 코폴리머 수지를 사용하여 고무 및 폴리염화비닐의 냄새를 없애고 동절기에도 탄성을 그대로 유지하며, 자동차바닥과의 접착성을 향상시켜 매트가 미끄러지는 현상을 방지하며 산화방지제 및 자외선 방지제, 난연제등 첨가제를 첨가하지 않고도 고무와 같은 기능을 발휘할 수 있는 우수한 자동차용 매트 쉬이트 조성물을 제공하고자 한다.In particular, the copolymer resin of ethylene and olefin is used to eliminate the odor of rubber and polyvinyl chloride, maintain elasticity even in winter, and improve the adhesiveness to the car floor to prevent the mat from slipping and to prevent antioxidants. And to provide an excellent automotive mat sheet composition that can exhibit a rubber-like function without adding an additive such as a sunscreen, flame retardant.
