Abstract

PURPOSE: A synthetic resin for replacing P.V.C. and styrene is provided to substantially eliminate carbon dioxide with no generation of dioxin and dimer as harmful materials by comprising as a principal resin, the ethylene copolymer and styrene-ethylene-butadiene terpolymer. CONSTITUTION: The synthetic resin composition comprises 75-90% ethylene copolymer (1,2) together with other transparent pigment; 10-25% ethylene terpolymer; 15-30% EPDM terpolymer; 70-85% ethylene copolymer; 0.6-1.2% lubricating agent; about 0.5% filler(3); and 0.8-1.2% stabilizer(5). The resin is prepared by mixing all of the components in a low speed mixer(6) for 5-7 minutes then removing moisture at 40-50 deg.C for 10-15 minutes in a dehydrator(7); placing the mixture into an extruder through a hoper(8) to extrude it up to Shore A 50-95 at the cylinder(11) temperature of 120-145 deg.C for 5-10 minutes. The extruder has a screw(11) length ratio of 32:1 or 34:1. The process has also an air-cooling cutter(12), a cooling pipe(13) and a container such as silo(14) containing the final product.

이와같은 본발명을 더욱상세히 설명하면 다음과같다.The present invention is described in more detail as follows.

본발명에있어서 유색의 합성수지 제조시에는 기초합성수지인 에틸렌 코폴리머를 70%-85%,EPDM 터폴리머를 15%-30%와 충진제0.5%,활제0.6-1.2%,안정제 및 기타첨가제0.8%-1.0%를넣고 투명의 합성수지제조시에는 기초합성수지인 에틸렌 터폴리머를 10%-25%,에틸렌 코폴리머를 75%-90%와 충진제0.5%,활제0.6%-1.2%,안정제 및 기타첨가제를 0.8%-1.0%넣어 저속배합기에서 5분-7분동안 혼합한다음제습기를 통하여 혼합물의 수분을 40℃-50℃상태에서 10분-15분간 제거한다음 호-퍼를 통해 압출기에 넣어 연질과 경질을 표현하고자할 경우 수지의 혼합비율로서 조정하여 SHORE A 50-95 까지 가능하며 압출기조건을 실린더온도 120℃-l45℃에 스크류 의 길이가 32:1,혹은34:1의 비율로서 스크류 중간부분에 압력을 받을수있도록 가공(FLIGHT DEPTH)하여 압출처리 시간 5분-10분 융용혼합하여 토출시킨다.In the present invention, in the production of colored synthetic resin, 70% -85% of the basic synthetic resin, ethylene copolymer, 15% -30% of EPDM terpolymer, 0.5% of filler, 0.6-1.2% of lubricant, 0.8% of stabilizer and other additives In case of adding 1.0% of transparent synthetic resin, 10% -25% of basic synthetic ethylene terpolymer, 75% -90% of ethylene copolymer, 0.5% of filler, 0.6% -1.2% of lubricant, 0.8% of stabilizer and other additives % -1.0% is mixed in a low speed mixer for 5 minutes-7 minutes, and then the moisture of the mixture is removed through a dehumidifier at 40 ° C-50 ° C for 10 minutes-15 minutes, and then put into an extruder through a hopper to give soft and hard materials. If you want to express it, you can adjust it by mixing ratio of resin up to SHORE A 50-95. Extruder condition is cylinder temperature 120 ℃ -l45 ℃ and screw length is 32: 1 or 34: 1. Extrusion process time by 5 minutes-10 minutes The.

이때 압출기의 실린더 내부온도가 200℃정도의 경우까지 고온상태이면 수직의 탄화현상이 오게되고 투명도가 낮아진다.At this time, when the temperature inside the cylinder of the extruder is about 200 ° C., the carbonization is vertical and transparency is lowered.

이와같은 제조공정을 통해 완성되는 본 발명품인 열가소성 합성수지는 기존의 에칠렌제품이 접착성이 전혀 불가능한테 비해 어느정도의 일정한 극성기를 부여하면 높은강도의 접착효과를 얻을 수 있다.The thermoplastic synthetic resin of the present invention, which is completed through such a manufacturing process, can obtain a high strength adhesive effect when a certain polar group is given to a certain degree compared to that of conventional ethylene products.

본 발명품인 P.V.C 및 스티렌대체용합성수지는 기존의 P.V.C가 연소시 배출하는 환경 유해물질인 다이옥신 및 국내산 스티렌연소시 발생하는 다이머 역시 전혀 발생하지않고 이산화탄소의 배출량이 획기적으로 현저히 감소되며 기존의 에틸렌 제품이 접착성이 전혀 없는데 반해 어느 정도의 일정한 극성기를 부여하여 높은강도의 접착성을 얻을 수 있는 큰 장점이있다. 따라서 종전에 사용되던 특수한 전 처리제가 필요 없이 일반적으로 MODIFY된 전처리만 하여도 집착효과를 얻을 수 있고 약품의 비용축면에서도 유리하다. 또한 압출, 사출, BLOW 성형을 이용한 상품성형이 충족되어 그 시장성은 국내 및 해외시장에 막급한 수요를 확신함.PVC and styrene substitute synthetic resin of the present invention is no environmentally harmful dioxin emitted from combustion of conventional PVC and dimers generated from domestic styrene combustion, and carbon dioxide emissions are drastically reduced, and existing ethylene products are significantly reduced. While there is no adhesive at all, there is a big advantage to obtain high strength adhesiveness by giving a certain degree of polarity. Therefore, there is no need for a special pretreatment agent used in the past, and in general, the MODIFY pretreatment alone can obtain the sticking effect and is advantageous in terms of cost reduction of the drug. In addition, as product molding using extrusion, injection, and blow molding is satisfied, its marketability is convinced of urgent demand in domestic and overseas markets.
