본문에 상술하고 도면에 표시한 바와같이, 초산비닐 함량이 10-40중량%인 에틸렌초산비닐 공중합체 100중량부와 가교제 1∼5중량부, 발포제 20∼80중량부를 혼합하는 제1의 방법과 상기 제1의 방법중에서 발포제를 20∼100중량부로 하고 폴리에틸렌 이나 폴리스틸렌중 적어도 하나를 5∼50중량부 추가하는 제 2의 방법과, 상기 제 1의 방법중에서 발포제를 20∼70중량부로 하고 폴리염화바닐수지 100중량부와 가소제 50∼150중량부, 안정제 3∼8중량부로된 폴리염화비닐수지 페이스트 5∼50중량부를 추가하는 제 3의 방법과 상기 제 1, 제 2, 제 3의 방법에 의하여 혼합된 혼합물을 시이트상으로 성형하여 성형틀내에 충전하고 성형틀을 복개폐쇄시킨 다음, 이를 약 160∼180℃온도로 가열하여 발포체를 성형하고, 이 발포체를 성형틀내에서 가압상태로 한 다음 성형틀내에 보지한채로 약 60∼130℃의 온도로 냉각시킨 다음 성형틀의 복개를 개방하거나 또는 상기 냉각 온도보다 낮은 약 50∼100℃로 냉각하여 발포체를 성형틀로부터 취출한 후, 이를 별도의 금형에 넣어 약 100∼130℃ 온도로 재차 가열한 후 금형으로부터 추출하여 밀도 0.1이하의 합성수지발포체를 제조함을 특징으로 하는 저밀도 합성수지 발포체와 그 제조 방법.As described above and shown in the drawings, the first method of mixing 100 parts by weight of ethylene vinyl acetate copolymer having a vinyl acetate content of 10-40% by weight, 1 to 5 parts by weight of a crosslinking agent, and 20 to 80 parts by weight of a blowing agent and In the first method, a second method of adding 20 to 100 parts by weight of a blowing agent and 5 to 50 parts by weight of at least one of polyethylene or polystyrene, and a polychlorinating agent with a blowing agent of 20 to 70 parts by weight in the first method According to the third method and the first, second and third methods of adding 5 to 50 parts by weight of a polyvinyl chloride resin paste comprising 100 parts by weight of a vanyl resin, 50 to 150 parts by weight of a plasticizer, and 3 to 8 parts by weight of a stabilizer. The mixed mixture is molded into a sheet, filled into a molding mold, the molding mold is closed and opened, and then it is heated to a temperature of about 160 to 180°C to mold a foam, and the foam is pressurized in the molding mold and then molded. Cooled to a temperature of about 60 to 130° C. while retaining the inside, then opened the abdomen of the molding frame or cooled to about 50 to 100° C. lower than the cooling temperature, and then the foam was taken out from the molding frame, and then it was placed in a separate mold. Put it and heat it again to a temperature of about 100~130℃ and extract it from a mold to produce a synthetic resin foam having a density of 0.1 or less and a method for manufacturing the same. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: Disclosure is based on the original application.
