A process for continuously manufacturing, under ordinary pressure, heat-resistant crosslinked vinyl chloride resin foam having a low density and uniform, fine cells, which process comprises a first step of gelling a mixture of vinyl chloride resin, plasticizer, stabilizer, crosslinking aid, and blowing agent under such conditions that the blowing agent is not decomposed, and then molding the thus gelled mixture into a desired shape; a second step of crosslinking the resulting molding by irradiation with an ionizing radiation; and a third step of heating the thus corsslinked product to expand it.
一种在普通压力下连续制造具有低密度和均匀细孔的耐热交联氯乙烯树脂泡沫塑料的工艺,该工艺包括:第一步,在发泡剂不分解的条件下,将氯乙烯树脂、增塑剂、稳定剂、交联助剂和发泡剂的混合物胶化,然后将胶化的混合物模塑成所需形状;第二步,用电离辐射辐照交联成型;第三步,加热交联产品使其膨胀。
