PVC塑料鞋及鞋底配方参考(国外英文资料)With PVC as the material with a plastic sandals, shoes, boots, high drum miner slippers and shoes, due to the progress and development of the limitations of the PVC material and shoemaking technology, PVC kind of shoe products increasingly reduced, more and SBS polyurethane elastomer material replaced. But the current domestic market still has some PVC shoes, and some also on the performance of PVC was modified. Here the products are briefly introduced in the paper. A formula, design points of PVC shoe products have two kinds of foaming and non foaming molding, injection molding and two kinds of different processing styles, but the main design principles are basically the same formula. 1, PVC resin: SG-2, 3 types of resin based, also using SG-4, type 5, which mainly depends on the requirements of shoes product performance. General requirements for PVC resin index, apparent density smaller, plasticizer absorption is higher, less uniform particle size of fisheye. 2, plasticizer: the adding amount is large, generally in 60~80PHR, mainly DOP and DBP, accompanied by the appropriate DOS cold-resistance plasticizer and cheap epoxy ester and chlorinated paraffin etc.. Sometimes according to need, also using epoxy soybean oil, citric acid and other environmentally friendly plasticizer. 3, stabilizer: opaque products mainly lead salt stabilizers, or three salt, two salt and metal soap. More transparent products with organic tin and zinc calcium based compound stabilizer. According to variety, there is a big difference between the amount of. 4, stearic acid and paraffin lubricant: mainly, also can use polyethylene wax or oxidized polyethylene wax.5, foaming agent for foaming products, foaming agent is essential. The foaming agent used is two azo formamide (AC foaming agent), injection molding foaming products adding amount of 0.5~1.0PHR, the foaming products for 5~6PHR. 6, pearl pigment: pearl pearl pigment need to add sandals in the formula.
