摘要
研究了发泡剂、交联剂、弹性体、不同种发泡促进剂的用量对EVA(乙烯 /醋酸乙烯共聚物 )材料性能的影响 ,考察了发泡成型工艺对材料性能的影响。试验结果表明 ,配方组成与成型工艺对材料发泡效果及制品性能有密切关系 ,确定了稳定、可靠的生产配方和工艺控制条件。配方为发泡剂 0 .5 5 % (质量分数 ,下同 ) ,促进剂A 0 .5 0 % ,B 0 .5 0 % ,C 0 80 % ,交联剂 0 0 7% ,弹性体 10 % ,填充剂 10 %。工艺条件为塑化温度 190～ 2 0 0℃ ,模具温度 5 0～ 60℃。
The influence of consumption of the blowing agent,cross-linking agent ,elastomer and bubble promo- ter on EVA material properties was studied.The influence of foaming conditions on the material properties was investigated. The results indicated that the foaming effect and products properties have close relation with the formula and shaping technology .A stable,reliable formula and technology had been determined. The optimum formula was blowing agent 0.55%(mass ratio),bubble promoter A 0.50%,B 0.50%,C 0.80%,cross-linking agent 0.07%, elastomer 10%,filler 10%. The temperature of plasticizing and the mould were respectively 190～200 ℃,50～60 ℃。
