高级胶清与新鲜胶乳并用制备复合橡胶的研究

胶清经中空纤维柱过滤浓缩后，与木瓜蛋白酶反应制备高级胶清，将高级胶清与新鲜胶乳按一定干基质量比混合、共凝制备复合橡胶，研究高级胶清与新鲜胶乳并用比对复合橡胶性能的影响。结果表明：当高级胶清用量为10～40份时，复合橡胶的理化性质可达到国产5^#标准胶的要求；高级胶清能促进复合橡胶的硫化并提高其物理性能。;The natural rubber skim latex was filtered and concentrated in hollow fiber column，and reacted with papain to form high-performance skim.The compound rubber was then prepared by co-agglomeration of the blend of high-performance skim and fresh natural rubber latex.The effect of blending ratio of skim and natural rubber latex on the properties of compound rubber was investigated.The results showed that addition of high-performance skim could promote vulcanization of the compound rubber and improve its physical properties.When the addition level of high performance skim was 10～40 phr，the physico-chemical properties of compound rubber met the requirements of SCR 5#
