【摘要】 用含乙烯基的硅氧烷单体和八甲基环四硅氧烷与丙烯酸酯共聚,制备出不同硅含量的硅丙乳液,研究了有机硅含量对微乳液聚合过程和乳胶膜透明性、交联度、热性能和力学性能的影响。结果表明,随着硅含量的增加,综合性能均得到改善,当有机硅单体用量达20%时为最佳配比。更多还原

【Abstract】 The elastic silicone-acrylate emulsions of different silicone content were prepared using vinyl siloxanes and grafting siloxanes.The effects of silicone content on the process of microemulsion polymerization and transparence,cross-linking degree,heat resistance and the mechanical properties of latex film were studied.The results show that the general performances of silicone-acrylate latex film are improved with the increase of silicone content in monomers,and the latex film has excellent performance when the silicone content gets to 20% of total monomers.更多还原
