摘　　要：以氯硅烷与烷氧基硅烷为原料,制备了含有支链结构的新型有机化合物——γ-甲基丙烯酰氧基丙基三(三甲基硅氧基)硅烷(MATS),将MATS、硅烷偶联剂A-174、丙烯酸酯类单体反应制备了硅改性聚丙烯酸酯乳液,并在玻璃纤维网布上进行了性能实验。结果表明:该薄膜的柔性较好、不粘连、强度高、耐碱保留率达80%以上;有机硅化合物与丙烯酸酯类单体发生了共聚;制备的硅改性聚丙烯酸酯具有典型的核壳结构。Chlorosilane and alkoxysilane were used to prepare a novel organic compound,γ-methyl acryloyloxypropyl tri(trimethylsiloxy)silane with branched structure,which was reacted with silane coupling agent A-174 and acrylate monomers to obtain silicon modified polyacrylate emulsion.The properties of the product were tested on the glass mesh.The results show that the flexibility of film is good,which has no adhesion and performs high strength,whose alkali retention rate is over 80%.Silicone copolymer is copolymerized with acrylate monomers.The modified poly acrylate has a typical core-shell structure.
