一种硅氧烷基甲基丙烯酸酯及共聚物乳液的制备与应用
Preparation and application of siloxyl methacrylate and its copolymer emulsion
摘要
Abstract
A novel siloxyl methacrylate monomer of γ- [1,1,3,3,5,5,5- heptamethyl- tris(siloxyl)]propyl meth⁃acrylate was synthesized, using 1,1,3,3- tetramethyldisiloxane, al yl methacrylate and trimethyl chlorosilane as raw materials. Then it was applied in emulsion copolymerization to obtain corresponding siloxyl methacrylates copolymer emulsion finishing agent, which was employed in cotton fabric. The influences of monomer dosage on particle size, Zeta potential, thermal stability of emulsion film and water repel ency of the finished fabric were discussed. When the mole ratio of synthesized siloxyl methacrylate monomer and MMA was 2∶1, the re⁃action temperature was 70 ℃, and the reaction time was 3 h, the obtained emulsion particle size was 251.7 nm, Zeta potential was- 48.6 mV, the temperature of emulsion film losing 5% of weight was 217 ℃, and the contact angle of finished cotton fabric reached 129.4°. The results indicated that the novel siloxyl methacrylate finished fabric had good water repel ency and the thermal stability was greatly improved.关键词
