【摘要】：采用預乳化半連續(xù)種子乳液聚合方法合成了GPES保溫板專用界面劑有機硅改性丙烯酸乳液。通過引入丙烯酸異辛酯(2-EHA)、甲基丙烯酸甲酯(MMA)、苯乙烯(St)和功能性單體丙烯酸(AA)和硅烷偶聯(lián)劑(A-174、A-151),提高GPES保溫板的粘結(jié)強度。研究了軟硬單體比例、丙烯酸用量、硅烷偶聯(lián)劑用量及配比對粘結(jié)強度的影響。測試結(jié)果表明,合成的專用界面劑能顯著提高GPES保溫板與砂漿的拉伸粘結(jié)強度。
[Abstract]:Silicone modified acrylic emulsion, a special interface agent for GPES insulation plate, was synthesized by pre-emulsification semi-continuous seed emulsion polymerization. The bond strength of GPES insulation plate was improved by introducing isooctyl acrylic acid (2-EHA), methyl methacrylate (MMA), styrene (St) and functional monomers (AA) and Silane coupling agent (A 鈮，
