| 摘 要： | 针对岩棉对水敏感的弱点,重点研究具有良好防水功能的岩棉外保温系统抹面砂浆,对比了EVA乳胶粉和丙烯酸乳胶粉与有机硅憎水剂在抹面砂浆中复合使用情况,研究结果表明,丙烯酸乳胶粉的防水性更为优异,丙烯酸乳胶粉7042W掺量2.5％时可以使5mm抹面砂浆不透水,EVA乳胶粉6022E和有机硅憎水剂复合使用也可以达到相同效果；在热老化作用下,抹面砂浆的吸水量有所增加,抗冲击强度有所下降,丙烯酸乳胶粉7042W的耐热老化性能明显优于EVA乳胶粉6022E.

| Abstract: | Aiming at the water-sensitive weakness of rock wool,surface mortar for rock wool-based ETICS with good waterproof performance was particularly researched.The compound use condition of EVA emulsion powder,acrylic latex powder with silicone water repellent in surface mortar was compared.The research results showed that the waterproof performance of acrylic latex powder was better,5 mm surface mortar can be impermeable when the content of acrylic latex powder 7042W was 2.5%,and compound use of EVA emulsion pow... |
