一种用做混凝土表面防护的有机蒙脱土改性弹性涂料及其制备方法
摘要：
本发明提供了一种用做混凝土表面防护的有机蒙脱土改性弹性涂料及其制备方法。所述有机蒙脱土改性弹性涂料中20～40%的有机蒙脱土改性核壳丙烯酸乳液，25～35%颜填料，0.01～0.1% PH调节剂，0.1～1.0%的交联剂，0.3～1％的分散剂，0～1%成膜助剂，0.3～1%防冻剂，0.3～1％的消泡剂，0.3～1%增稠剂，0.1～0.2%杀菌剂，余量的水。目前的弹性涂料主要着重于解决弹性涂料的耐沾污性，而对抗碳化和耐老化方面很少涉及。本发明具丙烯酸弹性涂料的弹性抗裂性能，同时具备抗回粘、耐玷污、抗碳化、耐老化等特点。
摘要（英）：

The invention provides organic montmorillonoid modified elastic paint for protecting concrete surface and a preparation method thereof. The organic montmorillonoid modified elastic paint comprises 20-40% of organic montmorillonoid modified core-shell acrylic emulsion, 25-35% of pigment filler, 0.01-0.1% of PH regulator, 0.1-1.0% of cross-linking agent, 0.3-1% of dispersant, 0-1% of film forming auxiliary, 0.3-1% of antifreezing agent, 0.3-1% of defoamer, 0.3-1% of thickener, 0.1-0.2% of bactericide and the balance of water. Current elastic paint puts main emphasis on stain resistance of the elastic paint, and seldom relates to the aspects of carbonization resistance and aging resistance. The acrylic acid elastic paint has elastic crack resistance and has the advantages of being resistant to after-tack, stain, carbonization and aging.
