Anti-adhesion rock slice and preparation method thereof
The invention discloses an anti-adhesion rock slice, which is prepared from the following components in percentage by weight: 30 to 50 parts of waterborne acrylic resin, 5 to 20 parts of chitin, 0.1 to 2 parts of mixed acid, 0.05 to 1 part of accelerant, 15 to 45 parts of filler and the balance of water, wherein the mixed acid comprises boric acid and at least one organic acid, the molar ratio of the boric acid to the organic acid is (1: 10)-(10: 1), the deacetylation degree of the chitin is lower than 50%, and the water-based acrylate is selected from one or more of hydroxyethyl acrylate, hydroxypropyl acrylate and glycidyl methacrylate. The rock slice can be mixed, stirred and dispersed in natural colored sand or sintered colored sand, can also be prevented from being ground, and after being stored at high temperature and high humidity, the rock slice can keep stable quality, the flexibility is not obviously changed, adhesion is avoided, and the rock slice has excellent anti-adhesion performance.
本发明公开一种抗粘连的岩片，包括按重量百分比的如下组分：水性丙烯酸树脂30份～50份、甲壳素5份～20份，混合酸0.1份～2份，促进剂0.05份～1份，填料15～45份，水补足至100份；其中，所述混合酸包含硼酸和至少一种有机酸，所述硼酸与所述有机酸的摩尔比值为1:10～10:1，所述甲壳素的脱乙酰度低于50%，所述水性丙烯酸酯选自丙烯酸羟基乙酯、丙烯酸羟丙酯和甲基丙烯酸缩水甘油酯中的一种或多种。本发明的岩片，既能在天然彩砂或烧结彩砂混合搅拌分散开，还能防止被磨碎，在经过高温高湿存贮后，本发明的岩片也能保持质量稳定，柔韧性不发生明显的变化，不粘接，具有优异的抗粘连性能。
