以环氧树脂和有机硅树脂混合物为主要成膜物质,使用低毒环保型溶剂,同时填充纳米级气相硅微粉,制备了一种溶剂型环保防潮助剂。 使用该助剂进行涂覆后,瓦楞纸板的表面接触角最高可达 172. 4°。 试验确定的最佳工艺配方(质量分数),环氧树脂为 16% ,固化剂为 7% ,有机硅树脂为 4% ,气相二氧化硅为 6% ,碳酸二甲酯为 60% ,丙二醇丙醚醋酸酰胺酯为 7% 。

The solvent based environmental friendly water-repellent reagent was prepared using epoxy and silicone resin as main filming material, low-toxic solvent as solvent, and nano-silica powders as filling. The water contact angle the paperboard coated with water-repellent reagent was up to 172. 4°. The optimum formula determined is epoxy resin (16% ), curing agent (7% ), silicone resin (6% ), silica powder (6% ), Dimethyl carbonate (60% ), and CBC (7% ).
