一种水性聚氨酯防潮防腐涂料及其制备方法
摘要：
一种水性聚氨酯防潮防腐涂料及其制备方法，该涂料包括改性聚氨酯复合乳液、填料、羟乙基纤维素、防腐剂、甲基硅油、邻苯二甲酸二丁酯、锆‑铝酸酯类偶联剂、颜料、变定剂、丙烯酸酯溶液、分散剂、助剂和水，其制备方法：将水、分散剂、颜料、填料、锆‑铝酸酯类偶联剂、甲基硅油搅拌均匀后用砂磨机分散61‑70min，制得颜填料浆；在容器中加入改性聚氨酯复合乳液，搅拌下加入颜填料浆、防腐剂、聚丙烯酸酯溶液、助剂，搅拌速度为410‑450r／min，搅拌时间为21‑30min，其中在5‑10min时，加入羟乙基纤维素；最后，用160目的绢布滤网过滤得到的滤液与5‑7份变定剂混合搅拌，即得本发明产品。本发明具有耐化学性强、耐水、防潮效果好、光泽度高、涂膜寿命长等特点。
摘要（英）：

The invention discloses waterborne polyurethane dampproof anticorrosive coating and a preparation method thereof. The waterborne polyurethane dampproof anticorrosive coating comprises modified polyurethane composite emulsion, packing, hydroxyethyl cellulose, a preservative, methylsilicone oil, phthalic acid dibutyl ester, a zirconium-aluminic acid ester coupling agent, pigment, a hardening agent, an acrylic ester solution, a dispersing agent, additives and water. The preparation method comprises the following steps: uniformly stirring the water, dispersing agent, pigment, packing, zirconium-aluminic acid ester coupling agent and methylsilicone oil, and dispersing for 61-70 minutes by using a sand mill so as to prepare pigment packing slurry; adding the modified polyurethane composite emulsion into a container, adding the pigment packing slurry, the preservative, the acrylic ester solution and the additives when stirring for 21-30 minutes at the stirring speed of 410-450r/minute, and after stirring for 5-10 minutes, adding hydroxyethyl cellulose; finally, filtering by using a silk filtering net of 160 meshes, and mixing and stirring the obtained filtrate with 5-7 parts of the hardening agent, thereby obtaining the waterborne polyurethane dampproof anticorrosive coating. The waterborne polyurethane dampproof anticorrosive coating has the characteristics of good chemical resistance, good water resistance, good damproof effect, high glossiness, long film service life and the like.
