摘要
采用适量氟硅酸钠改性剂和有机胺促进剂对基料水玻璃进行改性 ,协调粘性、耐水性和凝胶时间的相互关系 .以磷酸、氧化硅、氧化锌、铝盐、钙盐及钡盐等为原料制备磷硅酸盐固化剂 .用固化剂促进水玻璃的聚合和二氧化硅凝胶的缩合 ,拼用苯丙乳液作为辅助成膜物质 .然后利用正交法优选配方 ,制得耐水性良好、附着力强的水玻璃复合涂料 .它具有成本低廉、不污染环境和耐老化等特点 ,可应用于防火涂料和外墙涂料上 .
Sodium Silicate as base material is modified by using sodium fluorosilicate in appropriate amount and organic amine as modfication accalerator to coordinate the interrelation of viscidity and water tolerance and gelation time. Firming agent is prepared by using phosphoric acid, silicon oxide, zinc oxide, aluminium salt, calcium salt and barium salt as raw materials. The polymerization of sodium silicate and gel condensation of silicon dioxide are accelerated by using the firming agent.Auxiliary film forming matter is made of phenypropyl emulsion. Then the prescription is optimized by orthogonal method.Thus a sodium silicate composite coating with good water tolerance and strong adhesion is prepared. The coating is characterized by cheap in cost, pollution free and aging resistant. It can be applied as fire proofing coating and outer wall coating.
