一种新型水性环保防锈涂料的研制

Study of a New Waterborne Antirust Coating

以苯乙烯和丙烯酸丁酯作为主要单体,甲基丙烯酸及甲基丙烯酸甲酯作为必要成分,采用过硫酸盐作引发剂,在乳化剂作用下进行聚合制得苯丙乳液。通过正交实验和综合评分的方法,研究了多元苯丙乳液体系的聚合方式、共聚单体、软/硬单体配比、乳化剂用量、引发剂用量和聚合温度对乳液性能的影响,确定了制备苯丙乳液的最佳工艺参数,由其配制的水性防锈涂料性能优良。

To meet the needs of environmental protection and marketing, a new waterborne antirust coating was developed. Emulsion is prepared by emulsified polymerization, in which styrene and n-Butyl acrylate were used as the main monomers, methacrylic acid and methyl methacrylate were used as necessary components, ammonium persulfate used as initiator. By means of orthogonal testing and overall merit assessment, the influence of polymerization process of the multiple styrene/acrylic emulsion system, monomers for copoly merization, ratio of hard/soft and temperature of reaction on the emulsion properties were studied. The optimum emulsion polymerization technology parameters were determined, which can formulate a waterborne antirust coating with excellent properties.
