EFFECT OF BASALT FLAKE ON ADHESION OF COATING
-
摘要: 海洋环境对用于钢结构的防腐涂料性能提出了非常高的要求,尤其是钢与涂料之间的附着力,是涂料发挥防腐作用的基础。以环氧树脂为基料,通过18个试件研究鳞片种类、鳞片含量、鳞片目数、固化剂种类及固化剂比例5个变量对涂料附着力的影响。研究表明:当玄武岩鳞片含量为20%,目数为400目,固化剂为聚酰胺,环氧树脂与聚酰胺比例2:1时,玄武岩鳞片涂料的附着力达到最大。Abstract: The marine environment has very high requirements for the performance of anticorrosive coatings for steel structures, especially the adhesion between steel and coatings, which is the basis of anticorrosive coatings. The influence of flake type, flake content, flake particle size, curing agent type and curing agent proportion on coating adhesion was studied by conducting tests on 18 specimens and using epoxy resin as the substrate. The adhesion of the coating reached the maximum when the basalt flake content was 20%, the particle size was 400, the curing agent was polyamide, and the ratio of epoxy resin to polyamide was 2:1.
