一、概述多元醇烷基硅酸醋锌粉涂料(以下简称PSZ涂料)是国外七十年代发明的一种新型长效防腐蚀涂料。由于它对黑色金属具有极好的防蚀性,因此在国外很快得到了充分的重视和迅速的发展。 PSZ涂料是介于有机和无机涂料之间的一种自干型涂料。该涂料的粘结剂合成原理是采用缩聚硅氧烷、烷基硅酸酯或是含有1至6个碳原子的羟烷基、烷氧烷基、羟烷氧
First, an overview of polyalcohol alkyl silicate zinc coating (hereinafter referred to as PSZ coating) is a new long-term anti-corrosion coating invented in the seventies abroad. Due to its excellent corrosion resistance to ferrous metals, it has quickly gained sufficient attention and rapid development abroad. PSZ paint is a self-drying coating between organic and inorganic coatings. The binders for this coating are synthesized using polycondensation silicones, alkyl silicates or hydroxyalkyl groups containing from 1 to 6 carbon atoms, alkoxyalkyl, hydroxyalkoxy
