碳纳米管改性无机-有机水性富锌涂料的制备及其性能
Fabrication and Performance of Inorganic-Organic Zinc-Rich Paints Modified by Carbon Nanotubes
摘 要
在常见的水性无机硅酸盐富锌涂料中添加适量的硅丙乳液及碳纳米管,制成了无机-有机复合水性富锌涂料.对几种不同配比涂层的主要力学性能、电化学性能、耐盐雾性能及耐空蚀性能进行了测试分析,结果表明当硅丙乳液和碳纳米管分别占基料的20%和1%,颜基比为2:1时,涂料的基料稳定,喷涂粘度适中:同时涂层在保持了无机富锌涂料优异耐腐蚀性能的基础上,其耐空蚀性能也得到了很大提高.

Abstract
Inorganic-organic composite zinc-rich paints were produced by adding organic filming material (silicone acrylic emulsion) and carbon nanotubes to conventional water borne inorganic zinc-rich paints.The effects of silicone acrylic emulsion and carbon nanotubes on the mechanical properties,anticorrosion and anticavitation behaviors of the inorganic-organic zinc-rich coatings were investigated.The results showed that the liquid component of the paints was homogeneous and the viscosity was suitable when the concentrations of silicone acrylic emulsion and carbon nanotubes were around 20 wt% and 1 wt% respectively,the ratio of pigments / binder was 2/1.The corrosion resistance and cavitation resistance of the corresponding coating were remarkablely improved.
