Elastic wind sand/wear and corrosion/weather/temperature change resistant paint and preparation method thereof

Abstract

The invention discloses an elastic wind sand / wear and corrosion / weather / temperature change resistant paint. The paint comprises a component A and a component B, wherein the component A comprises 20.0-31.8 of elastic polyester resin, 15.0-20.0 of epoxy-organic silicone modified fluorocarbon resin, 30.0-33.0 of mixed solvent, 0.3-1.0 of wetting and dispersing agent, 0.1-0.5 of defoaming agent, 0.1-0.5 of thixotropic agent, 0.3-1.0 of ultraviolet complex stabilizer and 18.0-25.0 of nano slurry; and the component B comprises 5-10 of HDI (hexamethylenene diisocyanate) biuret and 90-95 of HDI tripolymer. The paint has the following advantages: the ultraviolet shielding rate of the paint can be more than 95%; the paint has excellent elasticity, wear resistance and recovery rate and can resist wind sand impact and high / low temperature deformation for a long time, and lives of the materials can reach 20 years after one-time coating; the paint has excellent self-cleaning and stain resisting functions; and the paint is convenient in construction and the one-time construction thickness can reach 150mu m.

Description

technical field [0001] The invention relates to an anti-corrosion coating technology, in particular to an elastic wind-sand, abrasion-resistant, weather-resistant and temperature-resistant coating and a preparation method thereof. Background technique [0002] Implementing the western development strategy and accelerating the economic development of the central and western regions is a major decision of our country to look far ahead, take the overall situation into consideration, and face the new century. It is a large-scale systematic project, and materials are the backbone of infrastructure construction and economic development in the central and western regions. and important foundations. Most of the central and western regions are dry and rainless areas (annual precipitation is below 150ml), strong and frequent sandstorms, strong ultraviolet radiation (more than 30% stronger than plain areas), and large temperature differences between day and night (-30°C to 60°C).
