Aqueous metal anticorrosive, rustproof and thermal insulation coating

Abstract

The invention discloses an aqueous metal anticorrosive, rustproof and thermal insulation coating, which is prepared from the following raw materials: nanometer tungsten trioxide dispersion, ammonium carbonate, hollow glass microbeads, a silicone defoaming agent, iron oxide red, zinc phosphate , aluminum tripolyphosphate, silicon benzene emulsion, aluminum tripolyphosphate, mica powder, titanium dioxide, talc, an anionic wetting agent, a dispersant, a film forming aid, a thickener, an antifreeze agent, deionized water, a coupling agent, an anti-settling agent and a nonionic hydrophobically modified polyurethane block copolymer. The coating disclosed by the invention not only has good salt water resistance, acid resistance, alkali resistance, neutral salt spray resistance and high adhesion,but also has the advantages of good reflectivity, heat insulation, environmental protection, decoration, corrosion resistance and rust resistance properties.

Description

technical field

[0001] The invention relates to a water-based metal anti-corrosion, anti-rust and heat-insulating paint. Background technique

[0002] "Heat insulation coating": refers to a functional water-based coating developed in recent years that blocks, reflects, and radiates near-infrared heat from sunlight, which can insulate and cool roofs, save energy and reduce consumption. It has the characteristics of heat insulation, waterproof, anti-rust, anti-corrosion, short construction period, and quick results. It completely replaces the water spray system, thermal insulation cotton, foam sponge, interlayer iron sheet, etc. There are three main classifications of thermal insulation coatings in terms of characteristics and principles, insulating conductive thermal insulation coatings, reflective thermal insulation coatings and radiation thermal insulation coatings. In addition to the above three types of thermal insulation coatings, a thermal insulation coating has appear...
