Abstract

The invention provides a water-based rust-conversion type thermal insulation coating with high corrosion resistance. The thermal insulation coating is prepared from raw materials in parts by weight asfollows: 5-30 parts of vinyl chloride emulsion, 25-50 parts of a G-OAL cheating type rust conversion agent, 6-12 parts of hollow glass beads, 12-25 parts of nanometer TiO2, 10-20 parts of sericite, 8-12 parts of titanium dioxide, 10-20 parts of talcum powder, 2-10 parts of aluminium triphosphate, 0.9-1.5 parts of a dispersing agent, 0.1-0.3 parts of a wetting agent, 0.3-0.8 parts of a defoaming agent, 3.0-6.0 parts of a coalescing agent, 1.5-3.5 parts of a thickening agent, 1-3 parts of a PH value regulator and 20-50 parts of deionized water. The invention further provides a preparation method of the water-based rust-conversion type thermal insulation coating with high corrosion resistance. The water-based rust-conversion type thermal insulation coating with high corrosion resistance hasthe advantages of being good in rusted construction performance and rust conversion capacity, high in film adhesion, good in corrosion resistance, stable in thermal insulation performance, high in reflection barrier property, good in economic benefit, environmentally friendly, healthy, pollution-free and the like.

Description

technical field [0001] The invention relates to a heat-insulating paint, in particular to a high-corrosion-resistant water-based rust-transforming heat-insulating paint and a preparation method thereof. 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 the sun to insulate and cool the roof, save energy and reduce consumption. It has heat insulation, waterproof, antirust, anticorrosion , short construction period and quick effect, fully replace the water spray system, thermal insulation cotton, foam sponge, interlayer iron sheet, etc. There are three main types of thermal insulation coatings in terms of characteristics and principles, insulating conductive thermal insulation coatings, reflective thermal insulation coatings and radiant heat insulation coatings. In addition to the above three types of heat insulation coatings, a heat insulation...
