Abstract

The invention discloses a preparation method of a waterborne epoxy corrosion-resistant heat-insulating coating and belongs to the technical field of building materials. The preparation method comprises the following steps: stirring and mixing nano titanium dioxide, nano antimony tin oxide and deionized water, then adding a wetting agent, a dispersant and a defoamer, and then dropwise adding ammonia water to adjust the pH to obtain a pre-dispersed liquid; frosting the pre-dispersed liquid, ultrasonically dispersing the pre-dispersed liquid, leaving the pre-dispersed liquid to stand, and filtering the pre-dispersed liquid to obtain mixed functional slurry; stirring and mixing 20-30 parts by weight of a waterborne fluorocarbon emulsion, 3-5 parts by weight of a modifying additive, 8-10 partsof unsaturated polyester resin, 2-3 parts of alcohol vinegar 12 and 2-3 parts of a thickener, then adding the mixed functional slurry which is 0.6-0.8 time of the waterborne fluorocarbon emulsion by mass and isocyanate which is 0.02-0.03 time of the waterborne fluorocarbon emulsion by mass, and stirring and mixing the mixture to obtain the waterborne epoxy corrosion-resistant heat-insulating coating . The waterborne epoxy corrosion-resistant heat-insulating coating prepared according to the technical scheme has the characteristics of excellent stability and mechanical properties and has a wideprospect in development of building material technical industry.

Description

technical field [0001] The invention discloses a preparation method of a water-based epoxy anti-corrosion and heat-insulating coating, which belongs to the technical field of building materials. Background technique [0002] Anti-corrosion and heat-insulating coatings are generally divided into conventional anti-corrosion coatings and heavy-duty anti-corrosion coatings, which are an indispensable coating in paint coatings. The purpose of coating the surface with heat-insulating and anti-corrosion coatings is to block, reflect, and radiate solar energy, reduce the temperature of the surface and interior of metal objects, and reduce energy consumption for cooling; the second is to shield water vapor, oxygen, and chloride ions and enhance the coating The anti-rust and anti-corrosion properties of the metal surface can improve its service life. Therefore, the selected pigments and fillers must have the following four characteristics: (1) Low density of pigments and fillers, sma...
