Abstract

The invention provides an anticorrosive heat-insulating coating. The anticorrosive heat-insulating coating comprises the following components in parts by weight: 50-60 parts of purified water; 1-2 parts by weight of a coalescing agent; 2-3 parts by weight of a preservative; 5-10 parts by weight of talcum powder; 1-2 parts by weight of a dispersant; 0.1-0.2 part by weight of a defoaming agent; 5-10 parts by weight of porous powder quartz; 5-10 parts by weight of ground calcium carbonate; 30-50 parts by weight of a styrene-acrylic emulsion; 5-10 parts by weight of hollow glass beads; and 0.1-0.2 part by weight of graphene. By adding graphene, the problem of static electricity is solved, and the heat preservation performance and the corrosion resistance of the coating are normally reserved and are not affected. Therefore, the building coating which is good in stability and capable of solving the problem of static electricity is obtained.

Description

technical field [0001] The invention relates to an anti-corrosion and heat-insulating material, in particular to a water-based anti-corrosion and heat-insulating coating capable of preventing static electricity and a preparation method thereof. Background technique [0002] "Heat insulation coating" is a recently developed functional water-based coating that blocks, reflects, and radiates near-infrared heat from sunlight, which can insulate and cool the roof, 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 coating...
