Aqueous heat-insulating anticorrosive paint

Abstract

The invention discloses an aqueous heat-insulating anticorrosive paint; the off-white aqueous heat-insulating anticorrosive paint is prepared by utilizing styrene-acrylic emulsion and nano SiO2 slurry as main film forming matters under the coordination of various functional pigments and fillers, various auxiliaries and brownish black slurry through conventional single-component coating preparation technologies. The aqueous heat-insulating anticorrosive paint provided by the invention can block, reflect, irradiate and save solar energy and reduce temperature of solar energy, and also can be featured with rust resistance, rot resistance, green and environmental protection, weather resistance, durability and good decoration property simultaneously. The aqueous heat-insulating anticorrosive paint is widely applied to heat insulation and anticorrosion for metal surfaces of metal structure buildings, chemical storage tank, locomotive carriages, cold water towers and so on.

Description

[0001] Field of invention [0002] The invention relates to the technical field of metal structure building surface coatings, in particular to a water-based heat-insulating and anti-corrosion coating. Background technique [0003] At present, the heat insulation and anticorrosion of the surface of metal structure buildings is mainly based on anticorrosion. Generally, the inner and outer walls of the building are sprayed or brushed with anticorrosive coatings of various properties to form inner and outer anticorrosion layers. In terms of heat insulation, the surface is usually covered with thermal insulation materials to play the role of thermal insulation. Among the commonly used anti-corrosion coatings, polymer epoxy resin anti-corrosion coatings are widely used, also known as ceramic epoxy coatings. Ceramic epoxy coatings are generally mixed with polymer epoxy resin, toughening agent, leveling agent, quartz powder and curing agent in a certain proportion. Although this trad...

Problems solved by technology

Ceramic epoxy coatings are generally mixed with polymer epoxy resin, toughening agent, leveling agent, quartz powder and curing agent in a certain proportion. Although this traditional ceramic epoxy coating is widely used, there are also The following disadvantages: Quartz powder cannot be evenly distributed into the paint coating, which reduces the adhesion of the coating, and the coating is easy to fall off, which affects the anti-corrosion quality of the coating, especially the poor thermal insulation performance

If spraying or brushing anti-corrosion paint on the cladding layer, the construction is complicated and the bonding force between the heat insulation layer and the anti-corrosion layer is lower, and it is easy to fall off, resulting in a reduction in the life of the metal structure building.
