Contamination-resistant and heat insulation aqueous coating and preparation method thereof

Abstract

The invention discloses a contamination-resistant and heat insulation aqueous coating. The contamination-resistant and heat insulation aqueous coating is characterized in that the contamination-resistant and heat insulation aqueous coating is prepared from the following raw materials in parts by weight: 48-53 parts of aqueous polyurethane resin, 20-26 parts of an elastic pure acrylate emulsion, 1-2 parts of polyoxypropylene glycol, 1-2 parts of melamine, 1-2 parts of a fluorescent whitener, 0.8-1.6 parts of triethanolamine, 1-2 parts of diethylenetriamine, 0.5-0.8 part of dimethicone, 1-2 parts of guar gum, 2-3 parts of titanium dioxide, 1-3 parts of silicon oxide, 0.4-0.6 part of polyoxyethylene cetyl ether, 2-3 parts of methyl-ethyl paraben, 1-2 parts of sodium stearate, 1-3 parts of bentonite, 2-3 parts of bamboo powder, 7-9 parts of heat insulation slurry, 0.7-1.4 parts of diacetone acrylamide and 14-20 parts of deionized water. The aqueous coating disclosed by the invention has excellent heat resistance, heat insulation, contamination resistance, corrosion resistance and the like, water is adopted as a dilution solvent, and the aqueous coating is safe, environment-friendly, low in toxicity and low in cost; and furthermore, the aqueous coating is good in film-forming ability after curing, smooth, high in hardness, good in adhesion and less prone to shedding and has a wide range of applications.

Description

technical field [0001] The invention relates to a coating and a preparation method thereof, in particular to a stain-resistant and insulating water-based coating and a preparation method thereof. Background technique [0002] Coating is a material that can be coated on the surface of an object by different construction techniques to form a solid film with strong adhesion, certain strength and continuity. The film formed in this way is commonly called a coating film, also known as a paint film or a coating. With the increasing awareness of environmental protection, countries all over the world have successively formulated the limit standards and regulations for volatile organic compounds (VOC) emissions. Solvent-based coatings are an important source of VOC, which cause great pollution to the environment and great harm to the human body. At the same time, there are safety hazards such as flammability and explosion in construction, storage, and transportation. Water-based pa...
