Abstract

The invention discloses a water-based inorganic three-proofing coating and a preparation method thereof. The water-based inorganic three-proofing coating comprises the following components in parts byweight: 300 to 312 parts of water, 4 to 8 parts of a dispersant, 0.3 to 0.8 part of a neutralizer, 3 to 4 parts of an antifoaming agent, 180 to 200 parts of titanium dioxide, 180 to 200 parts of calcium carbonate, 3 to 5 parts of cellulose, 8 to 12 parts of an anionic organosilicon emulsion, 4 to 6 parts of a stabilizing agent, 210 to 220 parts of potassium silicate and 45 to 55 parts of a pure acrylic emulsion, wherein the anionic organosilicon emulsion comprises the following components: octamethylcyclotetrasiloxane, an emulsifier, deionized water, sodium hydroxide, gamma-glycidoxypropyltrimethoxysilane and a phenolic aldehyde amine curing agent. The water-based inorganic three-proofing coating has the advantages of suitability for low-temperature construction, high drying speed in a low-temperature environment, short curing time, high adhesive force and excellent sound absorption and noise reduction effect.

Description

technical field [0001] The invention relates to the technical field of architectural coatings, in particular to a water-based inorganic three-proof coating and a preparation method thereof. Background technique [0002] Traditional oil-based paints use organic solvents as solvents, which will release volatile organic compounds (VOCs), which can easily pollute the atmosphere and pose a fire hazard during construction. With the improvement of people's living standards, consumers' requirements for quality of life have also been greatly improved, and more and more attention has been paid to the problem of decoration pollution. Not only pay attention to the general performance of the coating, but also pay more attention to the non-toxicity and harmlessness of the coating to the human body and the environment, because a healthy living environment is the basis of a good quality of life. Water-based inorganic coatings, as a kind of eco-friendly coatings, have been concerned by the ...
