Problems solved by technology

The main disadvantage of this kind of coating is that the elasticity of the coating film is easy to age, the hardness is not good, and it cannot effectively protect the strength of the bottom layer of the wall, resulting in cracking and falling off of the wall surface, which not only affects the appearance of the building, but also cracks on the wall surface, causing the wall surface to crack and fall off. water leakage

Abstract

The invention discloses a matte waterborne coating. The matte waterborne coating contains low polymer polyol, maleic anhydride, methyl methacrylate, hydroxyl ethyl acrylate, hydroxylation fiber resin, polyether sulfone resin, polysorbate, sodium hexametaphosphate, organic silicon emulsion, epoxy silane modified silica sol, cross-linked polyethylene, butyl peroxybenzoate, sodium silicate, melamine polyphosphate, pentaerythritol, aluminum silicate fiber, silica, hydroxyethyl cellulose, an antibacterial preservative, waterborne polyurethane resin, acrylate, polyvinyl alcohol, light calcium carbonate, titanium dioxide, waterborne epoxy modified resin, Ni, Zn, water and other raw materials. Due to the fact that the matte waterborne coating contains Ni, Zn and other components, the matte waterborne coating has high-temperature resistance and corrosion resistance, meets coating requirements in various occasions, does not contain a toxic organic solvent, is pollution-free, and also has the advantages of no cracking of a paint surface, ageing resistance, strong adhesive force and the like.

Description

technical field [0001] The invention relates to a matte water-based coating and a preparation method thereof, belonging to the technical field of coatings. Background technique [0002] In recent years, from the viewpoint of environmental problems, the transition from organic solvent-based paints to water-based paints has been progressing. In addition, coatings are generally required to have excellent coating properties such as water resistance, alkali resistance, abrasion resistance, and weather resistance. [0003] Water-based coatings are coatings that use water as a dispersion medium and thinner. Compared with organic solvent-based coatings, water-based coatings not only reduce the emission of volatile organic solvents, but also save resources and energy (energy consumption is required to produce solvents), and are convenient. Transport and storage. With the enhancement of people's awareness of environmental protection, the relevant environmental protection regulations...
