Production method of modified interior and exterior wall coating

Abstract

The invention discloses a production method of a modified interior and exterior wall coating. The modified interior and exterior wall coating comprises, by weight, polyurethane, epoxy resin, acrylic resin emulsion, mixed fiber, rosin, an elastic resin solution, a halogen free fire retardant, an anti-radiation material, a pigment, an anti-foaming agent, a wetting agent, a leveling agent, and water.The mixed fiber is prepared from glass fiber and sisal fiber at a certain ratio. No benzene compound is added; the modified interior and exterior wall coating is nontoxic; pollution is low; the mixedfiber is prepared from glass fiber and sisal fiber, so that combination of the advantages and disadvantages of the two kinds of fiber is realized, and coating wear resistance and toughness are improved; the anti-radiation material is added, so that coating anti-radiation performance is improved; the fire retardant is added, so that coating fire resistance is improved; rosin is added, so that thecoating is provided with delicate fragrance. The production method is simple in operation; the needed raw materials are easily available; the cost is relatively low; and the production method is worthy of popularization.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a production method of modified interior and exterior wall coatings. Background technique [0002] Paint, what we usually call paint is just one of them, which refers to the ability to form a film on the surface of an object under certain conditions for protection, decoration or other special functions (insulation, rust prevention, mildew resistance, heat resistance, etc.) A class of liquid or solid materials. Because most of the early coatings used vegetable oil as the main raw material, they were also called paints. Now synthetic resin has replaced vegetable oil, so it is called paint. Coatings are not liquid, and powder coatings are a large category of coatings. Coatings generally consist of four basic components: film-forming substances (resins, emulsions), pigments (including extender pigments), solvents and additives (auxiliaries). [0003] The coating belongs to the o...

Problems solved by technology

[0004] However, most of the existing interior and exterior wall coatings use glass fibers, but the wear resistance of glass fibers is poor; and the coatings have poor radiation resistance and poor flame retardancy.
