Abstract

An envirnomental protection type nano-paint with high resistance to ultraviolet ray, bacteria, mildew, brush, acid, and alkali, photocatalyzing function and amphophobic performance is prepared from filming material, nano material chosen from TiO2, SiO2 and zinc oxide, additive and water.

Description

technical field [0001] The invention relates to a coating and its application method, in particular to an environment-friendly nano coating. Background technique [0002] Coating refers to a general term for a class of materials that are applied to the surface of an object and can form a tough protective film. Most of these coatings are viscous liquids or powdery substances that contain or do not contain pigments (fillers). The range of coatings is very wide, including traditional paints, solvent-based coatings produced using various synthetic resins as main raw materials, and modern coatings based on water-based coatings. The film-forming coating of oil-based paint has the advantages of chemical resistance, water resistance, tough coating film, wear resistance, good color retention and strong adhesion, but the biggest disadvantage is that the solvent or some raw materials contained in the oil-based paint are toxic. It can release toxic and harmful gases such as formaldehyd...
