Abstract

The invention discloses environment-friendly porcelain film coating used for an outer wall. The environment-friendly porcelain film coating is prepared from the following ingredients by weight percentage: 40-50% of silica sol dispersion, 1-4% of filters, 30-40% of a silane coupling agent, 5-15% of pigment, 0.1-1% of a leveling agent, 1-3% of a weather proofing agent, 1-3% of an antibacterial agent, 0.5-1.5% of an ultraviolet light absorber, 1-3% of poly-dimethyl hydroxyl silicone oil and 0.5-2% of an organic acid catalyst. A preparation method of the coating comprises the following steps: weighing raw materials for standby use; adding the fillers and the pigment into the silica sol dispersion and dispersing the fillers and the pigment; adding the weather proofing agent, the antibacterial agent, the ultraviolet light absorber and the organic acid catalyst and dispersing the weather proofing agent, the antibacterial agent, the ultraviolet light absorber and the organic acid catalyst; adding the silane coupling agent, the leveling agent and the poly-dimethyl hydroxyl silicone oil and uniformly dispersing the silane coupling agent, the leveling agent and the poly-dimethyl hydroxyl silicone oil, so as to obtain a product. The environment-friendly porcelain film coating product used for the outer wall, which is prepared from the matched materials has the advantages of being excellentin water resistance, weather resistance, soiling resistance, antibacterial property and better in effect; in addition, the preparation process is simpler in and is lower in cost.

Description

technical field [0001] The invention relates to the technical field of porcelain film coatings, in particular to an environment-friendly porcelain film coating for exterior walls.
