Abstract

The high-performance aluminium imitating finish paint is compounded with polymer emulsion, stuffing, pigment, assistant and water in certain proportion. It forms tough paint film with high adhesive power, high water and alkali resistance, one-way air permeability and hydrophobicity, certain mildew proof and self-cleaning performance. It is used in decoration of outer wall.

Description

Technical field: [0001] The invention relates to a surface coating for plastering walls, in particular to a silicon-fluorine modified polymer imitation aluminum board surface coating suitable for water-based exterior walls. Background technique: [0002] The materials used in the current aluminum panel curtain wall have high energy consumption (20,000 kilowatts of energy loss per square meter of aluminum panel), large consumption of mineral resources (10 tons of aluminum ore per square meter of aluminum panel), and the production of this material causes a lot of pollution; aluminum panel construction At the same time, the cost of the aluminum plate is high (800-1200 yuan / square meter); the aluminum plate curtain wall is easily corroded by the air, and the color is single. Invention content: [0003] The object of the present invention is to provide a silicon-modified acrylic imitation aluminum board surface coating which is modified by chemical bonding with silicon element...
