Abstract

The invention discloses a water-based super weather-resistant modified silicone-acrylic acid metal paint coating. The water-based super weather-resistant modified silicone-acrylic acid metal paint coating mainly comprises, by mass, 75 to 85 parts of water-based organosilicon modified acrylic emulsion, 5 to 8 parts of aluminium paste, 0.01 to 0.03 part of butyl cellosolve), 1 to 5 parts of a levelling agent, 1 to 5 parts of a film forming auxiliary agent and 8 to 15 parts of water. The water-based super weather-resistant modified silicone-acrylic acid metal paint coating can be used for one-step spraying; the surface of obtained paint film is compact, bright and smooth; and the obtained paint film possesses high tenacity, and excellent impact resistance and stain resistance. Coating of the water-based super weather-resistant modified silicone-acrylic acid metal paint coating is capable of obtaining endurance, acid and alkali resistance, effective inhibition on growth of algae and fungus, and environmental protection performance. The properties can be maintained unchanged under long-term complex weather conditions for more than 3000 hours; simulation of decorative effect of aluminium-plastic panel can be realized; dazzling metallic luster can be observed; it is difficult for dust to accumulate on the paint film; and the paint film is clean and beautiful.

Description

technical field

[0001] The invention relates to a composition coated on the surface of objects, in particular to a water-based super-weather-resistant modified silicon-acrylic metal paint, which has the characteristics of imitating aluminum-plastic panels and is especially suitable for building exterior wall decoration. Background technique

[0002] In the exterior wall decoration of buildings, the general exterior wall paint that is usually used lacks the requirements of beauty and individuality. However, thick-layer decorations, such as ceramic tiles or marble, have defects such as waste of resources, failure to meet energy conservation and environmental protection requirements, and danger of falling from high altitudes. Solvent-based coatings have the disadvantages of being toxic, harmful, and not environmentally friendly. In order to solve the technical problems existing in the existing coatings, modified coatings emerged as the times require. They mainly use water-base...
