Abstract

The invention discloses water-based metal paint with super weatherability. The water-based metal paint is prepared from the following ingredients in parts by weight: 30 to 40 parts of acrylic acid modified alkyd resin, 10 to 15 parts of acrylic acid modified emulsion, 2 to 5 parts of acetoacetoxy ethyl methacrylate, 6 to 10 parts of water-based amino resin, 2 to 5 parts of rheological modified resin, 1 to 3 parts of polyester resin, 5 to 10 parts of light diffusion agents, 25 to 30 parts of modified aluminum powder, 0 to 4 parts of cellulose acetate butyrate, 1 to 5 parts of butyl cellosolve, 3 to 5 parts of polyethylene wax, 5 to 8 parts of deionized water, 30 to 40 parts of long afterglow luminous powder, 0.5 to 3 parts of modified bentonite, 1 to 3 parts of water-based organic silicon defoaming agents and 2 to 5 parts of water-based organic silicon flatting agents.

Description

technical field [0001] The invention relates to a coating, in particular to a water-based metal coating with super weather resistance. Background technique [0002] Corrosion of materials is a serious problem worldwide. Corrosion not only consumes precious wealth, but also destroys the normal operation of many activities such as production and life. The annual loss caused by metal corrosion in my country is as high as tens of billions of RMB, accounting for about 4% of the gross national value. With the increase of metal consumption, the loss will continue to increase. Such an astonishing loss stimulates the development of anti-corrosion coatings. At the same time, the coating film is prone to embrittlement, chalking, discoloration, loss of light, peeling and other problems when exposed to outdoor environmental conditions. The coating film needs to have high weather resistance. Therefore, the research and development of weather-resistant water-based coatings is urgent. C...
