Abstract

The invention discloses a high-wear-resistance water-based elastic coating for surface decoration of a plastic material. The high-wear-resistance water-based elastic coating is prepared by mixing an agent A for a resin base material part and an agent B for a curing agent part according to a certain ratio. The agent A is prepared by stirring water-based polycarbonate polyurethane, water-based polyether polyurethane and water-based hydroxy acrylic acid, adding deionized water and a neutralizer, carrying out stirring, adding a water-based dispersing agent, a water-based wetting leveling agent, water-based wax liquor and a water-based thixotropic agent, conducting stirring, adding a water-based defoamer, and conducting stirring; and the agent B is prepared by stirring a curing agent and a diluent. Compared with the prior art, full-water-based dispersion resin is selected as a main connecting material, the problem of VOC emission caused by high-solvent volatilization of an oil-based elasticcoating is avoided; the VOC content of a system of the invention is smaller than 200 g / L, meeting the VOC control requirements of national environmental protection in China; through the collocation design of the water-based resin with different characteristics, the problem that wear resistance and good hand feeling cannot be obtained at the same time is solved, and the balance of the wear resistance and the hand feeling is realized by adding auxiliaries.

Description

technical field [0001] The invention belongs to coating technology, and in particular relates to a highly wear-resistant water-based elastic coating for surface decoration of plastic materials. Background technique [0002] The existing plastic elastic coatings are mainly solvent-based elastic coatings. The resin system contains a large amount of volatile organic solvents, and the diluent is also an organic solvent. The content of xylene, methyl ethyl ketone, and ethyl acetate exceeds 60%, and the VOC is seriously exceeded. Not environmentally friendly; these solvents are flammable and explosive, and there are greater safety risks in production, transportation, storage, and construction. Prior art CN106221339A A wear-resistant water-based elastic paint developed in a wear-resistant and scratch-resistant water-based elastic paint is used in metal materials with excellent wear resistance, but the handle is hard, and the wear resistance and feel cannot be balanced, and the wear...
