Abstract

The invention relates to the technical field of polyurethane paints, and especially relates to a novel polyurethane paint. The novel polyurethane paint comprises, by mass, 60-78 parts of alkyd resin, 22-30 parts of petroleum resin, 20-35 parts of an organosilicon emulsion, 5-10 parts of xylene used for modifying polyester, 4-9 parts of acrylic polyol, 5-12 parts of polyurethane, 10-15 parts of an aqueous epoxy resin curing agent, 3-10 parts of hydroxypropyl methyl cellulose ether and 3-8 parts of an antifoaming agent. A paint film formed by the polyurethane paint prepared by adopting the above formula is bright, full and hard, has wear resistance, and has strong oil, acid and alkali resistance; and the paint has the advantages of good construction property and levelability, strong climate adaptability, convenience in use, and convenience in promotion and application.

Description

technical field [0001] The invention relates to the technical field of polyurethane paint, in particular to a novel polyurethane paint. Background technique [0002] Polyurethane paint is polyurethane paint. It has strong paint film, full luster, strong adhesion, water resistance, wear resistance and corrosion resistance. It is widely used in high-grade wooden furniture and can also be used on metal surfaces. Its shortcomings mainly include problems such as foaming when it is wet, and powdering of the paint film. Like polyester paint, it also has the problem of yellowing. The varnish variety of polyurethane paint is called polyurethane varnish. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a novel polyurethane paint. [0004] In order to solve the above-mentioned technical problems, the novel polyurethane paint of the present invention comprises the following components in parts by mass: 60-78 parts of alky...
