Abstract

The invention provides top-coat paint which comprises an A agent and a B agent, wherein by weight parts, the A agent comprises 60-90 parts of alkyd resin, 0.2-0.5 part of a flatting agent, 0.2-0.5 part of a de-foaming agent, 1-3 parts of 5,5-dimethyl-1-pyrroline-N-oxide and 7-20 parts of a solvent; the B agent is a polyurethane curing agent; the mass ratio of the A agent to the B agent is 1 : (0.5-1.2). The top-coat paint provided by the invention comprises the alkyd resin, the polyurethane curing agent and 5,5-dimethyl-1-pyrroline-N-oxide; the alkyd resin interacts with the polyurethane curing agent to obtain a polymer with high cross-linking rate, so that the top-coat paint is good in high-temperature-resistant performance; in addition, due to the addition of 5,5-dimethyl-1-pyrroline-N-oxide, the high-temperature-resistant performance of the top-coat paint is further improved.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a clear finish paint. Background technique [0002] The clear topcoat is a coating composed of resin as the main film-forming substance plus a solvent. Its main components are resin and solvent or resin, oil and solvent. The clear topcoat is applied on the surface of the object to form a protective, decorative and special coating film, which forms a smooth film after drying, showing the original texture of the object surface. The clear topcoat can be used for coating furniture, floors, doors and windows, and automobiles; it can also be used to add pigments to the clear topcoat to make enamel paint, or to add dyes to the clear topcoat to make colored varnish; it can also be used to fix sketches, For gouache drawings, etc., the clear topcoat can prevent the oxidation of the drawings and prolong the preservation time of the drawings. The clear topcoat has the advantages of good t...
