Transparent odor-removing anti-collapse polyurethane primer paint for furniture and preparation method of transparent odor-removing anti-collapse polyurethane primer paint

Abstract

The invention discloses transparent odor-removing anti-collapse polyurethane primer paint and a preparation method thereof. The transparent odor-removing anti-collapse polyurethane primer paint consists of components A, B and C, wherein the component A is a transparent polyurethane primer paint composition; the component B is a polyurethane curing agent; the component C is a diluent. When the transparent odor-removing anti-collapse polyurethane primer paint is used, the weight ratio of a main agent to the curing agent to the diluent is 1:(0.5-1):(0.5-0.6); the component A, that is, the transparent polyurethane primer paint composition of the transparent odor-removing anti-collapse polyurethane primer paint comprises the following main components: odor-removing short oil alkyd resin ESC3333B, castor oil alkyd resin 1234, stearic acid zinc powder TV-A, 1000-mesh talcum powder, a defoaming agent BYK052, bentonite anti-sinking slurry, n-butyl acetate and the like; the component B, that is, the curing agent comprises the following main components: toluene diisocynate trimer Bayer1351, a toluene diisocynate affixture L75, n-butyl acetate and the like; the component C, that is, the diluent comprises the following main components: n-butyl acetate, dimethylbenzene, cyclohexanone and propylene glycol monomethyl ether acetic ester. On the basis that the property of ordinary transparent polyurethane primer paint is maintained, the problem that a paint film is collapsed is solved, odor can be rapidly removed, and the primer paint is free of paint film collapse and generally free of odor after 24 hours after construction.

Description

technical field [0001] The invention relates to a polyurethane transparent primer for furniture, in particular to an odor-cleaning and anti-collapse polyurethane transparent primer for furniture and a preparation method thereof. Background technique [0002] Polyurethane transparent primer is an important member of furniture coatings because of its good performance. manufacturer. The so-called subsidence refers to spraying 2-3 times of polyurethane transparent primer, and then spraying 1-2 times of polyurethane matte clear topcoat, at least 3-4 days, as long as one month, it can be seen that there is obvious collapse, that is, the sinking of the wood grain , showing a strip of grooves, which affects the appearance of the furniture. In addition, the smell of furniture after construction is difficult to eliminate for a long time, which has always troubled coating engineers, coating construction personnel, furniture manufacturers and users. Contents of the invention [0003...
