Problems solved by technology

24 hours after the construction of the existing paint, the solvent is basically evaporated, but there is still a pungent smell from the residual alkyd resin on the furniture
The existing polyurethane clear paint film is easy to scratch and wear after drying, the hardness is not high, and the adhesion of the paint surface is not strong and easy to fall off

Abstract

The invention relates to a polyurethane top-coat paint and a preparation method thereof, and particularly relates to a polyurethane matt wearable top-coat paint for removing an odor and a preparation method thereof. The polyurethane matt wearable top-coat paint can be applied to office suite furniture, and belongs to the field of a household decorative coating. The polyurethane matt wearable top-coat paint for removing the odor is prepared from a primary agent, a curing agent and a diluent according to the ratio of (1-1.4):(0.5-0.7):(0.7-1.2), wherein the primary agent comprises the following components in parts by weight: 68-80 parts of alkyd resin, 5-10 parts of vinyl chloride-acetate copolymer, 0.5-1.8 parts of dispersant, 0.3-1.5 parts of flatting agent, 0.1-0.5 parts of defoamer, 2-6 parts of anti-settling agent, 2-8 parts of glass powder, 0.5-1 part of wax powder, 2-7 parts of matte powder and 3-8 parts of mixed environment-friendly solvent. The prepared polyurethane matt wearable top-coat paint for removing the odor is not only low in odor after construction, but also good in scratch resistance performance of the film, good in abrasive resistance, and good in environmental performance.

Description

technical field [0001] The invention relates to a polyurethane clear topcoat and a preparation method thereof, in particular to a polyurethane odor-clear matt wear-resistant clear finish and a preparation method thereof. The polyurethane odor-free matt wear-resistant clear finish can be applied to office suite furniture , belongs to the field of paint for home decoration. Background technique [0002] With the increasingly higher requirements for paint environmental protection and performance, especially the irritating smell after paint construction has been paid more and more attention by people, it is hoped that the office furniture can be lived in as soon as possible after the construction or decoration of the house. . 24 hours after the construction of the existing paint, the solvent basically evaporates completely, but there is still the pungent smell of the residual alkyd resin on the furniture. The paint film of the existing polyurethane clear finish paint is easy t...
