Problems solved by technology

[0002] Polyurethane coating is a kind of coating with excellent comprehensive performance, which is widely used in wood decoration and wooden floor. Since wooden furniture or wooden floor will use adhesives containing formaldehyde in the process of manufacture and use, it will slow down during use. It is released slowly. At present, there is no good way to remove formaldehyde in home decoration. Therefore, the removal of formaldehyde is a matter of great concern to residents. The release of formaldehyde is not conducive to the health of the home environment.

Abstract

The invention relates to polyurethane wood floor paint with a formaldehyde removing function and a preparation method thereof. The polyurethane wood floor paint is prepared by mixing hydroxyl components with NCO components according to a mass ratio of 1:(0.8-1.2), wherein the hydroxyl components comprise the following components in parts by weight: 50-60 parts of formaldehyde removing alkyd resin, 10-20 parts of castor oil alkyd resin, 4-5 parts of cyclohexanone, 5-18 parts of n-butyl acetate, 2-5 parts of ethyl acetate, 6-12 parts of xylene, 0.1-0.5 parts of a defoamer, 0.1-0.5 parts of a leveler and 0.1-0.5 parts of a dryer; the NCO components comprise the following components in parts by weight: 5-12 parts of xylene, 18-24 parts of n-butyl acetate, 8-10 parts of ethyl acetate, 30-40 parts of TDI-TMP (toluene diisocynate-trimethylolpropane), 5-15 parts of an HDI (hexamethylene diisocyanate) trimer, 15-20 parts of a moisture curing agent and 0.5-1 part of a dehydrating agent. The polyurethane wood floor paint prepared by the method has the formaldehyde removing function, and a coating is wear-resistant, impact-resistant and good in adhesive force.

Description

Technical field [0001] The invention relates to a bright varnish for home furnishing wood floors, in particular to a polyurethane wood floor paint with the function of removing formaldehyde and a preparation method thereof. Background technique [0002] Polyurethane coating is a kind of coating with excellent comprehensive performance, which is widely used in wood decoration and wood floor. Because wood furniture or wood floor will use formaldehyde-containing adhesives during the manufacturing and use process, it will be slow in use. It is slowly released. At present, there is no good way to remove formaldehyde in home decoration. Therefore, the ability to remove formaldehyde is a problem that residents are very concerned about. The release of formaldehyde is not conducive to the health of the home environment. Therefore, it is imperative to develop a polyurethane wood floor paint with the function of removing formaldehyde. Summary of the invention [0003] The purpose of the pre...
