A kind of polyurethane wood floor paint with formaldehyde removal function and preparation method thereof

Abstract

The invention relates to a polyurethane wood floor paint with a formaldehyde removal function and a preparation method thereof. The polyurethane wood floor paint with a formaldehyde removal function is formed by mixing a hydroxyl component and an NCO component at a mass ratio of 1:0.8-1.2 , wherein the hydroxyl component and parts by weight ratio are as follows: 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 defoamer, 0.1-0.5 parts of leveling agent, 0.1-0.5 parts of drier; wherein the NCO components and parts by weight are as follows: Xylene 5‑12 parts, n-butyl acetate 18‑24 parts, ethyl acetate 8‑10 parts, TDI‑TMP30‑40 parts HDI trimer 5‑15 parts, moisture curing agent 15‑20 parts, dehydrating agent 0.5 ‑1 serving. The polyurethane wood floor paint prepared by the invention has the function of removing formaldehyde, and the coating is wear-resistant, impact-resistant and has good adhesion.

Description

technical field [0001] The invention relates to a glossy varnish used on wooden floors for home improvement, in particular to a polyurethane wood floor paint with formaldehyde removal function 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 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 ability to remove formaldehyde is a matter of great concern to residents. The release of formaldehyde is not conducive to the health of the home environment. Therefore it is imperative to develop a kind of polyurethane wood floor paint with formaldehyde removal function. Contents of the invention [0003] The purpose of ...
