Problems solved by technology

After long-term updating, the existing water-based paints have been improved to a certain extent in terms of water resistance, solvent resistance, wear resistance, gloss retention, flow and other properties, but the comprehensive performance still needs to be continuously improved. Therefore, an improved paint has been developed. It is very necessary to improve the comprehensive performance of water-based wood paint

Abstract

The invention provides a modified acrylate polyurethane water-based paint for woodware and a preparation method thereof. The water-based paint comprises the following components in parts by weight: 40-60 parts of an acrylate emulsion, 40-55 parts of a polyurethane emulsion, 2-6 parts of polyethyleneimine, 1-3 parts of polyvinyl butyral, 4-7 parts of a coupling reagent, 0.5-3 parts of brucite fiber, 5-8 parts of additives and 10-20 parts of deionized water. The ageing resistance, pollution tolerance, solvent resistance, ultraviolet resistance, abrasive resistance, and the like of the water-based paint film prepared on the basis of the reasonable formula composition and technology modification according to the invention are obviously improved, the overall compatibility is high, the interlayer adhesive force is high, and the water-based paint is transparent, uniform and fadeless and has high economic benefit.

Description

technical field [0001] The invention relates to the technical field of water-based paint and its preparation, in particular to a modified acrylic polyurethane water-based paint for woodware and a preparation method thereof. Background technique [0002] Environmental protection and energy are two major challenges we face in the 21st century. In order to meet this challenge, the wood coating industry is gradually changing from traditional solvent-based coatings with high energy consumption and high pollution to environmentally friendly and resource-saving water-based coatings. In home decoration, the most common ones are water-based paint and oil-based paint. As a substitute for paint, water-based paint has the following advantages: 1. Using water as a solvent saves a lot of resources; eliminates the risk of fire during construction; reduces Air pollution; only a small amount of low-toxic alcohol ether organic solvents are used, which improves the working environment. The or...
