Abstract

The invention relates to the industrial field of wood product coating treatment, discloses a modified polyacrylate coating for wooden products, which uses polymerization reaction of 1,3-cyclobutanediol,2,2,4,4-tetramethyl and bisphenol-A dimethylcyclohexane to acrylic ester for control and modification. The modified polyacrylate coating prepared by graft polymerization has excellent comprehensivecharacteristics, including significantly-improved abrasion performance, good solvent resistance, improved light and weather resistance, strong adhesive, good film-forming property, no need of adding film coalescing agents, film-forming temperature up to -5 DEG C, and widely applicable to processing of various wooden products. The invention provides an effective way to improve the abrasion performance, the solvent resistance and other performance of polyacrylate coating for wooden products, which has the advantages of simple process operation, high efficiency, easy operation, safety and reliability, long service life, and is a technical scheme worthy of popularization.

Description

technical field [0001] The invention belongs to the technical field of wood product coating treatment industry, and in particular relates to a modified polyacrylate coating for wood products. Background technique [0002] Wood is the lignified tissue of plants capable of secondary growth, such as trees and shrubs. After the primary growth of these plants ends, the vascular cambium in the rhizome becomes active, developing bast outward and wood inward. Wood is the general term for plant tissues that develop inwardly from the vascular cambium, including xylem and parenchyma rays. Wood plays a great supporting role in human life. According to the different properties and characteristics of wood, people use them in different ways. [0003] Using various woods as raw materials to process wood products with different shapes and functions has broad market prospects. [0004] The scale of development and utilization of wood product coatings is also increasing day by day. Water-...
