Abstract

The invention belongs to the field of paint and in particular relates to ultraviolet curable water-based paint used for wooden products. The water-based paint comprises the following raw materials in parts by weight: 40-65 parts of water-based polyurethane acrylate, 10-15 parts of rosin-based hyperbranched polyester acrylic resin, 5-10 parts of 1,6-hexanediol diacrylate, 5-10 parts of acrylic resin, 5-10 parts of nano aluminium oxide dispersion, 2-4 parts of photoinitiators, 0.2-0.5 part of levelling agent, 10-20 parts of water-based organic assistants, 0.2-0.5 part of anti-settling agent, 0.5-1 part of defoaming agent and 10-15 parts of graphene. The water-based paint can meet the requirements of high performance and environmental protection, has high gloss and longer valid time, and has good compatibility with ultraviolet curable resin.

Description

technical field [0001] The invention belongs to the field of coatings, in particular to an ultraviolet-cured water-based coating for wood products. Background technique [0002] Solvent-based coatings, after long-term development, have high decorative properties, durable protection, and multi-functional innovations; but organic solvents volatilize, causing environmental pollution, and most of them are toxic to humans, animals, organisms, and even plants. With the enhancement of people's awareness of environmental protection, water-based coatings are developing rapidly in our country. However, compared with solvent-based coatings, the existing water-based coatings still have problems such as low hardness, poor fullness, high-temperature stickiness, etc., and the construction and drying time is long, which is not suitable for the large-scale production needs of large furniture enterprises. [0003] With the increasing awareness of global environmental protection, the coatings...
