Ultraviolet curable water-based antibacterial paint used for wooden products

Abstract

The invention belongs to the field of paint and in particular relates to ultraviolet curable water-based antibacterial paint used for wooden products. The water-based antibacterial 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, 10-15 parts of graphene, 5-10 parts of nano titanium dioxide sol and 2-5 parts of silver ion solution. The water-based antibacterial paint can meet the requirements of high performance and environmental protection, has composite antibacterial ability 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 antibacterial coating for wood products. Background technique [0002] Solvent-based coatings, after long-term development, have high decorative properties, durable protection, and multi-functionality; 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 coa...

Problems solved by technology

However, at present, there are factors such as poor antibacterial effect, short antibacterial timeliness and poor scrub resistance of antibacterial coatings on the surface of wood products, which seriously restrict its application range.
