A kind of water-based uv woodware high-gloss clear topcoat and its preparation method and implementation process

Abstract

The invention discloses a water-based UV high-gloss clear finish paint for woodware, a preparation method and an implementation process. The water-based UV wood varnish is formulated in parts by weight, and its formula includes the following raw material components: 85-90 parts of UV polyurethane dispersion; 1.0-2.0 parts of functional monomer; 0.1-0.5 parts of wetting agent; 2.0-4.0 parts of agent; 0.5-1.0 parts of thickening rheology agent; 3.5-4.5 parts of initiator; the balance of water. Since the water-based UV wood high-gloss clear topcoat of the present invention has the advantages of high gloss, good fullness, high hardness, good chemical resistance, fast curing speed, anti-adhesion, anti-scratch, no prickly heat and dark bubble defects, etc., compared with the existing The one-component / two-component water-based high-gloss wood paints on the market have more excellent coating effects.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a water-based UV high-gloss clear topcoat for woodware, a preparation method and an implementation process. Background technique [0002] With the increasing awareness of environmental protection, the use of solvent-based coatings is gradually limited, while water-based wood coatings have the advantages of no pollution to the environment, low VOC emissions, low toxicity, non-flammable, non-explosive, and fire hazards, and are more and more popular among people. Attention and attention. [0003] In recent years, with the rapid development of the national economy and the improvement of the water quality of people's lives, low-pollution, environmentally friendly coatings have become the focus of attention. With the gradual progress of synthesis technology, water-based wood paint has replaced solvent-based wood paint as a protective coating for wood furniture in children's furnitur...

AI Technical Summary

Problems solved by technology

However, due to the poor wear resistance, low hardness, poor adhesion resistance and scratch resistance of one-component water-based high-gloss wood coatings, especially the low gloss fullness (the gloss value of ordinary water-based coatings is generally 91-92, it is difficult to break through) 95) and two-component water-based high-gloss wood coatings have limited pot life, long packaging time, and high-gloss is prone to prickly heat and dark bubbles, etc., restricting the application and development of water-based wood coatings in the furniture industry, especially in the rapid packaging of industrial assembly line production Applications in offices, cabinets, wooden doors and showcase furniture that have high requirements in terms of wear resistance, hardness, scratch resistance, and gloss fullness

[0004] Therefore, it is necessary to solve the problems of traditional single / two-component water-based high-gloss wood paints such as low gloss, poor fullness, low hardness, and easy to cause prickly heat and dark bubbles.
