Problems solved by technology

The one-component water-based glass paint prepared by polyurethane water dispersion, water-soluble polyacrylic resin, urethane type and modified acrylic resin has poor adhesion, alcohol resistance, water resistance, abrasion resistance and poor wear resistance on the glass substrate. Low hardness and other disadvantages lead to short service life, while the ratio of water-based acrylic resin to amino curing agent and the amount of coupling agent are the main factors affecting the water resistance, alcohol resistance, abrasion resistance and hardness of the paint film

Embodiment 1

[0017] An environmentally friendly water-based glass baking varnish, the baking varnish is composed of the following components in parts by weight: 90 parts of water, 8.5 parts of amino curing agent, 70 parts of water-based acrylic resin, 0.35 parts of defoaming agent, 0.25 parts of wetting agent, and 0.2 parts of leveling agent 0.9 parts, 0.9 parts of coupling agent, 0.15 parts of anti-scratch agent and 0.5 parts of pH regulator.

[0018] The amino curing agent is an amino resin curing agent, and the amino resin curing agent plays the role of quickly curing the baking varnish.

[0019] The coupling agent is a siloxane coupling agent, and the siloxane coupling agent reacts with the key curing agent to bond or form entanglements, so as to improve adhesion and reduce the penetration of water or alcohol substances into the substrate Function, increasing the water resistance and alcohol resistance of the baking paint.

[0020] The pH regulator is hydrogen chloride solution.

Abstract

The invention relates to environment-friendly water-based glass baking lacquer. The glass baking lacquer is composed of, by weight, 90-120 parts of water, 7-8.5 parts of amidogen curing agents, 70-85 parts of water-based acrylic resin, 0.35-0.8 part of antifoaming agents, 0.25-0.35 part of wetting agents, 0.2-0.3 part of flatting agents, 0.9-1.2 parts of coupling agents, 0.15-0.25 part of anti-scratching agents, and 0.5-0.7 part of PH modifiers, wherein the amidogen curing agents are amino resin curing agents, and the coupling agents are siloxane coupling agents. According to the environment-friendly water-based glass baking lacquer, the performance of the water-based glass baking lacquer is changed by regulating the ratios of the water-based acrylic resin and the amidogen curing agents and the usage of the coupling agents, the prepared environment-friendly water-based glass baking lacquer has a high hardness value, high water resistance, high alcohol resistance, high abrasion resistance and high dry and wet adhesive force, service life is long, and environment friendliness is high.

Description

technical field [0001] The invention relates to a baking varnish, in particular to an environment-friendly water-based glass baking varnish. Background technique [0002] Baking varnish is a new method (process) of spraying paint in furniture manufacturing. The method is: spray several layers of paint on a substrate (usually a high-density board) that has been polished to a certain degree of roughness, and bake it at a high temperature to finalize the shape. . At present, this process has higher requirements on paint and good color rendering. The baking varnish process has been widely used in furniture products such as sliding doors, cabinets and desks, and it has also begun to penetrate into surface processing processes of other materials. Baking varnish is divided into two categories, one is low-temperature baking varnish with a curing temperature of 90°-100°, and the other is called high-temperature baking varnish with a curing temperature of 230°-240°. [0003] At pre...
