Problems solved by technology

There are many ways to reduce VOC in the coating industry, but undoubtedly the most important method is to use water-based (WB) coatings. Water-based epoxy coatings are currently widely used on wooden doors due to their good wear resistance and pressure resistance, and are not prone to coating defects. industry, but the water-based epoxy coating has the disadvantage of dispersion stability, and it is prone to delamination after long-term storage, which needs to be solved urgently

Abstract

The invention discloses a high-stability wood door water-based epoxy resin coating which comprises first materials and second materials. The first materials comprise, by weight, 70-110 parts of main materials, 2-8 parts of aluminum nitride, 1-5 parts of melamine resin, 1-4 parts of magnesium hydroxide, 2-6 parts of expanded perlite, 1-4 parts of diatomite, 1-4 parts of mica powder, 0.5-1.2 parts of zinc oxide, 2-6 parts of composite dispersing agents, 3-7 parts of plasticizers, 1-2 parts of defoaming agents, 1-2 parts of wetting agents and 1-2 parts of leveling agents. The second comprise, byweight, 5-9 parts of aminoethyl piperazine, 1-3 parts of propanediol butyl ether, 2-4 parts of 2, 2, 4-trimethyl-1, 3-pentanediol diisobutyl acid ester and 20-40 parts of deionized water. According tothe high-stability wood door water-based epoxy resin coating, adhesive force between the coating and a coating substrate is good, toughness and hardness can be balanced, mechanical properties are excellent, and the dispersion stability of the coating is good when the coating stands for a long time.

Description

technical field [0001] The invention relates to the technical field of water-based paint, in particular to a water-based epoxy resin paint for wooden doors with high stability. Background technique [0002] At present, in the domestic wooden door industry, most of the coatings used on the surface of wooden doors are solvent-based. Due to growing concerns about the adverse effects of organic solvents on the environment and human health, there is a demand to reduce the content of volatile organic compounds (VOC) in products. There are many ways to reduce VOC in the coating industry, but undoubtedly the most important method is to use water-based (WB) coatings. Water-based epoxy coatings are currently widely used on wooden doors due to their good wear resistance and pressure resistance, and are not prone to coating defects. industry, but water-based epoxy coatings have the disadvantages of dispersion stability, and they are prone to delamination after being placed for a long t...
