Problems solved by technology

[0006] However, during the use of water-based wood lacquers, it was found that water-based wood lacquers were poor in establishing early hardness and scratch resistance, and the hardness of the paint film only reached 2B after one week; because there was no filling of SiO 2 Matting agent, the paint film has poor scratch resistance and dry heat resistance; in areas with large temperature differences, fine cracks are found in the paint film when the room temperature is 15°C

Embodiment Construction

[0014] Add 20% of the paint weight of quartz powder to the water-based wood paint to be painted. The specification of the quartz powder added to the primer is 4000 mesh, and the specification of the quartz powder in the topcoat is 6000 mesh. 20 minutes, filter and set aside.

[0015] The specific operation process of applying water-based wood paint to wood is as follows:

[0016] Clean up the surface of the wood → polishing with sandpaper → apply embellishing powder → sandpaper → scrape the putty for the first time and polish it with sandpaper → scrape the putty for the second time and polish it with fine sandpaper → apply oil color (add quartz powder) → Apply the first varnish (add quartz powder) → find the color, repair the putty, and polish with fine sandpaper → apply the second varnish (add quartz powder), polish with fine sandpaper → apply the third varnish (add quartz powder) , Polishing→Water sandpaper polishing backlight, waxing, polishing.

Abstract

The invention relates to a method of painting waterborne paint on a wooden product, comprising the following steps: adding quartz powder which account for 15-30 percent of the weight of the waterborne paint to the waterborne paint, stirring evenly the quartz powder to the waterborne paint, standing the mixture for 10-20 min and painting the wooden product. The quartz powder added to the waterborne paint which is used as the priming paint is 4000 mesh, and the quartz powder added to the waterborne paint which is used as the finish paint is 6000 mesh. The waterborne paint to which the quartz powder is added to paint the wooden produce has improved leveling performance, good surface smoothness and hard film, can resist water, rust, corrosion, flow column, ultraviolet radiation, high temperature, and electric arc, is insulating and can be protected against clotting, scribing and scrubbing.

Description

technical field [0001] The invention belongs to the technical field of paint painting, and relates to a method for painting wood products, in particular to a method for painting water-based paint on wood products. Background technique [0002] At present, the wood paints on the market mainly include polyurethane paint, nitro paint and water-based wood paint. Among them, polyurethane paint and nitro paint are traditional solvent-based products. Because of their cheap price and convenient construction, they are the mainstream products in wood paint. [0003] Thinners of solvent-based paints such as polyurethane paint and nitro paint contain harmful solvents such as benzene, toluene, xylene and their derivatives, which can accumulate in the human body, causing respiratory system, liver disease, and leukemia; Free TDI (toluene diisocyanate) in alcohol can cause lesions in the respiratory system and reproductive system. Even long-term low-dose exposure to these harmful substance...
