PU transparent wood combination paint and its coating process

Abstract

The invention relates to woodware combined paint and a coating process of the combined paint, in particular to PU transparent woodware combined paint and a coating process of the combined paint, and belongs to the field of paint for furniture decoration. The PU transparent woodware combined paint comprises a PU seal primer, a PU transparent primer, a colorant and a PU transparent finishing coat, wherein the PU seal primer is prepared from a PU seal primer main agent, a curing agent I and a diluent according to the weight ratio of 1:(0.4-0.6):(0.5-0.8). The PU transparent woodware combined paint disclosed by the invention is not only excellent in color sealing, high in drying speed, fine in grain size and capable of preventing a base material from rib expanding and deforming, but also good in sanding property, and capable of protecting the base material from damage; in addition, the coating process of the PU transparent woodware combined paint disclosed by the invention not only is less in technical procedures, simple in operation, capable of reducing a lot of manpower and material resources to reduce the coating cost, but also can be used to coat the product to enable the finished product to be with clear wood grain, strong stereoscopic impression, and natural and fresh feeling.

Description

technical field [0001] The invention relates to a combination paint for woodware and its coating process, in particular to a PU transparent wood combination paint and its coating process, belonging to the field of furniture decoration paints. Background technique [0002] Water is the number one enemy of the base material. During long-term use, the moisture content of the base material will inevitably change, resulting in intermittent changes in the base material and deformation of the ribs. Therefore, the wood primer needs to be able to penetrate into the internal structure of the base material and block it. The capillary pores in the substrate can reduce the number of open pores in the substrate, increase the number of closed pores, inhibit the penetration of paint moisture, and make the penetration uniform, so that the substrate can absorb the paint evenly. [0003] Because there are various substrates, some have been oxidized and bleached, some have been artificially dye...

AI Technical Summary

Problems solved by technology

Although tannic acid is an inherent component in high-quality substrates, if wood paint is applied directly to the surface of this wood, the discoloration caused by the action of tannic acid and pigments will often cause discoloration on the surface of the paint film or cause the paint film to fall off, etc. series of questions

[0004] The color sealing performance of the wood combination paint in the prior art is relatively poor. In addition, the paint film surface of the coated base material dries slowly, is not wear-resistant, and also emits a strong pungent smell.

[0005] The painting process of furniture and home improvement in the prior art: material processing→material color repair→gas spraying→polishing→grass rubbing→primer spraying→polishing→surface repairing→finish paint, etc., the existing painting process Not only are there many processes, complicated operations, and high painting costs, but also the finished wood grain after painting is unclear and has no three-dimensional effect
