Treatment method for waste paint of furniture paint spraying

Abstract

The invention discloses a treatment method for waste paint of furniture paint spraying. The main points of the technical scheme of the treatment method for the waste paint of the furniture paint spraying are that the treatment method comprises the following steps: firstly, collecting and dissolving the waste paint; removing suspended matters, then filtering the waste paint to obtain filtrate; adding an antibacterial agent to the filtrate, then placing the filtrate under an ultraviolet lamp to be irradiated; then drying and cooling the filtrate and adding a polyurethane aqueous dispersion and deionized water for carrying out secondary dissolution, adding a wear-resisting agent, a dispersant, a leveling agent, a film forming agent and a thickener, uniformly stirring with a stirrer, then adding an antibacterial agent, a defoamer and a gloss enhancer, finally adding a buffering agent to adjust the pH value so as to obtain recycled paint. The antimicrobial agent is added in paint, and the filtrate is irradiated with the ultraviolet lamp to remove microorganisms, then the paint is dried and cooled, and redissolved, the polyurethane aqueous dispersion and excessive deionized water are added, the paint is completely dissolved, and then various additives are added, so that original characteristics of the paint are restored, and the paint further has a very good antibacterial effect.

Description

Technical field [0001] The invention relates to a paint recovery method, more specifically to a paint processing method for furniture paint spraying. Background technique [0002] Paint, the traditional Chinese name is paint. The so-called paint is coated on the surface of the object to be protected or decorated, and can form a continuous film firmly attached to the object to be coated. It is usually based on resin, oil or emulsion, with or without pigments, fillers, and corresponding additives. Agent, a viscous liquid prepared with organic solvent or water. [0003] Water-based paint is a relatively new type of paint in the paint market. Its characteristics include: First: Water-based paint uses water as a solvent, which saves a lot of resources, eliminates the risk of fire during construction, and reduces air pollution; The paint only uses a small amount of low-toxic alcohol ether organic solvents, which improves the working environment conditions; second: the water-based paint...

AI Technical Summary

Problems solved by technology

[0004] A large number of water-based paints have been sold out and are widely used in furniture, construction and other industries. At the same time, a large amount of waste paint has also appeared in the process of use. However, after the traditional waste paint treatment method, the color of the recycled product cannot be changed. The purity Not high, without the advantages of the original water-based paint, can not be reused for spraying, a large amount of waste paint is shelved and wasted, causing huge economic losses
