AI Technical Summary

Problems solved by technology

The high solid content of PU silicate used for film-forming in coatings will affect the transparency of the film; too high or too low viscosity will affect the coating process; wide molecular weight distribution will not reduce the gloss, etc.
Too much matting powder particles in the paint will weaken the scattering of light; too much matting powder will cause the paint to crack after coating and drying; too little matting powder will have no obvious matting effect

Abstract

The invention relates to a furniture product surface leather matting agent. The furniture product surface leather matting agent is composed of silicate ester, sodium silicate, sodium acetate, ethyl acetate, methylbenzene, acetone 5-15 and a cross-linking agent. The furniture product surface leather matting agent overcomes the defect of the prior art that matting of a leather surface can not be achieved and has the obvious advantages that the adopted silicate ester and solvent both have weak solvent property and do little harm to leather, formula is simpler, and operation is more convenient. After black leather is matted by means of matting paint prepared from the furniture product surface leather matting agent, black leather feels fine and smooth, foggy sense is obvious, matte property is high, no bright spot or bright speck appears under light, and no bright spot or bright speck appears after leather is propped up from the back side with a sharp instrument. By using the furniture product surface leather matting agent to prepare paint, damage to leather is small, and flaws on leather can be repaired. Matting can be achieved conveniently when the surface of leather is cleaned.

Description

technical field [0001] The invention belongs to the technical field of matting agents for leather goods, and more specifically relates to a matting treatment agent for leather on the surface of furniture products. Background technique [0002] At present, under the guidance of advocating nature and returning to the social value concept of nature, the pursuit of genuine leather feeling has become the mainstream of the development of the leather field. Leather with no brightness or weak brightness has become one of the main goals of the current leather preparation industry development. In industrial production preparation, the main process of leather preparation with no brightness or weak brightness is surface matting. The existing matting methods are divided into two methods: physical matting and chemical matting. Nowadays, physical matting has become the mainstream method of leather matting. Physical extinction is to add a matting agent to make the surface of the coating u...
