Surface anti-graffiti coating structure of leather and artificial material

Abstract

The invention relates to the technical field of leather, and discloses a surface anti-graffiti coating structure of leather and artificial material. The surface anti-graffiti coating structure comprises a leather body, wherein through holes are formed in the front surface of the leather body; the front surface of the leather body is provided with a tearing groove. The surface anti-graffiti coatingstructure of the leather and artificial material has the advantages that the adhesion forces of ink, dye, colorful dirt and the like can be reduced, and the good anti-graffiti function is realized; after the graffiti condition occurs, the graffiti can be easily erased; a flame-retardant layer and a heat-resistant layer are made of ceramic fibers, and the ceramic fiber is a kind of good fire-resistant material and has the advantages of light weight, high temperature-resistant property, small heat capacity, good heat insulation and isolation property, good high-temperature heat isolation property, no toxicity and the like, so that the high temperature-resistant and flame-retardant abilities of the leather and artificial material are enhanced, and the service life of the leather is prolonged; the heat expansion and cold shrinkage tension at the surfaces of the leather and artificial material is relieved; by arranging the tearing groove, the leather and artificial material can be tailored.

Description

technical field [0001] The invention relates to the technical field of leather, in particular to an anti-graffiti coating structure on the surface of leather and artificial materials. Background technique [0002] Leather is denatured and non-perishable animal skin obtained through physical and chemical processing such as depilation and tanning. Leather is composed of natural protein fibers tightly woven in three-dimensional space. Its surface has a special grain layer with natural texture. Grain and gloss, comfortable to the touch. In the process of human evolution, people found that some plant juices or mineral oils have certain tanning properties for leather. Raw leather is more breathable and antiseptic after being soaked in juice. [0003] During the long-term use of leather and man-made materials, graffiti may be artificially painted on the surface, which seriously affects the aesthetics of leather and man-made materials. Traditional leather and man-made materials have...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide a kind of anti-graffiti coating structure on the surface of leather and artificial materials, to solve the traditional leather and artificial materials proposed in the above-mentioned background technology to graffiti countermeasures less, when the surface of leather and artificial materials is graffiti with dye It is not easy to erase, and it is easy to make the graffiti dye soak into the interior of leather and artificial materials, which will affect its performance.
