AI Technical Summary

Problems solved by technology

However, when the water-based treatment agent is coated on the surface of the artificial leather product, the protective film formed by the water-based treatment agent is easily worn due to the wear or use of the user, and the protective effect on the artificial leather is lost, causing the surface of the artificial leather product to be worn, and the appearance of the artificial leather product is damaged. Inferior texture affects the use of artificial leather products

Abstract

The invention relates to the field of leather surface treatment agents, and particularly discloses a wear-resistant treatment agent for the surface of artificial leather, which is prepared from the following raw materials in parts by weight: toluene diisocynate, polyester polyol, dimethylolpropionic acid, diethylene glycol, diethylene glycol, organic silicon, modified polycarbonate, acetone, triethylamine and water. The preparation method of the modified polycarbonate comprises the following steps: weighing polycarbonate and a modifier, and stirring at 80-90 DEG C to obtain modified polycarbonate, wherein the modifier comprises acetone, pine oil, cobalt trichloride and nano hafnium disilicide powder. According to the surface treating agent, polycarbonate is modified, so that the treating agent has relatively good wear resistance, and 2-(2-mercaptobenzothiazole) succinate chitosan graft is added, so that the interior of the treating agent is networked, and the wear resistance of the treating agent is remarkably improved. The surface treating agent takes water as a solvent, reduces environmental pollution and is green and environment-friendly.

Description

technical field [0001] The application relates to the field of leather surface treatment agents, more specifically, it relates to a wear-resistant treatment agent for artificial leather surfaces and a preparation process thereof. Background technique [0002] Artificial leather includes polyvinyl chloride foamed artificial leather, polyurethane artificial leather produced by transfer coating method, and polyurethane wet-process synthetic leather, which are mainly used in shoemaking, bags, clothing, furniture, trains, civil aviation, automobiles, military fields, building materials and home textiles industry. Surface finishing is an essential process in leather processing. It not only endows the leather with a beautiful appearance, but more importantly improves the physical properties of artificial leather. [0003] Surface treatment agents are divided into water-based and solvent-based. Solvent-based coatings often contain organic solvents, which float in the air after vola...
