Problems solved by technology

At present, the waxy feel agents on the market are mainly silicone-based waxy feel agents, which are directly sprayed on the surface of synthetic leather and are very convenient to use; however, these waxy feel agents are oily feel agents and usually contain a certain amount of organic solvents , the organic solvent contained in it will enter the air in a slowly volatilized manner after spraying, affecting air quality

Abstract

The invention discloses waterborne smooth wax handle agent applicable to synthetic leather and relates to the technical field of synthetic leather functional aids. The waterborne smooth wax handle agent is prepared from, by weight, 15-20 parts of soybean protein fiber / poloxamer, 3-5 parts of chitosan / hydroxypropyl methyl cellulose, 3-5 parts of carbomer resin, 2-3 parts of down fiber / polyvinylpyrrolidone, 1-2 parts of polyvinyl-chloride-modified activated white clay, 0.5-1 part of pregelatinized starch, 0.5-1 part of sepiolite powder, 0.5-1 part of tea seed powder, 0.3-0.5 part of carrageen, 0.3-0.5 part of polyaluminum sulfate, 0.05-0.1 part of nano zinc borate, and 100-150 parts of water. The waterborne smooth wax handle agent imparts significantly good slippery wax handle and good scratch resistance to the processed synthetic leather, so that it is ensured that the processed synthetic leather remains excellent in slippery wax handle during long-term usage.

Description

[0001] Technical field: [0002] The invention relates to the technical field of functional additives for synthetic leather, in particular to a water-based wax-sliding feel agent suitable for synthetic leather. [0003] Background technique: [0004] Synthetic leather is made of impregnated non-woven fabric as a mesh layer and a microporous polyurethane layer as a grain layer. Its front and back are very similar to leather, and has a certain degree of air permeability, which is closer to natural leather than ordinary artificial leather. It is widely used in making shoes, boots, bags and ball games. [0005] During the processing of synthetic leather, functional additives need to be added to enhance the feel, appearance quality and use quality of synthetic leather products. Waxy feel agent is a special functional additive for synthetic leather, which is used to give synthetic leather a good waxy feel. At present, the waxy feel agents on the market are mainly silicone-based wax...
