Problems solved by technology

Polishing treatment agent is a finishing agent for garment leather, shoe leather and bag leather. Traditional synthetic leather polishing products basically use nitrocellulose as a carrier and epoxy soybean oil as a throwing aid system. Therefore, it is easy to slick oil, and the hand feeling and light feeling are difficult to be compatible.

Abstract

The invention provides a soundless wax-penetrating polishing agent for synthetic leather and a preparation method thereof. The soundless wax-penetrating polishing agent comprises the following components by weight percent: 10%-15% of organic silicon modified polyurethane resin containing 30% of solids, 5%-10% of cellulose nitrocellulose wetted with 30% ethyl alcohol, 10%-15% of cyclohexanone, 5%-12% of ethylene glycol butyl ether, 40%-45% of n-butyl acetate, 5%-6% of nanometer gaseous silica, 0.2%-0.5% of an extinction powder dispersing agent, 2%-4% of acetyl tributyl citrate and 2%-3% of polyether modified simethicone. After the synthetic leather treated with the treating agent provided by the invention is polished by a polishing wheel, the synthetic leather has high surface luster, feels smooth, is soundless in the process of rubbing the leather surface and has strong fur-stimulated feel.

Description

technical field [0001] The invention belongs to the field of leather treatment, in particular to a silent wax polishing treatment agent for synthetic leather and a preparation method thereof. Background technique [0002] Synthetic leather is a plastic product that simulates the composition and structure of natural leather and can be used as its substitute material. Usually, the impregnated non-woven fabric is used as the mesh layer, and the microporous polyurethane layer is used as the 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. Widely used in making shoes, boots, bags and ball games. Polishing treatment agent is a finishing agent for garment leather, shoe leather and bag leather. Traditional synthetic leather polishing products basically use nitrocellulose as a carrier and epoxy soybean oil as a throwing aid system. Therefore, it is easy to...
