Problems solved by technology

In order to meet consumers' needs for product physical therapy and health care, products that can release negative ions are designed, but most of the existing products have low and unsustainable release, and the negative ion powder is not well dispersed in polyurethane and other polymer slurry and is easy to separate from the leather surface. And other issues

Abstract

The invention discloses negative-ion high-release-amount polyurethane synthetic leather and a manufacturing method thereof. The negative-ion high-release-amount polyurethane synthetic leather is formed by adhering a negative-ion-containing fabric base and a polyurethane resin layer, wherein the negative-ion-containing fabric base is formed by dipping a fabric base in negative-ion-containing power polyurethane slurry, the negative-ion-containing power polyurethane slurry is prepared from N,N-dimethylformamide, polyester type polyurethane resin, an accelerant, a colorant and improved negative-ion powder slurry; the polyurethane resin layer is prepared from polyurethane slurry, N,N-dimethylformamide, improved negative-ion powder slurry, an accelerant and a colorant. According to the negative-ion high-release-amount polyurethane synthetic leather and the manufacturing method thereof, the fabric base is dipped to form a synthetic leather half-finished product with the negative ion release performance, the polyurethane slurry is coated by utilizing a dry process release paper transfer method, and the release amount of negative ions of the finished product is up to 2000 per cc and can sustain for more than one year.

Description

Technical field [0001] The invention belongs to the technical field of synthetic leather, and specifically relates to anion high-release polyurethane synthetic leather and a manufacturing method thereof. Background technique [0002] Polyurethane synthetic leather has the appearance of soft luster, natural, soft hand and strong leather feeling, and has excellent mechanical properties such as excellent adhesion to the substrate, abrasion resistance, flexure resistance, and aging resistance. It also has good cold resistance, It is breathable, washable and easy to process, making it an ideal substitute for natural leather. Polyurethane synthetic leather is widely used in the processing and decoration of men's and women's shoes, sports shoes, casual shoes, sofa furniture, massage chairs, leather goods, leather bags, balls and other sporting goods. [0003] At present, the synthetic leather industry is moving towards ecological and functional development to meet the ever-increasing en...
