Abstract

High-elasticity abrasion-resistant ball leather comprises a leather base layer, a coating agent and a slide stopping and unsmoothness improving film layer, wherein the leather base layer is coated with the coating agent; the leather base layer is non-woven fabric covered with slurry, cotton blending is carried out on polyester fiber and nylon fiber cotton carding, and then the non-woven fabric is prepared through cotton lapping, needling and shaping; the coating agent is prepared from acid grain black, pupa casein, dioctyl isophthalate, ethyl citrate, paraben, borax, ammonia water, water, carbon black, highalcohol benzoate, dimethyl para-amino octyl benzoate, zinc dialkyl dithiophosphate, vinyl trimethoxy silane, polyvinyl alcohol and sodium pyrophosphate; the slide stopping and unsmoothness improving film layer is prepared from waterborne polyurethane resin, dimethylformamide, pigment with the particle size smaller than 10 micrometers, titanium dioxide, polyacrylate, organic silicone elastomer, Al(OH)3, 2-methyl-5-nitroimidazole-1-ethanol, (1-naphthyl)-N-methyl carbamate.

Description

Technical field [0001] The invention belongs to the leather field, and specifically is a highly elastic wear-resistant ball leather. Background technique [0002] In the prior art ball leather, when used outdoors, the surface of the ball leather is corroded by sunlight, rain, etc., and the surface is easily damaged, making the overall quality of the ball supported by the ball leather poor. The lack of wear resistance of ball leather itself will also affect the service life of ball leather. Summary of the invention [0003] The invention provides a highly elastic wear-resistant ball leather to solve the defects in the prior art. [0004] The present invention is realized through the following technical solutions: [0005] A high-elastic wear-resistant ball leather, comprising a leather base layer, a coating agent coated on the leather base layer, and an anti-slip and astringency-increasing film layer, wherein the leather base layer is a non-woven fabric that has undergone pulping tre...
