Problems solved by technology

[0002] The current basketball materials are usually made of leather, which generally have defects such as poor toughness, weather resistance, thermal stability and corrosion resistance, and poor hydrophobicity. During the process, due to the high difficulty of ball control, once it hits the body, it will easily cause damage to the body, and at the same time, it will easily cause deformation and rupture of the basketball, and the use safety is poor

Abstract

The invention discloses basketball leather. The basketball leather is prepared from the following raw materials, in parts by weight: 65-70 parts of natural latex, 5-7 parts of polyamide wax micro powder, 1-2 parts of calcium palmitate, 0.6-1 part of isothiazolinone, 30-40 parts of fluorinated polymer, 3-4 parts of stearic acid, 0.01-0.02 part of p-toluene sulfonate and 10-12 parts of glass fiber.The basketball leather takes dimethylformamide of polyamide micro powder as a solvent to promote reaction between trimethylolpropane and stearic acid under catalysis of p-toluene sulfonate, the glassfiber is granted with surface plasticity, the dispersion compatibility of the glass fiber in a latex substrate is enhanced, and accordingly the toughness and the anti-tear performance of the finishedproduct leather are improved.

Description

technical field [0001] The invention belongs to the field of leather, in particular to a basketball leather and a preparation method thereof. Background technique [0002] The current basketball materials are usually made of leather, which generally have defects such as toughness, weather resistance, thermal stability, corrosion resistance, and poor hydrophobicity. During the process, due to the high difficulty of ball control, once it hits the body, it is easy to cause damage to the body, and at the same time, it is easy to cause deformation and rupture of the basketball, and the use safety is poor. Contents of the invention [0003] The object of the present invention is to provide a kind of basketball leather and its preparation method aiming at the defects and deficiencies of the prior art. [0004] To achieve the above object, the present invention adopts the following technical solutions: [0005] A kind of basketball leather, it is made up of the raw material of f...
