Abstract

The invention provides an elastic coating for leather and a preparation method of the elastic coating. The coating comprises the following components in parts by mass: 40-60 parts of aqueous polyurethane dispersion, 10-30 parts of zinc oxide whisker, 10-20 parts of coloring pigment, 0.03-0.08 part of dibutyltin dilaurate, 0.5-2.5 parts of a silane coupling agent, 1-3 parts of polyethylene wax, 0-20 parts of acetone, 1-4 parts of triethylamine, 2-4 parts of an ultraviolet absorber and 30-50 parts of water. The coating provided by the invention has good antistatic property, high heat resistance, cold resistance and abrasion resistance, anti-bacterial property and anti-algae property; after the coating is applied to the surface of leather, no static electricity is easily produced and leather is protected from dust.

Description

technical field [0001] The invention relates to the field of coatings, in particular to an elastic coating for leather and a preparation method thereof. Background technique [0002] Leather is denatured and non-perishable animal skin obtained through physical and chemical processing such as depilation and tanning. Leather has a wide range of uses and can be used to make leather clothing, leather shoes, sofas, leather bags, etc. We generally use the method of coating to improve the beauty and practical value of leather. Existing coatings for leather on the market have poor antistatic properties, are easily contaminated with dust, and have low heat resistance, cold resistance, and wear resistance, and do not have antibacterial effects. Contents of the invention [0003] Technical problem to be solved: Aiming at the shortcomings of existing leather coatings with low antistatic, heat-resistant, cold-resistant, and wear-resistant properties, the invention provides an elasti...
