Abstract

The invention relates to a method for producing highly cold-resistant automobile gear sleeve leather. The method comprises the following steps of: coating a polyurethane coating on basic cloth to obtain a wet process semi-finished product; selecting release paper, uniformly coating highly cold-resistant and highly wear-resistant mixed slurry on the front side of the release paper, and drying the release paper to obtain surface layer film release paper; uniformly coating two-liquid mixed slurry having high crosslinking degree on a surface layer film of the surface layer film release paper, drying the surface layer film release paper to obtain the release paper having a transfer film; and jointing the transfer film of the release paper and the wet process semi-finished product, drying the jointed product, and stripping leather from the release paper to obtain the highly cold-resistant automobile gear sleeve leather. A product produced by the method can meet the requirements of highly cold areas on the property of the automobile gear sleeve leather.

Description

technical field [0001] The invention relates to a production method of polyurethane synthetic leather, more specifically a production method of high cold-resistant automobile gear cover leather. Background technique [0002] Polyurethane synthetic leather, referred to as PU synthetic leather, is a kind of imitation leather synthetic leather with various patterns, patterns, functions and handles, which uses various base fabrics as base materials and coats polyurethane resin on the base materials to form them. The traditional PU synthetic leather has poor resilience and poor wear resistance, and cannot meet the characteristic requirements of high cold-resistant automobile gear cover leather. Contents of the invention [0003] The purpose of the present invention is to provide a production method of high cold-resistant automobile gear cover leather, which can meet the characteristics requirements such as high cold resistance in high cold regions. [0004] The present inventi...
