Embodiment Construction

[0038] Below in conjunction with example further illustrate the present invention.

[0039] The process steps of the embodiment of the present invention are as follows:

[0040] (1), pre-soaking water: raw hide is weighed as the basal number of step (1) material consumption and bath liquid liquid ratio, apply 0.10% bactericide (Badericides 72, Bright Eagle Xingye Leather Co., Ltd.), 0.15% soaking aid (Humectan RDL (Huiying Xingye Leather Co., Ltd.), 0.4% soda ash, the bath liquid ratio is controlled at 400%, the bath liquid temperature is 20-22°C, the bath liquid pH is 8.8-9.2, the Baume degree is 8, every 60min turns 5min , running for a total of 18 hours, and the next day, the fleshing, trimming, and weighing were carried out sequentially as the material consumption and bath liquid ratio base number from step (2) to step (4).

[0041] The measured water filling data: the loose part of the hide is filled with water by 55%, and the tight part is filled with water by 25% to 30...

Abstract

The invention relates to an antifouling, ultra-low total carbon emission, and wear-resistant cowhide automobile seat leather manufacturing process. The primer coating includes water-based pigment paste, light-resistant coating, light-resistant acrylic resin coating, light-resistant water-based polyurethane, flame-retardant Coatings and cationic oils; intermediate coatings include matting polyurethane, bright polyurethane, crosslinking agents, materials, wear-resistant polyurethanes, carbodiimides, PTFE emulsions, and smog-suppressing materials; top coatings include hand feel agents and cationic oils. The prepared cowhide car seat leather has improved anti-fouling, ultra-low total carbon emission and wear resistance of the car leather on the basis of maintaining flame retardancy, light resistance and low fogging.

Description

technical field [0001] The invention relates to a manufacturing process of automobile seat cushion leather, in particular to a manufacturing process of antifouling, ultra-low total carbon emission and wear-resistant cowhide automobile seat cushion leather. Background technique [0002] China is currently the world's largest car consumer market, with more than 29 million cars produced in 2017, 20% of which are equipped with leather seats. With the prosperity of the automobile market, more and more leather enterprises are paying attention to the business opportunities of automobile tanning. The statistics at the end of 2017 show that in the environment of the general decline in the profits of all products in the national leather industry, only the profits of automobile leather have maintained growth. [0003] Chinese invention patent 201510694401.6 discloses a "flame-retardant, yellowing-resistant, low-atomization cowhide automobile seat leather manufacturing process", which ...
