Embodiment 1

[0021] The invention discloses a preparation process of deep flame-retardant leather for high-speed trains and airplanes. The wet-blue leather is used as a raw material, and after pickling, retanning, softening, filling, fatliquoring and flame-retardant, the deep flame-retardant leather is finally prepared.

[0022] The pickling is to place the wet blue hides in the drum, add distilled water of 1 times the weight of the wet blue hides and cook for 5 minutes, then naturally cool down to 50°C, add an acidulant, adjust the pH value to 3.5, rotate for 100 minutes, and then Drain the water, then re-add distilled water twice the weight of the wet blue hide, rotate at a constant temperature of 40°C for 20 minutes, and empty the water to obtain the acidified wet blue hide.

[0023] The retanning is to place the acidified wet blue in a drum, add 2 times the water of the wet blue weight, then add 4% retanning agent and 2% degreasing agent of the wet blue weight, and then Raise the tempe...

Embodiment 2

[0035] The invention discloses a preparation process of deep flame-retardant leather for high-speed trains and airplanes. The wet-blue leather is used as a raw material, and after pickling, retanning, softening, filling, fatliquoring and flame-retardant, the deep flame-retardant leather is finally prepared.

[0036] The pickling is to place the wet blue hides in a drum, add distilled water of 1 times the weight of the wet blue hides and boil for 5 minutes, then naturally cool down to 60°C, add an acidulant, adjust the pH value to 3.7, rotate for 120 minutes, and then Drain the water, then re-add distilled water twice the weight of the wet blue hide, rotate at a constant temperature of 40°C for 20 minutes, and empty the water to obtain the acidified wet blue hide.

[0037] The retanning is to place the acidified wet blue in a drum, add 2 times the water of the wet blue weight, then add 4% retanning agent and 2% degreasing agent of the wet blue weight, and then Heat up and stir ...

Embodiment 3

[0049] The invention discloses a preparation process of deep flame-retardant leather for high-speed trains and airplanes. The wet-blue leather is used as a raw material, and after pickling, retanning, softening, filling, fatliquoring and flame-retardant, the deep flame-retardant leather is finally prepared.

[0050]The pickling is to place the wet blue hides in the drum, add distilled water of 1 times the weight of the wet blue hides and boil for 5 minutes, then naturally cool down to 55°C, add an acidulant, adjust the pH value to 3.6, rotate for 110 minutes, and then Drain the water, then re-add distilled water twice the weight of the wet blue hide, rotate at a constant temperature of 40°C for 20 minutes, and empty the water to obtain the acidified wet blue hide.

[0051] The retanning is to place the acidified wet blue in a drum, add 2 times the water of the wet blue weight, then add 4% retanning agent and 2% degreasing agent of the wet blue weight, and then Raise the temper...

Abstract

The invention discloses a preparation process of deep-level flame-retardant leather for high-speed trains and airplanes. The preparation process is characterized by comprising the steps of pickling, retanning, softening, filling, stuffing and flame retarding by taking blue wet leather as a raw material to finally obtain the deep-level flame-retardant leather. By using the flame-retardant leather prepared by using the preparation process, the problems that the leather is flammable and poor in softness are solved; and the prepared leather has high flame retardance and a compact grain surface and is good in softness and excellent in physical and chemical properties.

Description

technical field [0001] The invention belongs to the field of leather production technology, and in particular relates to a preparation technology of deep flame-retardant leather for high-speed trains and airplanes. Background technique [0002] Leather products are widely used in the production of forest fire prevention equipment, hotels, KTV and aircraft, automobile interiors due to their excellent air permeability, water permeability, heat insulation, sweat resistance, aging resistance, wear resistance, scratch resistance and puncture resistance. High-end fields such as decoration and manufacture of office furniture. With the improvement of leather demand and living standards, the softness and flame retardancy of leather used as interior decoration are very high. Contents of the invention [0003] The purpose of the present invention is to provide a preparation process for deep-layer flame-retardant leather for high-speed trains and aircrafts. The flame-retardant leathe...
