Embodiment 1
[0025] The present invention provides a method for producing stretch-resistant leather, which includes:
[0026] Prepare the leather, shave it to a thickness of 1.6~1.8 mm, and fill the skin with fullness, grass, softness and hardness.
[0027] Primer coating process: Take 80 parts by mass of water, heat to 10~25 degrees Celsius, add 90-110 parts by mass of water-based discoloring wax, stir for 1~2min, then add 90-110 parts by mass of scorched black wax, stir for 1~2min, Then add 12-40 parts by mass of soft casein, stir for 1~2 min, and then add 30-50 parts by mass of acrylic resin, which is fully dissolved; spread the leather on the conveyor belt of the roller coater, and the drum speed 28 revolutions per second, the conveying speed of the conveyor belt is 0.1 meters per second, and the coating amount is 20-25g / square foot.
[0028] Hang-drying process: Hang-drying at room temperature of 10-30 degrees Celsius for 6 hours;
[0029] Polishing process: Adjust the speed of the leather p...
