Embodiment 1
[0022] A kind of manufacturing method of zero-emission full-environmental protection synthetic leather, as attached figure 1 shown. Follow the steps below in order:
[0023] A. Coat water-based acrylic on one side of the base fabric with non-woven fabric at 100°C, and dry and harden at 120°C;
[0024] B. Heat 0.7 parts by weight of thermoplastic elastomer TPE and 0.3 parts by weight of modifier through an extruder to melt and mix them at 90°C. Then through the die head and the base cloth treated in step A, bond under the pressure of 0.5 MPa to make a strong base material.
[0025] C. Mix 1 part by weight of thermoplastic elastomer TPE, 0.2 part by weight of color masterbatch, and 0.8 part by weight of silicone oil evenly. After being heated by an extruder at 100°C and melted, it is extruded from a die through a roller with texture. compound under pressure. Made a preliminary synthetic leather.
[0026] D. The preliminary synthetic leather is strengthened in 30°C water, an...
Embodiment 2
[0030] A kind of manufacturing method of zero-emission full-environmental protection synthetic leather, as attached figure 1 shown. Follow the steps below in order:
[0031] A. Apply water-based acrylic to one side of the base fabric with nylon fabric at 160°C, and dry and harden at 150°C;
[0032] B. Heat 1 weight part of thermoplastic elastomer TPE and 0.5 weight part of modifier through an extruder to melt and mix them at 350°C. Then through the die head and the base cloth treated in step A, bond under a pressure of 0.8 MPa to form a strong base material.
[0033] C. Mix 1 part by weight of thermoplastic elastomer TPE, 0.2 part by weight of color masterbatch, and 0.8 part by weight of polyethylene, heat and melt at 350 °C in an extruder, and then extrude from a die through a roller with texture, at 0.5 Composite under MPa pressure. Made a preliminary synthetic leather.
[0034] D. The preliminary synthetic leather is strengthened in 50°C water, and dried to remove wate...
Embodiment 3
[0037] A kind of manufacturing method of zero-emission full-environmental protection synthetic leather, as attached figure 1 shown. Follow the steps below in order:
[0038] A. Apply water-based EVA glue on one side of the polyester woven fabric as the base fabric at 200°C, and dry and harden at 100°C;
[0039] B. Melt and mix 0.6 parts by weight of thermoplastic polyurethane elastomer TPU and 0.2 parts by weight of modifier through an extruder at 80°C, and then pass through the die and the base cloth treated in step A under a pressure of 0.3MPa. Synthesized into a strong base material.
[0040] C. Mix 0.8 parts by weight of thermoplastic elastomer TPE, 3 parts by weight of toner, and 0.8 parts by weight of silicone oil evenly, heat and melt at 260°C in an extruder, extrude through a die, and press with a roller with texture at a pressure of 0.3 MPa Composite below. Made into preliminary synthetic leather.
[0041] D. The preliminary synthetic leather is strengthened in 3...
