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.

Abstract

The invention relates to a production method of zero-emission and full-environment-friendly synthetic leather. The production method comprises the following steps of: coating an aqueous adhesive on a surface of a base fabric at a temperature of 100-200 DEG C, and drying and hardening the basic fabric at a temperature of 100-150 DEG C; heating 0.5-1 part by weight of thermoplastic polymer elastomer and 0.1-0.5 parts by weight of modifying agent to 80-350 DEG C for fusion and mixing, and pressing to adhere the mixture to the treated base fabric so as produce a substrate; and adding 0.2-3 parts by weight of colorant into 0.8-1 part by weight of thermoplastic polymer elastomer, mixing the mixture, heating the mixture to 100-350 DEG C for complete fusion, compositing the mixture with the substrate, and pressing and completely cooling the substrate. Compared with the prior art, the production method cannot result in any pollution in production, and is an environment-friendly and ideal synthetic leather producing method. By adoption of the production method provided by the invention, plenty of energy sources and labor forces can be saved. Products produced by using the production method have the characteristics of unique visual and handfeeling effect, wear resistance, skid resistance and low-temperature performance.

Description

technical field [0001] The invention relates to a method for manufacturing zero-emission all-environmental protection synthetic leather, which belongs to the field of synthetic leather manufacture. Background technique [0002] Along with the demand of people's life and the protection to natural animals, the imitation leather products of various patterns and varieties appear in a large number on the market, and these products are mainly artificial leather and synthetic leather. The leather produced with PVC resin (polyvinyl chloride) plus plasticizer as raw material is artificial leather. The leather produced with PU resin (polyurethane plus 70% dimethylformamide solution) is synthetic leather. [0003] In the prior art, PVC and a large amount of plasticizers and additives are used in the production process of artificial leather, and a large amount of phthalate gases harmful to human body are generated in the production process and discharged into the atmosphere. Synthetic...
