Embodiment 1

[0022] A kind of preparation method of thermoplastic elastomer (TPU) crystal leather, such as figure 1 As shown, follow the steps below:

[0023] Apply the color paste evenly on the Beisi cloth at 80°C, and dry and solidify at 100°C. Then 0.8 parts by weight of thermoplastic elastomer POE and 0.2 parts by weight of ethylene octene polymer elastomer were mixed at 90° C., and then bonded to the above-mentioned cured Beisi cloth under a pressure of 0.3 MPa.

[0024] Mix 0.9 parts by weight of thermoplastic elastomer TPU and 0.1 parts by weight of environmentally friendly toner, melt at 200°C, bond with the above-mentioned adhesive-treated Beisi cloth under a pressure of 0.5 MPa, and cool. Then, under a pressure of 0.2MPa, the product is embossed through a textured roller or textured release paper to obtain a crystal leather with high transparency and three-dimensional effect.

Embodiment 2

[0026] A kind of preparation method of thermoplastic elastomer (TPU) crystal leather, such as figure 1 As shown, follow the steps below:

[0027] Apply the color paste evenly on the Beisi cloth at 90°C, and dry and solidify at 110°C. Then, 0.7 parts by weight of thermoplastic elastomer TPU and 0.3 parts by weight of ethylene octene polymer elastomer were mixed at 95° C., and then bonded to the above-mentioned cured Beisi cloth under a pressure of 0.2 MPa.

[0028] Mix 0.8 parts by weight of thermoplastic elastomer TPU and 0.2 parts by weight of environmentally friendly toner evenly, melt at 150°C, bond with the above-mentioned adhesive-treated Beisi cloth under 0.4 MPa pressure, and cool. Then, under a pressure of 0.4MPa, the product is embossed through a textured roller or textured release paper to obtain a crystal leather with high transparency and three-dimensional effect.

Embodiment 3

[0030] A kind of preparation method of thermoplastic elastomer (TPU) crystal leather, such as figure 1 As shown, follow the steps below:

[0031] Apply the color paste evenly on the Beisi cloth at 100°C, and dry and solidify at 120°C. Then, 0.9 parts by weight of thermoplastic elastomer TPU and 0.1 part by weight of ethylene octene polymer elastomer were mixed at 120° C., and then bonded to the above-mentioned cured Beisi cloth under a pressure of 0.2 MPa.

[0032] Mix 0.8 parts by weight of thermoplastic elastomer TPU and 0.2 parts by weight of environmentally friendly toner, melt at 350°C, bond with the above-mentioned adhesive-treated Beisi cloth under a pressure of 0.8 MPa, and cool. Then, under a pressure of 0.8MPa, the product is embossed through a textured roller or textured release paper to obtain a crystal leather with high transparency and three-dimensional effect.

Abstract

The invention provides a preparation method of thermoplastic elastomer crystal leather, which includes the following steps: coating color paste on a substrate under 60-120 DEG C, and drying and curing under 100-120 DEG C; heating 0.7-1 part by weight of thermoplastic elastomer and 0.1-0.5 part by weight of modifier to 100-200 DEG C to be mixed and melted, and then bonding the mixture with the product obtained in the first step; mixing 0.8-1 part by weight of thermoplastic elastomer and 0.1-0.5 part by weight of coloring agent to be even, melting under 150-350 DEG C, then bonding the mixture with the product obtained in the second step under the pressure of 0.2-0.8MPa, and cooling to obtain composite material; and pressing the composite material under the pressure of 0.2-0.8MPa to obtain thermoplastic elastomer crystal leather. The preparation method of the thermoplastic elastomer crystal leather provided by the invention does not cause pollution to the environment, and the crystal leather products produced through the method are of lucency and are wear resistant and low temperature resistant.

Description

technical field [0001] The invention relates to a preparation method of synthetic leather, in particular to a preparation method of thermoplastic elastomer (TPU) crystal leather. Background technique [0002] With the enhancement of people's consumption awareness, higher requirements have been raised for the synthetic leather industry. In addition to the requirements for pattern varieties, it is more important to pay attention to environmental protection awareness. [0003] The current method of producing crystal leather is to grind the bass, dye it, and then veneer it with special crystal leather raw materials. The main material used in the production process is polyvinyl chloride (PVC) polyurethane (PU). They emit a large amount of phthalate gas and waste water containing dimethylformamide (DMF) during the production process, which are discharged into nature. Although people are managing it, there are still some harmful substances that are discharged into the environment...
