Problems solved by technology

However, due to the fact that some toxic auxiliary materials such as plasticizers and anti-aging agents are often added to PVC in the manufacturing process to enhance its heat resistance, toughness, ductility, etc., there are certain defects in its application.
For example, PVC products often emit a unique odor due to the volatilization of plasticizers. When using PVC products, they are also easy to come into direct contact with plasticizers, causing great harm to the human body.
In addition, its elasticity, toughness, wear resistance, cold resistance and other properties are still not enough to manufacture some high-demand products, and it is also easy to crack and break, and the cost is relatively high when used in bags, building materials, shoe materials and other products

Embodiment 1

[0034] Embodiment 1, a PVC film with a TPU film in the present invention, which includes a PVC film layer, and the PVC film layer is pasted with a TPU layer by glue or hot pressing. Further, the TPU layer is provided with an embossed or printed layer, which can emboss or print characters and patterns. Further, the PVC film layer is provided with an embossed or printed layer, which can be embossed or printed with characters and patterns.

Embodiment 2

[0035] Embodiment two, a kind of production technology of adding the PVC film of TPU film described in above-mentioned embodiment one, comprises the following steps:

[0036] In step A, the rolls of PVC film material 20 and TPU material 10 are fed by feed rollers respectively. If no glue is added between the PVC film material 20 and TPU material 10, then enter step B. The production schematic diagram is as follows figure 1 Shown; If glue is added between PVC film material 20 and TPU material 10, then enter step C, glue 4 can stick to TPU material 10 first, also can stick to PVC film material 20 first, its production schematic diagram is as follows figure 2 shown;

[0037] Step B, heat and pressurize the PVC film material 20 and the TPU material 10, so that the PVC film material 20 and the TPU material 10 are heat-pressed into one, and enter step D;

[0038] Step C, pressurize the PVC film material 20 and the TPU material 10, or heat and pressurize the PVC film material 20 an...

Abstract

The invention relates to the technical field of a PVC (polyvinyl chloride) product and production process thereof, particularly to a PVC film or PVC artificial leather coated with a TPU (thermoplastic polyurethane) film and production process thereof. The PVC film coated with the TPU film comprises a PVC film layer on which a TPU layer is attached through glue or the manner of hot pressing. The PVC artificial leather coated with the TPU film comprises a PVC artificial leather layer on which is a TPU layer is attached through glue or the manner of hot pressing. According to the invention, the harm of the PVC product to people can be greatly reduced and the properties of elasticity, tenacity, wear resistance and cold resistance of the PVC product are improved; the PVC product is not easy to crack and fracture; and the cost for making cases, building materials and shoe materials can also be greatly reduced.

Description

Technical field: [0001] The invention relates to the technical field of PVC products and its production technology, in particular to a PVC film or PVC artificial leather with a TPU film and its production technology. Background technique: [0002] PVC (polyvinyl chloride) products can be seen everywhere in our daily life. Because of its good processing performance and low manufacturing cost, PVC is widely used to make various imitation leather, bags, shoes and hats, building materials, sports products, toys, etc. However, due to the fact that some toxic auxiliary materials such as plasticizers and anti-aging agents are often added to PVC in the manufacturing process to enhance its heat resistance, toughness, ductility, etc., there are certain defects in its application. For example, PVC products often emit a peculiar smell due to the volatilization of plasticizers. When using PVC products, they are also easy to come into direct contact with plasticizers, causing great harm ...
