The production method mainly comprises the following steps: raw material crushing, melting and extruding; base film cooling and extrusion forming; gluing and drying; hot melting and double layer base film lamination; and cooling and rolling.

Description

Technical field [0001] The present invention relates to the field of color production membrane production, and is specifically a TPU color film production device and a production method. Background technique [0002] The TPU is a thermoplastic polyurethane elastomer plastic, which can be soft and re-plastic with a certain heat, which has good wear resistance, and also conforms to environmental requirements, through excellent physical properties and chemical performance, TPU in one The rubber and plastic products are standing out, and they are widely used by all walks of life, and they are attached to the surface of various items, which act as a wear-resistant layer. [0003] In order to improve the aesthetics, the TPU hot melt film is added to the color master, so that each of the produced colors is different, and some color films are monolayer films. As the TPU membrane is used, the single layer is increased. The color film has not been able to meet the personalized demand of th...

Problems solved by technology

[0003] In order to improve the aesthetics, TPU hot melt adhesive film is produced by adding color masterbatch to produce TPU color films with different colors. Some color films are single-layer films. The color film can no longer meet the individual needs of customers, and the color part of the multi-layer color film is also realized in a single-layer film. Some may have colors in multiple layers, but the colors of each layer are the same, and there is no sense of dynamics.

In addition, when the TPU hot melt adhesive film is formed, due to its high viscosity, calendering is easy to make the molten adhesive film stick to the forming roller, and it is necessary to install a release paper, which will increase the cost of the enterprise, while the stretch forming is easy to make the molten adhesive film stick to the forming roller. The film is partially torn, reducing the yield
