Problems solved by technology

③Although the rainbow illusion film is particularly dazzling, the product laminated with this process has a relatively poor appearance and transparency, and the illusion effect will be greatly reduced, which affects the appearance
[0004] At present, the magic film laminated by TPU uses solvent-based adhesive or hot-melt adhesive (the hot-melt adhesive is dissolved and then dried), which will generate a large amount of VOC during the lamination process, and the lamination process using this process The appearance of the product is relatively poor in transparency, and the illusion effect will be greatly reduced, affecting the appearance, and the fastness of adhesion is relatively poor

Abstract

The invention relates to the field of chemical engineering, in particular to a technology for processing a rainbow multi-color film sheet. The process comprises the following steps: 1, mixing and drying TPU (thermoplastic polyurethane) raw materials; 2, adding the TPU raw materials in the step 1 into casting equipment to make a cast film, wherein screw extrusion temperatures in the casting equipment are as follows: the temperature of a first feeding section is set as 170-185 DEG C; the temperature of a second compression section is set as 180-205 DEG C; the temperature of a third discharging section is set as 185-200 DEG C; the temperature of a die head is set as 180-195 DEG C; 3, bonding the cast film in the step 2 and the upper and lower surfaces of a rainbow film; 4, cooling and rolling. The invention aims to provide a processing technology for processing the rainbow multi-color film sheet capable of realizing direct online lamination and improving the production efficiency. The rainbow multi-color film sheet prepared by the technology has excellent wear resistance, scratch resistance, low-temperature resistance and aging resistance, the experience effect of a user is increased,and economic benefits are increased.

Description

technical field [0001] The invention relates to the field of chemical industry, in particular to a processing technology for rainbow-colored film sheets. Background technique [0002] With the improvement of living standards, people begin to look for some special eye-catching things, some high-end shoes, bags, packaging materials, decorative materials and other products with special decorative effects have entered our sight, especially in recent years, the development of the material field , so that these new materials continue to emerge, such as PET lamination, PVC lamination with colorful effect film or sheet into our line of sight, constantly hitting our eyeballs, but these PET or PVC lamination magic color The film sheet itself is not elastic, the wear resistance is relatively poor, and the adaptability to the high and low temperature environment is also relatively poor, and most of these materials are processed by the post-lamination process, which will emit VOCs in the...
