Abstract

The invention provides a cold light luminous blister and hot pressing product which comprises a sheet body, a TPU film and a conductive luminous layer, the sheet body is sequentially provided with the TPU film and the conductive luminous layer from bottom to top, and the conductive luminous layer comprises a positive electrode, a luminous layer, an insulating layer, a negative electrode and a protective layer which are sequentially arranged from bottom to top. The preparation method comprises the following steps: S1, selecting a substrate; s2, manufacturing an output film; s3, manufacturing a TPU light-emitting film; s4, printing a pattern; s5, compounding; s6, mold forming; s7, removing leftover materials; and S8, connecting a power supply part. According to the invention, the pattern is more variable, after the flexible two-way stretching TPU film is compounded, a concave-convex surface luminous product can be integrally molded, curved surface light emitting is realized, the yield is high, the cost is reduced, and the product has stronger visual effect, stronger atmosphere and stronger sense of science and technology.

Description

technical field [0001] The invention relates to the technical field of plastic-absorbing and hot-pressed products, in particular to a cold-light-emitting plastic-absorbing and hot-pressed product and a preparation method. Background technique [0002] Blister and hot-pressed products, usually used as clothing, packaging, toys, gifts, advertisements, masks, helmets and other products, with any pattern on the silk screen, uniform texture, TPU film is based on TPU particles, after calendering, casting, Films made by special processes such as blown film and coating. The existing blister and hot-pressed luminescent products on the market are formed first and then sewn or bonded on the basis of the pattern by LED light or guide light or cold light. It seems that the product is rough, the manufacturing process is cumbersome and the cost is high. Now there are also products that use ITO, PET, PVC, PC, and EVA as substrates to emit light, but ITO materials cannot be used for curved s...
