Therslipperlastic elastomer protective film and preparation process thereof

Abstract

The invention discloses a therslipperlastic elastomer protective film and a preparation process thereof. The therslipperlastic elastomer protective film comprises a base layer, wherein a composite adhesive layer is arranged on the upper side of the base layer, an anti-scratching layer is arranged on the upper side of the composite adhesive layer, a pressure-sensitive adhesive layer is arranged onthe lower side of the base layer, and an attaching layer is arranged on the lower side of the pressure-sensitive adhesive layer. According to the invention, a TPU film is compounded with a highlight PTE film by adopting a calendering coating technology, so that the technical problems in the aspects of cleanliness, crystal points, flow marks, water ripples and the like of TPU can be solved; and a PET film does not need to be additionally arranged to serve as an optical base material layer in the protective film formed by attaching the TPU film compounded highlight PTE film as a base film, so that the thickness of a PTE material can be effectively reduced, later processing and use are facilitated, and the obtained material has high hardness and high flexibility, has high buffering performance on impact force and can achieve an obvious explosion-proof effect.

Description

technical field [0001] The invention relates to the technical field of protective films, in particular to a thermoplastic elastomer protective film and its technology. Background technique [0002] Thermoplastic elastomer TPE / TPR, also known as artificial rubber or synthetic rubber. Its products not only have the excellent properties of high elasticity, aging resistance and oil resistance of traditional cross-linked vulcanized rubber, but also have the characteristics of convenient processing and wide processing methods of ordinary plastics. It can be produced by injection molding, extrusion, blow molding and other processing methods, and 100% of the corners of the nozzle can be directly used for secondary use after being crushed. It not only simplifies the processing process, but also reduces the processing cost. Therefore, thermoplastic elastomer TPE / TPR material has become the latest material to replace traditional rubber. It is environmentally friendly, non-toxic, comfo...

AI Technical Summary

Problems solved by technology

[0004] The current TPU mold preparation process is prone to problems such as crystal impurities, flow marks, water ripples, and low cleanliness on the surface during the preparation process, which cannot meet the high-definition and high-cleanliness requirements of screen protection. The anti-scratch protective film products currently on the market It can only prevent hard objects from being scratched. If mobile phones and other products slip from your hands, or heavy objects fall on the screen, it cannot effectively protect the screen; the protection effect must be achieved by increasing the thickness of the substrate, but due to the protective film The base material is mainly PET, and the thickness exceeding 100 μm will be particularly hard, which is not conducive to post-processing. At the same time, the hand feeling of customers is not good when using it, and it is easy to scratch the skin. Therefore, those skilled in the art provide a thermoplastic elastomer protective film and Its technology, to solve the problem that raises in the above-mentioned background technology
