Problems solved by technology

[0002] According to the purpose, the protective film can be divided into product protective film, car protective film, household protective film, food preservation film, etc. With the development of the electronics and communication industries, various mobile phones, computers, and game consoles have become an indispensable part of people's lives. However, most of the mobile phones, tablet computers, medical instruments and automobiles on the market use liquid crystal materials as display panels. With the extension of use time, the liquid crystal panels are easy to turn yellow and dirty, which will affect the service life of the liquid crystal panels. Therefore, it is used for protection As a peripheral industry, the protective film of liquid crystal panels of mobile phones, tablet computers, medical instruments and automobiles has become more and more widely used and researched
[0003] At present, there are more and more high-value products such as electronic products and automobiles, and they are becoming more and more popular. The protection of such products is also indispensable, but the protective films currently on the market are all developed and used for a certain product. And the design with backing paper is commonly used. After use, the backing paper is discarded, which is not environmentally friendly. At the same time, in the process of use, the performance of anti-scratch and waterproof is average. For this reason, we propose a non-glue-feeling Heat-shrinkable heat-adhesive general-purpose high-transparency protective film preparation method to solve the above problems

Abstract

The invention discloses a preparation method of an adhesive-feeling-free heat-shrinkable heat-sticking universal high-transmittance protective film, and relates to the technical field of protective films. The preparation method comprises the following steps: S1, weighing the raw materials in parts by weight: 15-20 parts of tackifying resin, 25-35 parts of an acrylate pressure-sensitive adhesive, 3-5 parts of an auxiliary agent, 12-15 parts of an inorganic filler, 1-3 parts of a coupling agent, 20-25 parts of a curing agent and 10-15 parts of a solvent. According to the preparation method of the adhesive-feeling-free heat-shrinkable heat-sticking universal high-transmittance protective film, the prepared protective film adopts a heat shrinkage technology, the protective film can shrink and deform at the temperature of 80 DEG C or above, the surface of a protected product is covered with the film firstly, the film is heated to be shrunk, then the film can be well attached to the protected product after being tightened, universal protection is achieved, and no adhesive feeling exists; the glue is hot viscose water, does not have viscidity at normal temperature, and only has viscidity after being heated to 90 DEG C; and the protective film does not need to be coated with backing paper in the storage and transportation processes.
