The heat dissipation layer 400 is directly contacted with the electronic product, and the heat dissipation layer 400 has good heat dissipation performance, thereby reducing the influence on the heat dissipation performance of the electronic product due to the addition of protective measures for the electronic product, namely, the addition of a shell protective film.

Referring to fig. 1, further, the protective film main body includes a synthetic leather layer 100, a glue layer 200 and a thin film layer 300 which are sequentially stacked, the heat dissipation layer 400 is connected to the thin film layer 300, an area of an orthographic projection of the heat dissipation layer 400 is smaller than an area of an orthographic projection of the thin film layer 300, and an area of an orthographic projection of the glue layer 200 is larger than an area of an orthographic projection of the heat dissipation layer 400.

The case protective film is composed of a synthetic leather layer 100, a glue layer 200, a thin film layer 300, and a heat dissipation layer 400.

The synthetic leather layer 100 is made of a PU material which has the texture of real leather and is durable in combination; the material can be prepared by a dry method or a wet method generally; the dry process of making PU includes coating PU resin onto release paper with different grains, stoving, pasting, adhering with base fabric, stoving and other steps to make the product have the same grains as the release paper, and printing to make the product possess touch, toughness and appearance comparable to leather.

The wet PU leather making process includes covering the fabric fiber cloth with one layer of PU resin, soaking the fabric fiber cloth covered with PU resin in a coagulating tank with water, embossing the PU resin layer with mold with carved pattern, taking out the fabric fiber cloth, washing in water tank to further mature and obtain PU synthetic leather with stereo pattern; the lines of the processed synthetic leather have strong stereoscopic impression, so that the texture of the synthetic leather is more approximate to the natural texture of natural fur.

The thin film layer 300 is mainly used for supporting the synthetic leather layer 100, so the synthetic leather layer 100 has toughness, and when the plastic film is installed, if the plastic film layer 300 is not supported, deformation can occur, and the thin film layer 300 plays a shaping role due to no elasticity, so that the size of the whole shell protective film can not deform.

Generally, the protective film for the shell can be directly adhered to an electronic product, the area of the heat dissipation layer 400 is smaller than that of the thin film layer 300, so that the heat dissipation layer 400 cannot completely cover the thin film layer 300, the PET film of the part which is not covered with the heat dissipation layer 400 is removed, and the adhesive layer 200 is inevitably exposed because the area of the adhesive layer 200 is larger than that of the heat dissipation layer 400, so that the protective film for the shell is adhered to the electronic product through the adhesive layer 200, and the connection between the protective film for the shell and the electronic product is realized.

Generally the thickness of synthetic leather layer 100 is 0.1-0.9mm, the thickness of thin film layer 300 is 10-100um, just glue film 200 is formed by pressure-sensitive removable adhesive, and thin film layer 300 chooses the PET film for use, can also choose polyvinyl chloride, polyethylene, polypropylene, polystyrene and other resin to make the film.
