Embodiment Construction

[0015] The present invention will be further described in detail below in conjunction with the embodiments, so that those skilled in the art can implement it with reference to the description.

[0016] This case lists an embodiment of the self-venting protective film, which includes a venting layer and a PET substrate layer;

[0017] Wherein, the exhaust layer includes the following materials by weight:

[0018]

[0019] The exhaust layer is mainly composed of polydimethylsiloxane, and aminosiloxane is used to synergistically improve the auto-foaming ability of polydimethylsiloxane; hexamethyldisiloxane is used to improve the The cohesion of the alkane system can reduce the residual rate of the exhaust layer and increase the number of repeated tearing and pasting of the exhaust layer; the silane-modified polyether resin can improve the water repellency of polydimethylsiloxane to reduce the impact of the exhaust layer on The absorption rate of moisture in the air, so that t...

Abstract

The invention discloses an automatic exhaust type protective film. The automatic exhaust type protective film comprises an exhaust layer and a PET (polyethylene terephthalate) substrate layer. The exhaust layer is prepared from, by weight, 100 parts of polydimethylsiloxane, 12-14 parts of amino siloxane, 2-3 parts of hexamethyldisiloxane and 2-3 parts of silane modified polyether resin. By modification of an exhaust layer component of an existing automatic exhaust type protective film, automatic debubbling performance of the exhaust layer is improved, and the exhaust layer is still excellent in debubbling performance even after repeated tearing and sticking, so that fitting difficulty of the protective film is lowered; light transmittance, adhesion strength and weather resistance of the protective film are guaranteed, and residual adhesive ratio is effectively decreased. The automatic exhaust type protective film is applicable to fields of electronic screens and the like.

Description

technical field [0001] The invention relates to an automatic exhaust type protective film. Background technique [0002] With the rapid development of products such as smart phones and tablet computers, in recent years, accessories in these fields have also formed a huge industrial chain, and electronic screen protectors for these products are one of the typical ones. There are many types of screen protectors on the market, but they are generally transparent film materials that rely on static electricity or adhesives to adhere to the screen. The disadvantages of this type of product are easy to fall off, foam, short life, not scratch-resistant, not shock-resistant, not easy to stick, etc. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the invention provides an automatic exhaust type protective film. [0004] Technical scheme of the present invention is summarized as follows: [0005] A self-venting type protective film, which includes a ...
