[0020] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.
[0021] Some embodiments of the present invention are described below in conjunction with the accompanying drawings.
[0022] Embodiment 1:
[0023] Combination Figure 1-3 As shown, this embodiment provides a high-adsorption PET protective film, including: a main body module 100.
[0024] Among them, the main body module 100 includes a PET base layer 110, a silicone adsorption layer 120 fixed at the bottom of the PET base layer 110, an adhesive layer 130 arranged at the bottom of the silicone adsorption layer 120, a peeling layer 140 arranged at the bottom of the adhesive layer 130, a ceramic coating layer 150 fixed on the upper surface of the PET base layer 110, a polyester layer 160 fixed on the upper surface of the ceramic coating layer 150, a wear-resistant layer 170 fixed on the top of the polyester layer 160, and an SR coating layer 180 wrapped around the outside of the PET base layer 110, the ceramic coating layer 150 and the polyester layer 160.
[0025] The thickness of the PET base layer 110 is 0.1MM, and a silicone adsorption layer 120 is fixed on its lower surface for adsorption on the surface of the protected object. A plurality of conical holes 121 are arranged in an array on the lower surface of the silicone adsorption layer 120, and an adhesive layer 130 is arranged on the lower surface of the silicone adsorption layer 120 for adhering and fixing the silicone adsorption layer 120 to the protected object. During adhesion, it is only necessary to press the PET base layer 110, and a portion of the adhesive layer 130 enters the conical hole 121, thereby increasing the bonding surface between the adhesive layer 130 and the silicone adsorption layer 120 and improving the bonding stability. After the adhesive layer 130 is cured, it can be embedded in the conical hole 121, thereby making the bonding between the adhesive layer 130 and the silicone adsorption layer 120 more firm, thereby avoiding the phenomenon of the PET protective film falling off.
[0026] The ceramic coating 150 is bonded to the upper surface of the PET base layer 110 and has a thickness of 0.1MM. The ceramic powder is heated to a high temperature state and then sprayed onto the PET base layer 110 through a spray gun to form a uniform coating, which can effectively improve the hardness and corrosion resistance of the PET base layer 110.
[0027] The polyester layer 160 is transparent polyester, attached to the upper surface of the ceramic coating 150, with a thickness of 0.15MM, which can play a certain role in blocking impact and reducing external damage.
[0028] The wear-resistant layer 170 is bonded to the upper surface of the polyester layer 160 and is a transparent highly scratch-resistant acrylic resin. It has very tough and scratch-resistant properties and can effectively improve the wear resistance of the PET protective film.
[0029] The top of the SR coating layer 180 is fixed to the lower surface of the wear-resistant layer 170, and the bottom of the SR coating layer 180 is fixed to the upper surface of the silicone adsorption layer 120, which performs a sealing function on the outside of the PET base layer 110, the ceramic coating layer 150 and the polyester layer 160 to prevent the side from delamination.
[0030] The working principle and use process of the utility model are as follows: when pasting the protective film, clean the surface of the protected object, tear off the peeling layer 140, expose the adhesive layer 130, stick the adhesive layer 130 to the surface of the protected object and press the protective film. Under the action of pressure, a part of the adhesive layer 130 enters the tapered hole 121, which increases the bonding surface between the adhesive layer 130 and the silicone adsorption layer 120 and improves the bonding stability. At the same time, after the adhesive layer 130 is cured, it can be embedded in the tapered hole 121, so that the bonding between the adhesive layer 130 and the silicone adsorption layer 120 is tighter. In addition, the ceramic coating 150 increases the strength of the PET base film, the polyester layer 160 can buffer the PET protective film when it is impacted by the outside world, and the wear-resistant layer 170 can effectively improve the wear resistance and avoid scratches.
[0031] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
