Description

Technical Field

[0001] The utility model relates to the field of mobile phone protective films, in particular to a glass tempered film for blocking infrared heat energy. Background Art

[0002] Mobile phone film, also known as mobile phone beauty film and mobile phone protective film, is a kind of cold-mounted film that can be used to decorate the surface of mobile phone body, screen and other tangible objects. There are many types of mobile phone film, which is an important accessory of mobile phone.

[0003] However, the prior art has the following defects:

[0004] Mobile phones are used more and more outdoors. Navigation, games, video communications, etc. will generate heat for the phone. When used outdoors, the phone will be exposed to the heat from the sun, causing the phone's temperature to rise rapidly and become unusable. However, the mobile phone protective film on the market has a simple structure and does not have good heat insulation properties, making the phone prone to high-temperature damage when exposed to sunlight. Utility Model Content

[0005] The utility model aims to provide a tempered glass film for blocking infrared heat energy, so as to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a glass tempered film for blocking infrared heat energy, comprising a PET release film and a glass tempered film body, the glass tempered film body comprising a PET thermal insulation base layer and a PET base layer, the PET thermal insulation base layer comprising a polyester polymer substrate PET layer, the bottom of the polyester polymer substrate PET layer is sequentially provided with an antioxidant isolation layer, a wear-resistant coating layer, a metal thermal insulation film layer and an anti-ultraviolet isolation layer.

[0007] The above technical solution is adopted. The PET thermal insulation base layer is composed of an antioxidant isolation layer, a wear-resistant coating layer, a metal thermal insulation film layer and an anti-ultraviolet isolation layer, which can effectively filter infrared heat energy emitted in the infrared band (700-2500nm).

[0008] The material of the polyester polymer substrate PET layer is polyethylene, the anti-oxidation isolation layer is a thick polyethylene plastic film, and the polyester polymer substrate PET layer and the anti-oxidation isolation layer are bonded by AB glue.

[0009] By adopting the above technical solution, the polyethylene in this solution has a good heat insulation effect, and the anti-oxidation isolation layer can prevent the polyester polymer substrate PET layer from being damaged by oxidation. The two are bonded by AB glue, and the connection is tight to prevent falling off.

[0010] Both sides of the wear-resistant coating layer are coated with small-particle wear-resistant ceramic coating, and a heat-insulating reflective film is arranged in the metal heat-insulating adhesive film layer, and both sides of the heat-insulating reflective film are coated with glue.

[0011] The above technical scheme is adopted. The wear-resistant ceramic coating of the scheme can prevent the tempered film from being damaged by friction. The heat-insulating reflective film can reflect infrared heat energy, ensuring that the glass tempered film has the function of heat insulation and blocking infrared heat energy. There is transparent glue on both sides of the heat-insulating reflective film, which is convenient for bonding and installing the heat-insulating reflective film with other structures.

[0012] A transparent substrate is arranged inside the anti-ultraviolet isolation layer, anti-UV material is evenly distributed on both sides of the transparent substrate, and glue is coated on both sides of the transparent substrate.

[0013] By adopting the above technical solution, the anti-UV material of the solution can resist ultraviolet rays, and strong ultraviolet rays hardly absorb visible light. It is the preferred ultraviolet absorber for colorless, transparent and colored products; it is non-flammable, non-corrosive and has good storage stability.

[0014] A first OCA layer and a second OCA layer are respectively provided on both sides of the PET thermal insulation base layer, and the materials of the first OCA layer and the second OCA layer are both acrylic. A PET base layer is bonded to one side of the PET thermal insulation base layer through the second OCA layer, and the material of the PET base layer is polypropylene.

[0015] The above technical solution is adopted. The OCA in this solution is an optically transparent adhesive layer used for connecting laminated structures. It has the characteristics of being colorless and transparent, having a light transmittance of more than 90%, having good bonding strength, being curable at room temperature or medium temperature, and having small curing shrinkage.

[0016] A silicone layer is bonded to the side of the PET base layer away from the PET thermal insulation base layer, and a glass layer is bonded to the other side of the PET thermal insulation base layer through the first OCA layer. The glass layer is made of tempered glass, and a frosted surface is applied to the side of the glass layer away from the first OCA layer. A nano coating is coated on the side of the glass layer away from the first OCA layer to form an AF layer.

[0017] By adopting the above technical solution, the silicone layer of the solution is easy to automatically adsorb on the mobile phone screen, so that the tempered glass film can automatically adsorb and has strong bubble removal functions, is easy to operate, and is convenient for novices to use. The AF layer can reduce the surface tension of the tempered glass film to a minimum, greatly reducing the contact area between dust and the glass surface, making it have strong hydrophobic, oil-resistant and fingerprint-resistant capabilities; so that the video glass panel maintains a smooth and bright effect for a long time.

[0018] A PET release film is bonded to the side of the AF layer away from the glass layer, a semicircular easy-tear handle is provided in the middle of one end of the PET release film, and a plurality of release agents are evenly coated on the side of the PET release film facing the AF layer.

[0019] The PET release film using the above technical solution can protect the surface of the glass tempered film when it is not pasted, preventing dust from entering between the tempered film and the mobile phone screen and affecting the use effect. The easy-tear handle makes it easy to tear off the PET release film.

[0020] Compared with the prior art, the beneficial effects of the utility model are:

[0021] Infrared heat insulation film is a film that can block infrared radiation, and tempered film is a kind of glass that has been strengthened. The strength of tempered film is 5-10 times that of ordinary glass, and it has good explosion-proof performance. Combining infrared heat insulation film with tempered film can take into account both heat insulation and explosion-proof performance. BRIEF DESCRIPTION OF THE DRAWINGS
