DETAILED DESCRIPTION

[0024] The following is a further description of the specific implementation of the present invention in conjunction with the accompanying drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0025] The terms "outside" and "inside" are based on the normal use state of the glass explosion-proof film and are only used to facilitate the description of the present invention and simplify the description. They do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation. Therefore, they cannot be understood as a limitation on the present invention.

[0026] In addition, the terms "first", "second", etc. are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, a feature defined as "first", "second", etc. may explicitly or implicitly include one or more of the features. In the description of the invention of the utility model, unless otherwise specified, the meaning of "plurality" is two or more.

[0027] like Figures 1-2 As shown, the utility model discloses a glass explosion-proof film, comprising an explosion-proof substrate layer 1, an adhesive layer 2, a release film 3 and a dust removal film 4, wherein the explosion-proof substrate layer 1 has a first surface 101 and a second surface 102 along the film thickness; the adhesive layer 2 is arranged on the first surface 101; the release film 3 is arranged on the surface of the adhesive layer 2 away from the explosion-proof substrate layer 1; the dust removal film 4 is arranged on the surface of the release film 3 away from the adhesive layer 2.

[0028] The explosion-proof substrate layer 1 and the dust removal film 4 are respectively arranged on the two surfaces of the release film 3. The dust on the glass surface is removed by the dust removal film 4. When the dust removal film is peeled off, the explosion-proof substrate layer 1 is installed on the glass surface through the adhesive layer 2. Not only the dust on the glass surface is removed in time, the scratches on the explosion-proof substrate layer 1 caused by dust are effectively prevented, and the work efficiency and dust removal effect are improved.

[0029] In order to prevent the adhesive layer and the release film from being delaminated when the dust removal film is peeled off, so as not to reduce the bonding firmness of the explosion-proof substrate layer and the utilization rate of the explosion-proof substrate layer, the release film 3 includes a reinforcing core layer 30 and a light peeling force release layer 32 and a heavy peeling force release layer 31 respectively arranged on the two surfaces of the reinforcing core layer 30, the light peeling force release layer 32 is connected to the dust removal film 4, and the heavy peeling force release layer 31 is connected to the adhesive layer 2. Among them, the light peeling force release layer 32 and the heavy peeling force release layer 31 are prepared by coating and curing a coating liquid mixed with a corresponding silicone oil main agent, an anchoring agent, a cross-linking agent, a catalyst and a solvent. The peeling force of the light peeling force release layer 32 is 3 to 6 grams, and the peeling force of the heavy peeling force release layer 31 is 20 to 30 grams.

[0030] In order to effectively protect the articles from aging and fading caused by ultraviolet radiation and to increase the service life of the explosion-proof substrate layer, the explosion-proof substrate layer 1 includes an anti-ultraviolet layer 10 and a first reinforcing layer 11 and a second reinforcing layer 12 respectively arranged on the two surfaces of the anti-ultraviolet layer 10, and the first reinforcing layer 11 and / or the second reinforcing layer 12 are PET layers or TPU layers. Among them, the anti-ultraviolet layer 10 is an anti-ultraviolet adhesive layer, and the first reinforcing layer 11 and the second reinforcing layer 12 are compounded. PET (polyethylene terephthalate) has good transparency, mechanical strength and weather resistance; while TPU (thermoplastic polyurethane) has high elasticity, wear resistance, tear resistance, hydrolysis resistance and good low-temperature flexibility. The TPU layer improves the elasticity and recovery performance of the glass explosion-proof film, and can enhance the impact resistance of the glass explosion-proof film, especially for occasions that need to withstand large tensile forces or collisions. The PET layer provides high-strength and stable support, maintains the basic shape of the glass explosion-proof film, and ensures its dimensional stability for long-term use. The provision of the TPU layer improves the softness and plasticity of the glass explosion-proof film, enabling it to perform excellently when covering complex curved surfaces. Therefore, the composite glass explosion-proof film is more suitable for use on irregular curved glass.

[0031] The second surface 102 of the explosion-proof substrate layer 1 is provided with a scratch-resistant coating 100. The provision of the scratch-resistant coating 100 can increase the hardness and wear resistance of the surface of the glass explosion-proof film, so that it is not easily scratched or worn by hard objects such as keys, nails, sand and dust during daily use, thereby extending its service life; in order to maintain clarity, even if it is slightly scratched, it can effectively protect the internal structure of the glass explosion-proof film from being damaged, ensuring that the glass can still maintain good optical transparency after the film is applied, and does not affect the indoor and outdoor observation field; in order to improve safety, for the glass explosion-proof film of the car, the scratch-resistant performance can also ensure that in an emergency, such as when a collision occurs, the film body will not produce a large number of scratches or cracks due to external force impact, maintain integrity, and then continue to play the role of preventing glass splashing and providing safety protection; it can achieve the effect of easy maintenance and cleaning, and there is no need to worry too much about easily damaging the surface of the film when wiping the glass, and it will not damage the function of the explosion-proof film while keeping it clean.

[0032] In order to optimize the structure of the dust removal film, realize the adsorption of dust by electrostatics, and reduce scratches on the glass surface, the dust removal film 4 includes an outer layer 43, an elastic core layer 42 and an inner layer 41, wherein the inner layer 41 is a polyethylene layer, and the inner layer 41 is connected to the light peeling force release layer 32. The polyethylene layer is thin and has good adsorption performance, and can remove dust from the glass surface without using an adhesive. The setting of the elastic core layer 42 can make the dust removal film 4 have good elasticity, thereby preventing the dust removal film from being torn during use and improving its service life. Further, the elastic core layer 42 is a PDMS silicone layer or a thermoplastic elastic layer. PDMS (polydimethylsiloxane) silicone film has excellent elasticity. It is a typical polymer elastomer material with the characteristics of flexibility, transparency, chemical corrosion resistance and biocompatibility. In different applications, the PDMS film can withstand deformation and return to its original state. This is due to its cross-linked network structure, which enables the material to maintain elasticity and resilience after being subjected to force. Thermoplastic elastomer (TPE) film also has elasticity.

[0033] When the glass explosion-proof film is rolled up, the outer layer 43 of the dust removal film 4 is in contact with the scratch-resistant coating 100. In order to improve the anti-fouling property of the dust removal film and maintain the cleanliness of the surface of the scratch-resistant coating, the outer layer 43 is a metallocene polyethylene layer.

[0034] The reinforcing core layer 30 is a polyethylene terephthalate layer. Polyethylene terephthalate (PET) has a low thermal shrinkage rate and hygroscopicity, so it maintains a stable size under different temperature and humidity conditions, and maintains the size of the film surface and the clear glass surface; the PET substrate is also convenient for coating silicone oil or other release agents on one or both sides thereof to form a uniform release layer with good peelability.

[0035] In order to prevent the dust from being adsorbed by static electricity when the dust removal film and the explosion-proof substrate layer are peeled off, resulting in the dust removal effect of the dust removal film being reduced and the adhesive performance of the adhesive layer of the explosion-proof substrate layer being reduced, an antistatic layer 33 is provided between the reinforcing core layer 30 and the light peeling force release layer 32, and / or between the reinforcing core layer 30 and the heavy peeling force release layer 31. Further, the antistatic layer 33 is a polythiophene conductive coating.

[0036] The thickness of the explosion-proof substrate layer 1 is 100-150 μm, the thickness of the adhesive layer 2 is 10-20 μm, the thickness of the release film 3 is 30-50 μm, the thickness of the dust removal film is 20-40 μm, and the thickness of the scratch-resistant coating 100 is 2-5 μm.

[0039] The release film 3 includes a reinforcing core layer 30 and a light release layer 32 and a heavy release layer 31 respectively disposed on the two surfaces of the reinforcing core layer 30. The light release layer 32 is connected to the dust removal film 4, and the heavy release layer 31 is connected to the adhesive layer 2. An antistatic layer 33 is disposed between the reinforcing core layer 30 and the light release layer 32.

[0040] The explosion-proof base material layer 1 comprises an anti-ultraviolet layer 10 and a first reinforcing layer 11 and a second reinforcing layer 12 which are respectively arranged on two surfaces of the anti-ultraviolet layer 10 . Both the first reinforcing layer 11 and the second reinforcing layer 12 are PET layers.

[0041] The dust removal film 4 includes an outer layer 43, an elastic core layer 42 and an inner layer 41. The inner layer 41 is a polyethylene layer connected to the light peeling force release layer 32. The elastic core layer 42 is a PDMS silicone layer, and the outer layer 43 is a metallocene polyethylene layer.

[0042] Example 2

[0043] like Figure 2 As shown, Example 2 is based on Example 1, except that the explosion-proof substrate layer 1 includes an anti-ultraviolet layer 10 and a first reinforcing layer 11 and a second reinforcing layer 12 respectively disposed on two surfaces of the anti-ultraviolet layer 10, the first reinforcing layer 11 is a PET layer, the second reinforcing layer 12 is a TPU layer, and the second reinforcing layer 12 is connected to the scratch-resistant coating 100. The glass explosion-proof film of Example 2 is not only suitable for flat glass, but also for irregular curved glass.

It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
