Abstract

The utility model provides a waterproof cell phone protective film. The waterproof cell phone protective film comprises an upper release film, a protective film main body and a lower release film, wherein the protective film main body is composed of a nano anti-scraping coating, a dissipation layer, an absorption layer and a silica gel sticking layer; the size of the cell phone protective film is the same as that of a cell phone panel so that the cell phone protective film can completely cover the cell phone panel; corresponding small holes are formed in positions of loudspeaking holes and keys respectively; the small holes are trapezoidal and are narrow in upper part and wide in lower part. The protective film main body is made of a TPU (Thermoplastic Polyurethane) material; the TPU high molecular material has a special linear molecular structure so that the waterproof cell phone protective film has the very high tension; when the waterproof cell phone protective film is impacted by an external force, the external force can be dispersed and absorbed rapidly; after the external force is removed, the waterproof cell phone protective film can be recovered rapidly under the effect of an elastic force so as to effectively relieve external impact and enable a screen not to be cracked when suffering from high-strength impact and collision; the possibility of cracking of the screen due to the external force is reduced; the design of the small holes with the narrow upper part and the wide lower part has the effect of amplifying the volume and can also prevent a liquid including oil stain, water and the like from immersing into a cell phone from the loudspeaking holes and the keys.

Description

A kind of safeguard film for cellular phone of waterproof

Technical field

The utility model relates to a kind of safeguard film for cellular phone, especially a kind of waterproof mobile phone diaphragm with anti-high-strength impact and collision.

Background technology

Development along with electronics technology; great majority are also more and more higher with the scientific and technological content of the electronic product of screen; some is the electronic product that adopts the LCD screen formula; some is the electronic product that is provided with touch-screen on LCD screen; people are subject to extraneous pollution or scratch for screen is not allowed; substantially can layer protecting film be set on screen, so that screen is not easy contaminated or scratch under the protection of diaphragm.although yet existing diaphragm has played the effect of protection screen, can not very strong due to the hardness of itself, impelling diaphragm itself to be easy to can be by the scratch of extraneous institute, thereby affect people's visual effect, and people can change the diaphragm that leaves scratch for the content that can see clearly on screen, can making like this people change diaphragm on screen, some is frequent, the impact that causes due to External Force Acting in addition and collision meeting cause very major injury to the LCD screen touch-screen of electronic product, serious even need to change screen, and it is higher to change the screen cost, existing screen protection film-strength is not also very large, be not enough to resist larger external impact and collision.A kind of tempered glass diaphragm has also appearred in recent years; this diaphragm has higher hardness; can resist certain impact and collision; yet this diaphragm is bent and is disturbed intensity difference, and well the thickness of waterproof, particularly 0.4T is slightly aobvious abundant; and general screen protecting film; safeguard film for cellular phone particularly, its protective position just is confined to screen this part, can not provide shock resistance and screen protection to whole mobile phone faceplate.

The utility model content

The defect that exists in order to solve prior art, provide a kind of waterproof mobile phone diaphragm with shock resistance and collision.

To achieve these goals, the technical solution adopted in the utility model is:

A kind of safeguard film for cellular phone of waterproof, comprise fractal film, diaphragm main body and lower fractal film, and described fractal film is distributed in diaphragm main body upper surface and lower surface, is used for making the diaphragm main body keep before use cleaning to preserve from;

As improvement of the present utility model, described diaphragm main body consists of the anti-scraping coating of nanometer, dissipate layer, absorbed layer and silica gel adhesive layer, and described nanometer prevents that scraping coating, dissipation layer, absorbed layer consist of TPU thermoplastic polyurethane elastomer macromolecule composite; Described safeguard film for cellular phone size and mobile phone faceplate consistent size, can be fitted on mobile phone faceplate fully.

Further, the safeguard film for cellular phone of described waterproof also is provided with corresponding aperture in the position of loud-speaker opening and button, and described aperture adopts laser to bore a hole, and aperture is up-narrow and down-wide ladder shape, and leptoprosopy up, fit with mobile phone faceplate by wide facing down.

The safeguard film for cellular phone of above-mentioned a kind of waterproof, the anti-scraping coating of described nanometer is positioned at diaphragm main body outer surface, and described dissipation layer is positioned at the anti-scraping coating of nanometer below, and described absorbed layer is positioned at the layer below of dissipating, and described silica gel adhesive layer is positioned at the absorbed layer below.

The safeguard film for cellular phone of above-mentioned a kind of waterproof, described diaphragm main body are the composite bed that a kind of thermoplastic polyurethane elastomer macromolecule composite forms.

The safeguard film for cellular phone of above-mentioned a kind of waterproof, described thermoplastic polyurethane elastomer macromolecule composite hot strength is high, and percentage elongation is large; tearing strength is high; solid surface energy is high, has splendid elasticity, hardness, percentage elongation, surface tension, and water proofing property, impact resistance and damping performance are outstanding.

the beneficial effects of the utility model are: this waterproof mobile phone diaphragm size is consistent with mobile phone faceplate, can be mobile phone faceplate more fully protection is provided, also be provided with aperture at loudspeaker and button correspondence position, sound can spread out of by aperture, the effect that volume is amplified has been played in the up-narrow and down-wide design of aperture, while is in conjunction with the surface tension of TPU polymer composite, can play good waterproof action, main body has adopted the TPU material, and the TPU macromolecular material has ultra-high tension because there is the special linearity molecular structure of physical crosslinking in it, can very fast external force be disperseed to absorb when being subject to external impacts, after removing, external force can restore rapidly under the elastic force effect, effectively alleviated external impact, allow screen be unlikely to break when the impact of bearing high strength and collision, reduced the probability that screen breaks because of external force, provide powerful protection to screen.
