Shockproof, anti-skidding and antistatic protective film

Abstract

The invention discloses a shockproof, anti-skidding and antistatic protective film. The shockproof, anti-skidding and antistatic protective film comprises a protective layer, a using layer and a releasing layer, wherein the protective layer consists of an optical PET (Polyethylene Terephthalate)film and a low-mucilage-glue layer; the using layer mainly consists of a polyurethane foam layer, an antistatic priming coat, an optical PET film and a middle- and high-mucilage-glue layer; the releasing layer mainly comprises an optical PET releasing membrane; the polyurethane foam layer comprises some or all of waterborne polyurethane, sealed hollow expansion spheres, open air bubbles and fluorescent particles. The shockproof, anti-skidding and antistatic comprehensive protective film prepared by the invention is used for protecting the back of a cell phone; the shockproof function of the PU foam layer provides a certain drop-resistant effect for the cell phone; the flexibility and self-adsorption of the PU foam layer can prevent the cell phone from moving after being stressed when the cell phone is put on an object evenly; fluorescent particles in the PU foam layer can glow at night.

Description

technical field [0001] The invention relates to the field of mobile phone films, in particular to an anti-shock, anti-slip and anti-static protective film. Background technique [0002] With the rapid development of smart phones, the demand for mobile phone protective film has also increased greatly. Conventional mobile phone film is mainly aimed at the surface anti-scratch protection of the mobile phone display, and rarely involves the protection of the back or side of the mobile phone. Protection is basically protected by a thicker phone plastic or rubber case, which ruins the phone's original design aesthetic. Even if a conventional mobile phone film is used on the back of the mobile phone, it will easily fall off due to low viscosity, or when the back of the mobile phone has a curved surface, it cannot be attached. The ordinary decorative film is usually a paper base layer, which has poor shock resistance and requires It is not easy to tear off when removing, and it is ...

Even if a conventional mobile phone film is used on the back of the mobile phone, it will easily fall off due to low viscosity, or when the back of the mobile phone has a curved surface, it cannot be attached. The ordinary decorative film is usually a paper base layer, which has poor shock resistance and requires It is not easy to tear off when removing, and it is easy to have residual glue
