Description
Technical Field
The invention relates to a high polymer film material, in particular to a film material for protecting a curved screen of a mobile phone.
Technical Field
The mobile phone film is also called as mobile phone beauty film and mobile phone protective film, which is a film material for mounting mobile phone body and screen. The mobile phone film can protect eyesight and does not hurt eyes. In addition, according to the usage of different mobile phone films, the mobile phone films can be divided into: smart phone screen protection film, phone body protection film, da qin 150 film, peep-proof film, mirror film, AR film, frosted film, scratch-proof protection film, phone body decoration protection film, etc. According to the mobile phone film material, the mobile phone film can be divided into: PC protective film, PVC protective film, PET protective film, AR protective film, etc. of the mobile phone. In addition, the mobile phone films are classified into other categories according to different purposes and mounting modes.
With the popularization of digital products such as mobile phones in China, the protective film has become a general name of the screen protective film slowly, and the function of the protective film in the field of screen protective film materials is also five-door, so that the VIPO functional protective film is popular at the earliest time for high-definition scratch resistance. The materials have undergone years of development from the earliest PP materials to the current popular AR materials, and are slowly accepted by the vast cell phone population. In the current market, the film pasting products are various, the quality is more disordered, and many defective products fill the market, such as gum protective films, which are advocated by merchants once due to low cost, but the gum can damage mobile phone screens and the characteristics of difficult taking down and glue retention are not enough, so that the electrostatic pasting protective films made of PET or ARM are more available.
The current mobile phone film does not have the function of protecting a mobile phone, is not firm enough in installation and has poor structural stability. The traditional mobile phone screen protective film material is prepared from aromatic TPU and a coating. The mobile phone protective film material has the defects of poor yellowing, poor repairability and complex process. The existing mobile phone protective film has poor yellowing and no rebound resilience, and the preparation process is more complex and has low efficiency. Firstly, a TPU base film is prepared by tape casting, and then a coating is applied for construction, so that the process is long, the working procedures are multiple, and the cost is high. Cast TPU has no rebound resilience, no hand feel, no stain resistance, and poor yellow change.

(1) Coating the protective film paint for the curved screen of the mobile phone on a release film by using a micrometer wire rod until the thickness of a wet film is 150-200 micrometers, and forming a paint film;
(2) Placing the paint film which is subjected to blade coating in an oven for baking;
(3) And (4) after baking the paint film, coating a film with a fluorine film for later use.
The film material for protecting the curved screen of the mobile phone, which is prepared by the invention, can reach the thickness (100-150 mu m) of the traditional base material and has softness, and meanwhile, the film material has high stain resistance and high smooth hand feeling which are not possessed by TPU and TPH base materials. In addition, the invention has ideal attachable performance on any cambered surface, and can protect the display screens of mobile phones and pads from being broken in the process of falling on the ground while resisting general scratches. The product can be used in the fields of display screens of electronic products such as mobile phones and the like, and the single coating process replaces the processes of base films and coatings, so that the production cost is greatly reduced, and the production efficiency is improved.
