Embodiment 1

[0022] Step 1) Add unsaturated polyester resin: 15kg; activated magnesium oxide: 0.6kg; initiator: 0.1kg; tert-butyl peroxybenzoate: 0.3kg; saturated resin: 8kg; zinc stearate: 1kg; carbonic acid Calcium: 6kg made into resin paste;

[0023] Step 2) Coat the resin paste evenly on the high-density polyethylene film, take the alkali-free glass fiber, and drop it between the upper and lower two layers of the high-density polyethylene film coated with the resin paste. The conveyor belt is sent to the pressing roller to fully impregnate the resin paste with the alkali-free glass fiber to form a sheet, which is then collected into a roll or folded cloth shape;

[0024] Step 3) Preparation of SMC: The material obtained in step (2) is thickened at 45°C for 7 hours to obtain an SMC composite material.

[0025] The tensile strength test results of the prepared material are shown in Table 1.

Embodiment 2

[0027] Step 1) Add unsaturated polyester resin: 20kg; activated magnesium oxide: 0.8kg; initiator: 0.3kg; tert-butyl peroxybenzoate: 0.4kg; saturated resin: 9kg; zinc stearate: 1.5kg; Calcium carbonate: 8kg made into resin paste;

[0028] Step 2) Spread the resin paste evenly on the PET film, take the alkali-free glass fiber, and drop it between the two layers of the upper and lower layers of the high-density PET film coated with the resin paste, and send it to the press through a conveyor belt. At the roller, the resin paste is fully impregnated with the alkali-free glass fiber to form a sheet, which is then collected into a roll or folded cloth;

[0029] Step 3) Preparation of SMC: The material obtained in step (2) is thickened at 45°C for 7 hours to obtain an SMC composite material.

[0030] The tensile strength test results of the prepared material are shown in Table 1.

Embodiment 3

[0032] Step 1) Add unsaturated polyester resin: 25kg; activated magnesium oxide: 1kg; initiator: 0.5kg; tert-butyl peroxybenzoate: 0.5kg; saturated resin: 10kg; zinc stearate: 2kg; calcium carbonate : 10kg made into resin paste;

[0033] Step 2) Coat the resin paste evenly on the high-density PET film, take the alkali-free glass fiber, and drop it between the two layers of the upper and lower layers of the high-density PET film coated with the resin paste, and send it through a conveyor belt Go to the pressure roller to fully impregnate the resin paste with the alkali-free glass fiber to form a sheet, which is then collected into a roll or folded cloth shape;

[0034] Step 3) Preparation of SMC: The material obtained in step (2) is thickened at 45°C for 7 hours to obtain an SMC composite material.

[0035] The tensile strength test results of the prepared material are shown in Table 1.

Abstract

The invention discloses a mobile phone film. The mobile phone film is composed of a PET material base film and an SMC composite material coating, the SMC composite material coating is coated on the surface of the base film, and the SMC composite material coating includes, by weight, 15-25 parts of unsaturated polyester resin, 0.6-1 part of a thickening agent, 0.1-0.5 parts of an initiator, 0.3-0.5 parts of a crosslinking agent, 8-10 parts of a low shrinkage additive, 1-2 parts of an internal release agent and 6-10 parts of a filler. The above SMC composite material is prepared through the steps of resin paste preparation, pretreatment and SMC composite material preparation. The generation of static electricity can be effectively prevented by adopting the above technical scheme; and the mobile phone film having a high transparency has no influences on the tough screen induction of the screen of a mobile phone as a mobile phone protection film.

Description

Technical field [0001] The invention relates to the field of diaphragms, in particular to a mobile phone film. Background technique [0002] With the continuous development of electronic product technology, smart phone technology has become more prominent. With the constantly updated smart phones, mobile phone protective films have also emerged and the demand is huge. At present, the conventional mobile phone film does not have the anti-static function, and it is easy to absorb dust during the application process, or it is difficult to accurately locate on the mobile phone screen due to electrostatic adsorption, which causes the use of the mobile phone to decrease after the film is applied. Therefore, the mobile phone film urgently needs to solve the technical problems caused by static electricity. Summary of the invention [0003] The purpose of the present invention is to overcome the problems existing in the prior art and provide a mobile phone film. [0004] In order to achiev...
