Embodiment

[0022] Graphene coating process of the present invention comprises the following steps:

[0023] 1. Preparation of graphene ink

[0024] 1A. Take 50 parts of graphene, 30 parts of resin, and 20 parts of diluent and pour them into the medicine tank of the ink disperser; after fixing the medicine tank, turn on the mixer at a speed of 200r / min and stir for 5 minutes.

[0025] 1B. Increase the speed of the mixer to 500r / min, stir for 20 minutes, and fully mix the above substances.

[0026] 1C. Slowly increase the speed of the mixer to 1000r / min, and stir for 10 minutes.

[0027] 1D. Take out the evenly stirred ink, that is, the graphene ink, and place it in a ventilated, dry, and cool environment with a temperature of 18°C-23°C for later use.

[0028] 2. Coating and printing with graphene ink

[0029] 2A. Install the roll-shaped film material to be coated on the material shaft of the mobile phone protective film production equipment (circular knife machine), and select the side...

Abstract

The invention relates to the technical field of production of mobile phone protective films, in particular to a graphene coating process. The graphene coating process includes the following steps that1, graphene printing ink is prepared; and 2, the graphene printing ink is used for coating printing, wherein a corona treater is used for carrying out corona treatment on a protective film raw material, and the graphene printing ink is coat-printed on the surface of the protective film raw material through a rotary wheel type screen printer; and the graphene printing ink with which the protectivefilm raw material is coated is dried through a dryer, the graphene printing ink is completely attached to the surface of the protective film raw material, and finally a graphene coated product is obtained. The graphene coating process is not limited in traditional equipment any more, the coating efficiency is greatly improved, the coating effect is better, the product precision is high, graphenecan be greatly saved, and waste is avoided.

Description

technical field [0001] The invention relates to the technical field of mobile phone protective film production, in particular to a graphene coating process. Background technique [0002] Graphene is a two-dimensional crystal. The common graphite is formed by stacking planar carbon atoms arranged in a honeycomb order. The interlayer force of graphite is weak, and it is easy to peel off each other to form a thin film. graphite flakes. When the graphite sheet is peeled off into a single layer, this single layer with a thickness of only one carbon atom is graphene. The latest discovery of graphene is the most effective method for people to prevent corrosion. Using graphene as a protective film can significantly delay the corrosion rate of metals and make them stronger and more resistant to damage. Graphene is not only a new star in the electronics industry, but also has unlimited prospects in traditional industries. Its application directions include marine anti-corrosion, met...
