preparation example Construction

[0021] The present invention also provides a kind of preparation method of antistatic film, and this method comprises the following steps:

[0022] A. Preparation of coating solution: Based on 100 parts by mass of pressure-sensitive resin, 5-50 parts by mass of organic solvent, and 1-30 parts by mass of nanowires, first disperse the nanowires in the organic solvent, and then add Stir evenly into the pressure-sensitive resin to obtain a coating liquid. In the present invention, the combined use of pressure-sensitive resin and nanowires cannot be generalized, and can be formulated according to the electrical properties of nanowires. If the mass fraction of nanowires exceeds 30, the light transmission performance of the coating will be reduced; If the mass fraction of the nanowires is less than 1, it is difficult to form a network structure, and the antistatic effect is not good. Preferably, relative to 100 parts by mass of the pressure-sensitive resin and 5-50 parts by mass of ...

Abstract

The invention provides an anti-static film, which comprises a substrate and a coating formed on the substrate, wherein micropores are formed on the surface of the substrate; the coating is made of a resin pressure-sensitive adhesive which contains a reticular structure formed by nano-wires. The invention also provides a preparation method of the anti-static film. According to the anti-static filmand the preparation method thereof, when the anti-static film is used, the anti-static film can be attached to the surface of a liquid crystal display screen by virtue of the resin pressure-sensitiveadhesive in the anti-static film, and static electricity can be directly discharged to the air by virtue of the reticular structure of the nano-wires formed in the resin pressure-sensitive adhesive and the phenomenon that the nano-wires discharge electricity at the tips in the micropores of the substrate. The anti-static film has an excellent discharge effect and is convenient in operation.

Description

technical field [0001] The invention belongs to the field of film materials, in particular to an antistatic film and a preparation method thereof. Background technique [0002] When the insulating film material is rubbed, it is easy to generate static electricity, and when the liquid crystal display is working, it is also easy to generate static electricity. Static electricity is extremely harmful to equipment, workshops and human bodies. On the one hand, the film material is easy to absorb dust due to static electricity. For example, the outer surface of a liquid crystal display is easy to be stained with dust due to static electricity, making the screen blurred and affecting vision. On the other hand, static electricity is also easy to cause fire, especially in a purified coating workshop. After the substrate is coated, no matter it is cured by heat or ultraviolet curing, the surface will have strong static electricity when it is wound. The ion fan blows; moreover, due to...
