Problems solved by technology

Although adding surfactant can solve the problem of coating ills, adding too much will cause problems such as surfactant precipitation
More importantly, due to different construction techniques, not paying attention to the choice of diluent will cause the instability of the formula

Abstract

The invention provides a hard coating film to solve the problem of film cracking or curling. The technical proposal is that: the hard coating film comprises a support body and a hard coating; the hard coating has the compositions and weight portions as follows: 20 to 90 portions of UV curing acrylate, 2 to 20 portions of thermoplastic resin, 2 to 15 portions of photoinitiator, 0.2 to 15 portions of silicone, and 10 to 90 portions of solvent. The invention can inhibit cracking or curling caused by curing shrinkage, prohibit fingerprints or dusts, etc. from attaching on the surface of the film where attached fingerprints and dusts can be easily wiped off, and maintain the scratch resistance and wear resistance of the hard coating film.

Description

technical field [0001] The invention relates to a film material, in particular to a hard coating film. Background technique [0002] In recent years, the application of plastic products has become more and more extensive. Since the surface of most plastic products is easily scratched, in order to impart scratch resistance, it is necessary to stick a hard coat film or apply a protective paint layer before use. In addition, even for existing glass products, plastic films are increasingly attached to prevent scattering, but since the surface hardness of the film is insufficient, work to form a hard coat on the surface is widely carried out. [0003] The hard coat film is usually obtained by forming a thin coating film of about 2 to 10 μm on a transparent plastic film substrate using a thermosetting resin, an ultraviolet curable resin, or other composite materials. As a method of increasing the hardness of the hard coat layer, it is possible to increase the layer thickness of ...
