Problems solved by technology

[0002] PET film has excellent mechanical properties, heat resistance and high transmittance, but its surface hardness is low, wear resistance and impact resistance are poor. In order to improve the above defects, UV-curable coating ( UV curing coating), which has the advantages of energy saving, fast curing speed, no pollution, etc., is widely used in many fields such as printing industry, furniture floor, metal, plastic products, paper, electronic products, etc., but the resistance value of the surface of this film is relatively low High, the surface of the material is easy to accumulate charges, which brings a series of electrostatic hazards

Embodiment 1

[0010] Embodiment 1, the present invention includes the following raw materials in parts by weight, 54 parts of epoxy acrylate, 16 parts of trimethylolpropane triacrylate, 17 parts of dipropylene glycol diacrylate, 4 parts of benzoin dimethyl ether, diphenyl 4 parts of ketone, 5 parts of methacryloyl isopropyl phosphate, 2 parts of BYK-333, 3 parts of Darocur 1173.

[0011] Phosphate methacryloyl isopropyl ester is as the antistatic agent in the present invention, and the action mechanism of antistatic agent is hygroscopic mechanism and wetting mechanism, mainly absorbs the moisture in the air by surfactant characteristic, and surfactant produces polarization, A very thin conductive layer is formed on the surface to form a static leakage channel. At the same time, the antistatic agent lubricates the surface of the coating film, reduces the friction coefficient, and inhibits the generation of static charge to a certain extent. Therefore, the antistatic agent migrates to the coat...

Embodiment 2

[0015] Embodiment 2, the present invention includes the following raw materials in parts by weight, 55 parts of epoxy acrylate, 14 parts of trimethylolpropane triacrylate, 18 parts of dipropylene glycol diacrylate, 2 parts of benzoin dimethyl ether, diphenyl 5 parts of ketone, 4 parts of phosphomethacryl isopropyl ester, 3 parts of leveling agent, 2 parts of photoinitiator.

Embodiment 3

[0016] Embodiment 3, the present invention includes the following raw materials in parts by weight, 50 parts of epoxy acrylate, 18 parts of trimethylolpropane triacrylate, 14 parts of dipropylene glycol diacrylate, 5 parts of benzoin dimethyl ether, diphenyl 2 parts of methyl ketone, 6 parts of phosphomethacryl isopropyl ester, 1 part of leveling agent, 4 parts of photoinitiator.

[0017] In the present invention, in order to ensure the antistatic effect of the hard coating and reduce the production cost at the same time, it is the optimal solution when the weight fraction of the hard coating is 5, so Example 1 is the optimal solution.
