Abstract

The invention relates to an anti-static hardened plate and a preparation method thereof. A method for preparing an antistatic hardened sheet, comprising the steps of: providing a substrate, the substrate having two opposite surfaces; forming an uncured hardened coating precursor on at least one surface of the substrate; compounding an antistatic coating on the hardened coating precursor For the release film of the coating, during the compounding process, the antistatic coating and the hardened coating precursor are arranged opposite to each other to obtain a composite sheet; and the hardened coating precursor in the composite sheet is cured to obtain a hardened coating, and then the separation film is removed. forming a film to obtain an anti-static hardened sheet; the anti-static hardened sheet comprises a substrate, and at least one surface of the substrate is provided with a laminated hardened coating and an anti-static coating. Using the above-mentioned preparation method of the anti-static hardened sheet can improve the quality of the anti-static hardened sheet.

Description

technical field [0001] The invention relates to the technical field of sheets, in particular to an antistatic hardened sheet and a preparation method thereof. Background technique [0002] Resin boards (such as PVC, PMMA, PETG, PC, etc.) are widely used in the fields of transparent protection of precision equipment and transparent partitions of clean rooms due to their good processability and electrical insulation properties. But ordinary resin boards have higher surface resistivity (>10 14 Ω / cm 2 ), it is easy to accumulate static electricity during use, resulting in electrostatic dust collection, reducing the yield of electronic product manufacturing, and even causing adverse consequences such as fire and explosion. reduced to 10 6 ~10 8 Ω / cm 2 , to reduce static charge accumulation. At the same time, as a protective material, its surface should have a certain hardness and wear resistance, so that its surface can be cleaned regularly. [0003] The traditional ant...
