Electronic product rear cover with burnt-out texture and preparation method thereof

Abstract

The invention discloses an electronic product rear cover with burnt-out textures and a preparation method thereof, and relates to the technical field of electronic product rear covers, burnt-out cloth is adopted, the burnt-out cloth has rich colors and texture patterns, the specific colors and patterns can be set through lasers according to needs, pattern printing is not needed, and the production efficiency can be improved. According to the application, the glass fiber cloth is soaked in the modification treatment liquid containing the sulfydryl-terminated hyperbranched polymer for click reaction, so that the sulfhydrylated glass fiber cloth is prepared, and the strength of the glass fiber layer is improved. The connecting layer is the modified epoxy resin, and the modified epoxy resin improves the bonding strength between the connecting layer and the glass fiber layer and between the connecting layer and the scratch-resistant layer. And the impact resistance of the electronic product rear cover is improved, so that the stress dispersion is better realized.
