USE - As mobile phone backplane. ADVANTAGE - The mobile phone backplane has excellent colorful effect, wear resistance, hardness, thermal conductivity, heat dissipation and aesthetics, and use experience. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for manufacturing a mobile phone backplane involves (a) mixing diethylene glycol methyl ethyl ether, tetraethylene glycol dimethyl ether, isophorone, butyrolactone, and surfactant into the metal complex dye solution, stirring at 450-600 rpm for 15-20 minutes, and heating up 40-50 degrees C and stirring until completely dissolved, maturing for 1.5-2 hours, preparing the Aurora Bright Inkjet Ink for mobile phone backplane and spare, (b) ultrasonically dispersing zirconium dioxide, silicon dioxide, superfine magnesia, superfine alumina, glass fiber and graphene for 15-20 minutes until uniform, to obtain composition A, (c) adding polybutylene terephthalate, sodium metaphosphate, sodium sulfate, maleic anhydride, copper dialkyldithiocarbamate and dialkyldithio carbamate to the composition A obtained in step (b), stirring for 3-5 minutes at 45-55 degrees C, ultrasonically dispersing for 30 minutes, molding, and hot-pressing to make a plate-shaped blank, (d) heating the plate-shaped blank obtained in step (c) to 160-170 degrees C, keeping warm for 20-30 minutes, sintering at a temperature of 1000-1200 degrees C for 2-3 hours, and naturally cooling to room temperature to obtain a mobile phone backplane after post-processing, and (e) filtering and filling the mobile phone backplane prepared in step (d) with the aurora bright inkjet ink prepared in step (a) using a multi-stage filtering method to prepare a mobile phone backplane with a colorful effect.
