Photochromic material, preparation method and application thereof, and mobile phone rear cover
The invention relates to a photochromic material, a preparation method and application thereof and a mobile phone rear cover. Forming a ceramic film layer on the surface of the supporting layer by adopting a ceramic material; the material of the supporting layer comprises at least one of ceramic, metal or glass; the ceramic material comprises photochromic ceramic and a fluxing agent; the photochromic ceramic comprises at least one of barium-magnesium-silicon-oxygen system ceramic, barium-zirconium-magnesium-tantalum-oxygen system ceramic, titanium dioxide system ceramic, sodium-bismuth-titanium-oxygen system ceramic, potassium-sodium niobate system ceramic or zirconate system ceramic; the first fluxing agent is magnesium oxide; the second fluxing agent comprises at least one of boric acid, yttrium oxide, zirconium oxide, sodium fluoride, lithium fluoride or ethyl silicate. The magnesium oxide serving as the first fluxing agent can be in synergistic interaction with the second fluxing agent and is compounded with the photochromic ceramic, so that the effect of reducing the melting temperature of the ceramic material is achieved, the spraying effect is effectively improved, and the comprehensive performance of a formed ceramic film layer is improved.
本申请涉及一种光致变色材料及其制备方法以及应用、手机后盖。采用陶瓷材料在支撑层的表面形成陶瓷膜层；支撑层的材料包括：陶瓷、金属或者玻璃中的至少一种；陶瓷材料包括光致变色陶瓷和助熔剂；光致变色陶瓷包括：钡镁硅氧体系陶瓷、钡锆镁钽氧体系陶瓷、二氧化钛体系陶瓷、钠铋钛氧体系陶瓷、铌酸钾钠体系陶瓷或者锆酸盐体系陶瓷中的至少一种；第一助熔剂为氧化镁；第二助熔剂包括：硼酸、氧化钇、氧化锆、氟化钠、氟化锂或者硅酸乙酯中的至少一种。氧化镁作为第一助熔剂可以与第二助熔剂协同增效，与上述光致变色陶瓷复配，实现降低陶瓷材料熔融温度的效果，有效地提高喷涂效果，提高形成的陶瓷膜层的综合性能。
