一种抗冲击抗开裂瓷砖，由以下重量份的原料制成：伊利石20-30、蔷薇辉石15-25、锆硅渣18-26、造纸白泥12-19、固废磷化渣21-28、绿松石17-24、山砂19-27、水泥渣22-34、高钙白灰14-22、石墨烯8-17、焦宝石15-25、纳米氮化钛6-14、奥米纤维5-10。
一种抗冲击抗开裂瓷砖的制备方法，包括以下步骤：
(1)将蔷薇辉石、绿松石、水泥渣混合，粉碎，过70-90目筛，加入适量的水搅拌制成50-55％的浆液，在3000-4000r/min的转速下研磨20-30min，然后将球磨后的浆料以0.2-0.4Mpa的压力送入喷雾干燥造粒机中喷雾造粒，离心转盘转速为5000-6000r/min，喷雾干燥造粒机的进口温度为210-260℃，出口温度105-145℃，最后将所得的颗粒过80-100目筛，再在930-970℃温度下焙烧1-2h，冷却至室温，得物料A；
(2)取伊利石、蔷薇辉石、锆硅渣混合均匀，加热熔化成熔融液，然后采用压力为1.5-2.5MPa、气流速度为10-15m/s的高压高速空气将熔融液喷吹成絮状纤维，得物料B；
(3)将固废磷化渣、山砂、焦宝石混合均匀，粉碎，过100-120目筛，然后加入造纸白泥、高钙白灰、石墨烯、纳米氮化钛、奥米纤维等原料，在3000-5000r/min的转速下球磨20-40min，得物料C；
(4)将上述制得的物料A、物料B、物料C混合，在1000-2000r/min的转速下搅拌10-15min，然后加入相当于混合料重量5-7％的固含量为45％的水玻璃，在1500-2500r/min的转速下搅拌5-10min，静置16-22h后送入到成型机在60-70MPa的压力下压制成型，然后将压制好的砖坯在70-80℃的温度下干燥至含水量低于3％；
(5)将烘干后的砖坯置于马弗炉内进行煅烧：先以10-15℃/min的速率升温至1210-1260℃，保温2-3h，再以4-7℃/min的速率降温至760-820℃，保温1-2h，再以2-4℃/min的速率降温至560-590℃，保温0.5-1h；再置于微波煅烧炉内进行煅烧：先控制微波功率在800-900W，煅烧35-45min，再控制微波功率在600-700W，煅烧40-50min，再控制微波功率在300-400W，煅烧50-60min，随炉冷却至室温，即得成品。
