Gray black polished thin rock plate prepared from double-peak grading glaze and glaze preparation method

The invention relates to a grey black polished thin rock plate made of double-peak grading glaze. The preparation method of the double-peak pole glaze matching material comprises the following steps: weighing fine powder glaze, frit particle coarse powder and a composite additive solution according to a ratio of 70: 30: 30, putting the fine powder glaze and the composite additive solution into a glaze cylinder, stirring at a constant speed of 150-200r/min by using a stirring pump until the mixture is completely uniform, slowly adding the frit particle powder, uniformly stirring at a stirring speed of 150-200r/min, and uniformly stirring at a stirring speed of 150-200r/min to obtain the double-peak pole glaze matching material. The specific gravity of the prepared bimodal graded glaze is 1.73 to 1.83, and the Engler viscosity of the prepared bimodal graded glaze is 38 to 45 S. 本发明涉及采用双峰级配釉料制作的灰黑色抛光薄型岩板。所述双峰极配釉料的制备方法，包括：按比例细粉釉:熔块颗粒粗粉:复合添加剂溶液＝70:30:30称取，将细粉釉与复合添加剂溶液放于釉缸中，采用搅拌泵匀速搅拌，搅拌速度150～200r/min，直至完全均匀，再慢慢加入熔块
