The invention relates to a preparation method of an inorganic porous ultra-light spherical particle material, which comprises the following steps: weighing preparation raw materials of core particles according to a mass ratio, mixing the preparation raw materials of the core particles, grinding, adding the ground material into a granulator, and granulating to obtain granules; weighing raw materials for preparing the coating layer according to the mass ratio, mixing the raw materials for preparing the coating layer, and grinding to prepare coating slurry; coating the granules with the coating slurry, and then drying the coated granules; and putting the dried coated granules into a calcining furnace for calcining, wherein the calcining temperature is between the melting temperature of the core granules and the melting temperature of the coating layer. According to the method, firstly, the core particles are melted and foamed to generate gas, the coating layer can seal pores of foaming balls of the core particles during calcination, meanwhile, micropores are generated in the surface of the coating layer in the calcination process, and finally the melted and wrapped porous ultra-light spherical microparticles with the micropores in the surface are obtained.
本发明涉及一种无机多孔超轻质球型微粒材料的制备方法，按质量比称取核心颗粒的制备原料，将核心颗粒的制备原料混合进行研磨，之后将研磨料添加到造粒机中造粒，得到粒料；按质量比称取包覆层的制备原料，将包覆层的制备原料混合进行研磨，制成包覆浆料；采用包覆浆料包覆粒料，然后将包覆好的粒料进行干燥；将干燥后的包覆粒料放入煅烧炉内进行煅烧，其中煅烧温度在核心颗粒的熔化温度和包覆层的熔化温度之间。本发明先使核心颗粒熔化发泡产生气体，包覆层在煅烧时会封闭核心颗粒发泡球的孔隙，同时在煅烧过程中包覆层表面又会产生微气孔，从而最终得到表面具有微气孔的熔融包裹的多孔超轻质球型微颗粒。
