Ultralow-density high-strength ceramsite proppant and preparation method thereof
The invention provides an ultralow-density high-strength ceramsite proppant and a preparation method thereof.The ultralow-density high-strength ceramsite proppant takes a raw material containing bauxite as an inner core, the inner core is coated with a metal oxide layer, and the metal oxide layer is protected with a resin layer; wherein the metal oxide layer is made of MgO, Al2O3 or MgAl2O4 (magnesium oxide). The raw materials of the proppant are coated with a two-layer structure to form a core-shell structure, high-hardness MgO, Al2O3 or MgAl2O4 is used as a first coating layer, ultralow-density resin is used as a second coating layer, the first coating layer utilizes the characteristics of high hardness and corrosion resistance of oxide, and the second coating layer utilizes the characteristic of density of organic matter, so that ultralow density and high strength are both considered, and the proppant is suitable for being used as a core-shell structure. And the purpose of balancing ultra-low density and high strength is achieved.
本发明提供一种超低密度高强度陶粒支撑剂及其制备方法，以含有铝矾土的原料为内核，在内核外包覆有金属氧化物层，在金属氧化物层外保护有树脂层；其中，所述金属氧化物层为MgO、Al2O3或MgAl2O4。本发明在支撑剂的原料外包覆两层结构，形成核壳结构，将高硬度的MgO、Al2O3或MgAl2O4作为第一包覆层，将超低密度的树脂作为第二包覆层，第一包覆层利用氧化物高硬度、耐腐蚀的特点，第二包覆层利用有机物密度的特点，实现兼顾超低密度和高强度，达到平衡超低密度和高强度的目的。
