Coated slow-release alkali activator and geopolymer
The invention belongs to the field of petroleum well cementation and cementing materials, and particularly relates to a coated slow-release alkali activator and a geopolymer, the coated slow-release alkali activator is composed of an excitation type inner core and a protection type shell, the inner core is sodium silicate, the shell is calcium silicate, and the coated slow-release alkali activator comprises the following raw materials in parts by weight: 7.5-30 parts of calcium chloride, 30 parts of sodium silicate, 5-10 parts of calcium silicate, 5-10 parts of calcium carbonate, 5-10 parts of calcium carbonate, and 5-10 parts of calcium carbonate. And 100 parts of water. The raw materials are wide in source and low in price, the dissolution rate of sodium silicate is controlled by wrapping the outer layer of sodium silicate with calcium silicate, then the coagulation time of the geopolymer is controlled, and the problem that the thickening time of the geopolymer activated by sodium silicate is difficult to regulate and control is solved.
本发明属于石油固井及胶凝材料领域，具体涉及一种包覆型缓释碱激活剂及地质聚合物，所述包覆型缓释碱激活剂由激发型内芯和保护型外壳组成，所述内芯为硅酸钠，所述外壳为硅酸钙，以重量份计，其原料组成为：氯化钙7.5‑30份，硅酸钠30份，水100份。本发明原料来源广泛，价格低廉，通过对硅酸钠外层包裹硅酸钙，实现硅酸钠溶解速度的控制，进而实现地质聚合物凝结时间的控制，解决硅酸钠激活地质聚合物稠化时间难调控的难题。
