Microcapsule modified ash geopolymer self-healing separating wall material and preparation process thereof
According to the microcapsule modified ash residue geopolymer self-healing isolation wall material and the preparation process thereof, the material is the microcapsule modified ash residue geopolymer self-healing isolation wall material; the microcapsule modified ash geopolymer self-healing isolation wall material is prepared by taking water-in-oil-in-water composite emulsion as a capsule core healing agent, wherein the water-in-oil-in-water composite emulsion is prepared from a sodium silicate solution by adopting a secondary emulsification process and takes water as a continuous phase; the microcapsule is taken as a reinforcing material and is added into an ash geopolymer to form the microcapsule modified ash geopolymer self-healing isolation wall material; the microcapsule is a polyurethane single-wall microcapsule prepared from polyurethane and a capsule core healing agent through one-time polymerization reaction by adopting an in-situ polymerization technology, or a polyurethane/melamine resin double-wall microcapsule prepared from polyurethane, melamine resin and a capsule core healing agent through two-time polymerization reaction by adopting an interfacial polymerization technology; the ash geopolymer is generated by taking fly ash and sand as basic raw materials and taking a sodium silicate solution as an alkali activator through a geopolymerization reaction.
本发明通过了一种微胶囊改性灰渣地聚物自愈合隔离墙材料及其制备工艺，该材料是一种微胶囊改性灰渣地聚物自愈合隔离墙材料，是以硅酸钠溶液采用二次乳化工艺制成的以水为连续相的水包油包水复合乳液作为囊芯愈合剂制成微胶囊，并将所述微胶囊作为增强材料加入灰渣地聚物中形成所述微胶囊改性灰渣地聚物自愈合隔离墙材料；所述微胶囊为采用原位聚合技术将聚氨酯与囊芯愈合剂通过一次聚合反应所制成的聚氨酯单壁微胶囊，或者是采用界面聚合技术将聚氨酯和密胺树脂与囊芯愈合剂通过两次聚合反应所制成的聚氨酯/密胺树脂双壁微胶囊；所述灰渣地聚物是以粉煤灰与砂作为基本原料，采用硅酸钠溶液作为碱激发剂，以发生地聚合反应生成的。
