Concrete glue reducing agent and preparation method thereof
The invention belongs to the technical field of concrete admixtures, and relates to a concrete glue reducing agent and a preparation method thereof, the concrete glue reducing agent comprises the following raw materials by weight: 0.5-3% of a composite microcapsule, 1-5% of mesoporous silica, 0.5-4% of a phase change composition, 0.2-2% of a polycarboxylic acid copolymer, 15-30% of fly ash, 0.1-1% of natural organic acid, 0.05-0.5% of a dispersant, and the balance of water. According to the invention, a composite microcapsule technology is adopted, the repairing agent epoxy resin and polyurethane are filled into microcapsules, when tiny cracks appear in a concrete structure, the cracks are effectively and automatically filled and blocked, the mesoporous silica has a pore structure and a large pore volume, and the microencapsulated paraffin is filled, so that gaps of the concrete microstructure can be filled, and the crack repairing effect is improved. And the microencapsulated paraffin absorbs or releases heat when the environment temperature changes, so that the internal temperature of the concrete is effectively adjusted.
本发明属于混凝土外加剂技术领域，涉及一种混凝土减胶剂及其制备方法，一种混凝土减胶剂，按以下重量份的原料组成：复合微胶囊0.5～3%、介孔二氧化硅1～5%、相变组合物0.5～4%、聚羧酸共聚物0.2～2%、粉煤灰15～30%、天然有机酸0.1～1%、分散剂0.05～0.5%、余量为水。本发明以复合微胶囊技术，将修复剂环氧树脂和聚氨酯填入微胶囊中，当混凝土结构出现微小裂缝时，有效自动填补和封堵裂缝，介孔二氧化硅具有的孔隙结构和较大的孔隙体积，填充了微胶囊化石蜡，可以填充混凝土微观结构的空隙，提高其密实性和强度，微胶囊化石蜡在环境温度变化时吸收或释放热量，有效帮助调节混凝土内部温度。
