Concrete reinforcing agent and preparation method thereof
The invention discloses a concrete reinforcing agent and a preparation method thereof. The reinforcing agent comprises 600-820 parts of deionized water, 50-160 parts of unsaturated acid, 80-200 parts of unsaturated ester, 2-10 parts of acrylamide, 5-40 parts of a nonionic surfactant and a proper amount of titanium salt, organic titanium, organic chromium, manganese salt, organic manganese, magnesium salt, organic magnesium, an oxidation component, a reduction component, a chain transfer agent and the like. The unsaturated acid, ester, acrylamide and organic titanium used in preparation have high activity, are polymerized or crosslinked in oxidation reduction, wrap the nonionic surfactant to form a net structure, and capture solid particles, so that the solid particles are fully combined with a water reducing agent, and the dispersity of cement particles is expanded. The organometallic compound is grafted into the polymer in a grafting manner, so that the cement strength is improved, and the supplemented titanium salt, magnesium salt, manganese salt and the like can help to utilize tricalcium silicate. The sensitivity of the water reducing agent can be reduced, the mixing performance is improved, the dosage is reduced, and the later strength and durability are ensured.
一种混凝土增强剂及其制备方法，该增强剂包括：去离子水600‑820份、不饱和酸50‑160份、不饱和酯80‑200份、丙烯酰胺2‑10份、非离子表面活性剂5‑40份以及适量的钛盐、有机钛、有机铬、锰盐、有机锰、镁盐、有机镁、氧化组分、还原组分、链转移剂等。制备使用的不饱和酸、酯及丙烯酰胺、有机钛的活性高，在氧化还原中发生聚合或交联，将非离子表面活性剂包裹，形成网状结构，捕获固体颗粒，使其充分与减水剂结合，扩大水泥颗粒的分散性。有机金属化合物以嫁接的方式接入聚合物中，提高了水泥强度，补入的钛盐、镁盐、锰盐等能帮助利用硅酸三钙。本发明能够降低减水剂的敏感性，提升拌合性能，降低用量，保证后期强度和耐久性能。
