Organic modified monomer, preparation method thereof and application of organic modified monomer in water reducing agent
The invention relates to the technical field of water reducing agents, and discloses an organic modified monomer, a preparation method thereof and application of the organic modified monomer in a water reducing agent, and the preparation method of the organic modified monomer comprises the following steps: S1, taking amino acid and cyanuric chloride, mixing, and dropwise adding into a solvent; adding an acid-binding agent, heating to 30-50 DEG C, and reacting to obtain a base solution A; s2, additionally taking polyethylene glycol, dropwise adding the polyethylene glycol into the base solution A, heating to 60-100 DEG C, reacting, and removing the solvent to obtain a base solution B; and S3, adding maleic anhydride and a polymerization inhibitor into the base solution B, and reacting at 105-120 DEG C to obtain the organic modified monomer. The amino acid, the polyethylene glycol, the cyanuric chloride and the maleic anhydride are used as raw materials, a Y-shaped organic modified monomer can be prepared by utilizing the spatial effect of the cyanuric chloride, and then the organic modified monomer is introduced into the water reducing agent, so that the effects of reducing viscosity and improving dispersity can be effectively realized.
本发明涉及减水剂技术领域，公开了一种有机改性单体及其制备方法、其在减水剂中的应用，所述有机改性单体的制备方法，包括如下步骤：S1取氨基酸、三聚氯氰，混合，滴加至溶剂中；再加入缚酸剂，加热至30‑50℃，反应，得到基液A；S2另取聚乙二醇，滴加至基液A中，加热至60‑100℃，反应，脱除溶剂，得到基液B；S3另取马来酸酐、阻聚剂，加入至基液B中，于105‑120℃下反应，得到有机改性单体。本发明以氨基酸、聚乙二醇、三聚氯氰和马来酸酐为原材料，利用三聚氯氰的空间效应，可制备Y型的有机改性单体，再将有机改性单体引入至减水剂中，可有效实现降粘和提高分散性的效果。
