Synthesis of Polycarboxylate superplasticizer copolymerization reaction can be divided into the following three: ① direct polymerizable monomer copolymerizable: This method is generally first prepare a polymerization-active monomer (usually methoxy polyethylene glycol methacrylate), and then mixed with a certain proportion of the monomer solution polymerization directly from the system. ② aggregated functional method: This method is mainly the use of existing polymer modified using known molecular weight polycarboxylic acids, polycarboxylic acid liquor manufacturers Sichuan, in the catalyst and polyether at higher temperatures by esterification graft. ③ situ polymerization and grafting: The law is to compensate for the defect aggregation after functional method developed to polyether carboxylic acids unsaturated monomer polymerization reaction medium. Ester crosslinking type agents Chongzhi an acrylic ester synthetic macromolecules partially cross-called MPCs (with three polyoxyethylene chain link) Polycarboxylate superplasticizer. Of poly (ethylene oxide) chain length in the cement of liquidity, the role of Zeta potential and cement compatibility, etc., and that the MPC-7 is a good performance of polycarboxylate based superplasticizer. Grafted type agents grafted copolymer superplasticizer is the latest product of superplasticizer research and development, including the orientation reaction such superplasticizer polyether compound with a carboxylic acid polymer body, polyether-modified high acid polymer composites, etc., usually of a molecular weight of 1000-2000 and an end carboxylic acid polymer is an alkoxy group, and the other end is a hydroxyl group or an amino group in the polyoxyethylene non-aqueous solvent graft modified; or to polyene polyamine polymer modified to obtain a graft rate is high and stable products, polycarboxylate liquor manufacturers, their water reduction and slump retention performance are superior. Introducing an amino group in the molecular structure, Hainan polycarboxylic acid liquor manufacturers to improve the cement composition fluidity retention performance, and to promote the cement hydration; through an ester bond or an alkylene amide bond modified graft, effectively extending the storage period. Sichuan liquor manufacturers polycarboxylate, polycarboxylic acid liquor manufacturers, high-strength construction materials (view) Ltd provided by the Linyi City high-strength building materials. Linyi high-strength building materials Limited (www.lygqjc.cn) is specialized in "polycarboxylate superplasticizer, polycarboxylate liquor, poly carboxylic acid liquor," the business, the company adhering to the "honesty, hard service" concept, in order to You provide the most quality products and services.
