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, Jinan-acid liquor manufacturers, using known molecular weight polyethylene acid, in the role of 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. Make a unilateral concrete to reduce water consumption by 20% -30%. Compared with ordinary water reducer, polycarboxylate liquor manufacturers, superplasticizer even larger amount, Hefei polycarboxylate liquor manufacturers, the slump reached 20cm-30cm, Anhui polycarboxylate liquor manufacturers, it will not cause too much The bleeding and segregation phenomenon occurs and delay setting time. Polycarboxylate superplasticizer is a kind of molecular structure was comb, containing more carboxyl polymer surfactants at low dosage, without changing at the same time concrete workability of concrete can be significantly reduced water consumption, and significantly improve the strength of concrete; or significantly alter the workability of the concrete in a low water-cement ratio and slump when small loss. Its low dosage, high water reduction, high slump performance, low shrinkage of concrete, and cement better compatibility, adjustable and strong molecular structure of high performance potential and environmental advantages make it increasingly The more widespread concern civil sector researchers. Development of high performance concrete and specialty mortars makes polycarboxylate superplasticizer admixtures will become the future trend of development and applications. Recognized as the world's excellent performance superplasticizer, polycarboxylate superplasticizer exhibited a series of very good performance.
