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), poly acid liquor, 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, Cangshan polycarboxylate liquor, a 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. Synthetic polymer material variety, Yinan polycarboxylates liquor, typically monomers are: acrylic acid, methacrylic acid, maleic acid, (meth) acrylate, ethyl (meth) acrylate, vinyl acetate, allyl sulfonate; freedom of the molecular structure of large, diversified approach polymerization synthesis process is relatively simple, additive manufacturing technology parameters can be controlled much of the potential of high-performance; polylactic acid-based reduction of water use agents, can replace more slag or fly ash cement, thereby enabling to reduce costs, and provide a technical guarantee for the industrial waste in concrete engineering large-scale use, in favor of green concrete, high performance development; synthesis process do not use formaldehyde, do not pollute the environment, conducive to the sustainable development of building materials.
