Polyethylene glycol, maleic acid (anhydride) monoesters superplasticizer polymaleic acid (anhydride) superplasticizer is maleic acid or maleic anhydride unit with polyethylene or polyethylene / propylene block After the first esterified copolymer polymerization methods. Hirata of maleic acid capped glycol ether and methyl-3-isobutene superplasticizer containing polyoxyalkylene side chains to overcome the gelling problem. Sun Santo et maleic anhydride with polyethylene glycol to esterification macromonomer of polyethylene glycol carboxylic acid ester, followed by addition of 2-acrylamido-2-methyl propene sulfonate and methacrylic acid, an aqueous solution of synthesis by copolymerizing the superplasticizer, Hainan ready-mixed mortar admixtures, study co-monomer ratio, measured reaction temperature, reaction time, and to decide the reaction rate constants obtained polymerization process kinetic equation . Jiannan to maleic anhydride, emulsifier OP as raw materials, triethylamine as a catalyst for the esterification reaction, the product of maleic anhydride monoesters, maleic anhydride homemade single-methacrylate monomer polymerization, the pre- mix mortar admixtures, with high activity and low activity initiator initiator complex combination of aqueous products caused by water reducing agent system obtained by the polymerization reaction of various concentrations. He Jing and other new synthetic route through polymer reaction method, with the S03 sulfonated styrene / maleic anhydride copolymer to introduce a sulfonic acid group, a sulfonic acid group through self-catalysis, Guangdong mixed mortar admixtures, in synthesized by esterification graft polycarboxylate type superplasticizer with polyoxyethylene side chains on the maleic anhydride groups. At present, most additives companies in order to save costs, generally using complex technology, the basis for the introduction of the mother of seven, a large number of complex early strength agent, retarder, although this can achieve early strength, retarding effect, Hunan ready-mixed mortar admixture , but a large number of complex other additives may cause poor compatibility with cement, late strength is not high even retraction, high costs, environmental pollution and other issues, and this is restricting our superplasticizer widely and the underlying causes of development. Therefore, research and development should be the molecular design superplasticizer, the concrete performance, environmental protection and other aspects into account, that is towards the high-performance, multi-functional, eco-oriented development. From molecular design to proceed, in-depth study of the relationship between the system of superplasticizer molecular structure and properties, and other aspects of the mechanism, by modification methods, development, production diversification and different properties of the series Polycarboxylate water reducing maternal and multifunction superplasticizer derivatives, real polycarboxylate superplasticizer widely used in our country. This will have a profound impact on China's development of materials technology, construction engineering and technological progress. Hainan mixed mortar admixtures, ready-mixed mortar admixtures, high-strength construction materials (view) provided by the high-strength Materials Co., Ltd. Linyi City. Linyi high-strength building materials Limited (www.lygqjc.cn) is a professional, "polycarboxylate superplasticizer, polycarboxylate liquor, liquor polycarboxylate" company. Since its inception, we adhere to the "good faith, sound management" approach, the courage of healthy competition in the market, so that the "poly-carboxylic acid liquor, polycarboxylate water reducer, pumping agent polycarboxylate" brand has a good reputation .
