Ultrahigh-dispersion type water reducing agent and preparation method thereof
The invention relates to an ultra-high dispersion type water reducing agent and a preparation method thereof. Relates to the field of concrete admixtures. Comprising the following components in parts by weight: 50 to 70 parts of hyperbranched polyether A, 120 to 140 parts of modified alkylene alkenyl polyoxyethylene ether, 17.5 to 24.3 parts of acrylic acid, 10.0 to 15.0 parts of sodium methallyl sulfonate, 1 to 6 parts of an initiator, 0.7 to 4 parts of a chain transfer agent, 0.23 to 2 parts of a reducing agent and 180 to 300 parts of water. The modified alkylene alkenyl polyoxyethylene ether is one or more of ethylene glycol monovinyl polyethylene glycol ether and 4-hydroxybutyl vinyl polyethylene glycol ether. The initiator is one or more of ammonium persulfate, potassium persulfate or hydrogen peroxide. The chain transfer agent is one or more of isopropanol, sodium hypophosphite or sodium formate. The reducing agent is one or more of vitamin C, sodium hydrogen sulfite or ferrous sulfate. According to the invention, the performance of the PCE is fundamentally improved. And the water consumption is reduced by reducing the cement consumption.
一种超高分散型减水剂及其制备方法。涉及混凝土外加剂领域。包括以下重量份的组分:超支化聚醚A：50~70份，改性烷撑烯基聚氧乙烯醚：120~140份，丙烯酸：17.5~24.3份，甲基丙烯磺酸钠：10.0~15.0份，引发剂：1~6份，链转移剂：0.7~4份，还原剂：0.23~2份，水：180~300份。所述改性烷撑烯基聚氧乙烯醚为乙二醇单乙烯基聚乙二醇醚、4‑羟丁基乙烯基聚乙二醇醚中的一种或几种。所述引发剂为过硫酸铵、过硫酸钾或过氧化氢的一种或几种。所述链转移剂为异丙醇、次磷酸钠或甲酸钠的一种或几种。所述还原剂为维生素C、亚硫酸氢钠或硫酸亚铁中的一种或几种。本发明从根本上提升PCE的性能。通过降低水泥用量、减少用水量。
