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: 40-85 parts of hyperbranched polyether; 110 to 150 parts of modified alkylene alkenyl polyoxyethylene ether; 16 to 25 parts of acrylic acid; 10.0 to 15.0 parts of sodium methallyl sulfonate; 1-6 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 durability of the concrete is improved, the service life is prolonged, and environmental pollution such as carbon emission and construction waste caused by building demolition is reduced. 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：40~85份；改性烷撑烯基聚氧乙烯醚：110~150份；丙烯酸：16~25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。本发明提高混凝土耐久性，延长使用寿命，减少因建筑物拆除造成的碳排放、建筑垃圾等环境污染。通过降低水泥用量、减少用水量。
