Refractory material precipitation agent and preparation method thereof
The invention provides a refractory material water reducing agent and a preparation method thereof, and the refractory material water reducing agent is prepared by mixing alkenyl alcohol, ethylene sulfide, ethylene oxide, maleic acid-acrylic acid copolymer and other components according to a certain proportion, carrying out esterification reaction, and then carrying out sulfonation reaction. The refractory material precipitation agent is prepared by selecting a novel sulfur-containing polyether macromonomer to carry out post-grafting reaction and then carrying out addition sulfonation reaction on a branched chain end double bond, the water consumption can be reduced by 50% or above, when the prepared refractory material precipitation agent is applied to a high-aluminum system refractory castable, the normal-temperature compression strength reaches 95 MPa, the anti-burst temperature reaches 900 DEG C, and the refractory material precipitation agent can be used for preparing refractory castable. The thermal shock resistance is more than 35 times.
本发明提供了一种耐火材料降水剂及其制备方法，由烯基醇、环硫乙烷、环氧乙烷和马来酸‑丙烯酸共聚物等组分按一定比例混合后，先通过酯化反应，再经过磺化反应制备而成。本发明通过选用新型含硫聚醚大单体进行后接枝反应并再对支链端双键进行加成磺化反应来制备耐火材料降水剂，其降低用水量可达50%以上，制备的耐火材料降水剂应用在高铝体系耐火浇注料时，其常温耐压强度达到95MPa，抗爆裂温度达到900℃，抗热震性35次以上。
