Anti-cracking agent suitable for superfine copper tailing solidified bricks
The invention discloses an anti-cracking agent suitable for superfine copper tailing solidified bricks, the anti-cracking agent comprises modified rubber particles, hyperbranched polyester and silicate minerals, a preparation method of the modified rubber particles comprises the following steps: soaking the rubber particles in a sodium hypochlorite solution, taking out the soaked rubber particles, and washing the rubber particles with water until the rubber particles are neutral; naturally airing to obtain pretreated rubber particles, uniformly mixing a silane coupling agent containing double bonds with ethanol, adding the pretreated rubber particles, soaking, adding alkyl sulfonate containing double bonds and an initiator, stirring to react, and drying at room temperature after the reaction is finished. Through cooperation of the modified rubber particles, the hyperbranched polyester and the silicate minerals, the anti-cracking performance of the cured brick can be improved, the stability of the structure can be kept, and the strength of the cured brick is improved.
本发明公开了一种适用于超细铜尾矿固化砖的抗开裂剂，所述抗开裂剂包括改性橡胶颗粒、超支化聚酯和硅酸盐矿物，所述改性橡胶颗粒的制备方法包括以下步骤：将橡胶颗粒置于次氯酸钠溶液中浸泡取出用水清洗至中性，自然晾干得预处理的橡胶颗粒，将含双键的硅烷偶联剂与乙醇混合均匀，加入预处理的橡胶颗粒，浸泡后加入含双键的烷基磺酸盐和引发剂，搅拌反应，反应结束后在室温下干燥。本发明通过改性橡胶颗粒、超支化聚酯以及硅酸盐矿物一起配合，不仅能够提高固化砖的抗开裂性能，还能保持结构的稳定，提高固化砖的强度。
