Static crushing agent and preparation method thereof

The invention discloses a static crushing agent and a preparation method thereof, and belongs to the technical field of static blasting. The static crushing agent is prepared from the following raw materials in parts by weight: 20 to 30 parts of precipitates, 50 to 60 parts of nano-calcium oxide and 1 to 3 parts of sodium lignosulphonate. The precipitates, the nano-calcium oxide and the sodium lignosulphonate are stirred and mixed; then, drying and packaging are performed to prepare the fast static crushing agent; the problems of low hydration reaction speed and lower crushing efficiency of the conventional static crushing agent are solved. The preparation steps are simple; the obtained static crushing agent has better flowability; the hydration reaction speed is high; during the construction, no hole jet phenomenon occurs; the crushing efficiency is high. 本发明公开了种静态破碎剂及其制备方法，属于静态爆破技术领域。本发明包括以下重量份数的原料：20～30份沉淀物、50～60份纳米氧化钙和1～3份木质素磺酸钠，是将沉淀物、纳米氧化钙和木质素磺酸钠搅拌混合后，干燥、包装制得快速静态破碎剂，有效解决了传统静态破碎剂水化反应速度慢，且破碎效率较低的问题。本发明制备步骤
