Abstract

The invention relates to a preparation method of a coal-base heat generating agent, belonging to the crossing field of material science and new energies. The coal-base heat generating agent is prepared by mixing and granulating coal powder, an oxidizer and catalyst powder. The method solves the problem of quick safe cracking of rock, concrete, bridge piers, storied houses and the like, is simple in preparation technique and easy to operate, and is suitable for the existing industrial production equipment conditions. The method can implement industrial production, and is safe and reliable in the production process. The product is granular, has the advantages of high heating value, lower quantity of generated gas, high pressure attenuation speed, narrow work application range, low rock cracking sound, high speed, high efficiency and high cleanness in the use process, and is simple, safe and convenient to use and operate. The product has the characteristics of high quality, high antistatic property and safe and stable storage and transportation process. The production process does not discharge three wastes, is harmless to the human body and environment, and is clean, environment-friendly and pollution-free. The method has the characteristics of wide raw material sources and low economic cost.

Description

technical field [0001] The invention relates to a method for preparing a coal-based heating agent, which belongs to the cross field of material science and new energy. Background technique [0002] Stone cracking products are inseparable from mining, rock fracture, bridge demolition and other fields. The existing rock-cracking products are mainly divided into two types: industrial explosives and rock-cracking agents. As we all know, there are great safety hazards in the use of industrial explosives, and the controllability of the rock-cracking process is poor; most of the rock-cracking agents are static rock-cracking agents, and most of them have the disadvantages of extremely slow rock-cracking speed, low rock-cracking efficiency, and large environmental pollution. Studies have shown that when rocks are heated for a short period of time, thermal expansion and other external forces do work, and rocks can be easily and quickly broken. Exothermic agents with high calorific va...
