Thermal expansion stone cracking agent
The invention relates to a thermal expansion stone cracking agent, and belongs to the material science and new energy crossing field. The granular thermal expansion stone cracking agent is obtained through the following steps: weighing solid powders with the particle size of 1-100[mu]m according to a formula, uniformly mixing to obtain a powder mixture, adding starch gum into the powder mixture, uniformly stirring, kneading until dough with moderate hardness is obtained, and granulating. The prepared stone cracking agent is granular in shape, is convenient for filling in boring, can meet filing density requirements of cracked stones without tamping by using pneumatic picks, impact drills or special tools, and has the advantages of small stone cracking sound, fast speed, high efficiency, avoiding of water resource wastes and land surface pollution due to no use of water as a reaction raw material, clean use process, and simple, safe and convenient use operation; obtained products have good quality, and are safe and stable to store; the production process of the stone cracking agent has no emission of three wastes, is harmless to human body and environment, and is clean and environmentally-friendly; and the use process of the stone cracking agent is free from water, and is environmentally-friendly, and required raw materials have wide sources, so the economic cost is low.
