High-density high-mechanical-strength anchoring agent for coal mine

Abstract

The invention discloses a high-density high-mechanical-strength anchoring agent for a coal mine. The anchoring agent is prepared from, by weight, 100 parts of main ingredients, 14-22 parts of curing agent, 25-45 parts of filler and 100-160 parts of distilled water; the main ingredients comprise, by weight, 100 parts of isophthalic unsaturated polyester, 10-20 parts of fumed silica, 3-7 parts of dimethyl-p-toluidine and 4-8 parts of dimethylaniline; the curing agent is prepared from, by weight, 100 parts of dibenzoyl peroxide, 5-10 parts of diethylene glycol and 6-10 parts of microcrystalline cellulose; the filler is prepared from, by weight, 20-35 parts of modified asphalt, 10-20 parts of calcined clay, 15-35 parts of calcium phosphate bone cement, 20-35 parts of clay, 20-40 parts of glass beads, 25-45 parts of sodium lignin sulfonate, 10-20 parts of talcum powder, 4-12 parts of sepiolite powder and 15-25 parts of wollastonite powder.

Description

technical field [0001] The invention relates to the technical field of anchoring agents, in particular to a high-density and high-mechanical-strength anchoring agent for coal mines. Background technique [0002] Anchoring agent is the most widely used bonding and anchoring material in modern times. It is composed of high-performance unsaturated polyester, curing agent and other chemical additives. The application of resin anchoring agent in coal mines in my country has a history of more than 50 years. With the country's high attention to coal mine safety and the continuous increase in the amount of anchoring agent, the scope of application continues to expand, and higher and higher requirements are put forward for the performance of anchoring agent. , There are many problems in using traditional general-purpose unsaturated resin as anchoring agent products: such as poor thermal stability, low density and mechanical strength. In view of the above problems, people in this field...
