Anchoring agent with good thermal stability for coal mine

Abstract

The invention discloses an anchoring agent with good thermal stability for a coal mine. The anchoring agent comprises a main material, a curing agent, a filling agent and distilled water. The main material comprises the following components in parts by weight: 100 parts of terephthalic unsaturated polyesters, 1-5 parts of dimethyl-p-toluidine, 2-6 parts of dimethylaniline and 5-15 parts of fumed silica. The curing agent comprises the following components in parts by weight: 100 parts of peroxycyclohexanone, 2-6 parts of carboxymethylcellulose and 2-7 parts of diethylene glycol. The filling agent comprises the following components in parts by weight: 15-30 parts of modified asphalt, 10-30 parts of calcium phosphate bone cement, 5-15 parts of hydroxyapatite, 15-30 parts of calcined clay, 2-10 parts of organobentonite, 5-15 parts of halloysite, 10-20 parts of kieselguhr, 20-40 parts of mica powder, and 15-35 parts of talcum powder. The weight part ratio of the main material, the filling agent and the distilled water is 100: 10-18: 20-40:50-150.

Description

technical field [0001] The invention relates to the technical field of anchoring agents, in particular to an anchoring agent for coal mines with good thermal stability. 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 have carried...
