Abstract

The invention discloses a high-temperature-resistant anti-aging resin anchoring agent, belonging to the technical field of roadway support materials. According to the invention, montmorillonite is crushed, then impregnated with hydrochloric acid and finally undergoes filtering and separation so as to obtain filter residues; the filter residues are mixed with moss pulp prepared from Polytrichum alpinum for culture, then the cultured filter residues undergo oscillation together with a sodium silicate solution, and the obtained mixture is subjected to filtering and separating so as to obtain a filter cake; the obtained filter cake and hydrochloric acid are subjected to oscillation, dipping and heating reaction, and then filtering and separating are carried out so as to obtain a pre-modified filter cake; the pre-modified filter cake is carbonized and then undergo mixing and grinding together with natural resin so as to obtain a modified self-made high-temperature-resistant anti-aging filling material; the filling material, bisphenol A type unsaturated polyester resin, dimethylaniline and tetrachlorobenzoquinone are uniformly mixed to obtain a component A; lauroyl peroxide, dibenzoyl peroxide and water are uniformly mixed to obtain a component B; and in use, the component A and the component B are mixed so as to obtain the high-temperature-resistant anti-aging resin anchoring agent. The high-temperature-resistant anti-aging resin anchoring agent has excellent ageing resistance, can maintain high compressive strength and anchoring force under a high temperature condition and exerts good supporting effect in a severe underground environment.

Description

technical field [0001] The invention discloses a high-temperature-resistant and anti-aging resin anchoring agent, which belongs to the technical field of roadway support materials. Background technique [0002] The method of firmly fixing metal bolts, deformed steel bars, and internal threaded pipes in concrete and rock foundation holes to replace embedded steel bars is called "anchor". Anchoring methods are generally divided into two types: the metal expansion bolt method and the chemical bonding method. Metal expansion bolts are fixed by mechanical force to expand the metal sheet and generate friction after squeezing the hole wall. They can only be used for anchoring non-structural parts under static loads, and their application range is narrow. The chemical bond anchoring is to use chemical adhesive to fix the metal rod. When the adhesive is cured, the matrix-adhesive layer-metal rod are firmly combined into a whole. Therefore, chemical anchoring is essentially an overa...
