Abstract

The invention discloses high-temperature-resistant and high-toughness resin for an anchoring agent and a preparation method of same. The resin comprises maleic anhydride, dicyclopentadiene, phthalic anhydride, propylene glycol and the like. The polymerization inhibitor can be used to prevent the progress of polymerization, in which polymerization inhibitor molecules react with chain radicals to form non-free radicals or incapable low-activity radicals, thereby terminating polymerization. The linear polyester is subjected to crosslinking curing with a vinyl monomer under the effect of an initiator and an accelerant to form resin with a net-shaped structure. The inorganic filler is added into the raw materials for preparing the resin, so that an organic-inorganic doping process is achieved,and the strength and toughness of the resin can be effectively improved. Meanwhile, components such as aluminum triphosphate and aluminum metaphosphate are generated through reaction of phosphoric acid and aluminum hydroxide, the components have good high-temperature resistance, and the high-temperature resistance of the resin can be effectively improved. The preparation method is low in raw material component cost, economical and practical, and has good practicability.

Description

technical field [0001] The invention relates to the technical field of resin preparation for anchoring agents, in particular to a high-temperature-resistant and high-toughness resin for anchoring agents and a preparation method thereof. Background technique [0002] Anchor, the method of firmly fixing metal bolts, deformed steel bars, and internal threaded pipes in concrete and rock foundation holes instead of embedded steel bars is called "anchor". Anchoring methods are generally divided into metal expansion bolt method and chemical bonding method. Among them, chemical bonding and anchoring are used to firmly combine the metal rod and the matrix into a whole with an adhesive. The adhesive used is called a resin anchor. The resin anchor is generally composed of special resins, high-strength fillers, curing agents, Accelerator and various additives. [0003] The resins used for anchoring agents in the market today generally have poor high temperature resistance and poor tou...
