Steel fiber resin anchoring agent suitable for deep underground engineering surrounding rock support and preparation method thereof
The invention discloses a steel fiber resin anchoring agent suitable for deep underground engineering surrounding rock support and a preparation method of the steel fiber resin anchoring agent, and particularly relates to the technical field of steel fiber resin. The steel fiber resin anchoring agent comprises the following components in parts by mass: 100 parts of mixed resin mortar and 3-5 parts of a curing agent, the mixed resin mortar is prepared from unsaturated polyester resin, 0.8 to 1.1 parts of accelerant, 450 to 550 parts of stone powder and 0.5 to 1.5 parts of steel fiber; the curing agent is prepared from silicon powder, ethylene glycol, water, benzoyl peroxide (BPO) and 2, 4-dichlorobenzoyl peroxide (DC). The steel fiber resin anchoring agent has the beneficial effects that the prepared steel fiber resin anchoring agent is high in self-strength, particularly, the shearing strength of the cured resin anchoring agent is greatly improved due to the fact that steel fibers are contained in the steel fiber resin anchoring agent, the use amount of the resin anchoring agent is huge in the rapid supporting process of underground engineering, and the anchoring agent is good in self-thermal stability and not prone to cracking. And the anchoring strength of an anchoring body structure can be well improved, and the anchoring force of an anchoring body is increased.
本发明公开了一种适用于深部地下工程围岩支护的钢纤维树脂锚固剂及其制备方法，具体涉及钢纤维树脂技术领域。钢纤维树脂锚固剂的组成成分及质量配比包括：混合树脂胶泥100份和固化剂3～5份；混合树脂胶泥包括不饱和聚酯树脂、促进剂0.8‑1.1份、石粉450～550份和钢纤维0.5～1.5份；固化剂由硅粉、乙二醇、水、过氧化苯甲酰(BPO)、2.4‑二氯过氧化苯甲酰(DC)组成。有益效果：本发明制备的钢纤维树脂锚固剂，自身强度高，尤其是钢纤维在其中大大提高了树脂锚固剂固化后的抗剪强度，在地下工程快速支护工艺中树脂锚固剂使用量巨大，而这种锚固剂自身热稳定性好，并能较好的提高锚固体结构的锚固强度，增大锚固体自身锚固力。
