Reactive grouting reinforcement material with low smoke toxicity and high mechanical strength and preparation method thereof

The invention relates to a reactive grouting reinforcement material with low smoke toxicity and high mechanical strength and a preparation method of the reactive grouting reinforcement material, and belongs to the field of mining polymer grouting reinforcement materials. The reactive grouting reinforcement material is prepared from a component A and a component B according to a ratio of 1: 1, wherein the volume ratio of the components is 1. The coating comprises the following components: a silicate aqueous solution, a reaction stabilizer, a reaction promoter, polyisocyanate, a coalescing agentand a reinforcing agent, the obtained reactive grouting reinforcement material has the characteristics of low smoke toxicity and high mechanical strength, the smoke toxicity grade of the material canreach the quasi-safety grade, the compressive strength can reach 60 Mpa, the flame retardant property can realize self-extinguishing 1s away from fire, the safety performance is high, and the stability is good; meanwhile, the
