1. A structural flame retardant high strength low exothermic polymer grouting material for consolidating, consisting of: a modified isocyanate component and a polyol component which are polymerized together, wherein a mass ratio of the modified isocyanate component to the polyol component is (100-160):100; a structural formula of the modified isocyanate component is:, the polyol component comprises: polyether polyol which adopts 6-functionality sorbitol as an initiator, 4,4′-bis-sec-butylaminodiphenylmethane, silicone oil, and a reactive catalyst, wherein the polyether polyol which adopts the 6-functionality sorbitol as the initiator accounts for 50-70% of a total weight of the polyol component; 4,4′-bis-sec-butylaminodiphenylmethane accounts for 25-45% of the total weight of the polyol component; the silicone oil accounts for 1-3% of the total weight of the polyol component; and the reactive catalyst accounts for 2-4% of the total weight of the polyol component.
