Abstract
A structural flame retardant high strength low exothermic polymer grouting material for consolidating, belonging to a technical field of polyurethane material, is produced by combined the polyether polyol and the modified isocyanate in a weight ratio of 100:(100-160), leading to internal reaction temperature ≤100° C., strength ≥60 mPa, bonding ≥3 mPa, oxygen index ≥28% while no halogen and no effect on water quality, odor level (80° C.) ≤3.5, and fog test ≤5 mg (which means no physical additive flame retardant is diffused into the environment). In particular, with no halogen, which is known as environmental hormones, in the plasticizers, there will be less combustion smoke, wherein the present invention will not release corrosive or irritating hydrogen halide gas, nor produce toxic carcinogens polybrominated benzoxins and polybrominated dibenzofurans, thereby avoiding the long-term impact of the material on the environment.
