Abstract

A silicate-modified polymer grouting material for leakage plugging is provided, which belongs to the technical field of silicate modification, includes 60% by weight of silicate-modified aqueous solution component, and about 40% of structural flame-retardant isocyanate. According to the proportion of the main total amount, the main components are classified into inorganic components, so the silicate-modified polymer grouting material for leakage plugging has excellent flame retardant performance, oxygen index ≥35%, adhesion ≥1.5 mPa, maximum reaction temperature ≤95° C., odor level (80° C.) ≤3.5, fog test ≤5 mg (without physical additive flame retardants diffusion to the environment). In particular, a main component of the silicate-modified aqueous solution, endows it with good surface resistance.
