摘要（英）：

The invention discloses a fluorine-contained organic silicone polymer-modified furfural-acetone-epoxy grouting material and a preparation method thereof. The fluorine-contained organic silicone polymer-modified furfural-acetone-epoxy grouting material comprises a fluorine-contained organic silicone polymer-modified furfural-acetone-epoxy grouting component (A) and a curing agent component (B) in a mass ratio of 100 to (12-35), wherein the fluorine-contained organic silicone polymer-modified furfural-acetone-epoxy grouting component (A) comprises the following raw materials in parts by mass: 100 parts of bisphenol-A epoxy resin, 10-30 parts of a fluorine-contained organic silicone polymer, 0-20 parts of dioctyl phthalate, 45-75 parts of furfural, 30-50 parts of acetone, 3-5 parts of an inorganic strong alkali aqueous solution; the curing agent component (B) is polyamine. The fluorine-contained organic silicone polymer-modified furfural-acetone-epoxy grouting material is good in compatibility between systems, free of phase separation, strong in mechanical properties, good in low-temperature toughness and excellent in thermocycling resistance.
