Styrene-acrylic emulsion-toughened geopolymer and production method thereof

The invention relates to styrene-acrylic emulsion-toughened geopolymer. The styrene-acrylic emulsion-toughened geopolymer comprises the following raw materials in parts by weight: 100 parts of a salicraw material, 35-80 parts of an alkali-activator and 0.5-3 parts of a toughening agent; the alkali-activator is formed by mixing 0-20 parts of sodium hydroxide and 80-100 parts of a water glass solution with a molar ratio of 1.2-3.4; and the toughening agent is silane coupling agent-modified styrene-acrylic emulsion. A production method of the styrene-acrylic emulsion-toughened geopolymer is simple, meanwhile, the salic raw material is effectively recycled, the produced styrene-acrylic emulsion-toughened geopolymer is high in product additional value, high in compressive strength and good intenacity, and has excellent mechanical performance, especially a ratio of bending strength to compressive strength, the problems of large brittleness and a low ratio of bending strength to compressivestrength of geopolymer are
