▎ 摘  要

NOVELTY - A concrete anti-cracking anti-seepage agent comprises 1-10 wt.% modified sulfonated graphene, 1-15 wt.% hydrophobic substance, 0.1-2 wt.% emulsifier A, 0.001-0.01 wt.% defoaming agent, and balance water. USE - Concrete anti-cracking anti-seepage agent. ADVANTAGE - The anti-seepage agent improves flexural tensile resistance of concrete, prevents permeation of water and chloride salts through pores into concrete, and greatly improves durability of concrete. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of concrete anti-cracking anti-seepage agent comprising mixing silane compound with amino, sulfonated graphene solution and emulsifier B, adding to first reaction kettle, heating to 40-60 degrees C, continuously stirring for 6-24 hours at speed of 300-2000 revolutions/minute to obtain modified sulfonated graphene emulsion, adding hydrophobic substance, emulsifier A, defoaming agent and water, adding to second kettle, and mixing and stirring at room temperature for 1-3 hours at speed of 2000-3000 rpm.
