Seepage-proof cement
The invention discloses seepage-proof cement and belongs to the technical field of building materials. The seepage-proof cement comprises the following components in parts by weight: 15-25 parts of aluminophosphate cement soil, 7-8 parts of aluminium silicate, 0.5-1.3 parts of a melamine resin, 0.2-1.4 parts of N-N-dimethyl pyrrolidone, 0.2-1.5 parts of sodium dodecyl sulfate, 1-5 parts of asbestos powder, 0.3-1.5 parts of a quaternary ammonium bis-imidazoline corrosion inhibitor, 0.5-1.8 parts of a sulfonated-pheno-formoldehyde resin, 10-15 parts of calcium aluminate. 5-10 parts of glass fibers and 0.8-1.7 parts of urea. In the hydration process of the cement, hydrogen bonds are formed between the molecules of organic matters and the molecules of inorganic matters to reduce pores, and meanwhile, hydrophobic substances in the material can effectively produce a lotus effect, so that the seepage-proof cement has excellent seepage-proof property.
