Anticorrosive interface treating mortar and preparation method thereof
The invention relates to an anticorrosive interface treating mortar which is prepared from the following raw materials in parts by weight: 10-15 parts of calcium bentonite, 20-25 parts of flake graphite powder, 10-15 parts of calcium/magnesium-base bentonite, 1-2 parts of formamide, 1-2 parts of urea, 0.5-0.8 part of sodium dodecyl benzene sulfonate, 2-3 parts of sodium alginate, 4-6 parts of fatty acid amine, 200-220 parts of sand, 160-180 parts of cement, 20-24 parts of titanium dioxide, 20-30 parts of bisphenol A epoxy resin emulsion, 2-3 parts of chitosan, a right amount of water, 20-25 parts of assistant and 13-16 parts of naphthalene high-efficiency water reducing agent. The mortar can seal the gaps in the substrate, reduce the absorptivity of the decrease and ensure the binding and gelation of the facing mortar under better conditions. The mortar has the advantages of high binding force and no aging or hydration, and can uniformly bind the walls with different water absorptivities. The assistant is utilized to enhance the compression resistance and folding strength of the mortar and improve the workability, anti-sagging property, thixotropy and antisettling property.
