Abstract

The invention discloses a hydrophobic group-containing anti-corrosion reinforced concrete water discharge pipe and a preparation method thereof. The anti-corrosion reinforced concrete water discharge pipe is characterized by using flyash, ore slag powder, metakaolin, gypsum, sodium sulfate, a naphthalene-based superplasticizer, sand, gravels, bisphenol-a epoxy resin E-44, benzo peroxide, acrylic acid, N,N-dimethylethanolamine, organic montmorillonite, cement, steel fiber, calcined diatomite, steel bars, tetrabutylammonium fluoride, cationic polyacrylamide and the like as raw materials. Water-borne epoxy resin is prepared by a graft copolymerization method; a network structure with mutually penetrating polymers and cement base materials is obtained; the organic montmorillonite is used as a filing material; a polymer solution intercalation method is used for adding the organic montmorillonite into a water-borne epoxy resin base body; a water-borne epoxy resin / montmorillonite nanometer composite material is prepared; uniform magnetic field is exerted on a steel fiber concrete mixture; steel fiber concrete in unidirectional distribution is prepared; the fiber utilization rate is high; the enhancement effect is good.

Description

technical field [0001] The invention relates to a preparation method of a reinforced concrete drainage pipe, in particular to a corrosion-resistant reinforced concrete drainage pipe containing a hydrophobic group and a preparation method thereof. Background technique [0002] With the development of urban construction, sewage treatment plants have begun to be built. A large amount of industrial wastewater and domestic sewage need to enter the sewage treatment plant through drainage pipes. Wastewater and sewage often contain acid or other corrosive substances with different concentrations, which requires drainage pipes. Has strong corrosion resistance. [0003] In Liu Yuanxiang's article "Research on the Properties of Alkali-Activated Slag Fly Ash Concrete and Its Application in Drainage Pipes", the raw materials were prepared from fly ash, slag, alkaline activator, FKJ special admixture, sand and gravel aggregate, etc. Alkali slag fly ash concrete was produced; when feeding...
