Drain Pipe and Manufacturing Method Therefor
A drain pipe is manufactured from a cement mixture which comprises cement 20-30 weight percent, sand 30-40 weight percent, broken-stone chip 31-45 weight percent in 4-20 mm size, admixture 0.2-0.3 weight percent, and functional additives. The functional additives shall be added and mixed additionally. The functional additives include PUD (Waterborne Polyurethane Dispersion) 10-15 weight percent, PVA (Polyvinyl Alcohol) fiber 4-8 weight percent in 2-3 mm size, MEHEC (methylethylhydroxyethylcelluloe) 2-4 weight percent, calcium carbonate 4-6 weight percent, degenerated silicate 2-4 weight percent, epoxy group emulsion 1-2 weight percent, fluorosilicate magnesium 1-2 weight percent, cyclopentasiloxane 1-2 weight percent, triglycerides 6-10 weight percent, glycidyl neodecanoate 2-4 weight percent, sodium, acrylate copolymer 2-4 weight percent and dichlorodimethylsilane 3-6 weight percent, and water for remaining portion based on cement 100 weight percent.
