Carboxylate salt graft copolymerization water reducer is the brand-new high-performance water reducing agent of a class, and it has following characteristics: the water-reducing rate height: generally all more than 30%.Slump-loss is little: the slump was not lost substantially in 1-2 hour.The later strength height: gain in strength was more than 20% in 28 days.Volume is less: generally below 0.3%.
This class water reducer is the product that carries out the water reducer Molecular Structure Design according to concrete performance.Generally its structure is on long high polymer main chain, connects various active groups; (SO3), (COOH), oh group (OH) and polyoxy alkyl alkene class group [(CH for hydroxy-acid group as sulfonic acid group 2CH 2O) M-R].They must appear on the high polymer main chain with suitable ratio.
The raw material of synthetic macromolecule main chain has: vinylformic acid, methacrylic acid, the acid of horse fork-like farm tool used in ancient China, Ethyl acrylate, vinylformic acid hydroxyl second fat, vinyl acetate resin, sodium allyl sulfonate etc.
Graft copolymerization carries out in two steps, the at first synthetic polymer monomer that certain side chain lengths is arranged.And with these monomers with contain graft copolymerizations such as carboxylic acid, sulfonic acid to connect active group.Second step is for further to aggregate into binary or multiple copolymer with two or more multipolymer under the initiator effect.High molecular polymer water reducer of final formation.The length of main chain, active group kind, quantity have determined product performance.
Antifreezing agent described in the present invention is that calcium oxide, sodium-chlor list antifreezing agent or Sodium Nitrite add the compound antifreezing agent of sodium-chlor.
Described impervious agent is a kind of in calcium chloride, diatomite, flyash, resin emulsion or the water soluble resin; Described resin emulsion is vinyl acetate between to for plastic, vinylchlorid, acrylate; Described water soluble resin is a polyvinyl alcohol.
Described toxilic acid is a maleic acid; Described Vltra tears, promptly HPMC is a known substance, can buy from Foochow four directions chemical industry company limited or the good chemical science and technology of Shanghai fond dream company; Described amidosulfonic acid salt is the modification of wooden calcium sulfonate, is known substance, can be buied by Laiwu, Shandong water reducer factory.
Civil material solidifying agent of the present invention can change project organization, reduces construction costs, increase economic efficiency; Through the solidifying agent curing soil, can obtain the excellent comprehensive technical indicator, reach the requirement of " CJ/T3073-1998 " and " CJ/T80-98 " national sector standard,, just can replace the traditional material structural sheet of 40～60 cm thicks only with the solidified earth structural sheet of 15～20 cm thicks.Thereby saved comprehensive costs such as material, artificial, machinery, transportation, construction costs quite descends 30～42%.
Civil material solidifying agent of the present invention changes Soil structure, improves the physical and mechanical property of soil, thoroughly change soil and meet the water softening characteristic, make it become hydrophobic material, improve the intensity of solidified earth, comprise early strength and later strength, increase the density of soil, reduce to shrink, creep, improve hardening property, stability, improve the impermeability of solidified earth, freeze-thaw resistance, the weather resistance of increase solidified earth.
