| titleOfInvention | A kind of preparation method of polyphosphate water reducer |
| abstract | The invention discloses a kind of preparation method of polyphosphate water reducer, it is characterised in that：Allow isoamyl alcohol polyoxyethylene ether and pyrophosphoric acid that phosphating reaction occurs and obtains isoamyl alcohol polyoxyethylene ether phosphate ester monomer first, radically homo then occurs in aqueous using ammonium persulfate as initiator, using mercaptopropionic acid as conditioning agent and obtains target product.The preparation method of the present invention is simple, raw materials used single and inexpensive, cost is low, and the polyphosphoric acid water reducer obtained is non-volatile, substantially nontoxic, biological degradability is good and has fine water-reducing rate and collapsing property of guarantor. |
