| titleOfInvention | The method that silane coupler modified polyethers prepares collapse protective poly-carboxylic acid water reducing agent |
| abstract | The present invention relates to a kind of methods that silane coupler modified polyethers prepares collapse protective poly-carboxylic acid water reducing agent.The present invention uses silane coupling agent, polyether compound, unsaturated carboxylic acid class monomer etc. is main reaction raw materials, a kind of polycarboxylate water-reducer is prepared by first hydrolyzing again the method that Williamson's etherificate is condensed then combined polymerization again, that is halogenated silanes coupling agent first hydrolyzes, Williamson's etherification reaction occurs with polyether compound again, etherification product and alkenyl silanes coupling agent hydrolysate are condensed, condensation product again with unsaturated polyoxyethylene ether, molecular weight regulator, the polycarboxylate water-reducer of the silane coupler modified polyether lateral chain with a plurality of branch-like is made in unsaturated carboxylic acid class monomer under the action of initiator by free radical copolymerization.The present invention is simple and easy to control, the degree of polymerization is high, low in cost, energy-efficient, environment friendly and pollution-free, is successfully realized severely sterically inhibition effect, shows the guarantor more excellent than common polycarboxylate water-reducer and collapses characteristic. |
