| titleOfInvention | A kind of sustained-release polycarboxylic super plasticizer and preparation method thereof |
| abstract | The invention discloses a kind of sustained-release polycarboxylic super plasticizer and preparation method thereof, which is that unsaturated carboxylic acid, unsaturated polyether and beta-unsaturated esters are carried out under the effect of oxidant, reducing agent and chain-transferring agent made from free radicals copolymerization reaction.Beta-unsaturated esters molecular weight of the present invention is smaller, and preparation process is simple, easily-controllable, and yield is high, three-waste free discharge.There are two kinds of ester bonds that the hydroxyl of carboxyl and phosphate group and polyalcohol is formed in the small-molecular-weight beta-unsaturated esters, form the ester bond of the different gradient hydrolysis abilities under alkaline environment, after sustained-release polycarboxylic super plasticizer is made as raw material by the use of it, the ester bond of this gradient hydrolysis ability has ensured the sustained release of concrete system sustained-release polycarboxylic super plasticizer, makes super plasticizer that there is superior diminishing and guarantor to collapse effect. |
