| description | The invention discloses a preparation method and application of an anionic copolymer, the anionic copolymer is included, R1 and R3 are respectively hydrogen, alkali metal or CH3; a is an integer from 1 to 3000; b is an integer from 1 to 5000; c is an integer from 1 to 8000; m is an integer from 1 to 100; r2 is hydrogen, an element of the alkaline metal group, CH3 or. (CH2CH2O) mR1; r4 is hydrogen or CH3; and R5 is an alkyl group of C1-4. According to the present invention, with the arrangement of the anionic copolymer, when the anionic copolymer is adopted as the cement dispersant, the fluidity of the cement slurry or the concrete can be improved, and the slump retention time of the formed flowable concrete can be increased;
本发明公开了阴离子型共聚合物制备方法及其应用，包括阴离子型共聚合物，其中，R1、R3与分别是氢、碱金属或CH3；a是1到3000之整数；b是1到5000之整数；c是1到8000之整数；m是1到100之整数；R2是氢、硷金族元素、CH3或·(CH2CH2O)mR1；R4是氢或CH3；R5是C1-4之烷基。本发明利用阴离子型共聚合物的设置，在将阴离子型共聚合物作为水泥分散剂时，能增进水泥浆或混凝土的流动性，同时也能使所形成的流动性混凝土的坍度可维持时间增加。 |
