10~20 parts of benzoic anhydride polyester polyol.
To solve above-mentioned second technical problem, the technical scheme is that
A kind of above-mentioned polyether polyhydroxy tertiary amine cement grinding aid preparation method, it is characterised in that: the following steps are included:
A, aminated compounds and low hydroxyl value polyester polyol addition water are mixed, is stirred evenly;
B, chain extender, crosslinking agent and catalyst is added, stirs evenly;
C, 80~120 DEG C are heated to and is maintained, is chemically reacted 1~3 hour, polyether polyhydroxy tertiary amine cement grinding aid liquid is generated Body.
Preferably, the aminated compounds is polyether polyhydroxy tertiary amine or is polyether polyhydroxy tertiary amine and diethanol Dan Yi The mixture of Propanolamine.
Preferably, the low hydroxyl value polyester polyol is benzoic anhydride polyester polyol.
Preferably, the chain extender is ethylenediamine or N- dihydroxy aniline, and the crosslinking agent is N- methylene bisacrylamide acyl Amine or divinylbenzene.
Preferably, the catalyst is iron oxide Fe2O3.
By adopting the above-described technical solution, the beneficial effects of the present invention are:
Polyether polyhydroxy tertiary amine cement grinding aid of the invention is a kind of novel cement grinding aid, be chain extender, crosslinking agent, Under the action of catalyst, using diethanol monoisopropanolamine as main chain, using low hydroxyl value polyester polyol as branch, by artificially dividing Son design forms the macromolecule new material with " pectination " or " dendroid " molecular structure, contains ehter bond in molecular structure, Active function groups are the synthetic of amido.It has the advantage that
1, there is stronger absorption dispersibility and electrostatic screening effect, therefore more powerful to the grinding-aid effect of cement, to water The grinding-aid effect of mud is better than substances such as alcohol, hydramine, lipids.
2, have diethanol monoisopropanolamine to strength of cement value added later strength high-performance.In the base of identical addition content On plinth, intensity value added reaches 4-10Mpa within 28 days, is higher than diethanol monoisopropanolamine.
3, because of the substances such as polyether polyhydroxy tertiary amine and triethanolamine, diethanol monoisopropanolamine and other alcohol, hydramine, lipid There is good compatibility, when making cement grinding aid, diethanol monoisopropanolamine can be replaced to be used alone completely, it can also be with The matching of other substances uses.
4, due to the special construction of strand, there is good compatibility with each Series Admixtures of concrete, can also make It is directly used for concrete admixture.
