Further, mother liquor further includes auxiliary material, and the auxiliary material is one or more, the auxiliary material weight in sucrose monoester and white sugar
It is 2~8 parts to measure part..
The purpose designed in this way is that polyalcohol end group is an aliphatic group, has independent hydrophobic grouping outside it, makes
It is conducive to the flowing of cement powder, with grinding aid preferable third with excellent mobile performance, and with preferable dispersibility
Glycol substitutes part alcamine compound, the performance of cement can be made more preferable, moreover it is possible to reduce cost.
Calcium lignosulfonate has good dispersibility, can improve mill efficiency, improves unit-hour output, reduces power consumption,
Each raw material component can also be promoted to play synergistic effect, improve the adaptability of cement grinding aid and cement.
Meanwhile its intensity 20%~40% can be improved in Magnetized water cement.Variation of the aqueous solution after by magnetization treatment is than pure
Water is big.Wherein hydrone is polar molecule, and in light water, hydrone attracts each other to form macromolecular mass, not by macromolecular
The unimolecule that group attracts is water-dispersed between big micel.Compared with macromolecular mass, the physical and chemical activity of unimolecule water is stronger,
But since unimolecule water is seldom in light water, thus the activity of water is not high, cannot make the abundant aquation of cement, aquation can only be in water
Mud particle surface carries out.After magnetic water, macromolecular mass rupture becomes single hydrone and again proper alignment, increases moisture
Electrical attraction power between son.Since the physical and chemical activity and penetration of unimolecule water are stronger, can penetrate into inside cement granules,
Make the abundant aquation of cement, to improve the intensity of concrete.
Moreover amino resins, film-forming resin, organosilicon moisture repellent and calcium lignosulfonate hardenite are combined, and are filled in
Between cement voids, make cement that there is more highly-acidproof and toughness.
Beneficial effects of the present invention are at least following one：
1. polyalcohol end group is an aliphatic group, there is independent hydrophobic grouping outside it, makes it have excellent mobility
Can, and with preferable dispersibility, be conducive to the flowing of cement powder, substitute part alcamines with the preferable propylene glycol of grinding aid
Compound can make the performance of cement more preferable, moreover it is possible to reduce cost.Calcium lignosulfonate has good dispersibility, Neng Gouti
High mill efficiency improves unit-hour output, reduces power consumption, moreover it is possible to promote each raw material component to play synergistic effect, improve cement
The adaptability of agent and cement.Acid flux material is merged for polyalcohol and lignin derivative, ethoxyl methyl cellulose ether and third
Olefin(e) acid hydroxyl ethyl ester has certain dispersibility, can improve the compression strength after blended cement, sucrose monoester in auxiliary material or
White sugar has the function of slow setting, the effect of reaching diminishing power saving by hydroxy compounds, hydroxycarboxylate and its derivative.
2. being capable of providing acidic environment in the preparation to merge for polyalcohol and lignin derivative, and it is capable of providing neutrality
Environment assists the chain tra nsfer of carboxyl, improves final products stability, after being mixed with special cement, is obviously improved compression strength.Ammonia
Base resin, film-forming resin, organosilicon moisture repellent and calcium lignosulfonate hardenite are combined, and are filled between cement voids, are made
Cement has more highly-acidproof and toughness.
3. replacing light water, Magnetized water cement that its intensity 20%~40% can be improved by magnetized water.Aqueous solution is by magnetic
Change treated variation it is bigger than pure water.Wherein hydrone is polar molecule, and in light water, hydrone attracts each other to be formed greatly
Micel, the unimolecule not attracted by macromolecular mass are water-dispersed between big micel.Compared with macromolecular mass, unimolecule water
Physical and chemical activity is stronger, but due in light water unimolecule water it is seldom, thus water activity it is not high, the abundant water of cement cannot be made
Change, aquation can only be carried out in cement particle surface.After magnetic water, macromolecular mass rupture becomes single hydrone and again whole
Neat arrangement, increases the electrical attraction power between hydrone.It, can since the physical and chemical activity and penetration of unimolecule water are stronger
It penetrates into inside cement granules, makes the abundant aquation of cement, to improve the intensity of concrete.
