Abstract
The invention discloses a method for producing cane sugar modified polyglycol ether. The method comprises the following steps: adding 100 parts of polyglycol ether into a pressurizing and heating reactor, subsequently adding 10 parts of powder cane sugar, uniformly stirring, rising the temperature to be 11 DEG C, covering and pressurizing to be 10MPa, reacting and treating for 1 hour, subsequently introducing cooling water into a water jacket of the reactor so as to reduce the temperature of the reactant to be the room temperature, and pouring out so as to obtain the cane sugar modified polyglycol ether. The addition amount of the modified polyglycol ether in a cement grinding aid is 10-15% in percentage by mass. The cane sugar modified polyglycol ether is used as a raw material of the cement grinding aid. The cane sugar modified polyglycol ether has the advantages of lubrication, lubrication, cement activity improvement, cement strength improvement and cement grinding property improvement, and is applicable to application as the raw material of the cement grinding aid.
Description
Technical field
What the present invention proposed is grinding aid for cement grinding, specifically a kind of production method of sucrose modified poly (ethylene glycol) ether.
Background technology
Polyethers, also known as polyglycol ether, is the maximum a kind of synthetic oil of current sales volume.It is with oxyethane, propylene oxide, butylene oxide ring and tetrahydrofuran (THF) etc. for raw material, the simple linear polymer that open loop homopolymerization or copolymerization obtain under catalyst action.
Multiple unit take ether as a base polymer of constitutional features group.Be the important source material of producing urethane, there is the several functions such as froth breaking, breakdown of emulsion, dispersion, infiltration, emulsification.
Characteristic:
1 viscosity characteristics;
2 sticky pressure characteristics;
3 low-temperature fluiditys;
4 oilnesies;
5 thermo-oxidative stabilities;
6 water-soluble and oil solubles.
Polyglycol ether (abbreviation polyethers) is obtained through polyaddition reaction in the presence of a catalyst by initiator (compound containing active hydrogen group) and oxyethane (EO), propylene oxide (PO), butylene oxide ring (BO) etc.Polyethers output the maximum is for being used as initiator and epoxide (be generally PO and EO also) with glycerine (glycerol), by changing the condition such as feed way (mixing adds or separately adds), dosage ratio, reinforced order of PO and EO, produce various general polyether glycol.Polyethers (polyglycol ether) is the important derivatives of propylene oxide.
1, the YC series polyether of rigid foam is transparent viscous liquid, and character is comparatively stable, and slightly nontoxic, the non-corrosiveness of special odor, water-soluble, good in amine, fluoro trichloromethane and most organism intermiscibility.Polyethers is non-flammable explosives.
2, the YC series polyether of elastomerics, coating, tackiness agent is colourless or faint yellow viscosity transparent liquid, and character is comparatively stable, and slightly special odor is nontoxic, non-corrosiveness, good with most organism intermiscibility, is non-flammable explosives.
According to related data inquiry, at present, polyglycol ether not application in cement grinding aid.
Summary of the invention
In order to polyglycol ether being used as the raw material of cement grinding aid, the present invention proposes a kind of production method of sucrose modified poly (ethylene glycol) ether.The method, by reactor, adds polyglycol ether and sucrose, prepares the complex body of polyglycol ether and sucrose, realize can applying in cement grinding aid, improve the character of cement grinding aid.Solve the technical problem that modified poly (ethylene glycol) ether is used as to apply in cement grinding aid.
The scheme that technical solution problem of the present invention adopts is:
In mass ratio, 100 parts of polyglycol ethers are loaded in pressurization, reactor heating, then add the sucrose 10 parts of powdery, stir, be warming up to 110 DEG C subsequently, lid lid is pressurized to 10 MPas, reaction treatment 1 hour, then passes into water coolant in the water jacket of reactor, makes reactant cool to room temperature, pour out, become sucrose modified poly (ethylene glycol) ether.
The addition of modified poly (ethylene glycol) ether in cement grinding aid is 3-5% by mass percentage.
Positively effect, the present invention passes through with sucrose modified poly (ethylene glycol) ether, as the raw material of cement grinding aid.There is lubrication, slow setting, the increase activity of cement, improve cement products intensity, improve the advantage of cement grog grinding performance.Be suitable for applying as the grinding aid of cement grinding.
Embodiment
In mass ratio, 100 parts of polyglycol ethers are loaded in pressurization, reactor heating, then add the sucrose 10 parts of powdery, stir, be warming up to 110 DEG C subsequently, lid lid is pressurized to 10 MPas, reaction treatment 1 hour, then passes into water coolant in the water jacket of reactor, is that reactant cools to room temperature, pour out, become sucrose modified poly (ethylene glycol) ether.
Described polyglycol ether is also known as polyethers.
The addition of sucrose modified poly (ethylene glycol) ether in cement grinding aid is 3-5% by mass percentage.
In cement grinding aid, utilize polyglycol ether viscosity characteristics, sticky pressure characteristic, low-temperature fluidity, oilness, thermo-oxidative stability and water-soluble and oil-soluble characteristic, utilize the delayed coagulation of sucrose, therefore, it is possible in cement grog grinding process, frictional force between cement granules is reduced, contributes to flowing, and sucrose can prevent cement and moisture from producing rapid hardening, slow down the loss of the activity of cement, regulate cement products time of coagulation, the hydration reaction being beneficial to cement is complete.
Effect test,
Conventional cement grinding aids has the mixture of metallic salt and trolamine, tri-isopropanolamine, adds in the process of cement grog grinding, plays lubrication and levigate effect.Usually add by 10% of cement quality.After adding cement grinding aid, the frictional force of cement granules can be increased, be conducive to the levigate of cement, and not change the character of cement.
Adopt sucrose modified poly (ethylene glycol) ether of the present invention, the addition of metallic salt and trolamine and tri-isopropanolamine can be reduced, and be conducive to the levigate of cement clinker, and play low-temperature fluidity and oilness.Through the conventional cement grinding aids of equivalent and the simultaneous test of modification grinding aid of the present invention, can reduce the grinding time 20% of cement, and the finished cement presetting period shifts to an earlier date 1 hour, three days intensity improves 5%, 28 days ultimate compression strength and improves 10%.
Illustrate, adopt modified poly (ethylene glycol) ether of the present invention to have significant effect as the raw material of cement grinding aid.
