With the development of nowadays building trade, cement is as a kind of construction material having extensively using value, its demand
Amount is being continuously increased, and the at the same time requirement to the kind and quality of cement is also being constantly increasing, and how to be ensured or carried
Under conditions of high strength of cement and physical properties, production and the application cost of cement are reduced, turns into a popular problem.
It is well known that some additives are filled in cement can improve in cement the addition content of mixing material and some other
Performance, in recent years people cement additive is updated, and develop different properties by substantial amounts of scientific experiment
Cement additive；The major defect of existing cement additive is：Function is single, and comprehensive effectiveness is poor, and cost is high, and effect is not
Substantially, engineer applied is not easy to, is yielded poorly, strength of cement is low.
The content of the invention
It is an object of the present invention to provide a kind of composite cement admixture and preparation method thereof.Outside the composite cement
Adding agent to process, simple, cost is low and service efficiency is high.
Technical scheme：A kind of composite cement admixture, by 10~14 parts of zinc chloride, methyl polyethylene glycol 4
~6 parts, 3~5 parts of iron chloride, 2~4 parts of ammonium sulfate, 10~14 parts of calcium hydroxide, 10~14 parts of aqueous isopropanol, retarder 1~
3 parts and 1~3 part of composition of defoamer.
Foregoing composite cement admixture, according to weight meter, by 12 parts of zinc chloride, 5 parts of methyl polyethylene glycol, iron chloride
2 parts of 4 parts, 3 parts of ammonium sulfate, 12 parts of calcium hydroxide, 12 parts of aqueous isopropanol, 2 parts of retarder and defoamer form.
Foregoing composite cement admixture and preparation method thereof, include following steps：
（1）Put into heat in reactor after the zinc chloride of formula ratio, the poly- second two of methyl, iron chloride are mixed with aqueous isopropanol and rise
Temperature reaction；
（2）By the ammonium sulfate of formula ratio and calcium hydroxide according to 1：It is slowly added to after 1 mixing in the reactor of step 1, A is made
Product；
（3）It is 1 by obtained A product additional proportion：1 retarder and defoamer, under 60~80 DEG C of constant temperatures stir 20~
30min, room temperature is cooled to, produced.
Beneficial effects of the present invention：Compared with prior art, the present invention has advantages below：
Simple production process of the present invention is convenient, and cost is cheap, and positive effect, is easy to engineer applied；Cement prepared by the present invention
Additive can improve cement output, strengthen strength of cement, small on the influence of cement compression strength early stage, can meet engine request；Energy
Improve cement mechanical property and pore structure, improve the antifreeze grinding aid performance of cement, reduce cement permeability, adjust cement setting
Time, increase concrete density, have the function that energy-conserving and environment-protective；The present invention cement additive compared with commercially available additive,
Improved with significant performance, market promotion prospect is wide.
