Description
Technical field
The invention belongs to cement composite grinding additive technical field, more particularly, to a kind of high-efficiency cement adding industrial wastes is again
Close grinding aid and preparation method thereof.
Background technology
Cement grinding aid is a kind of chemical addition agent improving cement grinding effect and performance, can significantly improve cement platform
When yield, each age strength of cement, improve its mobility.Cement grinding aid can be greatly lowered the electrostatic being formed in grinding process
Absorption bag ball phenomenon is it is possible to reduce the coalescence trend again of the ultra-fine grain being formed in grinding process.Cement grinding aid also can
Significantly improving cement fluidity, improving the grinding effect of grinding machine and the grinding efficiency of powder concentrator, thus reducing grinding energy.Use
The cement that grinding aid produces has relatively low compacting coalescence trend, thus being conducive to the handling of cement, and can reduce cement bunker
Wall cling phenomenon.As a kind of chemical addition agent, grinding aid can improve concrete scroll and excite aquation power, thus improving water
Mud early strength and later strength.
At present, the most main raw material(s) of liquid cement grinding additive market sold is triethanolamine, triethylene glycol, diethyl
The chemical substances such as glycol, ethylene glycol, glycerol, sodium chloride and water are composited, but the worsening shortages due to world petroleum resource,
The price of the main raw material(s) triethanolamine of grinding aid constantly rises, and therefore triethanolamine class grinding aid is expensive, generally pushes away
Wide application is restricted.The high-efficiency concrete grinding aid product seeking a kind of relatively low cost is that domestic and international grinding aid industry is badly in need of solution
Problem certainly, such as Chinese invention patent application 201310501664.1 be given " a kind of slag liquid composite grinding aids and
Its preparation method ", wherein relate to mixed alcohol and a large amount of use of molasses substitutes triethanolamine Main Function, improve strength of cement
Effect with improving cement effect, can increase the adaptability of cement and admixture, and can reach good effect.
Content of the invention
Decline to solve yield when above-mentioned cement grinding aid produces cement, reinforced effects reduce, and lead to cement production enterprise
The technical problem that production cost improves, the present invention provides a kind of output increased when producing cement, and reinforced effects are obvious, cement production enterprise
The high efficiency cement composite grinding additive and preparation method thereof that reduces of production cost.
A kind of high efficiency cement composite grinding additive of interpolation industrial wastes that the present invention provides, including triethanolamine, diethanol

90%.
In a kind of a kind of preferred embodiment of high efficiency cement composite grinding additive of interpolation industrial wastes that the present invention provides, institute
State coal-ethylene glycol waste liquid and predominantly include ethylene glycol, diethylene glycol, glycerol, 1,2 butanediols, 1,4 butanediols, propylene glycol
Mixture.
In a kind of a kind of preferred embodiment of high efficiency cement composite grinding additive of interpolation industrial wastes that the present invention provides, institute
State the mixture that industrial by-product molasses predominantly include sucrose, reducing sugar.
A kind of preparation method of the high efficiency cement composite grinding additive of interpolation industrial wastes that the present invention provides, walks including following
Rapid:
Step one, sodium thiosulfate are mixed with industrial by-product sodium chloride: mass percent is 0%-15% thiosulfuric acid
Sodium is added at room temperature in 20-90% water with 0%-13% industrial by-product sodium chloride and is thoroughly mixed until all molten
Solution；
Step 2, triethanolamine is added to mix with diethanol monoisopropanolamine: mass percent is 5%-25% tri- second
Hydramine is gradually added in above-mentioned mixed liquor and is uniformly mixed with 0%-20% diethanol monoisopropanolamine；
Step 3, addition industrial by-product molasses mixing: add the stirring mixing of 0%-10% industrial by-product molasses；
Step 4, addition coal-ethylene glycol waste liquid mixing: addition mass percent is 5%-40% coal-ethylene glycol waste liquid,
And be sufficiently stirred for more than 30 minutes finished product.
High efficiency cement composite grinding additive of a kind of interpolation industrial wastes of the present invention and preparation method thereof has beneficial as follows
Effect:
Low toxicity, non-volatile, steady sources, ample supply and prompt delivery, processing prepare simple, product raw material can be greatly lowered
This, grinding-aid effect increases substantially, and utilizes industrial wastes and side-product, and each age pressure resistance of the obvious water lift mud of energy in a large number
Degree, cement production enterprise can reduce the clinker usage amount of high energy consumption, how using the industrial wastes such as flyash and slag, production technology
Simply, product can be with long term storage.And this waste liquid is cheap, there is huge economic benefit.Generally it is suitable for, raw material becomes
This is low, reaches the effect of cost efficiency, does not reduce the grinding aid quality of product simultaneously, and also can improve product during the platform of certain cement
Amount, improves strength of cement, increases the adaptability of cement and additive.
Because industrial wastes being used as raw material in a large number, easy output precipitation and cement grinding aid in preparation process is led to produce
The unstable phenomenon of the colourity of product, must improve to its production technology, using the compounding coal-ethylene glycol waste liquid of substep and industry
The mode of byproduct sodium chloride solution, can effectively avoid producing precipitation.
In the case of same product quality, compound use triethanolamine and coal-ethylene glycol waste liquid be used alone three second
Hydramine is compared, and can save triethanolamine more than 20%.Utilize industrial wastes in a large number, in product, coal-ethylene glycol waste liquid consumption exists
Between 5% to 30%, consumption is big, can consume waste liquid in a large number, reduces the disposal of pollutants of environment.Add water the water of cement after cement grinding aids
Between 3 days comprcssive strength raising values of earth rubber sand 1.0-2.0mpa higher than domestic like product, user can save grog 2%- more
4%, cement production enterprise client can reduce 2-8 yuan/ton of production cost.Compare adaptability with blank cement good, normal consistency is used
The index such as the water yield and flow of cement mortar ratio is with low uncertainty, makes the more stable more high-quality of cement.
