Description
Technical field
The invention belongs to building materials technology field, it is related to a kind of cement grinding aid and preparation method thereof, more particularly to one kind
The cement grinding aid and preparation method thereof of high reunion performance.
Background technique
In the grinding process of clinker, a small amount of additional substance (substance of liquid or solid) is added, it can be significant
It improves mill efficiency or reduces energy consumption, and do not damage this chemical addition agent additional substance common name of cement performance are as follows: cement
Grinding aid.Cement grinding aid is a kind of chemical addition agent for improving cement grinding effect and performance, can significantly improve cement platform
When yield, each age strength of cement, improve its mobility.The electrostatic formed in grinding process can be greatly lowered in cement grinding aid
Bag ball phenomenon is adsorbed, and the coalescence trend again of the ultra-fine grain formed in grinding process can be reduced.Cement grinding aid also can
Cement fluidity is significantly improved, the grinding effect of grinding machine and the grinding efficiency of powder concentrator are improved, to reduce grinding energy.It uses
The cement of grinding aid production has lower compacting coalescence trend, to be conducive to the handling of cement, and can reduce cement bunker
Wall built-up phenomenon.As a kind of chemical addition agent, grinding aid can improve concrete scroll and excite aquation power, to improve water
Mud early strength and later strength.Current cement grinding aid is complex chemical compound grinding aid mostly, usually organic matter surface
Active material, but its production cost is higher, the reunion performance of cement is poor, needs to improve cement grinding aid, therefore make
Standby modified cement grinding aid a kind of out is particularly important for cement preparation.
Summary of the invention
The present invention is directed to existing cement grinding aid high production cost, and the lubricity of cement grinding aid is low, and agglomeration difference etc. is no
Foot, proposes a kind of cement grinding aid and preparation method thereof of high reunion performance, production cost is lower, and simple production process is mixed
It measures that low, reinforcing effect is good, cement can be improved and obtain reunion performance and yield, be suitble to large-scale production.
A kind of technical solution of the present invention: cement grinding aid of high reunion performance, it is characterised in that: by following weight percent
The raw material of ratio is made: diesel oil 5-10%, Nacl 1-3%, methanol 1-3%, nekal 1-3%, polyalcohol amine 3-5%, second
Glycol 3-8%, triethanolamine 5-12%, molasses 3-5%, sodium phosphate 1-6%, sodium lignin sulfonate 1-3%, sorbierite 5-20%, sulphur cyanogen
Sour sodium 5-20%, remaining is water；
A kind of preparation method of the cement grinding aid of high reunion performance, which is characterized in that including following operating procedure:
(1) water is weighed according to the raw material proportioning of the cement grinding aid and sodium sulfocyanate is added in reaction kettle, open stirring, stirring
Appropriate oleic acid is added in the process, controlled at room temperature, mixing time is no less than 10 minutes；
(2) alcamine compound, ethylene glycol and sorbierite are weighed according to the raw material proportioning of the cement grinding aid, and is put into
In reaction kettle, stirring, dissolution are opened, appropriate aluminium chloride is added in whipping process, controlled at room temperature, mixing time is no less than
20 minutes；
(3) glycerol is weighed according to the raw material proportioning of the cement grinding aid, and is put into reaction kettle, open stirring, dissolution,
Controlled at room temperature, mixing time is no less than 30 minutes, is stood, is obtained cement grinding aid.
3. a kind of cement grinding aid of high reunion performance according to claim 1, it is characterised in that: the second
Glycol is recycling ethylene glycol.
The invention has the benefit that cement grinding aid and its preparation side of a kind of high reunion performance proposed by the present invention
Method, preparation principle is clear, and methodological science, compared with prior art, production cost are lower, and simple production process, volume are low, increase
Potent fruit is good, can improve cement and obtain reunion performance and yield, is suitble to large-scale production.
