Abstract
The invention discloses a vertical mill slag grinding aid and a preparation method thereof. The slag grinding aid comprises the following components in percentage by weight: 5 to 40% of polyol amine, 10 to 60% of polymeric polyol, 5 to 40% of polyol, 3 to 20% of inorganic salts, and the balance being water. The provided preparation method is suitable for the production of vertical mill slag grinding aid. The slag yield is increased by 5 to 20%. The activity indexes of slag are increased to different degrees. The fineness (residue on sieve) and specific surface area of mineral powder are prominently improved, and the performance of cement is not influenced. The preparation method can improve the fluidity of mineral powder, thus reduces the phenomenon of over grinding, improves the powder selecting efficiency, and prominently increases the content of fine particles with a size less than 32 [mu]m. The provided preparation method improves the grinding efficiency of grinding machine, reduces the wear degree of grinding machine, thus reduces the maintenance cost and production cost, and has a high performance/cost ratio. Moreover, the production technology and equipment are simple and practical.
Description
Technical field
The present invention relates to slag and manufacture field, in particular, relate to a kind of instantly grinding scoria grinding aid and preparation method thereof.
Background technology
Slag is as a kind of material with excellent activity, it is widely used in cement and concrete, containing crystalline solid and vitreous body in slag, the former belongs to inert component, the latter belongs to active component, how potential the more hydraulicity of active component content be also more good, but grindability is relatively more poor, therefore no matter separate grinding is ball milling or the energy consumption that Vertical Mill consumes is higher, in actual industrial production, the grinding effect of slag can be improved by two kinds of methods: one is to improve existing equipment, but it puts into and maintenance cost is high；Another kind is to mix grinding aid in slag milling, it is characterized in putting into too many expense, and can reach to improve grinding fineness, improve physical and chemical performance, make the advantages such as the reduction of material particles surface free energy, reduction grinding pow consumption and cost of use are low, therefore, current many slag millings stand in and add grinding aid in slag milling process to improve grinding effect and activity.
At present, market exists polytype slag grinding aid special, but it is all that tradition grinding aid is improved or directly used, this type of grinding aid is for ball mill, residence time of material is only had to the Vertical Mill of ball mill 1/5th, after using this type of grinding aid, it is not enough that yield and activity improve upward stability.
Summary of the invention
Present invention aims to the technical deficiency of opposition ore grinding slag-grinding aid at present, a kind of instantly grinding scoria grinding aid is provided, based on multiple slag characteristic, by the optimization to raw material selection and grinding aid formula, prepare can high instantly grinding scoria production capacity and improve slag reactivity index, and produce and the cheap grinding aid of use cost.
For achieving the above object, present invention employs following technical scheme:
A kind of instantly grinding scoria grinding aid, this slag grinding aid by constituent mass percentage ratio is: polyhydric alcohol amine 5%～40%, polymerized polyalcohol 10%～60%, polyhydric alcohol 5%～40%, inorganic salt 3%～20%, water surplus.
Preferably, described polyhydric alcohol amine is one or more in triethanolamine, triisopropanolamine, diethanol monoisopropanolamine.
Preferably, described polymerized polyalcohol is polyglycereol, one or more in polymeric alcohol.
Preferably, described polyhydric alcohol is one or more in ethylene glycol, propylene glycol, glycerol, diethylene glycol, triethylene glycol.
Preferably, described inorganic salt is one or more in Nacl, calcium chloride, sodium sulfate, sodium silicate, sodium tripolyphosphate, sodium hexameta phosphate, sodium polyphosphate.
It is mix 0.025%～0.2% in cement material per ton that described slag grinding aid puts into the amount of cement.
The preparation method of a kind of instantly grinding scoria grinding aid, comprises the steps:
1) institute's water consumption is joined in agitator tank；
2) be added to the water formation inorganic salt solution by inorganic salts；
3) polyhydric alcohol is joined above-mentioned steps 2) in inorganic salt solution；
4) polymerized polyalcohol is joined step 3) in mixed liquor；
5) polyhydric alcohol amine is joined step 4) in mixed liquor；
6) above-mentioned raw materials add complete, carry out uniform stirring at normal temperatures after 2-4 hour, filter finished product.
Compared with prior art, the present invention has the following advantages and beneficial effect: preparation method of the present invention is applicable to the production of instantly grinding scoria grinding aid, slag yield can be increased and reach 5%～20%, the activity index of slag all obtains raising in various degree, fineness (tailing over) and the specific surface area of breeze can be significantly improved, and cement performance thing is had no adverse effects.Preparation method of the present invention improves the mobility of breeze thus reducing grinding phenomenon, improves grinding efficiency, dramatically increases the fine particle content of below 32um.Preparation method of the present invention improves the grinding efficiency of grinding machine, decreases the extent of deterioration of grinding machine, reduces maintenance and the maintenance cost of equipment, to reducing production cost, has bigger cost performance.The advantages such as the grinding aid of the present invention, production technology and preparation are simple, practical.
