Abstract
The invention discloses an alumina liquid grinding aid which comprises the following components in weight percentage: mannitol 20-30 %, sorbitol 5-20 %, sodium hexametaphosphate 3-5 %, sodium dodecyl benzene sulfonate 0.01-0.05 %, and the balance of water, the total amount is 100%. According to the alumina liquid grinding aid provided by the invention, neutral polyhydroxy alcohol grinding aid components including mannitol and sorbitol, which cannot react with the alumina to affect the using effect of the grinding aid, are used, so that the material fluidity is remarkably increased, grinding efficiency of a grinding machine is increased, and the output per machine-hour is increased; dispersants with high adsorption strength including hexametaphosphate, and sodium dodecyl benzene sulfonate can obviously avoid the powder body agglomeration phenomenon, improve alumina particle grading, increase micro powder particle content, and increase sintering activity of the alumina powder body.
Description
Technical field
The present invention relates to a kind of aluminum oxide liquid grinding aid and preparation method thereof, belong to the grinding aid technical field.
Background technology
In the grinding process of aluminum oxide, big especially to the loss of the energy, facts have proved, in the crushing process of aluminum oxide, add suitable grinding aid and can improve grinding output, cut down the consumption of energy.Liquid grinding aid base-material commonly used on the normal market of order has: alcohols, alcamines, lipid acid and ester, sulfonated lignin etc.These grinding aids all have lubrication, and when material was pulverized, grinding aid is given full play to two effects greatly: one reduced granule strength and hardness, promotes cracked, the raising grindability; The 2nd, reduce adhesion and the cohesion of particle, prevent the adhesion of intergranular conglomeration and particle and grinding element, improve the flowability of material.The mechanism that this mainly reduces hardness and regulate the flow of slurry sex change based on absorption.Therefore grinding aid can significantly improve the grinding fineness of material, significantly shortens the grinding time, and then reaches the raising mill efficiency, reduces the purpose of power consumption.
Chang Yong aluminum oxide grinding aid is generally the grinding aid of alcaminess such as trolamine, tri-isopropanolamine in the market, since the amphoteric character of aluminum oxide can with weakly alkaline alcamines material generation neutralization reaction, influence the effect that the alcamines material plays in grinding process, reduced the dispersiveness between powder granule, the aluminium oxide granule intergranular power that attracts each other is increased, the trend of spontaneous reunion strengthens, the alumina particle surface energy increases, so it is not obvious to cause unit-hour output to increase, alumina particle grating reduction etc.
So market demand seeks not make a kind of aluminum oxide liquid grinding aid with the neutral substance of aluminum oxide reaction as the main component of grinding aid, thereby better brings into play the effect of grinding aid in aluminum oxide grinding process.And poly-hydroxy alcohols and aluminum oxide can not react, and are the topmost compositions of preparation aluminum oxide grinding aid.
Summary of the invention
Purpose: for solving the deficiencies in the prior art, solve existing common liq grinding aid loses the original effectiveness of grinding aid with the aluminum oxide reaction in the grinding of aluminum oxide problem, the invention provides a kind of aluminum oxide liquid grinding aid and preparation method thereof.
Technical scheme: for solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of aluminum oxide liquid grinding aid, it consists of: N.F,USP MANNITOL 20-30%, sorbyl alcohol 5-20%, Sodium hexametaphosphate 99 3-5%, Sodium dodecylbenzene sulfonate 0.01-0.05%, and surplus is water, total amount 100%; Described per-cent is mass percent.
The preparation method of aluminum oxide liquid grinding aid, the steps include: in reactor, to inject water according to formula rate, add Sodium hexametaphosphate 99, Sodium dodecylbenzene sulfonate while stirring, stir 15min, add N.F,USP MANNITOL, sorbyl alcohol stirring 10min again, through behind the 150 order stainless steel impurity screenings, namely obtain aluminum oxide liquid grinding aid product again.
Beneficial effect: in the aluminum oxide liquid grinding aid provided by the invention, use neutral polyhydroxy-alcohol grinding aid composition N.F,USP MANNITOL, sorbyl alcohol, can not influence the grinding aid result of use with the aluminum oxide reaction, can significantly increase material fluidity, improve mill grinding efficiency, improve mill hourly output; The sodium hexametaphosphate dispersant, the Sodium dodecylbenzene sulfonate that contain high adsorption strength can obviously solve the powder reuniting phenomenon, improve the grating of alumina particle, increase micro powder granule content, improve alumina powder jointed sintering activity.
Embodiment
Below in conjunction with example the present invention is done and to specify:
Embodiment 1: a kind of aluminum oxide liquid grinding aid, composed as follows:
N.F,USP MANNITOL 25%
Sorbyl alcohol 10%
Sodium hexametaphosphate 99 3%
Sodium dodecylbenzene sulfonate 0.01%
Surplus is water, and total amount is 100%.
The preparation method of described aluminum oxide liquid grinding aid, step is: inject water according to formula rate in reactor, add Sodium hexametaphosphate 99, Sodium dodecylbenzene sulfonate while stirring, stir 15min, add N.F,USP MANNITOL, sorbyl alcohol stirring 10min again, through behind the 150 order stainless steel impurity screenings, namely obtain aluminum oxide liquid grinding aid product again.
Embodiment 2 to embodiment 4:
Press the method for each component concentration repeated experiments embodiment 1 of appointment in the following table 1, obtain the aluminum oxide liquid grinding aid product of different components content respectively:
Table 1
| Component | Embodiment 1 | Embodiment 2 | Embodiment 3 | Embodiment 4 |
| N.F,USP MANNITOL (%) | 25 | 20 | 30 | 20 |
| Sorbyl alcohol (%) | 10 | 15 | 5 | 20 |
| Sodium hexametaphosphate 99 (%) | 3 | 5 | 5 | 4 |
| Sodium dodecylbenzene sulfonate (%) | 0.01 | 0.02 | 0.03 | 0.05 |
| Obtain | Product 1 | Product 2 | Product 3 | Product 4 |
With the aluminum oxide liquid grinding aid product that makes among the embodiment 1 to embodiment 4, be 0.03% of aluminum oxide quality at addition content, add the contrast experiment of aluminum oxide liquid grinding aid and common grinding aid, experimental result is as shown in table 2:
Table 2
As can be seen, the aluminum oxide liquid grinding aid that the invention provides and prepare is compared with common grinding aid, can not influence the grinding aid result of use with the aluminum oxide reaction, can not cause the slimeball phenomenon, has improved the mill efficiency of grinding machine; Can significantly increase material fluidity, improve mill grinding efficiency, improve mill hourly output, unit-hour output increases by 30%; The sodium hexametaphosphate dispersant, the Sodium dodecylbenzene sulfonate that contain high adsorption strength can obviously solve the powder reuniting phenomenon, improve the grating of alumina particle, and the 5.13um grain composition increases by 25%.
