Description
Technical field
The present invention relates to a kind of sulfonate, more particularly to a kind of over base sulfosalt suitable for grease.
Background technology
Complex calcium sulfonate grease is the new grease of a class, with excellent extreme pressure property, abrasion resistance, water resistant
Performance, resistance to saltfog energy and Corrosion Protection, and dropping point height, heat stability are good, are widely used in automobile, iron and steel, mine, papermaking
Etc. industry.
Complex calcium sulfonate grease adopts newton body sulfoacid calcium for raw material, and non newtonian is converted in the presence of active hydrogen
Body sulfoacid calcium.Calcium Carbonate wherein in newton body sulfoacid calcium is unbodied, and the Calcium Carbonate in complex calcium sulfonate grease
For calcite type, therefore to prepare the process of grease be actually to be converted into the unformed Calcium Carbonate in newton body sulfoacid calcium
Calcite type calcium carbonate, and the process of non-newtonian fluid sulfoacid calcium is ultimately formed, therefore, select suitable newton body sulfoacid calcium very
It is important.

559、US4,604,219、US4,879,053、US4,929,373、US4,810,396、EP0,515,062、EP0,949,322、
US6,015,778, US4,560,489 etc., its preparation method is generally：With alkyl benzene sulphonate or alkyl benzene calcium sulfonate as original
Material, adopts all kinds of low mass molecule alcohols for accelerator, and being passed through carbon dioxide carries out carbonation reaction, and reaction heats up after terminating and is dehydrated, Jing
Post processing obtains calcium sulfonate with high base number.Calcium sulfonate with high base number in above-mentioned patent（Base number is more than 300mgKOH/g）With it is overbased
Sulfoacid calcium（Base number is more than 395mgKOH/g）, it is mainly used in I. C. engine oil and iundustrial oil, plays solubilising, dispersion, neutralization, anti-
The effect such as rust.
Grease sulfoacid calcium requires that the Calcium Carbonate in sulfoacid calcium is unformed, is easy to conversion under certain condition, obtains
Grease has preferable high and low temperature performance, extreme pressure anti-wear, colloidal stability and water-resistance.And the sulphur used in lubricating oil
Sour calcium is required with excellent detergency, dispersibility and acid neutralization performance.Two kinds of products are different for the requirement of sulfoacid calcium,
Therefore, prepare grease with the existing newton body sulfoacid calcium in lubricating oil to there are problems that, for example：Sulfoacid calcium turns
Change speed is slow or changing effect is bad, and the high-temperature behavior and other performance of the grease after conversion can not meet requirement, so
Limit sulfoacid calcium further applying in grease.
