Description
T106 detergent is widely use for blending internal combustion engine oils for each grade and industrial lubricants as the antirust agent. T106 also has some dispersity. The alkaline calcium sulfonate can neutralize the oxygenated acid of the lubricant and fuel oil oxidized, preventing them from condensation further so that coatings and sludge are reduced. It has the excellent detergency, and can remove the coatings and deposit,increasing solubility and making them disperse in the lubricant.

Key Performance Benefits 
1. Good high-temperature detergency 
2. Strong acid neutralization ability 
3. Excellent antirust performance  
4. Good high-temperature stability 
5. Good Antifoam performance 
6. Good dispersity

Application:
Used for blending internal-combustion engine oils
Used for blending internal-combustion engine oils of each grade 
Used for blending industrial lubricants as the antirust

Recommended Dosage
The dosages of T106D detergent generally recommended to blend lubricants are 1.5%-3.0%

Packing: The product is packed in 200 liter metal drums (net weight: 200Kg/drum).
Storage: Keep the temperature not higher than 75°C. For long-term storage, the suggested temperature is lower than 45°C. The product should be avoiding from strong oxidants.

Description

A kind of high-performance complex calcium sulfonate grease and preparation method thereof Technical field The present invention relates to a kind of lubricating grease and preparation method thereof, especially a kind of calcium sulfonate grease and preparation method thereof that meets, belongs to technical field of chemistry. Background technology Complex calcium sulfonate grease is a type high temp multipurpose grease, this lubricating grease does not add any additive and just has excellent extreme pressure and antiwear behavior, water repelling property, salt fog resistance performance, protection against corrosion and rust-preventing characteristic, also there is good high temperature performance simultaneously, mechanical stability, colloid stability and oxidation stability, be called as " high-efficiency lubricating fat of new generation ".The 's, abroad just starts as viscosifying agent, to prepare lubricating grease by calcium sulphonate, but because its thickening ability is low, oil soluble newton body calcium sulphonate solution thickening ability is very little, so fail effectively to be promoted.After the seventies, people are by the improvement of p-sulfonic acid calcium, and further with the overbasic complex calcium sulfonate greases of compound preparation such as lipid acid and borate, overcome gradually the feature of original product, in performance, had very large improvement, and there is the patented technology of some overbased Calcium Sulfonate Complex Grease to deliver, as US, US, US, US, US.Wherein, although the lubricating grease of preparing in US is had outstanding performance at aspects such as high thermal resistance, shear stabilities, its shortcoming is that viscosifying agent content is high, causes temperature pumping poor, has hindered the wide range of industrial applications of this fat; US, it is that the calcium sulphonate of 400 mgKOH/g is prepared overbased Calcium Sulfonate Complex Grease that US and US have proposed to adopt total basicnumber, but the lubricating grease that they are prepared is shorter work-ing life; And US adopts alcohols, ethers, after having transformed, transforming agent is directly discharged in atmosphere, causes environmental pollution, and has the problems such as conversion is not thorough, and conversion process is unstable.Since the nineties, complex calcium sulfonate grease formally put goods on the market, its Application Areas has expanded to the industries such as iron and steel, metallurgy, paper pulp, fresh water and seawater transportation, railway, generating, automobile production, building, food machinery, caused the extensive concern of domestic and international lubricating grease industry, its output abroad especially Canada, the U.S. is with 15% speed increment every year on average.But the industrial application of calcium sulfonate complex grease is still in the starting stage at home, though there are indivedual producers to form small-scale industrial production, but also as a large series products, in industrial widespread use, do not promote, a lot of comparatively harsh lubricated operating mode occasions, go back dependence on import calcium sulfonate grease.Applicant understands rear discovery: though domestic, have technical literature to describe this class preparation of greases method, as CNA, CN, CNA, CNA, but also there is certain defect, wherein, CNA is in order to reduce preparation cost, and adopting base number is the calcium alkylbenzenesulfonate of 300 mgKOH/g, consumption is higher, and cost is corresponding raising also; And in the preparation technology of CNA, contain organic carbamide compound, and by adding organic carbamide compound to enhance product performance in overbased Calcium Sulfonate Complex Grease, production technique more complicated, technology controlling and process point is many, and the production time is long, and raw material is poisonous.In CNA, adopting base number is that the calcium sulphonate of 250-320mgKOH/g is as the main raw material of complex calcium sulfonate grease, and consumption is up to 60%(weight percentage), and along with total basicnumber is greater than the low-cost listing of ultrahigh basicity calcium sulphonate of 380mgKOH/g, developing the more complex calcium sulfonate grease of best performance has been imperative.Although adopted the calcium sulphonate of overbased (TBN400) in CNA, cost is still higher, and the package stability of product is poor, and work-ing life is shorter.In addition, also have some patents, the technical scheme providing as CNA exists conversion not thorough, and transforms less stable; The preparation technology that CNA provides can not guarantee CaCO 3in fat, fully disperse, the fat dropping point of preparation is on the low side, and bearing runs off larger; CNA can not effectively solve complex calcium sulfonate and the case-hardened problem of lubricating grease.In these patents, all adopt boric acid as mineral acid, not only bearing wastage is larger, exists and transforms not thorough and transform poor stability, technology controlling and process is required to the shortcomings such as higher, and cost is higher. The viscosifying agent system of calcium sulfonate complex grease is mainly with non-newtonian fluid high alkaline calcium sulfonate, and wherein calcium carbonate exists with the form of calcite crystal formation, and the performance of p-sulfonic acid calcium grease plays conclusive effect.If calcium carbonate containing quantity not sufficient or calcium carbonate wherein from the unformed calcite crystal formation that is not converted into completely, lubricating grease can be partially soft, high-temperature behavior is not good, the sintering load of lubricating grease is on the low side.Therefore, the key of preparing complex calcium sulfonate grease is the conversion of newton's height alkaline sulfoacid calcium, how to make high alkaline calcium sulfonate transform more complete, reduces the consumption of high alkaline calcium sulfonate, thereby effectively reduce costs and enhance product performance, becoming the technology focus that these those skilled in the art pay close attention to.In addition, good compound prescription and preparation technology have to the grease of calcium sulfonic acid after changing mutually the supplementary function being highly profitable, but these to be all prior art be short of. Summary of the invention The object of the invention is the defect existing for prior art, a kind of high-performance complex calcium sulfonate grease of proposition, has high dropping point, good antirust and non-corrosibility, extreme pressure anti-wear and good mechanical stability, and place for a long time non-sclerous, the feature of long service life.
