Abstract
The invention discloses bihexadecyl dimethyl ammonium chloride modified bentonite lubricating grease, which is prepared from the following raw materials in parts by weight: 60-90 parts of base oil, 8-25 parts of bihexadecyl dimethyl ammonium chloride modified bentonite, 1-10 parts of antirusting agent, and 0-10 parts of structure stabilizer. In the prior art, the product of bihexadecyl dimethyl ammonium chloride modified bentonite lubricating grease is not reported. With the adoption of the dual-long-chain quaternary ammonium salt modified bentonite, the layer structure of montmorillonite is effectively opened, the organobentonite lubricating grease of a dual-long-chain structure can form a stable trident structure during grease forming of the base oil, so that the shear stability of the lubricating grease is improved; and at the same time, the consistency of the lubricating grease is also related to the chain length, and can be dually regulated by the dosage and the chain length, so that the fineness of the lubricating grease is improved and the lubricating grease is expected to be used for high-speed bearing. The modified bentonite lubricating grease is good in shear stability, and ideal in abrasion resistance and scratch resistance.
Description
Technical field
The invention belongs to the modified alta-mud technical field of lubricating grease, specifically relate to a kind of bentonite-thickened grease with the Varisoft 432PPG modification and preparation method thereof.
Background technology
Organobentonite railway grease, heat-resistant quality is high, has mechanical stability and colloid stability preferably, is generally used for high temperature, heavy loading, slow-revving power lubrication.The quaternary ammonium salt that is used for Organic Modification of Bentonites at present in the prior art is single backbone; The consumption of viscosifying agent directly has influence on low temperature properties, Consistency and the shear stability of bentonite-thickened grease; Therefore organobentonite railway grease shows as duality: in rolling bearing, use for a long time on the one hand, bentonite-thickened grease is thinning easily and flow out; Show as on the other hand and be difficult to the engaging friction surface, not strong with the adhesive power of friction surface, so resistance to abrasion and resistance to marring are also not ideal, influence the use of bentonite-thickened grease in high speed roller bearing.How can provide a kind of shear stability good, resistance to abrasion and resistance to marring ideal modified alta-mud railway grease become the urgent demand of people.
Summary of the invention
The present invention provides a kind of shear stability good in order to overcome the deficiency that prior art exists, and resistance to abrasion and resistance to marring ideal are with bentonite-thickened grease of Varisoft 432PPG modification and preparation method thereof.
The present invention realizes through following technical scheme: a kind of bentonite-thickened grease with the Varisoft 432PPG modification, its raw material by following weight parts is formed: 60～90 parts of base oils, 8～25 parts of double hexadecyl Dimethyl Ammonium modified alta-muds, 1～10 part of rust-preventive agent, 0～10 part of structural stabilizing agent.
Said structural stabilizing agent is USP Kosher or terepthaloyl moietie.
The preparation method of said bentonite-thickened grease comprises the steps: base oil, rust-preventive agent and structural stabilizing agent are mixed and stir; Be warmed up to 80～90 ℃; Under disperseing fast, add double hexadecyl Dimethyl Ammonium modified alta-mud, fully shut down insulation behind the gelatinization 45min; Sampling inspection then, discharging packing after check touches the mark.
As preferred version of the present invention, said bentonite-thickened grease is made up of the raw material of following weight parts: 70～80 parts of base oils, 12～22 parts of double hexadecyl Dimethyl Ammonium modified alta-muds, 2～7 parts of rust-preventive agent, 2～8 parts of structural stabilizing agents.
As preferred plan of the present invention, said bentonite-thickened grease is made up of the raw material of following weight parts: 75 parts of base oils, 18 parts of double hexadecyl Dimethyl Ammonium modified alta-muds, 4 parts of rust-preventive agent, 5 parts of structural stabilizing agents.
The invention has the beneficial effects as follows: do not see product in the prior art at present with double hexadecyl Dimethyl Ammonium modified alta-mud railway grease; The present invention adopts two long chain quaternary modified alta-muds; Can effectively open the laminate structure of smectite; When in base oil, becoming fat, the organobentonite railway grease of two backbones can form three stable forked type structures, the shear stability that has improved railway grease; Consistency of grease is also relevant with chain length simultaneously, and consistency of grease can have been improved the sophistication of railway grease through adding dosage and chain length dual regulation, is expected to be used for high-speed bearing.Be that a kind of shear stability is good, resistance to abrasion and resistance to marring ideal modified alta-mud railway grease.
