Abstract
The present invention relates to lubricating grease which uses high-viscosity mineral oil as base oil and uses calcium alkylbenzenesulfonate with a high base number, fatty acid, orthoboric acid glacial acetic acid and calcium hydroxide as thickeners, particularly composite calcium sulfonate lubricating grease. The production process of the composite calcium sulfonate lubricating grease comprises: the base oil, the calcium alkylbenzenesulfonate with a high base number, the glacial acetic acid, the orthoboric acid and the calcium hydroxide are added according to the proportion of the specified part by weight to be converted and saponified at the temperature of 100DEGC; then, the fatty acid is added to be compounded, high-temperature compound refining is carried out when the maximum temperature is raised to more than 180DEGC, and an antioxidant, an extreme pressure agent and an oiliness agent are added when the temperature is reduced to 110 DEGC; finally, a homogenizer is used for post-treatment, filtration and packaging. The composite calcium sulfonate lubricating grease has the advantages of outstanding high-temperature property, high shear stability, excellent water resisting property, high extreme pressure property, good adhesion property and good integrative water-proof property. When containing 20% of water, the composite calcium sulfonate lubricating grease has an outstanding anti-rust property and an excellent extreme pressure property to bearings, and the composite calcium sulfonate lubricating grease is suitable for the working condition of rolling mill bearings.
Description
Technical field
The present invention relates to a kind of is base oil with the high viscosity mineral oil, is the lubricating grease of viscosifying agent with high base number calcium alkylbenzenesulfonate, lipid acid, boric acid, glacial acetic acid and calcium hydroxide, composite calcium sulfonate grease lubricant.
Background technology
Fast development along with metallurgical industry, the equipment work condition of Steel Mill is more and more harsher, the equipment bearing of medium-sized factory, bar factory, medium plate mill, hot rolled strip factory mostly at high temperature, at a high speed, move under the environment of heavy loading, Duo Shui, many dirt, this has just proposed higher requirement to the used PERFORMANCE OF GREASES of steel rolling equipment bearing.
The lubricating grease that is used for the steel rolling equipment bearing is many at present based on extreme pressure lithium base fat or extreme pressure compound lithium, but because this lipoid soap structure is limit, fat in use often occurring is washed away by water and runs off or thinning phenomenon, so just brought inconvenience to the user, short as life cycle, stuffing is safeguarded frequent, and bearing causes wearing and tearing because of lacking enough lubricating grease easily, or get rusty because of big entering of water gaging, therefore easily have lubricated accident.So just influenced normal production, the financial loss that causes because of break down maintenance is surprising in Steel Mill.
Summary of the invention
The purpose of this invention is to provide a kind of viscosifying agent is based on the high base number calcium alkylbenzenesulfonate; and with the calcium soap compound lubricating grease composite calcium sulfonate grease lubricant of lipid acid, glacial acetic acid, boric acid; through the evidence of how tame Steel Mill; successfully solved the difficult problem of Steel Mill with fat; it is not thinning that this fat is met water; do not run off; duration of service and maintenance time have been prolonged; to the antirust excellent protection that provides of bearing; wearing and tearing never take place in bearing and influence is produced, to bearing high loading, high temperature, at a high speed, the operating mode of many water is very suitable.
