Wollastonite-based high-temperature resisting lubricant and preparation method and application thereof

Abstract

The invention discloses a wollastonite-based high-temperature resisting lubricant and a preparation method and application thereof. Taking water as a solvent, the wollastonite-based high-temperature resisting lubricant is prepared from the following components in parts by weight: 10-40 parts of wollastonite powder, 1-5 parts of glass fiber, 1-10 parts of sodium polyphosphate, 1-3 parts of polyethylene glycol and 0.1-1 part of a thickening agent. The preparation method of the wollastonite-based high-temperature resisting lubricant comprises the following steps: step one, the water and the polyethylene glycol are added into a reaction kettle, and then stirring is conducted for 5-10 min; step two, the wollastonite powder, the glass fiber, the sodium polyphosphate, a dispersant and an antifoaming agent are added into the reaction kettle in sequence, and then stirring continues being conducted for 60-90 min; and step three, a preservative and the thickening agent are added into the reactionkettle, then stirring is conducted for 60-90 min, and thus the wollastonite-based high-temperature resisting lubricant is obtained. The wollastonite-based high-temperature resisting lubricant has theadvantages of health, environmental protection and good stability, has extremely excellent lubrication performance under the high temperature condition, and is suitable for being used for hot-rolledseamless steel pipes.

Description

technical field [0001] The invention relates to the technical field of lubricants, in particular to a wollastonite-based high-temperature resistant lubricant and a preparation method and application thereof. Background technique [0002] Mandrel is the most important hot forming tool in the production process of seamless steel pipe. In the forming process of continuous rolling seamless steel pipe, the high temperature and high pressure resistant lubricant is sprayed on the mandrel, which can not only prolong the service life of the mandrel, increase the elongation coefficient, but also reduce the rolling pressure and power consumption, and even Reduce or avoid tandem mill accidents. Graphite has a flaky crystal structure and has good lubricating properties. Moreover, it also has good electrical conductivity, thermal conductivity, wear resistance, pressure resistance, and temperature resistance, so it is often widely used in the machinery industry to manufacture various lub...

Problems solved by technology

This high-temperature lubricant has been used in industry, but its friction coefficient is relatively high, and the maximum extreme pressure it can withstand is relatively low, so it cannot completely replace the traditional high-temperature graphite lubricant. In addition, the chemical stability of this high-temperature lubricant is relatively low. Poor, stratification will inevitably occur after one month of storage, and it is difficult to store for a long time
