- Abstract
The possibility of using biochar of plant origin as filler in polyurea plastic greases was studied, and its effect on their performance was investigated. In the preparation of the greases petroleum oil of group III and dioctyl adipate were used as dispersion medium, and 20% diurea was used an thickener. It was found that greases containing 5-15 wt. % of biochar reduce the diameter of the wear scar better and have higher colloidal stability than samples not containing biochar. The performance of the grease is improved by the addition of 1 wt. % of polyisobutylene thickener PIB 10 to the dispersion medium.
