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.

生物炭作为填料在聚脲润滑剂中的应用

研究了在聚脲塑料润滑脂中使用植物来源的生物炭作为填料的可能性，并研究了其对其性能的影响。在润滑脂的制备中，III组石油和己二酸二辛酯用作分散介质，20%的双脲用作增稠剂。发现含有 5-15 重量份的润滑脂。与不含生物炭的样品相比，生物炭的百分比更好地减小了磨痕的直径并且具有更高的胶体稳定性。润滑脂的性能通过添加 1 wt. 聚异丁烯增稠剂 PIB 10 相对于分散介质的百分比。
