METHOD OF SURFACE MODIFICATION OF RUBBERS

摘要

FIELD: manufacture of sealing friction units. SUBSTANCE: method comprises treating rubbers with solution of reactive agents in organic solvent and subsequently treating them at vulcanization temperature for 40-60 minutes. Reactive agents include 2-mercaptobenzthiazole and sulfur in combination with ultradispersive powder of solid lubricating materials at concentration of 4-5, 1-2 and 8- 10 wt parts respectively, and treatment of rubber is carried out for 5-7 hours. EFFECT: lower friction coefficient with respect to metals and higher wear resistance of rubbers. 2 ex, 2 tbl
