<p>PURPOSE: To improve thermal stability and wear resistance by forming an outer coating body of a roll from a crosslinked elastomer random copolymer of dimethylsiloxane and diphenylsiloxane, zinc oxide particles, graphite particles and cerium dioxide particles having specified size. CONSTITUTION: This roller consists of a core and an outer coating body. The outer coating body consists of a crosslinked elastomer random copolymer of dimethylsiloxane and diphenylsiloxane and three additives. These additives are 40 to 55wt.% zinc oxide particles having 100 to 500nm diameter, 5 to 10wt.% graphite particles in which almost all particles have <10μm diameter, and 1 to 5wt.% cerium dioxide particles having 0.2 to 3.0μm diameter. Thereby, thermal stability and wear resistance of the coating body on the roller can be improved.</p> |
