PURPOSE: To obtain a non-black rubber composition capable of exhibiting excellent abrasion resistance and stain resistance in curing and suitable in formation of coating layer of a paper feeding roll by blending a rubber with a specific amount of zinc oxide. n CONSTITUTION: The non-black rubber composition obtained by blending (A) 100 pts.wt. rubber (preferably natural rubber, styrene butadiene rubber or polybutadiene rubber) with (B) 15-45 pts.wt. zinc oxide having 0.01-0.8μm granule size and further as necessary curing agent, curing accelerator, softening agent, aging preventing agent and other filler, etc. The paper feeding roll obtained by coating the outer circumference of shaft core material with the above- mentioned non-black rubber composition and having excellent abrasion resistance and resistance to stain of paper. n COPYRIGHT: (C)1990,JPO&Japio |
