RUBBER O-RING COMPOSITION FOR TRANSMISSION HAVING SUPERIOR PHYSICAL PROPERTIES WITHOUT ENVIRONMENTAL CONTAMINATION AND/OR HARMFUL EFFECT TO HUMAN BEING

摘要

PURPOSE: Provided is a rubber O-ring composition comprising cross-linkage agent and cross-linkage aid to remarkably improve physical property such as oil-resistance, heat-resistance without use of conventional rubber O-ring composition. CONSTITUTION: The composition comprises 0.5-5 parts by weight of active chlorinated cross-linkage agent, 0.5-3 parts by weight of cross-linkage aid, 50-55 parts by weight filler and 2-5 weight parts ageing-resistance relative to 100 parts by weight of acryl rubber. The active chlorinated cross-linkage agent is one or two or more selected from sulfur, sodium stearate and potassium stearate. The cross-linkage aid is one or two or more selected from stearic acid, calcium hydroxide and metal oxides.
