Title:
ゴム組成物と有機塩硬化剤
Document Type and Number:
Japanese Patent JP2013515845
Kind Code:
A
Abstract:
A rubber composition comprising a metal salt of a carboxylic acid used as a curing agent, a highly unsaturated dieene rubber, a filler and a sulfur vulcanization system of between 0.5 phr and 8 phr of sulfur and at least one vulcanization accelerator. Particular embodiments may further include between 1 phr and 6 phr of a metal salt of a carboxylic acid that increases a tear index of the cured elastomer composition by at least 50 percent as compared to a similar cured elastomer composition, such similar cured elastomer composition being different in composition only in that it (1) lacks the metal salt of a carboxylic acid and (2) has an increased amount of the sulfur vulcanization system at about the same sulfur to accelerator ratio to maintain a 10% modulus of elongation at 23 0C to within 15% of the modulus of the cured rubber composition.
