Abstract

1/1 resumo composição de borracha para bandas de rodagem de pneus a presente invenção é uma composição de borracha para bandas de rodagem de pneus, da qual a temperatura da posição de pico da curva de temperatura de tand é -16,0ºc ou mais elevada e -6,0ºc ou mais baixa, tand na posição de pico é maior que 1,13, tand a 0ºc é 0,95 ou mais, e o valor obtido por dividir o valor absoluto da diferença entre tand a -5ºc e tand a 5ºc pela diferença de temperatura entre 5 ºc e 5ºc {|(tand a -5ºc) – (tand a 5ºc)|/10} (/ºc) é menor que 0,045/ºc. a invenção também é uma composição de borracha contendo um componente de borracha que contém pelo menos dois tipos de borrachas de copolímero de estireno- butadieno diferindo no teor de estireno ligado no mesmo, e um material de enchimento; a composição sendo uma composição de borracha para bandas de rodagem de pneu, na qual a diferença entre o teor de estireno ligado st(a) da borracha de copolímero de estireno-butadieno (a) tendo um teor de estireno ligado elevado e o teor de estireno ligado st(b) da borracha de copolímero de estireno-butadieno (b) tendo um teor baixo de estireno ligado {st(a) – st(b)} é de 6 a 22% por massa, e do qual tand a 0ºc é 0,95 ou mais, e o valor obtido por dividir o valor absoluto da diferença entre tand a -5ºc e tand a 5ºc pela diferença de temperatura entre -5ºc e 5ºc {|(tand a -5ºc) – (tand a 5ºc) |/ºc} é menor que 0,045/ºc. a invenção provê as composições de borracha para bandas de rodagem de pneus que atendem mais altamente tanto a propriedade de geração baixa de calor como ao desempenho de frenagem úmida.
