<P>PROBLEM TO BE SOLVED: To provide a rubber composition for a conveyor belt capable of enlarging a loss factor tanδ while securing the hardness (Hs), modulus (M<SB>100</SB>, M<SB>300</SB>), rupture strengths (T<SB>B</SB>), and expansion (E<SB>B</SB>) at cutting which are demanded for a rubber for a conveyor belt. <P>SOLUTION: The rubber composition for the conveyor belt contains diene rubber (a) and polylactic acid resin (b), wherein the polylactic acid resin (b) is 2-12 pts.mass based on 100 pts.mass of the diene rubber (a). <P>COPYRIGHT: (C)2012,JPO&INPIT |
