<P>PROBLEM TO BE SOLVED: To provide a heat storage rubber material nearly free from reduction of a heat storage function when repetitively used, leakage of a latent heat storage material included in a microcapsule and deterioration of the rubber material and change of the shape thereof. <P>SOLUTION: In the heat storage rubber material containing the microcapsule and the rubber material, the latent heat storage material is a compound selected from the group composed of a paraffin having ≥35°C melting point, a higher alcohol having ≥45°C melting point, an ester compound having ≥30°C melting point and represented by general formula (I): R1-COO-R2 and an ester compound having ≥2°C melting point and represented by general formula (II): R3-COO-R4. In general formula (I), R1 denotes a ≥16C hydrocarbon group and R2 denotes a 1-6C hydrocarbon group. In general formula (II), R3 denotes a ≥8C hydrocarbon group and R4 denotes a ≥8C hydrocarbon group. <P>COPYRIGHT: (C)2011,JPO&INPIT |
