Phase change heat storage rubber comprises the following components in parts by weight: 20-70 parts of rubber and 10-68 parts of modified phase change powder. The phase change heat storage rubber contains a proper amount of the modified phase change powder, so that the phase change heat storage rubber has excellent heat absorption and heat storage performance, the phase change enthalpy reaches 15-200 J / g, the specific heat capacity exceeds 2.0 J / g.K, the requirements of batteries and capacitors on heat absorption and heat storage performance are met, the modified phase change powder has a heat absorption and energy storage function, and due to large phase change enthalpy value and slow temperature rise, rubber can absorb more heat. The phase change powder is modified by a modifier. The modifier is large specific surface area powder containing micropores. After mixing with the modifier, the specific surface area is increased. The powder contains a large number of micropores. The phase change powder enters the micropores and is firmly locked, so that the phase change powder cannot be freed from the micropores under high temperature conditions. The stability and sustainability of heat storage of the phase change heat storage rubber are 4-5 times that of similar products on the market. Even if the phase change powder is used for a long time, the heat storage performance of the phase change heat storage rubber is reduced by no more than 2-3%.
