The invention relates to a rubber composite material using cardanol glycidyl ether modified silica. The rubber composite material using the cardanol glycidyl ether modified silica comprises rubber, silica and cardanol glycidyl ether, and can further comprise a silane coupling agent. Structural characteristics of cardanol glycidyl ether are used, so that the cardanol glycidyl ether modifies the silica through epoxy group grafting, furthermore, unsaturated long carbon chain hydrocarbon can be crosslinked with the rubber molecular chains, and the cardanol glycidyl ether has the function of modifying the silica similar to the conventional silane coupling agent. Compared with the method of using the silane coupling agent for modifying the silica, the cardanol glycidyl ether can modify the silica under mild conditions to greatly reduce the modification cost and energy consumption of the silica. In addition, water is the only reaction by-product when the cardanol glycidyl ether modifies the silica, and other small organic molecules are not produced, thereby being of great help to reduce VOC emissions during the modification process of the silica.
