Abstract

The invention relates to a high-temperature-oil-resistant thermoplastic elastomer. The high-temperature-oil-resistant thermoplastic elastomer is prepared from the following raw material components in parts by weight: 8-10 parts of toughening master batch, 20-30 parts of oil-resistant master batch, 5-8 parts of polypropylene powder and 40-50 parts of acrylonitrile-butadiene rubber powder, wherein the toughening master batch is prepared from the following raw material components in parts by weight: 10-20 parts of linear low density polyethylene, 30-40 parts of methyl vinyl silicone rubber, 30-40 parts of a toughening agent, 1-2 parts of a radiation crosslinking agent and 10-15 parts of a reinforcing agent; and the oil-resistant master batch is prepared from the following raw material components in parts by weight: 80-100 parts of nitrile silicone rubber, 3-5 parts of a lubricating agent, 10-20 parts of a reinforcing agent, 10-20 parts of a filling agent, 1-2 parts of a radiation crosslinking agent and 3-5 parts of a thermal controller. A preparation method of the high-temperature-oil-resistant thermoplastic elastomer comprises the following steps: firstly respectively preparing the toughening master batch and the oil-resistant master batch, then mixing the polypropylene powder, the acrylonitrile-butadiene rubber powder, the toughening master batch and the oil-resistant master batch in required ratio, extruding, and granulating, so that the high-temperature-oil-resistant thermoplastic elastomer is obtained. The high-temperature-oil-resistant thermoplastic elastomer not only can continuously resist to high-temperature oil but also can be recycled.
