Background
The thermoplastic dynamic vulcanized rubber TPV is a rubber-plastic alloy formed by dispersing a rubber phase in a plastic phase and dynamically vulcanizing. TPV has the characteristics of traditional rubber and plastic, is in a rubber state when in use and is in a plastic state when in processing, greatly reduces pollution and energy consumption in the rubber processing process, and fully meets the environmental protection requirements of low-energy-consumption processing and repeatable processing. The acrylate rubber is an elastomer obtained by copolymerizing acrylate serving as a main monomer, the main chain of the acrylate rubber is a saturated carbon chain, and the side group of the acrylate rubber is a polar ester group. The special structure endows the automobile with a plurality of excellent characteristics, such as heat resistance, aging resistance, oil resistance, ozone resistance, ultraviolet resistance and the like, the mechanical property and the processing property of the automobile are superior to those of fluororubber and silicone rubber, the heat resistance, the aging resistance and the oil resistance of the automobile are superior to those of nitrile rubber, the automobile sealing material is widely applied to various high-temperature and oil-resistant environments, and becomes a sealing material which is intensively developed and popularized in the automobile industry in recent years, particularly a high-temperature resistant oil seal, a crankshaft, a valve rod, a cylinder gasket, a hydraulic oil conveying pipe and the like. The traditional TPV is mostly made of acrylic rubber EPDM, polyolefin resins PP and PE, and the polyolefin TPV can swell and even dissolve after contacting with grease chemicals, so that the physical properties are seriously deteriorated. The TPV material prepared by blending and dynamically vulcanizing the acrylate rubber and the polar thermoplastic elastomer can fill the market demands for oil-resistant, temperature-resistant and moisture-resistant thermoplastic elastomers.
