Abstract

The invention relates to a high-performance TPV material and a continuous automatic production method thereof. The high-performance TPV material comprises the following components: ethylene-propylene-diene monomer, atactic polypropylene, homo-polypropylene, a filler, a plasticizer, an anti-aging agent, an anti-ultraviolet agent, a color masterbatch, a slipping agent, a vulcanizing agent and an auxiliary vulcanizing agent. The production method comprises the following steps: 1, crushing a raw ethylene propylene diene monomer bag by adopting a crusher in a mechanochemical normal-temperature crushing manner to obtain particles with particle sizes of 5-12 mm, and conveying a separant through a screw rod at the same time; 2, conveying the particles and the separant to an upper auxiliary material bin of an extruder; 3, continuously conveying the ethylene-propylene-diene monomer particles, the atactic polypropylene, the homo-polypropylene, the filler, the anti-aging agent, the anti-ultraviolet agent, the color master batch and the slipping agent to a feeding hopper of the extruder through a feeding screw; 4, feeding the plasticizer into the extruder through a lateral feeding port behind the hopper of the extruder by adopting a liquid metering device; 5, feeding the vulcanizing agent and the auxiliary vulcanizing agent into the extruder through a lateral feeding port in the middle front part of the extruder; and 6, applying pressure and conducting extrusion granulation.

Description

technical field [0001] The invention relates to the technical field of production and processing of thermoplastic elastomers, in particular to a high-performance TPV material and a continuous automatic production method thereof. Background technique [0002] With the needs of social development, high performance, refinement, and specialization of products have become an inevitable development trend. High efficiency, low energy, and green environmental protection have become social advocacy trends. Thermoplastic elastomer TPE is characterized by its excellent processing performance, high elastic performance, Economical applicability and low pollution have achieved vigorous development. [0003] TPV was developed later than simple blended TPO, but the development speed is very fast. At present, the global market capacity of TPV is about 700,000 tons, with an average annual growth rate of about 10%. TPV60% is used in the automotive field, and the main application scope include...
