The invention relates to a dynamic thermoplastic vulcanizate material TPV with superior comprehensive performance, which is characterized by comprising the following raw materials by weight percentage: 15 to 30 percent of polypropylene, 30 to 50 percent of ethylene propylene terpolymer, 5 to 20 percent of ethylene-octene copolymer, 1 to 10 percent of styrene elastomer, 10 to 20 percent of plasticizer, 1 to 5 percent of polyethylene wax, 0.5 to 2 percent of vulcanizing agent, 0.5 to 2 percent of accelerating agent, 0.1 to 0.5 percent of antioxidant and 0.1 to 0.5 percent of lubricant. The preparation method comprises: weighing the raw materials according to the weight percentage; placing all the raw materials into a high-speed mixer and mixing the raw materials for 2 to 5 minutes; discharging the raw materials; and placing the uniformly mixed raw materials into a screw compressor for extrusion and granulation, wherein the rotating speed of the screw compressor is between 180 and 600 revolutions per minute, and the temperature is between 160 and 200 DEG C. The invention has the characteristics that the prepared thermoplastic elastomer material has high elasticity, overcomes the defect of poor elasticity of the prior TPV, and can be used in situations with high elasticity requirement and oil resistance.
Description
Technical field
The present invention relates to a kind of dynamic vulcanization thermoplastic elastomer material and preparation method of excellent combination property, this material can make have oil resistant and the production unit that elasticity is had relatively high expectations, instrument, fields such as instrument belong to the elastomer material technical field.
Background technology
Dynamic vulcanization thermoplastic elastomer (TPV) is that micron-level crosslinked rubber particles is dispersed in the polyolefin resin, and promptly rubber phase is a disperse phase, and the polyene hydrocarbon phase is the matrix material of external phase.At present, all good TPV of multiple performance have appearred both at home and abroad, and range of application expansion gradually, but owing to the crosslinked back of TPV elasticity descends to some extent, so snappiness TPV is fewer.
