Abstract
The invention discloses a thermoplasticelastomer applicable to an automobile charging system as well as a preparation method and application thereof. The thermoplasticelastomer is prepared from thefollowing ingredients in percentage by mass: 10 to 40 percent of SEBS, 5 to 25 percent of white oil, 5 to 25 percent of polypropylene, 10 to 30 percent of modified polyphenylether, 15 to 30 percent ofphosphorus-nitrogenous flame retardants, 0.2 to 1.0 percent of first antioxidants and 0.2 to 1.0 percent of first lubricating agents; the modified polyphenylether is prepared from polyphenylether, polypropylene, SEBS, white oil, second antioxidants and second lubricating agents through mixing according to the mass ratio of 1:(0.5 to 3):(0.5 to 3):(0.2 to 2):(0.01 to 0.05):(0.01 to 0.05). The preparation method comprises the steps of preparing modified polyphenylether and oil-filled SEBS, and then mixing the ingredients for preparation. The invention also provides application of the thermoplasticelastomer to a new energy automobile charging system. The thermoplastic elastomer has the effect that the comprehensive performance in each aspect is excellent.
Description
technical field [0001] The invention belongs to the technical field of polymer materials, relates to a material for a charging system of a new energy vehicle, and in particular relates to a thermoplastic elastomer suitable for a charging system of a vehicle and a preparation method and application thereof. Background technique [0002] SEBS is obtained by hydrogenation of thermoplastic elastomer SBS (styrene-butadiene-styrene block copolymer). After hydrogenation, the structure of SBS becomes polystyrene (S)-polyethylene (E)-polybutyleneAlkene (B)-polystyrene (S) block copolymer, so it is called SEBS for short. The carbon-carbon double bond in the molecular structure of SEBS is hydrogenated and saturated, so it has excellent properties such as weather resistance, aging resistance, heat resistance, and compression deformation resistance. The operating temperature of SEBS can reach 130 °C. What is especially valuable is that it has excellent ozone resistance, oxidation resis...
