Abstract

The invention discloses a highly-flame-retardant polypropylene composite material for new energy automobiles, and a preparation method thereof. The highly-flame-retardant polypropylene composite material for new energy automobiles comprises polypropylene resin, polyacrylamide microspheres, ethyl stearate, paraffin, dodecanoic acid, 1,3:2,4-di-p-methylbenzylidenesorbitol, dimethyl malonate, iron sodium tartrate, melamine, magnesium salt whiskers, lithium porcelain stones, calcium stearate, diethylene glycol monoacrylate, nano-aluminum powder, carbon fibers, hydroxyethyl acrylate, acrylic acid,nano-copper powder, microcrystalline graphite and methyl diphenylene diisocyanate. The preparation method comprises the following steps: preparing a mixture I and a mixture II, feeding the mixture I into the main feed port of a double screw extruder, feeding the mixture II from the side port of the double screw extruder, performing mixing, and carrying out extruding granulation to obtain the highly-flame-retardant polypropylene composite material for new energy automobiles. The sole material of the present invention has excellent aging resistance.

Description

【Technical field】 [0001] The invention belongs to the technical field of preparation of polypropylene composite materials, and in particular relates to a high flame-retardant polypropylene composite material for new energy vehicles and a preparation method thereof. 【Background technique】 [0002] New energy vehicles refer to the use of unconventional vehicle fuels as power sources (or the use of conventional vehicle fuels, the use of new vehicle power devices), integrated vehicle power control and advanced technology in driving, the formation of advanced technical principles, with Automobiles with new technology and new structure. New energy vehicles include: hybrid electric vehicles (HEV), pure electric vehicles (BEV), fuel cell vehicles (FCEV), hydrogen engine vehicles, gas vehicles, alcohol ether vehicles, etc. [0003] When the methyl groups are arranged on the same side of the molecular main chain, it is called isotactic polypropylene. If the methyl groups are arranged...
