Abstract

The invention discloses a preparation method of polypropene plastic for a high-toughness instrument panel. The preparation method comprises the following steps: stirring random copolymerization polypropylene, nitrile silicone rubber, a methyl methacrylate-butadiene-styrene terpolymer, 1,1-bis-(t-butylperoxy)cyclohexane, a calcium oxide complex, lignin fibers, nanometer bentonite, heavy calcium carbonate, coal gangue powder, mica powder, an antioxidant ODA, an antioxidant BLE, pine tar, oxidized polyethlene wax and coumarone resin and then putting in a double-screw extruder for extrusion and granulation to obtain the polypropene plastic for the high-toughness instrument panel. The calcium oxide complex is prepared by adopting the following processes: uniformly mixing calcium oxide and ethylene oxide, grinding under the protection of nitrogen, standing, adding an ethanol solution, adjusting the temperature, stirring, allowing standing still, filtering, drying and crushing to obtain the calcium oxide complex. The polypropene plastic for the high-toughness instrument panel, disclosed by the invention, is good in mechanical property, good in toughness, high in impact strength and good in heat and aging resistance.

Description

Technical field [0001] The invention relates to the technical field of instrument panels, in particular to a preparation method of polypropylene plastic for high-toughness instrument panels. Background technique [0002] In order to ensure that the supported instruments can work normally under high-speed driving and vibration conditions, the instrument panel must have sufficient rigidity, and in order to reduce the impact of external forces on the driver and co-pilot in the event of an accident, the instrument panel is also required to have good toughness . [0003] The traditional instrument panel is made of polypropylene material. Although the rigidity is good, the toughness cannot meet the demand, and it needs to be solved urgently. Summary of the invention [0004] Based on the technical problems existing in the background technology, the present invention proposes a method for preparing high-toughness polypropylene plastic for instrument panels. The obtained polypropylene plas...
