Abstract

The invention discloses a preparation method for a composite material applied to the shell of an igniter of a motor vehicle. The preparation method comprises the following steps: stirring metallocenepolypropylene, an acrylonitrile-butadiene-styrene copolymer, epoxy resin, calcium stearate, diphenyl monooctyl phosphate, microcrystalline paraffin and octyl 9,10-epoxystearate to obtain a premix a; stirring calcined kaolin, multi-walled carbon nanotubes, bentonite, zeolite powder, fumed silica, an antibacterial compound, a coloring agent, molybdenum disulfide, methyl silicone oil and an anti-aging agent to obtain a premix b; and uniformly mixing the premix a with the premix b under stirring, and successively carrying out melt mixing, extrusion granulation, drying and injection molding to obtain the composite material used for the shell of the igniter of the motor vehicle. The antibacterial compound is prepared by uniformly mixing silver nitrate with propylene glycol, adding chitosan and iron powder, carrying out grinding, adding the obtained mixture into an aqueous acetic acid solution, adjusting a pH value to no less than 7, adding ethylene oxide, carrying out stirring, and then carrying out freeze-drying.

Description

technical field [0001] The invention relates to the technical field of motor vehicle igniters, in particular to a method for preparing a composite material for a motor vehicle igniter shell. Background technique [0002] Existing automobile and motorcycle igniters utilize the ignition coil to generate high voltage at the moment of ignition to penetrate the spark plug gap and discharge ignition, igniting the mixed gas in the engine cylinder to make the engine move. [0003] The existing engine igniter has the following disadvantages: long-term use is easy to accumulate dirt on the surface of the igniter shell and breed bacteria, which needs to be solved urgently. Contents of the invention [0004] Based on the technical problems existing in the background technology, the present invention proposes a method for preparing a composite material for a motor vehicle igniter housing. The obtained composite material has excellent mechanical properties, excellent aging resistance an...
