Embodiment 1

[0049] The method for preparing battery tray of the present invention, its specific steps are as follows

[0050] 1) The preparation of pre-product: in nitrogen atmosphere, take tetramethylcyclotetrasiloxane and styrene as raw material, take the isopropanol solution of chloroplatinic acid as catalyst (wherein tetramethylcyclotetrasiloxane, benzene The molar ratio of ethylene and isopropanol solution of chloroplatinic acid is 80:20:4); the catalyst and styrene are mixed to prepare the styrene catalyst solution, and the styrene catalyst solution is slowly added dropwise into tetramethylcyclotetrasiloxane. Control the styrene catalytic liquid to be added dropwise within 30 minutes, and then continue to react for 20 hours under the condition of nitrogen protection at 45°C, and then use activated carbon adsorption at 45°C to adsorb too much catalyst, and filter the obtained after 45 minutes of adsorption The filtrate is distilled under reduced pressure, the vacuum degree is contro...

Abstract

The invention discloses a preparation device for a battery tray based on a graphene toughened high-performance carbon fiber resin-based composite and a preparation method. The method comprises the steps that graphene and a low-viscosity reactive dispersant are subjected to ultrasonic dispersion to obtain graphene dispersion liquid, then the graphene dispersion liquid is directly sprayed uniformlyon the surface of the carbon fiber fabric to prepare a toughened resin of a certain concentration, graphene toughened carbon fibre preprepreg is prepared by continuous impregnation and drying, then the graphene toughened carbon fibre composite is prepared by layer laying, mould pressing and curing. Compared with the prior art, the weight of the battery tray is obviously reduced, and more stabilityis achieved.

Description

technical field [0001] The invention relates to a preparation device and a preparation method of a battery tray based on graphene-toughened high-performance carbon fiber resin-based composite material. Background technique [0002] Battery performance and vehicle lightweight determine the mileage of electric vehicles and directly affect the development and popularization of new energy vehicles. How to further reduce the weight of the battery module on the basis of ensuring the safety of the battery module has become a technical hotspot in material and structural design. The battery tray of the electric vehicle is used to fix and protect the battery. At present, metal materials are mainly used to ensure the firmness and stability of the battery during the fast driving of the electric vehicle. Although the metal tray can meet the requirements in terms of rigidity and strength, it is relatively heavy. [0003] Carbon fiber resin matrix composite material is a kind of composit...
