Embodiment 1- Embodiment 7

[0024] A preparation method of an oil-resistant composite material for an automobile drive motor, comprising the following steps:

[0025] S1. Preparation of adhesive:

[0026] Add 100 parts of acrylic resin to the solvent 80-100 parts of acetone, methyl acetate and ethyl acetate, after mixing evenly, add 30-40 parts of special epoxy resin and 20-30 parts of polyurethane resin to the mixture, mix well, The adhesive was obtained, and the specific preparation parameters of the adhesive were shown in Table 1;

[0027] S2. Preparation of composite materials:

[0028] On the soft composite material production equipment, the polyethylene naphthalate film is passed through the glue tank containing the adhesive-resistant adhesive prepared in step S1, the speed of the equipment is set to 3-6m / min, and then the The baking tunnel with a length of 5m is baked. The temperature of the first stage of baking is 80-100 ° C, the temperature of the second stage is 90-110 ° C, and the temperatu...

Abstract

The invention discloses an oil-resistant composite material for an automobile driving motor as well as a preparation method and application of the oil-resistant composite material. The oil-resistant composite material comprises two aromatic polyamide fiber paper layers, an adhesive layer and a polyethylene naphthalate film layer, the polyethylene naphthalate film layer is bonded between the two aromatic polyamide fiber paper layers through the adhesive layer; the adhesive is prepared by mixing 100 parts by mass of acrylic resin, 30-40 parts by mass of special epoxy resin, 20-30 parts by mass of polyurethane resin and 80-100 parts by mass of a solvent A; the composite material is used for slot insulation, slot wedge and phase insulation of the internal oil cooling type electric vehicle driving motor; the flexible composite material overcomes the defects of foaming and layering of the existing flexible composite material in ATF oil, and has excellent mechanical property, electrical property and oil resistance, so that the performance of a driving motor product is more stable and reliable in the service life cycle.

Description

technical field [0001] The invention belongs to the field of soft material preparation, in particular to an oil-resistant composite material for an automobile driving motor and a preparation method and application thereof. Background technique [0002] In recent years, in order to solve the increasingly serious problems of resource crisis and environmental pollution, the Chinese government has vigorously promoted the research and innovation of new energy electric vehicles, issued relevant development plans, and provided a good policy environment to support, encourage and guide the development of electric vehicles. The rapid development of new energy vehicles has provided a good opportunity for the development of the new energy vehicle motor industry. As one of its core components, the drive motor and its control system have broad prospects for development. [0003] At present, the slot insulation, slot wedge and phase insulation of the internal oil-cooled electric vehicle dr...
