Abstract

The invention discloses flame-retardant and aging-resistant epoxy resin glass fiber reinforced plastic for the shell of a four-wheel electric vehicle. The flame-retardant and aging-resistant epoxy resin glass fiber reinforced plastic comprises, by weight, 70-85 parts of epoxy resin, 4-9 parts of polysiloxane, 4-9 parts lignin, 3-9 parts of curing agent, 2-4 parts of diluent, 10-20 parts of glass fibers, 1-9 parts of carbon fibers, 2-9 parts of graphene oxide, 1-3 parts of molybdenum disulfide, 2-7 parts of carbon nanotube, 3-9 parts of modified expandable graphite, 2-3.2 parts of samarium oxide, 1-5 parts of nano zinc oxide, 2-9 parts of nano titanium dioxide, 2-8 parts of dioctyl phthalate, 2-9 parts of triglycidyl isocyanurate, 2-3.8 parts of silane coupling agent KH-560, 2-9 parts of sepiolite and 2-11 parts of ammonium polyphosphate. The flame-retardant and aging-resistant epoxy resin glass fiber reinforced plastic is good in heat resistance and excellent in flame retardance and aging resistance.

Description

technical field [0001] The invention relates to the technical field of glass fiber reinforced plastics, in particular to a flame-retardant and aging-resistant epoxy resin glass fiber reinforced plastics for the shell of a four-wheel electric vehicle. Background technique [0002] FRP is fiber-reinforced plastic, which can be divided into polyester FRP, epoxy FRP and phenolic FRP according to the type of resin used. Epoxy FRP belongs to thermosetting FRP. It is based on epoxy resin and has the advantages of high mechanical strength, small shrinkage rate and stable manufacturing size. It has been widely used in the manufacture of machine parts and automobile and ship shells. However, the existing epoxy resin fiberglass is not very good in heat resistance and flame retardancy. When it is used in the shell of a four-wheel electric vehicle, it has the defects of poor heat resistance and flame retardancy, which shortens its service life. Contents of the invention [0003] Based...
