Graphene reinforcing glass fiber for pantograph slide plate and preparation method of graphene reinforcing glass fiber

[0028] (1) Glass fiber unbundling: Rinse glass fibers with a radial size of 15-25 μm and a length greater than 1 mm with clean water for 4 times to remove soluble salt and alkali, and disperse the rinsed glass fibers in clean water. Disperse the glass fiber into a single bundle by ultrasonic dispersion, further filter dry, dry, and thermally expand and disperse to obtain unbundled glass fiber;

[0029] (2) Graphene metallization: Mix graphene powder with a radial size of less than 1 μm and a layer thickness of less than 10 nm with copper powder with a particle size of less than 10 μm at a mass ratio of 10:1, and force grinding in a ball mill to make the graphene interface and copper powder Full contact to form graphene-copper powder dispersion;

[0030] (3) Mosaic assembly: mix the unbundled glass fiber obtained in step (1) with the graphene-copper powder dispersion obtained in step (2) metallization at a mass ratio of 100:10, and send it into the air flow disperser, Under the a
