Example Embodiment
[0044] Example 1
[0045] The basalt fiber and glass fiber mixed reinforced resin provided in this embodiment is prepared according to the following steps.
[0046] First, graphene oxide is added to the aqueous solution at a material-to-liquid ratio of 15 mg / mL, and then a coupling agent with a mass fraction of 3% in the aqueous solution is added. After mechanical stirring for 1 to 2 hours, ultrasonic dispersion is performed for 1.5 to 3 hours to obtain a fiber treatment solution. Treat the mixed fiber with the fiber treatment liquid for 50 minutes, and dry it under vacuum for 40 minutes to obtain the reinforced material. Among them, in terms of parts by weight, the mixed fiber includes 50 parts of basalt fiber and 25 parts of glass fiber.
[0047] Secondly, place the reinforcing material in the plasma generator, and use CF 4 It is a reaction gas, the reaction pressure is 15Pa, the reaction power is 150W, and the reaction time is 10min to obtain the modified reinforced material.
