Embodiment 1

[0031] S1. Put 1g of the mixture of multi-walled carbon nanotubes and graphene nanosheets in a 2-liter beaker according to the mass ratio of 2:1, add ultrapure water to obtain a dispersion with a concentration of 1g / L, and then place the flask on In a cooling tank at 5°C, the mixture was circulated through the ultrasonic transducer using a peristaltic pump. Then the ozone produced by the oxygen concentrator and ozone generator is continuously passed into the dispersion liquid, and this process lasts for 16 hours, so that the multi-walled carbon nanotubes and graphene nanosheets are oxidized;

[0032] S2, 0.06g glacial acetic acid (mass percentage concentration 80%) is added in the dispersion liquid, the pH value of the dispersion liquid is adjusted to 5.8, then 2g cationic polyacrylamide (CPAM) is joined in the dispersion liquid, then in 15 Ultrasonic treatment at ℃ for 4 hours to functionalize the multi-walled carbon nanotubes and graphene nanosheets, so that the oxidized mul...

Abstract

The invention belongs to the field of basalt fiber composite materials, and relates to a preparation method of a basalt fiber composite material. The method comprises the following steps of: S1, dispersing multi-walled carbon nanotubes and graphene nanosheets in ultrapure water, and introducing ozone to oxidize the multi-walled carbon nanotubes and the graphene nanosheets to finally obtain a dispersion liquid; S2, adding glacial acetic acid into the dispersion liquid obtained in S1, and then adding cationic polyacrylamide; S3, cleaning the surfaces of basalt fibers for later use; S4, performing electrophoretic deposition on the positively charged multi-walled carbon nanotubes and graphene nanosheets treated by the cationic polyacrylamide in the step S2 on the basalt fibers in the step S3 to obtain pretreated basalt fibers; and S5, coating the pretreated basalt fibers obtained in the step S4 with a mixed solution of resin and a curing agent, and then carrying out mold pressing to obtain the basalt fiber composite material. The preparation method disclosed by the invention is simple and easy to implement; and the prepared basalt fiber composite material is convenient for damage monitoring, and defects caused to the material are effectively avoided.

Description

technical field [0001] The invention belongs to the field of basalt fiber composite materials, in particular to a preparation method of basalt fiber composite materials. Background technique [0002] A promising material for a variety of applications is basalt, which is solidified from volcanic lava. Basalt fiber is a technologically advanced fiber developed by the Moscow Institute of Glass and Plastics from 1953 to 1954 due to its high strength, high modulus, high and low temperature resistance, chemical resistance, UV resistance, low moisture absorption , Sound insulation, heat insulation, excellent environmental resistance and other performance characteristics, so in recent years it has been used in various fields such as civil engineering, transportation, aerospace and so on. Wuyan fiber is made through a similar process to glass fiber, but with lower energy consumption and no additives, making it less expensive than glass or carbon fiber. Basalt fiber is continuously ...
