Embodiment 1

[0020] Graphene oxide was prepared by the Hummers method. Cool 4L of 98% concentrated sulfuric acid to 0°C, add 20g of graphene, 10g of sodium nitrate and 6g of potassium permanganate, stir magnetically in a water bath at 0°C for 5 hours, heat up to 35°C, and react 30min, add 1L of deionized water, rapidly raise the temperature to 98°C, keep for 15min, stop heating, use 40°C deionized water to make up to 10L, add 1L of 30% hydrogen peroxide and 7L of 5% hydrochloric acid for pickling, magnetically stir for 5min, centrifuge and wash (7000r Remove the supernatant after centrifuging at 10 min at 10 min, stir for 1 min, add deionized water and centrifuge at 7000 r / min for 10 min, repeat this 3 times or more) until the pH is close to neutral to obtain graphite oxide, ultrasonic 2 h, make it fully peeled off, A graphene oxide suspension was prepared.

[0021] The hollow glass microspheres were leached in a 3.0 mg / ml graphene oxide suspension for 5 minutes, and then dried at 120° C. ...

Abstract

This case involves an anti-corrosion rubber that can isolate ultrasonic waves, including: 40-45wt% of fluororubber, 2-3wt% of vulcanizing agent, 2-3wt% of glass fiber, 5-8wt% of tungsten carbide powder, and 15-wt% of modified hollow glass beads 20wt%, mica powder 10-15wt%, vinyl silicone resin 10-15wt%, antioxidant 2-3wt% and plasticizer 2-3wt%; the anti-corrosion rubber capable of isolating ultrasonic waves not only has good anti-corrosion, It has excellent wear resistance and sealing performance, and has excellent ultrasonic absorption performance. It is suitable for lining, outer coating and sealing ring materials with ultrasonic functional devices.

Description

technical field [0001] This case involves the field of polymer materials, especially a kind of anti-corrosion rubber that can isolate ultrasonic waves. Background technique [0002] With the development of science and technology and the improvement of people's living standards, the use of ultrasound is becoming more and more common. No matter in laboratories, hospitals, factories and mines, or in kitchens and cleaning rooms, ultrasound is playing an important role. While ultrasound brings convenience to people, it also causes certain ultrasound pollution. [0003] Low-dose ultrasound is a potential carcinogenic and teratogenic factor, and different frequencies and different sound intensities have certain harm to different individuals. Because ultrasonic waves have a strong penetrating ability to solids and liquids, when the energy is large, it can make the material particles vibrate at high frequency, and part of the energy can also be converted into heat energy to increase...
