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 glass fibers were leached in a 1.0 mg / ml graphene oxide suspension for 5 minutes, and then dried at 120° C. to obtain gra...

Abstract

This case involves a special sound-absorbing and anti-corrosion rubber for ultrasonic devices, including: 40-45wt% fluorine rubber, 2-3wt% vulcanizing agent, 10-12wt% modified glass fiber, 5-8wt% tungsten carbide powder, and 5-8wt% hollow glass microspheres 10wt%, mica powder 10-15wt%, vinyl silicone resin 10-15wt%, anti-aging agent 2-3wt% and plasticizer 2-3wt%; the special sound-absorbing and anti-corrosion rubber for ultrasonic devices of the present invention not only has good corrosion resistance, Wear-resistant and sealing, with excellent ultrasonic absorption performance, suitable for lining board, outer cladding, sealing ring material with ultrasonic function device.

Description

technical field [0001] This case involves the field of polymer materials, especially a sound-absorbing and anti-corrosion rubber for ultrasonic devices. 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 increas...
