Abstract

The invention provides a preparation method for a carbon wave-absorbing material. The carbon wave-absorbing material is composed of a carbon matrix material, a heat conduction carbon fiber, butyl acrylate and a 819 photo-initiator, the carbon matrix material is prepared from a reaction of activated carbon sponge, mesoporous carbon, a heat conduction carbon fiber, a nano carbon material and ferrite, the heat conduction carbon fiber is prepared by reacting a carbon fiber, copper acetate, Sr-10 emulsifiers, thiourea, water, ethanol, glucose and ammonia water, and the ferrite is prepared by reacting iron oxalate, cobalt oxalate, nickel oxalate, nano copper powder, acrylic acid, methoxy polyethylene glycol 550 monomethacrylate, and the 819 photo-initiator. The carbon wave-absorbing material prepared by the method of the invention has excellent wave-absorbing properties.

Description

technical field [0001] The invention relates to the technical field of functional materials, in particular to a method for preparing a carbon wave-absorbing material. Background technique [0002] With the development of the national economy and the improvement of people's quality of life, people have gradually begun to pay attention to the effective treatment materials or methods for the electromagnetic radiation problems encountered in the living environment. However, at present, my country's electromagnetic wave absorbing materials have the defects of narrow absorbing frequency and deviation of absorbing performance. In recent years, with the continuous improvement of people's quality of life requirements, people pay special attention to materials, household appliances or equipment that are produced in the process of life and affect people's health. However, due to the electromagnetic radiation problems of many existing household appliances, Therefore, there is an urgent...
