Abstract

The invention provides a preparation method of a wave absorbing member. The method comprises the following steps: mixing silicon rubber and a wave absorbing agent according to different weight ratios so as to prepare a plurality of wave absorbing slurries; and making the wave absorbing slurries into wave absorbing members through a tape casting technology. The invention further provides a wave absorbing member prepared through the method mentioned above. The provided preparation method can solve the problems that in related technologies the manufacturing technology of wave absorbing members is too complicated and continuous production cannot be achieved. The provided preparation method can achieve continuous production of wave absorbing members, and shortens the unit time for producing a wave absorbing member.

Description

technical field [0001] The invention relates to the field of device preparation, and in particular, to a method for preparing a wave absorbing member. Background technique [0002] At present, the miniaturization and high integration of electronic components will generate a lot of electromagnetic interference and make the living environment unhealthy. Therefore, the method of suppressing electromagnetic noise will generate a large market. The absorber can effectively suppress electromagnetic noise. For example, the absorber can be used to reduce the reflection of radar waves, reduce the interference of radar signals to airborne equipment, and suppress the interference of low-frequency signals to communication equipment. Therefore, microwave absorbing components have broad application prospects in military and civilian fields, and the general trend of the development of microwave absorbing components is thinner thickness, lighter weight, wider absorption frequency band, and s...
