Problems solved by technology

Most of its heat-conducting powder and wave-absorbing powder are inorganic metal materials. It is difficult to fully mix inorganic metal materials and polymer materials evenly through the traditional rubber mixing preparation process, and this patent does not consider the problem of uniform mixing and solution
If it is not fully mixed, not only the performance consistency of the obtained product cannot meet the requirements, but also the stress and density distribution in the product is uneven, the inorganic metal powder is easy to settle and separate, and the product is also prone to bending deformation.
Secondly, the product cannot have good flame retardancy

Abstract

The invention relates to rubber with excellent flame retardant and wave absorbing performance. The rubber with the excellent flame retardant and wave absorbing performance comprises the following components: a rubber matrix, an electromagnetic wave absorbent, dimethyl silicone oil, talcum powder, a flame retardant, a carbon fiber material, a stripping agent, a silane coupling agent and a vulcanizing agent. The rubber with the excellent flame retardant and wave absorbing performance disclosed by the invention has reasonable components. The electromagnetic wave absorbent can absorb most of electromagnetic waves radiating on the surface of the electromagnetic wave absorbent by virtue of polarization mechanisms such as hysteresis loss, eddy current loss and residual loss, and consumes the electromagnetic energy by converting the electromagnetic energy into heat energy or other forms of energy by virtue of electric or magnetic loss of the material. The electromagnetic wave absorbent is combined with the rubber to prepare the composite functional material with low reflectivity, scattering and transmittance. When applied to an electronic device, the product of the rubber with the excellent flame retardant and wave absorbing performance can absorb the additional electromagnetic waves, thereby reducing the influence of electromagnetic wave radiation for the device and human body.
