The influence of different rubber matrices on the absorption performance of rubber patch type absorbing materials

Brief introduction

Rubber patch type absorbing materials, as an efficient electromagnetic wave absorbing material, are widely used in wireless communication, radar, electromagnetic shielding and other fields. Its absorption performance is not only affected by the type and content of the absorbing agent, but also significantly constrained by the properties of the rubber matrix. As a leader in this field, Advanced Institute (Shenzhen) Technology Co., LtdResearch Platinum brand rubber patch type absorbing materialThe performance on different rubber substrates has attracted much attention. This article will explore in depth the influence of different rubber matrices on the absorption performance of Yanbo brand rubber patch type absorbing materials.

2、 Types and characteristics of rubber substrates

The type and properties of rubber matrix, as the carrier of absorbing materials, have a crucial impact on the absorbing performance. Common rubber substrates include silicone rubber, chloroprene rubber, natural rubber, nitrile rubber (NBR), etc., each of which has unique physical and chemical properties.

• Silicone rubber: It has excellent high temperature resistance, aging resistance, as well as good flexibility and sealing properties.
• Chloroprene rubber: It has excellent oil resistance, solvent resistance, and weather resistance, and is suitable for various harsh environments.
• Natural rubber: good elasticity, excellent processing performance, but relatively weak aging resistance.
• Nitrile rubber (NBR): It has outstanding oil and solvent resistance, as well as good mechanical strength and wear resistance.

3、 The influence of different rubber matrices on the absorption performance

1. Electromagnetic field mutual cancellation effect

Rubber patch type absorbing materialOne of the working principles is to weaken electromagnetic interference waves by mutual cancellation of electromagnetic fields. When the external electromagnetic field reaches the surface of the rubber patch, the conductive particles inside the material (such as metal particles or magnetic materials) will absorb electromagnetic wave energy and generate an electromagnetic field opposite to the external electromagnetic field, thereby achieving mutual cancellation of the internal and external electromagnetic fields. The dielectric constant and magnetic permeability of different rubber matrices vary, which can affect the response characteristics of conductive particles in electromagnetic fields, thereby affecting the mutual cancellation effect of electromagnetic fields.

• Silicone rubber: Due to its lower dielectric constant, it may allow conductive particles to move more freely in electromagnetic fields, which is beneficial for forming stronger internal electromagnetic fields and enhancing the mutual cancellation effect of electromagnetic fields.
• Chloroprene rubber: It has excellent weather resistance, but its dielectric properties may not be as good as silicone rubber in certain frequency bands, resulting in slightly inferior electromagnetic field cancellation effects.

2. Energy Conversion and Dissipation

Another important working principle of rubber patch type absorbing materials is to weaken electromagnetic interference waves through energy conversion and dissipation. During the process of absorbing electromagnetic wave energy by conductive particles, some of the energy is converted into thermal energy and dissipated. The thermal conductivity and stability of different rubber matrices vary, which can affect the efficiency of heat transfer and dissipation within the material.

• NBR rubber: Due to its excellent oil and solvent resistance, as well as high thermal stability, it may make the dissipation of heat inside the material more efficient, thereby improving its absorption performance.
• Natural rubber: Although it has good elasticity, its thermal stability is relatively weak, which may lead to heat accumulation in high temperature environments and affect the absorption effect.

3. Mechanical and processing properties

The mechanical and processing properties of rubber matrix will also indirectly affect itAbsorberThe absorption performance. Good mechanical properties help maintain the stability and durability of absorbing materials during use; And excellent processing performance makes it easy to adjust the shape and size of materials according to actual needs.

• Silicone rubber and chloroprene rubber: both have good flexibility and sealing properties, and are easy to process into various shapes of patches, suitable for applications in complex environments.
• NBR rubber: high mechanical strength and good wear resistance, especially suitable for occasions with high mechanical performance requirements.
