Abstract
With the development of modern technology, electromagnetic shielding technology is becoming more and more widely used in various fields. Especially in special diving research, the application of electromagnetic shielding materials can not only protect the safety of scientific researchers, but also improve the accuracy and reliability of experimental data. This article will introduce the electromagnetic shielding technology of SBR (Styrene Butadiene Rubber) diving composite fabric in detail, including its working principle, product parameters, and application scenarios, and will also quote famous foreign literature for in-depth discussion. Afterwards, the specific parameters are displayed in the form of a table to provide readers with clear and clear information.
1. Introduction
Electromagnetic shielding refers to a technique that reduces electromagnetic interference by using conductive or magnetic materials to block or absorb electromagnetic waves. In special diving environments, electromagnetic shielding is particularly important because the underwater environment is complex and changeable, and the propagation and reflection characteristics of electromagnetic waves are different from those of land. In order to ensure the normal operation of scientific research equipment and the accuracy of data, it is crucial to choose the right electromagnetic shielding material. SBR diving composite fabrics are excellent in this regard as a high performance material.
2. Overview of SBR Diving Composite Fabrics
SBR (Styrene Butadiene Rubber), or styrene butadiene rubber, is a common synthetic rubber material. It has good elasticity and wear resistance and is widely used in tires, soles and other products. However, in recent years, researchers have found that after SBR is combined with other materials, it can maintain its original performance while giving it new functions, such as electromagnetic shielding performance. This composite material has great potential in special diving research.
2.1 Composite material structure
SBR diving composite fabrics are usually composed of three layers:
- Exterior layer: High-strength nylon or polyester fibers that provide mechanical strength and wear resistance.
- Intermediate layer: SBR is mixed with conductive fillers (such as carbon fibers, metal powders, etc.) to form an electromagnetic shielding layer.
- Inner layer: Soft skin-friendly material to improve wear comfort.
2.2 Preparation process
The preparation process of SBR diving composite fabric mainly includes the following steps:
- Raw Material Preparation: Select the appropriate SBR matrix and conductive filler.
- Mixing: Mix SBR with conductive filler to ensure uniform distribution.
- Modeling: The mixture is molded into the desired shape by hot pressing or injection molding.
- Composite: Combine the molded material with the outer and inner layer materials to form the final product.
3. Principle of electromagnetic shielding
The basic principle of electromagnetic shielding is to block or absorb electromagnetic waves through conductive or magnetic materials. Specifically, when electromagnetic waves encounter conductive materials, induced currents will be generated on the surface of the material, which will offset the incident electromagnetic waves, thereby achieving a shielding effect. For SBR diving composite fabrics, the conductive filler plays a key role.
3.1 Function of conductive fillers
Commonly used conductive fillers include carbon fiber, graphene, metal powder, etc. These fillers not only enhance the conductivity of the material, but also improve its mechanical properties. Studies have shown that the addition of carbon fiber and graphene can significantly improve the electromagnetic shielding efficiency of SBR composites (Smith et al., 2018). In addition, metal powders (such as copper powder and silver powder) can also effectively improve the shielding effect, but the cost is higher.
3.2 Shielding performance evaluation
Shielding performance (SE) is an important indicator for measuring the performance of electromagnetic shielding materials, usually expressed in decibels (dB). According to international standard ISO/IEC 17025, shielding performance can be calculated by the following formula:
[ SE = 10 log{10} left( frac{P{text{in}}}{P_{text{out}}} right) ]
Where ( P{text{in}} ) is the incident power and ( P{text{out}} ) is the transmitted power. Generally speaking, the higher the shielding effect, the better the shielding effect of the material.

5. Application scenarios
SBR diving composite fabrics are widely used in special diving research, mainly reflected in the following aspects:
5.1 Deep sea exploration
The deep-sea environment is extremely harsh and the electromagnetic interference is serious. The high shielding performance of SBR composite fabrics can effectively protect the detection equipment and ensure the stability and accuracy of data transmission. For example, in marine geological exploration, electromagnetic wave imaging technology requires an accurate electromagnetic environment, and SBR composite fabrics can provide reliable shielding protection for the equipment (Johnson & Lee, 2019).
5.2 Underwater Communication
Underwater communication equipment is susceptible to external electromagnetic interference, resulting in signal distortion or interruption. SBR composite fabric can effectively shield external electromagnetic waves and ensure communication quality. In particular, in military and rescue missions, stable communication links are crucial (Brown et al., 2020).
5.3 Biological monitoring
The underwater biological monitoring system requires long-term continuous operation. Electromagnetic shielding can prevent external interference and improve the accuracy of monitoring data. For example, in coral reef ecosystem research, SBR composite fabrics can provide a good shielding environment for sensors to ensure the authenticity and reliability of data (Davis & Miller, 2021).
