1. Introduction
As the demand for deep-sea exploration and marine resource development continues to increase, the safety and reliability of deep-sea equipment are particularly important. Among them, waterproof sealing technology is one of the key factors in ensuring the safety of divers. Traditional waterproof materials often find it difficult to maintain good sealing in high-pressure environments, while SBR composite fabrics show significant advantages in deep-sinking environments due to their excellent physical and chemical properties. This article will conduct in-depth discussion on the waterproof sealing technology of SBR composite fabrics and its application in deep-sinking environments.
2. Overview of SBR Composite Fabrics
2.1 Material Characteristics
SBR (styrene butadiene rubber) is a synthetic rubber widely used in the industrial field, with the following characteristics:
- Weather Resistance: Can maintain stability under extreme temperature and humidity conditions.
- Abrasion resistance: High surface hardness, not easy to wear, and prolong service life.
- Tear resistance: It has high tear resistance and is suitable for complex environments.
- Elastic recovery ability: Can quickly restore the original state and reduce deformation accumulation.
| Features | Description |
|---|---|
| Weather resistance | Stay stable under extreme temperature and humidity conditions |
| Abrasion resistance | High surface hardness and not easy to wear |
| Tear resistance | High tear resistance |
| Elastic Resilience | Quickly restore to its original state |
2.2 Structural Design
SBR composite fabrics are usually composed of multi-layer structures, each layer having a specific function to achieve an optimal waterproof sealing effect. Common structures include:
- External protective layer: woven from high-strength fibers to provide mechanical protection.
- Intermediate Waterproof Layer: Use SBR rubber coating to ensure waterproof performance.
- Inner Comfort Layer: Choose soft and breathable materials to improve wear comfort.
| Hydraft | Materials | Function |
|---|---|---|
| External protective layer | High-strength fiber | Providing mechanical protection |
| Intermediate waterproof layer | SBR Rubber Coating | Ensure waterproofing |
| Inner Comfort Layer | Soft and breathable material | Improving comfort in wearing |
3. Principles of waterproof sealing technology
The waterproof sealing technology of SBR composite fabrics mainly relies on its unique molecular structure and processing technology. There is a strong hydrogen bonding between the molecular chains of SBR rubber, so that the material can fit tightly when under pressure to prevent moisture from penetration. In addition, advanced coating technology and heat treatment processes further enhance the waterproofing properties of the material.
According to literature [1], the waterproofing mechanism of SBR composite fabrics can be summarized into the following aspects:
- Intermolecular force: hydrogen bonding between the molecular chains of SBR rubber.
- Coating Technology: A physical barrier is formed by coating a dense SBR rubber film.
- Heat treatment process: Rearrange the rubber molecules at high temperatures to enhance sealing.

In order to better understand the performance of SBR composite fabrics, the following are its main technical parameters and performance indicators:
| parameter name | Unit | Test Method | Typical |
|---|---|---|---|
| Tension Strength | MPa | GB/T 528-2009 | ≥15 |
| Elongation of Break | % | GB/T 528-2009 | ≥500 |
| Tear Strength | kN/m | GB/T 529-2008 | ≥40 |
| Hydraulic pressure resistance | MPa | GB/T 12706-2008 | ≥0.5 |

5. Application in deep-dive environment
In deep-sinking environments, the waterproof sealing technology of SBR composite fabrics has been widely used. Especially in the fields of deep-sea adventure, marine scientific research and subsea engineering, its excellent performance is highly favored.
5.1 Deep Sea Adventure
Deep sea adventure requires equipment to be highly waterproof and compressive. SBR composite fabrics can withstand huge water pressure to ensure the safety of divers. For example, during the Mariana Trench expedition, the researchers used all the diving suits used by SBR composite fabrics, which successfully withstand the pressure of thousands of meters of water depths.
5.2 Marine Science and Technology
Marine scientific research equipment requires long-term soaking in water, so it has extremely high requirements for waterproofing performance. The excellent waterproof performance of SBR composite fabric makes it an ideal choice for scientific research equipment. Literature [2] points out that in Antarctic scientific research, waterproof clothing made of SBR composite fabric effectively protects researchers from the influence of severe cold and moisture.
5.3 Undersea Engineering
Seawater engineering involves a large number of underwater operations, such as pipeline laying, bridge construction, etc. SBR composite fabrics not only prevent moisture from infiltration, but also resist corrosion of seawater and extend the service life of the equipment. Research shows that pipelines wrapped with SBR composite fabrics show excellent corrosion resistance in the submarine pipeline laying project in the Beihai Oilfield.
6. Practical application case analysis
In order to more intuitively demonstrate the application effect of SBR composite fabrics, the following are several typical application cases:
6.1 Case 1: Mariana Trench Expedition
- Project Background: Mariana Trench is a deep trench in the world, with a large depth of more than 11,000 meters.
- Solution: A diving suit made of SBR composite fabric can withstand water pressure up to 110MPa.
- Effect Evaluation: During the entire adventure, there was no leakage in the diving suit, ensuring the safety of the divers.
6.2 Case 2: Antarctic Scientific Expo
- Project Background: The Antarctic climate is harsh, with extremely low temperatures and wind and snow.
- Solution: Waterproof clothing made of SBR composite fabric, with good thermal insulation and waterproof performance.
- Effect Evaluation: The scientific expedition team members worked in an extremely cold environment for several months, and the waterproof clothing was always kept dry, effectively protecting the team members’ physical health.
6.3 Case 3: Paving of subsea pipelines in Beihai Oilfield
- Project Background: Beihai Oilfield is located in a cold water area. The seawater contains a lot of salt and has extremely high requirements for the anti-corrosion performance of the pipeline.
- Solution: Pipes wrapped with SBR composite fabrics have excellent corrosion resistance after special treatment.
- Effect Evaluation: The pipeline was soaked in seawater for many years and no signs of corrosion were found, ensuring the safety and stability of oil transportation.
7. Comparison with other materials
To highlight the advantages of SBR composite fabrics, we compare them with other common materials:
| Material Name | Weather resistance | Abrasion resistance | Tear resistance | Elastic Resilience | Comprehensive Evaluation |
