Fireproofing technology and application of SBR diving composite fabric
Introduction
With the advancement of modern technology and the increase in demand in special environments, the safety and functionality of diving equipment have become particularly important. SBR (Styrene Butadiene Rubber) composite fabrics are a new material, due to their excellent physical properties and chemical stability, and perform well in various complex environments. This article will introduce the fire protection technology of SBR diving composite fabric in detail, and explore its safety and guarantee role in special diving scenarios.
1. Overview of SBR Composite Fabrics
1.1 Material Characteristics
SBR is a synthetic rubber, mainly composed of polymerization of styrene and butadiene. It has good wear resistance, tear resistance and aging resistance, and is widely used in tires, soles and other products that require high elasticity. In order to meet the needs of diving equipment, SBR composite fabric combines the advantages of a variety of materials to form a unique structure and performance.
| parameters | Description |
|---|---|
| Density | 0.9-1.2 g/cm³ |
| Tension Strength | ≥15 MPa |
| Elongation of Break | ≥400% |
| Abrasion resistance | 3 times higher than natural rubber |
| Tear resistance | ≥40 kN/m |
1.2 Composite structure
SBR composite fabrics are usually designed with multi-layer structures to improve their overall performance. Typical composite structures include:
- Exterior layer: High-strength fiber fabric that provides mechanical protection.
- Intermediate layer: SBR rubber layer, giving elasticity and waterproof functions.
- Inner layer: Anti-static coating to prevent charge accumulation and improve safety.
2. Principles of fire protection technology
2.1 Fire risk analysis
In special diving scenarios, such as deep-sea oil and gas exploration, underwater rescue, etc., fire risks cannot be ignored. These environments may contain flammable substances or high-temperature equipment, and the consequences will be unimaginable if a fire occurs. Therefore, the development toolA diving suit with fireproof function is crucial.
2.2 Fire prevention mechanism
The fireproof technology of SBR composite fabrics is mainly realized through the following methods:
-
Addition of flame retardant: Add an appropriate amount of flame retardant to SBR rubber, such as aluminum hydroxide, zinc borate, etc. These additives can release non-combustible gas during combustion and inhibit the spread of flame.
-
Self-extinguishing design: By special treatment of the fiber fabric, it can be extinguished quickly after contacting the fire source, avoiding continuous combustion.
-
Insulation layer setting: Set up an efficient insulation material, such as aerogel, inside the fabric, effectively blocks heat transfer and protects the wearer from high temperature damage.
| Flame retardant types | Additional amount (wt%) | Main Function |
|---|---|---|
| Aluminum hydroxide | 10-20 | Endrative decomposition, reduce temperature |
| Zinc borate | 5-10 | Form a protective film to isolate oxygen |
| Expanded Graphite | 3-8 | Fast expansion, covering the surface |
2.3 Experimental verification
A study published in the famous foreign document Journal of Applied Polymer Science (2018) shows that flame-retardant SBR composite fabrics perform excellently under simulated fire conditions, and the combustion time is shortened to 1/3 of ordinary materials , and there is no obvious melting phenomenon. In addition, an article in “Fire Safety Journal” (2020) also pointed out that the self-extinguishing performance of this type of fabric is significantly better than that of traditional diving suit materials.
3. Application in special diving scenarios
3.1 Deep-sea oil and gas exploration
Deep-sea oil and gas exploration is a high-risk operation involving a large number of flammable substances and high-pressure equipment. The fire-resistant properties of SBR composite fabrics can effectively prevent fire accidents caused by accidental leakage and ensure the safety of divers’ lives. At the same time, its excellent water resistance and compressive resistance also provide reliable guarantees for long-term operation.
3.2 Underwater rescue
Underwater rescue missionIt often faces complex environmental conditions, such as ruins, oil pollution, etc. In this case, SBR composite fabrics can not only resist external threats, but also maintain good flexibility, allowing rescuers to move quickly. According to a study by the International Journal of Safety and Emergency Management (2019), wetsuits made with such fabrics show higher efficiency and safety in actual rescue operations.
3.3 Scientific investigation
Polar scientific investigation is another important application scenario. In extreme cold environments, ordinary materials are prone to brittle cracking, while SBR composite fabrics can still maintain good protective effects due to their excellent low-temperature toughness. In addition, its fire resistance can also cope with possible emergencies and provide all-round protection for scientific expedition team members.
4. Summary and Outlook
The fireproof technology of SBR diving composite fabrics plays an important role in special diving scenarios, significantly improving operational safety and efficiency. In the future, with the continuous emergence of new materials and new technologies, we can expect more innovative results to be applied to this field. For example, the application of nanotechnology will further enhance the flame retardant performance of fabrics; the integration of intelligent sensors can realize real-time monitoring and early warning functions, providing divers with more comprehensive safety guarantees.
