Overview of Automatic Fire Suppression Materials

1. Definition and Working Principle

Automatic fire suppression materials refer to materials that can automatically respond and play a fire suppression role when a fire occurs. Their working principle is mainly based on the detection of physical or chemical signals related to fire, such as heat, smoke, and flames. Once a fire signal is detected, the automatic fire suppression materials will release fire suppression substances through chemical reactions or physical changes to suppress the development of the fire. Common working methods include releasing fire suppression gases, forming thermal insulation layers, and blocking the supply of oxygen.

2. Types and Characteristics

• Fire Suppression Sprays: Usually based on wet chemical or foam materials, they are commonly used in enclosed spaces such as kitchens, laboratories, and industrial facilities. When a fire occurs, the spray will quickly release fire suppression agents to form a barrier to isolate oxygen, effectively extinguishing small to medium-sized fires. Its advantage is high fire suppression efficiency, which can quickly control the fire.
• Fire-resistant Fabrics: These include fabrics used for making protective clothing and building materials. In a high-temperature environment, these fabrics will be automatically activated to release flame-retardant chemicals or form a fire-resistant barrier. Fire-resistant fabrics have the characteristics of light weight and good flexibility, which can effectively prevent the spread of fire and are often used to protect workers’ safety, vehicle interiors, and building insulation.
• Thermoplastic and Intumescent Coatings: Intumescent coatings will expand when heated to form a thick thermal insulation layer to protect the underlying surface from fire damage. This type of coating is often used in parts such as steel beams, doors, and structural supports of commercial buildings to provide long-term fire protection.
• Fire Suppression Gels: They can be applied to the surface to form a fireproof barrier and are often used for wildfire suppression, which can effectively slow down the spread of fire among vegetation. It has good adaptability to both natural and artificial surfaces and can prevent the spread of fire.

 

Basic Principles and Classification of Adhesives

1. The Bonding Principle of Adhesives

The bonding effect of adhesives is mainly based on the intermolecular forces, including van der Waals forces, hydrogen bonds, and chemical bonds. When the adhesive is applied to the surfaces of two objects, the adhesive molecules will interact with the molecules on the surfaces of the objects to form a tight bond. As the adhesive cures, the intermolecular forces are enhanced, thus achieving a firm bond between the two objects.

2. Common Types of Adhesives

• Epoxy Resin Adhesives: They have high strength, high chemical resistance, and good heat resistance, and are commonly used for bonding materials such as metals, ceramics, and plastics.
• Polyurethane Adhesives: They have good flexibility and wear resistance and are suitable for bonding various elastic materials and porous materials, such as rubber, wood, and fabrics.
• Silicone Adhesives: They have excellent weather resistance, high-temperature resistance, and electrical insulation properties and are often used in fields such as building sealing and fixing electronic components.
• Acrylate Adhesives: They have a fast curing speed and high bonding strength and are widely used for the rapid bonding of materials such as plastics, metals, and glass.

 

Application Research of Automatic Fire Suppression Materials in Adhesives

1. Modes of Combination and Technical Difficulties

The ways of combining automatic fire suppression materials with adhesives mainly include physical mixing and chemical modification. Physical mixing is to uniformly disperse the particles of the fire suppression materials in the adhesive. This method is simple and easy to implement, but there may be problems such as uneven dispersion and poor stability. Chemical modification is to introduce the active components of the fire suppression materials into the molecular structure of the adhesive through chemical reactions to achieve a more stable combination, but the technical difficulty is relatively high, and the reaction conditions need to be precisely controlled. In practical applications, how to ensure the uniform dispersion of automatic fire suppression materials in the adhesive, not affect the curing process of the adhesive, and maintain long-term stability are the main technical difficulties faced.

2. Impact on the Performance of Adhesives

• Improvement of Fireproof Performance: After adding automatic fire suppression materials, the fireproof performance of the adhesive is significantly improved. When a fire occurs, the fire suppression materials can quickly respond to inhibit the spread of the flame and extend the fire resistance time of the material. For example, the adhesive containing intumescent coating materials will expand to form a thermal insulation layer when heated, effectively protecting the bonded part from fire damage.
• Changes in Bonding Performance: The addition of automatic fire suppression materials may have a certain impact on the bonding performance of the adhesive. On the one hand, the particles of some fire suppression materials may interfere with the interaction between the adhesive molecules and the surface of the bonded object, resulting in a decrease in bonding strength. On the other hand, the change in the molecular structure of the adhesive after chemical modification may change its bonding characteristics. However, through the reasonable selection of automatic fire suppression materials and the optimization of the formulation, it is possible to minimize the negative impact on the bonding performance while improving the fireproof performance. Research shows that with a carefully formulated recipe, the adhesive can still maintain high bonding strength while obtaining good fireproof performance to meet the needs of practical applications.

3. Analysis of Application Cases

• Industrial Field: In chemical production equipment, adhesives added with fire suppression gels are used for the sealing and bonding of pipelines and equipment. When a fire occurs, the adhesive can quickly form a fireproof barrier to prevent the fire from spreading to the inside of the equipment, effectively protecting the equipment and production safety.
• Construction Field: In the building exterior wall insulation system, adhesives containing fire-resistant fabric fibers are used to bond the insulation panels. This adhesive not only has good bonding performance but also can provide additional fire protection when a fire occurs, delaying the spread of the fire and buying time for personnel evacuation and fire rescue.
• Electronic Field: In the assembly of electronic devices, adhesives added with components of fire suppression sprays are used to fix electronic components. This adhesive can not only ensure the firm bonding of the components but also quickly extinguish the fire when a short circuit in the device causes a fire, protecting the expensive electronic devices.
