To study the flame-retardant efficiency, the curing agents were incor-porated into the epoxy resins, and the fire safety and the degradation mechanisms and especially the relationship of the structure–property were investigated.

With the acceleration of industrialization, the application of various materials has become increasingly widespread. Among them, epoxy curing agents, as a critical component in epoxy resin floor coatings, composite materials, electronic encapsulation materials, and other products, directly impact the quality and safety of these applications. stringent fire safety standards for epoxy curing agents are essential to ensure the safe use of these materials.

I. Basic Concept and Function of Epoxy Curing Agents

Epoxy curing agents are substances that promote chemical cross-linking reactions in epoxy resins. By reacting with hydroxyl groups in the resin, they form stable three-dimensional network structures, thereby enhancing mechanical strength, chemical resistance, thermal stability, and electrical insulation properties. In epoxy resin floor coatings, curing agents play a crucial role in determining the hardness, wear resistance, and adhesion of the coating.

II. Importance of Fire Safety Standards

1. Ensuring Personnel Safety: Epoxy curing agents may release toxic gases such as formaldehyde and benzene under high temperatures, posing health risks to prolonged exposure. Fire safety standards require curing agents to avoid releasing hazardous substances during use, ensuring the health and safety of workers.

2. Preventing Fire Accidents: Epoxy curing agents can burn rapidly in fires, generating significant heat and smoke, which exacerbates fire spread. Fire safety standards mandate low calorific values and good flame-retardant properties to reduce fire risks.

3. Extending Product Lifespan: Fire safety standards ensure epoxy curing agents maintain thermal stability and chemical resistance in harsh environments, prolonging the lifespan of products.

III. Specific Requirements of Fire Safety Standards

1. Low Smoke and Halogen-Free Content: Epoxy curing agents must comply with international standards for low smoke and halogen-free emissions to minimize smoke and harmful gases during fires.

2. High Flame-Retardant Rating: Curing agents should meet high flame-retardant standards, such as UL94 V-0 or V-1, to prevent ignition and slow fire spread.

3. Thermal Decomposition Resistance: Curing agents must exhibit excellent thermal stability to avoid harmful gas emissions during high-temperature conditions.

4. Chemical Corrosion Resistance: Curing agents should resist chemical erosion to maintain stability and durability.

5. Environmental Requirements: Production processes must minimize pollution, avoid toxic substances, and prioritize recyclability to reduce environmental impact.

IV. Implementation and Regulation

1. Strict Production Standards: Manufacturers must adhere to national and industry standards to guarantee product quality.

2. Strengthened Market Supervision: Regulatory authorities should enforce compliance with standards and penalize non-compliant epoxy curing agents to maintain market order.

3. Public Awareness: Education campaigns should raise awareness of fire safety performance in epoxy curing agents, encouraging consumers to choose compliant materials.

Fire safety standards for epoxy curing agents are vital for material safety and protecting lives and property. Continuous improvement in product quality and standards is essential to meet social demands and drive healthy industry development.
