1. Introduction The anti-corrosion curing agent for epoxy powder is a chemical additive used in epoxy powder coatings. It reacts with epoxy resin to form a cross-linked network, thereby improving adhesion, hardness, and corrosion resistance of the coating. In industrial applications, this material is widely employed for anti-corrosion protection of critical infrastructure such as ships, bridges, tanks, and pipelines. researching efficient, environmentally friendly, and cost-effective formulations of epoxy powder curing agents is of great significance for advancing related industries.

2. Raw Material Selection

1. Base Resin: Epoxy resin (e.g., bisphenol A type) serves as the primary component, determining the comprehensive properties of the coating. It offers excellent mechanical performance and chemical resistance.
2. Curing Agent: Compounds like multifunctional amines or anhydrides promote cross-linking. Amine-based curing agents with higher reactivity provide faster curing and better cross-link density.
3. Diluent: Solvents such as acetone, toluene, or ethyl acetate reduce viscosity for easier mixing and application. Low-volatility solvents with good solubility are preferred.
4. Fillers: Materials like quartz powder or talc enhance mechanical strength and wear resistance. Their type and dosage depend on specific requirements.
5. Additives: Coupling agents, dispersants, and leveling agents improve adhesion, flexibility, and impact resistance. Optimal selection and dosage vary by application.

3. Ratio Optimization

1. Base Resin Ratio: Higher epoxy resin content improves hardness and corrosion resistance but increases costs. Balancing performance and cost is essential.
2. Curing Agent Ratio: Excess curing agent accelerates curing but may compromise workability, while insufficient amounts lead to under-curing. Experimental testing determines the optimal ratio.
3. Diluent Ratio: Excessive diluents thin the coating, reducing protection, while inadequate amounts increase viscosity. Trials establish the ideal balance.
4. Filler Ratio: Overloading fillers makes application difficult, while insufficient fillers weaken mechanical strength. Experimental adjustments are required.
5. Additive Ratio: Excess additives degrade performance, while shortages limit functional improvements. Testing ensures proper dosage.

4. Curing Process Exploration

1. Temperature Control: Curing temperature critically affects reaction rates and coating quality. Optimal temperature ranges are determined experimentally.
2. Time Control: Insufficient curing time results in weak coatings, while over-curing causes brittleness. Experiments identify ideal curing durations.
3. Environmental Conditions: Humidity and airflow impact coating performance. High humidity reduces adhesion, while strong winds disrupt application. Optimized conditions are verified through testing.

5. Results and Discussion Experimental studies revealed:

1. A 1:1 ratio of epoxy resin to multifunctional amine curing agent yielded optimal hardness, corrosion resistance, and longevity.
2. Adding diluents improved coatability, fillers enhanced durability, and additives balanced flexibility and impact resistance.
3. Curing at 60–70°C for 8–10 hours produced the best results. Stable humidity and minimal airflow during curing were crucial.

This study successfully developed an industrially viable formulation for epoxy powder anti-corrosion curing agents. The formula demonstrates high performance but may require adjustments for specific applications. Small-scale trials and fine-tuning are recommended for practical production.
