What is epoxy-based fireproof coating?
Epoxy-based fireproof coating is a thick fireproof coating made of epoxy resin as film-forming material, flame retardant, foaming agent, carbon source, additives, etc. It can form a dense foam carbon layer at high temperature, effectively preventing heat transfer, and is widely used in steel structures, tunnels, oil platforms, storage tanks and other fields.
Key equipment coniguration of epoxy-based fireproof coating production line
| Work section | Main equipment | Technical parameters |
| Raw material processing | Automatic metering system | Accuracy ±0.5%, supports weighing of flame retardants (APP/aluminum hydroxide), epoxy resin, curing agent and other raw material |
| Premixing | High speed dispersing kettle | Speed 0-1500rpm, with jacket temperature control (room temperature~80℃) |
| Grinding and dispersing | Basket sand mill | Zirconium bead particle size 0.3-0.8mm, fineness≤20μm (key processing section for fireproof fillers) |
| Reaction modulation | Reactor | SS304/316, with anchor+dispersing disc double stirring, vacuum degassing (-0.095MPa) |
| Filtration and packaging | Automatic filling system | Accuracy +1%, explosion-proof design (suitable for solvent-based coatings), production capacity 200-500barrels/hour |
Technical advantages of epoxy-based fireproof coating production line
1. Intelligent dispersion technology
Three-stage dispersion process (premixing + high-speed shearing + nano-grinding) ensures that the fineness of the flame retardant is ≤20μm adn the fire resistance is improved by 30%.
2. Precision temperature control system
Dual-mode temperature control (thermal oil + coil cooling), temperature accuracy ±1℃, to avoid premature curing of the resin.
3. High-efficiency flame retardant performance
The directional arrangement process makes the fire resistance limit reach 2.5 hours, far exceeding the industry standard.
4. Environmentally friendly and safe design
VOCs recovery rate ≥905, optional explosion-proof configuration and nitrogen protection system.
5. Flexible production
Switch between water-based/solvent-based coating production in 5 minutes, supporting flexible adjustment of multiple formulas.
