Publish Time: 2025-12-24
With the rapid development of new energy, power transmission, and intelligent buildings, cable systems and battery boxes, as core units for energy transmission and storage, have made fire safety a top priority in engineering design. Traditional fire protection measures such as fire-retardant tape, fire-retardant coatings, or metal conduits often suffer from cumbersome construction, poor adhesion, easy cracking, or insufficient thermal insulation performance. Flame-retardant thermal insulation protective materia, with its superior comprehensive performance and flexible construction methods, not only significantly improves on-site operation efficiency but also strengthens passive fire protection capabilities from the material's inherent level, constructing an efficient, reliable, and durable safety barrier for cables and battery boxes.1. Multi-process adaptability: Significantly shortens the construction cycleFlame-retardant thermal insulation protective materia supports multiple construction methods, including manual brushing, traditional air spraying, and high-pressure airless/air-assisted spraying, greatly improving adaptability to different scenarios. In confined cable trays or complex wiring areas, precise brush application can be used for coverage; in large battery boxes or rows of cable trunks, high-pressure spraying can achieve rapid and uniform film formation. High solids content means fewer coats per unit area, with a single coat achieving a film thickness of 300–500 micrometers, avoiding the need for multiple layers to dry. Combined with rapid curing characteristics, the overall construction cycle is shortened by more than 50% compared to traditional fire-retardant coatings, effectively alleviating construction schedule pressures, and is especially suitable for renovation projects or emergency protection needs.2. Seamless Continuous Coating: Eliminating Weak Points in Fire ProtectionTraditional fire-retardant tapes or spliced protective materials easily form heat conduction channels at the joints. In the event of a fire, flames and high-temperature smoke can spread rapidly along these gaps. This flame-retardant topcoat, after spraying, forms a completely seamless, dense, and continuous protective layer, tightly wrapping the cable sheath or battery box surface, without overlaps or gaps. This integrated encapsulation structure not only enhances the overall aesthetics but, more importantly, eliminates structural defects in the fire protection system. It ensures that under high-temperature flame impact, heat cannot rapidly penetrate through microscopic channels, effectively slowing the rate of internal temperature rise.3. Multi-functional Integration: One Coating, Multiple Effects, Enhancing Overall Safety LevelFlame-retardant thermal insulation protective material not only possesses excellent flame-retardant properties but also boasts high strength, scratch resistance, and corrosion resistance. The cured coating achieves a hardness of over 2H, resisting mechanical impacts during installation and friction damage during routine maintenance. It also exhibits good resistance to acids, alkalis, salt spray, and oil stains, making it suitable for harsh environments such as underground utility tunnels, coastal power plants, or industrial plants. For new energy battery boxes, this composite protection prevents external fire sources from igniting the box and suppresses flame jets and heat spread in the early stages of battery thermal runaway, buying valuable time for fire response.4. Thermal Insulation and Stability: Delaying Temperature Rise and Ensuring System IntegrityIn fire tests, cables coated with this flame-retardant and heat-insulating topcoat maintained circuit integrity for over 90 minutes under a 950°C flame, far exceeding the few minutes limit for unprotected cables. Its insulation mechanism stems from the coating's expansion and carbonization at high temperatures, forming a porous carbon layer with low thermal conductivity, effectively blocking heat transfer inwards. Similarly, when applied to the surface of battery boxes, it significantly reduces the thermal radiation impact of external fires on internal battery cells, delaying heat spread and improving overall package safety redundancy.5. Environmental Protection and Long-Term Reliability: Balancing Present and FutureThis two-component system contains no halogens, heavy metals, or other harmful substances. The curing process results in extremely low VOC emissions, meeting green building material standards. Furthermore, the coating exhibits strong adhesion to the substrate and excellent aging resistance, with a service life exceeding 10 years. It requires no frequent maintenance or recoating, reducing total life-cycle costs.Flame-retardant thermal insulation protective materials, with "efficient construction + inherent safety" as its core values, simplify complex fire protection engineering into a single intelligent coating. It's not just a technological upgrade, but a revolution in safety philosophy—shifting from passive response to proactive defense, and from localized protection to system integration. In today's world where cable and battery safety is increasingly crucial to public safety, this high-performance topcoat is becoming an "invisible armor" protecting energy infrastructure.
