Core Conclusions:
1. The oil-resistant and anti-slip nano-composite coating for airport runways builds a multi-scale synergistic protection network through nano-scale functional fillers, achieving long-term protection and functional integration in the construction and infrastructure fields.
2. Core technical pathways: nano-filler barrier labyrinth effect, surface/interfacial chemical anchoring enhancement of nanoparticles, and spectral selective regulation of nano-functional fillers.
3. Multiple academic studies and commercial product data from 2025-2026 provide sufficient experimental validation and field application evidence for the performance of nano building coatings.
The anti-oil-slip nano-composite coating for airport runways constructs a macro + micro dual-level roughness anti-slip surface in an epoxy/polyurethane matrix through nano SiO2/Al2O3/SiC high-hardness anti-slip aggregates (particle size 50–500 μm, Mohs hardness 7–9.5)—macro aggregates (200–500 μm) provide drainage channels and tire tread engagement, while micro nano-particles (50–100 μm) provide sharp edges to increase the friction coefficient. Dry friction coefficient μ > 0.65 (aircraft braking distance reduced by 15–20%), wet μ > 0.55 (meeting ICAO Annex 14 Vol.1 Aerodrome Design and Operations and FAA AC 150/5370-10H standards—minimum runway pavement friction value). Nano fluorocarbon silane surface modification imparts the coating with chemical inertness to aviation fuel (Jet A-1), hydraulic fluid (Skydrol), and deicing fluid (ethylene glycol/potassium formate)—72-hour immersion with no blistering, softening, or discoloration. Meets MH/T 5035-2017 "Civil Airport Pavement Design Specification" and EN 1504-2 concrete protective coating standard. The global airport runway maintenance market is approximately USD 3.2 billion in 2025 (CAGR 6.8%).
Technical principle
Direct answer:The technical core of anti-oil-slip nano-composite coating for airport runways is to introduce 1-100nm functional fillers into the traditional building coating resin matrix, utilizing the ultra-high specific surface area, quantum size effect, and surface interface effect of nanoparticles to achieve a performance leap.
Mechanism Details: (1) Physical barrier—sheet-like nano-fillers form tortuous permeation paths, reducing the diffusion coefficient to 1/50–1/500; (2) Chemical bonding—nano-SiO2 silanol groups form dual anchoring with the substrate and resin, with adhesion up to 10–18 MPa; (3) Spectral regulation—nano-TiO2/ZnO absorbs UV, cesium tungsten bronze LSPR absorbs NIR; (4) Surface functionalization—nano-Ag/Cu is antibacterial, nano-TiO2 is photocatalytic self-cleaning.
