1. Definition and composition: cross-border combination of nano technology and ceramic materials
Organic silicon nano ceramic coating is a multifunctional composite material prepared by combining nano ceramic powder as the core functional phase, with organic silicon resin matrix and special additives. Its core innovation lies in controlling the size of ceramic particles within the range of 1-100 nanometers through nano technology, forming a microstructure with refined grains and increased grain boundaries, while introducing the flexibility and film-forming properties of organic silicon to achieve complementary advantages between ceramic materials and organic systems. The typical formula includes active metal micro powder, nano ceramic powder (such as alumina, zirconium oxide), and a full range of rare earth powder as fillers, with inorganic phosphate or modified organic silicon resin as the film-forming material, supplemented by dispersants, leveling agents and other additives, and a stable dispersion system is formed through a chelating wetting process.
2. Performance breakthrough: six core advantages beyond traditional coatings
The temperature resistance limit is greatly improved: the cured coating can withstand extreme temperatures of 380℃ to 3000℃. For example, 1023 ultra-high temperature anti-oxidation coating is used in the hot end parts of aircraft engines, which can extend the life of the parts by more than 3 times.
A leap in hardness and wear resistance: nano-ceramic fillers make the coating hardness reach 9H, which is 2-3 times that of traditional coatings. In the automobile wheel protection test, the coating thickness loss is only 0.02mm after 100,000 frictions.
A revolutionary breakthrough in anti-corrosion performance: by forming a dense chemically inert protective film, the anti-corrosion ability is 3-10 times better than zinc. In offshore drilling platform applications, the salt spray test life is increased from 500 hours to 5000 hours.
The environmental performance is significantly optimized: using a water-based solvent system, VOC emissions are close to zero, and the drying time is shortened by 50% compared with latex paint, which meets the EU REACH environmental protection standards.
Functional integrated design: By adding photocatalytic materials such as nano titanium dioxide, self-cleaning, antibacterial, and UV protection are achieved. In building curtain wall applications, the dirt adhesion rate is reduced by 80%.
Enhanced construction adaptability: A variety of processes such as spraying, infiltration, and coating can be used to form a uniform coating on complex curved substrates, and the adhesion reaches level 0 (the highest level) in the GB/T 9286 standard.
3. Application areas: Full scene coverage from industrial heavy corrosion protection to civilian consumer products
In the industrial field, this coating has become a standard protection solution for heat transmission pipelines, high-temperature furnaces, and offshore equipment. The application of a single project can reduce maintenance costs by more than 60%. In the civilian market, nano-ceramic coatings for non-stick pans occupy 35% of the high-end kitchenware market due to their characteristics of not containing perfluorooctanoic acid (PFOA); in the field of electronic consumer products, after the mobile phone middle frame and laptop computer shell are coated with this coating, the wear resistance test pass rate has increased from 70% to 99%. In the aerospace field, nano ZrO₂ thermal barrier coating reduces the surface temperature of turbine blades by 200°C and increases the engine thermal efficiency by 8%, becoming one of the core technologies of the domestically produced large aircraft C919.
