Fluorosilicone oil empowers extreme protection in both Marine and power grid fields to achieve dual breakthroughs

1. Industry pain point: Extreme environments give rise to the demand for upgrading protective materials
Marine biofouling and icing on power grid equipment have long been the "chronic problems" that restrict the safe operation of these two major fields. Data shows that China incurs economic losses of over 100 billion yuan each year due to corrosion and biological fouling of Marine equipment, while faults caused by ice accumulation on power grid equipment account for more than 40% of power outages due to extreme weather conditions. Traditional protection solutions either have environmental risks or face the problem of insufficient durability - organotin-based antifouling coatings have been banned, conventional silicone coatings have a lifespan of less than one year in the high salt spray environment of the ocean, and the power grid thermal ice-melting technology has extremely high energy consumption, accounting for 15% to 30% of the power generation of wind turbines. The search for materials that combine long-lasting protection with environmental protection features has become an urgent need in the industry.

2. Technological Innovation: Microcapsules and molecular modification solve dual challenges
Recently, a major breakthrough has been achieved in the multi-functional protection technology based on fluorosilicone oil. Through two innovative paths, namely "intelligent release of microcapsules" and "precise regulation of molecular structure", the pain points of Marine pollution prevention and anti-icing of power grids have been simultaneously addressed. In the field of Marine protection, the R&D team has molecular grafted fluorosilicone oil with quaternary ammonium salt antibacterial groups. By taking advantage of the low surface energy characteristics of fluorine segments and the contact bactericidal effect of the antibacterial groups, a synergistic anti-fouling mechanism has been formed. When the coating forms a film, the fluorosilicone segments automatically migrate to the surface, making it difficult for fouling organisms to attach. In terms of power grid protection, mesoporous alumina microcapsules are used to encapsulate fluorosilicone oil, and a "temperature-stress" dual-mode response release system is constructed. When the ambient temperature drops below 0℃ or the ice layer pressure is triggered, the microcapsules automatically rupture to release the silicone oil, forming a long-lasting anti-icing film on the surface of the equipment.


3. Performance verification: The protective effect has been significantly enhanced in extreme environments
A series of performance test data show that the new fluorosilicone oil protective material demonstrates excellent adaptability to extreme environments. The fluorosilicone anti-fouling coating for Marine use has been immersed in a simulated seawater environment for three years. The coating integrity rate still exceeds 95%, and the anti-adhesion rate against stubborn fouling organisms such as barnacles reaches 98%. At the same time, it has passed the Marine biological toxicity test and meets environmental protection standards. The anti-icing coating for power grids reduces the ice adhesion strength to below 50kPa, which is 60% lower than that of traditional silicone coatings. It maintains good flexibility in a low-temperature environment of -40℃ and shows no cracking or peeling after 1,000 cold and hot cycles. In addition, both coatings have excellent construction compatibility and can be adapted to the complex structures of offshore platforms and the curved surface spraying requirements of wind turbine blades, with uniform film thickness in a single coat.


4. Industrial value: Domestic technology breaks the reliance on imports
At present, this fluorosilicone oil protective material has been piloted and applied in the Zhoushan Cross-sea Bridge, offshore wind power projects and power grids in the northern high-cold regions. After the offshore platform pipelines in the Zhoushan sea area were protected by coating, there was no obvious biological attachment within six months, and the maintenance cycle was five times longer than that of traditional coatings. After a wind farm in the north adopted anti-icing coating, the ice thickness of the equipment in winter was reduced by 70%, and the energy consumption for ice melting was lowered by 65%. It is worth noting that the related technologies have formed completely independent intellectual property rights, breaking the long-term reliance on imports for high-performance Marine anti-fouling coatings. All raw materials used in the production of the materials are domestic industrialized products, and the cost is 30% lower than that of similar imported products. Industry experts point out that the large-scale application of this technology will promote the upgrading of protection in the Marine engineering and power industries, and help achieve energy conservation, consumption reduction and safe operation under the "dual carbon" goals.
