All the fluorocarbon coating applications
With all the fluorine carbon monomers and polymer application, the application field of fluorocarbon coatings more and more widely, besides the traditional coating surface finishing areas outside, still used for other more special important fields, such as large Bridges and high building anticorrosive, navy ships antifouling, chemical leather waterproof, prevent oil and surface active agent, etc, all visible fluorocarbon coating has been deeply into every aspect of the national economy, the application study of great significance.
2. 1 bridge building antisepsis
For large Bridges and high-rise buildings anticorrosive antifouling, although the traditional coating can also use, but because of short service life, weather resistance is poor, usually just a little year should be replaced once, not only to waste a lot of manpower material resources, but also on the people's life and property safety constitute a hidden danger. And all the fluorocarbon coating with its strong weathering resistance and corrosion resistance, used in large engineering Bridges and high building anticorrosive domain, its utility to (15 ~ 20) years, the effect lasting and beautiful. LiuYaLi etc with containing fluorine resin and hydroxyl isocyanate preparation got all the fluorine polyurethane coating, used in high-rise buildings, the plane, spacecraft, sea-crossing bridge, offshore oil drilling platform and the automobile field, use life can reach (10 to 20) years. WangYongQi [9] all the preparation of fluorocarbon coating, and studied the anticorrosion coating in the engineering application, the coating applied to acid rain in chongqing area of the more serious the jialing river bridge, 1993 still intact; Used in dalian binhai close to the seaside professional bridge, 1995 years is still intact, shows all the fluorocarbon coating good vitality.
2. 2 ships anticorrosive antifouling
Long-term sailing on sea naval ships, the bottom of the sea except by corrosion, but also by the sea creature's attached to the normal sailing ships have brought much inconvenience. The traditional coating for toxic baits, not only to the environment pollution caused great, and with the release of toxic material, its anticorrosion antifouling performance, gradually reduced. All the fluorocarbon coating of low surface can non-toxic antifouling coatings, application YuHaiJun ships antifouling not only lasting effect, and is free from pollution to the environment and harmless action, have important military significance.
TianJun etc [10] all the fluorine carbon low surface to the preparation of the antifouling coatings and antifouling mechanism. Contains all the long chains of fluoroalkyl, given all the fluorocarbon emulsion coatings low surface energy and low adhesion, so as to achieve the purpose of prevention. D. l. Schmidt [11] with polyethylene (2-isopropyl)-2-(oxazoline) make the activity fluoroalkyl polymer effectively crosslinking, and found the Marine life to this kind of fluoropolymer coatings adhesion strength is much lower than the average of the antifouling coatings (such as PTFE). TianJun, such as ZhouZhaoFu [12] with ptfe, poly two methyl silane, epoxy resin, paraffin wax oil, polyamide mixed solvents and other made harmless Marine antifouling coatings, room temperature curing antirust paint with good adhesion, antifouling sex strong, coating the ship bottom can effectively prevent the fouling attached sea creatures, and the specialties of biological function.
