Polyurethane coating coating with crosslinking agent
2017-3-30 10:51:03
Polyurethane coating coating with crosslinking agent,Connelly, such as using fluoride - alkyl vinyl ether copolymer alternately. Fluoride aliphatic polyester and total fluoride hydroxy functional (meth) acrylate resin paint preparation for the paint of wind-power blades.
Maier, such as using isophorone diisocyanate (IPDI) and a polyol containing perfluorinated chain of the polyurethane modified fluoride coating was prepared, the coating temperature crosslinking, excellent weatherability, at the same time also has the oil. Waterproof and dustproof performance.
DiZhiGang to weather such as aliphatic polyester and hydroxyl fluoride resin as the main raw material, reaction with IPDI, synthesized a kind of high weather resistance wear elastic polyurethane crosslinker (EPU).
With traditional isocyanate trimer compared to commercially available elastic polyurethane crosslinker, use EPU crosslinking agent for crosslinked coating in weather. Abrasion resistance. Mechanical properties. Hydrolytic stability and composite material has obvious advantages in such aspects as substrate adhesion, wind-power blades can be used to defend.
Dong Xiang etc four fluorine fluorine carbon resin as film forming material, adding functional and hydrophobic agent of hydrophobic materials, match with HDI trimer as crosslinking system, coatings with low surface energy and high water contact Angle (143.2 °). The performance test results show that the coating from the cleaning effect is good, prevent adhesion effect is remarkable, has good hydrophobicity and anti-icing, wind-power blades can be applied to prevent ice, etc.
Using the FEVE fluoro resin Du Jingyi wait. More hydroxyl polyester and homemade ice resistance resin coating formulation system, the preparation has good elasticity. Resistance and long-term freezing resistance of coatings, the performance meet or exceed the wind blade coating technical indicators.
Based on the new film. And polished. Flooding and artificial aging treatment after freezing resistance coating for research, discovered that the water contact Angle for the film. The cold water experiment. Freezing rain experiment with ice force can meet the technical index of the fan blade coating freezing resistance, shows that the coating system have long-term freezing resistance.
Chinese name: Diethyl toluene diamine(DETDA)
Diethyltoluenediamine Uses:
The product is identical to Ethancure 100 and Lonza DETDA 80, DETDA is very effective polyurethane elastomer chain extender; also be used as polyurethane and epoxy resin curing agent, epoxy resin of an antioxidant, industrial oils and lubricants . In addition, also as intermediates in organic synthesis.Especially for the RIM (reaction injection molding), is important in the field of spray polyurea chain extender species. Also can be used for casting polyurethane elastomer (CPU) and a curing agent, epoxy curing agent, epoxy resin of antioxidants, lubricants and industrial oils other antioxidants.
Lots of research and production practice experience shows that fluorine resin has excellent weatherability and ice prevention performance, very suitable for use in wind power blade coating. However, pure fluorine resin coating flexibility as well as with other materials of poor adhesion, and resin production cost is very high, not suitable for separate. Large area is used.
Therefore, with the current widespread use of polyurethane or acrylic resin compound with use, or for fluorinated polyurethane and acrylic resin modified, in order to get a more excellent comprehensive performance of wind power blade coating, is a very worthy of development research direction.
Wang cong wind turbine blades were summarized such as ice. Types of ice and freezing process such as the status and progress, to all sorts of anti freezing and deicing strategy are analyzed.
Tian Penghui etc. This paper expounds the blade ice affect the performance of wind turbine, starting from the physical phenomena of ice, focuses on analyzing the advantages and disadvantages of various blade ice prevention technology is put forward a few leaves several research and development direction of the technology of ice.
In the material surface coating sacrifice sexual coating. Thin ice coating and super hydrophobic coating, etc., to form a coating with freeze resistance, become in recent years the research focus in the field of material surface resistance to freezing.
Currently use electric heating. Microwave. Mechanical. Air flow. Ultrasound and spraying chemical reagents such as active clear ice technology widely used, effect is good, but there are time consuming. Problems such as energy consumption and environmental pollution, and freezes on wind power blade coating resistant coating is both simple and convenient and environmental protection, wind-power blades become one of the important research direction of the technology of ice.
