Description
Technical field
This invention relates to nano combined gel coat of a kind of weather resistant and preparation method thereof, and the nano combined gel coat of this weather resistant is mainly used in cooling tower glass fiber reinforced plastic surface.
Background technology
Cooling tower is equipment conventional in industrial circulating water, is usually used in Steel Plant, printing and dyeing mill, Medicine Factory, nuclear power plant, air-conditioning, freezer and the field such as chemical fibre, oil.Cooling tower tower body conventional is at present generally glass reinforced plastic, and for improving the material of glass reinforced plastic visual appearance and protective glass steel structural layer not by extraneous dielectric corrosion, glass fiber reinforced plastic surface of being everlasting applies one deck gel coat.Gel coat is the kind of a kind of special applications in unsaturated polyester resin, its main constituent is macromolecular material, therefore be often exposed to when it in various environment such as sunlight, wind and rain, high temperature, severe cold, As time goes on, its weathering resistance can decline, thus causes the phenomenon such as efflorescence, variable color.For improving gel coat weather resistance, one method uses the better unsaturated polyester resin of weather resistance, another kind method is carried out preferably to the filler in gel coat, because filler can improve the physical strength of gel coat, wear-resisting, water-fast and weather resistance (Cao Xin, the research of weather resistant fire retardant glue coating resin, fibre composite, 2005,1:10-11; Zhang Huijuan, each component of gel coat on the impact of gel coat aging resistance, East China University of Science, Engineering Master paper in 2011).
Nano-ZnO is a kind of polyfunctional new oxide, and it has surface effects, volume effect, quantum size effect and macroscopical tunnel effect and the feature such as high-clarity, polymolecularity that macro object do not have.In addition, nano-ZnO also has and covers ultraviolet performance preferably, and its UV-preventing rate is up to 98%.But when filler uses, also be there is following two problems in nano-ZnO at present:
1), nano-ZnO surface energy is high, easily reunites, bad with matrix resin consistency, for addressing this problem, normal coupling agent or the tensio-active agent of using carries out surface modification to nano-ZnO at present, but this method of modifying can use a large amount of organic solvent usually, as ethanol, toluene etc., their contaminate environment, poisonous to human body, also can increase and reclaim or destroy cost (Shi Zhen etc., the Research on Surface Modification of nano-ZnO, Shanghai coating, 2008,46 (5) 1-3; Wu Wenming, Pan Lei etc., the surface modification of nano-ZnO and the preparation of ZnO/UPR matrix material, thermosetting resin, 2009,24 (5): 44).
2) its addition in matrix resin of modified at present nanoparticle is little, otherwise opposite effect can be played to the performance of resin, as reduced mechanical property, increasing that dope viscosity causes can not shaping (Wu Wenming such as grade, Pan Lei etc., the surface modification of nano-ZnO and the preparation of ZnO/UPR matrix material, thermosetting resin, 2009,24 (5): 44; Wang Haifeng, Xu Yi etc., nanometer Al
