The durability and mechanical properties of epoxy ester coatings and films has been improved by blending with rigid aromatic polyurea (PU). The interaction of PU and epoxy ester was enhanced by coupling the polymers with polymethylhydrosiloxane. The reactions between various entities are analyzed by Fourier transform infrared spectroscopy and the change in physical and mechanical properties are studied by a dynamic mechanical analyzer. The corrosion resistance of the hybrid coatings was measured by direct current polarization method, direct current polarization (DCP). The addition of polymethylhydrosiloxane enhances the corrosion properties in the hybrid coatings. The surface morphology was analyzed by scanning electron microscopy. The glass transition temperature of the films increases with increasing PU concentration and a wide glass rubber transition range for hybrid coatings was achieved which confirms the higher impact strength of the hybrid coatings and films. © 2012 Wiley Periodicals, Inc.

环氧粉末的固化时间及热特性是三层结构聚乙烯防腐层( 3PE)涂敷时工艺设置的重要参数,准确的固化时间数据是确保各层之间形成最佳结合的关键。本研究选取了 6种典型环氧粉末样品,研究了固化后涂层不同存放环境及后处理方式对环氧粉末涂层固化时间及固化后热特性的影响。研究发现固化时间测试时涂层用水淬冷后,放置周期及存放环境对固化涂层热特性测试结果会产生一定的影响,甚至可能会得出错误的结果,从而影响对粉末涂料固化时间的准确判断。通过对各样品不同放置周期、不同干燥处理方式的对比测试,发现随着涂层在潮湿环境下放置时间的增加,玻璃化温度的变化值( ΔTg)在逐渐增大,但将涂层在一定温度下进行加热除湿处理后,又可以得到与淬冷后立即进行测试时相当的结果。由此可见,固化涂层样品长时间放置过程中水分子由表面扩散至涂层内部引起涂层塑化,进而导致涂层玻璃化转变温度降低,可能是影响固化时间及热特性测试的关键因素。  相似文献

The effects of different contents of ultra-fine glass fiber on mechanical and anticorrosion properties of epoxy coatings have been investigated. The FTIR and SEM have been used to analyze the surface nature and microstructure of the coatings. Electrochemical impedance spectroscopy (EIS) and a salt spray test have also been used to characterize the contents of ultra-fine glass fibers on the impedance of the coatings. When 10%, 20%, 30% of ultra-fine glass fibers are added to the coatings, their hardness and adhesion increases by 67%, 67%, 200% and 21.6%, 39%, 40%, respectively, compared with the properties of the pure coating. But the anticorrosion properties of the coatings containing high ultra-fine glass fiber content decreased with respect to the pure coatings properties.  相似文献

The thermomechanical stability of a number of organosilane surface treatments for glass fibers was evaluated for use in a fiber reinforced epoxy resin. All of the silane coatings were found to improve the tensile strength of E-glass filaments, particularly at large gauge lengths. A phenylamino silane and an amino silane were particularly effective in this regard. The fiber/matrix interface was evaluated as a function of temperature and after exposure to boiling water using a single-fiber composite test. All silane coatings transmitted a higher interfacial shear stress than obtained in composites with no coatings, and in all cases the shear stress transmission was considerably higher than would be expected from the yield properties of the resin. Measurements of the glass transition temperature of the epoxy resin, as well as Fourier-Transform Infra-Red analysis, indicated modification of resin properties in a zone around the glass fibers. Each of the silane coatings provided more stable thermomechanical properties than those obtained with uncoated glass, at least until the silanes were irreversibly degraded by boiling water. A phenylamino silane provided the most thermally stable properties. Finally, unidirectional E-glass fiber reinforced laminae were fabricated and the measured values of longitudinal strength were compared favorably to theoretical predictions.  相似文献
