Epoxy Emulsion

The environment-friendly epoxy emulsion was synthesized by MAA, BA, St reacting as grafting monomer, while silane coupling agents played a role as functional monomer. Experimental results were characterized by Nano-particle size analyzer, EIS, UV-VIS spectrophotometer, FTIR and TGA. The results of Nano-particle size analyzer showed the average particle size lower than 300nm and emulsion had lowest water absorption when ω(KH560+KH550) was 7%. The results of EIS and UV-VIS spectrum showed the cured firm had the best corrosion resistance and weather resistance while n(KH560):n(KH550)=2:1. The results of FTIR showed the silane coupling agents had successfully grafted in the skeletal structure of epoxy molecules. The results of TGA showed the thermal stability were better than unmodified.

In this investigation, metallocene polyethylene (m-PE) was melt blended with poly(ethylene terephthalate) (PET) with an effort to achieve improved mechanical properties using a novel eccentric rotor extruder (ERE) without the addition of any compatibilizers. The phase morphology, rheological properties, crystallization behavior, and mechanical properties of the fabricated blends were carefully studied to explore the effect of the elongational flow field on the dispersion and mixing of PET in the m-PE matrix and the interface of the two immiscible polymers. For comparison, a conventional twin-screw extruder (TSE) was used to prepare the same blends as references using the same processing condition. It shows that the elongational flow field in ERE is much more effective to disperse the immiscible PET in the m-PE matrix with a smaller particle size and a narrower particle size distribution, compared to the shear flow field in TSE. A compatibilizer, ethylene-co-methyl acrylate-co-glycidyl methacrylate (E-MA-GMA), was added to the m-PE/PET blends during the processing using TSE and ERE. It was observed that the improvement of the tensile property by adding the compatibilizer is marginal for the m-PE/PET blends processed using ERE, which indirectly proves the high effectiveness of the elongational flow field on the enhancement of the dispersion and mixing of PET in the m-PE matrix and the interface interaction.
