Title The Study on the Synthetic Technology of High Resistant Epoxy Resin
Abstract Epoxy resin is a kind of thermosetting resin who has been widely used. In order to expand the application of epoxy resin, it is meaningful that improving heat resistance of epoxy resin. With the continuous development of high and new technology, and puts forward higher and higher requirements for epoxy resins, and thus constantly promotes the research and development of high performance epoxy resin.
Tri-(4-hydroxyphenyl) methane ether the article introduced is a heat resistant epoxy resin. It has excellent tenacity and process ability, and it is widely used as high performance composite and encapsulation materials. In order to gain heat-resistant epoxy resin matrix. Three factors such as the addition manner of the alkali, reaction temperature and catalyst usage was studied for gaining the best parameter of the synthesis of tri-(4-hydroxyphenyl) methane triglycidyl ether, poly(amic acid)s was chose for the hardener. The product had been proved to have good mechanical properties and bonding strength. The chemical structure of tri(4-hydroxyphenyl) methane triglycidyl ether was characterized by Fourier-transform infrared (FTIR) spectrometer and 1H NMR spectrometer.
The results showed that the optimum technological condition is the material ratio of epoxy chloropropane to tri(4-hydroxyphenyl) methane is 1:30, the catalyst is NaOH in saturated solution, reaction temperature is 60℃, under this condition, the epoxy value is 0.6285, the product yield is 85.65%.
