Chemical recycling of glass fiber reinforced epoxy resin cured with amine using nitric acid

摘要: Abstract An approach to chemical recycling of amine cured epoxy resin using nitric acid solution has been proposed [Dang W, Kubouchi M, Yamamoto S, Sembokuya H, Tsuda K. Polymer 2002;43:2953–8. [1] ]. 1,8-p-Menthanediamine bisphenol F type (BPF/MDA) was decomposed in solution, and then the product repolymerized with original resin. In this paper, applicability glass fiber reinforced diamino diphenyl methane (DDM) investigated. It concluded that applicable BPF/DDM resin, potentially all Flexural strength recycled higher than virgin until content neutralized extract, which available from degradation not more 30 wt% The reinforcement could be separated recovered. existence did affect decomposition matrix.
