Embodiment 1
[0041] For the modification treatment of carbon black (CB), the inventor of the present application has studied the use of silane coupling agent to carry out modification treatment and the use of oxidant to carry out modification treatment. The protection of the present invention adopts oxidation modification CB / CFDSF / AG-80 The preparation method of oxygen resin composite material;
[0042] A preparation method for preparing oxidation-modified CB / CFDSF / AG-80 epoxy resin composite material, mainly comprising the following steps:
[0043] 1. Modification of carbon black (CB) with concentrated nitric acid
[0044] Use concentrated nitric acid to modify carbon black (CB). First, take 4g of carbon black and 50ml of concentrated nitric acid with a concentration of 65wt% and pour them into a beaker, heat to 100°C and stir for 2 hours, then dilute with distilled water and filter with suction , scrape off the filtered CB carefully, put it into a beaker and pour a large amount of disti...
