PREPARATION AND CHARACTERIZATION OF SIDE CHAIN EPOXY MODIFIED SILICONE OIL FOR PRECURSOR FIBER OF CARBON FIBER
Journal Title: Topics in Chemical & Material Engineering (TCME) - Year 2018, Vol 1, Issue 1
Abstract
In the carbon fiber production process, the oil agent is a very important part that affects the quality of the carbon fiber, and the epoxy group can improve the heat resistance of the silicone oil, so the epoxy modified silicone oil can be used as an integral part of the carbon fiber precursor oil agent. In this article, the preparation and characterization of side chain epoxy modified silicon oil for precursor fiber of carbon fiber will be reported. There were two major steps to prepare epoxy modified silicone oil. In the first step, low hydrogen silicone oils were synthesized by using octamethylcyclotetrasiloxane (D4) and 1,3,5,7-tetramethylcyclotetrasiloxane (D4H) as starting materials, hexamethyldisiloxane (MM) as a capping agent and 98% sulfuric acid as a catalyst. In the second step, hydrosilylation method was used to synthesize the target product, low hydrogen silicone oils and 1,2-epoxy-4-vinylcyclohexane as a starting material and a chloroplatinic acid-isopropanol as catalyst. The synthetic epoxy modified silicone oil was characterized by IR and NMR spectra, which proved that both synthetic routing and its molecular structure was correct.
