摘要：
The epoxy resin and epoxidized polybutadiene were used to prepare the emulsion type epoxy sizing agent for carbon fiber by phase inversion emulsification method. Effects of weight ratio of mixed emulsifiers and emulsifiers/resin (omega(e/r)), shear rate and dripping speed of water on properties of emulsion were investigated by centrifugal sedimentation analysis, particle size analysis and zeta potential measurement. Results showed that the optimal emulsion was obtained when weight ratio of polyoxyethylene nonylphenol phosphoric ammonium (NP-10A) and polyoxyethylene styrenated phenol ether (602) was 2:1, omega(e/r) was 12%, shear rate was 10000 r/min. Conductivity of emulsion by different omega(e/r) was also investigated to represent the variation of conductivity during emulsification process.
