Emulsify epoxy resin E-44 with heavy calcium carbonate, light calcium carbonate, aerosil, surface-modified aerosil and bentonite BP-187. The experimental results show that neither heavy calcium carbonate nor light calcium carbonate has emulsifying effect. O/W type emulsion can not be obtained with aerosil and bentonite BP-187. Surfactant-modified aerosil CTAB-SiO2 and DTAB-SiO2 do have emulsifying effect, and they can transform into more stable O/W type emulsion. The synergy between BP-17, EP-1 and CTAB-SiO2 is obvious. Hydrophilic emulsifier EP-1 could be replaced by CTAB-SiO2 or BP-187 completely or partly to prepare stable O/W emulsion. The TEM result show that the disperse phase of the emulsion produced by CTAB-SiO2 and the compound emulsifier of CTAB-SiO2 and BP-187 is irregular floc, and the disperse phase of the aqueous emulsion produced by the compound emulsifier of CTAB-SiO2 and EP-1 is regular globular or ellipsoidal multiple emulsion.
