The invention discloses a paraffin 
emulsion with ultrahigh 
solid content, which comprises 30%-40% of water, 54%-65% of paraffin, 2%-3% of emulsifying agent, 0.5%-1% of amphiphilic nano particle, and 1%-2% of poval or 
hydroxyethyl cellulose, wherein the emulsifying agent is 
fatty alcohol-
polyoxyethylene ether and / or glycerin 
fatty acid ester, and the amphiphilic nano particle is hydrophobic modified nanometer 
silicon dioxide or nanometer 
silicon nitride. According to the paraffin 
emulsion, the amphiphilic nano particle and the macromolecular stabilizing agent are added and are used for stabilizing the paraffin 
emulsion with ultrahigh concentration together with the micro-molecular surface 
active agent, so that the 
solid content of the paraffin emulsion is increased, the stability of the paraffin emulsion is enhanced and the 
viscosity of the paraffin emulsion is reduced. The 
apparent viscosity of the paraffin emulsion provided by the invention at normal temperature is 200-350mPa.s and is lower than the 
viscosity of the frequently used paraffin emulsion at present. The dosage of the micro-molecular surface 
active agent, namely, the emulsifying agent, is reduced.
