Abstract
The invention provides a proportioning and a making method of silicon-containing wax emulsion used in polyurethane aqueous release agent. The method is as follows: emulsion is formed when the mixed components of silicon-containing wax are heated to 10 to 30 DEG C above the melting point of wax inside a stirring sealed pressurized reaction kettle; moreover, heat preservation is carried out 15 to 30 minutes at the highest temperature during continuous stirring and cooling. The wax in the mixed components of silicon-containing wax is characterized in that the wax at least comprises oxidized polyethlene wax and/or synthetic ester wax and/or synthetic acid wax, while the silicon is characterized in that the silicon comprises silicon polymer with a hydroxyl group, polyoxyethylene nonyl phenyl ether (or polyoxyethylene tallow amide), KOH (or glacial acetic acid) and water; moreover, the mass ratio of the silicon and wax in the mixed components of silicon-containing wax is between 0.5:1 and 10:1 with the best ratio ranging between 1:1 and 10:1.
