This invention discloses a method for producing aerosol for cooling automobiles. The aerosol comprises: wine 30-95 wt. %, ethyl acetate 4.8-69.8 wt. % and essence 0.2 wt. %. The method comprises: (1) alcoholing the wine to remove impurities; (2) adding ethyl acetate; (3) adding the essence, mixing, filling into a pressure aerosol tank and sealing; (4) controlling the temperature of the working chamber to be 25-30 deg.C, opening the valve, pumping into a mixture of CO2 and dimethylether at a ratio of 3.8: 6.2 until the pressure in the aerosol tank is 0.3-0.4 MPa, and installing the nozzle. When sprayed, the aerosol can rapidly cool high-temperature subjects in automobiles such as seats and steering wheels, and is safe and nontoxic. |
