The invention provides a preparation method for a heatstroke preventing and temperature lowering beverage for an electric power operator. The method adopts aloe leaves and mint as raw materials and comprises the following steps: 1, treating raw materials, taking 50 kilograms of the fresh aloe leaves and 30 kilograms of the fresh mint stem leaves, cutting the aloe leaves and the mint stem leaves into powder by using a cut-off machine, and then adding the powder of the aloe leaves and the mint stem leaves into a pulping machine to be pulped for spare use; 2, mixing the materials, adding 500 kilograms of water to the spare pulp, stirring and filtering the mixture of the water and the spare pulp, removing residues, and taking serosity for spare use; 3, compounding, taking 100 kilograms of the serosity, adding 0.5 kilogram of sodium chloride, 0.5 kilogram of potassium chloride and 0.1 kilogram of vitamin C to the serosity, then stirring and dissolving the mixture of the sodium chloride, the potassium chloride, the vitamin C and the serosity, filtering the mixture of the sodium chloride, the potassium chloride, the vitamin C and the serosity which is stirred and dissolved, filling the mixture of the sodium chloride, the potassium chloride, the vitamin C and the serosity which is filtered after filtering, and performing bus sterilizing on the mixture of the sodium chloride, the potassium chloride, the vitamin C and the serosity which is filled to obtain finished products. The heatstroke preventing and temperature lowering beverage for the electric power operator prepared by the method disclosed by the invention has heatstroke preventing and temperature lowering effects, symptoms caused by the solar illumination and the high temperature are prevented from occurring, and the beverage is beneficial to the health and suitable for being applied as the heatstroke preventing and temperature lowering beverage for the electric power operator.
