| titleOfInvention | Low-conductivity cooling liquid and preparation method thereof |
| abstract | The invention discloses a low-conductivity cooling liquid and a preparation method thereof, wherein the cooling liquid comprises the following raw materials in parts by weight: 10-50 parts of deionized water, 50-90 parts of ethylene glycol, 0.01-10 parts of multi-effect compound preservative and 0.001-0.1 part of defoaming agent; the multi-effect compound preservative is prepared from the following components in percentage by mass of 1: (0.1-2): 1, poly-tricarboxylic acid and dicarboxylic acid. The preparation method comprises the following steps: A. mixing qualified deionized water and ethylene glycol at the temperature of 20-60 ℃, and stirring for 10-30 minutes to form a solution 1; b: mixing polyether, poly-tribasic carboxylic acid and dicarboxylic acid in the multi-effect compound preservative according to a certain proportion at the temperature of 50-70 ℃, and stirring for 30-60 minutes; c: adding a multi-effect compound preservative and a defoaming agent into the solution 1 at the temperature of 50-70 ℃, and stirring for 30-60 minutes to form a solution 3; d: and filtering the solution 3 through cation exchange resin to obtain the product. The cooling liquid has the characteristics of low conductivity, good corrosion resistance and good rubber compatibility. |
