Embodiment 1
[0038] S1: Pour 4% sodium di-n-butyldithiocarbamate, 4% ethylene oxide ring-opening acid, 8% brominated hydrocarbon, 44% long-chain 42 chlorinated paraffin and 20% refined base oil into the blending kettle , the temperature was 70° C., and the reaction was stirred at a rate of 800 r / min for 45 minutes to obtain a mixed liquid A.
[0039] S2: Using three glass beakers with a stirrer, thermometer and water separation and reflux device, add 3% boric acid, 9% triethanolamine and 8% xylene to the container, set the temperature to 100°C and stir the reaction, toluene and reaction water form The azeotrope is gradually evaporated, and the generated water is separated by a water separation and reflux device. After reacting for 8-9 hours, distill under reduced pressure at 88kPa for 40 minutes to remove the remaining toluene, a small amount of water and excess ethanolamine to obtain solution B.
[0040] S3: Heat the solution A to 85°C, slowly pour the solution B into the mixing tank, and...
