When using, gloves and protective glasses should be worn to avoid direct contact with the skin and eyes. If it gets on the skin, rinse with water and soap. Place in a cool and dry warehouse to prevent exposure to sunlight and rain.
Firstly, 33.8 parts of stearic acid and 6.8 parts of diethylenetriamine are put into a reactor, filled with nitrogen gas, heated and melted, and then continued to rise to 140 ℃. Then, within 2 hours, the temperature is raised to 260 ℃, and the reaction is held for 2 hours. Take samples to determine the freezing point. The reaction ends when the freezing point is greater than 70 ℃. Cool to 100 ℃ and add sodium bisulfite solution, glacial acetic acid, and sodium acetate aqueous solution until the solid content exceeds 20%. Stir it into a slurry to obtain the finished product.
