Embodiment 1
[0035] Firstly, 10 parts of methoxypolyethylene glycol acrylate and 17 parts of water were added into the reaction kettle, the temperature was raised to 40 degrees, heated for 30 minutes, and then 0.5 parts of hydrogen peroxide was added at one time. Add 2 parts of acrylic acid to 2 parts of water to make material A; add 0.02 parts of mercaptopropionic acid and 0.02 parts of octyl mercaptan to 4 parts of water to make material B, and add materials A and B dropwise to the above reaction kettle to control the amount of material A After 3 hours of dripping, material B was dripped in 3.5 hours. After the addition was completed, the material was matured for 1 hour. Add sodium hydroxide to the reaction kettle to adjust its pH to 5-7. Add 4 parts of sodium sulfate and 4 parts of ethyl acetoacetate to the reaction kettle, and wait until it is completely dissolved, add 40 parts of triisopropanolamine, 10 parts of triethanolamine and 5 parts of water to prepare an aluminum silicate part...
