Embodiment 1
[0026] Fully stir and dissolve 35 parts of β-naphthalenesulfonate formaldehyde condensate and 30 parts of polyacrylic acid ether polymer in a reaction kettle at 80 degrees Celsius to obtain the first mixture, 4 parts of sodium tripolyphosphate, 5 parts of potassium sodium tartrate , 2 parts of sucrose, 5 parts of cellulose ether, 4 parts of lignosulfonate, 4 parts of acrylic acid, 75 parts of hydrogen peroxide and 4 parts of Glauber's salt are put into a stirrer and stirred, wherein the stirring speed of the stirrer is 2500 rpm, and the stirring time The second mixture was obtained in 75 minutes, and the second mixture was gradually added to the reactor within 4 hours through the peristaltic pump, and stirred while mixing with the first mixture to obtain the third mixture, and the third mixture was kept for 5 hours and kept warm. After completion, naturally cool to room temperature to obtain the material.
Embodiment 2
