sodium bisulfite pulping waste liquid of wood is desugared and converted to obtain sodium lignosulfonate. Add it to the condensation kettle, add formaldehyde aqueous solution, then add acid in the amount of catalyst, seal the reactor, charge with nitrogen, and react at 2.0 MPa for 2 h. Then transfer it to the neutralization kettle, add dilute alkali to adjust the pH value to about 10. Remove inorganic salts, concentrate into a slurry, and spray dry to obtain the finished product. M-10,M-11,M-13,M-14,M-15,M-16 and M-17 are prepared according to requirements.
