DISPERSION AND/OR GRINDING AGENT FOR AQUEOUS MINERAL SUSPENSIONS WITH A ZETA POTENTIAL CLOSE TO ZERO, AQUEOUS SUSPENSIONS CONTAINING SAME, AND APPLICATIONS. |
摘要 |
Water-soluble, amphoteric grinding and/or dispersion agent for aqueous mineral suspensions with the formula (I) having the general form: -(A)p-(B)q-(C)r, where (A) is an anionic ethylene monomer with carboxylic function, (B) is a non-ionic ethylene monomer, (C) is a cationic ethylene monomer comprising at least two oxyalkyl groups, and where: p ranges from 35 to 65 % by weight with respect to the total weight of monomers; q ranges from 20 % to 60 % by weight with respect to the total weight of monomers; r ranges from 5 % to 20 % by weight with respect to the total weight of monomers; and p + q + r = 100 % of the total weight of monomers. The described agent provides for the preparation of aqueous suspensions of mineral fillers and/or pigments with a zeta potential close to 0, a concentration at least equal to 50 % by weight of dry matter, which are suitable for use in the fields of paper, paints and plastic materials. |
