| titleOfInvention | Polyacrylic acid thickener and preparation method thereof |
| abstract | The invention relates to an associative polyacrylic acid thickener used in the processing fields of water-based coating, textile printing, water-based resin coating and the like, and discloses a polyacrylic acid thickener and a preparation method thereof. The method comprises the following steps: raw material preparation, water phase preparation, oil phase preparation, pre-emulsion preparation, inverse emulsion polymerization and emulsion phase inversion. The method effectively improves the electrolyte resistance, acid resistance and alkali resistance of the thickening agent; the intermolecular association of the thickening agent is improved; the copolymerization of the short-chain alkyl ether or hydroxyalkyl ether and acrylic acid is good, the intramolecular association of the thickener cannot be obviously caused, and the ion shielding effect of the thickener can be obviously reduced; the short-chain polyether side chain and the polyether cross-linking are beneficial to improving the hydrophilicity of the thickener molecules and the spreadability of molecular chains of the thickener molecules; the quaternary ammonium cation structure enables the thickener to have certain reverse electrolyte performance and good salt tolerance. |
