| titleOfInvention | Nonionic and acidic side group modified 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 paint, textile printing, water-based resin coating and the like, in particular to a polyacrylic acid thickener modified by nonionic and acidic side groups and a preparation method thereof. The method comprises the following steps: preparing raw materials, preparing a water phase, preparing an oil phase, preparing a pre-emulsion, polymerizing an inverse emulsion and carrying out emulsion phase inversion. The method improves the electrolyte resistance, acid resistance and alkali resistance of the thickener; the thickening agent molecule does not contain lateral ester groups due to a plurality of special monomers, and intramolecular hydrogen bond action between hydroxyl and ester groups does not exist, so that intermolecular association of the thickening agent is facilitated; the internal association of thickener molecules is avoided and the copolymerizability of the thickener molecules and acrylic acid is better; the strongly acidic side groups and the "cluster-like" carboxyl structures introduced with the unsaturated polycarboxylic acids are beneficial to improve the acid resistance of the thickener and balance the water absorption and curling properties of the thickener molecules. |
