Abstract

The invention discloses a novel water-based drier, and belongs to the field of driers for coating paint. The novel water-based drier comprises a main drier and an auxiliary drier. The preparation method comprises the following steps of adding an iron-containing precursor, EDTA (ethylene diamine tetraacetic acid) acid and deionized water into a reaction container, and stirring; then, adding zirconium-containing precursor and EDTA, and stirring; adding the deionized water, slowly adding a lanthanum element-containing precursor, and stirring; slowly adding a manganese-containing precursor, continuing to stir for a period of time, standing, and staying overnight; continuing to stir in the second day, and adding the deionized water until no obvious air bubble is formed; adding an acrylic acid emulsion, uniformly stirring, standing, sucking out the upper transparent solution, and reserving the lower emulsion, so as to obtain the required product. The novel drier and the preparation method have the advantages that compared with the existing common drier, the color is lighter; the drying time is obviously shortened; the operation is simple, and the preparation method is suitable for large-scale production.

Description

technical field [0001] The invention relates to the field of paint drier, in particular to a novel water-based drier and a preparation method thereof. Background technique [0002] At present, the driers used in paints and paints are mostly oil-soluble naphthenic acid soaps or isooctanoic acid soaps of metals such as cobalt, manganese, and lead, which have the disadvantages of dark color, high viscosity, heavy odor, and high toxicity. Light-colored paints and water-based paints. With the increasing awareness of social environmental protection and safety, laws and regulations to limit VOC emissions have been introduced one after another, traditional solvent-based coatings are being challenged more and more, and the requirements for the development of water-based coatings are becoming more and more urgent. While the research on water-based coatings continues to advance, the application of driers in water-based coatings has gradually become a new research focus. The market pr...
