Abstract
The invention belongs to the technical field of driers, and particularly relates to an aqueous composite drier and a preparation method thereof. In the composition provided by the invention, metal salts have a certain promotion effect with each other, so that an intermolecular structure tends to be developed towards a direction of water solubility, then a stable state structure with good water solubility is formed, and dissolution in water is facilitated. According to the invention, cobalt ions, zirconium ions and calcium ions are added into the composition, and uniformity of surface drying and interior drying is established in a paint film through a synergistic effect among different metals, so that stability of paint storage is improved, and leveling property, gloss property and hardnessof the paint film are improved. According to the invention, activity of the cobalt ions can be increased through existence of a zirconium salt drier and a calcium salt drier, drying ability of the composition is improved, and thus the paint film can be quickly dried; and through addition of a calcium salt, the composition is not easily oxidized or reduced, and can be adsorbed on the surface of apigment filler, so that the drying speed of the whole system is slowed down after the drier is adsorbed by the pigment filler.
Description
technical field [0001] The invention belongs to the technical field of drier, and in particular relates to a water-based composite drier and a preparation method thereof. Background technique [0002] In the prior art, there is a big problem with the effect of a single drier, and it also has a great impact on the coating. The side effects of the drier during the use of the coating include problems such as too fast surface drying and hard drying. [0003] Therefore, it is imperative to develop a water-based composite drier that has strong water solubility, short surface drying time and does not affect the chroma of the paint film! Contents of the invention [0004] The present invention aims at the deficiencies in the above-mentioned prior art, and provides a water-based composite drier and a preparation method thereof. [0005] The technical scheme of the present invention to solve the above-mentioned technical problems is as follows: an aqueous composite drier, the compo...
