Abstract

The invention discloses a water-based negative ion coating and a preparation method thereof. The preparation method comprises the following steps: adding a mixture of tourmaline powder, a cerium compound and polymerizable boric acid ester into a polyethylene glycol aqueous solution, and performing uniform dispersion under ultrasonic waves to obtain a suspension A; mixing the suspension A and a propylene monomer, and performing emulsion polymerization to obtain an emulsion B; and uniformly mixing the emulsion B, a cationic block copolymer, a polymer emulsion and an alcohol organic solvent, adding tetraethyl orthosilicate, and performing stirring to obtain the coating. The water-based negative ion coating provided by the invention can slowly release negative ions for a long time, has a higher release quantity of the negative ions, exhibits long-term environmentally-friendly performance, and has excellent water washing resistance and washing resistance and higher bonding strength, and acoating layer does not easily fall off.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a water-based negative ion coating and a preparation method thereof. Background technique [0002] Negative ion paint is an advanced environment-friendly functional paint, which can release negative ions in the air, and has the functions of fresh air, deodorizing, antibacterial and sterilizing, anti-oxidation, and clean air. Negative ion coatings have broad application prospects, but although the existing negative ion coatings can generate negative ions, their durability is not good, especially after the negative ions are released in about 5 days after coating, the effects of fresh air and antibacterial sterilization cannot be achieved. Contents of the invention [0003] In view of this, the invention provides a water-based anion coating and a preparation method thereof. The water-based negative ion coating of the present invention can release negative ions slowly for a long time, and ...
