Abstract

The invention relates to a waterborne solid color paint, in particular to a waterborne solid color paint for preventing swelling and eliminating formaldehyde on an artificial board. The waterborne solid color paint is prepared by mixing the raw materials by weight percent as follows: 10% to 50% of waterborne resin. 30% to 70% of filler, 0.3% to 2% of formaldehyde absorbent HB-TL, 2% to 5% of alcohol ether solvent, 1% to 3% of thickening agent, 0.1% to 0.5% of defoaming agent, 0.1% to 0.5% of wetting agent, 0.1% to 0.5% of dispersing agent and the balance of water. The waterborne solid color paint can being used for preventing fiber on a middle density fiber board from swelling and obtaining excellent paint film without the construction of a paint filler, has high formaldehyde eliminating rate, is capable of changing formaldehyde emission on the artificial board from Level E2 to Level E0 and has the formaldehyde absorption rate up to 99%.

Description

technical field [0001] The invention relates to a water-based solid-color paint, in particular to a water-based solid-color paint for preventing swelling and eliminating aldehydes on artificial boards. Background technique [0002] Because there are many tiny holes on the surface of the MDF, when the traditional solvent-based paint is applied to the MDF, it is first scraped and coated with pig's blood ash, then coated with shellac paint to seal, and then applied with solvent-based white primer and color paint. . Although a fully enclosed decorative effect can be made, because the formaldehyde in the MDF has a strong slow-release property and extremely small molecules, it is easy to penetrate the paint film and volatilize into the air, and the solvent-based coating itself has harmful solvents volatilization, Considering this approach from an environmental point of view is not advisable. In the construction of water-based paint, due to the short fiber and loose structure of ...
