Waterborne magnetic whiteboard wall paint

Abstract

The invention relates to the technical field of wall paint and discloses waterborne magnetic whiteboard wall paint. The wall paint comprises a component A and a component B. The wall paint is obtainedby mixing the component A and the component B according to the mass ratio of 1:2-5 and uniformly stirring. The component A comprises (by weight): 65-80 parts of modified epoxy resin, 7-16 parts of adiluent, 6.5-10 parts of a surfactant, and 1.2-4 parts of an accelerant. The component B comprises (by weight): 24-30 parts of a modified amine hardener, 22-33 parts of composite metal iron powder, 18-30 parts of water, 0.15-0.6 part of a dispersant, 0.1-3 parts of a coupling agent, 0.1-0.5 part of a thixotropic agent, 18-34 parts of an extender pigment, 0.3-1.1 parts of a flatting agent, and 0.12-0.38 part of a surfactant. After the magnetic whiteboard wall paint is applied on the wall, the wall can be scrawled freely and will be clean when wiped. Meanwhile, the wall has magnetic force, and materials can be adsorbed on the wall through the magnet, thus making teaching and working to be more convenient. By the use of a waterborne formula, the wall paint is harmless to the environment and people's health and is green and environmentally-friendly.

Description

technical field [0001] The invention relates to the technical field of wall paint, in particular to a water-based magnetic whiteboard wall paint. Background technique [0002] At present, in the application field of whiteboard wall paint, most of them are borrowed from ordinary whiteboard wall paint. Existing whiteboard paints are divided into two categories, one is industrial baking varnish for making finished whiteboards, and the other is solvent-based paint for painting whiteboards on site. There are usually several resin paints for painting whiteboards on site, such as acrylic resin paint, epoxy resin paint, polyurethane resin paint, and fluorocarbon resin paint. The anti-graffiti performance (writing performance) of these types of resin paints on whiteboards can meet the requirements, but because they are all solvent-based paints, the paints are not environmentally friendly, have poor adaptability to the substrate, and are prone to defects in on-site construction and i...

Problems solved by technology

It cannot meet the user's demand for the wall as a whiteboard, and the interaction effect is poor

[0003] There are also some water-based paints. Although they are environmentally friendly paints, they cannot meet the anti-graffiti performance. Therefore, they cannot be used as whiteboard wall paints.
