Problems solved by technology

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 in use. flaking phenomenon
Therefore, it cannot meet the needs of customers, nor meet the requirements of environmental protection, energy saving, and emission reduction.
[0005] There are also some water-based paints, although they are environmentally friendly paints, they cannot meet the anti-graffiti performance (handwriting, one-wipe and clean performance), so they cannot be used as whiteboard wall paint

Abstract

The present invention provides an aqueous whiteboard paint, which has the anti-graffiti performance of solvent-based coatings, is also a water-soluble environmental-friendly paint, is low in VOB and easy to operate, meets environmental requirements, and achieves the purposes of environmental protection, energy saving, and emission reduction. The technical solution is that: the aqueous whiteboard paint includes a component A and a component B, the component A and the component B are mixed and stirred uniformly as the mass ratio of 1:3-6. The paint helps to effectively solve the problem that whiteboards are needed to be hung on walls for writing in schools, offices and homes. The paint can replace the whiteboard, the wall can be freely written and can be cleaned by wiping. The teaching, work, and life become convenient, and the teaching and office costs are dramatically reduced. The product is very environmental-friendly, and helps to achieve energy saving and emission reduction purposes. The paint can be widely used in schools and offices, eliminating the need for hanging whiteboard, and reducing solvent emissions.

Description

technical field [0001] The invention relates to the technical field of wall paint, in particular to a water-based whiteboard wall paint. Background technique [0002] At present, in the application field of whiteboard paint, most of them are borrowed from ordinary wall paint, and there are some problems like this. One is that wall paint has good anti-graffiti performance and can be used as whiteboard paint, but they are all solvent-based paints, which are not environmentally friendly and do not meet the requirements of a low-carbon economy. They go against the general trend of environmental protection, energy saving, and emission reduction. Users are also unwilling to choose. The other is that although water-based wall paint is environmentally friendly, if it is used as a whiteboard paint, the anti-graffiti performance cannot meet the requirements, and it is not used as a functional paint. [0003] Existing whiteboard paints are divided into two categories, one is industri...
