Abstract

The invention relates to the field of coatings and particularly relates to scrub-resistant paint for a blackboard and a preparation method of the scrub-resistant paint. The scrub-resistant paint for the blackboard contains the following components in percentage by weight: 60%-70% of water-based acrylic resin, 10%-15% of water-based amino resin, 5%-10% of water-based scrawl resin, 3%-5.8% of an aid and 5%-10% of deionized water. The scrub-resistant paint is prepared by mixing and stirring the components. The scrub-resistant paint has the characteristics that the VOC content is low, the smell is low, the adhesive force is strong, the solvent resistance is strong, the anti-scrawl effect is obvious, and the repeated pollution and scrubbing durability is good; and the scrub-resistant paint is environmentally friendly.

Description

technical field [0001] The invention belongs to the field of coatings, in particular to a scrub-resistant blackboard paint and a preparation method thereof. Background technique [0002] At present, blackboard paints on the market are basically oil-based products. Water-based blackboard paints are more environmentally friendly than traditional solvent-based blackboard paints. Water-based paints can be applied by blending with water. The indispensable diluents and curing agents in paints contain a lot of toxic ingredients, and the environmental protection of water-based paints is that no diluents and curing agents are needed. [0003] The existing paints are mainly solvent-based, which need to solve the problems of high VOC content, serious pollution and fire hazards; the existing water-based paint products have very high VOC, and water-soluble acrylic resin amino baking varnish is generally used. The VOC is as high as 300g / L and the odor It is also very large; the gloss and...
