Problems solved by technology

[0003] The existing commercially available whiteboards are basically high-gloss due to technical reasons. Because the gloss is too high, diffuse reflection cannot be formed well, and reflections may not be seen clearly during use in conference rooms and classrooms, and most After a long time of use, the whiteboard will not be wiped clean, which will seriously affect the use effect

Abstract

The invention discloses a full-angle diffuse reflection matte white board coating and a preparation method thereof. The coating is prepared from the following raw materials in parts by weight: 10-40 parts of hardening resin, 10-40 parts of acrylic acid modified high-performance polyester resin, 1-10 parts of surface energy control resin, 5-20 parts of a solvent, 5-20 parts of a cross-linking agent, 0.3-2 parts of a leveling agent, 0.1-2 parts of a defoaming agent, 0.3-1 part of a catalyst, and 1-8 parts of matting powder. The preparation method of the coating comprises the following steps: adding the hardening resin, the acrylic modified high-performance polyester resin, the surface energy control resin and the solvent into a stainless steel cylinder, and starting stirring; reducing the stirring speed, stirring at a low speed, adding a cross-linking agent and a catalyst, and then stirring at a medium speed; reducing the stirring speed, stirring at a low speed, adding a leveling aid and a defoaming aid, and then stirring at a medium speed; and after stirring, filtering with a filter bag to obtain the coating. The matte white board coating disclosed by the invention is coated on an aluminum coil or a steel coil coated with a white ground color, and an obtained white board has a full-angle diffuse reflection effect.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to an all-angle diffuse reflection matt whiteboard coating and a preparation method thereof. Background technique [0002] The writing board specially used for whiteboard markers has been widely accepted and used by the public because it has the characteristics of being easy to erase and write and can not produce dust. This type of writing board can be used in cultural teaching, office, meeting and other occasions, and its characteristic is that the ink written on the writing board with a whiteboard pen can be erased. [0003] The existing commercially available whiteboards are basically high-gloss due to technical reasons. Because the gloss is too high, diffuse reflection cannot be formed well, and reflections may not be seen clearly during use in conference rooms and classrooms, and most After a long time of use, the whiteboard will not be wiped clean, which will seriously affec...
