In an implementation, please refer to fig. 2 specifically, a novel UV nano-projection writing whiteboard composite board includes at least a substrate layer 1 and a paint layer 2. The coating layer 2 is arranged on one side of the substrate layer 1, and the coating layer 2 is formed by roll coating of water-based UV coating, so that the coating layer 2 has extinction and anti-fouling performance.

It is noted that the aqueous UV coating may include aliphatic polyurethane hexaacrylate, titanium dioxide, dipentaerythritol, and silicone materials, and may be mixed in the manner of 40% -50% aliphatic polyurethane hexaacrylate, 10% -15% acrylate, 20% -30% dipentaerythritol hexaacrylate, 5% -8% titanium dioxide, and 3% -7% silica. The aliphatic polyurethane hexaacrylate, the titanium dioxide, the dipentaerythritol and the organic silicon can refer to the prior art, and are not described herein again. In addition, after the water-based UV coating is roll-coated, an ultraviolet curing process can be carried out for baking, and the forming is accelerated.

When the water-based UV coating is coated on the substrate layer 1 in a rolling way, a high-hardness matte antifouling layer, namely the coating layer 2 in the application can be formed on the surface of the substrate layer 1, so that the surface of a finished product prepared by the coating has the performances of extinction and antifouling, namely, a whiteboard can achieve the triple effects of no reflection in projection and no residual shadow and stain in a writing easy erasing test. Therefore, the whiteboard can be used as a writing board and a projection board at the same time, and the use cost of the teaching equipment is saved. The problem that the projection panel in the education industry is not suitable for ink pens and is difficult to clean is solved.

Meanwhile, the paint layer is formed by roll coating of water-based UV paint, and the problems that rough chalk of a color drawing baking varnish steel plate panel is generally adopted in the industry, writing dust is large, and water-soluble chalk cannot be used for writing can be solved. The chalk has high hardness and good stain resistance of the board surface, and combines the dry and the dry actions of common chalk and the wet and easy cleaning action of water-soluble chalk.

Of course, the water-based UV material may be formed by spraying, plating, or the like, besides the roll coating method, and will not be described herein again.

The base layer 1 is generally used in the form of a substrate, which may be at least one of a density board, a particle board, and a metal honeycomb board.

In practical application, the thickness of the substrate layer 1 is 9-20 mm; the thickness of the paint layer 2 is 30-40 μm.

Referring specifically to fig. 4, in an implementation, in order to make one side of the substrate layer 1 exhibit a color effect, the above structure may further include a colored layer 3. The coloured layer 3 is located between the base layer 1 and the paint layer 2, thereby changing the colour of the base layer 1 side. The colored layer 3 may be white or black, and is not limited thereto.

Further, the side of the coloring layer 3 close to the paint layer 2 is provided with a rough surface, so that the stability of the paint layer 2 attached on the coloring layer 3 is improved.

In an implementation mode, the rough surface can be achieved in a roughening mode. In another practical embodiment, the colored layer 3 is formed by mixing at least color paste and hydroxyl modified polysiloxane compound and then rolling. Among them, the hydroxyl-modified polysiloxane compound can form a very strong orientation adsorption layer on the surface of the colored layer 3, thus improving the adhesion stability of the paint layer 2 on the colored layer 3.

In an implementation embodiment, please refer to fig. 1 specifically, a sealing portion 4 is further disposed around the substrate layer 1, and the sealing portion 4 covers the periphery of the substrate layer 1. The edge sealing part 4 is formed by adopting the edge sealing of a laser edge sealing strip, so that the use of the metal frame which originally adopts the mode of combining the metal frames is saved, the complex installation procedure in the later period is simplified, and the manufacturing cost of enterprises is greatly reduced.

Further, the colored layer 3 and the seal portion 4 are in the same color. Therefore, the overall color of the finished product is consistent, and the attractiveness of the product is improved.

Consider the two-sided use of a whiteboard. In an embodiment, as shown in fig. 3, the substrate layer 1 is provided with a paint layer 2 on both sides. Thereby enabling the whiteboard to be used on both sides.

Further, as shown in fig. 5, a coloring layer 3 is disposed between each of the paint layers 2 and the substrate layer 1.

Meanwhile, the paint layer is formed by roll coating of water-based UV paint, and the problems that rough chalk of a color drawing baking varnish steel plate panel is generally adopted in the industry, writing dust is large, and water-soluble chalk cannot be used for writing can be solved. The high-hardness water-soluble chalk has high hardness and good antifouling performance on the board surface, and combines the dry and friction of common chalks and the wet and easy cleaning of water-soluble chalks.

The above description is only exemplary of the present application and should not be taken as limiting the present application, as any modification, equivalent replacement, or improvement made within the spirit and principle of the present application should be included in the protection scope of the present application.
