Brushwork sheet paper with edge cover brushwork paper and method for producing the same

Abstract

The invention relates to a painting paper board with edge cover painting paper and a preparation method thereof. Mounting board layers are attached to the upper surface and the lower surface of a supporting plate layer through first adhesive layers; a painting paper layer is attached to the surface of the mounting board layer on the upper surface of the supporting plate layer through a second adhesive layer; the side edge of the supporting plate layer is coated by the painting paper layer, and the painting paper layer extends to the margin of the mounting board layer on the lower surface of the supporting plate layer; and the margin of the mounting board layer on the lower surface of the supporting plate layer is contained in the painting paper layer; a backing paper layer is attached to the mounting board layer on the lower surface of the supporting plate layer through a third adhesive layer; the margin of the backing paper layer is connected with the painting paper layer on the lower surface of the supporting plate layer; and the supporting plate layer is made of foaming polystyrene foam. The production of the invention does not use wood as raw material, thereby saving a large amount of wood, reducing forest lopping and consumption, and protecting ecology environment.

Description

technical field [0001] The invention discloses a drawing cardboard with edge-wrapped drawing paper, and also discloses a preparation method of the drawing cardboard with edge-wrapped drawing paper. Background technique [0002] In the prior art, the support materials of the drawing cardboard all use wood such as pine, Chinese fir, paulownia wood, etc., and the production method is to nail the drawing paper on the supporting frame made of wood with staples or round nails to make a painting frame. In the product composition, wood accounts for about 40% of the total product price, and a large amount of wood is consumed in the production process. A large amount of wood needs to cut down and consume forests. Forests are important natural resources for climate regulation and water and soil conservation. Excessive felling will cause damage to the ecological environment and soil erosion, leading to the trend of desertification on the earth; in addition, products use wood as supports...

Problems solved by technology

A large amount of wood needs to cut down and consume forests. Forests are important natural resources for climate regulation and water and soil conservation. Excessive felling will cause damage to the ecological environment and soil erosion, leading to the trend of desertification on the earth; in addition, products use wood as supports, and wood The density is higher, so the mass is larger and the product is heavier
