Description

Waterproof non-deforming drawing board

Technical Field

The utility model relates to an art trade specifically is a waterproof indeformable drawing board.

Background

In water-soluble pigment paints such as watercolor paints, gouache paints, traditional Chinese paintings, acrylic paintings and the like, all pigments contain moisture. When the pigment is painted on the paper, the painting paper swells due to water absorption and expansion, so that the unevenness is caused, and the painting effect is influenced. Therefore, the paper is often required to be mounted and then drawn. Whereas the backing paper is most often wet kraft paper tape. After the drawing paper fully absorbs water and expands, the drawing paper is fixed on the drawing board by using the wet kraft paper adhesive tape, and after the moisture on the drawing paper is dried up, the drawing paper is tightened due to dehydration. At the moment, the painting paper is drawn again, so that the painting paper cannot be uneven, and the painting effect is good.

At present, the current drawing board mostly adopts wooden material to make, and wooden material absorbs water can expand, and the dehydration can shrink, meets water repeatedly and can warp, for example fracture and uplift etc. and life is short, influences the drawing effect, and the clearance remains wet water kraft paper sticky tape very difficult. Still other panels cannot be papered with wet kraft tape. Therefore, the water-resistant non-deformable drawing board is improved.
