Description

Technical Field

[0001] The utility model relates to the technical field of drawing board pads, in particular to a PVC leather drawing board pad with adhesive backing. Background Art

[0002] On a technical level, painting is a process of using a surface as a support and then adding color on it. Those surfaces can be paper or cloth. The tools for adding color can be brushes, sponges, or cloth strips. The drawing board is a flat plate often used to pad drawing paper when painting. It is often placed on an easel, and some people paint on their knees. In the process of using a drawing board, a drawing board pad is often used.

[0003] After searching, a PVC leather drawing board pad with adhesive backing (CN216423958U) is found, which includes a drawing board pad body, a plastic film is arranged at the bottom end of the drawing board pad body, a second adhesive layer is arranged on the upper part of the plastic film, an adhesive film layer is adhered on the upper part of the second adhesive layer, a first adhesive layer is adhered on the upper part of the adhesive film layer, and a PVC leather layer is adhered on the upper part of the first adhesive layer. In the utility model, firstly, the leather thickness is 2 mm, the hardness is suitable, there is no soft feeling when painting, it is comfortable to use, it has a good covering effect on the damage of the drawing board, keeps the drawing paper flat, can effectively buffer the force of the drawing board, and has a certain protective effect on the drawing board. At the same time, a double-sided adhesive film is used on the back of the PVC leather layer. The adhesive is environmentally friendly and has a long-lasting adhesive force. It can be pasted by removing the sealing film. It is quick and convenient to use. There is no need to repeatedly fix the drawing board pad with tape or clips. When using it, the drawing board pad with adhesive backing only needs to remove the adhesive film and stick it to the drawing board.

[0004] However, since most drawing board pads lack hardness during use and are inconvenient to fix on the hand, the drawing board pads are easy to fall off when painting outdoors. After falling many times, the drawing board pads are prone to bending. In view of this, we propose a PVC leather drawing board pad with adhesive backing. Utility Model Content
