Porcelain plastic decorative plate and its processing method

Abstract

The invention relates to a decorative plate, and discloses a porcelain plastic decorative plate. The porcelain plastic decorative plate comprises, from top to bottom, a PVC transparent abrasion-resistant layer, a PVC pattern printing layer and a substrate layer which are sequentially stacked. The substrate layer comprises the following components, by weight, 100 parts of PVC resin, 15-20 parts of a plasticizer, 2.0-5.0 parts of a stabilizing agent, 60-70 parts of bead powder, 15-30 parts of a fiber, 5-10 parts of an impact improver, 15-30 parts of stone powder, 0.5-1.5 parts of rosin or PE wax, and a proper amount of a coloring agent. The invention also discloses a processing method of the decorative plate. The method comprises the following technological steps: 1, processing the substrate layer; 2, printing a pattern; 3, carrying out hot-press molding; 4, carrying out surface treatment; 5, carrying out heat treatment; and 6, carrying out product inspection and packaging. The decorative plate has the advantages of stable dimensional stability, low water absorption rate, difficult deformation, difficult shedding and foaming of the decorative layer, rich and colorful pattern, and stereoscopic effect.

[0002] At present, decorative boards have been widely used in the decoration of walls, partitions, and ceilings. Decorative boards can be used for decoration to give a new look. The main decorative materials include natural marble, porcelain tiles, gypsum boards and veneer composite boards. These decorative materials exist Some obvious disadvantages are that natural marble and ceramic tiles are heavy and contain radioactive harmful substances, and the variety of designs and colors is limited. The existing gypsum boards have low bending strength, are easy to deform, yellow, and are not moisture-proof. The use is limited by the region; solid wood The board is flammable, not moisture-proof, and is not a renewable resource; the production process of plywood uses urea-formaldehyde glue containing formaldehyde as an adhesive, and the toxic volatile gas seriously affects human health and even causes cancer. cause more damage

At the same time, most of the current decorative panels are laminated panels, and their surfaces are relatively glossy. They can only be made into a marble-like flat surface, and cannot produce three-dimensional effects. Because the production process of decorative panels on the market is to pass the surface decorative layer through an adhesive. After dipping, it is hot-pressed (cold-pressed) with the bottom layer of the decorative board, so that the surface decorative layer and the bottom layer are closely bonded. In order to achieve the surface wear-resistant effect, a layer of wear-resistant paint is applied on the surface of the decorative board. Paint peels off quickly, reducing service life
