Abstract
The invention relates to a production process of a high-strength plastic decorative plate, and belongs to the technical field of plastic processing. The production process of the high-strength plasticdecorative plate comprises the following steps: (1) preparing raw materials; (2) mixing the raw materials according to mass percentage, cleaning and pulverizing; (3) performing drying treatment on the raw materials; (4) adding the dried raw materials into an injection molding machine to complete injection molding of a product; (5) cooling; (6) demoulding; (7) putting one layer of steel wire net in the middle of two layers of plastic plates and performing adhesion through adhesive; (8) cutting the plastic plate after adhesion, and mounting an aluminum alloy frame at the periphery of the cut plastic plate; (9) electroplating a pure aluminum plating layer; and (10) guaranteeing the high-strength plastic decorative plate to enter a storage. The high-strength plastic decorative plate has excellent high-pressure resistance due to scientific component proportion, has excellent corrosion resistance and heat resistance, and has long service life. One layer of steel wire net is placed in the middle of the two layers of plastic plates to perform adhesion, so the mechanical strength of the high-strength plastic decorative plate is greatly enhanced.
Description
technical field [0001] The invention relates to a production process of a high-strength plastic decorative board, belonging to the technical field of plastic processing. Background technique [0002] There are many kinds of decorative materials, including stainless steel decorative materials, plastic decorative materials, and composite board decorative panels, each of which has its own characteristics. Among them, the plastic decorative board is the most widely used. When the usual plastic decorative board is processed, some are formed by extrusion, and some are formed by injection molding. Usually, it is easy to appear at the nozzle (glue point) during injection molding. Cold material Spots, silver streaks, air marks, and other appearance defects. The injection molding process cannot be stabilized, the product quality is unstable, the production efficiency is low, and the cost is high.
