Problems solved by technology

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 and the production efficiency is low, and the cost is high

Abstract

The invention relates to a production process of a plastic decorative board and belongs to the technical field of plastic processing. The production process of the plastic decorative board comprises the following steps: (1) batching; (2) mixing the raw materials according to the mass percentage, and cleaning and crushing; (3) drying the raw materials at a drying temperature of 80 to 100 DEG C witha drying time of 4 to 6 hours; (4) adding the dried raw materials into an injection molding machine to complete injection molding of a product; (5) cooling: using cooling water to cool a mold, wherein the temperature of the cooling water is 5 to 6 DEG C and flow rate is 0.4 to 0. 5m / s, cooling the mold to room temperature; (6) demolding: detaching an injection-molded plastic decorative plate fromthe mold through the cooled mold; (7) spraying a water-based coating on the surface of the plastic decorative plate. The plastic decorative board has excellent high pressure resistance due to a scientific composition proportion, and is excellent in corrosion resistance and heat resistance, and has a long service life.

Description

technical field [0001] The invention relates to a production process of a plastic decorative board, which belongs 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. Contents of the invention [0003] The technical problem to be solved by the present invention i...
