Problems solved by technology

[0003] Foamed PVC board has the characteristics of waterproof, flame retardant, acid and alkali resistance, moth resistance, light weight, heat preservation, sound insulation, shock absorption, etc. Compared with rigid PVC, the cost is low, and it is an ideal substitute for wood, aluminum, and composite boards. Especially in building exterior wall panels and interior decoration, it is widely used, but the surface hardness of traditional foamed PVC panels is too low, and it is easy to deform after a long time of use.
In order to enhance the use characteristics of foamed PVC boards, there are currently foamed PVC boards coated with A

Abstract

The invention relates to the technical field of sheet material production and particularly relates to a PVC (Polyvinyl Chloride) decorative plate. The PVC decorative plate is characterized in that foamed PVC serves as an inner core body of a plate body, and the outside surface of the foamed PVC is coated with a hard PVC external surface layer. A production process for the PVC decorative plate comprises the following steps: 1) mixing, 2) cooling, 3) impurity removal, 4) heating, 5) pressurizing, 6) coating, 7) cooling, 8) side edge optimizing, 9) surface beautification, 10) unit cutting, and 11) packaging. The PVC decorative plate and the production process thereof have the beneficial effects that the PVC decorative plate is resistant to corrosion and is high in impact strength, stable in size, good in weather resistance, light in weight, low in cost and good in economic benefit; and the product quality is improved.

Description

Technical field [0001] The invention relates to the technical field of plate production, in particular to a PVC decorative plate, a production process and a used mold. Background technique [0002] PVC board polyvinyl chloride plastic is a polymer formed by free radical polymerization of vinyl chloride monomer. The English name is polyviny chloride, or PVC for short. Among them, the foamed PVC board is also called Chevron board and Andy board, and its chemical composition is polyvinyl chloride, so it is also called foamed polyvinyl chloride board. [0003] Foamed PVC board has the characteristics of waterproof, flame retardant, acid and alkali resistance, mothproof, light weight, heat preservation, sound insulation, shock absorption, etc. Compared with rigid PVC, it has low cost and is an ideal substitute for wood, aluminum, and composite boards. Especially, it is widely used in building exterior wall panels and interior decoration. However, traditional foamed PVC panels have prob...
