Abstract
The invention discloses a preparation apparatus for a highly-filled stone-plastic composite packaging board. The preparation apparatus comprises the following sequentially-connected systems: a mixingand extruding system, a melt T-die system, a three-layer composite board forming system, a first traction device, a heat treatment tempering furnace device, a composite board setting freezer, a secondtraction device, a tracking and fixed-length shearing machine, an automatic board palletizing machine and an electrical control system for units. The invention also discloses a preparation method forthe highly-filled stone-plastic composite packaging board. The preparation method comprises the following steps: carrying out extrusion, calendering and molding so as to form a middle core layer, wherein the structure of the core layer is a circular truncated cone-shaped or polygonal table-shaped convex-concave honeycomb sheet; and subjecting upper and lower surface layers to thermal lamination,hot pressing and molding with the upper and lower surfaces of the core layer respectively in steps so as to form the composite packaging board. The invention has the beneficial effects that the boardproduced in the invention has excellent physical properties as a whole, shows good bending and tear resistance in both horizontal and vertical directions, does not need any adhesive, and is environmentally-friendly and odorless in the process of production.
Description
technical field [0001] The invention relates to a preparation device and a preparation method of a stone-plastic high-fill composite packaging plate, belonging to the technical field of material machining. Background technique [0002] Corrugated cardboard materials are commonly used in various packaging carton application fields, and the market application of this material is very extensive. However, the production process of corrugated cardboard materials needs to use a large amount of wood pulp resources as raw materials, and the papermaking process will cause a large amount of water pollution and consume a large amount of energy. The entire corrugated cardboard material manufacturing process has very serious environmental protection problems. . [0003] In order to further meet the country's energy-saving, environmental protection and sustainable industrial development requirements, stone-plastic high-fill composite packaging board is a new type of environmentally frien...
