A preparation device for phase-change temperature-regulating plastic-wood laminated composite board

Abstract

The invention discloses a making apparatus of a phase changing and temperature adjusting plastic and wood laminated composite board. The apparatus comprises an extrusion feeding device, a current collector, a lamination device, a boundary forming device and an extrusion molding device, the extrusion feeding device, the current collector, the lamination device, the boundary forming device and the extrusion molding device are sequentially connected in series, and a plastic and wood material and a polymer material go through the melt extrusion feeding device and the current collector to form a lamination device multilayer laminated composite material; and the laminated composite material melt enters the boundary forming device, the upper side and the lower side of the channel of the boundary forming device are provided with a plurality of rows of pins, a surface layer material is scratched by the pins when the melt forward flows, the original layer array structure is destroyed, and the surface layer changes from the layered material to a mixed material. The outermost layer of the board obtained by adopting the apparatus is destroyed, and external layer boundary layers are mixed, so when the surface layer is worn in the use process, the mixing of the external layer boundary layers thickens the external surface layer, and the surface treatment in the use process is easy.

Description

technical field [0001] The invention belongs to the field of composite materials, and relates to a preparation device for a phase-change temperature-regulating plastic-wood laminated composite board, in particular, a novel nano-laminated composite material preparation method is used to prepare a plastic-wood laminated composite board, which can greatly improve the strength of the material. Strength, moisture resistance, flame retardancy, etc. Background technique [0002] With the continuous development of society and the continuous improvement of people's quality of life, people have higher and higher requirements for the comfort of the indoor environment. Many home decorations have begun to use wooden floors. At present, the wooden floor on the market is mainly divided into two categories: solid wood floor and plastic wood floor. However, the price of solid wood floor is high and it destroys the country's forest resources, resulting in a great waste of resources. If the p...
