Embodiment 1

[0015] First pour the PE plastic into two preheating mixers 1 for preheating, control the temperature at 100°C-160°C, heat up for about 30 minutes before starting up, stir at 200-300r / min for 8-10 minutes, and mix at a time ≤450kg, the uniformly stirred plastic particles are sucked into the hopper of the single-screw extruder 2 by the vacuum suction machine. Extrude from die 3 of the extruder. The plastic melts from the dies 3 of the two single-screw extruders are collected in the same barrel 5 and flow into the T-shaped die 6. The outlet temperature of the T-shaped die 6 is controlled at 190-200 ° C. By adjusting the temperature of the extruded sheet The size of the width of the die head is used to form the plastic core board, and the T-die temperature of the core board is ≥175°C. The extruded plastic core board passes through the upper and lower composite polymer adhesive films and aluminum coils in sequence according to the composite process of conventional aluminum-plasti...

Abstract

The invention discloses a method for preparing an ultra-wide aluminium-plastic composite panel and special devices thereof. The method comprises the followings steps: adopting at least two single screw extrusion machines to simultaneously provide uniform materials for a T-shaped die head; extruding plastic panels in the T-shaped die head; and under the conditions of heating and pressurizing, compositing the plastic panels with upper and lower aluminium coils, thus obtaining the ultra-wide aluminium-plastic composite panel. The special devices comprise at least two single screw extrusion machines, the material outlets of the single screw extrusion machines are converged in the same charging barrel, and the charging barrel is communicated with the T-shaped die head. The ultra-wide aluminium-plastic composite panel (with a width of 1600 to 2000mm) produced by the method of meets the design requirements for large span and large breadth, and embodies an unique design style; meanwhile, the method provided by the invention has the advantages of facilitating the cutting of the panels in various specifications, reducing the waste of odd bits, saving the auxiliary materials such as keels and the like, saving the installation costs, and greatly reducing the possibility of water seepage between the panels.

Description

technical field [0001] The invention relates to a production method of an aluminum-plastic composite board and a device thereof, in particular to a preparation method of an ultra-wide aluminum-plastic composite board and a special device thereof. It belongs to the technical field of building materials. Background technique [0002] The aluminum-plastic composite panel is a new type of material that is processed and compounded by a series of high-temperature and high-pressure composite processes, with aluminum coils that have been chemically treated on the surface and coated with baking paint as the upper and lower surfaces, and the plastic plate layer as the core layer. In recent years, aluminum-plastic composite panels have increasingly become an emerging and important industry, receiving great attention from architectural decoration and all walks of life, especially as a new type of curtain wall material. However, due to the limitations of existing production equipment an...
