Fireproof aluminum-plastic panel for advertisements

[0016] After weighing each raw material according to the data corresponding to Examples 1-4 in Table 1, add it to a high-speed mixer and stir, control the rotation speed at 800r / min, stir at a temperature of 80°C, and stir for 60 minutes, and then extrude through a screw extruder to produce pellets, extruded at 200°C, cooled, and pelletized to obtain the PE board core material of Examples 1-4.

[0017] Then, the above-mentioned PE board core material was prepared into a PE board with a thickness of 4 mm according to a conventional method. 5A06 aluminum plates with a thickness of 0.3 mm are compounded on the upper and lower surfaces of the PE plate to obtain the aluminum-plastic plate for fireproof advertising of the present invention.
