Abstract

A magnesium plastic composite board is used for architectural ornament and decoration. The magnesium plastic composite board is prepared from a magnesium alloy panel (1) coated by an organic coating on an outer surface and a back aluminum alloy base plate (5) by continuous hot pressing compounding through polymer bonding films (2), (4) and an intermediate plastic core member (3). The composite board combines decoration and function, and has the advantages of light weight, high specific strength and stiffness, corrosion resistance, impact resistance, recess resistance, seismic resistance, noise reduction and electromagnetic shielding function. The composite board is applicable to the fields of partition wall material of airplanes and ships, manufacturing of light train cabinet, electromagnetic shielding engineering and architectural decoration.

Description

technical field [0001] The invention relates to a magnesium-plastic composite board for building decoration materials, belonging to the technical field of building materials. Background technique [0002] Aluminum-plastic composite panels have been widely developed and used as building decoration materials. However, the decorative performance of aluminum-plastic composite panels is outstanding during use, while the performance of functional applications is single, and there are certain limitations. Aluminum-plastic composite panels still exist. [0003] Low strength, poor rigidity and other shortcomings. [0004] Magnesium alloy is the lightest metal among practical metals. The specific gravity of magnesium is 1.74g / cm3, which is 2 / 3 of that of aluminum. [0005] The tensile strength of 5005 is 145-185Mpa, while the tensile strength of magnesium alloy grade AZ40M reaches 230MPa; the tensile strength of magnesium alloy is 40-60% higher than that of aluminum alloy, and the s...
