Abstract

The invention is a foam Mg plastic composite preparing method, including techniques of preparing foam Mg backing material and protecting surface, and its characteristic: firstly making foam Mg material into a 3D-connection prefab at hole diameter of 1-5mm, placing the prefab in a mould to preserve heat at 150-350deg.C, vacuumizing, and injecting and filling to make it at once. It has metallic mechanical property, and plastic manufacturability, functionality and artistry. It can be designed and made into various formal patterns. Its surface plastic layer makes it have excellent manufacturability and corrosion resistance. It is an ideal material on many occasions.

Description

technical field [0001] The invention relates to metal material processing, in particular to the preparation process of foamed magnesium plastic composite materials. Background technique [0002] With the improvement of people's living standards and the development of industry, it is urgent to develop new materials that are lightweight, anti-deformation, anti-aging, and have good electromagnetic shielding effects. Such as: used for interior decoration ceiling boards, shielding boards, sound insulation boards under special venues, etc. Magnesium alloy is the lightest metal structural material. It not only has similar mechanical properties to aluminum alloy, but also has the function of being lighter and more shielding. However, pure foamed magnesium material has poor processability and corrosion resistance. Contents of the invention [0003] The purpose of the present invention is to provide a preparation process of foamed magnesium plastic composite material with good pr...
