Abstract
A magnesium particle macromolecule composite material is characterized in composed of macromolecule olefin polymer as substrate which is uniformly distributed with 0.5-50um magnesium alloy particles at the mass percentage of 0<P<=1%, 0<Sr<=0.3%, 0.3%<=Bis<=0.6%, while the left is magnesium, wherein the magnesium alloy particles are 10-35% volume of the composite material. The invention discloses a corresponding preparation method with simple process, stable organism, non pollution and low cost, while the prepared magnesium particle macromolecule composite material has better electromagnetic shield function.
Description
A kind of magnesium particle polymer composite material and preparation method thereof 1. Technical field The invention belongs to the technical field of composite materials, in particular to a magnesium particle polymer composite material and a preparation method thereof, in particular to a composite material formed by distributing magnesium alloy particles in a polymer matrix. 2. Background technology Existing technology: Special functional plastics are developing rapidly. Mixing metals into plastics can strengthen plastics and improve other physical properties of plastics, such as endowing plastics with electrical conductivity, thermal conductivity, and shielding properties. 200310111401.1 discloses a magnesium-plastic composite material preparation process. First, the foamed magnesium material is made into a three-dimensionally connected prefabricated part with a pore diameter of 1-5mm, and then it is placed in a mold, kept at 150-350°C, and vacuumized. Composite mater...
