preparation example Construction

[0033] The invention relates to a composite material of amorphous metal and plastic, and also relates to a composite shell made of the composite material of amorphous metal and plastic and a preparation method thereof. Composite materials not only have the corrosion resistance, wear resistance, electromagnetic radiation resistance and good external sensory properties of amorphous metals, but also have the characteristics of light weight of plastics. At the same time, because the amorphous metal layer is very thin, the entire composite material The cost is quite low.

[0034] The amorphous metal includes one or more of zirconium-based, iron-based, copper-based, nickel-based and cobalt-based amorphous metals.

[0035] Preferably, the amorphous metal is zirconium-based or / and iron-based amorphous metal.

[0036] The plastics include one or more combinations of PA, PC, PET, PP and ABS.

[0037] Preferably, said plastic is polycarbonate and acrylonitrile-butadiene-styrene copolym...

Abstract

The invention relates to a composite material of amorphous metal and plastics, a composite shell and a preparation method of the composite material, belonging to the technical field of macromolecule engineering materials. The composite material comprises an amorphous metal layer and a plastic layer adhered with the amorphous metal layer together, wherein the thickness of the amorphous metal layer is from 5 to 150mu m, and the thickness of the plastic layer is from 0.2 to 6 mm. The composite material is prepared by adopting the preparation method comprising the following steps of: (1) adhering an amorphous metal sheet to the inner wall of an injection mould chamber, (2) injecting molten plastic into an injection port of the injection mould chamber, cooling and forming so that the amorphous metal layer and the plastic layer are adhered together to form an entire body. Through compositing plastic on the amorphous metal sheet, the composite material has the advantages of corrosion resistance, wear-resisting property, electromagnetic radiation prevention property and favorable external sensitive property of amorphous metal, and also has the characteristic of plastic, such as light weight. Meanwhile, because the amorphous metal layer is very thin, the cost of the entire composite material is rather low.

Description

【Technical field】 [0001] The invention belongs to the technical field of polymer engineering materials, and relates to a composite material of amorphous metal and plastic, a composite shell and a preparation method thereof. 【Background technique】 [0002] Amorphous metals are metals in which atoms are arranged in three-dimensional space without long-range order. Compared with crystalline metals, amorphous metals undergo significant changes in physical, chemical, and mechanical properties. Amorphous metals have high dislocation density, uniform macrostructure, and no defects such as grain boundaries, which are considered to be the main reasons for high toughness and high strength. [0003] From a structural point of view, amorphous metals have no defects such as grain boundaries and stacking faults, no segregation, precipitation, and heterogeneous phases. When appropriate elements are added to form a metastable state, they will show amazing corrosion resistance. Alkaline or...
