Preparation method of three-dimensional melt-blown metal composite material

Abstract

The invention is applicable to the field of materials, and provides a preparation method of a three-dimensional melt-blown metal composite material. The preparation method comprises the following steps: performing melt-blown operation on a metal substrate; attaching metal particles to the substrate through a vacuum construction method, and covering uniformly; thickening the substrate in an electroplating mode; and mutually pressing a plurality of wires. According to the preparation method of the three-dimensional melt-blown metal composite material provided by the embodiment of the invention, the melt-blown technology has the advantages that the technological process is short, the attachment surface area of the metal to the substrate can be greatly increased, and attachment of traditional copper and nickel foil paper is replaced; the product can be used as an electromagnetic compatibility shielding material, and has the advantages of high conductivity, ultra-thin thickness of 14 microns, high temperature resistance of 340 DEG C, flame retardance, high tensile strength, integrated melt-blown spinning, no burr and smoothness, and no such product exists in the current market; and the existing substrate, new material and new process are replaced, and the cost is low. The product is 14 microns, is ultra-light, is 4 g per square meter, is high-temperature-resistant and can bear the high temperature of 340 DEG C.

Description

technical field [0001] The invention belongs to the field of materials, and in particular relates to a preparation method of a three-dimensional melt-blown metal composite material. Background technique [0002] Composite material is a new material formed by optimizing the combination of material components with different properties by using advanced material preparation technology. Generally defined composite materials need to meet the following conditions: Composite materials must be man-made, materials that people design and manufacture according to needs; Composite materials must be composed of two or more materials with different chemical and physical properties. Form, proportion, and distribution are combined, and there are obvious interfaces between components; it has structural designability, and composite structure design can be carried out; composite materials not only maintain the advantages of the material properties of each component, but also pass through each ...
