Abstract

The invention discloses a thermal insulation metal composite, and relates to the technical field of metal materials. The thermal insulation metal composite comprises a metal composite layer and a thermal insulation layer; the metal composite layer is prepared from 20-30 parts of Al, 10-20 parts Ni, 20-30 parts of TiC, 5-10 parts of W, 3-5 parts of Cr, 2-5 parts of Co, 5-10 parts of Cu, 10-15 partsof Fe, 1-2 parts of Mo, 3-5 parts of NiCr and 1-3 parts of Cr3C2. The thermal insulation layer is a glass fiber material layer and a polyimide layer, and the glass fiber material is arranged betweenthe polyimide layer and the metal composite layer. The thermal insulation metal composite has the advantages that by arranging the thermal insulation layer, comprehensive isolation of high temperaturecan be achieved, the good thermal insulation performance, durability and non-stickiness are achieved, the high-temperature materials are not adhered, and the strength, tenacity and corrosion resistance of the composite are greatly improved.

Description

technical field [0001] The invention relates to the technical field of metal materials, in particular to a heat-insulating metal composite material. Background technique [0002] Metal materials are usually made of 100% metal components. Products made of such metal materials have been widely used and promoted in the market, but they are easily affected by external factors and rusted, and in some specific The environment often cannot meet people's use needs, such as the heat insulation performance of metal materials. At present, heat insulation materials can be divided into three categories according to their materials: organic heat insulation materials, inorganic heat insulation materials and metal heat insulation materials. The heat insulation materials used for thermal equipment and pipelines are mostly inorganic heat insulation materials. This type of material has the characteristics of non-rot, non-combustible, and high temperature resistance, such as: asbestos, diatoma...
