Abstract

The invention discloses a novel thermal-insulation metal material and a preparation method thereof. The novel thermal-insulation metal material comprises a first thermal-insulation layer, a second thermal-insulation layer and a metal material layer bonded between the first thermal-insulation layer and the second thermal-insulation layer, wherein the first thermal-insulation layer is an aluminum plated polyester film, and the second thermal-insulation layer is asbestos fiber. All elements added into the metal material layer are as follows in parts by weight: 30 to 40 parts of Al, 6 to 10 parts of Cu, 2 to 4 parts of Fe, 2 to 6 parts of Ti, 1 to 3 parts of Cr, 1 to 5 parts of Ni, 1 to 3 parts of C, 1 to 2 parts of Mo and unavoidable impurities. According to the novel thermal-insulation metal material, the metal material layer is wrapped by the first thermal-insulation layer and the second thermal-insulation layer; thus, a high temperature can be insulated completely, and the novel thermal-insulation metal material is good in thermal-insulation performance. Furthermore, the novel thermal-insulation material is simple in preparation technology and low in cost, and the thermal-insulation performance of the metal material is further improved by warming and heating the main metal raw materials before fusion and pouring.

Description

technical field [0001] The invention relates to a novel heat-insulating metal material and a preparation method thereof. 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. [0003] There are many kinds of thermal insulation materials, which can be divided into organic thermal insulation materials, inorganic thermal insulation materials and metal thermal insulation materials according to their materials. The thermal insulation materials used for thermal equipment and pipelines are mostly inorganic thermal insulation materials. This type of material has the characteristics of non-rot, non-combustible, and high-temperature resistance; organic heat-insulating ma...
