Abstract

The invention relates to the field of metal alloy materials and specifically relates to a thermal insulation metal material. The thermal insulation metal material is prepared from a metal material anda thermal insulation material, wherein the metal material is prepared from the following chemical components in percentage by weight: 8-11% of Al, 6-10% of Mn, 6-11% of Y, 0.6-1.2% of Zn, 0.2-0.5% ofSi, 0.5-1% of Zr and the balance of Mg. A thermal insulation material strip penetrates through the middle of the metal material, and the metal material is cut to form a broken bridge. The preparationmethod of the thermal insulation metal material provided by the invention comprises the following steps: melting a magnesium alloy prepared from Mg, Al, Zn, Si and the like into liquid under protection of a solvent covering agent; adding Y, Zr and Mn and stirring; heating to 760-820 DEG C; injecting the liquid-state thermal insulation material into an alloy type thermal insulation slot, and solidifying; combining the two separate parts of the magnesium alloy by the thermal insulation material; finally, refining at 680-730 DEG C, and performing certain standing inoculation before casting moulding. The thermal insulation metal material has the functions of insulating heat and cold. Moreover, the thermal insulation metal material also has good thermal insulation property and sound insulationproperty.

Description

technical field [0001] The invention belongs to the field of metal alloy materials, and in particular relates to a heat-insulating metal material. Background technique [0002] Heat insulation metal is a new type of building material that meets the requirements of building energy conservation. It is a composite material with heat insulation and cold insulation functions made of low thermal conductivity non-metallic materials connected with alloy building profiles. In addition to its characteristics as a building profile, it also has excellent thermal insulation and sound insulation properties. [0003] The principle of heat-insulating metal is to penetrate heat-insulating strips in the middle of the metal. There are two main production methods for heat-insulating profiles. One is to use heat-insulating strip materials and metal materials, and through mechanical tooth opening, threading, rolling and other processes The formation of "insulation bridge" is called "strip type" ...
