Abstract
The present invention provides a method for making a foamed aluminium heat-insulating material, and relates to a method for making a heat-insulating material. The method comprises the following steps: in the first step, metal aluminium powder of which the fineness is 800 meshes is chosen to be mixed evenly with CaCO3 in the mass ratio of 1: 0.03 to 0.035; in the second step, the mixture is heated to 1370 DEG C without oxygen, then heat preservation is performed for 10 minutes, and finally the temperature is lowered to 500 DEG C rapidly at the speed of 30 DEG C per minute; in the last step, the material of which the temperature is lowered to 500 DEG C continues to get cooled down to room temperature to become the foamed aluminium heat-insulating material, wherein the aluminium powder is industrial aluminium powder of which the fineness is 800 meshes and the purity is above 97 percent, and the CaCO3 is analytically pure CaCO3 powder. The foamed aluminium heat-insulating material can be used as a common heat insulating material, and can also be applied to special work environments, such as environments with high temperature and high humidity; the foamed aluminium heat-insulating material is good in flexibility and in heat insulating effect, and has the characteristics of high weathering resistance and high durability.
Description
Technical field
The present invention relates to a kind of making method of lagging material, particularly relate to a kind of making method of foamed aluminium heat insulation material.
Background technology
Lagging material commonly used at present mainly contains two big classes: the first kind is the inorganic heat insulation material of pearlstone and thermal insulation mortar class; Second class is that EPS is organic foaming insulation board of representative.Wherein the inorganic heat insulation material of the first kind absorbs water easily, and suction back heat-insulating property seriously descends; Though organic foaming insulation board of second class is difficult for suction, easily aging under the Working environment of high temperature, Exposure to Sunlight, long-term heat-insulating property can seriously descend.For some special Working environments, for example high temperature, high humidity environment must be used the lagging material of a kind of high-weatherability, high-durability.At present such lagging material does not also have other kind except multicellular glass, but multicellular glass is hard brittle material, and flexible difference and be difficult to processing also has certain limitation for the insulation of nonplanar objects such as pipeline.
Summary of the invention
The objective of the invention is to overcome the shortcoming of existing lagging material weathering resistance, poor durability and the flexible difference of multicellular glass, improve by test, providing a kind of is raw material with the metallic aluminium, with CaCO
3Be whipping agent, the making method of high insulating effect, high-weatherability, high-durability, flexible good lagging material.
The objective of the invention is to be achieved through the following technical solutions:
A kind of making method of foamed aluminium heat insulation material, its making processes is: select earlier fineness in 800 purpose metallic aluminium powders and fineness at the Powdered CaCO of 800 purposes
31: 0.03～0.035 uniform mixing of pressing mass ratio; Then the mixture starvation is heated to 1370 ℃, is incubated 10 minutes, be cooled to 500 ℃ rapidly with the speed of 30 ℃ of per minute kinds; The material that will be cooled to 500 ℃ again continues to be cooled to room temperature, is foamed aluminium heat insulation material.
Described metallic aluminium powder be fineness in 800 purpose purity at the industrial aluminium powder more than 97%, CaCO
3Be analytical pure CaCO
