Thermal insulation material and preparation method thereof
The invention provides a thermal insulation material and a preparation method thereof. An exhaust component is pre-buried in core material powder and extends to the surface layer of the core material powder, the exhaust component is subjected to compression molding through a compression mold along with the core material powder, and the compression molding further comprises a normal-temperature pre-pressing stage and a heating compression molding stage; the exhaust component is a hollow part, a plurality of through holes are formed in the surface of the exhaust component, and a cavity in the hollow part further communicates with the outside through the through holes. The heat insulation material is prepared through integral compression molding, hot press molding is carried out after compression molding at normal temperature, and the cohesiveness between the exhaust component and powder can be improved, so that the whole core material forms a more compact structure. According to the thermal insulation material and the preparation method thereof, air in the powder in the powder pressing process can be exhausted, and a compact core material is prepared.
本发明提供了一种隔热保温材料及其制备方法，排气部件预埋于芯材粉末的内部并延伸至芯材粉末的表层，所述排气部件随芯材粉末通过压制模具进行压制成型，压制成型还包括常温的预压阶段和升温的压制成型阶段；所述排气部件为中空件，排气部件的表面设有若干通孔，中空件内部的空腔还通过所述通孔与外部相连通。隔热保温材料通过一体压制成型制备，常温下压制成型后进行热压成型，排气部件可以增加与粉体之间的粘结性，使得整个芯材形成更加密实的结构。本发明能够排出粉体压制过程中粉体内部的空气，制备密实的芯材。
