Abstract

The invention discloses an ammonium salt filled porous metal spontaneous perspiration composite material and a preparation method thereof. According to the prepared composite material, the ammonium salt accounts for 4.86%-48.8% by volume, the porous metal matrix accounts for 51.2%-95.14% by volume, pores of the porous metal matrix are evenly filled with the ammonium salt, and a good spontaneous perspiration cooling effect is achieved. Meanwhile, the composite material is prepared by adopting three methods, namely a repeated negative pressure impregnation method, a recrystallization method and a recrystallization and repeated negative pressure impregnation combined method.

Description

technical field [0001] The invention belongs to the technical field of preparation of spontaneous perspiration cooling composite materials, in particular to an ammonium salt filled porous metal spontaneous perspiration composite material and a preparation method thereof. Background technique [0002] Spontaneous perspiration cooling composite material is to fill the cooling medium into the porous matrix. When the material is heated, the cooling medium in the composite material undergoes phase change or decomposition, and then absorbs a large amount of heat to achieve the purpose of cooling the matrix. As far as the currently applied spontaneous perspiration cooling composite materials are concerned, the spontaneous perspiration cooling composite materials based on refractory metals have problems such as high density and low temperature brittleness, while the spontaneous perspiration cooling composite materials based on inorganic non-metallic materials are also brittle. Probl...
