Abstract

The invention provides a CNT (carbon nano tube) nano-particle composite insulating material and a preparation method thereof. The CNT nano-particle composite insulating material comprises CNTs, wherein a nano-particle layer is attached to the surface of each CNT and is a mixture A formed by diatomite nano-particles, attapulgite nano-particles and expanded perlite nano-particles, and the surface ofthe nano-particle layer is coated with a mixture B formed by phosphate, magnesium chloride, magnesium hydroxide, fiber, silicate, a high-temperature ceramic adhesive, white alum, portland blast furnace cement, fly ash and a foaming agent. The diatomite nano-particles, the attapulgite nano-particles and the expanded perlite nano-particles are attached to the surfaces of the CNTs according to the quite large specific surface area of the CNTs, and insulating effect and insulating persistence of the diatomite nano-particles, the attapulgite nano-particles and the expanded perlite nano-particles are improved.

Description

technical field [0001] The invention belongs to the technical field of thermal insulation materials, in particular to a preparation method of a carbon nanotube nanoparticle composite thermal insulation material. Background technique [0002] With the development of economy and society, the global demand for energy is also increasing day by day, the energy problem is becoming increasingly tense, and the issue of building energy conservation has attracted more and more countries' attention. Building energy conservation is the rational use and effective use of energy in buildings, continuous improvement of energy utilization efficiency, and reduction of building energy consumption. On the other hand, building energy conservation will also have a direct or indirect impact on environmental protection, improving the environment. Conventional carbon nanotube nanoparticle composite insulation materials used in construction are relatively single in composition, and most of them are ...
