Abstract

Aiming at the problems in the prior art that the silica aerogel is high in price and the heat conductivity coefficient of an ordinary thermal insulation material is large, the invention particularly relates to a carbon aerogel thermal insulation material and a preparation method thereof. The carbon aerogel thermal insulation material consists of the following components in parts by weight: 100 parts of a man-made inorganic fiber, 0-200 parts of a carbon material, 0.5-2.0 parts of a dispersing agent and 0.5-2.0 parts of an adhering agent. The carbon aerogel thermal insulation material provided by the invention can be a powder material, a slurry material, a felt material or a plate material in state. The carbon aerogel thermal insulation material has the advantages of small heat conductivity coefficient and moderate price, is easy to construct and popularize, and can be widely applied to insulation of buildings, industrial equipment and pipelines; and the preparation method is low in cost and simple and easy to operate.

Description

technical field [0001] The invention belongs to the field of thermal insulation materials, in particular to a carbon airgel thermal insulation material and a preparation method thereof. [0002] Background technique [0003] In the 1990s, the researchers of the National Aeronautics and Space Administration (NASA) developed and adopted a new space thermal insulation reflective porcelain layer (Therma-Cover) to solve the problem of heat transfer control of aerospace vehicles. Composed of tiny ceramic particles in latex, it has thermal properties such as high reflectivity, high emissivity, low thermal conductivity, low heat storage coefficient, etc., and has excellent heat insulation reflection function. This high-tech material has been popularized and applied to civilians in the aerospace field abroad, used in construction and industrial facilities, and has been exported to my country for use in some large-scale industrial facilities. But the fly in the ointment is that the ...
