Abstract

The invention provides a microporous heat insulation board with a high anti-radiation rate and a low heat conductivity coefficient and a preparation method thereof. The microporous heat insulation board takes white carbon black, an infrared light-screening agent and expanded vermiculite as main heat insulation materials, wherein added inorganic reinforced fibers are taken as a reinforcing material, pressure-sensitive adhesive is taken as a main binding material, high temperature-resistant glass fiber grid cloth as a reinforcing rib for a sandwich layer and a high-temperature radiant infrared energy-saving material is sprayed on the surface of the reinforcing rib; the microporous heat insulation board has excellent characteristics of ultralow thermal capacity, ultralow thermal conductivity, good flexibility, bendability, and easiness in constructing, cutting and processing.

Description

technical field [0001] The invention belongs to the technical field of heat insulation, and in particular relates to a microporous heat insulation board with high radiation reflection rate and low thermal conductivity and a preparation method thereof. Background technique [0002] In recent years, with the rapid development of nanotechnology, the traditional macroscopic heat transfer has been impacted, and an emerging technical field of microscopic heat transfer has been formed internationally. The research on the theory and application of micro-nano scale heat transfer has been actively carried out to provide new thermal insulation materials. Materials and energy-saving and consumption-reducing technologies have opened up a new way. Microporous insulation board is far ahead among various materials with its extremely low thermal conductivity and stable performance. Compared with traditional thermal insulation panels, microporous thermal insulation panels have ultra-low heat...
