Description

Technical field [0001] The invention belongs to the technical field of thermal insulation materials, and specifically relates to a high-strength thermal insulation pipe and a preparation method thereof. Background technique [0002] Lightweight bricks, refractory fibers, ceramic fiber blankets and other traditional thermal insulation materials have relatively high thermal conductivity, and cannot meet the energy-saving requirements of industrial equipment with a temperature of less than 70℃ under a given thickness. Therefore, thermal insulation materials with low thermal conductivity are more and more popular. People's favor. [0003] At present, there are two main types of insulation materials: one is vacuum insulation material, and the other is nanoporous insulation material. There are a large number of nano-pores in the structure of the nano-silicon thermal insulation material, and more than 85% of the pores are less than 50 nm in diameter. The mean free path of oxygen and nit...
