Abstract

The invention discloses a nanocage metal high-temperature anticorrosion thermal insulation material and belongs to the technical field of thermal insulation materials. The thermal insulation material is prepared from ceramic fiber, glass beads, montmorillonite powder, chrysotile, anionic surfactant, binder, viscosity regulator and water according to a certain weight ratio. The thermal insulation material has excellent flame retardance and water resistance, a finished product does not deform or crack after being soaked in water for 24 h, mechanical strength is high, the tensile strength and bonding strength of the material are extremely high, the thermal insulation property of a thermal insulator can be guaranteed without external support, service life is long, and the thermal insulation material can be widely used in chemical engineering, metallurgy, textile, building, medicine, petroleum, electricity, kiln, boiler and other industries as an insulating layer material.

Description

technical field [0001] The invention relates to a nano-cage metal high-temperature anti-corrosion and heat-preservation material made of nano-materials, and belongs to the technical field of heat-preservation and energy-saving materials. Background technique [0002] The traditional thermal insulation materials are mainly to increase the gas phase void ratio and reduce the thermal conductivity and conductivity coefficient. The insulation materials are mainly rock wool, slag wool, aluminum silicate wool and glass wool, and then supplemented with a metal protective layer to form an insulation system. The principle of heat preservation is to use air as a poor conductor of heat. The more fluffy the fiber filling, the more air can be stored in the space of the filling to the greatest extent. The size of the pores formed by the interaction of fibers and the level of porosity directly affect The insulation performance of the product. The fluffy fiber filling causes the low mechan...
