Nano flame retardant and thermal insulating insulation material

Abstract

Disclosed is a nano flame retardant and thermal insulating insulation material. The material incudes a core nano composite thermal insulating material and a surface strengthening protective layer. Thenano composite thermal insulating material is a multilayer composite material based on a nano-balloon reflective layer. The surface strengthening protective layer includes a high temperature surfaceand remaining protective surfaces except the high temperature surface. The high temperature surface is inorganic fiber cloth after flame retardance treatment. The remaining protective surfaces are inorganic fiber cloth after inorganic nanosol treatment. According to the invention, the inorganic fiber cloth is treated by nanosol, which greatly increases the strength of the surface protective layer.A composite structure of a core combines the advantages of thermal insulation performance and mechanical properties of a plurality of thermal insulating materials, has strong adaptability, and is suitable for a plurality of equipment and environments.

Description

technical field [0001] The invention belongs to the technical field of thermal insulation materials, and in particular relates to a nano flame-retardant thermal insulation material. Background technique [0002] With the development of society and economy, the pressure on urban traffic continues to increase. The construction of underground comprehensive pipe corridors has greatly alleviated the problem of traffic congestion, and also facilitated the maintenance and repair of municipal facilities such as electricity, communications, gas, water supply and drainage. In developed countries in Europe and the United States There are many successful application cases. [0003] The construction of underground comprehensive pipe gallery is an important infrastructure and "lifeline" to ensure the operation of the city. The particularity of the underground pipe gallery environment puts forward many requirements for thermal insulation materials, such as the need to achieve efficient th...

Problems solved by technology

This invention has the advantages of compression resistance and cushioning, but the heat insulation effect and puncture resistance of a single air bubble are not ideal

[0007] Nano-insulation materials have excellent thermal insulation performance, but their structure also determines their weaknesses of low strength and poor integrity. The use of nano-materials and nano-airbag reflective layers, and the use of nano-sol to strengthen inorganic fibers is the optimal solution to solve the above problems.
