External protection type nanometer air bag reflecting layer

Abstract

Disclosed is an external protection type nanometer air bag reflecting layer. The external protection type nanometer air bag reflecting layer consists of a reflecting layer A, a thermal insulation airbag layer B and a surface strengthening protective layer C. The A, B and C are superposed in order. The reflecting layer A is high-reflection mirror aluminum foil reinforced by a nanometer silicone coating. The thermal insulation air bag layer B is a polyethylene air bag layer superimposed by multiple layers. The surface strengthening protective layer C is inorganic fiber cloth impregnated by nanometer sol. According to the invention, the inorganic fiber cloth is treated by nanometer sol, which greatly increases the strength of the surface protective layer. A composite structure combines the advantages of good thermal insulation performance and excellent mechanical properties, 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 an outer protective nano-airbag reflective layer. 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 ther...

[0004] The Chinese patent with the publication number CN205935253U introduces a heat-insulating nano-airbag reflective layer, which includes an airbag heat-insulating layer. The upper and lower ends of the airbag heat-insulated layer are bonded with aluminum foil reflective layers. Layer, the outer wall of the aluminum foil layer is sprayed with a high-pressure polyethylene protective film. The heat-insulating nano-airbag reflective layer has good heat insulation, heat preservation, and reflective performance. It is light in weight and easy to lay, but the surface lacks a high-strength protective layer. , in actual use, it is necessary to lay additional
