HD-STP building outer wall ultra-thin vacuum insulated panel and construction process thereof

Abstract

The invention discloses an HD-STP building outer wall ultra-thin vacuum insulated panel which is formed by inorganic fiber core materials and a high-resistance composite membrane. The high-resistance composite membrane is formed by compounding inorganic fiber cloth, aluminum foil and multiple layers of compact materials, and the core materials are formed by combining microporous inorganic materials and multiple kinds of additives. The HD-STP building outer wall ultra-thin vacuum insulated panel has the advantages of being formed by treating and packaging the inorganic fiber core materials and the high-resistance composite membrane through super-strong vacuum, being environmentally friendly and efficient and saving energy. High-efficiency heat insulation is achieved. The heat conductivity coefficient can be lowered to a large extent and is smaller than 0.04w / (m2.k). The excellent performance of being low in heat conductivity, ultrathin, light, resistant to corrosion, resistant to fire, non-combustible, environmentally friendly and good in sound absorption performance is achieved.

Description

technical field [0001] The invention belongs to the field of building heat preservation, and in particular relates to an HD-STP ultra-thin vacuum heat insulation panel for building exterior walls and a construction process thereof. Background technique [0002] At present, the world is facing an energy crisis, and energy conservation and emission reduction have become the focus of worldwide attention. The development of new energy, new technologies and new materials is imperative. As a new type of thermal insulation material, vacuum insulation panels have low thermal conductivity and thin thickness. Therefore, vacuum insulation panels have great development potential for reducing energy consumption and improving economy in construction and other fields. [0003] In the vacuum insulation panel, the selection of its core material is very important. In addition to being a supporting material, it can also limit the movement space of some gas molecules in the residual vacuum ins...
