Curtain wall decorative finish vacuum heat insulation board and preparation method

Abstract

The invention discloses a curtain wall decorative finish vacuum heat insulation board and belongs to the technical field of building external wall materials. A board body of the curtain wall decorative finish vacuum heat insulation board is composed of a connecting layer, a resistor bridge layer, a vacuum heat insulation layer, an anti-cracking layer and a curtain wall decorative finish layer from inner surface to the outer surface, nanometer perlite, vacuum glass micro beads and other auxiliary materials are prepared into different slurries, and the curtain wall decorative finish vacuum heat insulation board is manufactured through forming, curing, edge trimming, steaming, drying steps and the like. The curtain wall decorative finish vacuum heat insulation board has the advantages of being low in dry surface appearance density, low in heat conductivity coefficient, high in compressive strength and high in burning resistant performance class, has a fire-proof function and further has the advantages of being light in weight, heat-insulation, high in size stability, anti-aging, anti-freezing, convenient to install, simple in construction, attractive in appearance and the like. Raising dust pollution caused by powder usage is reduced in the construction process, construction time is saved by 60% in construction period, construction cost is greatly reduced, and energy saving in building construction is really achieved.

Description

technical field [0001] The invention relates to the technical field of building exterior walls, in particular to a curtain wall facing vacuum heat insulation board capable of achieving heat insulation effect and a preparation method thereof. Background technique [0002] In my country, building energy consumption has become one of the three major energy consumers together with industrial energy consumption and transportation energy consumption. The energy-saving potential is huge. The building energy-saving industry has become an important organic part of the energy-saving and environmental protection industry. Building energy conservation is mainly accomplished through two aspects, one is to reduce building energy consumption, and the other is to improve the energy utilization efficiency of building energy consumption systems. The use of thermal insulation building materials is the main way to achieve building energy conservation. [0003] In the building energy-saving sys...

Problems solved by technology

In the current thermal insulation market, most of the inorganic thermal insulation materials whose fire protection level can meet the national requirements and local standards are slurry, and the thickness is difficult to control during the construction process, the quality is difficult to guarantee, and the performance cannot meet the final requirements.

Although the fireproof performance of inorganic thermal insulation materials can be guaranteed, their defects such as high density, low strength, and poor water resistance limit their application fields.
