Abstract

The invention discloses a nest type thermal insulation board and belongs to the technical field of building external wall materials. A board body of the board is constituted by an assembling layer, a resistor bridge layer, a thermal insulation layer, a crack resisting layer and a decoration layer in sequence from the bottom surface layer to the external surface layer, and a preparation method comprises the steps of fabricating materials such as expanded perlite, cement, glass fibers and other accessory materials into different slurry materials, making a structure provided with multiple cone-tower-shaped nests out of the bottom surface, then continuing with the steps of formation, curing, trimming, steam curing, drying and the like, and obtaining the nest type thermal insulation board. The nest type thermal insulation board has the advantages that the dry surface of the thermal insulation board is low in density, the thermal conductivity coefficient is low, the compressive strength is high, the combustion-resisting perform level is high, the board has the fireproof function, and the board has the advantages of being low in weight, heat preservative, high in dimension stability, aging resistant, frost resistant, convenient to install, simple to construct, beautiful in appearance and the like. In the construction process, the flowing dust pollution caused by application of powder materials is reduced, approximately 60% of construction time is saved in the construction cycle, the construction cost is greatly reduced, and the energy consumption is saved in the building construction in the real sense.

Description

technical field [0001] The invention relates to the technical field of building exterior walls, in particular to a nest-type thermal insulation board capable of preventing expansion and falling off 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 system, the h...
