Composite thermal insulation board with circulation channel dual-cavity structure

Abstract

The invention relates to a composite thermal insulation board with a circulation channel dual-cavity structure and relates to the technical field of composite materials. A matrix of the composite thermal insulation board is a composite thermal insulation material layer which is installed outside a cement face layer, the composite thermal insulation material layer is composed of an outer soft rock layer, a calcium silicate board layer, an anti-cold bridge block (extruded polystyrene) layer and an air bag structure layer, the calcium silicate board layer is adhered to the soft rock layer through adhesive mortar, the anti-cold bridge block (extruded polystyrene) layer is adhered to the calcium silicate board layer, and the air bag structure layer is adhered to the cement face layer. The composite thermal insulation board is characterized in that the outer portion of the air bag structure layer is provided with a thermal insulation strip which exerts a supporting function, an air bag which is formed by heat sealing of thin films is arranged in the thermal insulation strip, a hollow cavity ventilation structure which is a dual-layer hollow cavity is further arranged in the air bag, a first hollow cavity is in a seal state, the end of a second hollow cavity is provided with a plastic pipeline which is communicated with external space, and an intelligent hot air valve is arranged on one side of the plastic pipeline and installed at the connection position of the second hollow cavity and the plastic pipeline. The composite thermal insulation board is reasonable in structure, good in decorative effect, low in cost and good in thermal insulation performance.

Description

Technical field: [0001] The invention relates to the technical field of composite materials, in particular to a composite thermal insulation board with a double-cavity structure of circulation channels. Background technique: [0002] In today's construction industry, the thermal insulation effect of the building is very important, and the material of the thermal insulation board is very important. Generally, the thermal insulation board is made of polystyrene resin as raw material plus other raw materials and polymers. The rigid foam board is made by injecting the catalyst and then extruding it. Its scientific name is extruded polystyrene foam for thermal insulation. However, due to the different shrinkage of the composite material during the production process, the heat , drying deformation, so there will be many problems in production, and now generally use hard materials, such as benzene board, hollow brick, etc., and this material is complicated in construction, large in...

Problems solved by technology

However, the weakness of flexible tiles, soft porcelain, and artificial decorative panels is that they are deformed when heated and dried, and the materials are different when they are combined, the expression is monotonous, and the degree of simulation is poor.
