Problems solved by technology

At present, most of the core materials of thermal insulation boards are composed of diatomaceous earth and silicon dioxide. During the use as an exterior wall panel, when the outer vacuum bag is damaged, the core material is prone to deformation, which affects the use effect
[0005] In addition, since the core material cannot be integrated with the vacuum bag, the vacuum bag is prone to damage during construction and use, which affects the insulation effect and service life of the outer wall

Abstract

The invention discloses a vacuum inorganic insulation outer external wall board, a manufacturing method thereof and an external wall insulation system, and provides an external wall board with a low heat conductivity coefficient and a good insulation effect, and an insulation system consisting of external wall boards. The external wall board is made of a composite gas barrier film and a core material through a vacuum-pumping packaging technology, and the core material consists of silicate, silica fume, fumed silica and glass fibers. The external wall insulation system is constructed by fixedly connecting a plurality of vacuum inorganic insulation outer external wall board through a plurality of fixing pieces; the upper portion of an outer baffle plate of each fixing piece, a support plate and an inner baffle plate construct a U-shaped groove for supporting the joint of two vacuum inorganic insulation outer external wall boards positioned above, the lower inner walls of the outer baffle plates stick close to the outer surfaces of the vacuum inorganic insulation outer external wall boards positioned below, and bolts enter an external wall body by passing through the outer baffle plates, the joint of two vacuum inorganic insulation outer external wall boards and the inner baffle plate. Since the core material and the composite gas barrier film are inorganic materials, the external wall board has the advantages of low heat conductivity coefficient, good heat insulation effect, high durability and long service life.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a vacuum inorganic thermal insulation external wall panel and an external wall thermal insulation system composed of it, and a manufacturing method of the vacuum inorganic thermal insulation external wall panel. Background technique [0002] In order to reduce the energy consumption of buildings, thermal insulation boards are installed outside the exterior walls of buildings to meet the requirements of building thermal insulation and achieve the purpose of building energy conservation. [0003] With the development of exterior wall insulation technology, STP ultra-thin insulation panels have gradually become a hot spot in exterior wall insulation research. [0004] The current STP ultra-thin insulation panels are mainly composed of vacuum bags and internal core materials. The vacuum bags are mainly used to keep the interior of the insulation panels in a vacuum state, a...
