Outer wall vacuum inorganic foam insulation plate and manufacturing method thereof

Abstract

The invention relates to an outer wall vacuum inorganic foam insulation plate and a manufacturing method thereof. The insulation plate is made of a vacuum packaging bag and a foam insulation core plate mounted in the bag; the foam insulation core plate is one of a foam cement plate or a foam glass plate or a foam ceramic plate; the vacuum packaging bag adopts an aluminum foil vacuum packaging bag; construction mounting edges of 15-30 mm are pressed on the two sides or the periphery of the aluminum foil vacuum packaging bag; and the aluminum foil vacuum packaging bag adopts a single-layer aluminum foil vacuum packaging bag or a dual-layer aluminum foil vacuum packaging bag. Due to the insulation plate, the thickness of the outer wall insulation plate can be reduced, the thermal insulation and insulating performance of the insulation plate can be enhanced, the phenomenon of expanded deformation, aging, cracking, damage and the like can be also eliminated, and the service life of a wall body is greatly prolonged. The insulation plate has the advantages of light weight, low heat conducting coefficient, excellent insulation performance, high strength, aging resistance and good fireproofing flame retardant effect.

Description

technical field [0001] The invention belongs to the technical field of thermal insulation of building walls, and in particular relates to an external wall vacuum inorganic foam thermal insulation board and a preparation method thereof. Background technique [0002] Building energy conservation is an extremely important policy of the country, and it is a systematic project that benefits the country, the people, and future generations. Strengthening the thermal insulation of buildings plays a direct and practical role in improving people's working and living environment conditions and saving energy. With the development of my country's economy, the problem of energy shortages has become increasingly prominent, and building heating is costly and wasteful. become an important topic. The further standardization of the "standards" of civil building energy-saving design and the implementation of the State Council's "Regulations on Energy Conservation of Civil Buildings" put forward...

Problems solved by technology

For example: extruded board, polypropylene foam board, polystyrene board and polyurethane board, etc. The source of the base material of this foam insulation board is petrochemical products, which not only consumes a lot of energy, but also causes a shortage of raw material resources. Rather than energy saving, and the production process is complicated, the cost is high, and there are insurmountable natural defects: not resistant to high temperature, easy to burn, poor anti-aging, releasing toxic and harmful substances, etc.

In the energy-saving design of buildings, inorganic thermal insulation mortar is used as the main material for external wall insulation. requirements, but still cannot meet the 65% energy-saving standard proposed by the state, and in the external wall structure, due to the need for thermal insulation, the thickness of the thermal insulation layer is usually 6 cm, but in cold and severe regions, the thickness of the thermal insulation layer needs to be increased to 8 to 10 centimeters, or even more than 10 centimeters, can meet the functional requirements. In this way, not only the engineering quality of the insulation layer is difficult to guarantee, but also the construction process of the insulation layer is cumbersome, time-consuming, long construction period, high cost, and the quality depends entirely on people. The quality of the work is guaranteed, and it is a concealed project. It is not easy to check and find out that the work is rough during the construction process, or even cut corners, which leads to the loss of control of the construction quality and seriously affects the quality and service life of the wall insulation.
