Description
Technical Field
The utility model belongs to the technical field of the building insulation material technique and specifically relates to a aerogel rock wool composite insulation board is related to.
Background
At present, the energy-saving requirement of China on the external thermal insulation system of the external wall is that the energy is saved by 75 percent or more, and the fireproof requirement of China on the external thermal insulation system of the external wall is that the A-level fireproof requirement is met. Building energy conservation is the need for realizing sustainable development, building fire prevention is the need for social safety, and the two must be considered at the same time, but the two are not enough. At present, the fire resistance and the heat insulation performance of the heat insulation material used by the external wall heat insulation system are compared, and because the safety is the first, the fire resistance of the external wall heat insulation material is paid more attention and meets the requirement, and the fire resistance of the external wall heat insulation material is required to meet the A-level fire resistance requirement.
Because the fireproof performance of the rock wool is good and can meet the A-level fireproof requirement, the rock wool is an inorganic heat-insulating material which is widely applied in an external wall heat-insulating system nowadays, but the heat-insulating performance of the rock wool is poorer than that of organic heat-insulating materials (such as EPS heat-insulating plates, XPS heat-insulating plates, polyurethane hard-foam heat-insulating plates and the like) which are commonly used nowadays, and the difference is larger.
Aerogel is a low-density material with a nano-scale porous structure, and is also commonly referred to as solid smoke due to its extremely low density and light weight; meanwhile, since 95% or more of aerogel is air, it has excellent heat insulation effect, and for example, thermal conductivity of silica aerogel at room temperature can be as low as 0.013W/(m · K), so aerogel is considered as the thermal insulation material with the best thermal insulation performance. However, pure aerogel has poor strength and is difficult to be used as a block material alone for heat insulation engineering or other fields, and aerogel and fiber materials are usually compounded to form a composite material to meet the use requirements.
Therefore, how to design a composite insulation board for heat preservation system outside outer wall, this composite insulation board can make full use of the A level fire behavior of rock wool, and can solve the relatively poor problem of heat insulating ability of rock wool, again can make full use of the good heat insulating ability of aerogel for this aerogel rock wool composite insulation board both has A level fire behavior, has good heat insulating ability again, is the technical problem that technical staff in the field needs to solve at present urgently.
