Preparation method.
Background technique
Building thermal insulation material just plays on building heat preservation to be created suitable indoor thermal environment and energy saving has important work
With this kind of material reduces Indoor environment heat and distribute to outdoor, to keep by taking measures to building external envelope structure
Architecture indoor temperature.Mainly there are inorganic heat insulation material and organic insulation material two major classes in the thermal insulation material of China's Application in Building.
Inorganic thermal insulation material thermal coefficient is larger, and heat insulation effect is poor, by the fractional energy savings of existing country supervisor industry relevant regulations, protects
The thickness of adiabator must increase, and because its bulk density is also larger, not only increase built-loading, at the same also to construction bring it is many not
Just；In comparison, organic insulation material thermal coefficient is smaller, and heat insulation effect is preferable, while having lightweight, high-strength and construction party
Just the features such as, but the fatal defects that organic insulation material can not overcome there are two, first is that it is inflammable, second is that non-refractory, high
The lower easily carbonization of temperature loses thermal insulation property.The Ministry of Public Security expressly provided and forbade B grades of heat preservation plate materials in external wall in March, 2011
Using, it is desirable that the building exterior wall heat preserving in China uses A grades of incombustible materials, and organic insulation material is not achieved A grade standard, limits
Its application in building heat preservation field.Inorganic thermal insulation material is although can reach A grades of fire-fighting requirements, existing inorganic heat preservation
