Embodiment
[0014] Embodiment: The multi-layer aluminum silicate ceramic fiber blanket is sawn into fire-resistant belts for building insulation with a density of 80-96kg / m3, a length of 5000-7200mm, a width of 30-100mm and a thickness of 12.5-25mm. The thickness can be selected from 12.5mm and 25mm, and the thickness is uniform. The actual thickness can be combined arbitrarily according to the actual situation. The density is 80-96kg / m3, good thermal insulation performance, and the low density also reduces the cost. It can meet the requirements of heat insulation and fire insulation at a temperature of 1260 degrees for a long time, and its fire resistance temperature is as high as 1700 degrees.

The invention discloses a fire resistant belt for construction heat insulation, which is characterized in that the fire resistant belt for the construction heat insulation is made of an aluminium silicate ceramic fibre material. The fire resistant belt disclosed by the invention is thin in thickness, light in weight and easy to compress. The fire resistant belt can be filled in a gap between a pipeline and a building, such as a circuit to be packaged, a gas pipe and the like, therefore, external heat can be effectively insulated; and larger disasters when a fire happens can be reduced.
Description
technical field [0001] The invention relates to a fire-resistant belt for building heat preservation. Background technique [0002] With the construction of the city, more and more buildings are developed to high-rise buildings. In the event of a fire, fire trucks can no longer rescue buildings that are more than 100 meters high, and can only rely on improving the building itself to save itself (such as automatic fire alarms, automatic sprinklers, and manual use of fire hydrants). Building fireproof materials can slow down the spread of fire, buy time for people to escape, and minimize the loss of life and property. [0003] The building insulation materials currently used are basically flame retardant. Basically, flame retardants are added to the materials, but it is still possible to burn, and toxic and harmful components will be released during the burning process. If non-combustible materials are used, there are mainly two types at present. One is rock wool, although ...
