Detailed introduction

  The fire isolation belt is a part of the external wall thermal insulation system. A complete system is generally composed of wall, base layer, anchor bolt, adhesive, fire isolation belt, glass fiber mesh, and finishing layer from the inside to the outside. In this system, it is required that the insulation layer of the fire isolation belt must be the same thickness, so that the entire area can be pasted, and the anchor bolts must be pressed against the mesh cloth on the bottom layer.

  Up to now, the fire isolation belts used in buildings include: DY inorganic thermal insulation mortar, foam glass, rock wool, foamed ceramics, foamed cement and other A-level fireproof materials. DY inorganic thermal insulation mortar, cement foam fire isolation belt are inorganic materials, which can be widely used in fire isolation.

  External thermal insulation and fire prevention of external walls: In order to prevent the spread of fire, it is composed of A-grade non-combustible thermal insulation materials arranged between the combustible thermal insulation materials of the external thermal insulation system of the building. It has a certain design width and length and has no cavity bonding structure with the wall.

  Base layer: the external wall to which the external thermal insulation system of the external wall is attached.

  Insulation layer: It is composed of hydrophobic rock wool board and plays the role of thermal insulation in the external thermal insulation system.

  Surface layer: The surface layer is composed of surface mortar and fiberglass mesh cloth for reinforcement. It is applied on the rock wool insulation layer or leveling layer to protect the rock wool board and play the role of crack resistance, waterproof and impact resistance.

  The special fireproof isolation belt for rock wool board should be supplied together with the external wall thermal insulation system.

  The special fire isolation belt for rock wool board The external wall thermal insulation system should be reliably connected with the base wall, should be able to adapt to the normal deformation of the base without cracks or hollows, and should be able to withstand the long-term repeated action of self-weight, wind load and outdoor climate for a long time Without harmful deformation and damage, it should have waterproof permeability.

  The external wall thermal insulation system of the special fire isolation belt for rock wool board should have the ability to prevent the spread of fire, and the fire performance test results of the external wall external thermal insulation system should be used as the basic basis for judging whether the fire isolation belt is effective.

  The construction technical scheme of the special fireproof isolation belt for rock wool board external wall and external thermal insulation system shall include the construction technology of the fireproof isolation belt.

  The special fire isolation belt for rock wool board should have certain thermal insulation performance, and the thermal resistance of the fire isolation belt should not be less than 40% of the thermal resistance of the external wall insulation system.

  The combustion performance grade of the core material of the thermal insulation material of the external wall and external thermal insulation system should not be lower than B2 level, and the oxygen index should not be less than 26%; the combustion performance grade of the core material of the thermal insulation material of the fire isolation belt should be grade A.

  The special fireproof isolation belt for rock wool board should be installed on site by factory prefabricated products. Under the conditions of correct use and normal maintenance, the fire isolation belt should meet the service life requirements of the external wall thermal insulation system.
