Flame-retardant curtain wall insulation board

Abstract

The invention discloses a flame-retardant curtain wall insulation board which comprises a board body and a board face. The board body is square, a square groove is formed in the back face of the board face, the board body is arranged in the groove in the back face of the board face, and the board body and the board face are made of a hard polyurethane foam material. A flame-retardant layer is arranged on the surface of the board face, a fire retardant layer is arranged in the board face, and the area of the fire retardant layer is larger than the surface area of the board body. A strengthened insulation layer is arranged in the board body and formed by arranging an insulation material in the middle of a cube metal box in a vacuumized mode, the board face and the back face of the board body are provided with sawtooth-shaped anti-falling grooves, and the board body and the board face are integrally formed. The insulation board is firm in bonding, not likely to peel off, good in insulation performance and flame-retardant performance and long in service life.

Description

technical field [0001] The invention belongs to the technical field of thermal insulation boards, and in particular relates to a flame-retardant curtain wall thermal insulation board. Background technique [0002] With the improvement of living standards, people pay more and more attention to the function of building energy saving and heat preservation. The heat preservation layer of the existing heat preservation board achieves the heat preservation function by adding organic heat preservation materials, but in the actual use process, this kind of heat preservation board or heat preservation Poor performance, or the frame itself is thin, low strength, easy to fall, poor flame retardancy, and short service life. After a certain period of use, new insulation boards need to be replaced in time to increase the insulation of the insulation boards in the building's exterior walls Performance and safety performance, which not only increases the workload of workers, but also easily...

[0002] With the improvement of living standards, people pay more and more attention to the function of building energy saving and heat preservation. The heat preservation layer of the existing heat preservation board achieves the heat preservation function by adding organic heat preservation materials, but in the actual use process, this kind of heat preservation board or heat preservation Poor performance, or the frame itself is thin, low strength, easy to fall, poor flame retardancy, and short service life. After a certain period of use, new insulation boards need to be replaced in time to increase the insulation of the insulation boards in the building's exterior walls Performance and safety performance, which not only increases the workload of workers, but also easily causes environmental pollution and waste of resources
