Abstract

The invention discloses an intumescent flame-retardant belt material for buildings and belongs to the field of building fire protection devices. The intumescent flame-retardant belt material applies to pipeline fire protection and comprises an intumescent flame-retardant belt, wherein the outer surface of the intumescent flame-retardant belt is coated with a casing, a support frame is mounted on the outer surface of the casing, a hoop is mounted outside the support frame, and clamp plates are distributed on upper and lower end surfaces of the hoop and make contact with end surfaces of the intumescent flame-retardant belt, the casing, the support frame and the hoop; the support frame is formed by inverted V structures uniformly distributed around the outer surface of the casing, and gaps are formed between adjacent inverted V structures and in internal spaces of the inverted V structures; a plurality of auxiliary intumescent holes are formed in the intumescent flame-retardant belt, andheat conducting bars are mounted in the auxiliary intumescent holes. The novel foam type flame-retardant belt material for the buildings is high in flame retardant efficiency, intumescent efficiency,intumescent capacity and self-stability, quite high in size adaptability, highly water-resistant and cement-resistant.

Description

technical field [0001] The invention belongs to the field of building fireproofing devices, and in particular relates to an intumescent fire-retardant strip for building and an intumescent fire-retardant strip applied to the strip. Background technique [0002] With the acceleration of the urbanization process, the number and height of buildings in the city gradually increase, and the situation of building fires also occurs from time to time. During the investigation of a fire in a building, it was found that one of the conditions that contributed to the spread of the fire in the building was the plumbing in the building. [0003] Plastic pipes are widely used in various public and civil constructions, especially PVC-U-shaped pipes with excellent performance, which have a very high utilization rate, but plastic pipes often become the channel for fire spread rashly, and the holes formed after the plastic pipes are burnt by heat are like A chimney that allows the flame and sm...
