Expansion type fireproofing glue strip for construction

Abstract

The invention discloses an intumescent fireproof adhesive tape used in construction and relates to the field of fireproof sealing materials, aiming at solving the technical problems that the existing fireproof sealing tape does not have good pliability under normal temperature, thus being inconvenient for construction and installation, and can not resist high-temperature thermal current when encountering fire, etc. The intumescent fireproof adhesive tape used in construction of the invention consists of the components by parts by weight (pbw) as follows: 10 pbw to 60 pbw of rubber, 10 pbw to 40 pbw of plastic, 10 pbw to 40 pbw of compounded material, 10 pbw to 30 pbw of intumescent material, 8 pbw to 55 pbw of flame retardant material, 0 pbw to 8 pbw of lubricating material and 0 pbw to 8 pbw of stabilizing material. The intumescent fireproof adhesive tape of the invention is applicable to the blocking of perfoliate openings and fireproof sealing of building apertures.

Description

technical field [0001] The invention relates to the field of fireproof sealing materials, in particular to an intumescent fireproof rubber strip for building fireproof sealing used for sealing penetrating openings and building gaps. Background technique [0002] During the construction of buildings, there are a large number of construction pipes crossing vertically and horizontally between floors and walls, such as air-conditioning pipes, smoke prevention pipes, water pipes, heating and power pipes, ventilation pipes, gas pipes, oil pipes and other process pipes Wait. These pipes pass through the holes formed by walls and floors, or the gaps between floors and walls, and walls and walls are all ways for fire to spread. In addition, in order to ensure the normal use of fire doors, fire windows, fire dampers and fire shutters in buildings, some gaps should also be reserved. If these holes or gaps are not effectively blocked, once a fire breaks out, these holes or gaps will f...

AI Technical Summary

Problems solved by technology

[0009] The invention aims to solve the technical problems that the existing fireproof sealing strip has no good flexibility at normal temperature and cannot resist high temperature hot air flow when it encounters a fire, so as to provide a kind with good flexibility at normal temperature, which is convenient for construction and installation, and can expand at high temperature. It is an intumescent fireproof adhesive strip for construction that is foamed and has a certain strength, can withstand the impact of jet fire or strong airflow, and can reliably seal building holes or gaps in building components
