Abstract

A disclosed fireproof long-acting sealant is prepared from the following raw materials in parts by weight: 20-30 parts of butyl rubber, 15-25 parts of polyisobutylene, 17-21 parts of liquid polybutene, 7-10 parts of ebonite, 15-25 parts of triaryl phosphate, 13-16 parts of nanometer calcium carbonate, 18-24 parts of magnesium hydroxide, 3-6 parts of barium sulfate, 15-18 parts of aluminium hydroxide, 10-20 parts of rutile titanium dioxide, 7-14 parts of a phosphate fire retardant, 6-9 parts of diatomite and 12-16 parts of polyisobutylene. The provided fireproof long-acting sealant is good in sealing property, air impermeability, water sealing property, flexibility, beneficial for construction and installation, resistant to high and low temperature, and good in fireproof effect.

Description

technical field [0001] The invention relates to the technical field of building fireproof materials, in particular to a long-term fireproof sealant. Background technique [0002] Sealants are mainly used for bonding various objects or filling gaps, and their functions are mainly reflected in the two aspects of bonding and sealing. Due to the rapid development of various industries, the application fields of sealants are constantly expanding. In some occasions, sealants are required not only to have the functions of bonding and sealing, but also to have functions such as fire prevention and flame retardancy. There are a large number of construction pipes in the building, such as water pipes, power pipes, etc., passing through the holes and gaps formed in the walls and floors, which are all ways for fire to spread. Flame and smoke can easily spread to adjacent spaces through these holes and gaps. Increased fire damage. At present, there are some fireproof products made of ma...
