Waterproof fireproofing inorganic plugging material

Abstract

The invention discloses a waterproof and fireproof inorganic blocking material which is prepared by mixing the following raw materials with the parts by weight: 40-56 parts of construction gypsum, 0-20 parts of grade I fly ash or grade II fly ash, 24-40 parts of fine mineral powder and common Portland cement, 0-1 part of methyl cellulose ether, 0-3 parts of calcium stearate or zinc stearate or the mixture thereof, 0-0.1 part of citric acid monohydrate, 0-300 parts of quartz sand, 0-75 parts of vitrified micro bead and 0-75 parts of expanded vermiculite. The waterproof and fireproof inorganic blocking material of the invention has the advantages of superior waterproof and fireproof performance, fast coagulating and hardening speed, quick increase in early strength, moderate later strength, convenient disassembly, simple construction, immediate use after being mixed, free adjustment of coagulating time, convenient storage and transportation, environmental protection, etc.

Description

technical field [0001] The invention relates to a waterproof and fireproof inorganic plugging material, in particular to a plugging material for flame retardant, fireproofing and waterproofing of power plants, power stations, cable trenches and cable tunnels, especially a waterproof and fireproof material for plugging penetrating openings. Background technique [0002] During the construction and use of the building, there are a large number of cable penetration holes, ventilation and air conditioning ducts, smoke prevention ducts, openings for heating ducts and building gaps between the floor and the wall. Once a fire breaks out, flames and toxic gases will spread to adjacent places through these openings and gaps. At the same time, pipelines such as cable channels may also form a shaft effect, which accelerates the expansion of the fire and increases the difficulty of fire fighting. Therefore, it is of great significance to block the openings and gaps and improve the fire ...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to solve the problems of slow setting and hardening, slow early strength growth and high later strength, which is not conducive to disassembly and poor fireproof performance of the traditional inorganic fireproof blockage mainly based on ordinary Portland cement. Excellent fireproof performance, fast setting and hardening, rapid early strength growth, moderate later strength, easy to dismantle, simple construction, ready-to-use, setting time can be adjusted freely waterproof and fire-proof inorganic sealing material
