Abstract

The present invention discloses the preparation process of thin layer tunnel fire-proof paint of expandable graphite-glue powder system. The paint consists of dispersible latex powder 40-50 weight portions, expandable graphite 30-50 weight portions, aluminum hydroxide 5 weight portions, magnesium hydroxide 10-15 weight portions and water-proof powder 5-10 weight portions. The paint has dispersible latex powder as adhesive and expandable graphite as fire-proof and smoke isolating material, so that it has high coating adhesion strength, short coating curing period, high construction efficiency, high fire tolerance limit of the coating and high environment friendship. In addition, the paint is dry powder product and is used after adding water in the site, and this facilitates the packing, transportation and use.

Description

technical field [0001] The invention belongs to the technical field of inorganic non-metallic materials and fire protection, and relates to a method for manufacturing an expandable graphite-rubber powder system thin coating environment-friendly tunnel fireproof coating. Background technique [0002] With the development of society, a large number of road tunnels and railway tunnels have appeared in the circulation of materials and interpersonal communication between cities. Tunnels are the throats of traffic. Some tunnels not only undertake the task of transportation, but also function as fiber optic cables, power cables and even water transportation channels. Tunnel fire hazards are high, and tunnel fire prevention is very important. Due to the complex structures of tunnels and subway buildings, the airtight environment, and the dense population, once a fire breaks out in the limited tunnel space, it is very difficult to extinguish it, often causing heavy casualties and p...
