Problems solved by technology

When a fire occurs in a tunnel, the temperature is generally above 1000°C. The masonry of the tunnel cannot withstand such a high temperature, and the serious part is easy to burn down. In addition, the tunnel environment is relatively airtight and the density of people is high. Once a fire occurs, evacuation and fighting are very difficult and easy. Cause heavy casualties and property losses, so it is very important to carry out fire prevention treatment for tunnels

Abstract

Belonging to the technical field of chemical industry, the invention discloses a novel tunnel fireproof paint. The fireproof paint is composed of the following components by weight: 22-38 parts of phosphate, 10-18 parts of gypsum, 15-24 parts of a chloroprene rubber emulsion, 3-8 parts of water-soluble glass fiber, 30-46 parts of magnesium hydroxide, 5-8 parts of alumina, 2-6 parts of ammonium borate, 10-14 parts of sepiolite, 25-29 parts of asbestos powder, 12-16 parts of expanded perlite, 10-11 parts of polyvinyl chloride, 3-8 parts of pentaerythritol, 3-6 parts of vermiculite, 1-4 parts ofammonium dichromate and 0.8-4 parts of a dispersant. The tunnel fireproof paint provided by the invention has the advantages of low bulk density, good fire resistance and heat insulation, water tolerance, acid and alkali resistance, etc., can prevent rapid temperature rise of steel concrete in tunnels so as to lower the temperature and avoid concrete cracking. The fireproof paint is suitable for flameproof protection of highway tunnels and railway tunnels.

Description

technical field [0001] The invention belongs to the technical field of chemical industry, in particular to a novel tunnel fireproof coating. Background technique [0002] With the rapid development of the national economy, urban construction is accelerating, and the floating population is increasing rapidly, the construction and improvement of transportation is particularly important. The tunnel is favored by planners and builders for its shortest distance to achieve the goal, the least occupied area, the least damage to the natural environment and landscape, and low cost. However, the tunnel structure is generally made of stones and reinforced concrete. When the temperature rises to 600°C, the strength of the concrete will lose more than 50%, and the yield stress of the steel will drop to less than 1 / 3 of the yield force at room temperature. When a fire occurs in a tunnel, the temperature is generally above 1000°C. The masonry of the tunnel cannot withstand such a high tem...
