Problems solved by technology

At present, the fire-resistant coatings used in tunnel construction are basically thick-coated fire-resistant coatings of inorganic thermal insulation mortar. Although the coating has good fire-resistant and heat-insulating properties, it also has shortcomings that are difficult to overcome: (1) Poor water resistance, Since the coating has a rough porous structure, developed capillary structure, and poor waterproof and anti-seepage performance, the thermal resistance of the coating decreases after moisture absorption, and the fire a

Abstract

The invention discloses a water expansion type fire-proof mildew-proof coating for tunnels, which are prepared through conventional preparation processes with the cooperation of auxiliary agents, wherein silicone acrylic emulsion serves as a film forming matter, modified ammonium polyphosphate, melamine, dipentaerythritol and azodicarbonamide serve as fire retardants; titanium dioxide, zinc borate and expansible graphite serve as fillers; nanometer SiO2 serves as a modified material and an anion antibacterial additive serves as a mildew-proof bactericide. The mildew-proof fire-proof protective coating disclosed by the invention has the advantages of long fire-proof time limit, good adhesion property, water resistance and permeability resistance, mildew resistance and antibacterial property, environmental protection and no toxicity, good decorative effect, thinness in coating and convenience for construction and is suitable for various tunnel walls.

Description

Technical field [0001] The invention relates to the technical field of fireproof coatings for tunnels, in particular to a water-based expansion type fireproof and anti-mildew coating for tunnels. Background technique [0002] As we all know, the development pattern of the world economy today has brought about the rapid development of the transportation industry, especially the rapid development of ground and underground transportation. And in ground and underground transportation, no matter be iron road, railway, subway, all comprise a large amount of tunnels, the total length of tunnel is a huge number. Tunnels are not only channels for transportation, but also channels for optical fiber cables, power transmission cables, oil, water and sewage. Once a fire breaks out in the tunnel, the reinforced concrete structure will easily burst and collapse due to thermal expansion. Fire accidents in tunnels are traffic accidents with the largest economic losses, the most difficult r...
