Problems solved by technology

However, because roads and railway tunnels are generally located in mountainous areas, the tunnels are cool and humid, and the ventilation is poor. The existing coatings have poor adhesion and are prone to fall off, resulting in unsatisfactory fire prevention effects and short fire protection time.

Abstract

The invention discloses special waterborne fire-retardant coating for tunnels. The special waterborne fire-retardant coating is made from vinyl chloride-vinylidene chloride copolymer, chlorinated polyether resin, waterborne silicone acrylic emulsion, waterborne epoxy resin, polytetrafluoroethylene micropowder, polyvinylidene fluoride, oxidized starch, aluminum triphosphate, pentaerythritol, melamine, zinc borate, expanded perlite, zinc phosphate, phosphorus-nitrogen fire retardant, ceramic cenospheres, expanded vermiculite, bisphenol A-bi(diphenyl phosphate), antifoaming agents, antibacterial agents, solubilizer, epoxy group containing polysiloxane, fluorocarbon surfactant and deionized water. The special waterborne fire-retardant coating for the tunnels has the advantages of high adhesive power, good cohesiveness, excellent moisture resistance, mold resistance, thermal resistance and flame retardancy and applicability to fire-retardant surface coating of highway tunnels and railway tunnels.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a special water-based fireproof coating for tunnels. Background technique [0002] Tunnels not only undertake the task of transportation, but also function as channels for optical cables, cables, and even oil and water pipelines. Although the reinforced concrete components used as the main building in the tunnel are non-combustible materials, the tunnel fire has the characteristics of a rapid rise in ambient temperature after combustion, a long duration, a large fire range, and difficulties in fire fighting and entry. In a short period of time after the fire broke out, the local temperature of the fire site in the tunnel will rise rapidly to 1000°C. As the temperature continues to rise, the bound water in the concrete will turn into steam and expand, generating pressure, causing the concrete surface to burst and cause large fires. The collapse of the tunnel, the tunnel lining a...
