Embodiment

[0024] A fire-proof and waterproof coating for tunnels, which is characterized in that it is composed of composite binder, fire-resistant and heat-insulating material, expansion foam material, and flame-retardant and smoke-eliminating material. The components of the formula are as follows;

[0025] Composite binder 45%

[0026] Refractory insulation 40%

[0027] Expanded foam material 8%

[0028] Flame retardant and smoke suppressing material 7%

[0029] The proportions of the above components and ingredients are all calculated by weight percentage.

[0030] The composite binder is composed of 30% high alumina cement CA-50, 6% silica fume, 2% redispersible rubber powder RI551Z, 0.3% hydroxypropyl methylcellulose, and 9% osmotic crystalline active masterbatch, of which the active The masterbatch consists of 25% instant sodium silicate powder, 45% lime calcium powder, 25% aluminum hardate, 4.4% naphthalene-based water reducer, 0.15% air-entraining agent, 0.15% active agent, a...

Abstract

The invention discloses a fireproof and waterproof coating for tunnel. The coating comprises composite binder, refractory insulating material, expansion and foaming material and flame-resistant and smoke-eliminating material. The preparation method of the fireproof and waterproof coating for tunnel comprises the following steps: 1. screening, mixing and dispersing; and 2. mixing and the like. The invention has the advantages of thin coating, high fire endurance and bonding strength, excellent flexibility and crack resistance and good water resistance and waterproof property; and the coating is resistant to freezing and thawing, is environmentally friendly and nontoxic, has low cost, is convenient to popularize and use, and is applicable to the coating protections of various tunnels, underground projects, petrochemical devices, and buildings and steel structures which have demands of fire resistance, water resistance and thermal insulation.

Description

[0001] Field of invention [0002] The invention relates to the technical field of building materials, in particular to a fireproof and waterproof coating for tunnels. Background technique [0003] At present, with social progress and rapid economic development, road and railway transportation networks are developing rapidly around the world, and there are more and more tunnel projects. Tunnels are not only channels for transportation, but also channels for optical fiber cables, power transmission cables, and oil and water transportation. Therefore, the fire in the tunnel is the traffic accident with the largest economic loss, the most difficult repair, and the longest interruption of driving time. In order to prevent the reinforced concrete structure in the tunnel from being damaged in the event of a fire and minimize the economic loss, it is an economical and effective method to protect the tunnel concrete with fire-resistant paint. Due to the poor environment of the tunne...
