Problems solved by technology

[0003] At present, in the field of fire protection and heat preservation of tunnels, the fire-proof paint is directly sprayed on the surface of the second lining of the tunnel. Since the surface of the second lining of the tunnel is smooth, there are oil stains, fake leather, etc., the bonding strength between the fire-proof paint and the second lining is not high, and it is easy to In addition, in the cold and severe cold regions of our country, tunnels generally only do fire prevention and ignore the thermal insulation performance and effect of the tunnel, which does not have any anti-freezing and thawing effect on the tunnel lining, and causes great frost damage to the tunnel
In recent years, global forest resources are becoming increasingly depleted, social

Abstract

The invention relates to a tunnel fire-proof and heat-preservation sheet for an alpine region and a manufacturing method of the tunnel fire-proof and heat-preservation sheet material. The fire-proof and heat-preservation sheet is composed of a surface layer and a heat-preservation layer, the surface layer and the heat-preservation layer are bonded by a high-strength adhesive layer, the surface layer is modified wood, the surface of the surface layer is sprayed with a high-expansion fire-proof coating layer, and the heat-preservation layer is a high density hydrophobic rock wool sheet. Comparedwith the prior art, the fire resistance of the sheet is obvious, the sheet can be rapidly expanded or carbonized when a fire occurs, the fire resistance limit is long, freeze-thaw resistance is high,surface strength is high, and the sheet is not easy to crack and pulverize.

Description

technical field [0001] The invention relates to a fireproof and thermal insulation board, in particular to a tunnel fireproof and thermal insulation board used in alpine regions and a manufacturing method thereof. Background technique [0002] As my country's highway and railway construction focus continues to move westward, the construction of highway and railway tunnels has increased year by year. Due to the special natural geographical environment in high-altitude areas, the freezing damage of conventionally constructed tunnels is extremely prominent. Especially when the area where the tunnel is located has typical plateau continental climate characteristics, it is necessary to install a composite insulation layer and a fireproof layer on the surface of the second lining of the tunnel, and adopt the rapid construction method of installing the tunnel arch wall insulation board to prevent the tunnel from freezing damage in winter and during operation. fire safety.
