A kind of fireproof coating for inner wall of highway tunnel and preparation method thereof

Abstract

The invention relates to a fireproof coating for an interior wall of a highway tunnel and a preparation method of the fireproof coating. A bottom layer material and a surface layer material are prepared and packaged for standby use; the bottom layer material can be composited with multiple bottom boards; no matter whether a natural stone surface material or a man-made waterproof and moisture-proof stone surface material is adopted, the problem of poor porous adsorbability of the natural stone surface material can be solved after composition, the problems of efflorescence, whitening, cracking, tilting and the like can be solved, and meanwhile, the defects that the flame retardance of a manmade board is poor, the bonding strength is reduced and deformation, hollowing, tilting, infirm bonding and the like are caused can be overcome. After the bottom layer material is adopted, the external surface layer material is composited, meanwhile, the fireproof coating has the effects of light absorption, no light reflection, moisture prevention, water resistance, high performance, flame retardance and fire prevention, the bottom layer and the surface layer are combined for use, multiple physical defects of existing tunnel inner board materials can be overcome, chemical defects of the boards are overcome, and accordingly, the inner wall of the tunnel has effective waterproof and moisture-proof functions and also has efficient flame-retardant and fireproof effects.

Description

technical field [0001] The invention relates to the field of road construction, in particular to a fireproof coating for the inner wall of a road tunnel and a preparation method thereof. Background technique [0002] At present, after the construction of the tunnel building is completed, it is necessary to decorate the inner wall of the tunnel. There are many types of decorative materials for the inner wall of the tunnel. No matter what kind of material is used for the interior panel, the panel needs to be treated with moisture-proof and fire-proof treatment. Due to the influence and limitation of natural conditions, the waterproof, moisture-proof and fire-proof effects of the inner wall of the tunnel must meet certain standards. In a tunnel that does not see sunlight for a long time, if no special treatment is carried out, various problems will occur in the long-term use of interior wall materials, such as pan-alkali bleaching, cracking, warping, etc., and there are certain...

AI Technical Summary

Problems solved by technology

In a tunnel that does not see sunlight for a long time, if no special treatment is carried out, various problems will occur in the long-term use of interior wall materials, such as pan-alkali bleaching, cracking, warping, etc., and there are certain restrictions on the material itself

[0003] At present, natural stone or artificial stone is mostly used for interior walls in tunnels. Natural stone is prone to reflections in the tunnel, causing the lights of passing vehicles to shine on the stone to form multiple light reflections, resulting in frequent accidents in the later period.

The use of artificial stone decoration materials inherits the excellent waterproof and corrosion-resistant effects of natural stone and has its own unique excellent performance. However, due to the limitations of the material itself, it has great defects in moisture-proof, waterproof and fire-resistant aspects. During construction, not only It is very difficult, and after long-term use, there will be defects such as reduced bond strength and deformation, and some even have problems such as hollowing, warping, and weak bonding.
