Problems solved by technology

[0010] As far as these methods are concerned, if a fire really breaks out in a tunnel, the automatic sprinkler system and fireproof coating are not very useful, and the fireproof coating is easy to age and fall off; according to the relevant report of the World Road Association (PIARC), most The state believes that the vast majority of tunnel fires occur in fuel tanks and carriages, and sprinkler systems are of little use

Abstract

The invention relates the tunnel flame-resistant plate, comprising the following steps: using magnesium chloride and magnesium oxide as binder, using porcelain clay, volcanic ash, tabular spar, diatom earth and aluminium silicate as main material, using organic and inorganic compound salt as modified contaminant, using fortifying fiber (glass fiber) as reinforced materials, stirring, extrusion forming, and getting high-strength material.

Description

technical field [0001] The invention relates to a tunnel fireproof material, in particular to a tunnel fireproof board applied to tunnel fireproofing. Background technique [0002] Tunnel fire not only seriously threatens human life and property safety, but also may cause huge damage to traffic implementation and human production activities. Therefore, in the past 20 years, various countries have devoted considerable efforts to conduct extensive research on tunnel fire behavior and fire protection. [0003] In the Chinese patent CN2196656 silicon-magnesium layer heat-insulating fireproof board (disclosed in 1995), it relates to a fireproof building decoration board, which is characterized in that the upper surface of the fireproof board is a shell layer, and a three-dimensional network insulation layer is bonded under the shell layer, which is generally made into a rectangular shape. or square. The shell material composition of the silicon-magnesium layer heat-insulating f...
