Abstract

The invention discloses a flame-retardant double-component adhesive used for a color road surface, belonging to the technical field of adhesive preparation, and suitable for the internal road surface of a long and large tunnel. The flame-retardant double-component adhesive used for the color antiskid pavement layer of a tunnel prepared by the invention comprises a component A and a component B. In application, the two components are uniformly mixed to obtain the flame-retardant double-component adhesive used for the color antiskid pavement layer of the tunnel. The adhesive is an environmentally-friendly, non-toxic, high-reflectivity, flame-retardant and smoke-suppression and high-slip-resistance adhesive used for the color antiskid pavement layer of the tunnel road surface, and can be used in surface pavement of the internal road surface of the long and large tunnel and the pavement of a tunnel gates.

Description

technical field [0001] The invention belongs to the technical field of adhesive preparation, in particular to a flame-retardant two-component epoxy system adhesive for colored pavements, which is suitable for road surfaces in long tunnels. Background technique [0002] At present, problems such as traffic jams, traffic accidents and traffic safety have become increasingly prominent in road transportation. Among many solutions, colored pavement with diversion control traffic functions has been widely used in the field of road management. [0003] With the rapid development of highway traffic in our country, there are more and more highways in various places, and the number of highway tunnels is also increasing. At present, asphalt concrete pavement is commonly used in most tunnel pavements in China to replace cement concrete pavement pavement. Compared with cement concrete pavement, asphalt concrete has the advantages of comfortable driving, low driving noise and good skid r...
