Problems solved by technology

Although small molecular monomers can participate in the polymerization reaction, during the polymerization process, small molecular monomers can also be absorbed by the capillary pores of asphalt or cement concrete, resulting in insufficient adhesion between the material and the base surface after curing. Delamination and peeling after time
In the actual application process, in order to solve the above shortcomings, it is usually necessary to coat the base surface with epoxy primer. The advantages of rapid polymerization and curing at room temperature or low temperature, so that it is impossible to realize the rapid paving of colored anti-skid thin layers on the road surface

Abstract

The invention discloses a colored anti-skid pavement material, a preparation method and application thereof, and belongs to the technical field of road pavement materials. Its components are: polyurethane acrylate, diol diacrylate, aromatic tertiary amine, hydroxyacrylate, liquid paraffin, solid paraffin, inorganic calcium filler, inorganic pigment, inorganic siliceous filler, calcined ceramic aggregate and liquid peroxide initiator. The colored non-slip paving material prepared by the present invention does not contain small molecule solvent-based monomers capable of dissolving asphalt or penetrating into the cement concrete pavement, and has high bonding strength with the pavement, and the material itself has good high-temperature stability and low-temperature crack resistance, The anti-skid coefficient is high, the service life is long, and the preparation process is simple, the conditions are mild, the safety and environmental protection are simple and fast, and the construction has extensive practical value in road paving.

Description

technical field [0001] The invention belongs to the technical field of road pavement materials, and in particular relates to a colored non-slip pavement material and its preparation method and application. Background technique [0002] On roads with steep slopes, roads around schools, urban non-motor vehicle lanes, tunnel entrances, park landscape roads and other roads, in order to prevent vehicle skidding due to high humidity or icing, the road surface is coated with various anti-skid pavement materials, Ensure the safety of vehicles and people driving or walking on these roads. [0003] In recent years, due to the rapid polymerization of methacrylate or acrylate at room temperature or low temperature through a redox initiation system, pavement colored anti-skid materials based on methacrylate or acrylate binders have been widely used. Patent CN201610863872 proposes a colored non-slip thin-layer paving material based on methacrylic resin MMA and its preparation process. H...
