Pavement marking capable of performing retro-reflection on electromagnetic waves

Abstract

The invention discloses a pavement marking capable of performing retro-reflection on electromagnetic waves. A water-based marking material adopted by the pavement marking comprises components in parts by weight as follows: 15-25 parts of nano glass powder, 10-15 parts of nano metal powder, 4-10 parts of strontium aluminate phosphor, 4-13 parts of ethylene glycol, 1-5 parts of an antifoaming agent, 1-5 parts of a heat stabilizer, 1-5 parts of a flame retardant and 15-20 parts of water. The pavement marking has the characteristics of low energy consumption, environmental protection and wide application range, meanwhile, an electromagnetic transceiving device for transmitting and receiving electromagnetic waves is arranged in a vehicle body, the electromagnetic waves are transmitted on the dependence of the pavement marking and are reflected by the nano glass powder and the nano metal powder when the vehicle body approaches the pavement marking, and the electromagnetic transceiving device can determine the position of the vehicle according to the interval of the electromagnetic wave transmitting time and the electromagnetic wave receiving time. Safe driving of the vehicle is guaranteed.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a pavement marking capable of retroreflecting electromagnetic waves. Background technique [0002] With the continuous deepening of urbanization in our country, the construction of roads is becoming more and more rapid, and the demand for road markings is also increasing. Used as traffic lane markings on cement and asphalt asphalt and concrete pavements, used as lane separation lines or police lines. It is widely used in the finishing of traffic signs on urban roads, ordinary roads and expressways such as floors, curbs, residential areas, parking lots, factories and mines, highways, asphalt, and cement pavements. It can also be used in airports, warehouses, docks and other occasions where lines need to be drawn. Pavement paint not only plays the role of decorating the road surface, but also has the function of warning drivers, thus ensuring the safety of driving and pedestrians. [000...
