A kind of marking composition, preparation method and application

Abstract

The invention belongs to the field of road materials, and in particular relates to a marking composition, a preparation method and an application. A marking composition provided by the invention comprises: an organic reversible heat-sensitive color-changing material, a heat-conducting material, an adhesive, a curing agent, a heat-insulating paint and a road marking paint. A marking composition provided by the present invention, and applying it to high and low temperature early warning marking materials can effectively solve the problem in the prior art that the occurrence of high temperature or low temperature diseases cannot be judged in time, thus causing high and low temperature diseases on asphalt pavement Technical problems that seriously affect the service life of asphalt pavement due to hidden dangers.

Description

technical field

[0001] The invention belongs to the field of road materials, and in particular relates to a marking composition, a preparation method and an application. Background technique

[0002] Asphalt pavement is widely used in the field of expressways in my country because of its good smoothness, driving comfort, safety and road performance. Although asphalt pavement has a good application effect, it is prone to pavement diseases in extreme environments such as high temperature and low temperature.

[0003] Under high temperature conditions, the texture of asphalt materials becomes soft, and severe high-temperature rutting is prone to occur under the action of traffic loads. However, under low-temperature conditions, the texture of asphalt materials becomes brittle and prone to low-temperature cracking, which seriously affects the service life of asphalt pavement. Most of the existing strategies to deal with high and low temperature diseases of asphalt pavement are ...

Examples

Embodiment 1

[0042]The marking composition prepared in this example, in parts by weight, includes 23 parts of heat-sensitive ink, 9 parts of thermally conductive silica gel, 16 parts of water-based acrylic resin, 8 parts of urea-formaldehyde resin, 26 parts of two-component marking paint, silicon carbide 16 parts of ceramic paint, 11 parts of transparent thermal insulation paint, 14 parts of neopentyl glycol diglycidyl ether.
