Abstract

The invention discloses a snow-melting and deicing coating layer for a pavement and a preparation method of the snow-melting and deicing coating layer, and belongs to the technical field of functional coating layers. The snow-melting and deicing coating layer for the pavement is obtained by mixing components A, B and C, spraying the mixture to the pavement or coating the pavement with the mixture, and curing the mixture; the mass ratio of the components A, B and C is 100: (20 to 60): (70 to 150). The component A is prepared from epoxy resin, an elastic modifier, an epoxy active diluent, a snow melting agent and a dispersing agent; the component B is prepared from an epoxy curing agent, a curing promoter, a coupling agent and a pigment; the component C is prepared from quartz powder, magnet powder and crystal whiskers. The snow-melting and deicing coating layer realizes efficient snow melting and deicing under the synergistic action of the snow melting agent and microwave radiation heating. Compared with the prior art, the snow-melting and deicing coating layer for the pavement has the advantages of low energy consumption, convenience for construction and maintenance, low cost, low technical requirement, high snow melting and deicing efficiency, obvious environmental protection benefit and the like, and has a wide application prospect.

Description

technical field [0001] The invention belongs to the technical field of functional coatings, and in particular relates to a pavement snow-melting and deicing coating and a preparation method thereof. Background technique [0002] Transportation is the main artery of the national economy, and snow and ice on roads seriously affect traffic safety and traffic efficiency, and are one of the important restrictive factors for economic development in high-cold and high-cold regions. Snow and icing lead to a significant decline in the anti-skid performance of the road surface, which is extremely detrimental to the driving dynamics and safety of the vehicle. How to effectively solve the problem of not closing the road or reducing the road closure in ice and snow days, avoiding traffic accidents or less traffic accidents, and forming a good The safe management mode of traffic management has become one of the important tasks of the traffic management department. [0003] At present, my...
