Abstract

The invention discloses a pavement wearing layer with efficient snow melting and deicing functions and a preparation method thereof. The pavement wearing layer is composed of a component A, a component B and a component C. The component A is composed of hydrogenated bisphenol A type epoxy resin, nano titanium dioxide graft modified epoxy resin, an elastic modifier, polyphenoxy resin PKHB, diglycidyl aniline, BYK-066N, BYK-163 and fumed silica. The component B is prepared from polyoxypropylene triamine T-403, 1, 3-bis (aminomethyl) cyclohexane, a modifier of m-xylene diamine, o-hydroxybenzyl dimethylamine, isopropyl tri (isostearoyl) titanate, pigment zinc powder and fumed silica. The component C is prepared from steel slag powder particles, powdery graphene and short carbon fibers. Compared with the prior art, the pavement wearing layer of the invention has the advantages of low energy consumption, low cost, convenience in construction and maintenance, high electrothermal conversion efficiency, good snow and ice melting efficiency, long service life, obvious environmental protection benefit and the like, and has wide application prospects.

Description

technical field [0001] The invention belongs to the technical field of functional coatings, and in particular relates to a pavement wearing layer with high-efficiency snow-melting and ice-melting functions 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 manage...
