Abstract

The invention discloses a deicing and snow-melting functional steel deck pavement material and a preparation method thereof. The deicing and snow-melting functional steel deck pavement material comprises three components A, B and C at the mass ratio of 100:(20-60):(150-350), wherein the component A is prepared from epoxy resin, an elastic modifier, an epoxy active diluent, an antifoaming agent and a dispersing agent; the component B is prepared from an epoxy hardener, a curing accelerator, a coupling agent and a pigment; and the component C is prepared from waste rubber powder, waste rubber particles, magnet powder and a whisker. According to the deicing and snow-melting functional steel deck pavement material, efficient deicing and snow-melting are achieved by adopting the synergistic effect of three modes, such as strain ice-breaking, strain heat release and microwave radiation heat generation. Compared with the prior art, the material disclosed by the invention is good in deformability, appropriate in strength, good in water-tightness, good in adhesive property, small in specific gravity, convenient to construct and maintain, low in deicing and snow-melting cost, low in energy consumption, high in efficiency, environment-friendly and wide in application prospect.

Description

technical field [0001] The invention belongs to the technical field of bridge deck pavement materials, and in particular relates to a snow-melting and ice-melting functional steel bridge deck pavement material and a preparation method thereof. Background technique [0002] In recent years, my country has intensified its efforts to build long-span steel bridges across rivers and seas. At present, my country's steel production capacity and steel prices have fallen, which is a good opportunity to promote the construction of steel structure bridges and improve the quality of highway bridge construction. The construction of steel structure bridges has become an industry consensus. [0003] Bridge deck pavement is an important part that affects the quality of steel bridge engineering, and directly affects the traffic capacity of the bridge and the safety of driving. The steel bridge deck pavement is prone to early failure, the reasons are: the steel bridge deck pavement lacks rigi...
