Problems solved by technology

This technology has a certain effect when the temperature is higher than -2°C and the thickness of the ice layer is less than 2mm, but when the temperature is below -12°C and the thickness of the ice layer is greater than 10mm, the destructive power to the ice layer is extremely small and cannot effectively break the ice

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 paving materials, and particularly relates to a snow-melting and ice-melting functional type steel bridge deck paving material and a preparation method thereof. Background technique [0002] In recent years, my country has intensified efforts to build long-span steel bridges across rivers and seas. At present, my country's steel overcapacity and falling steel prices are good opportunities to promote the construction of steel structure bridges and improve the quality of highway bridge construction. Steel structure bridge construction 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 bridge's traffic capacity and traffic safety. The steel bridge deck pavement is very prone to early damage. The reasons are: the steel bridge deck pavement lacks the support of the rigid base plate and i...
