Abstract

The invention relates to a preparation method of a material for a microwave deiced road surface and belongs to the technical field of road pavement. The material is prepared from a component A and a component B according to the mass ratio of (2 to 2.5) to (3 to 4), wherein the component A is prepared from the following raw material: diphenylmethane isocyanate with the functionality of 2.0 to 2.7;the component B is prepared from the following raw materials: 20 to 45 percent of double-functional-group polyether alcohol, 10 to 20 percent of inorganic filler, 5 to 10 percent of a chain extender,5 to 10 percent of a catalyst and 15 to 45 percent of a wave absorbing agent. The material for the microwave deiced road surface, provided by the invention, is mainly used for road surface construction; when the material is paved on the road surface, the material has wave-absorption and temperature-raising deicing properties; after the component A and the component B in the material for the microwave deiced road surface are mixed according to a ratio, chemical crosslinking reaction occurs and excellent properties including high initial viscosity, rapid curing speed, good road surface wave absorption performance and high surface temperature are realized.

Description

technical field [0001] The invention belongs to the field of chemical industry and relates to a road pavement technology, in particular to a novel microwave deicing pavement material and its preparation method and application. Background technique [0002] The snow and ice on the road not only seriously affects the smooth flow of road traffic, but also easily causes traffic accidents and huge losses. At present, among the methods of snow melting and deicing at home and abroad, the removal rate of manual cleaning method and mechanical power method is relatively low. It is a chloride, which is easy to corrode and damage the road structure and motor vehicles, and will also bring environmental pressure to the surrounding areas. In recent years, bio-based snow melting agents have been developed abroad and have achieved certain results; the snow and ice removal performance of rubber particle filling road surface technology is affected External environmental conditions such as tem...
