Problems solved by technology

However, the compatibility of inorganic salts in oily asphalt is poor, and the accumulation of inorganic salts will form in the system. The snow-melting agent in the deep layer of salt-storing asphalt after paving is difficult to precipitate, and a good snow-melting effect cannot be achieved.
In addition, the addition of salt-storing deicing agents will affect the road performance of the mixture to a certain extent.

Abstract

The invention belongs to the technical field of road surface coating materials, and in particular relates to a salt-storage epoxy / polyurethane composite coating material for a highway and a preparation method thereof. The technical scheme is as follows: components A, B and C are included, wherein the component A comprises waterborne epoxy resin emulsion; the component B comprises a waterborne epoxy resin curing agent, waterborne polyurethane, emulsified asphalt, rutile titanium dioxide, a defoaming agent, a flatting agent and industrial water; the component C comprises an ice melting agent and industrial water. The preparation method comprises the steps of uniformly mixing the components A, B and C according to a ratio, coating or spraying to a road surface at normal temperature and curing, so as to obtain the salt-storage epoxy / polyurethane composite coating material for the highway. The salt-storage epoxy / polyurethane composite coating material for the highway has a good active ice and snow melting function, the film-formed coating material has excellent abrasive resistance, water tolerance and high / low temperature resistance, and can perform fog seal protection and beautification on old road surfaces and micro-fractures, prevent rain water infiltration, prolong the service of the road surface and increase driving comfort, and the like.

Description

technical field [0001] The invention belongs to the technical field of pavement coating materials, and in particular relates to a salt-storage epoxy / polyurethane composite coating material for roads and a preparation method thereof. Background technique [0002] In winter in northern China or in high-altitude mountainous areas, icy and snow-covered roads are a relatively common phenomenon, which has a serious adverse effect on road smoothness and driving safety. The reduction will directly cause the car to skid and deviate on the ice and snow road, and the braking distance will be significantly extended, which will easily cause traffic accidents and seriously affect the operational stability and safety of the vehicle, which is a major hidden danger to traffic safety. Therefore, how to improve driving safety on ice and snow roads in winter, avoid or reduce the occurrence of traffic accidents, improve road traffic capacity and good road safety operation, melt ice and snow on r...
