Problems solved by technology

[0006] Anti-icing technology is an active ice and snow removal technology for asphalt pavement that has been popularized and applied in the market. By adding components to the pavement material that can reduce the freezing point of the pavement, although it can inhibit the icing of the pavement or reduce the adhesion between the pavement and ice The function of "light snow does not freeze, heavy snow is easy to de-ice" is realized, but the durability is not enough
Moreover, in the anti-icing sealant material of the emulsified asphalt system in the prior art, the anti-icing agent releases Na when it encounters water. + , Ca 2+ , Mg 2+ , Cl - Plasma will cause rapid demulsification of emulsified asphalt in the seal layer containing sand mist, resulting in thickening and segregation of the system

Abstract

The invention discloses an anti-freezing coating material for a road and a preparation method of the anti-freezing coating material, and belongs to the field of road engineering tests. The coating material is prepared from a main solvent I, an asphalt cement, a slow-release type anti-freezing agent, a functional filler, a modified master batch and a stabilizer according to a specific ratio, the tested Brookfield viscosity of the coating material at 20 DEG C is 2000-4000 cPs, the freezing point of a sprayed pavement is smaller than or equal to-3 DEG C, the ice melting rate is larger than or equal to 20%, the salt release amount is smaller than or equal to 0.4%, and the moisture absorption rate is smaller than or equal to 0.7%. Compared with the prior art, the slow-release anti-freezing agent and the hydrophobic coating material are adopted to achieve a synergistic effect, distribution is stable, processing is convenient, the implementation process is simple, the waterproof function of the pavement is improved, the low-freezing-point and anti-freezing functions are achieved, the road driving safety and durability in snowy days are effectively improved, and the good application and popularization value is achieved.

Description

technical field [0001] The invention relates to the field of road engineering, and specifically provides an anti-icing coating material for roads and a preparation method thereof. Background technique [0002] After the rain and snow in winter, the accumulated water and snow on the road surface are easy to freeze in the low temperature environment, resulting in a sharp decline in the anti-skid performance of the road. Driving on ice and snow roads is very easy to skid, and the emergency braking distance is greatly increased, which poses a serious threat to the life and property safety of pedestrians and vehicles, easily causes serious traffic jams and induces a series of traffic accidents. Therefore, many countries attach great importance to the research and application of road anti-ice and snow technology. Europe, America, Japan and other countries started earlier in the research and application of road ice and snow removal technology, and have done a lot of research, but ...
