Abstract

The invention provides an anti-icing pavement sealing material and a preparation method thereof, which is made of the following raw materials: emulsified asphalt, filler, mixed solution and organic silicon polyacrylic resin; the filler is made of the following raw materials: zinc oxide, Zirconium and ferric chloride; the mixture is made from: acetylacetone, butyl acetate, cyclohexane. The present invention has undergone a large number of researches and tests, and the results show that applying the anti-icing emulsified asphalt seal material produced by the present invention to the laying of asphalt pavement can achieve the effect of melting snow and deicing, and can significantly improve the anti-icing performance and anti-icing performance of the road surface. slippery performance. In addition, this material can also form a dense waterproof layer on the asphalt pavement, which can effectively prevent water damage on the pavement, and can also play a role in sealing the cracks in the pavement, which has the effect of preventive maintenance.

Description

technical field [0001] The invention relates to the technical field of road materials, in particular to an anti-icing pavement, in particular to an anti-icing pavement sealing material and a preparation method thereof. Background technique [0002] Due to the advantages of convenient construction and maintenance and good driving stability, asphalt pavement has been widely popularized and applied in various grades of highways, and has gradually developed into the main structural form of highways in our country. However, under the influence of freezing rain and snowfall in winter, the asphalt pavement is prone to icing and other phenomena. The icing on the road surface not only has an adverse effect on driving, but also brings serious damage to the asphalt pavement, especially the "black ice" problem. Seriously endanger driving safety. Therefore, in view of the freezing problem of asphalt pavement in winter, the development of asphalt pavement sealing material with excellent ...
