Embodiment 1

[0015] Using absolute ethanol as a solvent, add anatase-type nano-titanium dioxide (with a particle size of 5 to 10 nm) and a titanate coupling agent in a weight ratio of 100:1 (operating unit: kilogram) into absolute ethanol, Prepare a suspension solution, then ultrasonically disperse for 30 minutes, and then spin evaporate to remove ethanol. The powder is vacuum-dried at 60°C for 12 hours, ground and sieved to obtain the target excipient.

Embodiment 2

[0017] Using absolute ethanol as a solvent, add anatase-type nano-titanium dioxide (with a particle size of 5-10 nm) and a titanate coupling agent in a weight ratio of 100:2 (operating unit: kilogram) into absolute ethanol , made into a suspension solution, then ultrasonically dispersed for 30 minutes, and then the ethanol was removed by rotary evaporation, and the powder was vacuum-dried at 60°C for 12 hours, ground and sieved to obtain the target excipient.

Embodiment 3

[0019] Using absolute ethanol as a solvent, add anatase-type nano-titanium dioxide (with a particle size of 5 to 10 nm) and a titanate coupling agent in a weight ratio of 100:3 (operating unit: kilogram) into absolute ethanol, Prepare a suspension solution, then ultrasonically disperse for 30 minutes, and then spin evaporate to remove ethanol. The powder is vacuum-dried at 60°C for 12 hours, ground and sieved to obtain the target excipient.

Abstract

The invention discloses an auxiliary material for enhancing the high-temperature stability and aging resistance of colored asphalt binders, which is prepared by mixing nano-titanium dioxide and a coupling agent at a weight ratio of 100:0.5-5. The invention also discloses the application of the auxiliary material in preparing the colored asphalt binder with high temperature stability and aging resistance. The service performance and service life of the colored asphalt binder prepared by using the auxiliary material of the present invention are significantly improved, the application range of the colored asphalt is further broadened, and the paving of the colored asphalt pavement of urban bus lanes, bicycle lanes, sidewalks, squares and other special passages can be greatly facilitated. It has a good application prospect.

Description

technical field [0001] The invention relates to an auxiliary material for enhancing the high-temperature stability and aging resistance of colored asphalt binder and its application, which belongs to the technical field of road materials. Background technique [0002] Colored asphalt pavement refers to mixing colored asphalt binders, aggregates, pigments and additives at a specific temperature, and then paving and rolling to form a pavement with certain strength and use function. Colored asphalt pavement has the advantages of coordinating with the surrounding environment, beautifying the city, relieving driving fatigue, promoting driving safety, reducing road noise, and alleviating the "heat island effect". Using modern petrochemical products, colored asphalt binders comparable to petroleum asphalt can be artificially prepared, and a certain color can be made by adding certain pigments. Colored asphalt binder is the main component of colored asphalt, which is generally ligh...
