Abstract

The invention discloses a road petroleum asphalt anti-ageing agent, which comprises an additive B and a foundation soft component C, wherein the additive B accounts for 10-60 percent by weight ratio, and the foundation soft component C accounts for 90-40 percent by weight ratio; the foundation soft component C is road petroleum asphalt or aromatic hydrocarbon-rich component or a mixture of the road petroleum asphalt and the aromatic hydrocarbon-rich component; the additive B comprises the following components in the weight ratio: 30-55 percent of a radical scavenger, 15-30 percent of peroxide decomposer, 10-20 percent of light stabilizer and 10-40 percent of metal ion complexing agent. A preparation method for the road petroleum asphalt anti-ageing agent comprises the following steps: heating the foundation soft component C to 70-150 DEG C; respectively adding all the components in the additive B under the stirring condition; and evenly stirring to obtain the road petroleum asphalt anti-ageing agent. The road petroleum asphalt anti-ageing agent disclosed by the invention has the characteristics that anti-ageing performance is good, the use level is low and the compatibility between the road petroleum asphalt anti-ageing agent and the asphalt is good, and is capable of restraining and preventing chain reactions caused on the road petroleum asphalt because of heat, oxygen, light and metal ions, and prolonging the service lives of asphalt road surfaces.

Description

technical field [0001] The invention belongs to the technical field of road petroleum asphalt, and mainly relates to a road petroleum asphalt antiaging agent and a preparation method thereof. Background technique [0002] During the production, storage, transportation, construction and use of road petroleum asphalt, due to long-term high-temperature environment and / or exposure to the air, its physical and chemical properties are affected by factors such as heat, oxygen, light and water. The process of road performance deterioration is called asphalt aging. The anti-aging performance (that is, durability) of asphalt is closely related to the service life of the road. Due to the limitation of crude oil resources and production technology, a considerable part of road petroleum asphalt has poor anti-aging performance, and its residual penetration ratio and residual ductility after the film oven test cannot meet the index requirements, so it can only be used as a low-grade road....
