Waste and old asphalt thermal circulation recycling regenerating agent and preparation method thereof
ActiveCN102786806AImprove the safety of useReduce volatilityBuilding insulationsPetroleum resinPlasticizer
The invention provides a waste and old asphalt thermal circulation recycling regenerating agent which has a prescription comprising extract oil from fourth side line of a vacuum tower, epoxidized soybean oil, turpentine and petroleum resin, wherein the epoxidized soybean oil serves as a plasticizer and softener. The waste and old asphalt thermal circulation recycling regenerating agent has various physicochemical indexes obviously higher than those of commercially available waste and old asphalt regenerating agent, and meets the national recommended standard; more important, the epoxidized soybean oil is adopted as the plasticizer and the softener instead of dibutyl phthalate DBP and dioctyl phthalate DOP, so that the quantity of violated harmful substance is lower, and the safety of the regenerating agent in use is improved.
