The composite antioxidant for accounting for polymer fluid mass ratio 2~5 ‰ is put into again, and keeps the temperature 10-15 hours under the conditions of 180-200 DEG C；（4）It will
It is -0.07MPa that the polymer fluid that step (3) obtains, which delivers into top vacuum degree, and the desolventizing that 90~120 DEG C of tower top temperature evaporates tower
Interior carry out solvent removal, control reflux ratio are 2；Tower top obtains solvent of the boiling point at 85-200 DEG C, and bottom of tower obtains resin liquid；（5）
Above-mentioned resin liquid is input into the extracting of row steam distillation, top vacuum degree -0.0850MPa extracts several equal molecules by stripping
Oligomer of the amount less than 400 is to get to Petropols.
Further, preparation method includes the following steps：（1）Aromatic naphtha is added according to the parts by weight, is heated to
Under the conditions of 165-190 DEG C, rubber powder stirring melting is added, Petropols, polyurethane resin and clay are added after being completely dissolved, most
After inorganic pigment is added, be uniformly mixed.
The present invention has the advantages that：
The present invention can produce the color asphalt of various colors, improve vision, can be widely used in street, pavement and
The different places such as landscape road can not only meet the needs of various places, while can also beautify the environment.
The present invention realizes and the excellent colored drip of high temperature resistance is prepared at lower cost by being formulated global design
Green product.
