Description
Technical field
The present invention relates to reducing agent, in particular to a kind of high-performance waste asphalt reducing agent and preparation method thereof.
Background technique
With gradually forming for highway in China net, a large amount of highways that China is built early stage come into medium-capital overhauling maintenance
Phase.Thus a large amount of waste asphalt mixture will be generated.If these waste asphalt mixtures, which cannot obtain effectively recycling, to be made
With being not only a kind of significant wastage of resource, it is often more important that heavy environmental pressure can be generated.If these can efficiently be utilized
Waste asphalt mixture can not only be saved and largely gather materials and petroleum resources, while can produce immeasurable environmental benefit.
However although there are many producer of waste asphalt reducing agent available on the market, product quality is irregular, and product cost is very
It is low.Most waste asphalt reducing agent is true only to restore waste asphalt performance only from reduction waste asphalt performance indicator
Index is easily accomplished.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of high-performance waste asphalt reducing agents.
In order to solve the above-mentioned technical problem, the technical solution of the present invention is as follows: a kind of high-performance waste asphalt reducing agent, described
Pitch reducing agent be made of following component according to weight ratio: polyvinyl resin: high molecular polymer: plant base resin be 40~
60:20~30:15~35.
The invention also discloses the preparation methods of above-mentioned high-performance waste asphalt reducing agent, including the following steps: 1) will plant
Object base resin, high molecular polymer carry out circulation stirring at 100-150 DEG C, obtain substance A；
2) additive polyvinyl resin is added into substance A, is heated to 120-160 DEG C of circulation stirring 1h.
Third object of the present invention is to disclose the application method of above-mentioned high-performance waste asphalt reducing agent, and described goes back
The dosage of former agent is the 0.5-1.0% of waste asphalt quality.
Production technology very simple of the present invention need to only carry out heat cycles stirring；Reduction effect is significant, according to waste asphalt
Appropriate this product is added in performance indicator, can be by waste asphalt performance recovery to primary pitch index level；This product construction party
Just, when practice of construction, it need to only be added in new pitch, stir evenly, production of other construction technologies with asphalt
Technique, and this product storage stability is good.
Specific embodiment
Specific embodiments of the present invention will be further explained below.It should be noted that for these implementations
The explanation of mode is used to help understand the present invention, but and does not constitute a limitation of the invention.In addition, invention described below

Embodiment 3:
A kind of high-performance waste asphalt reducing agent is made of following component according to weight ratio: polyvinyl resin: polyphosphazene polymer
Close object: plant base resin is 50:25:30.
Preparation method is as follows:
1) plant base resin, high molecular polymer are subjected at 100-150 DEG C circulation stirring, obtain substance A；
2) additive polyvinyl resin is added into substance A, is heated to 120-160 DEG C of circulation stirring 1h.
In the present embodiment, the dosage of reducing agent is the 0.5-1.0% of waste asphalt quality.
Waste asphalt performance indicator can be not only restored to primary pitch index level by this product, and can be obtained good
Regenerating mixture pavement performance, such as high-temperature stability (still keeping stablizing at 60 DEG C)；(- 10 DEG C can resist crack resistance at low-temperature
It splits)；Water stability and weatherability.
In order to further prove the beneficial effect of the application, now enumerating following experiments example, (RA is the production of the application in following table
Product): wherein table 1 is that primary pitch performance indexes is restored to after joined product of the invention, and table 2 is that joined the present invention
Product after reached regenerative mixed road material performance indices.Wherein, old material addition ratio is 50%.
