Description
Technical field
The invention belongs to Colophonium preparing technical field is and in particular to a kind of reclaim breeze and damaged tire using asphalt mixing plant
Pyrolysis oil and rubber powder produce high performance modified bitumen method and implement the product that the method is obtained.
Background technology
Building stones used by bituminous concrete produces can produce dust in the production process of rock crushing plant, and dust adhesion is in stone
Asphalt mixing plant can be transported therewith on material.During asphalt mixing stands in bituminous concrete, need building stones are carried out scraper,
Conveying, heating and mix, dust can emit pollution environment, and mixing station needs by bag-type dust collector, dust to be carried out back
Receive.Dust fraction after recovery can be re-added in asphalt, and major part all cannot can only be discarded in use, disposes
Improper meeting land occupation, processing of serious environment pollution, therefore abandoned mine powder is always one of difficult problem perplexing asphalt mixing plant.But
These abandoned mine powder are very little due to volume, and particle diameter, substantially all in below 0.075mm, has good specific surface area, and activity is preferable,
It is easy to react with Colophonium and other materials.These abandoned mine powder have certain intensity simultaneously, are good filleies, permissible
Improve the mechanical property of Colophonium.Most of all, by including SBS and damaged tire with various modified asphalt materials in process of production
There is " grafting " reaction in rubber powder etc., be effectively improved the isolation problem of modified pitch.
And the development with Domestic Automotive Industry, create increasing junked tire.The process of existing junked tire
Mode includes tyre rebuilding, grinds to form rubber powder making reclaimed rubber.Wherein tyre rebuilding has number of times to limit, when renovation is to necessarily
Number of times does not allow for being renovated again, can only discard, and grinds to form rubber powder, and part rubber powder is used for producing road rubber asphalt.Rubber
Glue Colophonium has a good pavement performance, and has the environment protection significance of certain cyclic utilization of waste, is necessarily promoted.But rubber
Asphalt viscosity big it is necessary to produce under the high temperature conditions and building stones mix and stir construction, the flue dust of volatilization is larger, abnormal smells from the patient is heavier, is promoting
During also receive certain resistance.Tire with the addition of substantial amounts of furfural oil in process of production, after furfural oil is reacted with rubber
There is good performance, by junked tire is carried out with Pintsch process, the oily oils and fatss reacted with rubber of original furfural can be analysed
Go out, partly used as inferior fuel, calorific value is not high, but discharge is very serious, therefore domestic limit its use.
Content of the invention
For above-mentioned deficiency, one of the object of the invention is, provides a kind of technique simple, it is easy to accomplish, can be replaced it
