Description
Technical field
The present invention relates to ground surface material field, particularly relate to a kind of Binder for Colored Pavement, compound and preparation method thereof.
Background technology
The bituminous paving of black common in current city and the cement concrete pavement of Lycoperdon polymorphum Vitt, the performance on both road surfaces, structure and technique are well known.Along with the progress of expanding economy and society, the roads such as major urban arterial highway and other car lanes, bicycle lane, footpath except daily pavement performance, are proposed new requirement by people in traffic obstruction, traffic guiding and road surface are attractive in appearance etc..Colored road surface can make people produce joyful sensation (such as sports center, shopping mall, parking lot, circular bicycle road etc.), the road safety marker of danger zone is (such as lay-by, crossroad, stop in emergency band etc.) and road visuality is required high place, for strengthening road surface running vehicle safety, warning vehicular traffic, specification category of roads, facilitate operational management, safeguard traffic safety etc..
In recent years along with green road, bicycle capacity, BRT public transportation lane popularization and application, and people are to urban pavement color multiple demands, colored road surface occurs in increasing city, and the visual effect good due to it and strong color difference are particularly well-suited to the road surfaces such as green road, bicycle capacity, BRT special lane, expressway tol lcollection mouth.
Colour asphalt pavement is an important component part of colored road surface, and it has the advantages such as high, bright in luster, the excellent road performance of comfort level, occupies main status at present in the coloured silk technology of road surface.
Conventional Binder for Colored Pavement mainly has two kinds: the first is that traditional albertite is decoloured, existing Colophonium decolouring technology is to be completed by reduced pressure distillation process under the high temperature of 180 DEG C, the requirement of process conditions and equipment is comparatively harsh, and Colophonium is after desolventing technology, color is still impure, is still with variegated group.When arranging in pairs or groups with other pigment, form and aspect, intensity of colour and saturation are also undesirable.Another kind is polymeric petroleum resin (C5 ~ C10), heavy mineral oil, thermoplastic elastomer, plastics, age resister, heat stabilizer and ultra-violet stabilizer etc. when 140 ~ 220 DEG C, form a kind of homogeneous and that there are the several functions such as the bonding of similar albertite, waterproof, anticorrosion and insulation high molecular polymer cementitious matter, but this cementitious matter is affected by its raw material, unstable properties, has certain difference with albertite Pavement Performance.
Restriction due to conditions such as domestic technical merit and raw materials, although both the above cementitious matter can meet the pavement performance requirement of the inferior grade roads such as green road, bicycle lane, but cannot meet the pavement performance requirement of the such as high grade pavement such as BRT road, expressway tol lcollection mouth.It addition, the raw material of preparing of both the above Binder for Colored Pavement is required for using asphalt or Petropols, there is the deficiencies such as relatively costly and complex process.
Summary of the invention
What present invention mainly solves technical problem is that existing Binder for Colored Pavement unstable properties, relatively costly and complicated process of preparation, there is provided a kind of less costly, preparation technology simple and the Binder for Colored Pavement of stable performance, the pavement performance requirement of high grade pavement can be met.
For solving above-mentioned technical problem, the technical scheme that the present invention adopts is: a kind of Binder for Colored Pavement, is made up of following components: molten state waste or used plastics mixed liquor 850 ~ 900 parts；Modifying agent 30 ~ 80 parts；Synthesis plasticizer 10 ~ 50 parts；5 ~ 10 parts of age resistor；Ultra-violet protecting agent 5 ~ 10 parts；Wherein, above number is all by weight.
Preferably, described molten state waste or used plastics mixed liquor by waste or used plastics 300 DEG C, 6MPa when melted 6 hours, then isolate not fusant be cooled to 200 ~ 250 DEG C and prepare.
Preferably, described waste or used plastics is one or more of PE, PP, PVC, PET and ABS.
Preferably, described modifying agent include phenolic resin, polyurethane, alkyd resin one or more.
Preferably, described synthesis plasticizer is adjacent benzene class plasticizer.
For solving above-mentioned technical problem, another technical solution used in the present invention is: the preparation method providing a kind of above-mentioned Binder for Colored Pavement, comprises the following steps:
1) in reactor, add the molten state waste or used plastics mixed liquor of set amount；
2) reactor it is warming up to 220 DEG C and opens stirring, and being sequentially added into modifying agent and plasticizer when speed of agitator is 110r/min；
3) be again warming up to 230 ~ 240 DEG C and use cutter when shearing rotating speed 3500 ~ 3800r/min to step 2) mixture of gained shears 4h；
4) it is sequentially added into age resistor and ultra-violet protecting agent to the mixture in step 3), and continues stirring 1h when speed of agitator is 110r/min；
5) mixture of step 4) gained is passed through cooling tower so that it is temperature drops to 100 ± 10 DEG C；
6) by the mixture of step 5) gained by double screw extruder extruding pelletization, thus obtaining the granule of finished product Binder for Colored Pavement.
For solving above-mentioned technical problem, another technical solution used in the present invention is: the preparation method providing a kind of above-mentioned colored road surface compound, comprises the following steps:
1) on request required aggregate being dried, drying temperature is 180 ~ 200 DEG C；Aggregate after drying is sieved by grating；
2) weigh hot aggregate, coloring agent, breeze and polyacrylonitrile fibre by weight some, and mix mix 90s；Wherein, hot aggregate is the aggregate of gained after step 1) screening；
3) when 160 ~ 200 DEG C to step 2) mixture in continuously add Binder for Colored Pavement mix 90s, obtain colored road surface compound.
The invention has the beneficial effects as follows: be different from the situation of prior art, the present invention utilizes the waste or used plastics such as PE, PP, PVC, PET, ABS to prepare molten state waste or used plastics mixed liquor, and under condition of different temperatures, in mixed liquor, it is sequentially added into modifying agent, synthesis plasticizer, age resistor and ultra-violet protecting agent, again through techniques such as cooling, pelletizes, obtain Binder for Colored Pavement.The Binder for Colored Pavement of the present invention has that less costly, preparation technology is simple and the feature such as stable performance, can meet the pavement performance requirement of high grade pavement.
