Abstract
The purpose of the present invention is a kind of damaged tire thermal cracking carbon black asphalt modification additive of design, primary raw material of the carbon black as modified asphalt additive that thermal cracking generation is carried out with damaged tire, a certain proportion of polyethylene, SBS (styrene-isoprene-styrene), maleic anhydride, butadiene-styrene rubber, rubber oil, triethylene tetramine is sequentially added and stirred, form damaged tire thermal cracking carbon black asphalt modification additive, again respectively damaged tire thermal cracking carbon black asphalt modification additive, mixed after matrix pitch preheating, and shear agitation certain time at a certain temperature, i.e. generation is applied to the modified pitch that road surfacing is used.
Description
Technical field：
The invention belongs to asphalt modification additive technology field, the damaged tire that laying road matrix pitch is modified is especially suitable for
Thermal cracking carbon black asphalt modification additive.
Background technology：
In order to improve the quality of asphalt road, a certain proportion of additive is added in matrix pitch and is changed
Property, at present, the asphalt modification additive that tradition is used has thermoplastic elastomer class, rubber-like, resinae, and these modifying agent are although right
The performance of matrix pitch improves, but it is not enough to still suffer from poor low-temperature cracking-resistance, hot mastication, wearability and durability
Etc. defect.
The content of the invention：
The purpose of the present invention is a kind of damaged tire thermal cracking carbon black asphalt modification additive of design, carrying out heat with damaged tire
Primary raw material of the carbon black as modified asphalt additive of generation is cracked, a certain proportion of polyethylene, SBS (styrene-isoamyl
Styrene), maleic anhydride, butadiene-styrene rubber, rubber oil, triethylene tetramine sequentially add and stir, form damaged tire
Thermal cracking carbon black asphalt modification additive, then respectively damaged tire thermal cracking carbon black asphalt modification additive, matrix pitch preheating
After mix, and shear agitation certain time at a certain temperature, i.e. generation are applied to the modified pitch that road surfacing is used.
The present invention solve its technical problem used in technical scheme be in fact：Sieve of the damaged tire thermal cracking carbon black with 200 mesh
Net sieving, account for damaged tire thermal cracking carbon black asphalt modification additive mass ratio 65% damaged tire thermal cracking carbon black, 10%
Polyethylene, 8% SBS (styrene-isoprene-phenylethene), 3% maleic anhydride, 3% butadiene-styrene rubber, 5% rubber
Oil, 6% triethylene tetramine, which are sequentially added, is mixed and stirred for that uniformly, the damaged tire thermal cracking charcoal of modified pitch quality 17% will be accounted for
The preheating of albertite property-modifying additive is 100-110 DEG C, is 130-150 DEG C by 70# matrix pitches preheating temperature, and preheated is given up
Tire hot cracking black carbon asphalt modification additive is mixed with preheated 70# matrix pitches, and it is 130 that temperature is controlled in mixed process
DEG C, shearing mixing is carried out with cutter, mixer, when cutter, the rotating speed of mixer are 4000r/min, the shear agitation time
For 45/min；The shear agitation time is 90r/min when cutter, the rotating speed of mixer are 2500-3000r/min, that is, is generated suitable
The modified pitch used for road surfacing.
Beneficial effects of the present invention：
1, cost can be reduced by doing modified asphalt additive with damaged tire thermal cracking carbon black；
2, " rising occurs when can overcome laying road surface in the modified pitch being made of damaged tire thermal cracking carbon black asphalt modifier
The phenomenon such as bubble ", " pit ", improves the planarization on road surface, prevents road surface cold(ing)crack and hot mastication phenomenon；
3, the wearability and durability on road surface can be increased；
4, damaged tire belongs to the intractable pollutant of black solid, produces carbon black with damaged tire thermal cracking, does asphalt modification and add
Plus agent belongs to regenerated resource development and utilization, pollution can be reduced, is economized on resources.
Embodiment：
Step one：The damaged tire thermal cracking carbon black for needing Erbium-doped to enter damaged tire thermal cracking carbon black asphalt modification additive is used 200
Purpose screen cloth sieve, account for damaged tire thermal cracking carbon black asphalt modification additive mass ratio 65% damaged tire thermal cracking carbon black,
10% polyethylene, 8% SBS (styrene-isoprene-phenylethene), 3% maleic anhydride, 3% butadiene-styrene rubber, 5%
Rubber oil, 6% triethylene tetramine, which are sequentially added, to be mixed and stirred for uniformly,
Step 2：It is 100- that the damaged tire thermal cracking carbon black asphalt modification additive for accounting for modified pitch quality 17%, which is preheated,
110 DEG C, it is 130-150 DEG C by 70# matrix pitches preheating temperature, preheated damaged tire thermal cracking carbon black asphalt modification is added
Agent is mixed with preheated 70# matrix pitches, and it is 130 DEG C that temperature is controlled in mixed process, is sheared with cutter, mixer
Mix, when cutter, the rotating speed of mixer are 4000r/min, the shear agitation time is 45/min；Turn of cutter, mixer
The shear agitation time is 90r/min when speed is 2500-3000r/min, i.e. generation is applied to the modified pitch that road surfacing is used.
