High pitch and the adhesion strength at other interfaces.
Further, the propiodal that parts by weight of component is 0.05-0.1 parts is further included.
By using above-mentioned technical proposal, the expression activitiy of general chlorine is low, and substitution reaction is not so easily to carry out, and increases
Propiodal can increase the activity entirely reacted, and promote the progress of substitution reaction.
Further, the propiodal be sodium iodide or potassium iodide, or both mixture.
By using above-mentioned technical proposal, propiodal is provided by reaction of the mixture of sodium iodide or potassium iodide or both, from
And increase the activity entirely reacted, promote the progress of substitution reaction.
Further, the coupling agent is one kind in silane coupling agent, titanate coupling agent, phosphate coupling agent.
By using above-mentioned technical proposal, the R group and the polymer of Petropols, pitch and mineral aggregate etc. of coupling agent are anti-
Should, chemical bond is formed, the surface or interface of Petropols and pitch and mineral aggregate are linked up, increase the friendship between each polymer
Connection fusion, and improve the high-temperature behavior of pitch, temperature-sensitive performance and storage stability.
Further, the crosslinking agent is sulphur.
By using above-mentioned technical proposal, using sulphur as crosslinking agent, crosslinking is mutually bonded between each polymer molecule
The substance of structure is reticulated, the Residual carbon and temperature capability to pitch have very big promotion, while the compression strength of pitch also has
It dramatically increases.
Further, the chlorine substituent modifying agent includes chloracetyl chloride, chloropropanol ester and 4- chlorophthalimides
One or both of.
By using above-mentioned technical proposal, with one kind in chloracetyl chloride, chloropropanol ester and 4- chlorophthalimides
Or two kinds of conduct chlorine substituent modifying agent provide chlorine atom for polymer, improve the polarity of polymer, improve pitch and other objects
The compatibility of matter.
It is a further object of the present invention to provide a kind of chlorine substituent modified color pervious asphalt preparation method, including following step
Suddenly：
S1：Asphalt mixing is heated to simultaneously to melt, obtains asphalt mother liquid；
S2：Mineral aggregate, colored stone are added in asphalt mother liquid, continues to stir, heat simultaneously, obtain mixture A；
S3：Petropols, coupling agent and crosslinking agent are sequentially added in mixture A, is stirred, is heated simultaneously, obtain mixture B；
S4：Chlorine substituent modifying agent is added in mixture B, stirring heats, obtains colorful water-permeable pitch finished product simultaneously.
By using above-mentioned technical proposal, mixed again with mineral aggregate, colored stone etc. after pitch heating melting, and in heated condition
It is lower to be mixed evenly with Petropols, coupling agent and crosslinking agent, it is steady to improve the high-temperature behavior of pitch, temperature-sensitive performance and storage
It is qualitative, afterwards, chlorine substituent modifying agent is added in obtained mixture, further improves pitch and other materials
Compatibility.
Further, S4 ' is increased behind S3, before S4：Propiodal is added in mixture B.
By using above-mentioned technical proposal, accelerate the substitution reaction of chlorine substituent modifying agent and polymer using propiodal,
Promote the progress of chlorine substitution reaction.
Further, heating temperature is 130 DEG C -150 DEG C in S1.
By using above-mentioned technical proposal, by heating and temperature control in the range of this, can make pitch as early as possible melt and
Temperature can be avoided excessively high, the toxic and harmful gas in pitch is caused largely to volatilize, causes environmental pollution.
Further, heating temperature is 95 DEG C -100 DEG C in S4.
By using above-mentioned technical proposal, heating at such a temperature can promote the progress of chlorine substitution reaction, while can
The higher performance for making chlorine substituent modifying agent of temperature is avoided to be affected.
In conclusion the invention has the advantages that：
