Description
Technical field
This patent is related to a kind of bitumen for exploiting nature, be processed into can longer-term storage it is used for asphalt mixture into
The technique and formula of product cementitious matter.
Background technology
Bitumen is that the petroleum resources of nature act on high temperature, high pressure by the crustal movement of 1 years, oxidation, touched
Bitumen under the lower nature formed of the effect such as matchmaker, because bitumen is formed in the earth's crust, therefore in its component
In addition to bitumen, the mineral composition not waited containing 10%-80% also.Through XRF analysis find mineral matter it is main by Ca, Si, AL, Fe,
The elements such as S, K are constituted.Just because of the presence of mineral composition, bitumen shows excellent high-temperature stability, thus
Play important in the heavy-load road construction materials such as High Modulus Asphalt Mixture, Rut resistance ground surface material, pouring asphalt compound
Effect.But the relative density of mineral matter is more than 2, and pitch relative density is 1 or so, under the temperature in use of pitch（It is higher than
100℃）, pitch in liquid, if can not take mineral matter in effective technological means, bitumen will from pitch from
Analysis is precipitated out, the characteristics of not only losing bitumen, and easily silts storage tank up.
Existing traditional handicraft is that bitumen is crushed into 60 mesh, 100 mesh or 300 mesh or so, and input asphalt tank or pitch are mixed
Close and used in material mixing building.In all Patents that modified pitch is produced using bitumen as modifying agent, not to pitch
Storage stability make requirement and describe.When bitumen is direct plungeed into pitch, it is necessary to mixing plant be stirred continuously to prevent
Only precipitate, such as Chinese patent CN200720050884《A kind of improved natural asphalt stirring tank》.Chinese patent
201610896252.6《A kind of kir fluid fine grinding is modified hybrid technique》, bitumen shearing is ground to more than 150 mesh,
Index of the patent not pair with the glued later modified pitch of matrix pitch is analyzed.China Patent No. is
CN201310430663.2《A kind of plant oil modified bituminous composition and preparation method thereof》By add vegetable oil be used as it is natural
The dispersion of pitch obtains satisfactory road asphalt, and problems of stability in storage is not also referred to；And China Patent No. is
CN201620180136.X《Nanoscopic macromolecular bitumen grinder》The grinder invented by it is in 175-300 DEG C of temperature
The bitumen that particle diameter is 2 microns is obtained, but the patent only refers to a kind of breaking method of bitumen, how be not directed to should
The asphalt cementitious matter of finished product is produced with bitumen, and the performance change of the bitumen to producing is not carried out
Analysis.Stable being dispersed in how could be obtained the bitumen cementitious matter for meeting road occupation requirement is reached in pitch, these
Invention does not all provide clear and definite method and approach.
Caused by due to density issue in addition to storage stability problem, ductility loss is also bitumen modified pitch
Technological difficulties.Disperse uneven because bitumen mineral grain diameter of components is too big, and in pitch, and particulate matter causes
Stress concentration the problems such as the ductility of modified pitch is lost serious.Such as patent 03135742.3《A kind of road asphalt modifier
And preparation method thereof》By bitumen as asphalt modifier, bitumen addition reaches 15%, when 20%, modified pitch
15 DEG C of ductilities be more than 140cm by initial, reduce sharply 14.5cm, 8.5cm.In patent 200410021928.4, bitumen
15 DEG C of ductilities of modified pitch also decay it is more than half, and with the increasing particle size of bitumen product, decay aggravation.Patent
In 200410040424.7, by bitumen Task-size Controlling at 18 microns, under 5% addition, 15 DEG C of ductilities of pitch according to
So fall sharply.And asked in the patent as additive of other bitumens, or by SBS addition compensation ductility loss
Topic, or any requirement is not done to ductility.And the present invention can not only solve the storage sex chromosome mosaicism of bitumen, and produce
15 DEG C of ductilities of road asphalt are more than 100cm.
The content of the invention
In order to overcome the above-mentioned deficiencies of the prior art, it is an object of the invention to provide a kind of bitumen finished product cementitious matter
