The pitch deposited and transported is very important.
Chinese invention patent discloses a kind of globular asphalt granulating device and prilling process, and the device of invention design is related to
One vertical shaft, shaft is driven by power device to be rotated, and lower end connects hemispherical centrifugation pot, passes through centrifugal rotational speed and raw material
Flow control particle size, granulation speed is fast, quality is good, however, it is very difficult to meet common heavy traffic paving asphalt or polymer modified asphalt
It is granulated.Chinese invention patent also discloses a kind of Hard asphalt granulation method and its device, and the invention is by the hard of molten condition
Pitch by distributing device with the uniform cloth of drop-wise revolution steel band on, revolution steel band below setting cool water shower to steel band cool down,
End isolates and falls off the particle of curing molding again, and simple process, operating cost are low, still, to low softening point, viscosity it is lesser
Pitch is not applicable.Chinese invention patent also discloses a kind of pitch pelletizer, which includes hopper, nozzle, cylindric granulation
Net, water cooling pond and scraper plate realize that pitch is granulated by cold water, and structure is simple, at low cost, still, are still difficult to meet common
Heavy traffic paving asphalt or polymer modified asphalt are granulated.
Summary of the invention
For this purpose, the embodiment of the present invention provides a kind of pitch and preparation method thereof that cast-type is granulated, to solve the prior art
The preparation process of middle pitch is complicated, safety is poor, at high cost and be difficult to meet common heavy traffic paving asphalt or polymer modified asphalt
The problem of granulation.
To achieve the goals above, embodiments of the present invention provide the following technical solutions:
A kind of pitch that cast-type is granulated, composition includes following each substances: casing material, interior core material, promotor, increasing are prolonged
Agent, plasticizer and adhesive, wherein the casing material be the casing material containing high softening point bitumen, the interior core material be containing
There is the interior core material of low softening point asphalt, the promotor is the promotor containing sulfenamide or thiurams;Containing thio
Agent is prolonged in the increasing of sodium sulphate or polycyclic aromatic hydrocarbon sodium sulfonate;The plasticizer is the plasticizer containing paraffin oil or retinal;The glue
Glutinous agent is the adhesive containing terpene resin or C 9 petroleum resin.
The weight that the casing material, interior core material, promotor, increasing prolong agent, plasticizer and adhesive is respectively as follows: institute
State casing material are as follows: 5~15 parts;The interior core material are as follows: 60~90 parts;The promotor are as follows: 0.01~0.5 part;Agent is prolonged in the increasing
Are as follows: 5~10 parts;The plasticizer are as follows: 0.5~2 part;The adhesive: 1~5 part.
The casing material is any one in high-quality pitch, No. 10 pitches or No. 30 pitches, and the high softening-point drips
Blueness is that softening point is higher than plain asphalt or polymer modified asphalt, and temperature is at 95 DEG C or more;The high-quality pitch contains for asphalitine
Amount is higher than the pitch of plain asphalt or polymer modified asphalt.
The interior core material is No. 70 pitches, the SBS of No. 90 pitches, No. 110 pitches, the SBS modified pitch of I-D, I-C are modified
Pitch, the SBS modified pitch of I-B, the SBS modified pitch of I-A, the SBR modified pitch of II-C, II-B SBR modified pitch or
Any one in the SBR modified pitch of II-A.
The promotor is one of sulfenamide type accelerators, thuriam acceserator or octadecanoid acid or any several
The mixture of kind.
It is in sodium thiosulfate, polycyclic aromatic hydrocarbon sodium sulfonate, sulphur sodium aluminate, triethanolamine or butyl stearic acid that agent is prolonged in the increasing
One or any of several mixture.
The plasticizer is one of paraffin oil, retinal or coal tar or any several mixture.
The adhesive is terpene resin, C 9 petroleum resin, coumarone indene resin, polyterpene resin or polyvinyl butyral
One of or any several mixture.
A kind of preparation method for the pitch that cast-type is granulated, comprising the following steps:
S1: casing material is subjected to pre- melt processed, and the temperature of pre- melt processed is 160~210 DEG C, and interior core material is carried out
Isothermal holding, and the temperature setting of isothermal holding is 100~160 DEG C;
S2: promotor is added in casing material and carries out mixed melting stirring, obtains the first mixture;
