Description
Technical field
The present invention relates to a kind of Colophonium, be specifically related to a kind of SBS modified pitch and preparation method thereof.
Background technology
In civil engineering, Colophonium is widely used waterproof material and anti-corrosion material, be mainly used in roofing, ground, underground structure waterproof, timber, the anticorrosion of steel.Widely used pavement structure cementing material in Colophonium or road engineering, it can build up the bituminous paving of different structure from the mineral nitrogen material of different compositions after proportioning, application in highways is relatively broad.
Existing Colophonium processing technology is relatively simple, there is poor-performing, easily feels like jelly summer, the defects such as winter is the most dry and cracked.
The Colophonium that matrix pitch i.e. extract from oil or coal.Existing matrix pitch material temperature poor stability, easily isolates in transportation, the road surface easy embrittlement in winter laid with it, easily softens summer；The mixture gap rate of compacting is big, and poor water resistance is easily generated Water Damage；Matrix pitch is macromolecular material, and resistance to ag(e)ing is poor, and durability is difficult to ensure；The retentivity of flatness is poor, and not only sedimentation makes flatness deteriorate, and material softening is easily formed rut.
Summary of the invention
It is an object of the invention to provide a kind of SBS modified pitch and preparation method thereof, solve existing manufacture method and make and go out Colophonium, there is poor-performing, easily feel like jelly summer, the problem that winter is the most dry and cracked.
A kind of SBS modified pitch, the stabilizer of the SBS modifier of matrix pitch, 4～6%, 0.1～0.4% including 88.6%～94.9% and the aromatic naphtha of 1%～5%, wherein said stabilizer is to be configured by TMTD accelerator and Cosan to form.
More detailed proportioning, can be the described SBS modified pitch matrix pitch, the SBS modifier of 5%, the stabilizer of 0.2% and the aromatic naphtha of 3% that include 91.8%.
Further, described matrix pitch is 70#A type Colophonium.
Further, described stabilizer is to be formed with the proportional arrangement of 2:1 by TMTD accelerator and Cosan.
The manufacture method of a kind of SBS modified pitch, comprises the following steps:
Step one, is delivered to high-temperature tank by the matrix pitch of 88.6%～94.9% and heats, and is heated to 175 DEG C～185 DEG C；
Step 2, adds the matrix pitch being in 175 DEG C～185 DEG C temperature and produces tank, be simultaneously introduced the SBS modifier of 4～6%, is stirred mixing, and stirring incorporation time was at 1～2 hour；
Step 3, makes it fully dissolve by grinding machine the Colophonium being stirred；
Step 4, the Colophonium fully dissolved loads finished pot, and adds 0.1～the stabilizer of 0.4% and the aromatic naphtha of 1%～5% in finished pot, is again stirring for mixing and breeds 1～2 hour, it is thus achieved that SBS modified pitch.
In the manufacture method of this SBS modified pitch, more detailed step is as follows:
Step one, is delivered to high-temperature tank by the matrix pitch of 93% and heats, and is heated to 180 DEG C；
Step 2, adds the matrix pitch being in 180 DEG C of temperature and produces tank, be simultaneously introduced the SBS modifier of 4.5%, is stirred mixing, and stirring incorporation time was at 1～2 hour；
Step 3, makes it fully dissolve by grinding machine the Colophonium being stirred；
Step 4, the Colophonium fully dissolved loading finished pot, and in finished pot, add stabilizer and the aromatic naphtha of 2.2% of 0.3%, it is again stirring for mixing and breeds 1～2 hour, it is thus achieved that SBS modified pitch.
Further, described stabilizer is to be formed with the proportional arrangement of 2:1 by TMTD accelerator and Cosan.
Compared with prior art, the invention has the beneficial effects as follows: on original base, add aromatic naphtha.High temperature resistant, antiinflammatory is trembled with fear, and improves service life, compares environmental protection.
On this SBS modified pitch original base, add aromatic naphtha, can have the most high temperature resistant in the region that the temperature difference is bigger, anti-seismic design；There is preferable rutting resistance, its elastic and good toughness；Improve the anti-fatigue ability on road surface, particularly on big flow, the serious highway that overloads, there is good adaptability to changes, the permanent deformation on road surface can be reduced.
Additionally being thoroughly mixed by modifying agent and matrix pitch in the manufacture method of SBS modified pitch, not only make Colophonium obtain homogenizing process with modified, and make the mutual tractive of strand of modifying agent, net distribution, improve the intensity of compound, enhance anti-fatigue ability.
