Abstract
The road sealing material consists of asphalt as basic material 30-75 wt%, SBS 3.0-12.0 wt%, SBR 1.0-5.0 wt%, EVA 1.0-4.0 wt%, PE 0.5-3.0 wt%, petroleum resin 0-5.0 wt%, lime powder 5-20 wt% and talcum powder 5-25 wt%. The road sealing material of the present invention has excellent performance of being stable at high temperature and anticracking at low temperature, wide elasticity and plasticity range, high stability, wide tolerant temperature range, high adhesion to original asphalt road, no harm to human body, no environmental pollution, low cost and other advantages.
Description
Technical field
The present invention relates to chemical that a kind of road seam uses and preparation method thereof, more specifically say so and utilize high molecular polymer pitch to be carried out modification, add other ancillary additions simultaneously, produce road sealing material as main properties-correcting agent.
Background technology
Continuous increase along with China's traffic route quantity and mileage, continuing to increase of vehicle flowrate, the maintenance on road surface, maintenance service are heavy day by day, also seem very important, and the seam on traffic road surface is an important content of road surface maintenance service, and the height of pavement joint quality directly has influence on the quality on traffic road surface, and then influences traffic safety and convenient, therefore the quality of road sealing crack stopping has become an important factor that guarantees the normal use in road surface.
At present, the road sealing seam sealer that China uses, as Chinese patent literature 02109424.1 disclosed a kind of sealing adhesive for crack on road, it comprises petroleum pitch, SBS, tackifying resin, development of anti stripping agent for asphalt, rubber antioxidant and toluene, has following prescription: petroleum pitch: 60%-85%, SBS:5%-20%, tackifying resin 5%-20%, development of anti stripping agent for asphalt: 0.1%-4%, rubber antioxidant: 0.2%-1.4%, toluene: 10%-30% (above prescription all by weight 100%).Because this material uses toluene to make solvent, easily human body is worked the mischief and problem such as contaminate environment, and elasticity, weathering resistance, adhesive property are not high.
Summary of the invention
Technical problem to be solved by this invention is to overcome the above-mentioned defective of prior art and a kind of road sealing material and preparation method thereof is provided, the asphaltic base road sealing material that it obtains has snappiness, high-weatherability, high-adhesion energy, can be used for the seam of road under the repairing of motorway and the contour service requirements of airport cement pavement.
The present invention solves the problems of the technologies described above the technical scheme that is adopted:
A kind of road sealing material, by matrix pitch, main properties-correcting agent, supplementary additive and stopping composition are formed.
Above-mentioned matrix pitch is a heavy traffic paving asphalt, main properties-correcting agent is styrene-butadiene-styrene block copolymer (SBS), styrene-butadiene rubber(SBR) (SBR) and ethene-vinyl acetate-vinyl chloride graft copolymer (EVA) high molecular polymer, supplementary additive is polyethylene (PE) and petroleum resin, and stopping composition is lime powder and talcum powder.
Concrete, road sealing material, (weight percent) composed of the following components:
Matrix pitch: 30-75%;
SBS 3.0-12.0％；
SBR 1.0-5.0％；
EVA 1.0-4.0％；
PE 0.5-3.0％；
Petroleum resin 1.0-5.0%;
Lime powder 5-20%;
Talcum powder 5-25%.
Above-mentioned matrix pitch is a heavy traffic paving asphalt.
The preparation method of above-mentioned road sealing material is: matrix pitch is heated to 180～210 ℃, under this temperature, SBS, SBR and EVA master's properties-correcting agent joined in the matrix pitch and stir, up to fusion fully, add supplementary additive polyethylene (PE) and petroleum resin then and continue to stir fusion, add weighting agent lime powder and talcum powder at last, obtain road sealing material after stirring.
Compared with prior art, the invention has the advantages that:
1, road sealing material of the present invention is mainly by heavy traffic petroleum pitch and high molecular polymer is composite forms, premium properties with high-temperature stable, anti-low-temperature cracking, and elasticity and plastic zone are bigger, and can guarantee has satisfactory stability behind the crack construction, summer is outer moves, winter embrittlement cracking not; Big, the long service life of tolerance warm area has good cohesiveness with original bituminous pavement, is a kind of road sealing material of high comprehensive performance.
2, road sealing material of the present invention is owing to adopt heavy traffic asphaltum as base-material, so the component convenient sources, and production cost is low, low price.
3, road sealing material of the present invention does not have to adopt organic solvent commonly used, therefore can not work the mischief to human body, can not pollute environment yet.
4, preparation method of the present invention is simple, adopts existing processes equipment just can manufacture a product, and etching apparatus does not produce " three wastes ".
Road sealing material of the present invention has been applied to Turfan-Urumchi, Xinjiang-express highway pavement crack, Dahuangshan and has repaired.Driving through a nearly summer, a winter is used, and the fracture faces of repairing is functional, phenomenons such as no high temperature trickling, cold cracking.
Embodiment
Below in conjunction with embodiment the present invention is described in further detail.
Embodiment 1-5
In having the container of agitator, the Kelamayi petro-chemical corporation heavy duty road asphalt (70#, 90# or 110#) that adds the different trades mark by the amount of determining among the embodiment, be heated to 180～210 ℃, under this temperature, SBS (YH791 of Yueyang petrochemical industry), the SBR (the SBR rubber powder of Shandong Gao Shi scientific ﹠ trading Co., Ltd.) and the EVA that add respective amount stir fusion, the fusion back adds PE (petro-chemical corporation ethylene plant, Dushanzi) and petroleum resin fully, and the fusion back adds true quantitative lime powder Ca (OH)
2And talcum powder, stir evenly and promptly get road sealing material.
Seam sealer is formed and gained seam sealer product property sees Table 1, table 2.
