Description
Technical field
The present invention relates to the preparation method of a kind of bituminous preparation method's, particularly a kind of heatproof modified pavement asphalt.
Technical background
In highroad, bituminous pavement occupies critical role.Bituminous pavement is smooth, wear-resisting, airborne dust, waterproof, and durable not, and in addition, bituminous pavement has bullet one a sticking plasticity, when automobile when running at high speed, shake little, noise is little, and is slightly flexible, steady, comfortable.But pitch belongs to paraffin wax base crude oil more, and it is higher that it contains cured amount, can reduce asphalt high-temperature viscosity, low-temperature ductility, cohesiveness and plasticity owing to cured, also has higher thermo-sensitivity simultaneously; Thereby make the pitch can not film forming, and bad adhesion, easily aging, bituminous pavement is easy to generate gathers around bag, crack, phenomenon such as loose.Therefore carry out modification to containing the high pitch of cured amount, Nuo Feierte (NOVOPHALT) modified asphalt technology as the polyethylene modified asphalt of Austrian Richard Fil company of Singh global group, utilize the thermoplasticity of properties-correcting agent, infiltrating to stir in the heated bitumen makes properties-correcting agent softening, and polyethylene is dispersed in the pitch by the powerful shearing action of colloidal mill, be made into modifying asphalt through repeatedly circulating and turning the colloidal mill gap gradually down, dissolving property, complex process, need the specific equipment mechanically modifying, the cost height, asphalt high-temperature viscosity, low-temperature ductility, plasticity, cohesiveness still is relatively poor.
Summary of the invention
The objective of the invention is to adopt a kind of properties-correcting agent all is dissolved in the pitch, technology is simple, and cost is low, does not need specific equipment, the preparation method of the modified pavement asphalt of bituminous high temperature viscosity, low-temperature ductility, plasticity, heatproof that cohesiveness is good.
The object of the present invention is achieved like this, and a kind of preparation method of modified pavement asphalt of heatproof is as follows:
A) preparation degraded macromolecular modifier:
By weight with 10% Stockholm tar, 1% phenylic acid, 0.8% scorch retarder, 1% thermo-stabilizer, 88.2% granularity is that 10 purpose waste rubber powders are put into reactor simultaneously, be warming up to 180-200 ℃, be incubated 2 hours, be warming up to 260-280 ℃ after waste rubber powder is softening, be incubated 2 hours, after treating that waste rubber powder is degraded into liquid, the granularity that is cooled to 200 ℃ of addings 15% is 10 purpose synthetic resin moulding compounds, the dispersion agent W33 of adding 1.1% and 0.3% CBS promotor when synthetic resin moulding compound is degraded into liquid, polyreaction is carried out in 180 ℃ of insulations, and it is standby to take the dish out of the pot after 40 minutes;
B) preparation matrix pitch:
Petroleum residual oil is put into the fat jar of taking back the stream device, when being warming up to 150 ℃, pressing 0.8KPa and feed pressurized air stirring 30 minutes, warming while stirring is warming up to 260-270 ℃, is incubated 3 hours and makes matrix pitch;
C) allotment modification:
By weight the matrix pitch of 95-80% preparation is put into the fat jar, be warming up to 180 ℃, the degraded macromolecular modifier that adds the 5-20% preparation stirs and is warming up to 200 ℃ of insulations 10 minutes, dissolving, fatization, the modified pavement asphalt that aggregates into heatproof and harvesting.
Thermo-stabilizer is that the high valent acid vegetable oil by weight 98% is put into vulcanizing pan, adds 2% sulphur, is warming up to 200 ℃ and vulcanizes the vulcanized vegetable oil that makes.
Regnerated rubber powder is that the Tire ﹠ Tube with junked tire is ground into granularity 10 orders through pulverizer.
Synthetic resin moulding compound be with in polystyrene or polyvinyl chloride or the vinyon waste one or more through clean, remove dirt, foreign material after, be ground into granularity 10 orders through pulverizer.
Petroleum residual oil among the present invention adopts the CHS0356-92 standard of pressing, major ingredient asphaltenes 23.58%, resinous material 26.6%, oil content 46.69%, wax 5.45%, each big oil refinery station-service decompression, normal pressure or cracking technology carry out surplus materials after the petroleum refining to petroleum crude oil, at high temperature send into pressurized air it is carried out ultrasonic stirring and oxygenation with air compressor machine, forming the oxygenation dewaxing carries out simultaneously, make petroleum residual oil generate resinous material from oil, the bitum process of regeneration makes matrix pitch.Add the degraded macromolecular modifier that is made by rubber powder and synthetic resin moulding compound, Stockholm tar and allocate modification in matrix pitch under promoter effect, high temperature dissolving down, fatization, polymerization make the modified pavement asphalt of heatproof.Rubber powder in the properties-correcting agent, synthetic resin moulding compound can improve bituminous low-temperature ductility, winter hardiness, thermotolerance, cohesiveness and gas tightness, and CBS promotor promotes fatization.Dispersion agent W33 (dispersing agentWW33), Chemical Composition is the mixture of polymer natural acid, fatty acid ester and fatty acid soaps, physico-chemical property is the beige sheet, the aromatic hydrocarbon smell.Scorch retarder is from U.S.'s import, CA accession number 135-57-9.Stockholm tar has another name called wood pitch, buys on the market.Phenylic acid adopts Chongqing Organic Chemical Plant to produce industrial phenol.Feed pressurized air in the preparation process and form ultrasonic stirring on the one hand, make its dissolving evenly, pressurized air contains aerobic on the one hand, and promptly oxygenation improves pitch softening point in pitch.Press the modified pavement asphalt of the heatproof of the present invention's preparation, wax content has only 0.3%, detect by the JTJ036-98 standard SBRH-A promulgated by the ministries or commissions of the Central Government of China the Ministry of Communications～B, (25 ℃ of penetration degrees, 0.1mm) be 83, ductility (5cm/min, 25 ℃)＞100, softening temperature (ring and ball method) is 60-65, is higher than the Ministry of Communications's ministerial standard.
Press the preparation method of the modified pavement asphalt of heatproof provided by the invention, do not need specific equipment, technology is simple, reduce production costs, properties-correcting agent all is dissolved in the pitch, and pitch has more elasticity, plasticity, cohesiveness, high temperature is no lack of oil, and low-temperature ductility is good, aging, crack, not loose not.
