Description
[technical field]
The present invention relates to a kind ofly be used for the composite modified master of asphalt modification and be used for modified asphalt preparation method.
[background technology]
Pitch is a kind of cheap and good-quality pavior, but bituminous material exists high temperature to trickle easily, and the easy rimose problem of low temperature in order to address these problems, to add macromolecular material usually pitch is carried out modification, improves the bituminous temperature sensitivity.Material commonly used mainly comprises butadiene-styrene thermoplastic elastomer (SBS), styrene-butadiene rubber(SBR) (SBR), ethylene-vinyl acetate copolymer (EVA), polyethylene (PE).The adding of these macromolecular materials can improve the bituminous temperature sensibility greatly, has improved the use properties of modifying asphalt.Usually SBS can improve the high low temperature use properties of modifying asphalt, and SBR mainly improves the low-temperature performance of modifying asphalt, and EVA and PE then mainly improve the high-temperature behavior of modifying asphalt.Present SBS is more extensive the application of modifying asphalt production field, and the method for modifying asphalt mainly comprises physically modified and chemical modification.Physically modified mainly is to be scattered in the pitch after by mechanical force macromolecular material being pulverized, because difference such as macromolecular material and bituminous molecular weight, polarity, viscosity are bigger, macromolecular material instability when stopping mechanical stirring, easily from pitch the come-up and separate, thereby the degradation that causes modifying asphalt, unstable properties, thus limited its range of application.Chemical modification is mainly by adding the chemical stabilizer of sulfur-bearing, itself and macromolecular material generation chemical reaction, simultaneously also with pitch in chemical ingredients have an effect, thereby macromolecular material is dispersed in the pitch, when the compatibleness of pitch and macromolecular material was good, the modifying asphalt of chemical modification had good high-temperature stability in storage and high low temperature use properties usually; But the problem that the chemical process modifying asphalt exists is exactly to produce to have toxic hydrogen sulfide in modifying process, and producers are had injury, produces environmental pollution.Along with the raising of International Crude Oil, cause the price of derived product such as SBS to increase substantially in recent years, the cost of modifying asphalt manufacturing enterprise also significantly improves thereupon, presses for to reduce cost.SBR is a kind of more satisfactory substitute.Many to the research of SBR modifying asphalt in the present domestic patent, the mode of the main in-situ processing that still adopts does not possess the good high-temperature stability in storage.The modifying asphalt for preparing by a certain percentage by petroleum pitch, styrene-butadiene rubber(SBR), solubility promoter, Polyolefin and sulphur that proposes as patent CN90106343.6.The composition and method of making the same that CN1597782A proposes with microwave exposure waste rubber powder modification highway asphalt.APAO, powder styrene butadiene rubber, the pitch blend that CN01135212.4 proposes prepares the method for modifying asphalt.It is the way that matrix is added powder styrene butadiene rubber, organo-metallic soap, rock asphalt ore deposit modifying asphalt that CN02139460.1 proposes with the higher pitch of wax content, and the method with FT paraffin, powder styrene butadiene rubber composite modified asphalt of the CN03129028.0 of Tongji University proposition.The wilkinite that CN200410069166.5 proposes, the method for powder styrene butadiene rubber composite modified asphalt.
[summary of the invention]
Purpose of the present invention is exactly in order to overcome high-temperature storage problem of unstable in the prior art, and the modifying asphalt of preparation has the good high-temperature stability in storage and possesses good anti-cold cracking, characteristics such as anti-aging.
For achieving the above object, the present invention proposes a kind of asphalt modification masterbatch, and basic powder styrene-butadiene rubber(SBR) (SBR), silicates inorganic stabilizers (mineral filler) are formed.
Above-mentioned asphalt modification masterbatch, described silicate inorganic stablizer are the composition of one or more inorganic stabilizers in wilkinite, illiteracy holder soil, the diatomite.Described powder styrene butadiene rubber weight content is 60-80%, and the weight content of silicate inorganic stablizer is 20%-40%.
The present invention proposes a kind of modified asphalt preparation method simultaneously, comprise the steps:
(1) preparation process of asphalt modification masterbatch: earlier powder styrene butadiene rubber, silicate inorganic stablizer are passed through Process Technology of Polymer equipment, make it be mixed to styrene-butadiene rubber(SBR) bag roller at 90-130 ℃, after the silicate inorganic stablizer is uniformly dispersed in powder styrene butadiene rubber, following sheet carries out granulation or pulverizing then;
(2) preparation process of modifying asphalt: it is in the matrix pitch of liquid that modified master drops into 120-160 ℃ of following fusion, adopt the high speed shear mixing equipment to shear, rotating speed 3500-4500 rev/min, sheared 3-50 minute, asphalt modification masterbatch polymer beads is dispersed in the pitch, prepares modifying asphalt.
Above-mentioned modified asphalt preparation method, in the described step (1), the powder styrene butadiene rubber weight content in the modified master is 60-80%, the weight content of silicate inorganic stablizer is 20%-40%.Described powder styrene butadiene rubber molecular weight ranges is 20000-50000.Described silicate inorganic stablizer is wilkinite, covers the composition of one or more inorganic stabilizers in holder soil, the diatomite that its particle size range is 300 orders-1200 orders.Polymer content is that the weight content in the modifying asphalt is 2-4% in the described asphalt modification masterbatch.
Above-mentioned modified asphalt preparation method, described Process Technology of Polymer equipment adopt Banbury mixer, mill,, described asphalt modification masterbatch processing temperature in described Process Technology of Polymer equipment is that 90-130 ℃, mixing time are 3-20 minute.Granulating equipment adopts dull and stereotyped dicing machine or pulverizer.Described high speed shear mixing equipment adopts high speed shear mulser or colloidal mill.Described modified master in described high speed shear mixing equipment 120-160 ℃ down cut 3-60 minute.
Owing to adopted above scheme, brought following beneficial effect:
After in pitch, adding powder styrene butadiene rubber, inorganic stabilizers modified master, when suitable inorganic stabilizers content, can make the stable modifying asphalt of high-temperature storage, and possess the good low-temperature performance.
Mesosilicic acid salt inorganic stabilizers of the present invention and powder styrene butadiene rubber carry out compound earlier, prepare the modified master of stable in properties, effectively increase the density of polymer composition, used this masterbatch to make modifying asphalt, effectively prevented the come-up separation phenomenon of polymkeric substance from pitch.Content by mineral filler in the telomerized polymer composition makes polymer composition reach stable effect.
Use modified master of the present invention, directly feed intake, pitch is carried out modification, need not field control throw in various modified materials, situ production technology is easy.
The modifying asphalt high-temperature storage that the present invention obtains is stable, and the modification cost is low, and production technique is easy, can be used for laying road, waterproof roll.
