Abstract
A polymer-modified asphalt is prepared through heating asphalt 100 portions to 140-210 deg.C, adding modifier 2-10 portions while stirring, adding stabilizer 0.1-2 portions and grinding. Its advantages are long storage period and polymer/asphalt homogenate.
Description
Technical field
The present invention relates to the production technique of traffic and production process of building materials, particularly polymer modified asphalt.
Background technology
Polymer modified asphalt is because of its good anti-rut, anti-heavy duty and high temperature performance, and in various countries' widespread use.Polymer modified asphalt generally can not be long time stored, therefore has only the employing situ production, and production efficiency is low, can not bring into play the throughput of equipment, and can only be in construction seasons production.
Summary of the invention
One of technical problem to be solved by this invention is: a kind of production technique of polymer modified asphalt is provided, and its technology is simple, and is easy to control, the modified asphalt technology excellent performance of producing, and thermmal storage is not stratified, and every index is stable, but long storage.
The present invention solves the problems of the technologies described above the technical scheme that is adopted:
The production technique of polymer modified asphalt is:
(1) 100 parts of pitches is warming up to the 140-210 degree;
(2) in the described pitch of step (1), add the properties-correcting agent of 2-20 part, and carry out agitation cycle;
(3) in the mixture of step (2), add 0.1-2 part stablizer;
(4) levigate finished product.
Properties-correcting agent melts in hard pitch, under the strong shearing action of homogenizer or colloidal mill, the properties-correcting agent refinement disperses, the physical crosslinking structure disappears substantially, under the function of stabilizer that adds, chemically crosslinked takes place between modifier molecules and pitch and the modifier molecules, make between the modifier molecules and modifier molecules and pitch between form the stable and stereoscopic reticulated structure, guaranteed properties-correcting agent uniform and stable distribution and avoid segregation in pitch effectively.
The present invention has solved the production technique of the modifying asphalt of anti-the storage effectively, when polymkeric substance in pitch fusion and be distributed to a certain degree after, adding can make the stablizer that crosslinked action takes place between polymkeric substance and pitch and the polymkeric substance, polymkeric substance is existed with metastable reticulated structure in pitch, to guarantee polymkeric substance uniform distribution in pitch, form polymkeric substance/pitch homogeneous phase body, be beneficial to long storage and do not emanate.
Specific embodiments
The specific embodiment of the production technique of polymer modified asphalt of the present invention is:
(1) with 1000 kilograms of 50-135
#Pitch is warming up to the 140-210 degree, and optimum temperuture is the 160-190 degree.
(2) in (1) described pitch, add 10 kilograms of properties-correcting agent, and carry out agitation cycle.
Properties-correcting agent can be styrene-butadiene-styrene block copolymer (SBS), styrene-ethylene/butylene-styrene block copolymer (SEBS), styrene isoprene styrene block copolymer (SIS) (SIS), styrene-ethylene/propylene-styrene segmented copolymer (SEPS), polyethylene (PE), polystyrene (PS), ethene-vinyl acetate (EVA), APAO etc.
(3) according to the consistency situation of pitch and used properties-correcting agent, can in the mixture of (2), add 5 kilograms expanding material, expanding material can be petroleum resin or mineral wet goods.
(4) mixture of the pitch/properties-correcting agent described in (2) is stirred in high-temperature tank add 1 kilogram of stablizer after 3 minutes to 24 hours, open homogenizer or colloidal mill simultaneously, properties-correcting agent and asphalt mixture process through homogenizer or colloidal mill the time is sheared and impact effect, refinement disperses rapidly, under function of stabilizer, produces the reversible chemical bond, polymkeric substance and pitch generation grafting, also be cross-linked with each other between the polymkeric substance, form uniform cubic network structure, the modifying asphalt that obtained performance is stable.
Stablizer can be 1, dimethyl disulfide; Or, the combination of 2,50% dimethyl disulfide, 35% sulphur, 15% metal oxide, metal oxide can be one or more the combination in magnesium oxide, calcium oxide, yellow lead oxide, zinc oxide and the tri-lead tetroxide.
(6) mixture in (5) is pumped into corresponding hold-up vessel, after 10 minutes to 4 hours, can pack and thermmal storage, for the usefulness of transportation with concrete.
