Abstract
The present invention relates to a waste asphalt regenerating agent which belongs to the technical field of preparing auxiliary materials for processing asphalt. The waste asphalt regenerating agent comprises light oil, resin, anti-ageing agent, ultraviolet ray resisting auxiliary agent, etc. The waste asphalt regenerating agent is characterized in that all the components respectively have the following weight percentage: 75 to 90% of light oil, 10 to 25% of resin, 0.1 to 1% of anti-ageing agent and 0.1 to 1% of ultraviolet ray resisting auxiliary agent. Aiming at the characteristics of aged waste asphalt materials in asphalt pavements, the resin, the anti-ageing agents, the ultraviolet ray resisting auxiliary agents, etc. are added to the light oil in the waste asphalt regenerating agent, and materials of all the components are reasonably selected and compounded. The waste asphalt regenerating agent has obvious advantages and positive effects of easy obtainment of raw materials, low requirement for preparation equipment, simple preparation technology, low manufacture cost, convenient use, obvious regeneration effect, rapid effect taking, lasting acting force, etc. Practical application shows that the waste asphalt regenerating agent can make aged asphalt reach requirements of technical indices for original asphalt after being regenerated, and the service life of road surfaces paved by the regenerated waste asphalt is almost the same as new asphalt.
Description
Technical field
The present invention relates to a kind of pitch that gives up that can make and recover regenerant for waste asphalt of its use properties and preparation method thereof, belong to the manufacturing technology field of pitch processing with subsidiary material.
Background technology
Bituminous pavement with its driving steadily, not reflective, noise is low, dust is little, maintenance is convenient, to traffic impact excellent properties such as less, on urban and suburban roads especially high-grade highway, be used widely.But along with the prolongation of duration of service, multiple pathology can take place in bituminous pavement under various load effects, makes bituminous pavement slowly change crisp, follow the string, harden gradually, crack, hole groove occur, until wearing out, produce be full of cracks.
Existing maintenance of surface technology is mainly repairs renovation and pavement recycling maintenance, repairing renovation promptly lays again with new modifying asphalt, a large amount of waste materials of Chan Shenging are discarded as meeting with therefrom, can cause a large amount of environmental pollutions on the one hand, cause wasting of a large amount of bituminous materials on the other hand again; The pavement recycling maintenance then adopts regenerator to mix in the useless pitch, makes pitch soften, dissolve each other.Existing Imported Asphalt regenerator restricts its applying of market at home owing to its complicated component, cost an arm and a leg; And lightweight oil that the home-made regenerator mainly is some petroleum industries to be produced such as lubricating oil, diesel oil, machine oil etc. or their mixture, be used for the old material of modification, but because composition is single, regeneration effect is unsatisfactory, a certain amount of new pitch must be in old pitch, mixed, the service requirements of high grade pavement could be satisfied.
Summary of the invention
The object of the present invention is to provide a kind of old asphalt waste effective regeneration and can delay its aged regenerant for waste asphalt and preparation method thereof once more greatly of making.
The present invention is a regenerant for waste asphalt, comprises the lightweight oil content, resin, anti-aging agent and uvioresistant auxiliary agent is characterized in that the composition of each component is respectively by weight percentage: lightweight oil content 75-90%, resin 10-25%, anti-aging agent 0.1-1%, uvioresistant auxiliary agent 0.1-1%; Described lightweight oil is divided into furfural oil, lubricating oil, the mixture of any one or more of Semen Maydis oil; Described resin is resin or the petroleum resin that extract in the tar.
The lightweight oil content plays permeate agent and solubilizing agent in bitumen regenerant; The main effect of resin is absorption and stable lightweight oil content, and the component in lightweight oil content and the useless pitch of aged forms a kind of stable macromolecular solution system again.
Described anti-aging agent can be 6-oxyethyl group-2,2,4-trimethylammonium-1,2-dihyaroquinoline; 2,2,4-trimethylammonium 1,2-dihydro quinoline polymer; N-phenyl-α-aniline; The N-Phenyl beta naphthylamine; N-phenyl-N`-cyclohexyl Ursol D; 2, the mixture of one or more of 6-di-t-butyl-4 methylphenol etc., it mainly acts on is to prevent regeneration asphalt (mainly being the effect of oxygen) each component aging once more under extraneous Conditioning.
Described uvioresistant auxiliary agent can be 2,4-dihydroxy benaophenonel or 2-hydroxyl-4-methoxy benzophenone, and it mainly acts on is to absorb ultraviolet ray, delays the aging once more of regeneration asphalt.
The preparation method of regenerant for waste asphalt of the present invention is:
By weight percentage, under whipped state, the lightweight oil content is heated to 100-120 ℃, resin is dropped in the above-mentioned lightweight oil content, under 100-120 ℃ of state, stir 25-60min, after dropping into anti-aging agent and uvioresistant auxiliary agent when naturally cooling to 60-80 ℃, continuing to stir 25-60min, be cooled to and obtain the heavy-gravity liquid form mixt under the normal temperature and be regenerant for waste asphalt of the present invention.
The using method of product of the present invention is, the pitch that will give up is warming up to 120-150 ℃, the ratio of regenerant for waste asphalt of the present invention in the 3%-15% of useless pitch weight joined in the useless pitch, through being stirred well to the regenerant for waste asphalt thorough mixing in useless pitch, pitch after gained pitch is and is reproduced, its technical indicator of regeneration asphalt of handling through regenerant for waste asphalt of the present invention reaches the requirement that petroleum pitch technical requirements JTJ 032-94 heavily hands in the Ministry of Communications.
The present invention is directed to the useless bituminous material characteristic of aged in the bituminous pavement, by in the lightweight oil content, adding resin, anti-aging agent, uvioresistant auxiliary agent etc., and the each component material carried out choose reasonable and proportioning, have that starting material are easy to get, prepare that equipment requirements is low, preparation technology is simple, low cost of manufacture, easy to use, outstanding advantage and positively effect such as regeneration effect is obvious, and rapid-action, reactive force is lasting.Through practical application, regenerant for waste asphalt of the present invention can make the useless pitch of aged reach the protobitumen technical requirement after regeneration, and it paves, and working life is basic identical with new pitch, can also delay it greatly and wear out once more.
