The asphalt regenerant is prepared from the waste edible oil, a plasticizing agent, a stabilizer and an age resister through mixing, wherein the contents of the components in percentages by weight are as follows: the waste edible oil 85%-95%, the plasticizing agent 2%-5%, the stabilizer 2%-5% and the age resistor 1%-5%. The asphalt regenerant prepared by utilizing the waste edible oil and the preparing process of the asphalt regenerant, disclosed by the invention, have the advantages as follows: 1, the preparing process is simple, low in cost and easy to implement; 2, as the preparing process adopts the waste edible oil as the main raw material, the reuse problem of the waste edible oil is solved efficiently and the waste edible oil is avoided appearing on dinner tables again to endanger people's health; and 3, due to the asphalt regenerant, waste asphalt is ensured to be recycled, and petroleum resources can be saved efficiently.
Description
Technical field
The waste that the invention belongs in the environmental protection field utilizes the field again, is specifically related to a kind of bitumen regenerant and preparation technology thereof who utilizes the waste edible oil preparation.
Background technology
China's sewer oil incident takes place frequently in recent years, and it is physically and mentally healthy that people in serious harm, has caused that the whole society pays close attention to.All kinds of poor quality oils in the sewer oil general reference people life, its staple remains triglyceride level, but Duo many pathogenic, carcinogenic toxicants than edible oil, is a kind of strong carcinogen like its main harm thing flavacin, and its toxicity is 100 times of arsenic.Sewer oil contains toxin, flows to rivers and can cause water nutritionization, and long-term edible meeting cause obvious injury to human body, like dysplasia, easy trouble enteritis, and liver, the heart and pathologies such as kidney enlargement and fatty liver is arranged.China is that the administrative mechanism also lack system perfecting is reclaimed in the processing of waste edible oil to the sewer oil raw material, and the optimum method that solves " sewer oil " backflow dining table is exactly to its raw material--waste edible oil fully utilizes.
For existing pertinent literature of the utilization of waste edible oil and patent; Chinese patent 200610019418.2 " utilizes the technology of propagation waste oil production biofuel " provides a kind of under the effect of normal temperature and pressure and catalyzer; Accomplished esterification in 4-8 hour, and esterification yield reaches 96% the technology of utilizing propagation waste oil production biofuel.It is raw material that Chinese patent 200710020438.6 " method for preparing epoxy plasticizer with sewer oil and waste oils and fats " proposes with sewer oil and waste oils and fats; Adopt gas-phase methanol and grease to carry out esterification; Adopt the catalyzer of the solid acid of porous support as esterification; The fatty acid methyl ester that obtains can reach 97%, and is equipped with epoxy grease plasticizer with ydrogen peroxide 50 as the oxygen supply system.But these technical finesse costs are high, also do not form industrialization in China.Therefore, seeking that a kind of amount of dissolving is big, the simple waste edible oil method of comprehensive utilization of technology, is to stop the best measure that waste edible oil gets into edible field again from the source.
Summary of the invention
Technical problem to be solved by this invention is that a kind of bitumen regenerant and preparation technology thereof who utilizes the waste edible oil preparation is provided to above-mentioned prior art; Its preparation technology is simple; The gained bitumen regenerant effectively reduces the softening temperature and the viscosity of waste asphalt, improves penetration degree and ductility.
The present invention solves the problems of the technologies described above the technical scheme of being taked: the bitumen regenerant that utilizes the waste edible oil preparation; It is formed through mixed preparing by waste edible oil, softening agent, stablizer and inhibitor; Each component concentration is by weight percentage: waste edible oil 85% ~ 95%; Softening agent 2% ~ 5%, stablizer 2% ~ 5%, inhibitor 1% ~ 5%.
Press such scheme, said waste edible oil is edible oil that reclaims or the frying oil that uses repeatedly, and moisture and volatile matter content amount wherein is not more than 0.2%, and acid number is not more than 0.50mgKOH/g.
Press such scheme, said softening agent is a butyl phthalate.
Press such scheme, said stablizer is one or both proportionings mixture arbitrarily in Sasobit and the sulphur.
Press such scheme, said inhibitor is one or both proportionings mixture arbitrarily in polynite and the wilkinite.
Utilize the preparation technology of the bitumen regenerant of waste edible oil preparation, it is characterized in that including following steps:
1) by each raw material weight per-cent: waste edible oil 85% ~ 95%, softening agent 2% ~ 5%, stablizer 2% ~ 5%, inhibitor 1% ~ 5%, it is subsequent use to choose waste edible oil, softening agent, stablizer, inhibitor;
2) waste edible oil of step 1) being got is poured in the container, is heated to 120 ℃ ~ 140 ℃, under this temperature, adds softening agent, stablizer and inhibitor successively, stirs 20 ~ 40 minutes to evenly, promptly gets bitumen regenerant after the cooling.
Press such scheme, said waste edible oil is edible oil that reclaims or the frying oil that uses repeatedly, and moisture and volatile matter content amount wherein is not more than 0.2%, and acid number is not more than 0.50mgKOH/g.
Press such scheme, said softening agent is a butyl phthalate.
Press such scheme, said stablizer is one or both proportionings mixture arbitrarily in Sasobit and the sulphur.
Press such scheme, said inhibitor is one or both proportionings mixture arbitrarily in polynite and the wilkinite.
Ultimate principle of the present invention is: the staple of waste edible oil is the ester class, be similar to the light component in the asphalt component, and pitch light component in weathering process transforms to heavy component." component is regulated theoretical " according to asphalt-regenerating; Bituminous regeneration is exactly the LV oil plant that in aged asphalt, adds certain component; The material that perhaps adds d spiss is allocated, and makes the regeneration asphalt after the allotment have suitable viscosity and required pavement performance, to satisfy the road with requiring.Waste edible oil is added the component that can regulate in the aged asphalt in the pitch form, add some admixtures simultaneously, finally make aged asphalt reach new bituminous performance level.
The bitumen regenerant of the present invention's preparation can make each item performance of waste asphalt all be significantly improved, and can effectively reduce the softening temperature and the viscosity of waste asphalt, improves penetration degree and ductility, and each item performance index lasting stability.The present invention has following useful fruit:
1, this method technology is simple, cost is low, be prone to enforcement;
2, this method is main raw material with the waste edible oil, and what efficiently solve waste edible oil utilizes problem again, has avoided waste edible oil to get into dining table once more, harm people's health;
3, this bitumen regenerant can make waste asphalt be reused, and can effectively practice thrift petroleum resources.
