Technical field

The present invention relates to asphalt surface hot reproduction field more particularly to a kind of non-stones applied to heat regeneration asphalt concrete Oil base regenerative agent and preparation method thereof.

Background technique

It is overhauled, in reconstruction process in road every year, old material of asphalt pavement of the number in terms of ten million ton can be generated, again using pitch Raw technology road pavement old material carries out regeneration, will be the best approach for solving these old materials, the regeneration of traditional asphalt mixture It is that aged asphalt is softened by addition petroleum base regenerative agent, to achieve the purpose that reduction.

Petroleum base regenerative agent belongs to petroleum-type product, raw material because being light oil, this light oil nature wind, Highly volatile under the effects of heat, light, fragrance point therein are easy to happen oxidation, so this regenerative agent steady in a long-term cannot be deposited It is in pitch, the improvement to mixture performance is also an acts and efforts for expediency.And wherein contain asphalitine, colloid, also When former aged asphalt, improve pitch three norms scarce capacity, often up to less than also primary standard, especially bitumen ductility is even more and is difficult to Reduction；In hot recycling production and construction, due to regeneration the mixing time it is shorter, regenerative agent action time not enough, reducing power it is weaker The problems such as under, be unable to the old pitch of fast softening, cause regeneration after pavement quality cannot reach design standard, again with petroleum base Raw its own anti-aging property of the regenerated old asphalt mixture of agent is poor, causes its reclaimed bituminous pavement effective period of service shorter, Generally just become again aging using 2 years or so regenerated road surfaces.

And petroleum base regenerative agent raw material belong to lower layer's product caused by backward crude oil refining equipment, and in country Under the big situation of innovation and development, old refining equipment will necessarily be eliminated；Since Petroleum refining equipment continues to develop, a new generation Petroleum refining equipment the such auxiliary product of output, the auxiliary product of this lower layer will no longer will reduce increasingly；It is national in recent years Carry out the utilization of regeneration cycle class pavement material energetically, so the dosage of regenerative agent only can be in rising trend, this " for not answering Ask " form under, the product for developing a kind of alternative petroleum base regenerative agent is very urgent.

Non-petroleum base regenerative agent currently used for asphalt surface hot reproduction field is not yet seen in report.

Summary of the invention

In view of above-mentioned deficiencies of the prior art, a kind of non-petroleum applied to heat regeneration asphalt concrete provided by the invention Base regenerative agent and preparation method thereof, to substitute petroleum base regenerative agent.

In order to solve the above technical problems, technical solution of the present invention includes:

A kind of non-petroleum base regenerative agent applied to heat regeneration asphalt concrete, according to weight percent by following component Composition: the edible oil recovery after processing of 40%-80%, the matrix pitch of 10%-50%, 0.1%-5% stabilizer, The antioxidant of 0.1%-5%.

The non-petroleum base regenerative agent, wherein above-mentioned matrix pitch is No. 90 bi tumenf orr oads or No. 70 road stones One of oil asphalt.

The non-petroleum base regenerative agent, wherein above stabilizer is diaryl disulfide.

The non-petroleum base regenerative agent, wherein above-mentioned antioxidant is four [3- (3,5 di-t-butyl -4- hydroxyphenyl) third Acid] season amylalcohol rouge, one or both of three (2,4 di-tert-butyl-phenyl) phosphite esters mixture.

The non-petroleum base regenerative agent, wherein above-mentioned edible oil recovery after processing refers to that edible oil recovery passes through Dehydration, slagging-off, except color, de-taste technique, and obtained after colloid removes process.

The non-petroleum base regenerative agent, wherein above-mentioned colloid removal technique refers to through membrane separation process, aquation degumming One of method, acid degumming method, mould method for degumming method is handled, and the process of colloid in edible oil recovery is removed.

A kind of preparation method of above-mentioned non-petroleum base regenerative agent comprising following steps:

Will treated edible oil recovery according to being heated in weight percent investment reaction kettle, persistently stirred in heating process It mixes, when edible recycling oil temperature rises to 60 DEG C -130 DEG C, drips the matrix for being preheated to 80 DEG C -140 DEG C according to weight percent Blueness is uniformly added into reaction kettle and mixes with edible oil recovery, and constant temperature persistently stirs 10-30 minutes under the conditions of 60 DEG C -140 DEG C；

Then；Antioxidant is added into reaction kettle, constant temperature is uniform stirring 10-30 minutes under the conditions of 60 DEG C -140 DEG C Afterwards, by weight percentage add stabilizer, continue constant temperature under the conditions of 60 DEG C -140 DEG C uniform stirring merge 50 minutes -100 points Zhong Hou is gradually cooling to room temperature, finally obtains the non-petroleum base regenerative agent.

The preparation method, wherein above-mentioned room temperature is 25 DEG C.

The preparation method, wherein above-mentioned edible oil recovery after processing refers to edible oil recovery by being dehydrated, removing Slag, except color, de-taste technique, and obtained after colloid removes process.

The preparation method, wherein above-mentioned colloid removal technique refers to through membrane separation process, aquation method for degumming, acid refining One of method for degumming, mould method for degumming method is handled, and the process of colloid in edible oil recovery is removed.

The non-petroleum base regenerative agent and preparation method thereof that the present invention provides a kind of applied to heat regeneration asphalt concrete, this The non-petroleum base regenerative agent of invention can with the old pitch of fast softening, and under the conditions of mixing and stirring the in-situ heat regeneration short time, It can reach expected reduction effect, pitch three norms and asphalt physical index entirely reach specification and design after reduction It is required that the antioxidant added in non-petroleum base regenerative agent, can effectively control the oxidation of fragrance point, make fragrance point in pitch Steady in a long-term it can be present in pitch, to extend the service life of regenerated road surface, compared with conventional petroleum regenerative agent also proper energy Power promotes 50%, the performance after improving old pitch regeneration, and then under the premise of the service life of extension regenerated road surface, replaces For petroleum base regenerative agent.And oil recovery is eaten in the present invention by membrane separation process, aquation method for degumming, acid degumming method, mould The one of which Degumming method such as method for degumming, the colloid in grease is removed, obtains the stable raw material of performance, and its composition at Part restores pitch beneficial.Especially edible oil recovery is applied in aged asphalt regeneration techniques, eating oil recovery is to carry The synthesized form of body forms a kind of efficient non-petroleum base regenerative agent, not only reduces the consumption of petroleum-type non-renewable resources, It also solves edible oil recovery to be difficult to handle, perplexs the food safety and environmental issue of many years.
