Description
Technical field
The present invention relates to a kind of asphalts, and in particular to a kind of warm mixed epoxy bitumen mixture and preparation method thereof.
Background technology
With being continuously increased for highway mileage, highway bridge quantity also increases therewith.It is asked however, also exposing some
Topic, wherein being accounted for disease caused by the water-proof tack coat failure between bridge deck pavement and between pave-load layer and panel larger
Ratio causes attention of the people to bridge deck pavement material and technique.As bridge floor interlaminar bonding material, by adding in pitch
Add bituminous epoxy obtained from epoxy resin that there is preferable effect.However, the viscosity due to bituminous epoxy is larger, in construction
It is required that construction temperature is higher, also there is certain operable time, so increasing difficulty of construction；In addition, adding in pitch
After adding epoxy resin, pitch can be made to become fragile, flexibility is deteriorated, bad with the followability of bridge panel.In order to solve these problems,
Warm mix technology need to be taken to reduce the construction temperature of bituminous epoxy, and improve flexibility.
There are mainly three types of modes for warm-mixed asphalt technology：First, the higher emulsified asphalt of evaporated residue content is used, 80
DEG C~120 DEG C at a temperature of with building stones mix, which is about 30 DEG C~50 DEG C low compared with the temperature of hot asphalt；Second is that being mixed in mixing
Water when material（Or the aqueous solution of surfactant）It is added simultaneously in mix tank with pitch, due to the presence of water, makes asphalt foaming,
Reach viscosity reducing effect.But above two method will produce a large amount of vapor, easily causes equipment corrosion, stone also frequently occurs
Powder conglomeration even causes mixing equipment blockage problem, makes troubles to production.Further, since remaining non-volatile moisture is retained in
In mixture, mixture initial performance can be influenced.The third method is that warm-mixing agent is added in pitch in advance, then take with
The same mode of production of common hot-mix asphalt mixture, it is easy to operation, it is easy to be received by production unit.This kind of method passes through
Warm-mixing agent is added in pitch in advance, reduces the high temperature viscosity of pitch, changes the viscosity-temperature curve of pitch, to reduce drip
The green mix temperature with building stones reaches warm mix effect.But presently used warm-mixing agent leads to while reducing asphalt high-temperature viscosity
The reduction that often can also cause 60 DEG C of viscosity of pitch, makes the high-temperature stability of asphalt incur loss；Or on the contrary, not dropping
When low 60 DEG C of viscosity, the loss of pitch ductility can be caused, to reduce the cryogenic property of pitch.In short, presently used
Warm-mixing agent is while so that pitch is reached warm mix effect, is high-temperature behavior to lose pitch or cryogenic property as cost
's.
CN102443239A describes a kind of oil-resistant road asphalt modifier and preparation method thereof.The oil resistivity road drips
Green modifying agent includes 20~50 parts of styrene-ethylene/butylene-styrene block copolymer (SEBS), polyolefin tree by weight
10~30 parts of fat, 15~45 parts of macromolecule wax are rich in 10~30 parts of aromatic hydrocarbons tapped oil.Wherein macromolecule wax is Fischer-Tropsch wax, is rich in
Aromatic hydrocarbons tapped oil is furfural extract oil or phenol treating tapped oil.Preparation method is：Material is launched in proportion and arrives twin-screw
Oil-resistant road asphalt modifier is made in stretching and granulation in extruder, 120 DEG C~200 DEG C of extrusion temperature.The patent introduction it is resistance to
Oiliness asphalt modifier is to be developed for for the pitch used in the places such as parking lot, airplane parking area in order to improve its oil resistivity
A kind of modifying agent, for the warm mix effect of pitch, there is no enough attention, in the process of development, only with twin-screw
Extruder has carried out simple extrusion mixing, due to unsaturated bond limited amount on polymer molecule used, in Screw Extrusion
Only have a small amount of graft reaction in the process, enough chemical reactions does not occur, substantially a kind of simple physical mixed is right
It is very limited in the warm mix effect of pitch.
102061098 A of CN describe a kind of asphalt mixture warm-mixing modifier and preparation method thereof.It is by following masses
The composition of part is made, fischer-tropsch wax：50~85 parts, flexibilizing agent：15~50 parts, polyacid：0~10 part, synthetic resin：0~20
Part, petchem：0~5 part.Wherein, synthetic resin is polyisobutene of the molecular weight between 400~5000.Preparation method：
(1) each component is weighed in mass ratio；(2) each component is melted and is stirred at 120 DEG C~130 DEG C, be allowed to be sufficiently mixed
It is even to get the asphalt mixture warm-mixing modifier.In the warm-mixing agent development process, without sending out biochemical reaction between each component,
Only simple physical mixed.Although the mix temperature of pitch can be reduced, the ductility of pitch can incur loss i.e.
Asphalt is easy to happen cold cracking, causes asphalt thermal stability and low-temperature cracking-resistance bad, so that pitch is mixed
There is track and cracking and accelerates damage in solidifying soil surface face layer.
CN101735623A discloses a kind of warm mixed epoxy bitumen material and preparation method thereof, including component A and B component.A
Group is divided into epoxy resin, and B component includes pitch 40wt%~83wt%, maleic anhydride 5wt%~20wt%, 9- octadecenyl amines
10wt%~30wt%, poly sebacic polyanhydride or poly- azelaic acid acid anhydride 2wt%~10wt%；The mass ratio of component A and B component is 1:3~
5.8.Medium temperature mix can be used, reduce gas discharge when construction, while it is short to solve general bituminous epoxy operable time
Problem.But when preparing B component, maleic anhydride is added in pitch and needs stirring 4~6 hours, then also need to add
Add other components, preparation time is too long, influences production efficiency.In addition, bituminous epoxy is although Coating combination, pitch can be improved
Pitch can be made to become fragile after middle addition epoxy resin, flexibility is deteriorated.
CN 104591605A disclose a kind of Warm-Mix Bitumen Mixture and preparation method thereof, in warm-mixed asphalt preparation process
It is middle and to reduce the mix and forming temperature of asphalt using a kind of special warm-mixing agent, less pernicious gas occurrence quantity.But
Be warm-mixing agent preparation process in, not only intermediate reaction speed is slower, and intermediate activity it is relatively low, cause intermediate with
The extent of reaction of aromatic naphtha, reaction depth are also not easily controlled, and obtained warm-mixing agent property is unstable, affects in pitch
Application effect.If in addition, by warm-mixing agent in bituminous epoxy, having also appeared the poor problem of anti-aging property.
During preparation flexibility good bituminous epoxy, warm mix technology would generally reduce by 60 DEG C of viscosity of pitch or prolong
Degree of stretching, to affect the high-temperature stability or low temperature anti-cracking performance of asphalt.It would therefore be highly desirable to develop one kind, both
Can solve the problem of that bituminous epoxy flexibility is poor can also solve high and low temperature performance and aging.
