Abstract
The invention relates to a method for preparing a non-amine asphalt antistripping agent with amphoteric activity. The method is characterized by adopting the following formula and the following preparation process: a, the non-amine asphalt antistripping agent with amphoteric activity is prepared from 20 to 80 weight parts of oleic acid and 5 to 40 weight parts of amine; and b, the preparation process comprises the following steps of: adding the oleic acid and the amine into a reaction vessel according to the weight ratio; heating the mixture to 100 to 120 DEG C while stirring and inputting nitrogen; reacting for 2 to 4 hours from the beginning; continuously stirring and heating the mixture to 160 to 180 DEG C; reacting for 2 to 4 hours; cooling to obtain a semi-finished product of the non-amine asphalt antistripping agent with amphoteric activity; and adding chloroacetic acid and sodium hydroxide into the reaction vessel to react for 2 to 4 hours at the temperature of between 60 and 120 DEG C to obtain the asphalt antistripping agent, wherein the ratio of the semi-finished product to the chloroacetic acid to the sodium hydroxide is 1:1:1. The preparation method is simple, and the asphalt antistripping agent prepared by the method can greatly improve the water damage resistance of an asphalt pavement, thereby prolonging the service life of the asphalt pavement and reducing the maintenance cost.
Description
Technical field
The present invention relates to the making method of asphalt additive, especially a kind of non-amine has the making method of the asphalt anti-stripping agent of amphiprotic activity.
Background technology
The water stability of existing motorway Chang Yinwei bituminous concrete is good inadequately and cause early water infringement, road surface hole groove, phenomenon such as loose just to occur after using 2-3.Damage by water evil and rut, crack are the same, have become the main destructive factor of bituminous pavement.Bituminous pavement damage by water evil mechanism is the surfacial spalling of asphalt membrane from gather materials (building stones), and its evolution is: 1. moisture content enters into the interface that gathers materials, and exists with the form of moisture film or steam, influence pitch and gather materials between adhesivity; 2. under cyclic reverse loading, asphalt membrane begins to peel off from surface of aggregate gradually; 3. along with the further intrusion of water, the beginning of gathering materials is loose falls grain; 4. final, the damage by water harm of bituminous pavement develops into groove.Two approach of prevention of water infringement: the one, the voidage of dwindling asphalt, anti-sealing enters the inside of asphalt.But when voidage during less than limit voidage, pitch is easy to make the pitch come-up at the expanded by heating in summer, and the road surface can produce distortion such as gathering around bag, rut, and surface friction coefficient is low, and it is dangerous to drive a vehicle.The 2nd, improve pitch and the adhesivity of gathering materials.Measure and the way that adopts is at present: 1. replace breeze with a part of lime or cement, adopt ultrasonic wave to activate to gathering materials, but operation easier is big, the cost height.2. use cationic amine or metallic soap class asphalt anti-stripping agent, like this, though solved the sticking problem of pitch and acid stone, cationic asphalt anti-stripping agent and alkaline building stones produce the problem of repelling each other again, make performance of asphalt mixture be difficult to stablize.
Summary of the invention
Technical problem to be solved by this invention: be to provide making method simple, the compound of being made has antistripping effect preferably, safety and environmental protection, and be applicable to acid, two kinds of building stones of alkali, can be applicable to plain asphalt, modifying asphalt and road drainage a kind of non-amine partly and have the making method of the asphalt anti-stripping agent of amphiprotic activity.
For solving above technical problem, the technical scheme that is adopted is as follows:
A. fill a prescription: following is weight ratio
20～80 parts of oleic acid
5～40 parts of amine
The oleic acid of above-mentioned utilization is meant one or both the mixture in vegetable oil acid and the animal oleic acid.
The amine of above-mentioned utilization is meant any one or any two kinds mixture in methylamine, aniline, propylamine, butylamine, hexylamine, quadrol, hydramine, butylamine, polyethylene polyamine, octylame, oleyl amine, the amino dodecane.
B. manufacture craft flow process
By weight oleic acid and amine are dropped in the reaction vessel-→ when stirring and importing nitrogen, be warming up to 100～120 ℃-→ from beginning so far react 2～4 hours-→ continue to stir and be warming up to 160～180 ℃-→ reaction 2～4 hours-→ cooling-→ obtain the work in-process that non-amine has the asphalt anti-stripping agent of amphiprotic activity, add Monochloro Acetic Acid and sodium hydroxide (work in-process: Monochloro Acetic Acid: the sodium hydroxide mol ratio is 1: 1: 1) again, under 60～120 ℃, react and promptly got asphalt anti-stripping agent in 2～4 hours.It is as follows that resultant non-amine has the general formula of asphalt anti-stripping agent of amphiprotic activity:
R
1=C
10～C
20Or R
1=Cn Hm n=10～20, m=18～43
R
2Be carboxymethyl, propyloic or methylol
Owing to adopt above technical scheme, produced useful effect:,, be widely used in plain asphalt and modifying asphalt so be applicable to acid, two kinds of building stones of alkali because the asphalt anti-stripping agent that the present invention makes is the amphiprotic activity compound.Its making method is simple especially, with the asphalt anti-stripping agent that present method is made, can increase substantially the performance of bituminous pavement anti-water damage, has improved the anti-ageing property of bituminous, has greatly prolonged the work-ing life of drop in the road surface, reduces and reduced maintenance cost.
