Description
Technical field
The invention belongs to chemical material field, and in particular to a kind of long-acting asphalt anti-ageing agent and preparation method thereof.
Background technology
In recent years, with the fast development of China's transport service, the volume of traffic increasingly increases, and highway construction is also developed with the speed maked rapid progress.By 2010, national highway reached 398.40 ten thousand kilometers, and high-grade highway has reached 7.40 ten thousand kilometers.Bituminous paving has excellent performance and road-ability, is the main cause of the fast development of transport development cause, therefore majority is to use bituminous paving in the at present high-grade highway built by China, and the application in common grade highway also account for sizable proportion.Bituminous paving subjects the multiple action of huge traffic load and factor of natural environment, thus proposes higher and higher requirement to the quality of its pavement material.
In viability due to aging and performance that affect road surface causes its durability not enough, so that the service life of bituminous paving shortens, this is always problem of countries in the world concern to bituminous paving.Ageing of asphalt has two kinds of short ageing and long-term ageing.Short ageing refer to Colophonium storing and transporting, mix and stir with paving process so as to expose to the open air in natural environment, the component in Colophonium occur volatilization, oxidation, decompose, the physicochemical change such as polymerization so that the performance of asphalt pavement material changes.Long-term ageing refers to bituminous paving during long-term use, it can be exposed in natural environment for a long time, under conditions of the natural climate of light, oxygen and rainwater etc., there is series of physical and chemical change in asphalt material, so as to cause the change of property, the slow long-term process of deterioration one of bitumen properties.
A kind of Chinese patent 201110328907.7, it is proposed that road petroleum asphalt anti-ageing agent and preparation method thereof.The asphalt anti-ageing agent proposed by the method by 10%～60% additive B and 90%～40% basis soft component C constitute.Wherein basic soft component C is bi tumenf orr oad or the mixture rich in aromatic component or both, and additive B includes the component of following weight proportion：Radical scavenger 30%～55%；Peroxide decomposer 15%～30%；Light stabilizer 10%～20%；Complexing of metal ion agent 10%～40%.Preparation method is that basic soft component C is heated to 70～150 DEG C, and under agitation, each component being separately added in additive B obtains road petroleum asphalt anti-ageing agent after stirring.The aging resistance have usage amount few and it is good with bitumen compatibility the characteristics of, can effectively extend the service life of bituminous paving.But it is substantial amounts of in the asphalt anti-ageing agent synthesis material proposed by the method to have used the component rich in aromatic hydrocarbon, shown according to multinomial risk evaluation result, the chemical productss of aromatics have extremely strong destructiveness, or even cause cancer to the reproductive system of human body, respiratory system and immune system.Therefore the age resister is not appropriate for large-scale use.
A kind of Chinese patent 201410617872.2, it is proposed that asphalt anti-ageing agent and its preparation method and application.The asphalt anti-ageing agent includes aromatic naphtha 35-55wt%, alpha-naphthylamine 30-50wt%, emulsifying agent 5-10wt% and water 5-10wt%, adds alpha-naphthylamine in aromatic naphtha, after fully dissolving, adds emulsifying agent and water into which, so as to age resister is obtained.The age resister proposed by the invention is difficult to the production and processing of the bad Colophonium of qualified and thermmal storage for ductility after thin film oven and needle penetration, while, it is also possible to extend the service life of road.But, the aromatic naphtha that the invention is used also belongs to arene Organic substance, and the toxic action to human body is stronger, does not meet requirement of the today's society to environmental protection.And the age resister composition is excessively simple, the effect for delaying ageing of asphalt speed is simply simply realized.And its physical stability is poor, particularly during summer, under road surface is often in the condition of high temperature, once experience rain drop erosion will depart from Colophonium in a large number, protective effect is lost.
The content of the invention
For the deficiencies in the prior art, the present invention proposes a kind of long-acting asphalt anti-ageing agent and preparation method thereof.On the premise of ageing-resistant long-time stability are ensured, the raw material of asepsis environment-protecting is used, which prepares and does not have any hazardness to human body, environment using process.With important economic worth and the value of environmental protection.
Long-acting asphalt anti-ageing agent provided by the present invention is made up of the raw material of following weight portion：
White carbon black 20-30 parts；
NPE 5-10 parts；
Sodium xanthogenate 4-8 parts；
Stabilizer 10-15 parts；
Water 10-15 parts.
The particle size carbon black is 20-45nm；The stabilizer preparation method is：The antioxidant DLTP for waiting parts by weight is uniformly mixed with light stabilizer UV-770.
The present invention provide long-acting asphalt anti-ageing agent preparation method be：
Stabilizer, sodium xanthogenate are added to the water, 120-150 DEG C is mixed and heated to and with 500-800 rev/min of rotating speed stirring 30-50 minutes.Then mixed solution is cooled to into less than 30 DEG C, NPE and white carbon black is stirred and be slowly added to 1000-1200 rev/min of rotating speed, continued stirring 1-2 hours after all adding, that is, obtain required asphalt anti-ageing agent.
The invention has the beneficial effects as follows：Long-acting asphalt anti-ageing agent provided by the present invention has the advantage that：（1）Raw material is environment friendly and pollution-free, is not used any to environment or the poisonous and hazardous material of human body, and the Organic substance in raw material does not have volatility, and any waste is not produced in production process；（2）Self stability is good, and the stabilizer added in raw material effectively improves the stability of age resister itself, and the more common age resister of its ageing resistance can extend more than 5 years；（3）Ageing resistance is strong, and its aging resistance principle combines physical method and chemical method, white carbon black composition in raw material can effectively weaken physical damage of the ultraviolet in sunlight to Colophonium, and remaining composition then chemically improves the ageing resistance of pavement asphalt in structure.
