Abstract
The invention relates to an additive of an asphalt material for road construction, in particular to a non-amine liquid asphalt anti-stripping agent applied to a high-speed road construction asphalt material and a preparation method thereof. The raw material components of the non-amine liquid asphalt anti-stripping agent include phosphate ester, ethanol, fatty acid and sodium lignin sulfonate in the mass ratio of (5-5.5):(1-1.5):(2-3):(1-1.5). In the invention, the phosphate ester is added into the components of the anti-stripping agent and serves as a flame retardant, so that the aging resistance of the anti-stripping agent is greatly improved. Moreover, the ethanol is added into the raw material components of the anti-stripping agent, so that the problem of durability of a product is well solved.
Description
Technical field
The present invention relates to be used for the additive of the bituminous material of road construction, specifically is a kind of non-amine eu-bitumen antistripping agent that is used for motorway construction bituminous material and preparation method thereof.
Background technology
According to design specifications, under the situation of using acid stone,, must add asphalt anti-stripping agent when building motorway for the adhesivity that makes pitch and building stones reaches 5 grades.Only in this way could reduce and resist the infringement of water, prolong the work-ing life of motorway motorway.For the high grouan of tart dioxide-containing silica that motorway uses, building stones such as Irish touchstone and bituminous adhesivity have obvious effects, can bring up to 4-5 level adhesivity from the 1-2 level.Asphalt anti-stripping agent great majority domestic production at present and the liquid form that motorway uses are amines.The long-term ageing-resistant performance of the asphalt anti-stripping agent of amine is bad, according to the standard test, amine asphalt anti-stripping agent is carried out 163 ℃; Behind 5 hours aging, adhesivity can reach 5 grades for qualified, at 163 ℃ after aging 10 hours; Adhesivity does not reach 5 grades, and the center is divided into 4 grades (defective), continues 163 ℃ and wears out 20 hours; After 48 hours, asphalt anti-stripping agent all lost efficacy, and pitch is with the adhesivity of building stones and do not add when pitch is anti-shells agent the same.
The bituminous concrete that uses in the road construction is to be mixed and stirred at 180 ℃-190 ℃ by pitch, building stones; Be transported to then that highway pavement lays; And the aging point of bituminous is from greater than 170 ℃ of beginnings, surpass 170 ℃ after pitch along with time lengthening, pitch begins to wear out; Performance begins to descend, degree of aging here and degradation with 170 ℃ after temperature and time be directly proportional.163 ℃ of traditional amine asphalt anti-stripping agents, just aging after 5 hours, more be difficult to adapt to 180 ℃-190 ℃ the temperature condition that mixes and stirs.
Summary of the invention
The present invention wants the technical solution problem to be, provides a kind of and in express highway pavement construction, can improve the ageing-resistant ability of asphalt under hot conditions, improves adhering non-amine eu-bitumen antistripping agent and preparation method thereof.
The raw material composition of non-amine eu-bitumen antistripping agent of the present invention consists of phosphoric acid fat, ethanol, lipid acid, sodium lignosulfonate, and the mass ratio of said each composition is (5～5.5): (1～1.5): (2～3): (1～1.5).
The preparation method of above-mentioned non-amine eu-bitumen antistripping agent is; After the phosphoric acid fat of required ratio is heated to 50 ℃ of-55 ℃ of dissolvings, add ethanol, lipid acid, the sodium lignosulfonate of required ratio, constant temperature is at 55 ℃-60 ℃; Reacted 0.8～1.2 hour, and obtained the antistripping agent finished product.
Added phosphoric acid fat in the antistripping agent composition of the present invention; This is a kind of fire retardant, and it has improved the ageing-resistant ability of antistripping agent greatly, actual test; Use the bituminous concrete of antistripping agent of the present invention; At 163 ℃ after aging 48 hours, the adhesivity of pitch and building stones still can reach 5 grades, this be amine asphalt anti-stripping agent can't be obtained.In addition, because phosphoric acid fat is met air oxidizing reaction can be taken place under normal temps, its performance can progressively descend, and about 3-5 of time month, thus can influence durability of products.Of the present inventionly solved the durability of products problem well through in antistripping agent raw material composition, adding ethanol, through actual tests, outdoor storage was used for bituminous concrete after 3 years in the open air, and the adhesivity of pitch and building stones still reaches 5 grades.
Embodiment
The preparation embodiment of the non-amine eu-bitumen of the present invention antistripping agent is following: (50 ℃-55 ℃ of temperature) adds 1.2 parts of ethanol after 5 parts of heating for dissolving of phosphoric acid fat; 2.8 parts in lipid acid; 1 part of sodium lignosulfonate, constant temperature let it react 1 hour at 55 ℃-60 ℃; Obtain the antistripping agent finished product, product P H value 3-5.
The key technical indexes of the foregoing description product is following:
Composition: non-amine organic cpds
Outward appearance: chocolate liquid
Invalid temperature:＞300 ℃
Solvability: good consistency is arranged with hot-melt asphalt
Security: nontoxic, free from extraneous odour, pollution-free, nonflammable
The method of use of the foregoing description product is following:
Usage quantity: 0.2～0.4% (accounting for the ratio of heated bitumen, down together).Consumption 0.3～0.4% under the proportioning of heavy-duty road petroleum pitch and Irish touchstone isogonic acidity aggregate.If modifying asphalt, consumption 0.2～0.3%.Can directly add in the heated bitumen, be thorough mixing with bitumenpump circulation secondary, do not need special-purpose whisking appliance.
Adhesivity before and after the foregoing description product and amine asphalt anti-stripping agent are aging contrasts as follows:
Claims (2)
