Abstract
The invention discloses a modified asphalt additive. The modified asphalt additive is prepared from a cationic surface active agent, 3-10% ethanediol, waste rubber powder, talcum powder, an antioxidant, quartz powder and polyethylene. Low-temperature-resistant ethanediol, high-temperature-resistant antioxidant and fine quartz powder for improving strength of asphalt are added into the modified asphalt additive, and the asphalt produced by using the additive is good in high temperature and low temperature resistance, high in strength, good in various property, simple in preparing process, low in cost and suitable for large-scale industrial production.
Description
Technical field
The present invention relates to a kind of chemical industry additive, particularly a kind of modified asphalt additive.
Background technology
Bituminous pavement is generally made up of with gathering materials pitch.Pitch is widely used in pavement construction due to cheap.But the oxidation of bituminous cement during using, the use on weather condition and road surface, particularly use through heavy load, result in road surface and degenerate along with the change of time.Such as, repeatedly shrink due to temperature variation on the winter nights road surface of cold and cause road surface to form vertical crackle, be called as cold crack.Bituminous cement becomes too soft during the summer of sweltering heat, causes road surface tension set under heavy loading repeatedly, becomes " rut ".In addition, the result of continuous print mechanical stress is that road surface becomes tired, causes forming the crackle as crocodile skin, is known as repeated stress failure.The wax content of pitch is higher, causes the road surface of asphalt paving easily to soften when high temperature, and produce pile-up, permeable, phenomenon such as formation reflection crack, surface deformation etc., havoc road surface, therefore has to drop into a large amount of maintenance of surface expenses.
The method of polymer-modified asphalt and production polymer-modified asphalt is known in the art.Polymer, such as thermoplastic elastomer, combine very extensive, for improving intensity and the performance of pitch in pitch.In polymer bituminous composition, add the stability that sulphur can improve it is also known.
Summary of the invention
The object of the present invention is to provide a kind of modified asphalt additive.
For realizing above object, the present invention is achieved through the following technical solutions:
The formula of modified asphalt additive of the present invention comprises by total weight percent:
Cats product 0.5-3%
Ethylene glycol 3-10%
Waste Crumb rubber 40-60%
Talcum powder 1-3%
Antioxidant 2-5%
Silica powder 10-35%
Polyethylene 10-20%
Preferably, described cats product is ethanolamine salt.
Preferably, described antioxidant is tertiary butyl class antioxidant.
Preferably, the particle diameter of described silica powder is 200 orders.
Beneficial effect of the present invention is: add low temperature resistant ethylene glycol in modified asphalt additive of the present invention, resistant to elevated temperatures antioxidant, add the intensity that quartzy fine powder increases pitch, the pitch of Additive Production of the present invention is used to have good anti-high and low-temp performance and intensity, properties is good, and preparation technology is simple, with low cost, be applicable to large-scale industrial production.
Embodiment:
The embodiment below enumerated is specifically described the present invention.
Embodiment 1, a kind of High-and-low-temperaresistant resistant asphalt, is comprised by total weight percent by following component:
Thanomin 2%
Ethylene glycol 10%
Waste Crumb rubber 45%
Talcum powder 3%
Tricresyl phosphite (2,4-di-tert-butyl) ester 4%
Silica powder 200 order 21%
Polyethylene 15%
The above; be only the present invention's preferably embodiment; but protection scope of the present invention is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; be equal to according to technical scheme of the present invention and inventive concept thereof and replace or change, all should be encompassed within protection scope of the present invention.
