Abstract
The invention discloses an asphalt modifier. The asphalt modifier is formed by mixing 8-10 parts of polybutylene, 4-7 parts of a cross-linking agent, 1-3 parts of aluminum oxide and 1-2 parts of nano-micro powder. The asphalt modifier disclosed by the invention is high in permanent deformation resistance, high in low-temperature cracking resistance, high in fatigue resistance, high in water damage resistance and applicable to various occasions such as roads, bridges and roofs.
Description
Technical field
The invention belongs to properties-correcting agent field, specifically a kind of asphalt modifier.
Background technology
Asphalt modifier is the organic or inorganic material of the natural or synthetic added in pitch or asphalt, melting or the pavement performance be dispersed in improvement or raising pitch in pitch.
Modifying asphalt common at present normally has two kinds of selections, modifying asphalt and modified emulsifying asphalt.Modified emulsifying asphalt is divided into two large classes with the classes of modifiers difference used: if the asphalt modifier used is SBR class, be then called SBR modified emulsifying asphalt; Preparing this kind of modified emulsifying asphalt selects positively charged ion styrene-butadiene latex as properties-correcting agent usually, because its performance and cationic emulsified bitumen have good compatibleness, significantly can improve the softening temperature of pitch, reduces temperature, glues the weather resistance of toughness and use.If the asphalt modifier used is SBS class, be then called SBS modified emulsifying asphalt.
Because SBS polymkeric substance and pitch exist larger difference in molecular weight, density, solubility parameter and other physical quantity, chemical property etc., cause compatibility between the two and less stable.
Summary of the invention
In order to solve the above-mentioned technical problem existed in prior art, the invention provides a kind of asphalt modifier, adopting following composition to mix: polybutene 8-10 part, linking agent 4-7 part, aluminum oxide 1-3 part, nano powder 1-2 part.
Further, described linking agent is epoxy resin or DAP resin.
Further, described nano powder is carbon nanometer microtubule or silica nanometer powder.
Further, each composition is: polybutene 10 parts, linking agent 5 parts, 3 parts, aluminum oxide, nano powder 1 part.
Further, each composition is: polybutene 11 parts, linking agent 4 parts, 2 parts, aluminum oxide, nano powder 2 parts.
Further, each composition is: polybutene 8 parts, linking agent 7 parts, 1 part, aluminum oxide, nano powder 1 part.
Asphalt modifier permanent deformation resistance of the present invention is high, and anti-cold cracking ability is strong, and antifatigue is opened, anti-water damage, is applicable to road, bridge, and all kinds of occasion such as roof uses.

Controlled trial
Get 4 groups of identical matrix pitches, often organize 2000g, matrix pitch is heated to 150-160oC, wherein add the asphalt modifier of above-described embodiment one ~ tri-while stirring, use high-shear emulsion machine with 8000r/min speed shear agitation 20 minutes after preliminary mixing, modifying asphalt sample can be obtained.Test using softening temperature, penetration degree, viscosity and ductility as evaluation index respectively
The effect of properties-correcting agent of the present invention, the results are shown in Table 1.Result shows: after with the addition of properties-correcting agent provided by the invention, and the indices of pitch has and significantly improves.
Table 1 controlled trial result.
