Abstract
The invention relates to an attapulgite asphalt modifier belonging to the technical field of asphalt material processing. The attapulgite asphalt modifier is composed of the following components in percentage by weight: 70-90% of attapulgite clay and 10-30% of methyl silicone oil. The attapulgite asphalt modifier has the following advantages: the used attapulgite clay itself has high viscosity, and can increase the viscosity of asphalt and improve the high-temperature and low-temperature performance of asphalt; the used methyl silicone oil can reinforce the action of the attapulgite clay and the asphalt, increase the dispersion stability and toughness of the attapulgite clay in the asphalt and overcome the asphalt cracking problem; and the technique is simple and beneficial to industrial production.
Description
Technical field
The present invention relates to a kind of attapulgite asphalt modifier, belong to the bituminous material processing technique field.
Background technology
Pitch is a kind of thermoplastic material, and bituminous pavement is aging in order to solve, the rimose problem, need carry out modification to pitch.At present mainly be to make through the mode modification that in pitch, adds polymkeric substance; Material commonly used mainly comprises butadiene-styrene thermoplastic elastomer, styrene-butadiene rubber(SBR), ethylene-vinyl acetate copolymer and Vilaterm etc., and the adding of these polymkeric substance can improve the bituminous temperature sensibility greatly.Through adding inorganic modified dose; Also can obviously improve the bituminous high and low temperature resistance; Patent ZL200610167622.9 discloses a kind of method of improving performance of diatomite modified asphalt material; It mainly is through utilizing surface-modifying agent that zeyssatite is carried out surface-treated, improve diatomite particle and bituminous consistency, and then significantly improves the performance such as high-low temperature resistant, intensity, toughness of diatomite modified asphalt ground surface material.
Attapulgite clay is a kind of natural, unique silicate minerals; Have fibrous or the rhabdolith structure, have the favorable mechanical mechanical property, be viscosity and plasticity-when moist; Dry shrinkage is little; And do not produce be full of cracks, China's attapulgite clay aboundresources has tangible price advantage.
Summary of the invention
The objective of the invention is to have aging, rimose problem and a kind of attapulgite asphalt modifier is provided to bituminous pavement.
The technical scheme that realizes the object of the invention is: a kind of attapulgite asphalt modifier, to form by attapulgite clay and methyl-silicone oil, and said attapulgite clay content is that 70～90% (weight), said methyl-silicone oil content are 10～30% (weight).
Attapulgite clay of the present invention and methyl-silicone oil are the commercially available prod, and wherein said attapulgite clay is for adopting the attapulgite clay raw ore of Xuyi, and the viscosity of described methyl-silicone oil is 10000～30000 mm
2/ S.
The working method of attapulgite asphalt modifier of the present invention is: with above-mentioned materials of weight proportions, under 60～80 ℃ of conditions, stir even mixing, naturally cooling promptly gets asphalt modifier of the present invention.
Obvious advantage and effect that the present invention has:
1. the attapulgite clay selected for use of the present invention itself has high viscosity, can improve bituminous viscosity, improves bituminous high and low temperature performance.
2. the methyl-silicone oil selected for use of the present invention can be strengthened attapulgite clay and bituminous effect, improves dispersion stabilization and the toughness of attapulgite clay in pitch, improves bituminous cracking problem.
3. this technology is simple, helps suitability for industrialized production.
Embodiment
Below further specify beneficial effect of the present invention through embodiment.
Embodiment 1
With attapulgite clay 70g and methyl-silicone oil 30g, under 60～80 ℃ of conditions, stir even mixing, naturally cooling promptly gets asphalt modifier of the present invention.
Embodiment 2
With attapulgite clay 90g and methyl-silicone oil 10g, under 60～80 ℃ of conditions, stir even mixing, naturally cooling promptly gets asphalt modifier of the present invention.
Embodiment 3
