Technical field
The present invention relates to material modified technical field, specifically a kind of asphalt modifier.
Background technology
Pitch has water proofing property and anticorrosive property, is widely used today as pavement material and covering material of road etc..But
The proportion of China's road asphalt is typically small, paraffin content is higher, ductility is smaller, softening point measurement value is higher, but heat endurance
Bad, brittle point is poor compared with high and low temperature cracking resistance.Generally existing poor high temperature stability, cold cracking are serious, durability is bad etc. asks
Topic.Therefore conventional pitch can not meet the requirement of high-strength, safe and stable, the resistance to performance of waiting so long of bituminous paving, together
When, import high-quality heavy oil asphalt and modified pitch are again very expensive.It must be acted upon improving the performance of pitch.
Modifying agent is dissolved or dispersed in pitch, improves or improve the pavement performance of pitch, is reduced the various diseases of bituminous paving, is prolonged
The service life on long road surface.It is exactly the method for adding high polymer that asphalt modification is most representative in Current Highway engineering, is used
Such as directly matrix pitch and modifying agent is blended in stirring, high speed shear method to certain technological means, due to high polymer in itself
The particularity of structure, forms physical entanglement point in pitch, so that the movement of pitch is restricted, sensitiveness of the reduction pitch to temperature
With the mechanical property of pitch.
The content of the invention
The present invention is directed to the weak point of existing asphalt modifier there is provided that can significantly improve asphalt performance, with good
Stability, the asphalt modifier that softening point is high, dispersive property is good.

15 parts of 12 parts of sodium alkyl sulfate and graphene.
Further, the preparation method of the asphalt modifier, it is characterised in that：It is that each raw material is added into mixer, often
Temperature lower stirring 10-20 minutes, produces asphalt modifier.
Further, the doping of the asphalt modifier is the 1-3% of pitch weight.
Compared with prior art, beneficial effects of the present invention are：
1st, asphalt modifier good dispersion of the invention, softening point height, good stability, safety and environmental protection, good flowing properties, weatherability
Good and pitch caking property can improve by force the mechanical property of pitch, can significantly improve the toughness of pitch, and the road of enhancing bituminous paving is used
Property.
2nd, the present invention added in modifying agent with high temperature resistant, chemical property is stable, greasy property is good, specific surface area is big,
The graphene for the characteristic such as mechanical property is strong, electrical and thermal conductivity performance is strong, can significantly improve the mobility and stability of pitch.
3rd, modifying agent of the invention doping in bitumen construction is low, preparation technology it is simple that, it is with low cost, easily realize
Industrialized production.
