Description
Technical field
The present invention relates to asphalt emulsifier technical field, be mainly concerned with one and split slowly fast solidifying type cation asphalt emulgent and preparation method thereof.
Background technology
China's bituminous pavement major part is all in excess load or extended active duty state at present, and road conditions are poor, are difficult to adapt to the needs of current Ferry Status; The Asphalt Pavement of Highway of having built since twentieth century the 80s and 90s in addition also needs to carry out frequent maintenance.In pitch or asphalt, add natural or synthetic organic or inorganic material, natural or synthetic organic or inorganic material melting or be dispersed in and react with pitch in pitch or wrap on asphaltaggregate surface, can improve or improve the Pavement Performance of pitch, it is emulsified bitumen, emulsified bitumen refer to by the pitch of melting and emulsifier aqueous solution quantitative pass through a kind of suspension liquid of obtaining after high-speed shearing equipment, wherein pitch particle is dispersion, and water is disperse phase.The properties of emulsified bitumen is all determined by emulsifying agent, such as the fineness of pitch particle, speed of the stability in storage of emulsified bitumen and emulsified bitumen breakdown of emulsion process etc.The pavement diseases such as the wearing and tearing of original bituminous pavement, aging, crack, smooth, loose, hollow can be repaired rapidly and improve to Emulsified Asphalt Thin Paste Seal Technique, significantly improves waterproof, antiskid, smooth, the wear resisting property of bituminous pavement.Emulsified Asphalt Thin Paste Seal Technique is subject to the attention of highway, municipal sector with its good performance and significant economic results in society, and is widely applied in Road maintenance, has obtained more significant effect.
The difficult problem that at present China's Emulsified Asphalt Thin Paste Seal Technique is relatively given prominence to is to lack splitting slowly of being applicable to that Slurry Seal Technology requires soon coagulate and be open to traffic soon type asphalt emulsifier, and its main manifestations is that kind is single, quality is unstable, breakdown of emulsion curring time is grown etc.In recent years, socio-economic development is rapid, and close traffic is more difficult, and on especially busy arterial highway and urban road, contradiction is particularly outstanding.
In view of foregoing description, urgently there is a kind of appearance of splitting slowly fast solidifying cation asphalt emulgent for slurry seal of high-quality, in order to develop China's Emulsified Asphalt Thin Paste Seal Technique.
