Description
Technical field
The invention patent relates to a kind of method of viscosity and stability for improving asphalt emulsion, in particular to a kind of low molecules
Application of the Y type hydrophilic group amphiphile, amphiphilic molecule compound in terms of improving asphalt emulsion viscosity and stability is measured, asphalt applications are belonged to
Energy conservation and environmental protection.
Background technique
Pitch as petroleum refining byproduct due to good waterproof, anticorrosive property and with different kinds of roads material
The excellent caking property with construction material such as building stones, cement etc., be widely used in highway build and conserve, build in waterproof roll
In the heavy antisepsis in the fields such as water-repellent paint, ship and oil field, chemical industry.Since the freezing point of pitch is high, usually to add in use
Heat, which becomes working fluid to 140 DEG C or so, to be used.Use can generate following problems: 1. heating and heat preservation after pitch heating
Process can consume the energy；2. the harmful substance such as benzene, toluene etc. after heating in pitch can overflow, environmental and human health impacts are endangered；
3. the applied at elevated temperature of pitch also can cause potential harm to operator.
Currently, pitch, water, emulsifier and other auxiliary agents are made at normal temperature in emulsion liquid people under certain condition
To solve high energy consumption and environmental issue present in above-mentioned pitch use.This asphalt emulsion be a kind of particle diameter distribution very it is wide not
It stablizes coarse granule dispersion, is dispersed the asphalitine of solid in the dispersed phase that water, saturated hydrocarbons and emulsifier are formed.It is this
The asphalt emulsion of dispersed is in storage and transport, and when especially environment temperature is high, pitch will separate from liquid phase, be demulsified,
It causes the asphaltene deposition of solid in holding vessel, the bottom of transport vehicle groove tank, does not only result in asphalt emulsion and be not available, and to tank
It the cleaning of body and reuses and causes the deuce to pay.
The current asphalt emulsion viscosity and the method for stability of improving has [1]: 1. during producing emulsified asphalt, and nothing is added
Machine salt such as calcium chloride increases the stability of asphalt emulsion by improving emulsified asphalt viscosity, and this method improves emulsified asphalt
Viscosity is limited, and the viscosity of general asphalt emulsion is only capable of improving 10%-30%, and since the presence of chloride ion is to emulsified asphalt
Production, storage and transporting equipment can all generate heavy corrosion.2. organic thickening agent is added, usually plus molecular weight is millions of, very
To several ten million above high molecular polymers, the polymer of high molecular weight is needed could be molten in water under long agitation and heating
Solution, use is very inconvenient, once and the polymeric membrane that is easily formed of moisture evaporation and be easy to be wrapped on colloid mill, cause glue
The blocking of body mill to cause production disruption, and processing is also highly difficult, therefore increases labor intensity, also reduces production efficiency.
In conclusion there are thickeners to production equipment in the method for improving asphalt emulsion viscosity and stability at present
Burn into produces and uses inconvenience, to technical problems such as the windings and blocking of disintegrating colloid mill head and pipeline.
Therefore, it is necessary to develop one kind there is low molecular weight, soluble, corrosion-free to the equipment such as colloid mill and pipeline, nothing to twine
Around the asphalt emulsion stabilizer of blocking, improves production operation condition, improves production efficiency.
The amphiphile, amphiphilic molecule compound with Y type hydrophilic group of low molecular weight (molecular weight is 100 to 2000) is mainly used at present
In emulsifier, foaming agent, corrosion inhibiter, demulsifier, wetting agent, levelling agent and fabric finishing agent [2], technical principle is to reduce
Surface tension and solid-liquid, the interfacial tension of liquid-liquid of solution-air.
