In the heavy antisepsis in the field such as water-repellent paint, ship and oil field, chemical industry.Because the freezing point of pitch is high, generally to add in use
Heat can be used to 140 DEG C or so as working fluid.Use can produce problems with after pitch is heated：1. heat and be incubated
Process can consume the energy；2. harmful substance such as benzene, toluene etc. after heating in pitch can overflow, and endanger environmental and human health impacts；
3. the applied at elevated temperature of pitch can also cause potential injury to operator.
At present, it be at normal temperatures emulsion liquid that under certain condition is made for pitch, water, emulsifying agent and other auxiliary agents by people
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
Stabilization coarse granule dispersion, is that the asphalitine of solid is scattered in the dispersed phase that water, saturated hydrocarbons and emulsifying agent are formed.It is this
In storage and transport, when particularly environment temperature is high, pitch will separate, be demulsified the asphalt emulsion of dispersed from liquid phase,
Cause the asphaltene deposition of solid in holding vessel, the bottom of transport vehicle groove tank, asphalt emulsion is not only resulted in cannot be used, and to tank
The cleaning of body and reuse and cause the deuce to pay.
The current asphalt emulsion viscosity and the method for stability of improving has【1】：1. during emulsified asphalt is produced, 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 because the presence of chlorion is to emulsified asphalt
Production, storage and transporting equipment can all produce heavy corrosion.2. organic thickening agent is added, generally plus molecular weight is millions of, very
To more than several ten million high molecular polymers, the polymer of HMW needs could be molten in water under long agitation and heating
Solution, using very inconvenient, once and the polymeric membrane that is easily formed of moisture evaporation and be easily wrapped on colloid mill, cause glue
The blocking of body mill, so as to cause production disruption, and processes also highly difficult, therefore increases labour intensity, also reduces production efficiency.
In sum, there is thickener to production equipment in the method for asphalt emulsion viscosity and stability is improved at present
The technical problems such as burn into production and application is inconvenient, winding and blocking to disintegrating colloid mill head and pipeline.
Accordingly, it would be desirable 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 for blocking, improve production operation condition, improve production efficiency.
The amphiphile, amphiphilic molecule compound with Y type hydrophilic groups of current low-molecular-weight (molecular weight is 100 to 2000) is mainly used
In emulsifying agent, foaming agent, corrosion inhibiter, demulsifier, wetting agent, levelling agent and fabric finishing agent【2】, its know-why is to reduce
The surface tension and solid-liquid of solution-air, the interfacial tension of liquid-liquid.
