Abstract
The invention discloses a kind of preparation methods of epoxy resin modified emulsified asphalt, including routinely asphalt emulsification method emulsifies after mixing epoxy resin with the matrix pitch of heating；It has the following characteristics that first, only need to can be obtained epoxy-modified emulsified asphalt by once emulsifying process, not need individually to carry out Water-borne modification processing to epoxy resin, reduce manufacturing procedure；Secondly, when epoxy resin is heated to 130 DEG C or so, with extremely low viscosity, it is evenly dispersed in pitch to be conducive to epoxy resin, therefore the addition of epoxy resin can reduce heated bitumen viscosity, implement convenient for emulsification, and latex particle size can be effectively reduced, is conducive to the stable storing of lotion, at film uniformity and mixes and stirs process and uniformly wrapped to what is gathered materials；Third, be the mixture of pitch and epoxy in single emulsion particle, emulsion particle demulsification process be it is simultaneous, epoxy resin is uniformly distributed in pitch kind after demulsification is formed a film, and is promoted modified effect, be can get superior performance.
Description
Technical field
The present invention relates to the method for modifying of emulsified asphalt, in particular to a kind of preparation side of epoxy resin modified emulsified asphalt
Method.
Background technique
Emulsified asphalt can room temperature construction, mix and stir the more environmental protection, convenient of class asphalt material relative to heat, be widely used in bituminous pavement
Substructure and sealing, adhesion coating, top dressing and other functional layers, are also used for all kinds of protection works such as waterproof and anti-corrosion.But cream
Change pitch bonding capacity be markedly less than hot asphalt, be restricted its application surface, such as: with emulsified asphalt with gather materials by cold
The mixture that construction obtains is mixed and stirred, pavement performance index is difficult to reach top course mixture performance requirement.Using cohesive force compared with
Strong epoxy resin, is modified emulsified asphalt, its performance can be improved, widen application range.Epoxy-modified emulsification drip at present
Green method is equal are as follows: added in emulsified asphalt aqueous epoxy resins (including water-soluble epoxy resin, epoxy resin latex) and
Auxiliary agent, it is mixed and modified, and achieve certain effect.Such as: CN102010607 emulsifies double A with alkylphenol polyethylene oxide
Type epoxy resin is synthesized by mixing, and it is mixed with the one or more of modified fatty amine, phenolic aldehyde amine, aromatic amine etc. to form asphalt mixtures modified by epoxy resin
Epoxy curing agent, rouge water-in-oil emulsion is made in the aqueous solution for closing amine and alkylphenol polyethylene oxide；The epoxy resin water made
Emulsion is mixed into emulsified asphalt, and thermosetting epoxy resin modified emulsified asphalts are then made after being sufficiently mixed.CN106700577
The raw material of waterborne epoxy modified emulsified asphalt of the invention includes emulsified asphalt, aqueous epoxy resins, styrene-butadiene latex, aqueous acrylamide
Acid resin and dispersing agent.In CN102322009, epoxy resin is mixed with hydrophilic active diluent ethylene glycol diglycidylether
It closes after diluting, then is reacted with the unit polyetheramine of hydrophilic polyethanol base (PEG), the hydrophilic epoxy tree of emulsifier-free is made
Rouge, the hydrophilic matrix tablets aqueous solution without emulsification made byIt is mixed into emulsified asphalt, after being sufficiently mixed then
Thermosetting epoxy resin modified emulsified asphalts are made.Aqueous epoxy resin emulsion, solidification is added in CN1903941 in emulsified asphalt
Agent.100 parts of CN102746822 modified emulsifying asphalt, 5-8 parts of water, 4-9 parts of aqueous epoxy resins, aqueous epoxy curing agent.More than
The deficiencies in the prior art are: first, the emulsification of pitch and the emulsification (or hydrophilic modifying) of epoxy resin carry out respectively, respectively into
Row is processed twice, and process is more；Second, for the epoxy emulsion and asphalt emulsion of simple physical mixing, two kinds of emulsification systems
De-emulsification speed is different, i.e., first demulsification person is first precipitated, and rear demulsification person cannot be held into wherein, as a consequence it is hardly possible to while being demulsified and to form blending
Uniform two-phase system, therefore better modified effect cannot be obtained.
Summary of the invention
It, can one in view of this, the purpose of the present invention is to provide a kind of preparation method of epoxy resin modified emulsified asphalt
Secondary property emulsifies to obtain epoxy-modified emulsified asphalt, and epoxy resin can be uniformly distributed in pitch kind, can effectively reduce latex
Grain partial size, be conducive to lotion stable storing, at film uniformity and mix and stir process to gather materials uniformly wrap.
The preparation method of epoxy resin modified emulsified asphalt of the invention, comprising the following steps: by epoxy resin and heating
Matrix pitch mixing after routinely asphalt emulsification method emulsify；
Further, matrix pitch is heated in flow regime；
Further, matrix pitch is heated to viscosity≤0.4Pa.s；
Further, adjusting temperature makes uniformly mixed mixture viscosity≤0.3Pa.s；
Further, the mass ratio of the matrix pitch and epoxy resin is 100:5~100:50；
Beneficial effects of the present invention: the preparation method of epoxy resin modified emulsified asphalt of the invention has the following characteristics that
First, only epoxy-modified emulsified asphalt need to be can be obtained by primary emulsification process, do not need individually to epoxy resin into
The processing of row Water-borne modification, reduces manufacturing procedure；Second, having when epoxy resin is heated to 130 DEG C or so (pitch condensing temperature)
Extremely low viscosity, is conducive to that epoxy resin is evenly dispersed in pitch, therefore the addition of epoxy resin can be by heated bitumen viscosity
Reduce, implement convenient for emulsification, and latex particle size can be effectively reduced, be conducive to the stable storing of lotion, at film uniformity and
Process is mixed and stirred uniformly to wrap to what is gathered materials；Third, being the mixture of pitch and epoxy in single emulsion particle, due to only a kind of
Emulsifier protective layer, emulsion particle demulsification process be it is simultaneous, enable demulsification form a film after epoxy resin it is equal in pitch kind
Even distribution, further promotes modified effect, can get superior performance.
