Description
Technical field
The present invention relates to high-speed railway plate-type ballastless track building material field, be specifically related to a kind of high-speed railway emulsified bitumen emulsifying agent and preparation method thereof.
Background technology
Slab track is a kind of non-fragment orbit structure of suitable Development of High Speed Railway, and it is more stable than tiny fragments of stone, coal, etc. track is arranged, and operation maintenance amount and maintenance cost are well below tiny fragments of stone, coal, etc. track is arranged.Cement emulsified asphalt mortar is the key components of slab track, it is mixed at normal temperatures by multiple starting material such as emulsified bitumen, cement, fine aggregate, admixture, polymer emulsion, water, aluminium powder, various admixtures and makes, it adjusts filling bed as the elasticity between slab track concrete bed and track plate, is a kind of concrete rigidity and elastic semi-rigid body of pitch of having concurrently.The main effect of cement emulsified asphalt mortar filling bed has: the one, can fill up the gap of track plate and concrete base bed board fully, and play a supportive role; The 2nd, can partly provide track elasticity, play the buffer shock-absorbing effect; The 3rd, can be deformed in a certain limit substructure and study for a second time courses one has flunked.Therefore, cement emulsified asphalt mortar performance quality directly has influence on ride comfort, comfortableness, the weather resistance of plate-type ballastless track structure.
Emulsified bitumen is the key components of cement emulsified asphalt mortar, and it also need possess many special performances except will satisfying common emulsified asphalt use standard.As higher evaporation residue content, good cement adaptability, thermal adaptability etc.In order to adapt to the fast development of high-speed railway, the consumption of emulsified bitumen also increases day by day.Because emulsified bitumen is about 100 ℃ when just having prepared, in order to enhance productivity, emulsified bitumen must be able to be lowered the temperature rapidly, and has good preservation stability, so that long-distance transport and use.The emulsified bitumen thermostability that present used emulsifying agent is prepared is bad, all requires slowly cooling, needs strictness control cooling rate, otherwise very easily causes the emulsified bitumen breakdown of emulsion.Therefore, a kind of novel high ferro with better thermostability becomes the focus of present research with emulsifying agent.
Summary of the invention
The invention discloses a kind of high ferro emulsified bitumen emulsifying agent and preparation method thereof for overcoming above-mentioned the deficiencies in the prior art.These emulsifier production raw material sources are extensive, cheap, and prescription rationally, the preparation method is convenient, and the most outstanding characteristics are to have good thermostability, can be widely used in the high ferro emulsified bitumen, improve the performance of emulsified bitumen, improved production efficiency and economic benefit.

(4) the said products is cooled to room temperature, adds auxiliary agent 3, be stirred to material and mix fully, promptly get the emulsifying agent finished product.
The present invention develops heat-staple emulsifying agent and is intended to solve high ferro with the emulsified bitumen existing relatively poor problem of thermostability, and composite by this thermally-stabilised emulsifying agent realized thermostability height, adaptable high ferro Preparation of Emulsification Asphalt.Its advantage is specific as follows:
(1) thermostability height
The alkyl amine emulsifying agent belongs to cationic surfactant, and it has a lower limit temperature is Kraft point, and the alkyl amine emulsifying agent can be separated out with crystalline hydrate solid form when temperature is lower than this, causes the emulsified bitumen breakdown of emulsion; And the polyxyethylated alkylphenol emulsifying agent belongs to nonionic emulsifier, and they have a ceiling temperature is cloud point, and when temperature was higher than this, the hydrogen bond action that such emulsifying agent generates because of the polar group in the molecule and water weakens separated out, and causes the emulsified bitumen breakdown of emulsion.When therefore using any emulsifying agent separately, variation of temperature all can cause breakdown of emulsion easily.But after both are mixed with certain proportion, compare with single, Kraft point obviously descends, and cloud point also significantly rises.This is because both have produced the intensive synergistic effect after mixing, and can not separate out in wider temperature range, does not take place to change mutually, thereby has guaranteed the stability of emulsified bitumen in wide temperature range, is adapted to produce fast and extensive the storage.
(2) applied widely
High ferro emulsified bitumen provided by the invention except the wide characteristics of thermal adaptation scope, also has the advantage of carrying out adjustability at varying environment with emulsifying agent.Promptly for particular surroundings, utmost point low temperature area as China southern high-temperature area or northeast, northwest, can be by changing the ratio of alkyl amine emulsifying agent and polyxyethylated alkylphenol class emulsifying agent, or the content that changes interpolation auxiliary agent 1 and auxiliary agent 2 is adjusted the Applicable temperature of emulsified bitumen, thereby obtain the required emulsified bitumen of special construction environment, solve the high ferro that causes because of the emulsified bitumen poor stability under high temperature and the cold condition and lay the difficult problem that to carry out, expanded the scope of application of emulsified bitumen greatly, prolong the high ferro construction time limit, had higher economic results in society.
(3) good with other starting material intermiscibilities
Emulsified bitumen by emulsifying agent preparation provided by the invention has no adverse effect to other performances of CA mortar.Production technique is simple, and is pollution-free, is easy to industrialization.
