Abstract
An asphalt emulsion is prepared from asphalt, water, emulsifier, stabilizer and polymer. The preparing process includes heating various asphalts with mild fire at 120-150 deg.C for dewatering, heating water to be water of 45-65 deg.C, adding emulsifier, stabilizer and polymer in heated water for making emulsified aqueous solution in emugator, adding heated asphalt at required temp in emulgator and obtaining stable emulsion through high speed shearing and dispersing.
Description
Technical field
The present invention relates to a kind of effective constituent of using organic polymer material as mortar, concrete, rostone or other analogous material, be meant that especially railway or urban light rail ballastless track with asphalt emulsion and its preparation method in the packing material, belong to railroad track or urban light rail vibration and noise reducing material.
Background technology
Rail such as railway or urban light rail Motor vehicles all are equipped with track below rail, now the track of rail Motor vehicles divides two kinds of ballasted track and ballastless tracks.The workload that ballasted track is laid the back operation maintenance is very big, structural instability, and also train speed is subjected to certain restriction, adopts ballastless track to address the above problem preferably.Be particularly suitable on bridge, tunnel and urban light rail, using.Plate-type slag-free orbit is one of basic structure of existing railway or urban light rail ballastless track, this ballastless track is to lay concrete bed on roadbed, on base, set up the track plate, reserve space 5CM between the two, be used for pouring into packing material cement asphalt mortar (hereinafter referred to as the CA mortar).The CA mortar is the key components that railway or urban light rail ballastless track structural elasticity are adjusted layer, excellent properties such as have that aggregate such as sand does not separate, vibration resistance excellence, sclerosis back volume slightly expand.At present, the CA mortar also is in the pilot development stage at home, does not still have the product of performance excellence.Chinese patent ZL02139237.Though 4 disclose a kind of slag-free orbit CA mortar, but through carried out the examination shop of plate-type slag-free orbit at Qinhuangdao Shenyang Special Passenger Line dog river grand bridge and two rivers grand bridge in China, its practical application effect is still undesirable, existing C A mortar mainly exists aggregates such as degree of mobilization is bad, operable time weak point, sand easily to separate, deficiencies such as volume shrinks to some extent after hardening simultaneously, why by researching and analysing above-mentioned phenomenon can appear, a very important reason is exactly that the performance of CA mortar medium pitch emulsion does not still reach desirable requirement, so still be necessary this is improved.
Summary of the invention
The objective of the invention is deficiency at existing CA mortar medium pitch emulsion provides asphalt emulsion that a kind of new cement asphalt mortar uses and preparation method thereof, to satisfy railway or the cement asphalt mortar requirement of urban light rail ballastless track.
The objective of the invention is to be achieved through the following technical solutions: asphalt emulsion is carried out proportioning (mass parts, down together) by following prescription:
Pitch, 50-65 part; Water, 30.0-45.0 part; Emulsifying agent, 1.20--3.00 part; Stablizer, 1.00-3.00 part; Polymkeric substance 0.010-0.050 part.
The said pitch of the present invention can be straight-run pitch, oxidized bitumen, bituminous composition, petroleum pitch, coal-tar pitch.
The said emulsifying agent of the present invention can be that a kind of in conventional non-ionic type, cationic, the anionic asphalt emulsifier or two kinds, three kinds are composited.
The said stablizer of the present invention can be inorganic salt, as vitriol, nitrate, hydrochloride etc.; Can be mineral acid or organic acid, as lipid acid, acetic acid, hydrochloric acid, tartrate etc.; Can be polyvinyl alcohol, Mierocrystalline cellulose; Also can be above-mentioned two kinds or three kinds and mix use.Function of stabilizer mainly is to improve the package stability of asphalt emulsion and increase emulsifying effectiveness.
Non-ionic polymers in the said asphalt emulsion of the present invention can be that a kind of or two kinds of mixing in polypropylene acid, Polyurethane, the Vinyl Acetate Copolymer etc. are used.It mainly acts on is the content that increases resin in the asphalt emulsion, and increased viscosity forms so-called emulsion.Polymkeric substance plays a part very big outside preventing the layering of CA mortar material, reducing aspect the amount of water.
Preparation technology's flow process of asphalt emulsion of the present invention is as follows: earlier various pitches are arrived 120--150 ℃ by the fiery dehydrothermal of proportioning deal temperature, water is heated to 45--65 ℃ again, emulsifying agent, stablizer and polymkeric substance etc. are added in the hot water, stir, make aqueous emulsion, aqueous emulsion is added in the mulser, add the heated bitumen meet temperature requirement then, under the high speed shear of mulser, dissemination, form uniform and stable emulsion.
The present invention is by adding a small amount of non-ionic polymers in asphalt emulsion, and constitute a kind of composite type pitch emulsion, so when material mixing such as asphalt emulsion of the present invention and cement and sand form the CA mortar, can make aggregate such as sand not produce separation, have elasticity, resistance to vibration excellence and sclerosis back volume slightly expand, and can satisfy the requirement of the packing material of railway or city ballastless track fully.
