Description

Color emulsified asphalt and preparation method thereof
Technical field
The invention belongs to road engineering emulsified bitumen and processing technology thereof, specifically introduce a kind of composite modified color emulsified asphalt prescription that is used for colored little table place and preparation method thereof.
Background technology
The color asphalt road surface has obtained using widely on highway, cycle track, sidewalk, bus special line, walking area, square and family expenses track.
At present, had many patents and document to disclose chromatic bituminous cement separately, the suitability for industrialized production that has is as US4629754, US5340869, GB1226234, EP-A0179510, the disclosed technology of EP-A0330281.Chinese patent ZL03802619.X discloses a kind of colourable binder compositions that is used for synthetic asphalts, described composition contain resin, lubricating oil and/or lubricating oil extract and represent by following general formula and be 0.05 to the amide additive that is lower than 3wt%: R ↑ [1]-CO-NH-(CH ↓ [2]) ↓ [x]-NH-CO-R ↑ [2] based on whole composition levels scope, wherein, R ↑ [1] and R ↑ [2] represent to have the alkyl of 10~60 carbon atoms independently of one another, and x is 1~4 integer; Chinese patent ZL93107531 discloses a kind of colored road surface agglutinate, its composition comprises that mainly petroleum resin, SBS and lube oil finishing extract oil out, more than the principal feature of these patents be to be to adopt resin, lubricating oil and/or lube oil finishing to extract the synthetic asphalts that oil and a spot of mixed with polymers form colourable binder compositions out.
The shortcoming of these patents is: chromatic bituminous cement need heat in iron ware in use, also to be driven on the mixing apparatus after the heating by iron pipeline, and in iron ware, measure before mixing and stirring cylinder entering, all these processes all are the pollutions for fear of dark asphalt, and above device all can't use the device of dark asphalt, need carry out special transformation to mixing apparatus, in transportation, also need transport liquid bituminous special-purpose vehicle, perhaps need extra dumping equipment and color asphalt bunkerage, also need to install special-purpose dyeed agglutinate transport pipe and special-purpose dyeed agglutinate weigher when on mixing apparatus, using, the high-temperature behavior of these stainable bituminous cements is compared with dark asphalt with adhesion property in addition, and big gap is arranged on performance; Because the compound of this bitumen production is generally wanted making 3 cm thicks at least, cause every square of colored road surface cost very high in addition.
If adopt emulsified bitumen to construct, its workability is better, can construct at normal temperatures, and making thickness is less than 1 centimetre, and every square of colored road surface cost is very low.There are multiple technologies to relate to for this reason and adopt color emulsified asphalt to carry out the making of colored road surface.The application at colorful slurry sealing layer of a kind of colorful asphalt emulsion and preparation method thereof and colorful asphalt emulsion is disclosed as Chinese patent 200710074922.Chromatic bituminous cement, emulsifying agent, additive, water are mixed stirring in proportion, make colorful asphalt emulsion.Colorful asphalt emulsion and mineral aggregate, tinting material, water are mixed and stirred, make the colorful slurry compound, the construction that paves then makes colorful slurry sealing layer; Chinese patent 200510046099 adopts the materials such as a kind of in inorganic colourant in a kind of and colouring agent in the adhesive that a kind of and base-material in a kind of in a kind of and inorganic acid or the organic acid in a kind of in inorganic stabilizers in a kind of in cationic and anionic and amphoteric ion type and the nonionic emulsifier in a kind of and emulsifying agent among a kind of and modifier EVA or SBR or the SBS in colourless cementitious matters or color asphalt or the decolouring pitch or two kinds and the auxiliary agent or the organic stabilizer or two kinds or three kinds and the surfactant or two kinds and caustic soda or the soda ash melts mutually and the toner or two kinds and water under specific equipment and process condition, and the employing modern crafts are made with extra care and formed. In the technical formula of coloured modified emulsified asphalt, do not add properties-correcting agent, promptly make color emulsified asphalt.It is applicable to that seal, Modified Slurry Sealing, slurry seal, little table place and the roof waterproof etc. on colored street road locate to use.Chinese patent 200410051266 discloses a kind of emulsification chromatic bituminous cement and preparation method, the emulsification chromatic bituminous cement is that color asphalt grinds the uniform suspension liquid that makes through emulsification under emulsifying agent, water, function of stabilizer, the emulsification chromatic bituminous cement comprises following four kinds of components:color asphalt, emulsifying agent, stablizer and water, wherein color asphalt accounts for mass percent 50~60%, emulsifying agent 0.8~2%, water 40~50%, stablizer 0.05~0.2%.The problem that above patent exists is prepared emulsified bitumen or exists softening temperature on the low side, or has the isolating shortcoming of storage.
