A modified emulsified asphalt relates to a modified emulsified asphalt product obtained by modifying petroleum asphalt with an emulsifier, and the modified emulsified asphalt comprises the following components in percentage by weight: 55-65% of asphalt, 1.0-4.0% of petroleum acid quaternary ammonium salt cationic emulsifier, 1.5-5.0% of cationic styrene-butadiene rubber latex or a mixture of one or two of cationic styrene-butadiene-styrene triblock copolymer latex and 32-42% of water.
Description
Technical field
The present invention relates to modified oil pitch, particularly a kind of modified emulsifying asphalt product that adopts emulsifying agent that petroleum pitch is carried out modification and obtain.
Background technology
Along with the prolongation of China's expressway construction and working life, the maintenance work of motorway has become the major tasks of highway in China department.Modified emulsifying asphalt is a kind of emulsified asphalt product that adds rubber latex family macromolecule polymkeric substance; Both drawn the rubber asphalt properties of materials; The advantage that is keeping emulsified bitumen again makes the weathering resistance of emulsified bitumen improve elasticity, cohesiveness, toughness and the enhancing of anti-ageing property; Simultaneously can improve high-temperature stability, low-temperature cracking-resistance, force of cohesion, adhesivity, antistripping ability, early strength, the water resistance at little table place, thereby prolong its work-ing life.Modified emulsifying asphalt can be widely used in the making and routine servicing engineering of advanced road, and especially the treatment process at the little table of maintenance of surface place must use the modified emulsifying asphalt product, and its technical feature quality will directly influence the success or failure of little table place technology.
By introducing in " production of petroleum pitch and application " book that people such as Zhang Deqin write, Sinopec press publishes, at present, the kind of domestic modified emulsifying asphalt is a lot, and the preparation method of modified emulsifying asphalt has three kinds.First method is called the hot hybrid system of secondary, and promptly rubber latex is through twice hot blending dispersion process.Second method is called once hot hybrid system, and promptly rubber latex and bitumen emulsion are through hot blending dispersion process once.The third method is called the cold mixing method one time, and promptly rubber latex and bitumen emulsion are through a cold mixing dispersion process.This several method all exists the emulsion instability, aspect defectives such as emulsifying agent poor performance.
Fine modified emulsifying asphalt product requires to possess simultaneously dispersion stabilization and two kinds of character of breakdown of emulsion coherency in practical applications, emulsifying agent, performance and compatibility material modified and used bituminous material are the key factors of decision modified emulsifying asphalt quality.ZL02160143.7, ZL02160144.5,02160148.8 and 02160155.0 disclosed emulsified modified asphalt preparation method; After perhaps earlier properties-correcting agent latex directly being joined in the matrix pitch fully mixing; Make modified emulsifying asphalt with the emulsifier solution mixing and emulsifying again, perhaps earlier with properties-correcting agent latex and emulsifier solution thorough mixing even after, be heated to certain temperature; Pass through the mulser mixing and emulsifying with matrix pitch again; Behind the mechanical stirring froth breaking, make modified emulsifying asphalt, after perhaps earlier pitch and emulsifier solution being mixed, make emulsified bitumen through the mulser mixing and emulsifying; Then properties-correcting agent latex is added to mix in the emulsified bitumen and make modified emulsifying asphalt; Perhaps make modifying asphalt with adding properties-correcting agent in the matrix pitch earlier, in modifying asphalt, add emulsifying agent again, make emulsified modified asphalt behind the mixing and emulsifying.Mentioned emulsifier employing quaternary ammonium salts or wooden amine, carboxamido-group polyamines class, imidazolines, properties-correcting agent adopts styrene-butadiene latex or polychloroprene latex, B-S-B latex etc.But because preparation technology utilizes hydrochloric acid to improve the reactive behavior and the increase package stability of emulsifying agent, thus there is equipment corrosion, problem of environmental pollution, and there is labile factor in product.
Application number 200510077107.7 adopts papermaking wastewaters as emulsifying agent, and add stablizer, the crosslinking reaction agent makes a kind of high performanced composite emulsifying modified asphaltum material, its preparation process is comparatively complicated; ZL02122841.8 discloses a kind of polymer emulsified and re-cross-linked asphalt colloid mixture, and its preparation process need add dispersion agent and stablizer; 90107907.3, adopt yin, yang ion or nonionogenic tenside compound system to prepare emulsified bitumen, but pitch do not carried out modification with the emulsified bitumen that 200310104916.3 applications relate to.
Summary of the invention
Order of the present invention is to be to provide a kind of modified emulsifying asphalt product; Each item technical indicator of this product all satisfies the technical requirements of the modified emulsifying asphalt among the JTGF40-2004; Has excellent storage stability; With building stones good adhesion characteristic, can be widely used in the surface abrasion layer of newly-built road and the maintenance of old pavement.
For realizing above purpose; Technical scheme provided by the invention is: a kind of modified emulsifying asphalt; Modified emulsifying asphalt is made up of following component by weight percentage: 55～65% pitch; 1.0～4.0% petroleum acid quaternary ammonium salts cationic emulsifier, the mixture of one or both products of 1.5～5.0% positively charged ion styrene butadiene rubber latex or cationic styrene-butadiene-styrene ternary block polymer latex, 32～42% water.
Described pitch is one or more bituminous mixtures in oxidized bitumen, solvent deasphalting or the heavy traffic paving asphalt.25 ℃ of penetration degree scopes of said bituminous are controlled at 40～150 (0.1mm).
The molecular weight of petroleum acid quaternary ammonium salts cationic emulsifier is 300～550, and the HLB value is 10～14.For the sub product petroleum acid in the naphthenic base crude course of processing is the quaternary ammonium salts cationic emulsifier of feedstock production.
Described polymer modifiers is that the solid content of positively charged ion styrene butadiene rubber latex or cationic styrene-butadiene-styrene ternary block polymer latex is 20～60%.
The concrete preparation process of modified emulsifying asphalt product is following: (1) can sequentially join 1.0～4.0% the weight of emulsifier and 1.5～5.0% weight polymer properties-correcting agent in 32～42% weight water in no particular order, and it is for use under 40～80 ℃ of temperature, to stir 0.5～3 hour thorough mixing; (2) with 55～65% weight matrix pitches be heated to 130～160 ℃ for use; (3) first mixed aqueous solution with 40～80 ℃ joins in the colloidal mill and circulates; The matrix pitch that slowly adds 130～160 ℃ then; Treating that whole pitches add in rotating speed is 3000～5000 rev/mins colloidal mill finishes, and mixture recycling 1 minute can make the modified emulsifying asphalt product.
Technology of the present invention is simple, and is easy to operate, and etching apparatus can not produce the three wastes, environmentally safe.The modified emulsifying asphalt product of preparation, character meets the modified emulsifying asphalt technical requirement of the JTG F40-2004 of The Ministry of Communications's " highway Modified Bitumen Pavement construction technique normalizing " fully, has good adhesivity, excellent storage stability with building stones.Product is because to adopt the sub product petroleum acid in the naphthenic base crude course of processing be feedstock production quaternary ammonium salts emulsifying agent, thereby itself and matrix pitch have better compatibleness, and emulsifying effectiveness is better, and product performance are very stable.The component that the used matrix pitch of product obtains owing to the processing of employing naphthenic base crude, thus better by its modified emulsifying asphalt product low-temperature performance of preparing.
