Definitions
- the invention relates to a bituminous emulsion with controlled viscosity, a composition of emulsifying agents and a method of manufacturing a bituminous emulsion. It has applications in the production of bitumen-based emulsions, for use in road techniques, civil engineering or in industrial jobs.
- bitumen emulsions for the production of road surfaces.
- the implementation, for this purpose, is currently done by spreading or coating. Before use, these emulsions must be able to be stored in tanks. So that the implementation of the emulsion is done in good conditions, in particular to avoid that run-offs on declivity roads, assembly roads for example, or simply curved, cause a spill of the emulsion on the bottoms sides or do not cause inhomogeneities of the coating and also so that storage can be done over long periods without risk of sedimentation of the emulsion particles and without the need for agitation of the emulsion, the viscosity of the bituminous emulsion must be high enough.
- bitumen content is not economically attractive.
- manufacturing becomes difficult and it is in practice necessary to work under pressure.
- bitumen concentration specifications which are often imposed limit the possibilities of acting on this parameter.
- the object of the present invention is to propose means allowing the production of a bituminous emulsion having a high and controlled viscosity without the above-mentioned drawbacks.
- the invention relates to a bituminous emulsion with controlled viscosity comprising an organic phase, oil type and an aqueous phase, water type and emulsifying agents in which the following means are used, said means being able to be combined in various embodiments technically possible:
- a first type of emulsifier promotes the oil-in-water type emulsion.
- a second type of emulsifying agent promotes the emulsion type water in oil.
- the organic phase forms particles within the aqueous phase, said particles can include within them one or more aqueous phases, the fraction of water included being between 1% to 15% of the total water.
- the first type of emulsifying agent is cationic.
- the second type of emulsifying agent is non-ionic.
- the cationic emulsifying agent is chosen from alkyl diamine salts, alkyl polyamine salts, alkylpolyaminoamide salts, quaternary ammonium salts with a fatty chain, etc.
- the nonionic emulsifying agent is chosen from the family of ethoxylated fatty alcohols, the hydrophobic part of the molecule can be of the nonylphenol-, octylphenol-, cetyl, oleic type, the hydrophilic part consisting of several ethoxy groups.
- the emulsion may also contain one or more acids.
- the emulsion may also contain one or more salts.
- the invention relates to a composition of emulsifying agents in which the following means are used to control the viscosity of bituminous emulsions comprising a fraction of water included between
- composition of emulsifying agents comprises a cationic agent and a nonionic agent.
- the cationic agent is chosen from alkyl diamine salts, alkyl polyamine salts, alkylpolyaminoamide salts, quaternary ammonium salts with a fatty chain, etc.
- the nonionic agent is chosen from the family of ethoxylated fatty alcohols, the hydrophobic part of the molecule possibly being of the nonylphenol-, octylphenol-, cetyl, oleic type, etc., the hydrophilic part consists of several ethoxy groups.
- the composition may also contain one or more acids.
- the composition may also contain one or more salts.
- the invention relates to a process for manufacturing bituminous emulsion with controlled viscosity, in which the following means are used, said means being able to be combined in various technically possible embodiments:
- the manufacturing process includes the following steps: a first aqueous phase comprising water, one or more cationic emulsifiers, which may comprise one or more soluble nonionic emulsifiers, is carried out; a second heated anhydrous phase, which may include one or more nonionic emulsifiers, is carried out; the two phases are introduced into a colloid mill, the fraction of water included is between 1% to 15% of the total water.
- the cationic emulsifiers are chosen from alkyl diamine salts, alkyl polyamine salts, alkylpolyaminoamide salts, quaternary ammonium salts with a fatty chain
- the nonionic emulsifiers are chosen from the family of ethoxylated fatty alcohols, the hydrophobic part of the molecule being able to be of nonylphenol-, octylphenol-, cetyl, oleic type ..., the hydrophilic part consists of several ethoxy groups.
- a first emulsion A is produced, it is a cationic bitumen emulsion of a conventional type, the bitumen level, grade 180/220, is 69% and the cationic emulsifier is a dodecylamine at a concentration of 65 mmol / l of aqueous phase, hydrochloric acid being added for salification.
- a second emulsion B is produced, it is an emulsion of non-ionic bitumen, the bitumen rate, grade 180/220, is 69%, and the nonionic emulsifier of the 25 mole ethoxylated cetostearyl alcohol type is at a concentration of 30 mmol / l of aqueous phase.
- a third emulsion C is produced, it is an emulsion of bitumen, of the mixed cationic and nonionic type according to the invention, the level of bitumen, grade 180/220, is 69%, the cationic emulsifier is a dodecylamine with a concentration of 50 mmol / l of aqueous phase, the salification being obtained with hydrochloric acid, and a nonionic emulsifier of the ethoxylated cetostearyl alcohol type at 25 moles is at a concentration of 20 mmol / l of aqueous phase.
- a fourth emulsion D is produced, it is an emulsion of bitumen, mixed cationic and nonionic emulsion according to the invention, the bitumen content, grade 180/220, is 69%, the cationic emulsifier being a dodecylamine is at a concentration of 50 mmol / l of aqueous phase, the salification being obtained with hydrochloric acid, and a nonionic emulsifier of the ethoxylated cetostearyl alcohol type at 25 moles is at a concentration of 30 mmol / l of aqueous phase.
- a fast-breaking emulsion usually has an IREC ⁇ 80.
- the weakly viscous control emulsion A has good characteristics. breaking and adhesiveness.
- the control emulsion B is viscous but not very adhesive.
- Emulsions C and D have very good characteristics resulting from the combination of properties linked to the cationic and nonionic characteristics of the emulsion: adhesiveness, rapid rate of rupture of the emulsion, high viscosity. The characteristics are therefore much superior to the simple addition of the results produced independently by the emulsifiers.
