Definitions
- the present invention relates to the field of bituminous products that can be used for the production of road surfacing, and more particularly to surface-type coatings. More specifically, the invention relates to compounds which are found to be well suited as fluxing agents of the hydrocarbon binder in the preparation of surface hot coatings.
- Coatings type "surface coating” (“surface dressing” in English) are a special family of products called “bituminous”, used for example for road applications, which contain mineral particles (also referred to as “aggregates") secured between they by a hydrocarbon binder, which can in particular be a bitumen, hence the generic term “bituminous” product used in the broad sense, including when the binder is not a bitumen.
- bituminous Solidarization of the particles in so-called “bituminous” products is typically achieved by "embedding" the particles in the hydrocarbon binder, whereby a so-called bituminous mix is obtained.
- the bonding is obtained by a less intimate contact between the mineral particles and the binder.
- the term "superficial coating” is understood in its common meaning in the field of road surfaces, namely that it designates a bituminous product comprising at least one layer formed by (i) a first layer including a hydrocarbon binder (often with additives such as polymers or fluxes), on which is deposited (ii) a second layer comprising inorganic solid particles (aggregates).
- This layer with two layers is typically a wearing course, with the layer of aggregates intended to be in contact with the traffic.
- a surface coating type coating may optionally be coated, for example by a new layer of surface coating.
- the concept of "superficial" coating in the sense of the present description is not limited to only wearing courses and also includes coatings that are intended to be covered later.
- a surface coating is typically obtained by producing a layer of hydrocarbon binder (typically by spraying), then spreading on this binder inorganic solid particles in one or more layers. In general, the assembly is then compacted.
- the present invention is more specifically concerned with so-called "hot” surface coatings, as opposed to “cold” surface coatings which employ a binder hydrocarbon emulsion form and can therefore be used at a relatively low temperature.
- the hydrocarbon binder is not in the form of an emulsion, it must be used at a temperature sufficient to allow the application of the layer where the aggregates will then be deposited.
- the hydrocarbon binder is typically applied at a temperature of at least 120 ° C. and generally below 200 ° C., generally between 120 and 180 ° C. ° C, especially between 130 and 160 ° C
- the adhesiveness must indeed be sufficient to secure the aggregates on the hydrocarbon binder layer, which is particularly critical with the coatings where the binder does not completely imprison aggregates, unlike the case of asphalt.
- a superficial coating therefore requires the use of a binder which must at the same time:
- Hydrocarbon binders that are used in bituminous products are very viscous products, which, especially when they are not used in emulsion form, most often require the use of additives in addition to their heating.
- additives of this type known as "fluxing", of petroleum, petrochemical, carbochemical or even vegetable origin have been proposed in the past, which make it possible, among other things, to reduce the viscosity of hydrocarbon binders.
- the fluxing agents added to the hydrocarbon-based binder in the particular case of a superficial hot coating must, schematically, make it possible to "soften” the binder sufficiently to allow its application, but neither too much nor too little, so as not to penalize thereafter. attaches aggregates by the binder:
- This pseudoviscosity corresponds to the flow time of 50 ml of the hydrocarbon binder considered (which may contain additives such as polymers or fluxes) at a temperature of 40 ° C. through a 10 mm orifice, measured in the conditions defined in standard NF EN 12846-2 (April 201 1).
- a binder having a pseudo-viscosity STV of 300 seconds (generally too fluid if the pseudo-viscosity STV is lower) and 500 seconds (generally not sufficiently fluid) is preferably employed. beyond this value) at the time of contacting the binder and aggregates.
- the affinity between the binder and the aggregates in a bituminous product of the surface-coating type can be quantified by the possibility of wetting the inorganic solid particles by the binder and by the capacity of the binder to retain the aggregates, according to the method of determining the Binder-aggregate adhesiveness by Vialit cohesion measurement as defined in standard NF EN 12272-3 (July 2003).
- Vialit test The method of measuring Vialit cohesion (referred to here as "Vialit test” conciseness) is described in detail in the above-mentioned standard, in the July 2003 version, to which reference may be detail of the precise conditions, calibrated, to implement to carry out the test.
- This Vialit test consists in summary to: apply uniformly on a steel plate the hydrocarbon binder to be tested, at the spraying temperature (spreading) used to carry out the coating; then;
- hydrocarbon binder (which may or may not include additives) is satisfactory for producing a superficial coating if, by carrying out the Vialit test at a temperature of 5 ° C. (+/- 1 ° C.), a number c of glued gravel greater than or equal to 50.
- the standard NF EN 12272-3 is concerned with the number b + c (referred to as "adhesivity value" in the standard) which mainly reflects the wetting capacity of aggregates by bitumen.
- adheresivity value mainly reflects the wetting capacity of aggregates by bitumen.
- the number of particles that remain bound to the plate is more relevant insofar as it reflects the ability of the coating to withstand the application conditions.
- hydrocarbon binder is tested in accordance with the Vialit test with a Vialit test temperature of 5 ° C (+/- 1 ° C) so as to ensure that the binder tested will be usable in the the most drastic weather conditions.
- a hydrocarbon binder can be quite satisfactory even if it does not achieve a higher or equal number c at 50 for a Vialit test at 5 ° C. This is the case if it can make it possible to achieve this number of bonded chippings c greater than or equal to 50 for a slightly higher test operating temperature, for example at 10 ° C.
- Vialit test temperature corresponds to the temperature of the climatic chamber where the Vialit test is carried out, which is to be distinguished for example from the temperature of the binder, which is higher.
- T 50 the minimum temperature of the Vialit test for which a number of bonded chippings c of at least 50 will be defined under the conditions defined in standard NF EN 12272, will be defined by T 50.
- T 50 the minimum temperature of the Vialit test for which a number of bonded chippings c of at least 50 will be defined under the conditions defined in standard NF EN 12272.
- - T 50 is less than or equal to 15 ° C, more preferably less than or equal to 10 ° C, and ideally less than 5 ° C;
- the ⁇ 60 is preferably less than or equal to 20 ° C, more preferably less than or equal to 15 ° C, and ideally less than
- the T 70 is preferably less than or equal to 25 ° C, more preferably less than or equal to 20 ° C, and ideally less than 15 ° C, or even 10 ° C
- the binder must contain a fluxing agent.
- An object of the present invention is to provide a method for modifying the properties of hydrocarbon binders, in particular so as to lower their T 50 in ranges suitable for producing hot surface coatings.
- the present invention proposes the use of novel additives as fluxing agents in hydrocarbon binder compositions.
- the "petrochemical fluxing agents” derived from the distillation of crude oil (light fraction (s)), with thermal cracking and / or complementary distillation, such as, for example, the Adheflux ⁇ fluxing agents marketed by VFT France.
- a natural non-fossil fluxing agent is a non-fossil natural oil, one of its derivatives such as fatty acid esters, or a mixture of two or more of these oils and / or oil derivatives.
- vegetable oils such as sunflower, rapeseed, peanut, coconut, flax, palm, soybean, olive, castor oil, maize, squash, pomaceous seed oil may be mentioned.
- oils mainly comprise at least 6 unsaturated fatty acids.
- fluxing agents are for example described in the applications FR 2 910 477, EP 0 900 822, FR 2 721 043 or FR 2 891 838.
- the increase in consistency of the binder in the final product is not done by evaporation, unlike in the case of volatile fluxes, but rather by crosslinking, typically following radical reactions, unsaturated fatty chains reacting in the presence of oxygen in the air.
- These reactions which can be catalyzed by the addition of drying agents such as metal salts, include the formation of peroxide bridges on the unsaturated chains.
- the fluxant is selected from the iodine number which characterizes the unsaturation rate of a compound and therefore its ability to react by sicActivtion.
- non-volatile fluxes of non-fossil natural origin are, however, less satisfactory than petroleum-based fluxes in terms of results. Indeed, the results of rise in cohesion are less good. They lead most often to disorders in case of showers, heats or traffic too dense, problems of ressuages, glued in particular to poor adhesion of the hydrocarbon binder fluxed on the mineral solid particles.
- the present invention proposes to implement particular compounds, which the inventors have now identified as being: (1) compounds that behave as volatile fluxes, interesting in that they allow, once incorporated into compositions comprising a hydrocarbon binder and before their evaporation, to reduce the viscosity of the hydrocarbon binder, but without the disadvantages of the usual volatile fluxes; and (2) compounds suitable for the preparation of hot surface coatings.
- R 1 and R 2 which may be identical or different, are linear or branched C 1 -C 11 hydrocarbon-based chains;
- the methyl compounds of formula (A) in which CH 3 for which an incorporation at a level of 10% by weight in a hydrocarbon-based binder leads to an STV pseudo-viscosity of greater than 500 seconds can not be used for the production of superficial coatings with the binder in question.
