Definitions
- the present invention belongs to the field of bitumens, in particular in the field of bitumen / elastomer compositions. More specifically, the invention relates to a crosslinking composition for bitumen / elastomer compositions, in granule form, for preparing crosslinked bitumen / elastomer compositions having reduced hydrogen sulfide emissions. The invention also relates to the process for the preparation of crosslinked bitumen / elastomer compositions using the crosslinking compositions in the form of a granule, a process in which the hydrogen sulphide emissions are reduced.
- US Pat. No. 7,402,619 describes a crosslinking composition that can be in the form of a granule or a powder.
- This crosslinking composition comprises from 5 to 50% of elemental sulfur, from 0.5 to 10% of sulfur derivatives, from 5 to 50% of zinc derivatives, from 5 to 50% of fatty acid derivatives and from 10 to 85% of polymeric matrix.
- the amount of zinc in the crosslinking composition is at least 2% by weight and the mass ratio between the amounts of zinc and sulfur is between 0.5: 1 and 2: 1. relative to the amount of sulfur makes it possible to reduce the hydrogen sulphide emissions during the preparation of bitumen / elastomer compositions using this crosslinking composition.
- This crosslinking composition is however not satisfactory and has several disadvantages.
- the invention also relates to the use of the granular crosslinking composition as defined above, for reducing hydrogen sulphide emissions during the preparation of crosslinked bitumen / elastomer compositions.
- the amount of crosslinking composition in granule form as defined above is between 0.05% and 5% by weight, relative to the total composition bitumen / elastomer / crosslinking composition in granule form, preferably between 0.1% and 2%, more preferably between 0.15% and 1%, even more preferably between 0.2% and 0.5%.
- the ratio between the amounts of sulfur and elastomer is between 0.005 and 0.05, preferably between 0.01 and 0.03, more preferably between 0.02 and 0.025.
- the crosslinking composition according to the invention is in the form of a granule and comprises at least one polymeric matrix, at least one crosslinking agent and at least one hydrogen sulphide inhibiting agent, the hydrogen sulphide inhibiting agent comprising at least one carboxylate of zinc and at least one derivative of the triazine.
- the amount of zinc carboxylate in the granular crosslinking composition is 5% to 50% by weight, based on the weight of the crosslinking granular composition, preferably 10% to 40%, more preferably preferably between 20% and 30%. The interval between 10% and 20% is preferred.
- This amount of zinc carboxylate is an ideal compromise with respect to the amounts of crosslinking agent and polymeric matrix of the crosslinking composition in granule form. This makes it possible at the same time to sufficiently trap the hydrogen sulphide emissions, to sufficiently crosslink the bitumen / elastomer composition and to have a granule that can be handled and stable.
- a lower amount of zinc carboxylate is not suitable because a certain amount of zinc carboxylate is required in the pellet to trap the hydrogen sulfide released.
- a higher amount of zinc carboxylate does not make it possible to formulate a granule allowing both good crosslinking and easy handling, since this would imply reducing the amounts of crosslinking agent and / or polymeric matrix.
- the zinc carboxylate according to the invention comprises a quantity of zinc of between 5% and 30% by weight, relative to the weight of zinc carboxylate, preferably between 10% and 20%.
- the amount of zinc in the crosslinking composition in the form of a granule is limited, in particular because of the low zinc content of the zinc carboxylates.
- derivative of triazine is meant derivatives of 1, 2, 3-triazine, 1, 2, 4-triazine and 1, 3, 5-triazine (or s-triazine). Hydrated derivatives of triazine are preferred.
- the alkyl and / or hydroxalkyl substituents comprising from 1 to 12 carbon atoms, preferably from 2 to 8 carbon atoms, are preferred.
- the mass ratio between the amounts of zinc carboxylate and triazine derivative is therefore preferably greater than or equal to 1, or even greater than 1.
- the amount of crosslinking agent in the granular crosslinking composition is between 5% and 50% by weight, based on the weight of the crosslinking composition in granular form, preferably between 10% and 40%, more preferably between 20% and 30%.
- the amount of crosslinking agent is adjusted in depending on the amount of elastomer to be crosslinked in the bitumen / elastomer composition.
- the amount of crosslinking agent must be sufficient to allow the crosslinking of any elastomer present in the bitumen / elastomer compositions to be crosslinked.
- the crosslinking agent comprises sulfur in combination optionally with vulcanization accelerators.
- This amount of sulfur represents the amount of sulfur in bloom in the crosslinking composition in granule form.
- the sulfur present in the vulcanization accelerators is not taken into account.
- the quantity of sulfur in the granule is preferably chosen so as to obtain a mass ratio between the amounts of zinc (zinc carboxylate and vulcanization accelerators when they are present) and sulfur between 0.01 and 0, 3, preferably between 0.02 and 0.2, more preferably between 0.04 and 0.1, even more preferably between 0.05 and 0.08. Contrary to what was advocated in the prior art, the ratio between the amounts of zinc and sulfur of the crosslinking composition in granule form according to the invention is very low, but it is sufficient, in combination with the triazine derivative. , to trap a significant amount of hydrogen sulfide.
- the quantity of vulcanization accelerators in the granule is preferably chosen so as to obtain a mass ratio between the amounts of vulcanization accelerators and sulfur of between 0.02 and 0.10, preferably between 0.03 and 0.08, more preferably between 0.05 and 0.06.
- the vulcanization accelerators comprise a quantity of zinc of between 5% and 30% by weight, relative to the mass of the vulcanization accelerators, preferably between 10% and 20%, more preferably around 15%.
- the latter In order to be able to form the crosslinking composition in the form of a granule, the latter must comprise a polymeric matrix, which makes it possible to bind together the various constituents of the granule.
- This polymeric matrix allows extrusion forming in the form of a granule.
- the polymeric matrix preferably comprises a plastomer.
- This plastomer is preferably a plastomer comprising ethylene units.
- the polymeric matrix is chosen from polyethylenes (PE), ethylene / propylene copolymers, ethylene / acrylic ester copolymers, ethylene / glycol monostearate copolymers, ethylene / vinyl acetate copolymers (EVA), taken alone or as a mixture .
- the amount of polymeric matrix in the granule is between 5% and 50% by weight, relative to the weight of the crosslinking composition in granule form, preferably between 10% and 40%, more preferably between 20% and 30%. %.
- a larger amount of polymeric matrix is undesirable because it does not interfere with the elastomeric crosslinking and hydrogen sulfide inhibition processes (it only serves to shape the crosslinking composition in pellet form). It is therefore sought to limit the amount of polymeric matrix as much as possible, the limit being obviously the shaping in the form of a granule.
- the granule composition according to the invention comprises:
- the invention also relates to the use of the crosslinking compositions in granule form according to the invention, for preparing crosslinked bitumen / elastomer compositions.
- the use of the crosslinking compositions in granule form according to the invention makes it possible to crosslink bitumen / elastomer compositions with reduced hydrogen sulphide emissions.
- the preferred elastomer is a copolymer of styrene and butadiene such as styrene / butadiene (SB) block copolymer or styrene / butadiene / styrene copolymer (SBS).
- SB styrene / butadiene
- SBS styrene / butadiene / styrene copolymer
- the styrene-butadiene copolymer advantageously has a weight content of butadiene (1-2 and 1-4) ranging from 50 to 95%.
- bitumen / elastomer / crosslinking composition in granule form between 2% and 10%, more preferably between 3% and 5%.
- elastomer between 0.05% and 5% by weight of crosslinking composition in granule form according to the invention, relative to the total weight of bitumen / elastomer / crosslinking composition in pellet form, preferably between 0, 1% and 2%, more preferably between 0.15% and 1%, even more preferably between 0.2% and 0.5%.
- the range between 0.1% and 0.2% is preferred. It is preferred to use a lesser amount of crosslinking composition in pellet form.
- the crosslinking composition in granule form must therefore be as concentrated as possible in so-called active agents such as the crosslinking agent or the hydrogen sulphide inhibiting agent.
- the quantity of granular crosslinking composition to be introduced into the bitumen / elastomer composition is chosen such that the mass ratio of the amounts of sulfur and elastomer is between 0.005 and 0.05, preferably between 0.01 and 0.05. 0.03, more preferably between 0.02 and 0.025. This ratio is very important and allows optimal crosslinking of the elastomer. A ratio of less than 0.005 does not make it possible to crosslink all of the elastomer present in the bitumen / elastomer composition. The elastic properties of the bitumen / elastomer composition would be insufficient if this ratio was less than 0.005.
- the process for preparing the crosslinked bitumen / elastomer compositions comprises the following essential steps: (i) heating and mixing at least one bitumen between 160 ° C. and 200 ° C., preferably between 180 ° C. and 190 ° C., preferably between 5 minutes and 120 minutes, more preferably between 10 minutes and 60 minutes,
- This process for the preparation of crosslinked bitumen / elastomer compositions is particularly simple to implement because it involves only three components: bitumen, elastomer and the cross-linking composition in the form of a granule which includes all the components necessary for crosslinking and trapping of hydrogen sulphide.
- the invention finally relates to the use of the crosslinking composition in granule form as defined above for preparing crosslinked bitumen / elastomer compositions that can be used as bituminous binders in anhydrous form or in the form of an emulsion.
- This bituminous binder can be used in road applications as base course, tie layer, wearing course and / or in industrial applications as a waterproofing coating, membrane, impregnation layer.
- This bituminous binder can in particular, in combination with aggregates, be intended for the manufacture of surface coatings, hot mixes, cold mixes, cold mixes, serious emulsions.
- a linear block elastomer of styrene / butadiene / styrene type comprising a weight content of styrene of 31%
- the cross-linking compositions in the form of control granules do not comprise a hydrogen sulfide (Gi) inhibiting agent or comprise, as hydrogen sulfide-inhibiting agent, only a particular zinc carboxylate, zinc stearate (G 2 ) or zinc acetate (G3).
- the crosslinking compositions in pellet form are prepared by a traditional extrusion process. Standard techniques and devices are used. The extrusion temperature is below 110 0 C, preferably below 90 0 C. It can also perform a pre-mixture of hydrogen sulphide inhibitors when inhibitors is a powder at room temperature and other inhibitor a liquid at room temperature.
- crosslinking compositions in the form of granules are stable and manipulable.
- the crosslinking compositions in the form of granules have the compositions given in Table I (% by mass). Table I
- O np repairs various elastomer / bitumen compositions to C 6 respectively crosslinked with various vulcanizing compositions in the form of granulated Gi G 6 of Table I.
- the elastomer / bitumen compositions to C 6 are prepared as follows:
- a direct distillation bitumen as defined above is introduced into a hermetic reactor of 2 liters with stirring (300 revolutions / min) and at 185 ° C., it is heated for 10 minutes, an elastomer of the same type is added.
- styrene / butadiene / styrene as defined above
- the bitumen / elastomer mixture is heated at 185 ° C. for 4 hours
- the mixture is stirred at 300 rpm and heated at 185 ° C for 2 hours.
- the mass ratio of the amounts of sulfur and elastomer in the bitumen / crosslinked elastomers to C 6 is 0.02.
- Table III presents the physical characteristics of the crosslinked bitumen / elastomer compositions according to the invention, compositions C 4 , C 5 and C 6 respectively crosslinked with the crosslinking compositions in the form of granules G 4 , G 5 and G 6 and control crosslinked bitumen / elastomer compositions, compositions C 1 , C 2 and C 3 crosslinked respectively using the crosslinking compositions in the form of granules G 1 , G 2 and G 3 and a bitumen / non-control elastomer composition; reticulated Co.
- the set of vulcanizing compositions in the form of granule G 1 to G 6 makes it possible to cross-link the bitumen / elastomer compositions C 1 to C 6 . All of the elastomer present in these compositions is crosslinked. Indeed, it is found that the consistency of the crosslinked bitumen / elastomer compositions C 1 to C 6 is greater than that of the uncrosslinked bitumen / elastomer composition Co (see Penetration and Ball and Ring Temperature values). Similarly, the values obtained in the tensile test show that the crosslinked bitumen / elastomer compositions C 1 to C 6 are considerably more elastic than the non-crosslinked bitumen / elastomer composition C.
- the released hydrogen sulfide emissions are measured in the gas phase using a probe placed in the closed reaction medium, for 2 hours, from the introduction of the crosslinking composition in granule form in the bitumen / elastomer mixture.
- a curve gives the amounts of hydrogen sulfide released as a function of time.
- the curve corresponding to the crosslinked composition Ci using a granule not comprising a hydrogen sulfide inhibitor is considered as the reference curve.
- the percentages of reduction of the hydrogen sulphide emissions obtained during the crosslinking of the C 2 to C 6 bitumen / elastomer compositions, with respect to the C 1 reference, are shown in Table IV below: TABLE IV
- crosslinking compositions in granule form according to the invention therefore make it possible to obtain elastic crosslinked bitumen / elastomer compositions, while considerably reducing the hydrogen sulphide emissions.
