- the compositions thus obtained are then either calendered in the form of plates (thickness of 2 to 3 mm) of rubber for the measurement of their mechanical properties, or extruded in the form of a semi-finished product for a tire, for example a web. rolling.
- the vulcanization (cooking) is carried out at 150 ° C. for 40 min, under pressure.
- the purpose of this test is to compare the performances of the two compositions according to the invention (respectively denoted C-3 and C-4) incorporating the charges A and B, to the composition not according to the invention (denoted C-5 ) incorporating the control charge C.
- the three compositions are for example intended for tire treads.
- Tables 3 and 4 give successively the formulation of the various compositions (Table 3 - rates of the different products expressed in phr), their properties before and after baking at 150 ° C. for 40 minutes (Table 4).
- the functionalized PVAr filler represents approximately 97% (% by volume) of the totality of the reinforcing filler, the latter additionally comprising a very small proportion (2 phr) of carbon black.
- Figure 4 reproduces the curves of true secant modulus (in MPa) as a function of elongation (in%); these curves are denoted C3, C4 and C5 and respectively correspond to rubber compositions C-3, C-4 and C-5.
- the radical emulsion polymerization is carried out in a buffered medium (pH equal to 7), with simultaneous introduction into a reactor of styrene, MTSP (Aldrich product), and a mixture of DVB and EVB (product DVB Fluka); said mixture was first washed 3 times with 1M aqueous sodium hydroxide solution and then washed with water until neutral pH.
- the various monomers are previously subjected to nitrogen sparging, as well as the aqueous solutions used with the exception of the solution of SDS (bubbling in the form of powder).
- the reaction is conducted in a 30 liter reactor equipped with mechanical stirring.
- the physicochemical characteristics of the charge latex thus prepared are substantially identical to those found for the product synthesized on a smaller scale (Test 1).
- the analysis shows that the nanoparticles (elementary particles) are in the form of nanobeads which have in majority a diameter of between 20 and 60 nm (mean circular diameter of about 30 nm).
- the density of the charge, measured on powder, is equal to 1.1 g / cm 3 .
- the PVAr loading latex is then added to an SBR latex (21.5 l of 216 g / l SBR latex) to reach a
- the resulting mixture is gently homogenized; at this stage, an antioxidant may be added in particular (dissolved for example in a suitable solvent such as toluene), for example in the form of an aqueous emulsion.
- an antioxidant may be added in particular (dissolved for example in a suitable solvent such as toluene), for example in the form of an aqueous emulsion.
- the mixture is then added to 168 l of strongly stirred methanol for precipitation of the masterbatch.
- the precipitate thus obtained is filtered, rinsed with water until constant residual foaming of the washings and negative test of silver nitrate washings.
- the masterbatch thus washed is dried under reduced pressure under nitrogen at 60 ° C. for 2 days.
- composition C-6 silica HDS (control); composition C-7: MTSP functionalized PVAr.
- the rate of reinforcing filler was adjusted to iso-fraction by volume of filler (same volume - ie about 19% - of filler in each composition). Due to the reduced density of the organic filler, the density of composition C-7 is markedly reduced (1.01 g / cm 3 instead of 1.19 g / cm 3 ). As the specific surface of the polymer filler is lower, the amount of TESPT coupling agent introduced into the composition C-7 is therefore lower.
- Tables 5 and 6 successively give the formulation of the different compositions. (Table 5 - rates of the various products expressed in phr), their properties after cooking at 150 ° C. for 40 minutes (Table 6).
- compositions similar to compositions C-6 and C-7 above were compared as
- the composition according to the invention has revealed a noticeable decrease (improvement) of 9.5% in rolling resistance, thus confirming the appreciable gains in hysteresis observed at the laboratory stage. In addition, and just as unexpectedly, there was an increase (improvement) of 13% in
- Test 2 (30-liter reactor) is incorporated into a rubber composition in the form of a masterbatch obtained by coprecipitation of the PVAr-loading latex and a latex of natural rubber (NR). Said composition, according to the invention, is finally compared to a NR-based control rubber composition and conventionally loaded with HDS silica.
- the PVAr filler latex is incorporated into natural rubber to obtain a masterbatch.
- the PVAR loading rate referred to in the masterbatch, as in the final rubber composition, is 39 phr.
- the amount of dry matter in the NR latex is determined by weighing, on dry extract. Before preparing the masterbatch, the NR latex is then diluted with water to a content of 200 g / l of NR.
- the diluted and cooled at room temperature PVAR loading latex is added to the diluted NR latex in a proportion of 39 phr of filler (ie 23 l of 200 g / l NR latex). Then 64 g of antioxidant (N- (1,3-dimethylbutyl) -N'-phenyl-p-phenylenediamine) is added as an aqueous emulsion and the resulting mixture is gently homogenized. At the rate of 2 l / min, this mixture is then added to 168 l of strongly stirred methanol for precipitation of the masterbatch.
- antioxidant N- (1,3-dimethylbutyl) -N'-phenyl-p-phenylenediamine
- the precipitate thus obtained is filtered off, rinsed with water and then the methanol is removed by steam distillation.
- the masterbatch is then washed with water to remove the surfactant and the buffer salts, by several successive dilution cycles and settling until constant residual low foaming of the washings and negative test of the silver nitrate washings.
- the masterbatch thus washed is filtered and then dried under reduced pressure (under nitrogen) at 60 ° C. for 2 days.
- composition C-8 control: silica HDS
- composition C-9 invention: MTSP functionalized PVAr.
- such rubber compositions are typically used in the parts of ground-engaging systems, in particular of tires, usually using NR-based rubber matrices, such as, for example, the internal supports of safety for tires, flanks, bead areas pneumatic tires, the underlays of treads as well as the treads of these tires, particularly for heavy goods vehicles.
- NR-based rubber matrices such as, for example, the internal supports of safety for tires, flanks, bead areas pneumatic tires, the underlays of treads as well as the treads of these tires, particularly for heavy goods vehicles.
- the degree of reinforcing filler was adjusted to iso-fraction by volume of filler (same volume - ie approximately 17% - filler in each composition). As the specific surface of the polymer filler is lower, the amount of TESPT coupling agent introduced into the composition C-9 is therefore much lower.
- the PVAr feedstock represents approximately 97% (by volume) of the totality of the reinforcing filler, the latter comprising a small proportion (1 phr) of carbon black.
- Tables 7 and 8 give successively the formulation of the various compositions (Table 7 - rates of the various products expressed in phr), their properties before and after baking at 150 ° C. for 30 minutes (Table 8).
- Figure 5 reproduces true secant modulus curves (in MPa) as a function of, elongation (in%); these curves are denoted C8 and C9 and correspond to compositions C-8 and C-9, respectively.
- FIG. 5 confirms the above results: it can be seen that the curve C9 is situated clearly above the curve C8 for the strongest deformations, the difference between the two curves being accentuated as the elongation increases; this illustrates a high level of reinforcement offered by the PVAr feed, at least equal if not greater than that offered by the reference HDS silica;
- the specific polymer load of the composition according to the invention thanks to its very greatly reduced density compared to a conventional reinforcing filler such as carbon black or HDS silica, makes it possible to very substantially reduce the weight of said composition.
- This objective is achieved not only without degradation of the reinforcement, synonymous with resistance to wear or cracking, compared to these conventional loads, but also allowing a significant reduction in hysteresis, synonymous with rolling resistance or further enhanced heating over a conventional reinforcing inorganic filler such as HDS silica.
- the density of the composition of the invention substantially becomes equal to that of the charge polymer itself, it becomes possible to increase the reinforcing filler without increasing the density of the rubbery matrix.
