Definitions
- the present patent application for industrial invention relates to a compound for realization of modified bitumen.
- bitumen will be prevailingly used in the description below, it is understood that the present invention extends to the field of asphalts, in particular for road surfaces.
- Bitumens are complex thermoplastic products composed of very different elements: asphaltenes and malthenes. Bitumens have excellent adhesive properties, but poor mechanical properties, especially according to temperature. In fact, bitumens have a very low hardness at ambient temperature (25 °C). Moreover, at temperatures below 0 °C (cold), bitumens are rigid and fragile, whereas at temperatures above 38°C (hot), bitumens are plastic, soft and very adhesive. For this reason, bitumens cannot be used for most road or building applications.
- bitumens by means of chemical and polymer additives is extremely important in order to essentially modify the nature of bitumens, thus making modified bitumens suitable for the most diverse industrial uses.
- NBR Nitrile Rubber
- SBr Styrene-Butadiene-Rubber
- the environmental benefits derive from the possibility of using a material that can be hardly used in other activities and is available in large quantities, in highly technological applications, replacing elastomer polymers of high value and cost.
- bitumens that has been discovered recently relate to the use of a devulcanized variant of rubber granules.
- This variant allows for producing a portion of material with low molecular weight, soluble in bitumen or asphalt and allows for creating a surface of the residual granule more suitable for cohesion with bitumen, consequently improving the final mechanical characteristics.
- Such a technology is expensive and requires the use of specific equipment, such as pirolizers or extruders especially designed to obtain conversion from mechanical to thermal energy in order to achieve the temperatures that are necessary for resolution of intra and intermolecular bonds of vulcanized products.
- such a technology uses ground products from tires with very high granulometry.
- a process known as "dry process” is currently known for production of modified asphalt.
- Said process provides for using powders derived from grinding vulcanized products (generally tires) with size higher than 0.4 mm, and the replacement of part of mineral grit in asphalt with said powders.
- Said powders are also used to produce Rubber Asphalt obtained with wet process (in wet phase) to obtain bitumens with better rheological characteristics than basic bitumen.
- the asphalts and bitumens obtained with the known processes are not suitable to obtain the performance that is currently required by national or international specifications for specific applications in the road or building fields.
- bitumens modified with crumb rubber of recycled tires are impaired by compatibilization problems of crumb rubber with bitumen. Such an inconvenience is solved by using catalysts mixed in bitumen.
- WO2001 1 /074003 discloses the use of a catalyst for FCC (Catalytic Cracking) plant comprising oil and low value polymers, such as polyolefin polymers. Hence SBS is not a low value polymer.
- KHALDOUN "Effect of furfural activated crumb rubber on the properties of rubberized asphalt" describes the use of a furfural catalyst to improve adhesion of crumb rubber to bitumen.
- SBS thermoplastic block copolymers Styrene-Butadiene-Styrene
- said thermoplastic block copolymers (SBS) are the best performing ones in bitumen modification, allowing for achieving the desired characteristics of high temperature softening, penetration at ambient temperature, and low temperature flexibility.
- block copolymers can be used in bitumen modifications, like SBS. They are block copolymer Styrene-lsoprene-Styrene (SIS) and their hydrogenated derivatives SEBS and SEPS, in addition to other block copolymers that can be obtained with modification of the elastomeric phases not based on Butadiene and Isoprene mixtures, but scarcely used in practice because of high cost.
- SIS block copolymer Styrene-lsoprene-Styrene
- SEBS and SEPS hydrogenated derivatives
- block copolymers that can be obtained with modification of the elastomeric phases not based on Butadiene and Isoprene mixtures, but scarcely used in practice because of high cost.
- Thermoplastic homo, copo- or ter- polymers are used and usable for bitumen modifications. They are obtained from monomers, such as Ethylene- Vinyl Acetate (EVA), Ethylene-Propylene (EPM), Ethylene-Propylene-Diene (EPDM), Atactic and Isotactic Propylene (PPa/iso), Polyethylene (LLDPE, HDPE, LDPE ), Polybutadiene and Polybutene, but none of them, either individually or in combination, can give characteristics similar to SBS.
- EVA Ethylene- Vinyl Acetate
- EPM Ethylene-Propylene
- EPDM Ethylene-Propylene-Diene
- PPa/iso Atactic and Isotactic Propylene
- Polyethylene LLCPE, HDPE, LDPE
- Polybutadiene and Polybutene Polybutene
- BAHA "Laboratory comparison of crumb-rubber and SBS modified bitumen and hot mix asphalt” describes a comparison between crumb-rubber modified bitumen and SBS modified bitumen.
- SBS modified bitumen has much better performance than crumb rubber modified bitumen. Therefore, in order to replace SBS with crumb rubber, while maintaining the same asphalt performance, 1 :3 ratio must be applied, meaning that the quantity of crumb rubber must be at least triple than SBS. This is confirmed by the products found on the market.
- SBS modified bitumens generally have SBS quantity of 10% in weight. Instead, crumb rubber modified bitumens have a crumb rubber quantity of 30% in weight.
- US 6 818 687 discloses an SBS or SBr modified bitumen after vulcanization and grinding ; it is not said that bitumen is simultaneously SBS and SBr modified.
- bitumen has storage problems and therefore a viscosity regulator (oil) and a catalyst with acid and sulphurous base are added.
- WO2008/083451 discloses a product comprising SBS, crumb rubber and vulcanizing, plasticizing, lubricating and expanding agents.
- a thermosetting product is obtained and vulcanized. Therefore, said product is not a thermoplastic asphalt-soluble product.
- such a product is used to manufacture shoe soles and crumb rubbers is given as filler, i.e. it can be any material that needs not to have special reactions to obtain special technical characteristics.
- shoe soles are obtained via molding, not extrusion.
- the purpose of the present invention is to eliminate the drawbacks of the prior art, providing a compound that can be used to modify bitumen, is able to give the same performance as SBS with same quantity, is less expensive and at the same time has high technical characteristics and performance in order to be used in roads and building roofing compared to SBS.
- bitumen does not get vulcanized crumb rubber sufficiently wet. Considerable results are obtained for vulcanized rubber particles with granulometry lower than 0.4 mm, preferably with granulometry of 90 - 320 micron.
- modified bitumen By mixing said vulcanized rubber particles with bitumen and bringing bitumen to the melt state, modified bitumen is obtained, with characteristics very similar and comparable with bitumens modified with the use of elastomeric polymers only, such as block copolymers SBS, which are the best and most performing ones.
- the percentage in weight of the vulcanized rubber particles is 4-20 %, preferably 15% with respect to the total weight of modified bitumen.
- Recycled vulcanized crumb rubber with controlled granulometry was obtained from grinding, in some cases also cryo-grinding, with equipment provided with very effective cooling systems and suitable for screening of powders to the desired size.
- Table 1 shows the granulometry of vulcanized rubber powders obtained from grinding End-of-Use Tires (PFU) and relevant screening.
- the three samples of vulcanized rubber powders PFU 1 , PFU 2 and PFU 3 respectively have granulometry of 31 8, 172 and approximately 99 micron. Said granulometry was obtained from the weighted mean of the fractions obtained during screening.
- Table 2 shows the examples of comparative tests carried out on five samples (CO, C1 , C2, C3, C4, Cp) : a first sample (CO) composed of standard (not modified) bitumen with 1 60/220 penetration at 25 °C; three samples of modified bitumen (C1 , C2, C3) obtained by mixing standard bitumen of sample CO with three samples of vulcanized rubber powders PFU 1 , PFU 2 and PFU 3 in (85/15) weight ratio; a fifth comparison sample (Cp) obtained by mixing standard bitumen of sample (CO) with a block copolymer SBS of radial type in (85/1 5) weight ratio.
- CO first sample
- C1 , C2, C3, C4, Cp three samples of modified bitumen obtained by mixing standard bitumen of sample CO with three samples of vulcanized rubber powders PFU 1 , PFU 2 and PFU 3 in (85/15) weight ratio
- Cp fifth comparison sample obtained by mixing standard bitumen of sample (CO) with a block copo
- modified bitumen improves upon reducing the granulometry of powders.
- the Cold Flexibility test showed that the sample of modified bitumen (C1 ) starts stiffening and breaking at -15 °C; upon decreasing the granulometry of powders, the temperature at which modified bitumen will break decreases.
- samples (C1 , C2, C3) of bitumens modified with crumb rubber with low granulometry do not give satisfactory results in terms of cold flexibility or results comparable with the test sample (Cp) represented by SBS modified bitumen.
- sample C3 is not comparable with comparison sample Cp. Therefore, crump rubber itself cannot replace SBS in equal quantity.
- Table 4 shows a comparison between sample (C5) and comparison sample (Cp1 ).
- CMP extruded compound
- Sample (C6) comprises 85 bitumen parts and 20 extruded compound (CMP) parts.
- the 20 extruded compound (CMP) parts are composed of 7.5 PFU 1 parts, 7.5 radial SBS parts and 5 lubrication parts.
- Table 5 compares the comparison sample (Cp1 ) (bitumen modified with SBS and lubrication oil), sample (C5) (bitumen modified with crumb rubber, SBS and lubrication oil added separately) and sample (C6) (bitumen modified with extruded compound CMP).
- sample (C6) As shown in Table 5, the performance of sample (C6) is remarkable. The characteristics shown by sample (C6) are by far better than sample (C5) and comparable or even better than the comparison sample (Cp1 ). Consequently, sample (C6) made it possible to achieve the purpose of the present invention, viz. to replace SBS used to modify bitumens with an inexpensive product with the same performance as SBS with the same quantity.
- sample C5 active elements PFU 1 and SBS
- sample C6 active elements PFU 1 and SBS
- PFU 1 and SBS the same active elements
- the physical characteristics of sample C6 are definitely better than C5: cold flexibility is lower by 4 °C, Ring-ball is higher by 19 °C and Penetration is lower by 17°C; this is what is normally desired in bitumen modification.
- PFU behaves as an inert filler, but being provided with good intrinsic elasticity, gives certain resilient characteristic to bitumen, which is certainly not comparable with SBS with the same replacement quantities. Moreover, PFU granules are surrounded by bituminous components, which have different solubility parameters, not comparable with PFU. For this reason, no sufficient cohesive forces are developed and consequently phase interruptions are generated.
- TPV Thermoplastic Polymers dynamically Vulcanized
- EPDM has a solubility parameter close to Polypropylene, therefore the vulcanized EPDM solid particle gets wet and is connected to PP, which is a rigid product, and from this combination an elastomer suitable for the most diverse and interesting uses is obtained.
- the PFU and SBS compound will combine in fusion with bitumen, but after cooling its three-dimensional network formed of SBS and solid PFU will incorporate the bituminous phase while maintaining its elastic structure with the physical characteristics disclosed in the present invention.
- this phenomenon is known as IPN (Interpenetrating Polymer Network) and, when connected to the phenomenon described in the TPV process, contributes to explain the difference in performance between sample C5 and sample C6 according to the invention.
- the production process of the compound according to the invention comprises the following steps:
- - granulometry of vulcanized crumb rubber is between 0.09 and 0.32 mm ;
- - SBS weight percentage is equal to weight percentage of vulcanized crumb rubber
- - SBS is preferably of radial type, but can also be linear or a mixture of radial SBS and linear SBS;
- - lubricant is in weight percentage between 20-30% with respect to total weight of compound
- - lubricant is a mineral oil
- the compound obtained from the extruder is cut in chips of any size. Said chips of extruded compound are used to modify bitumens. Bitumen is modified by adding a weight percentage of extruded compound between 5% and 30% with respect to total weight of modified bitumen. Said bitumen modified with extruded compound has a performance similar to SBS modified bitumens, with the same quantity of SBS and extruded compound, but the cost of extruded compound is considerably lower than SBS.
