In this study, two identical groups based on carbon black (CB) filled styrene butadiene rubber (SBR) vulcanisates were prepared by incorporating different proportions (10–50 phr) of treated and untreated rice straw (TRS/ URS) in the SBR composites to examine their effects on some of the demanded properties in rubber applications. Maleic anhydride (MA), as a coupling agent, was added to improve the interfacial bonding between the hydrophilic RS natural fibre and the hydrophobic SBR matrix. The TRS and URS were selectively grinded through a grinding machine to obtain RS fine powder with a selective grain size distribution ranging from about 20–180 μm. Some important physico-mechanical properties of the rubber vulcanisates were studied. The prepared samples were analysed by using X- ray diffractometer (XRD) and scanning electron microscopy (SEM). The tensile strength (TS), modulus (M100) and hardness values of TRS filled composites were almost superior compared to the URS ones, and 20 phr of TRS was found to be the optimum filling in SBR vulcanisates and this was obviously revealed through all the mechanical properties results as well as in the percentage swelling findings. The SEM analysis indicates that the presence of MA increases the interfacial interaction between SBR, and the alkali treated rice straw fibres, as well it was found to be in complete agreement with the TS findings. The XRD analysis reveals that the alkaline pretreatment of RS fibres was found to yield a higher crystallinity index for the SBR vulcanisates. The results indicate the potential of using TRS as filler in the rubber industry for cost reduction and raising the environmental credentials of the product.</p></div>","PeriodicalId":662,"journal":{"name":"Journal of Rubber Research","volume":"27 4","pages":"639 - 652"},"PeriodicalIF":1.2,"publicationDate":"2024-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142645649","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The highest observed hysteresis loss ratio was 0.32 in DPNR latex foam loaded with 24 phr of OPTB. Additionally, OPTB loading up to 24 phr in DPNR latex foam decreased its rebound resilience from 66 to 55% and increased its vibration-damping ratio from 0.14 to 0.24.

Seven samples are prepared and tested for their mechanical properties using which the optimum combination is determined by adopting Grey Relation Analysis (GRA)-based Response Surface Methodology (RSM) approach and benchmarked using GRA based Kriging-GA surrogate optimisation. The confirmed optimum combination of ECH blend is 33.34/53.33/13.33 phr. Hence in the second part, this optimum blend is taken as the base matrix for developing novel hybrid filled ECH composites by varying the filler contents of CB and silica. Thirteen composites are fabricated following a Face Centered Central Composite (CCF) design and tested for mechanical properties. The optimisation of hybrid filler content is carried out following the same numerical techniques used for optimum blend determination.

In this work, we selected one bio-based vegetable oil (FN-B17) as green processing aid for nature rubber (NR) composites and petroleum-based oils (PB-1,2,3,4,5) were also chosen to be investigated for comparison. The plasticisation effects of FN-B17 and other plasticisers on composites were systematically studied. In specific, Mooney viscosity, processing properties and cross-linking characteristics of composites with various kinds of oils were characterised while the mechanical properties and RPA dynamic behaviors were also evaluated. The results indicated that the performance of bio-based oil on processing and mechanical properties of NR composites are similar or even better than that of petroleum-based oils, whereas bio-based oil is renewable with lower cost, which would be cost-effective green processing oil that could replace petroleum-based oil for NR composites.
