In this context, this work discussed the partial replacement of waste tire rubber (WR) and microwave devulcanized rubber (DWR) at different ratios on the properties of virgin styrene butadiene rubber (SBR) as one of the most essential components of synthetic rubber in the tire production. Fixed percent of tetramethylthiuram disulfide and spindle oil were added at the first, then the WR mixture was exposed to different microwave times. Microwave devulcanization value at time 6 min gave the highest devulcanization percent. The prepared blends were exposed in an electron beam accelerator (EB) at 50 and 100 kGy. FTIR, different mechanical parameters, thermal stability (TGA) and scanning electron microscopy of the fabricated specimens have been explained. Effect of automotive oil and thermal aging at different temperature, 70oC and 100oC on the tensile strength and elongation at break (E%) of the unirradiated and irradiated prepared blends have been estimated. Mechanical measurements of all examined specimens after thermal aging and oil immersion were least affected. Moreover, these factors before and after oil dipping and thermal aging revealed that unirradiated and irradiated SBR/DWR blends have superior properties than SBR/WR.

The rubber powder used was obtained as waste in the technological processes in the rubber industry. It was analyzed by determining the acetonic extract, ash and FTIR analysis and it was observed that the base elastomer in the rubber waste is silicone rubber, and the amounts of inorganic fillers, plasticizers, antioxidants, lubricants etc. existing in the rubber powder are lower than 19%. The samples were obtained by mixing technique, on Brabender Plasti-Corder internal mixer type. The test specimens necessary to determine the characteristics were obtained on a laboratory electrical press at 170°C, applying a force of 300 kN, and moulding time 6 min. The characteristics of the obtained samples show that the addition of rubber powder improved the hardness and elasticity, and by the applying compatibility method, namely crosslinking and grafting in melt, in dynamic regime, there was a significant increase in hardness, elasticity, modulus 100%, tensile strength, and the material obtained is more compact. The new composites have physical and mechanical properties suitable for producing a wide range of rubber consumer goods.","PeriodicalId":20860,"journal":{"name":"Progress in Rubber Plastics and Recycling Technology","volume":null,"pages":null},"PeriodicalIF":2.6,"publicationDate":"2022-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83960135","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The optimized condition of PET hydrolysis was 100°C with 80% v/v aqueous sulfuric acid liquor for 30 min reaction time. The terephthalic acids (TPAs) were filtered out from the reaction mixtures with a sintered glass filter. The viscosity of recycled hydrolysis liquor was measured before it was used in a successive batch of PET depolymerization. The viscosity of hydrolysis liquor increased gradually from 5 mm2/s to 87 mm2/s. TPA yields were obtained from 85.03 ± 0.03% to 99.20 ± 0.06% and the color of TPA changed from bright white to off-white in the final batches. The structure of TPA was confirmed by FTIR, mass analysis, and 1H-NMR spectroscopy. The purity of TPA was found to be 95–98% from the HPLC study via external calibration technique. Thermogravimetric analysis (TGA) determined the thermal degradation patterns of TPAs and residual weights. This experiment reveals that repeated use of sulfuric acid hydrolysis liquor would be a good option for PET depolymerization in terms of resource utilization, TPA quality as well as sustainability.

In an aqueous system, microplastic does not always present as a single particle, and these microparticles tend to aggregate and subsequently causing severe ecological risks. The exploration of the underlying mechanisms on how microplastics aggregate in seawater and freshwater enables the prediction of their diffusivity, distribution, and bioavailability in the water environment. In this study microplastic model systems of polypropylene (PP) and poly(vinyl chloride) (PVC) were used to investigate the interactions and aggregation size between microplastics in seawater and with the response anionic sodium dioctyl sulfosuccinate (AOT) surfactant dosages via electrophoretic mobility and Dynamic Light Scattering (DLS) measurements, supported by the UV-Vis spectrum analysis. This investigation revealed that mobile ions present in water ecosystems played a vital role in the surface interactions between microplastics and their aggregation behaviour. The surface charge of both PP and PVC microplastics were switched to a positive value at 5 wt.% of AOT and continued in the negative regime with increasing AOT concentration. Upon the addition of surfactant, surface charge neutralization and aggregation of PP and PVC microplastics were detected; however, the restabilization of microplastic was observed with increasing concentration of surfactant.","PeriodicalId":20860,"journal":{"name":"Progress in Rubber Plastics and Recycling Technology","volume":null,"pages":null},"PeriodicalIF":2.6,"publicationDate":"2022-09-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75923712","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Presents results indicate that the carbon black embedded in the GTR interior phase of the GTR/NR re-vulcanized blends, did not participate in the NR phase molecular motion restriction. The blends of GTR/NR showed the phenomenon known as reversion, leading a decreasing of the mechanical properties, that could be attributed of the degradation of the interphases (GTR/NR) n+j, j=1,2,3,…. On the other hand, the Cole-Cole charts of the GTR/NR vulcanized blends changed from a semicircular to an irregular form as the NR concentration increases, imposing the heterogeneity of the blend. In addition, in the Cole-Cole charts of GTR/NR vulcanized and re-vulcanized blends, the height ( E´´ ) and the width ( E´ ) of the curves decreased while the re-vulcanization processes number was greater; obtained results could be attributed to the increasing of the molecular cross-linking density.","PeriodicalId":20860,"journal":{"name":"Progress in Rubber Plastics and Recycling Technology","volume":null,"pages":null},"PeriodicalIF":2.6,"publicationDate":"2022-09-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89644415","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
