چکیده
The management of end-of-life tires (ELTs) is one the main environmental issues that society faces nowadays. Recycling ELTs appears as feasible option for tackling problem, although their incorporation ground tire rubber (GTR) in other matrices limited due to poor compatibility. In this research, we report a successful combination cryo-grinding process with chemical treatment modifying surface GTR. Various protocols were studied until particle size 100–150 µm was achieved. Chemical treatments different acids also analyzed, resulting optimal modification sulfuric acid (H2SO4). Modified GTR added styrene-butadiene (SBR) matrix. 10 phr filler resulted composite improved mechanical performance, increments 115% and 761% tensile strength elongation at break, respectively. These results validate use recycled material from waste sustainable composites.

Thermal Stability and Flammability of Styrene-Butadiene Rubber-Based (SBR) Ceramifiable Composites
Ceramifiable styrene-butadiene (SBR)-based composites containing low-softening-point-temperature glassy frit promoting ceramification, precipitated silica, one of four thermally stable refractory fillers (halloysite, calcined kaolin, mica or wollastonite) and a sulfur-based curing system were prepared. Kinetics of vulcanization and basic mechanical properties were analyzed and added as Suppleme...
متن کاملThe Effect of Styrene-Butadiene-Rubber (SBR) Polymer Modifier on Properties of Bitumen
Abstract—In order to use bitumen in hot mix asphalt, it must have specific characteristics. There are some methods to reach these properties. Using polymer modifiers are one of the methods to modify the bitumen properties. In this paper the effect of StyreneButadiene-Rubber that is one of the bitumen polymer modifiers on rheology properties of bitumen is studied. In this regard, the rheological...
متن کاملEnvironmental epidemiologic investigations in the styrene-butadiene rubber production industry.
A review of the literature and an update that is in progress of a previous retrospective cohort mortality study of the styrene-1,3-butadiene industry are discussed. The follow-up has now been extended from April 1, 1976, through December 31, 1981, for plant B and December 31, 1982, for plant A. The person-years at risk of death have gone from 34,187 to 43,341 in plant A and from 19,742 to 26,31...
متن کاملHazardous organic chemicals in rubber recycled tire playgrounds and pavers.
In this study, the presence of hazardous organic chemicals in surfaces containing recycled rubber tires is investigated. Direct material analyses using solvent extraction, as well as SPME analysis of the vapour phase above the sample, were carried out. Twenty-one rubber mulch samples were collected from nine different playgrounds. In addition, seven commercial samples of recycled rubber pavers ...
