Rheological properties of ground tyre rubber based thermoplastic elastomeric blends

Abstract

h i g h l i g h t sA physical air-entraining method has been reported. The properties of high porosity cement-based foam materials have been investigated. Influence of water-cement ratio and HPMC on material properties has been analyzed. Pore structure formation mechanism has been clarified. a b s t r a c tHigh porosity cement-based foam materials were prepared through physical air-entraining method and the pore structure and the properties of materials were characterized. The results show that water-cement ratio and Hydroxypropyl Methyl Cellulose (HPMC) content have crucial influence on material properties. When the water-cement ratio was 0.9 and the content of HPMC was 0.4%, the cement-based foam material with the porosity of 94.33% and thermal conductivity value of 0.049 W/(m K) could be obtained. The formation mechanism of pore structure was analyzed that water-cement ratio and HPMC content affect the bubble film toughness which influence on material properties.

Structure and properties of styrene-butadiene rubber (SBR) with pyrolytic and industrial carbon black

“…However, the traditional application field of GTR (covers of sporting fields and play grounds) is saturated, therefore, considerable efforts are made to convert GTR into other value added products. Reclaimed GTR, by whatever means achieved, may be used in fresh rubber mixes [1,2]. The production of thermoplastic rubbers with the use of GTR is strongly preferred, though this requires some "activation" (e.g.…”

Rheological characterization of polyethylene/polyester recycled tire fibers/ground tire rubber composites

“…Figure shows the complex viscosity (η*) of the composites as a function of angular frequency for different RTF content [Figure (a)], mixing speed [Figure (b)], and temperature profiles [Figure (c)]. It is obvious that the presence of rubber particles embedded in the RTF increased the complex viscosity due to the crosslinked structure of GTR and the effect increases with increasing RTF content [Figure (a)]. Moreover, it is known that for a fixed GTR content, finer rubber particles impart higher viscosities due to higher surface contact area .…”

Aplicaciones de caucho reciclado: Una revisión de la literatura

“…Lima et al [77] demostraron que la incorporación de CTR en matrices termoplásticas es una alternativa viable para darle una aplicación de valor agregado a los residuos de este tipo. Los autores evaluaron experimen-presas, bien sea de países desarrollados o de aquellos en vía de desarrollo.…”
