Improvement of filler-rubber interaction by the coupling action of vegetable oil in carbon black reinforced rubber

Abstract

Vegetable oil has been added in small amount to the rubber compound during mixing. It has been observed that the extent of cure obtained from the rheometric torque is lower for vegetable oil-containing compounds. This has been manifested from their physical and tensile properties. The lower abrasion and hardness of vegetable oil-containing compounds may be due to better plasticization and lower crosslink density. The lower tan Ѩ at maximum torque indicates lower loss and heat generation. The vegetable oil-containing compounds shows lower modulus, higher tensile strength, and elongation. All the compounds containing vegetable oil shows lower compression set and higher rebound resilience, tear strength, and flex cracking compared to the standard compound containing no vegetable oil.

Fatty acid benzyl esters asbio‐basedplasticizers insilica‐filled solution‐polymerized styrene‐butadienerubber/butadiene rubber composites

“…Nowadays, various vegetable oils and their derivatives, [ 18‐24 ] which are nontoxic, cost effective and renewable, have been studied as plasticizers. They all show desired performance in the rubber compounds.…”

Effect of vinyl and phenyl group content on the physical and dynamic mechanical properties of HVBR and SSBR

“…[10][11][12] In previous studies, the physical and dynamic mechanical properties of SSBR modified by rubber blending or rubber fillers have been macroscopically explored, but the reasons for the apparent differences in these properties have rarely been analyzed in terms of the microscopic molecular chain structure. [24][25][26][27][28][29] However, the interaction between CB and rubber matrix has an effect on the properties of the rubber matrix, so we also investigated and compared the effect of vinyl and phenyl groups on the physical and dynamic mechanical properties of the vulcanizates with or without CB. Therefore, in this study, great importance was attached to establishing the relationship between the contents of vinyl and phenyl groups and the properties of vulcanizates for the first time, which could be beneficial to establishing a theoretical model on the basis of some experimental data, thereby providing instructional significance for the structural design of synthetic rubber.…”

“…[19][20][21][22][23] Carbon black (CB) as a rubber filler can be strongly adsorbed by nonpolar and low-polarity polymers to partially fix the rubber molecular chains to further improve the mechanical strength of the rubber matrix. [24][25][26][27][28][29] However, the interaction between CB and rubber matrix has an effect on the properties of the rubber matrix, so we also investigated and compared the effect of vinyl and phenyl groups on the physical and dynamic mechanical properties of the vulcanizates with or without CB. Therefore, in this study, the effects of vinyl and phenyl groups and their contents on the mechanical properties and dynamic viscoelasticities of HVBR and SSBR with or without CB were highlighted for the first time, and a theoretical approach to developing high-performance rubber materials was put forward.…”

Optimization of PET Glycolysis Process by Response Surface Methodological Approach: A Two-Component Modelling Using Glycolysis Time and Temperature

“…The technique requires minimum experimentation and time, thus proving to be far more friendly and cost-effective than the conventional methods. RSM in rubber compounding was successfully used by Kundu [14] with good accuracy. If Y is the response of a process dependent on the levels of k factors (x 1 , x 2 , .…”
