Investigate on mechanical and tribological properties of solution styrene butadiene and butadiene rubber composites

Abstract

Solution styrene butadiene and butadiene rubber (SSBR-BR) composites reinforced with different contents of SiO 2 -graphene have been fabricated firstly. The mechanical properties of the rubber composites were comparatively investigated using tensile tests; experimental results showed that, as an overall trend, the tensile and tear strength increased with increasing contents of SiO 2 -graphene. Most importantly, under the condition of simulating practical working condition, the tribological behavior of SSBR-BR composites with different contents of SiO 2 -graphene was explored via a universal ring-plate frictional tester in detail. Combined with the surface roughness of the counterparts, the wear mechanisms were discussed for SSBR-BR composites under the cement and asphalt counterparts. Finally, several wear mechanisms under different actual working conditions were proposed.

Toward Mechanically Robust Crosslinked Elastomers through Phase Transfer Agent Tuning the Solubility of Zn2+ in the Organic Phase

“…To highlight the importance of phase transfer agent to properties of crosslinked elastomers, we compare tensile strength, tear strength, and elongation at break among this work and the elastomers with different accelerators in Figure 4 c,d. The data of elastomers with different accelerators are from the previous works, containing N-cyclohexyl-2-benzothiazolesulfenamide (CZ) [ 28 , 29 , 30 , 31 , 32 , 33 , 34 , 35 , 36 , 37 , 38 , 39 , 40 , 41 , 42 , 43 , 44 , 45 , 46 , 47 , 48 ], diphenyl guanidine (D) [ 49 , 50 ], dibenzothiazyl disulfide (DM) [ 51 , 52 , 53 , 54 , 55 , 56 , 57 ], 2-mercaptobenzothiazole (M) [ 2 , 58 , 59 , 60 , 61 , 62 , 63 , 64 , 65 ], N-tert-butylbenzothiazole-2-sulphenamide (NS) [ 30 , 66 , 67 , 68 , 69 , 70 , 71 ], and tetra methyl thiuram disulfide (TMTD) [ 30...…”

A novel methodology for evaluating wear behavior of rubber composites under combination of sliding and rolling conditions

“…Actually, the evaluation of tire wear resistance on the road is costly and consumes high energy and time, accurate evaluation of tire tread rubber on a laboratory scale is therefore always of interest and of extremely important for material developments and engineering applications. In our previous studies, [8,19,20] to access to the practical working condition, the improved MM-200 and Taber frictional tester have been chosen to investigate the friction and wear mechanism of tire tread rubber composites, respectively. More remarkable, both of them are typical sliding wear conditions.…”

“…Likewise, Taber abrasion is also commonly applied to test the wear resistance of rubber materials. [19,20] Despite of development of various laboratory test setups and numerous simulation methods in the literature, an accurate evaluation of wear behavior of tread rubber composites in the laboratory is a big challenge.…”
