Abstract
The effect of Crosslink density on Cut and Chip resistance was affected on a typical 100 percent styrene-butadiene rubber (SBR)-based tire tread compound. In order to successfully develop products for tires used in off-road or poor roads and other demanding rubber applications, it is important to understand the C and C effect in rubber. Crosslink density varied by varying the sulphur to the accelerator ratio and also by changing the process aids. Basic polymer, filler and other ingredients such as activators and anti-degradants have remained unchanged. In the first setup, the sulphur was kept constant and the accelerator varied and the reverse was done in the second setup. It was made to achieve different crosslink density by changing the oil dosage and adding different resins. An attempt has been made to correlate Cut and Chip resistance to other physical properties. All these tests have been identified and optimized by the traditional tire tread compound.
Highlights
The use of giant tires in off-the road systems (OTR), such as tractor, grader, backhoe, front end loader, etc., is routinely to be heavily cut and chipped when used in areas not accessible by traditional concrete or asphalt paths
The aim of this work is to study the effect of crosslink density on cut and chip resistance of 100% sbr based tire tread compounds on typical tire tread compounds
3.1 Physical Properties In an attempt to explain the observed results on the cut and chip resistance, some physical properties were measured for the 100% styrene-butadiene rubber (SBR) based tire tread compounds
Summary
The use of giant tires in off-the road systems (OTR), such as tractor, grader, backhoe, front end loader, etc., is routinely to be heavily cut and chipped when used in areas not accessible by traditional concrete or asphalt paths. Cutting happens when a sharp object hits a surface with sufficient force to penetrate and cut the surface [1]. The chipping of the rubber compound is generally tearing at 90° to the cutting direction, due to the effect of the traction, braking and other forces on raw or sharp surfaces. Cutting and Chipping causes the tire tread to tearing away the big chips. Without tearing; chipping is relatively sudden, and with tear force. Neither cutting nor chipping has to do with the propagation of crack or propagation of fatigue [2]
