Short fibre radial orientation tread rubber abrasion continuous testing method

Abstract

The invention belongs to the technical field of rubber abrasion detection, and relates to a short fibre radial orientation tread rubber abrasion continuous testing method. The short fibre radial orientation tread rubber abrasion continuous testing method comprises specifically manufacturing and fixing of a sample, loading of a grinding mechanism, rotating of a grinding wheel, deflecting of the grinding wheel, weighing of sample particles and result comparing; the adjustment of different loads is realized by the loading control of the grinding mechanism, the adjustment of different rotation speeds is realized by controlling the rotating of the grinding wheel, and the adjustment of different abrasion angles is realized by the controlling of the deflection of the grinding wheel; when a new test is performed, the next experiment is performed by taking the sample on the rubber wheel and bonding the new sample without stopping a machine, so as to realize the continuous test; by the method, the technology gap in the short fibre radial tread rubber abrasion test in the prior art is filled, the wearing resistance of the short fibre radial orientation tread rubber under different conditions is indicated truly and effectively; the testing efficiency is high, and the method is applicable for industrial production.

Description

Technical field: [0001] The invention belongs to the technical field of rubber wear detection, and relates to a rubber wear test method, in particular to a continuous test method for short fiber radially oriented tread rubber abrasion, which is used to test short fiber radially oriented tread rubber under different environmental conditions. under wear performance. Background technique: [0002] So far, the common test methods for rubber wear in the laboratory include Akron abrasion, DIN abrasion and Grassier abrasion and other experimental methods. , with a certain inclination angle to carry out rolling friction with the alumina grinding wheel; this method is mainly suitable for rubber materials with a Shore hardness of 55-80. Although the device involved is simple in structure and widely used, it is troublesome to prepare the sample and relatively slippery The ratio is different for different rubbers, resulting in a certain impact on the wear results; the DIN wear test met...
