Description

technical field [0001] The invention belongs to the field of performance detection of polymer materials, and relates to the detection of the friction performance of a rubber-based polymer material, in particular, a friction testing machine and an experimental method. Background technique [0002] Nowadays, since rubber is a high-molecular polymer material with high elasticity and reversible deformation, compared with most other solid materials, rubber has special friction characteristics. In addition, rubber contains non-negligible internal friction, a property that makes the relationship between the real contact area of ​​rubber and its contact pressure load non-linear. Therefore, research on the detection of rubber friction properties under different external environmental conditions is of great significance for the production and processing of rubber and the application of rubber in real life. There are many factors that affect the friction of rubber, especially the slid...
