Rubber is an extremely important class of major binders in the composition system of friction materials. Looking back to the early days, pure resin friction pads dominated the market. The nature of the resin used at that time was characterized by brittleness and hardness, which directly led to the overall brittleness and hardness of the friction pads, which showed very poor resistance in the face of impact. In the braking process, once suffered a large impact, pure resin friction pads are very easy to rupture, slagging and other conditions, seriously affecting its service life and braking performance.
After researchers and front-line workers continue to carry out a large number of tests, and combined with a wealth of practical experience, gradually found that rubber materials can significantly improve this unfavorable situation. Rubber has good flexibility and elasticity, after its introduction into the friction material, can effectively relieve the brittleness of the material. When mixed with resins, the two can complement each other. Nowadays, most of the friction pads on the market are formulated with a mixture of resin and rubber. By precisely mixing the ratio of the two, their respective shortcomings can be fully neutralized, thus producing a friction material with better overall performance.
In the field of resin-based binder friction materials, it occupies the absolute advantage in terms of quantity and variety. This type of friction disk is stiff and has a range of outstanding performance. It maintains a high coefficient of friction at low temperatures, ensuring that the braking system responds quickly and provides reliable braking power even in cold weather. Even at high temperatures, the coefficient of friction remains stable and has a long service life. This enables it to operate under severe conditions of high braking pressure and friction speed, and it is widely used in applications such as high-speed automobiles, heavy-duty trucks, and industrial braking equipment, where braking performance is of the utmost importance.
In contrast, friction materials with rubber as the main binder are softer. This characteristic determines that it is mainly suitable for braking pressure and relative friction speed is low, and the working temperature is not high working environment. For example, in some small electric cars, home elevators and some of the braking precision requirements for high but not much braking energy demand equipment, rubber-based friction material can rely on its soft texture, to achieve smooth and quiet braking effect, reduce the wear and tear on the equipment components, to extend the overall service life of the equipment.
In summary, both resin-based binders and rubber-based binders have their own unique value in the field of friction materials. Their advantages and disadvantages are distinctive, and can precisely match different application scenarios and working conditions. In the actual selection and application, need to fully consider the operating conditions of the equipment, performance requirements and other factors, so as to select the most appropriate bonding friction materials to ensure the safe and efficient operation of the equipment.
