Rubber shock absorbing pad for motor is a rubber product installed among the motor and the support structure to protect the motor and the surrounding environment from vibration, and its main role is shock absorption, sound insulation and protection. Butyl rubber with good shock absorption, chemical corrosion resistance and temperature resistance is one of the ideal materials for the production of motor shock absorbing rubber pads. Butyl reclaimed rubber is processed from waste butyl inner tube as the main raw material, which can be used alone or combined with butyl rubber to produce shock-absorbing rubber pads for motors, effectively reducing the cost of rubber raw materials.
Butyl reclaimed rubber has good air tightness, shock absorption, ozone resistance, aging resistance, etc., which can meet the performance requirements of shock-absorbing rubber pads for motors. When butyl reclaimed rubber is used in the production of shock-absorbing rubber pads for motors, the specific mixing ratio is determined according to the specific technical parameter requirements of the shock-absorbing pads and the physical properties of butyl reclaimed rubber. Butyl reclaimed rubber can also be used in combination with an appropriate amount of butyl rubber or EPDM rubber to improve the comprehensive performance of shock absorbing pads; In particular, the use of an appropriate amount of EPDM rubber can reduce the dependence of the shock-absorbing characteristics of butyl reclaimed rubber pads on temperature and vibration frequency.
Factors such as the design of the vulcanization system, the selection of reinforcing agents and fillers, and the amount of plasticizer in the vulcanization formula of rubber shock absorbing pads for motors in the production of butyl reclaimed rubber will affect the shock absorption effect of the final product.
When using butyl reclaimed rubber as the main raw material to produce rubber pads for motors, the design of vulcanization system has a significant impact on the stiffness, damping coefficient, heat resistance and fatigue resistance of shock absorbing rubber pads. When using sulfur vulcanized butyl reclaimed rubber, accelerators CZ, NOBS, D, DM, M, etc. can be used together; The vulcanization system should be designed to ensure that the rubber can be sufficiently vulcanized to form a stable cross-linking network, e.g. the combination of thiuram accelerators and thiazole accelerators can provide good vulcanization properties while avoiding excessive vulcanization, which may cause the rubber to harden and reduce its elastic and damping properties.
The butyl reclaimed rubber reinforcing filling system generally uses carbon black reinforcement to improve the strength and wear resistance of the rubber, but excessive amount may cause the vulcanized rubber to harden and reduce its elasticity and damping properties. Different types of carbon black have different structural and surface properties, and the particle size and blending amount of carbon black used will affect the durability and dynamic rate of the product. The use of calcium carbonate filling can reduce costs, but the amount used needs to be controlled, and excessive dosage may affect the hardness and stiffness of the rubber.
When using butyl reclaimed rubber to produce shock-absorbing rubber pads for motors, the design of the softening system, the coordination of the anti-aging system and the production process will affect the physical properties of the rubber shock-absorbing pads, especially the mixing process and vulcanization process, and we will continue to discuss related issues with you in the future.
