Problems solved by technology

[0003] Natural rubber is a kind of tensile crystalline rubber. Its crystallinity makes inorganic fillers and vulcanizates containing inert fillers have higher strength when stretched. Through graft modification, the comprehensive properties of rubber can be improved, and good comprehensive properties can be obtained. Advanced rubber materials, so that it can be used in shock-absorbing materials to solve the problems of poor impact resistance and fatigue of existing rubber materials

Description

technical field [0001] The invention relates to the technical field of rubber, in particular to a shock-absorbing rubber composition. Background technique [0002] Shock and vibration are common phenomena in industry. Since not all vibration-sensitive machinery and equipment have shock absorption and shock resistance, shock absorption is an important part of the design and installation of mechanical equipment. Adding shock absorbing elements between mechanical equipment and the foundation (or floor, floor) to reduce the impact of the source on the foundation and equipment is the earliest and most commonly used shock absorbing method. Industrial "three machines and one pump" (fans, air compressors, refrigerators, water pumps), vibrating screens, machine tools, internal combustion engines, vacuum pumps, metal forging presses, injection molding machines and other electric drive and reciprocating mechanical equipment, automobiles Engine mounts, suspension components, rubber sp...
