Abstract

The invention discloses a fatigue resistant rubber additive and relates to the technical field of rubber materials. The fatigue resistant rubber additive is obtained with a mixture of polycyclic aminemodified nano-crystalline cellulose and graphene, wherein the nano-crystalline cellulose and the graphene are mixed according to the mass ratio of 10 to (1.3-1.5). The fatigue resistant rubber additive provided by the invention is applied to the rubber materials to be capable of remarkably improving the fatigue resistance of the rubber materials.

Description

technical field [0001] The invention belongs to the technical field of rubber materials, and in particular relates to a fatigue-resistant rubber additive. Background technique [0002] Rubber is a high-molecular material with excellent stretching and elasticity. It is widely used in the manufacture of automobile tires, waterproof sheets, tapes, hoses, seals, etc. It has a history of nearly a hundred years. The growth process of local structural changes and internal defects is called rubber fatigue. Under dynamic tension, compression, twisting and shearing, the performance and structure of rubber products will change or be destroyed, which is the so-called fatigue damage. It reduces the mechanical properties of the material and eventually leads to cracking or complete fracture. The essence of rubber fatigue is the appearance of rubber aging under the action of force and heat, including flex fatigue and aging fatigue. There are many conditions for rubber to fatigue, for exa...
