Description

Technical field [0001] The invention belongs to the technical field of rubber material preparation, and specifically relates to a modified rubber material. Background technique [0002] Rubber: a highly elastic polymer material with reversible deformation. It is elastic at room temperature, can produce large deformation under a small external force, and can return to its original state after removing the external force. Rubber is a completely amorphous polymer, its glass transition temperature (Tg) is low, and the molecular weight is often large, more than several hundred thousand. [0003] The word rubber comes from the Indian word cau-uchu, which means "tree with tears." Natural rubber is made by coagulating and drying the latex that flows out when the rubber tree is tapped. In 1770, the British chemist J. Priestley discovered that rubber can be used to erase pencil writing. At that time, the material for this purpose was called rubber, and this term is still used today. The ...
