Description

technical field [0001] The invention relates to the field of rubber seals, in particular to a wear-resistant, heat-resistant, acid and alkali-resistant modified rubber seal. Background technique [0002] Rubber seals are a general basic component in sealing devices Rubber seals are a type of rubber products widely used in sealing technology. Because of its very small elastic modulus, high elongation, and air resistance, it is widely used for installation on various mechanical equipment. Because the lubricating system of mechanical equipment contains acid and alkali components, it is easy to penetrate into the seal, thereby causing the expansion of the seal and affecting the service life of the seal; in addition, the seal has high requirements on wear resistance during use. . [0003] The wear-resistant, heat-resistant and acid-alkali-resistant properties of the rubber seals in the prior art cannot meet the needs of actual use, so it is urgent to design a wear-resistant, he...
