[0006] At present, there have been patents to apply rubber products to pulp transportation pipelines. For example, Chinese patent 2014106610561 discloses a mineral dressing that is soft (low hardness), good in elasticity, well bonded to the metal shell, flat on the surface of the rubber sheet, and good in corrosion resistance. Use the rubber lining material and preparation process of high wear-resistant and anti-corrosionslurry conveying pipeline, blend epoxidized natural rubber with natural rubber, and improve the medium resistance, barrier performance, Adhesion to metals and composite properties with active fillers; adding nano-siliconnitride to the epoxidized natural rubber / natural rubber blend system makes nano-Si 3 N 4 The amino group on the surface of the powder reacts with the epoxy group in the molecular structure of epoxidized natural rubber to give full play to the filling modification effect of nano-siliconnitride such as wear resistance and medium resistance, but the anti-corrosion effect of the invention is not significant

technical field [0001] The invention relates to the rubber field, in particular to a rubber material used for a liquid filter and a preparation method thereof. Background technique [0002] Rubber products are widely used in all aspects of industry or life. Rubber refers to 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 shape after the external force is removed. Rubber is a completely amorphous polymer with a low glass transition temperature and often a large molecular weight, greater than hundreds of thousands. [0003] The early rubber was latex taken from plants such as rubber trees and rubber grasses. After processing, it was made into elastic, insulating, impervious to water and air, and high-elastic polymer compounds. Rubber is divided into two kinds of natural rubber and synthetic rubber. Natural rubber is processed by extrac...
