Problems solved by technology

[0010] The invention aims to overcome the deficiencies in the prior art that rubber products are stuck under force during transportation and storage, and its slipperiness cannot meet the needs of online transportation and assembly in an automated production line, and provides a self-lubricating material for filter seals and Its preparation method, the fluorine wax FU-305 in the vulcanized rubber material of the present invention migrates to the surface of the product, so that a layer of uniform, transparent, bright, and strong adhesion film is formed on the surface of the tablet, reducing the surface of the rubber seal. The coefficient of friction effectively prevents the adhesion between the rubber parts and the metal body, and meets the requirements for the filter to be assembled on the automatic production line. Improved ozone aging resistance

Abstract

The invention discloses a self-lubricating material for a filter sealing piece and a preparation method thereof, belonging to the fields of sealing rubber materials and preparation methods thereof. The self-lubricating material consists of the following components in percentage by weight: 40-45 percent of nitrile rubber, 20-25 percent of high-wear-resistance carbon black, 10-15 percent of semi-reinforced carbon black, 3.0-5.0 percent of zinc oxide, 0.5-1.0 percent of stearic acid, 1.0-1.5 percent of 4,4'-di(phenyl isopropyl)diphenylamine, 0.5-1.0 percent of 1,3-dihydro-4(or 5)-methyl-2H-benzimidazole-2-thione zinc salt, 0.1-0.3 percent of sulfur, 1.0-2.0 percent of accelerant DTDM (Dithiodimorpholine), 0.5-1.0 percent of accelerant CZ, 3.0-6.0 percent of hexanedioic acid di[2-(2-butoxy oxethyl)ethyl ester] and 1.0-1.5 percent of fluorine wax FU-305. The method comprises the following preparation steps of: compounding a master batch; performing two-stage vulcanization on the master batch; and vulcanizing. A layer of uniform, transparent and bright film with high adhesion is formed when the fluorine wax FU-305 is transferred onto the surface of a rubber product, so that the friction coefficient of the surface of the rubber sealing piece is reduced, bonding between the rubber piece and a metal body is prevented effectively, and the ozone aging resistance is enhanced effectively.
