Embodiment 1

[0014] A sealing ring for filter bottom shell and upper cover, which is composed of the following raw materials in parts by weight: neoprene CR121 55, hydrogenated nitrile rubber ZP2020 (Japan Zion) 50, zinc stearate 2 , Coumarone 8, 2-mercaptobenzimidazole 1, chlorinated paraffin 4, semi-reinforcing carbon black SRF 110, montmorillonite powder 20, adipate 2, accelerator PZ 1, accelerator TETD 1, Cross-linking agent TAC 1.8, anti-aging agent RD 0.8, antioxidant 1010 2, modified diatomaceous earth 1.

[0015] The preparation method of the sealing ring used for the filter bottom case and the upper cover includes the following steps:

[0016] (1) Prepare raw materials according to the raw material components of each weight part, put each raw material into an internal mixer, synthesize rubber through the internal mixer, and filter;

[0017] (2) Detect the filtered synthetic rubber, pass the qualified synthetic rubber through the open mill for kneading and molding, and then put th...

Abstract

The present invention discloses a sealing ring for a bottom and a top cover of a filter cleaner. The sealing ring is composed of the following raw materials: chloroprene rubber CR121, hydrogenated nitrile rubber ZP2020 (Zeonex, Japan), zinc stearate, coumarone, 2-benzimidazolethiol, chlorinated paraffin, semi-reinforcing carbon black SRF, montmorillonite powder, adipate, an accelerator PZ, an accelerator TETD, a crosslinker TAC, an antiager RD, an antioxidant 1010, and modified diatomite. The sealing ring of the invention has good overall performance, high wear resistance, strong insulation, high corrosion resistance, especially high oil resistance, and low thermal deformation coefficient, and enhances functional effect of the filter cleaner. By adding a modified diatomite, rigidity and hardness of products are enhanced, the heat-resistant, wear-resistant and anti-aging performances of products are improved, and costs are significantly reduced.

Description

technical field [0001] The invention relates to the field of processing rubber composite materials, in particular to a sealing ring used for a filter bottom case and an upper cover. Background technique [0002] The traditional production of sealing rings for the filter bottom shell and the upper cover has the following problems: high thermal deformation coefficient, poor oil resistance, poor surface finish, easy to cause oil leakage, and affect the normal use of the filter , Frequent replacement of the sealing ring will lead to a waste of resources. Contents of the invention [0003] The invention provides a rubber seal ring used on the piston of a horizontal piston pusher centrifuge. [0004] In order to achieve the above object, the present invention adopts the following technical solutions: [0005] A sealing ring for filter bottom shell and upper cover, which is composed of the following raw materials in parts by weight: neoprene CR121 55-60, hydrogenated nitrile ru...
