Abstract

The invention relates to the field of sealing structural parts, and particularly discloses a metal rubber composite plate with high compression performance. The metal rubber composite plate comprises a metal base material and an ethylene propylene diene monomer layer compounded on the surface of the metal base material, wherein the ethylene propylene diene monomer layer comprises pretreated ethylene propylene diene monomer raw rubber, nitrile rubber raw rubber, sulfur, an alkyl phenolic resin cross-linking agent, an anti-aging agent, stearic acid, activated zinc oxide, carbon black, naphthenic oil, organic modified montmorillonite and an accelerant EG-4; the preparation method comprises the following steps: firstly, carrying out surface treatment on the metal base material, then preparing the ethylene propylene diene monomer layer through mixing and pressure casting, and finally compounding the ethylene propylene diene monomer layer on the surface of the metal base material and carrying out vulcanization treatment. The metal rubber composite plate can be used as a rubber sealing element, and has the advantages of being hydrophobic, oleophobic and good in sealing effect; in addition, the preparation method provided by the invention has the advantages that the sizing material is easy to disperse uniformly, the vulcanization process is simple, the adjustment is convenient, and blooming is not easy.

Description

technical field [0001] The present application relates to the field of sealing structures, and more particularly, to a metal-rubber composite plate with high compressibility. Background technique [0002] Rubber seals are a kind of general basic components in sealing devices, mainly to solve the problems of leakage and poor sealing, and play an important role in reducing leakage and environmental pollution. Rubber seals are a type of rubber products widely used in sealing technology. At the same time, because rubber products are made of elastic polymer materials, they have a wide temperature range and are given less stress in different media. Larger deformation, this deformation can provide contact pressure, compensate the leakage gap, so as to achieve the purpose of sealing. [0003] Rubber seals are used to seal and prevent leakage by cutting metal rubber-coated sheets into specific shapes and installing them at pipe connections, vacuum instruments, compressor seals, and ...
