Abstract

The invention discloses an EPDM (Ethylene-Propylene-Diene Monomer) acrylic resin rubber sealing gasket material, which is characterized by comprising the following raw materials in parts by weight: 60-65 parts of EPDM (Lanxee 2470), 10-12 parts of acrylate rubber, 12-15 parts of phthalate esters, 3-4 parts of zinc oxide, 2-3 parts of stearic acid, 30-34 parts of carbon black, 1-2 parts of N-phenyl-1-naphthylamine, 1-2 parts of chlorotributyltin, 1-2 parts of dioctadecyl dimethyl ammonium chloride, 1-2 parts of anti-aging agent ODA, 3-4 parts of accelerator DM, 2-3 parts of sulfur, and 10-12 parts of modified attapulgite. According to the EPDM acrylic resin rubber sealing gasket material, the technological property of rubber can be improved due to the addition of the modified attapulgite, and the toxic and side effects and environmental pollution can be reduced due to the use of an environment-friendly compounding ingredient; the material has the advantages of reasonable formula, excellent mechanical property, high strength, good sealing and anti-aging properties, as well as simpleness in technology and low cost and is safe and non-toxic.

Description

technical field [0001] The invention relates to the field of processing rubber composite materials, in particular to a EPDM acrylic resin rubber sealing gasket material and a preparation method thereof. Background technique [0002] Gasket is a material used for sealing inside machinery, equipment, pipelines, etc. The gaskets currently used are mostly rubber gaskets, which are characterized by high temperature resistance, ozone resistance, natural aging resistance, vacuum resistance, fuel oil resistance, lubricating oil resistance, strong oxidant resistance, chemical resistance and good electrical insulation performance. Widely used in defense industry and civilian industry. However, the existing rubber gaskets have defects such as unsatisfactory sealing effect, poor wear resistance and low strength, which are far from meeting the actual requirements. Therefore researching and developing a kind of high-performance rubber gasket has become the task of top priority. Conten...
