Beschreibung
Zusammenfassung:	本发明公开了一种耐高低温的密封圈用EPDM/MVQ胶料，由以下组分构成：三元乙丙橡胶80～95份；硅橡胶5～20份；炭黑40～80份；石蜡油5～10份；酯类增塑剂0～5份；硅烷偶联剂0～3份；活性剂5～15份；防老剂1～4份；硫化剂6～10份。本发明在使用环境下具有优异的耐高低温压变性能，满足制品对密封性能的需求等特点。 The invention discloses a high and low temperature resistant EPDM/MVQ rubber material for a sealing ring. The EPDM/MVQ rubber material is composed of the following components: 80-95 parts of ethylene propylene diene monomer; 5-20 parts of silicone rubber; 40 to 80 parts of carbon black; 5 to 10 parts of paraffin oil; 0-5 parts of an ester plasticizer; 0-3 parts of a silane coupling agent; 5-15 parts of an active agent; 1-4 parts of an anti-aging agent; and 6-10 parts of a vulcanizing agent. The sealing material has the characteristics of excellent high and low temperature pressure change resistance in a use environment, capability of meeting the requirements of products on sealing performance and the like.
