example 1
[0016] A modified EPDM rubber, which is made from the following raw materials in parts by weight:
[0017]
[0018] Plasticizer is No. 38 cylinder oil; Described lubricant is microcrystalline paraffin; Described coupling agent is silicon
[0019] Alkane coupling agent YGO-1204; the vulcanizing agent is sulfur.
[0020] The preparation method is as follows:
[0021] Add EPDM rubber, nano-montmorillonite, nano-alumina, nano-magnesia, anti-aging agent, and plasticizer into the internal mixer according to the formula ratio, start the internal mixer, fully mix several raw materials, and wait for the compaction When the temperature of the mixing room reaches 120°C, the mixed rubber material is released from the internal mixing room, put into the open mill for masticating, filtered through the rubber filter, and then rolled, and then added with a vulcanizing agent for secondary mixing, and the production The modified EPDM rubber was obtained.
