Embodiment 1
[0017] A self-lubricating silicone rubber, comprising the following components in parts by weight: 100 parts of methyl vinyl silicone rubber, 20 parts of fumed silicon dioxide, 3 parts of hydroxy silicone oil, 0.5 parts of fluorine release agent, methyl phenyl silicone oil 20 parts, 7 parts of magnesium oxide.
[0018] The preparation method of described self-lubricating silicone rubber, comprises the steps:
[0019] (1) Weigh each component by formula;
[0020] (2) Put the methyl vinyl silicone rubber into the kneader and knead it;
[0021] (3) Add fumed silica into the kneader in batches and mix and knead with methyl vinyl silicone rubber. During this process, add hydroxy silicone oil, fluorine release agent, methyl phenyl silicone oil and magnesium oxide, mix well and then heat up 160°C, continue kneading for 2 hours after forming a dough;
[0022] (4) cooling and filtering the product obtained in step (3) to obtain the self-lubricating silicone rubber.
