Antibacterial fluororubber composite material and preparation method thereof

The invention relates to the technical field of fluororubber materials, in particular to an antibacterial fluororubber composite material and a preparation method thereof. The antibacterial fluororubber composite material is prepared from the following preparation raw materials in parts by mass: 70 to 75 parts of fluororubber, 5 to 7 parts of epoxy resin E-51, 5 to 7 parts of a plasticizer, 3 to 5 parts of a coupling agent, 30 to 35 parts of heat-conducting filler, 5 to 8 parts of zinc oxide, 2 to 4 parts of zinc stearate, 1 to 1.5 parts of an anti-aging agent, 1 to 1.5 parts of an accelerant, 1 to 2 parts of a vulcanizing agent and 2 to 3 parts of a composite antibacterial agent, the composite antibacterial agent is composed of maleic anhydride acylated chitosan and silver-copper-zinc doped titanium dioxide in a mass part ratio of (5-7): 1. The antibacterial fluororubber composite material has the advantages of excellent mechanical property, good heat-conducting property, excellent antibacterial property, go
