Embodiment 1
[0036] The invention provides a fluorescent powder coating for antibacterial electronic components, which consists of the following components by weight percentage:
[0037]
[0038] The curing agent is an organic acid or acid anhydride curing agent.
[0039] The epoxy equivalent of the epoxy resin is 3000-7000g / eq.
[0040] The preparation method of the antibacterial expanded graphite is as follows; the raw graphite that has been weighed is added to a certain proportion of mixed acid under constant stirring, and after stirring evenly, potassium permanganate and ferric chloride are added, and the mixture is heated at 25°C After the reaction, wash with water until the pH is 6-7, then dry in an oven at 75°C to obtain expandable graphite, grind the expandable graphite to 200 mesh, mix the ground expandable graphite fine powder with natural plant After the antibacterial agent is evenly mixed, it is roasted at 250° C. to obtain antibacterial expanded graphite, which is ground f...
