Abstract

The invention discloses a super-amphiphobic corrosion resistant coating for rain gauge and a preparation method thereof. The super-amphiphobic corrosion resistant coating is prepared from, by weight,40-60 parts of organosilicon epoxy resin, 5-10 parts of curing agent, 10-20 parts of polytetrafluoroethylene, 10-20 parts of polyether-ether-ketone, 20-25 parts of polydopamine, 20-25 parts of oxygenbased ferric chloride modified by nano polyaniline, 5-10 parts of aluminium triphosphate, 5-10 parts of talc powder, 5-10 parts of nano silver particles, 1-3 parts of silane coupling agent, 1-2 partsof wetting agent, 0.5-2 parts of defoamer, 0.5-2 parts of dispersant and 30-50 parts of n-butyl alcohol. The super-amphiphobic corrosion resistant coating not only has good properties of high temperature resistance, high pressure resistance, strong acid resistance, strong alkali resistance, corrosion resistance and the like, but also has an excellent hydrophobic and oileophobic property and an anti fouling property, can significantly prolong the service-life of the rain gauge, and significantly improve the measurement precision of the rain gauge.
