Abstract

The invention discloses an anticorrosive high-speed gear case and a preparation method thereof. The surface of the high-speed gear case is coated with a layer of an anticorrosive coating which is prepared by compounding a component A and a component B according to a ratio of 2: 1. The component A comprises, by mass, 22 to 26 parts of organosilicon-modified epoxy resin, 25 to 28 parts of pigment, 10 to 13 parts of a filling material, 9 to 13 parts of a plasticizer, 4 to 8 parts of a dispersing agent, 20 to 23 parts of itaconic acid, 19 to 25 parts of a film-forming aid, 9 to 14 parts of an antifoaming agent and 11 to 14 parts of active carbon. The component B comprises, by mass, 18 to 24 parts of polyphenyl ether resin powder, 13 to 16 parts of styrene butadiene rubber, 13 to 18 parts of toluene, 6 to 10 parts of a plasticizer, 8 to 11 parts of a leveling agent, 11 to 14 parts of silica, 9 to 15 parts of a coupling agent, 2 to 4 parts of an auxiliary material, 45 to 49 parts of water and 9 to 15 parts of a fire retardant. The anticorrosive high-speed gear case is reduced in a rejection rate and production cost and improves work efficiency.
