VCI nano intercept-type rust-proof film

Abstract

The invention provides a VCI nano intercept-type rust-proof film. The rust-proof film is prepared from the following raw materials in parts by weight: 100-120 parts of PBT resin, 30-60 parts of a nano-copper material, 10-20 parts of graphene, 15-35 parts of ammonium dichromate, 10-20 parts of benzotriazole, 20-40 parts of o-nitrophenol dicyclohexylamine, 10-20 parts of monoethanolamine, 30-50 parts of calcium carbonate, 10-20 parts of talcum powder, 15-25 parts of a plasticizer, and 1-5 parts of a reinforcing agent. The rust-proof film is capable of solving problems that partial special products require a long rust protection period and anti-rust performance of a gas phase is not enough. A formed protective film is very thin and compact, a base color of steel is kept, and the double rust-proof protective effects are achieved.

Description

technical field [0001] The invention relates to the technical field of anti-rust film, in particular to a VCI nano interception type anti-rust film. Background technique [0002] VCI is the abbreviation of English Vapor Corrosion Inhibitor (Volatile Corrosion Inhibitor). It is a kind of corrosion inhibitor synthesized with special ingredients and has certain volatility. It is referred to as vaporized antirust product. The VCI gas phase anti-rust packaging technology is to place a certain amount of gas phase corrosion inhibitor in the packaging container or storage space, or the gas phase anti-rust paper and gas phase plastic film coated with the gas phase anti-rust agent. rust gas, forming a certain vapor pressure, filling the storage space, even the gaps of equipment components, effectively inhibiting the corrosion of metal parts. Because of this method, when using VCI, the surface, inner cavity, pipe, groove and even the gap of the metal product can be protected without d...

AI Technical Summary

Problems solved by technology

[0003] The existing VCI vapor phase anti-rust film can form a multi-layer effective ion film on the dry and clean metal surface to protect the metal parts from rusting, but it has poor resistance to the corrosive and harmful gases that continuously invade from the outside. Under corrosion, the anti-rust effect will drop significantly soon, and even cannot play the role of anti-rust, but some special products require a long anti-rust period, so the simple gas-phase anti-rust performance is not enough to solve the problem
