Environment-friendly neutral oil and rust removing passivator

Abstract

The invention discloses an environment-friendly neutral oil and rust removing passivator. The environment-friendly neutral oil and rust removing passivator comprises, by weight, 10-12 parts of zinc lactate, 8-10 parts of magnesium lactate, 7-10 parts of citric acid, 6-8 parts of calcium stearoyl lactylate, 5-8 parts of diacetyl tartaric acid ester of mono(di)glycerides, 5-8 parts of calcium formate, 5-6 parts of di-thiophosphoric acid amine, 8-10 parts of trimethylsiyl phosphate, 8-12 parts of oxalic acid, 10-12 parts of lauryl sodium sulfate, 8-10 parts of diethanol amine, 9-10 parts of alcohol alkoxylate, 5-8 parts of polyester modified polysiloxane, 5-8 parts of sodium lauryl polyoxyethylene ether sulfate and 5-8 parts of deionized water. The environment-friendly neutral oil and rust removing passivator has oil and rust removal, polishing and passivation combined effect together, and is simple in production process, low in corrosion to metal bases, wide in application and capable of protecting metal surfaces and preventing further metal corrosion after cleaning. In addition, the passivator can play a role in passivation and is good in anti-rust performance and capable of realizing polishing.

Description

technical field [0001] The invention relates to the technical field of a passivating agent, in particular to an environment-friendly neutral degreasing and rust-removing passivating agent. Background technique [0002] The derusting treatment of metal surfaces such as steel surfaces is the basic process before steel surface coating. At present, there are three methods for derusting treatment of steel surfaces: mechanical treatment, chemical treatment, and electrochemical treatment. Among them, chemical derusting treatment is due to its operation. Simple, low cost and good effect, so it is widely used. However, the acid solution and derusting liquid used in large quantities in the chemical derusting treatment currently used are likely to cause the reduction of the strength of the steel itself. At the same time, for the steel surface treated in this way, it is easy to be corroded again after cleaning, and This type of derusting treatment is mainly suitable for the treatment o...

Problems solved by technology

However, the acid solution and derusting liquid used in large quantities in the chemical derusting treatment currently used are likely to cause the reduction of the strength of the steel itself. At the same time, for the steel surface treated in this way, it is easy to be corroded again after cleaning, and This type of derusting treatment is mainly suitable for the treatment of the surface of ferrous metals such as steel and cast iron, but it cannot be applied well to the derusting and degreasing of other metals such as aluminum, copper and bronze, and the scope of application is small
