Embodiment Construction

[0014] A nano-rust conversion agent of the present invention, each component is calculated by weight, wherein 30-45 parts of ethanol, 1.5-3 parts of salicylic acid, 100-115 parts of polyether, 1.5-2.5 parts of quinic acid, nonionic 5-7 parts of surfactant, 3-4 parts of sodium petroleum sulfonate, 240-280 parts of water.

[0015] As a further improvement of the above-mentioned technical scheme: the nonionic surfactant is a polyoxyethylene type nonionic active agent, which is a surfactant that does not generate ions in an aqueous solution, and its penetration and detergency are very good. Well, the emulsifying power is also quite strong. The solubility of nonionic surfactants in water is due to the strong hydrophilic functional groups in the molecule. Nonionic surfactants are second only to anionic surfactants in quantity, and are an important type of large-scale use. Therefore, their materials is also more convenient,

[0016] By adopting the above technical scheme, the reage...

Abstract

The invention discloses a nanometer iron rust conversion agent. The nanometer iron rust conversion agent comprises, by weight, 30-45 parts of ethyl alcohol, 1.5-3 parts of salicylic acid, 100-115 parts of polyether, 1.5-2.5 parts of quininic acid, 5-7 parts of nonionic surfactant, 3-4 parts of petroleum sodium sulfonate and 240-280 parts of water. A reagent prepared from the components is high indedusting capacity, and a rusty layer can be completely converted; meanwhile, a conversion film formed by the nanometer iron rust conversion agent is compact, tough, tensile, resistant to wear and attrition and high in corrosion resistance; meanwhile, the salicylic acid and the quininic acid belong to a weak acid and organic acid system and cause no damage to a paint film; after being treatment, aworkpiece can meet the zero emission and zero pollution standards without being neutralized or washed; and adopted materials do not contain forbidden chemicals and harmful substances and are uninflammable, nonexplosive and good in safety.

Description

technical field [0001] The present invention relates to a kind of biological reagent, more specifically, it relates to a kind of nanometer iron rust transformation agent and its preparation method. Background technique [0002] After the metal parts are processed and before the tooling is painted, the rust and oil on the surface need to be removed by traditional methods such as sandblasting, grinding, manual derusting, pickling, etc., which is very time-consuming and laborious, and will generate a lot of pollution during the process. substances, polluting the environment. At the same time, after a series of complicated processes, some rust residues in blind areas cannot be removed, which will directly affect the subsequent coating quality. If the pretreatment work before coating can be omitted, it becomes very necessary to develop new rust coatings to stably transform the rusted steel surface. Potassium dichromate, sodium nitrite, zinc, manganese, salt, etc. are often used...
