Abstract

The invention discloses an aluminum environment-friendly nickel-free sealing agent and a preparation method and sealing method of the aluminum environment-friendly nickel-free sealing agent. The sealing agent is prepared from, by weight, 10-30 parts of lithium acetate, 0.5-2 parts of sodium persulfate, 0.5-2 parts of glacial acetic acid, 30-50 parts of potassium fluoride dihydrate and 5-20 parts of sodium fluoride. The preparation method and sealing method of the aluminum environment-friendly nickel-free sealing agent are easy and efficient, and the aluminum environment-friendly nickel-free sealing agent contains no nickel or other controlled substance, and is environmentally friendly.

Description

technical field [0001] The invention relates to an aluminum environment-friendly nickel-free sealing agent, a preparation method and a sealing method thereof. Background technique [0002] The water-soluble sealant is a water-based system with high anti-corrosion performance and strong adhesion. It does not contain harmful substances such as formaldehyde, benzene, and heavy metals. It is beneficial to environmental protection and the physical and mental health of the operator. It becomes a transparent and bright film after drying layer, can be used as the final anti-corrosion coating, and can also be used as an anti-rust primer. The current sealing agent usually contains fluorine, nickel and other substances. After sealing the anodized film layer, a large amount of waste water, nickel and other harmful elements will be generated, which will cause serious harm to the environment. Contents of the invention [0003] The technical problem to be solved by the present invention...
