Abstract

The invention relates to an aluminum and aluminum alloy normal-temperature environmental-friendly sealant which is prepared from the following raw materials with the mass weight, accounting for 1L: 10-20g of hole sealing salts, 0.5-1.5g of an oxidant, 0.3-2g of a stabilizer, 0.2-6g of an accelerator, 0.2-3g of a wetting agent, 2-15g of a pH buffer and deionized water with the addition amount to be the amount obtained by after mixing the other raw materials, adding the deionized water, and fixing the volume to 1L. The aluminum and aluminum alloy normal-temperature environmental-friendly sealant has the advantages that in the sealant, each component has the unique action in a formula, so that the permeability is good, the hole sealing speed is rapid, and the hole sealing quality is high; the sealant is good in chemical stability, does not contain elements including fluorine and nickel, is safe and environment-friendly, is easy in biodegradation and does not pollute the environment; in addition, the sealant is simple in maintenance, clean in operation environment and harmless to a human body; and meanwhile, the hole sealing technology is simple and is low in energy consumption.

Description

technical field [0001] The invention belongs to the technical field of sealing agents for anodic oxidation films of aluminum and aluminum alloys, and in particular relates to a normal-temperature environment-friendly sealing agent for aluminum and aluminum alloys and a preparation method thereof. Background technique [0002] Aluminum and aluminum alloys are widely used in daily necessities, medical, construction and decoration fields, such as door and window profiles, curtain wall profiles, general profiles and industrial profiles, etc. As we all know, aluminum and aluminum alloy products have the disadvantage of being easily corroded. [0003] At present, anodic oxidation technology is widely used in the actual production process. Anodic oxidation technology is to form a layer of porous oxide film on the surface of aluminum alloy profiles, so as to protect the aluminum base layer. However, the anodized film is a porous layered structure with high porosity, strong physical...
