Dyeing flow mark inhibition additive and method for drying aluminum alloy anode

Abstract

The invention discloses a dyeing flow mark inhibition additive and a method for drying an aluminum alloy anode. The dyeing flow mark inhibition additive is prepared from the following components in parts by mass: 7.5 to 10.5 parts of nickel acetate, 3.5 to 5.5 parts of sodium acetate, 7.5 to 10.5 parts of polydimethylsiloxane, 3.5 to 5.5 parts of mannitol, 3.5 to 6.5 parts of triethanolamine and 4.5 to 6.5 parts of ammonium sulfate. The dyeing flow mark inhibition additive disclosed by the invention can inhibit conditions of blistering, PH unstability and non-uniform dyeing agent distribution of dyeing bath liquid for oxidization dyeing of the aluminum alloy anode, so that quality abnormities such as flow marks and spots during dyeing are reduced; furthermore, the dyeing capability of dyeing bath liquid can be promoted, and the service life of the dyeing bath liquid for oxidization dyeing of the aluminum alloy anode can be further prolonged from the original one week to about three weeks; and therefore, the bath building frequency is reduced, equipment operation is enhanced, and the dyeing cost is reduced.

Description

technical field [0001] The invention relates to the field of dyeing bath liquid additives, in particular to a dyeing flow mark inhibiting additive and an aluminum alloy anode dyeing method. Background technique [0002] Under normal use, the dyeing bath solution for aluminum alloy anodic oxidation dyeing is prone to mildew reaction, and then foaming, pH instability, uneven distribution of dyeing agent and decline in dyeing ability, etc., and its validity period is generally only about one week. It is easy to fail, and it is easy to cause quality abnormalities such as flow marks and mottled products. Due to the short life of the dyeing bath, it is necessary to frequently build baths (that is, to build pickling tanks or electroplating tanks in industrial applications, which means building baths), resulting in equipment grafting (that is, the equipment can provide The proportion of the time taken to create value in time. It refers to the ratio of the actual production quantity...
