Abstract

The invention relates to modification of aluminum profiles, in particular to a preparation method of the bright and anticorrosive aluminum profiles. The preparation method successively comprises the steps that a bright anticorrosive solution is prepared from the components in parts by weight: 20-40 parts of sodium fluoride, 30-60 parts of ammonium bifluoride, 10-20 parts of potassium permanganate,40-50 parts of potassium chromate, 15-25 parts of zinc phosphate, 8-18 parts of sodium nitrate, 5-12 parts of praseodymium chloride, 10-16 parts of ethylenediamine tetraacetic acid, 7-14 parts of malic acid, 8-12 parts of sodium dodecyl phenyl sulfate, 6-13 parts of nickel sulfate, 15-25 parts of triethanolamine, and 500-900 parts of water; a pH valve is controlled to be 3-4 to obtain the brightand anticorrosion solution; the bright and anticorrosion solution is heated to 30-40 DEG C, and then the aluminum profiles are dipped into the bright and anticorrosion solution for 2-4 mins; then hotair circulation drying is conducted at the temperature of 80-95 DEG C for 40-50 mins; and second-time dipping is conducted under the condition of a microwave vacuum, then microwave treatment is conducted for 3-7 s in the bright and anticorrosion solution after first-time dipping treatment, washing is conducted with flowing water until a pH value of eluate is neutral, and then drying is conducted at 40-48 DEG C. The prepared aluminum profiles are bright and soft, superior in corrosion resistance, safe, and environmentally friendly.

Description

technical field [0001] The invention relates to the modification of aluminum profiles, in particular to a method for preparing bright and anti-corrosion aluminum profiles. Background technique [0002] Aluminum alloy profiles for construction require high comprehensive performance such as corrosion resistance, weather resistance, wear resistance, good appearance decoration and long service life. Therefore, aluminum profiles are protected by electrostatic powder spraying and fluorocarbon resin paint coating. Before decoration, surface chemical conversion treatment is necessary to improve the bonding force between the coating and the substrate and meet the high corrosion resistance requirements. [0003] CN102828073B (2014-1-8) discloses a production method of a powder-coated aluminum alloy profile, but the performance of the aluminum alloy profile still needs to be improved. Contents of the invention [0004] The purpose of the present invention is to provide a bright and ...
