Abstract

The invention discloses a surface treatment phosphatizing agent for a building sectional material. The surface treatment phosphatizing agent is prepared from the following raw materials in parts by weight: 10-12 parts of calcium phosphate, 15-18 parts of manganous nitrate, 4-6 parts of phytic acid, 8-10 parts of sodium fluoborate, 2-5 parts of n-butyl acetate, 2.8-3.5 parts of benzoic acid, 1.2-1.8 parts of an active monomer, 0.8-1.2 parts of nickel nitrate, 0.5-0.8 part of barium nitrite, 1.2-2.5 parts of tartaric acid, 0.4-0.8 part of triethanolamine, 1.4-2.5 parts of chromium sulfate, 2.5-3.5 parts of an initiator, 0.5-1.2 parts of a surfactant and 45-50 parts of industrial water. The manganese and calcium serial environment-friendly phosphating solution which can be used at constant temperature, free from surface adjustment step before phosphorization and washing step after phosphorization, simple and convenient to operate, long in service life, excellent in effect and strong in adhesive force can be used for overcoming the problems that conventional phosphorization is complex in process, relatively high in phosphorization temperature, great in consumption of water and phosphate and the like, much in harmful wastewater and the like.

Description

[0001] technical field [0002] The invention relates to the technical field of a phosphating solution, in particular to a phosphating agent for surface treatment of building profiles. [0003] Background technique [0004] Iron and steel parts must be treated with anti-rust treatment. The usual method is to spray paint. Before painting, in order to increase the bonding strength between the coating and the steel plate, the steel parts must be phosphating before painting, so that the outside of the steel parts is formed. A honeycomb-like structure that increases bond strength. However, the existing phosphating solution has the disadvantages of turbidity, many residues generated during the phosphating process, small patch area, high temperature requirement, and waste of labor. [0005] At present, the existing methods for treating metal surfaces not only have complex procedures, high labor intensity (especially for the treatment of rusted metal components), low efficiency, b...
