Abstract

The invention discloses a phosphating agent for surface treatment on aluminum cans. The phosphating agent comprises the following raw materials in parts by weight: 22-24 parts of phosphoric acid, 5-7 parts of sodium molybdate, 8-10 parts of chromic acid, 5-8 parts of fluoride sodium borate, 2-5 parts of antimony trioxide, 2-4 parts of calcium nitrate, 3-5 parts of zinc nitrate, 1.5-2.5 parts of calcium chloride, 0.8-1.2 parts barium stearate, 0.5-1.2 parts of tribasic lead sulphate, 0.5-1.5 parts of titanium dioxide and 1.4-1.8 parts of barium metaborate. The phosphating agent can be used at room temperature; a surface adjusting procedure before phosphorization is eliminated, and a washing procedure after phosphorization is avoided; the phosphating agent belongs to an environment-friendly manganese-calcium-series phosphate solution which is simple and convenient to operate, long in service life, excellent in effect and high in adhesive force; the phosphating agent is good in stability, short in processing time, high in strength of a formed phosphate coating, excellent in adhesive force and high in corrosion resistance.

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 aluminum cans. [0003] Background technique [0004] Phosphating is a commonly used pre-treatment technology. The main purpose of phosphating is to provide protection for the base metal and prevent the metal from being corroded to a certain extent; it is used as a primer before painting to improve the adhesion and corrosion resistance of the paint film layer. ; It is used for anti-friction lubrication in metal cold working process. The existing phosphating solution has the following problems when processing workpieces: 1. The working temperature is high and the energy consumption is large; 2. The working temperature is not high, but the working time is long and the working efficiency is low. [0005] Contents of the invention [0006] The purpose of this invention is to provide a kind of phosphating agent ...
