Abstract

The invention provides a multifunctional metal surface composite treatment agent and a preparation method and a use method thereof. The multifunctional metal surface composite treatment agent comprises the following ingredients: water, manganese phosphate, magnesium chloride, sodium chloride, sodium alkyl benzene sulfonate, sodium tripolyphosphate, vegetable tannin, ethylene glycol, hydroxy acid, tartaric acid, methyl acid, polybrominated biphenyls, polybrominated diphenyl ethers, veratrole, sodium phosphate and peregal. Traditional metal surface treatment needs to adopt such processes as deoiling, dedusting and passivating, however, by use of the multifunctional metal surface composite treatment agent, only one process is needed, that is, effects of the multiple processes of the traditional metal surface treatment method can be achieved so long as metal to be treated is immersed into a soaking pool in which the multifunctional metal surface composite treatment agent is placed to be soaked for a period of time, so that the manual cost and the equipment cost are greatly lowered, and the working efficiency is improved.

Description

technical field [0001] The invention relates to a metal surface composite treatment agent, in particular to a metal surface multifunctional composite treatment agent and its preparation method and application method. Background technique [0002] At present, most of the metal surface treatments at home and abroad use chemical methods to treat the metal surface, and often have to go through several processes, such as degreasing, rust removal, phosphating, passivation, etc. to obtain a reliable surface. [0003] At present, several processes such as degreasing, rust removal, phosphating, and passivation are commonly used in metal surface treatment. First of all, it causes environmental pollution, and processing enterprises must treat the waste liquid, otherwise they must not discharge it. Even so, the damage to the environment caused by this process is still very serious; secondly, there are many processes, low efficiency and high cost; Finally, labor protection has also beco...
