Description

Metal treatment agent and metal material surface treatment method

[ technical field ] A method for producing a semiconductor device

The invention relates to the field of metal surface treatment, in particular to a metal treating agent and a metal material surface treatment method.

[ background of the invention ]

The intermediate of the carrier lubricant used in the current market is generally phosphorized, but the phosphorized liquid contains heavy metal containing phosphorus and accelerant containing nitrate, which are easy to cause cancer after long-term use, and the phosphorized slag sludge is difficult to treat, thus bringing great pressure to the environment.

It can be seen that the provision of an improved metal treatment agent is a problem which needs to be addressed in the art.

[ summary of the invention ]

The invention aims at the problems and provides a metal treating agent and a metal material surface treatment method, which are phosphorus-free, heavy metal-free, environment-friendly and pollution-free.

In order to solve the problems, the invention provides a metal treating agent which comprises the following raw material components in percentage by weight: 10-40% of silicate, 10-20% of sodium carbonate, 1-10% of sodium stearate, 1-10% of melamine and 20-60% of sodium sulfate.

Further, the silicate accounts for 30%, the sodium carbonate accounts for 10%, the sodium stearate accounts for 5%, the melamine accounts for 10%, and the sodium sulfate accounts for 45%.

In order to solve the problems, the metal material surface treatment method provided by the invention comprises the steps of mixing a metal treatment agent and water according to the mass ratio of 1: 8-12, heating, stirring and dissolving, then putting metal into a mixed solution, soaking and taking out.

Further, the mass ratio of the metal treatment agent to water is 1: 10.

Further, the heating temperature is 70-90 ℃.

Further, the soaking time is 5-20 minutes.

Compared with the prior art, the invention has the following advantages:

1. no phosphorus, no heavy metal, environmental protection and no pollution;

2. no promoter and no harm to human body;

3. the film layer is water-soluble, and has no influence on the subsequent galvanization;

4. the residual film layer can not block the furnace hole of the heat treatment furnace.
