Description

Soap powder and preparation method thereof

[ technical field ] A method for producing a semiconductor device

The invention relates to the field of soap powder, in particular to high-lubrication and high-rust-prevention soap powder.

[ background of the invention ]

The soap powder used in the current market has poor antirust performance, the surfaces of a plurality of workpieces are yellowed just after saponification, and the soap powder can be placed for 1 month without rusting after use. In addition, after saponification is carried out on soap powder used in the market, the cold heading machine with large deformation in the cold heading process cannot realize one-step forming, and the one-step forming is generally divided into 2-3 times, so that the production efficiency is reduced.

It can be seen that there is a need in the art to provide an improved soap powder and method for making the same.

[ summary of the invention ]

The invention aims at the problems and provides soap powder and a preparation method thereof, which are high in lubrication and rust resistance.

In order to solve the problems, the invention provides soap powder which comprises the following raw material components in percentage by weight: 40-70% of stearic acid, 10-30% of sodium hydroxide, 0-20% of calcium hydroxide, 2-10% of additive and 10-30% of water.

Further, stearic acid 60%, sodium hydroxide 20%, calcium hydroxide 5%, additive 5% and water 10%.

Further, the additive is at least one of sodium tripolyphosphate, monoethanolamine and disodium ethylene diamine tetraacetate.

The preparation method of the soap powder comprises the steps of dissolving sodium hydroxide and calcium hydroxide in water, adding the dissolved sodium hydroxide and calcium hydroxide into a kneader, heating to 85-95 ℃, adding stearic acid, fully stirring, reacting for 1.5-2 h, adding an additive, continuously stirring for 30min, cooling, and crushing by using a crusher.

Further, the heating temperature is 90 ℃.

Further, the reaction time is 2 h.

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

1. the workpiece saponified by the soap liquid is not rusted after being placed in the air for one month;

2. the drawing speed of the steel wire after the saponification treatment of the product reaches 8m/s and above, and the workpiece after the saponification of the product can be compressed into one-step forming by two-time deformation, so that the production efficiency is improved.
