Problems solved by technology

[0003] 1. The water solubility of triethanolamine oleic acid soap is poor, and a large amount of solvent and co-solvent are required to dissolve it when preparing wax removal water. The wax removal water prepared in this way has low viscosity and poor timeliness
[0004] 2. The compatibility of triethanolamine oleic acid soap in the formula is poor, and the selection of compatible surfactants is relatively small, and the formula selection for formula engineers is relatively simple

Embodiment 1

[0025] The present embodiment provides a kind of preparation method of the novel oleic acid soap that high-efficiency industrial dewaxing is used, and 45g cottonseed oleic acid is dropped in the 250ml three-necked flask that thermometer and agitator are housed, drop into 40g of hydroxyethyl ethylenediamine to the three-necked flask, Heat up to above 90°C with stirring, keep warm for 60 minutes, put 2g of 35% hydrogen peroxide into the three-necked flask, raise the temperature to 105°C, keep warm for 2 hours, put 15g of coconut oleic acid diethanolamide into the three-necked flask, stir and cool down to below 40°C That is, the finished product of novel oleic acid soap is obtained, and the appearance of the finished product is brown transparent liquid.

Embodiment 2

[0027] This embodiment provides a method for preparing a novel oleic acid soap for high-efficiency industrial wax removal. 40g of cottonseed oleic acid is put into a 250ml three-necked flask equipped with a thermometer and a mechanical stirring device, and 45g of hydroxyethylethylenediamine is dropped into the three-necked flask. , heat up to above 90°C with stirring, keep warm for 60 minutes, put 2g of 35% hydrogen peroxide into the three-necked flask, heat up to 105°C, keep warm for 2 hours, put 20g of coconut oleic acid diethanolamide into the three-necked flask, stir and cool down to 40°C The following is the finished product of novel oleic acid soap, and the appearance of the finished product is a sepia transparent liquid.

Embodiment 3

[0029] Put 45g of furfuric acid into a 250ml three-necked flask equipped with a thermometer and a stirring device, put 44g of hydroxyethylethylenediamine into the three-necked flask, heat up to above 90°C under stirring, keep it warm for 60 minutes, and put 2g of 35% hydrogen peroxide into the three-necked flask , heat up to 105°C, keep warm for 2 hours, put 10g of coconut oleic acid diethanolamide into a three-necked flask, stir and cool down to below 40°C to obtain the finished product of novel oleic acid soap, and the appearance of the finished product is brown transparent liquid.

Abstract

The invention discloses a preparation method of novel oleate soap for efficient industrial wax removal and a product thereof. The preparation method comprises the following steps: (1) preparing the following raw materials in percentage by mass: 40%-50% of oleic acid, 30%-40% of hydroxyethyl ethylenediamine, 1%-3% of a catalyst and 10%-20% of coconut oil diethanolamide; and (2) heating: mixing theoleic acid, hydrogen peroxide, coconut oil diethanolamide and hydroxyethyl ethylenediamine, and heating to react, thereby obtaining the novel oleate soap for efficient industrial wax removal. The preparation method provided by the invention is simple in steps and easy to implement; the oleate soap generated by the reaction of oleic acid and hydroxyethyl ethylenediamine is reasonably selected as amain component for cleaning, the stripping effect on wax scale is extremely strong, the synergistic effect of coconut oil diethanolamide is assisted, and the prepared novel oleate soap is high in water solubility, good in wax removal effect, excellent in emulsifying and dispersing performance, high in foaming capacity and fine in foam.

Description

technical field [0001] The invention belongs to the technical field of high-efficiency industrial wax removal, and in particular relates to a novel oleic acid soap for efficient industrial wax removal and a preparation method thereof. Background technique [0002] Wax removal is the first process of pre-treatment of metal electroplating parts. The speed and thoroughness of wax removal are of great significance to the production of electroplating lines. Therefore, choosing a good wax removal water can improve the efficiency of electroplating, thus bringing good economic benefits. At present, an important raw material for preparing wax removal water is oleic acid soap. The commonly used triethanolamine oleic acid soap, although the effect of wax removal is acceptable, has two major disadvantages: [0003] 1. The water solubility of triethanolamine oleic acid soap is poor, and a large amount of solvent and co-solvent are needed to dissolve it when preparing wax removal water. ...
