preparation example Construction

[0040] The preparation method of a kind of mobile phone dewaxing surfactant described in the embodiment of the present invention comprises the following steps:

[0041] Step S100, sequentially add sulfonic acid, saponins powder extract, C13 fatty alcohol polyoxyethylene ether, ethylene glycol phenyl ether and sorbitol into the reaction kettle, and fully stir.

[0042] Step S200, adding triisopropanolamine to adjust the pH value of the mixture in the reactor to a preset pH to form a reactant.

[0043] Specifically, the preset pH is 7-8, preferably, the preset pH is 7.5-7.8.

[0044] Further, while stirring, triisopropanolamine is added to adjust the pH value of the mixture in the reactor to a preset pH, and the stirring speed is 60-100 rpm.

[0045] Step S300 , after stirring the reactants evenly, heating and heat preservation is carried out, and after a predetermined time of heat preservation, the water is distilled out under reduced pressure to obtain the finished product. ...

specific Embodiment 1

[0049] Add 30 parts of sulfonic acid, 30 parts of acacia powder extract, 20 parts of C13 fatty alcohol polyoxyethylene ether, 19 parts of ethylene glycol phenyl ether and 1 part of sorbitol in the reactor; the rotating speed of the reactor is 90 rpm Minutes, where the EO number of C13 fatty alcohol polyoxyethylene ether is 3. Use triisopropanolamine to adjust the pH value of the mixture in the reaction kettle to be constant at 7.5-8, while stirring continuously; after stirring evenly, heat to 110°C, and then fully react for 3 hours, and distill the water under reduced pressure at the same time to obtain finished product. During the whole reaction process, the temperature is not lower than 85°C, otherwise it needs to be heated to between 85°C and 110°C.

specific Embodiment 2

[0051] The difference from the specific example 1 is that there are 40 parts of sulfonic acid, 8 parts of C13 fatty alcohol polyoxyethylene ether, 1 part of ethylene glycol phenyl ether and 0.2 part of sorbitol. The EO number of C13 fatty alcohol polyoxyethylene ether is 8, and the pH value is 7.5-8.

Abstract

The invention discloses a surfactant for wax removal of mobile phones and a preparation method thereof. The surfactant for wax removal of mobile phones comprises: 30-70 parts of sulfonic acid, 10-70 parts of triisopropanolamine, 10-30 parts of a gleditsia sinensis powder extract, 0.1-20 parts of C13 fatty alcohol-polyoxyethylene ether; 10-20 parts of ethylene glycol phenyl ether; and 1-10 parts ofsorbitol. The gleditsia sinensis powder extract can help the ether group of C13 fatty alcohol-polyoxyethylene ether to keep good activity, and also can help isolation, sorbitol is a humectant, and can prevent workpieces from being corroded due to sudden increase of the concentration of the dewaxing agent due to excessively fast moisture drying and contact with high-temperature gas, thus further protecting the workpieces from being corroded.

Description

technical field [0001] The invention relates to the technical field of surfactants, in particular to a surfactant for removing wax from a mobile phone and a preparation method thereof. Background technique [0002] In the prior art, due to the light weight and high strength of 6-series and 7-series aluminum materials, mobile phone manufacturers have used them in large quantities, but 6-series aluminum materials, especially 7-series aluminum materials, are not suitable for ordinary wax-removing surfactants. It is very sensitive and easy to corrode, and there are many types of ordinary wax removal surfactants, but many surfactants are not strong in wax removal and are corrosive to metals, which greatly reduces the application range of wax removal, resulting in failure It is applied on the mobile phone shell; while the surfactant with good wax removal power has the problem of severe corrosion. [0003] Therefore, the prior art still needs to be improved and developed. Conten...
