preparation example Construction

[0029] The present invention also proposes a method for preparing the dehydrating agent as described above, comprising the following steps:

[0030] Mix alcohol ether solvents, phase transfer catalysts, long-chain primary amines and short-chain carboxylic acids evenly, and react at 23-27°C for 20-30 minutes to obtain a dehydrating agent.

[0031] The present invention does not limit the feeding order of alcohol ether solvents, phase transfer catalysts, long-chain primary amines, and short-chain carboxylic acids. Preferably, alcohol ether solvents are added first, and then phase transfer catalysts are added. After stirring and dissolving, sequentially add The order of addition of long-chain primary amine and short-chain carboxylic acid makes the color, state, effect and stability of the hydrocarbon water cutting agent finally prepared by the dehydrating agent better.

[0032] The present invention improves the composition and proportion of the dehydrating agent, so that the pre...

Embodiment 1

[0041] (1) Weigh raw materials: 33.25g dimethyl propylene glycol methyl ether (66.5%), 3.5g methyl trioctyl ammonium chloride (7%), 7.25g dodecylamine (14.5%), 6g octanoic acid (12% ).

[0042] (2) Add dimethyl propylene glycol methyl ether into the reaction kettle, then add methyl trioctyl ammonium chloride, stir and dissolve, then add dodecylamine and octanoic acid in turn, and stir for 30 minutes at 25°C to form a transparent reaction The product N-(dodecyl) octyl amide is a dehydrating agent.

Embodiment 2

[0044] (1) Weigh raw materials: 30g ethylene glycol tert-butyl ether (60%), 2.5g methyl trioctyl ammonium chloride (5%), 5g tetradecylamine (10%), 7.5g hexanoic acid (15%) %).

[0045](2) Add ethylene glycol tert-butyl ether into the reaction kettle, then add methyl trioctyl ammonium chloride, stir to dissolve, then add tetradecylamine and hexanoic acid, and stir for 25 minutes at 27°C to form a transparent The reaction product, N-(tetradecyl)hexylamide, is the dehydrating agent.

Abstract

The invention discloses a dehydrating agent, a preparation method of the dehydrating agent, a hydrocarbon water cutting agent and a preparation method of the hydrocarbon water cutting agent, and relates to the technical field of chemical cleaning. The dehydrating agent comprises the following components in percentage by mass: 60-80% of an alcohol ether solvent, 5-10% of a phase transfer catalyst,10-20% of long-chain primary amine and 5-15% of short-chain carboxylic acid. The dehydrating agent provided by the invention has a good dehydrating effect and relatively high efficiency, the adsorption film on the surface of the part enables the part not to easily condense water and adsorb dust, and the dehydrating agent can be widely applied to electroplating pretreatment of the part, so that thesubsequent electroplating effect is ensured.

Description

technical field [0001] The invention relates to the technical field of chemical cleaning, in particular to a dehydrating agent and a preparation method thereof, a hydrocarbon water cutting agent and a preparation method thereof. Background technique [0002] In the field of electronic components with higher and higher material requirements and processing precision requirements, the surface plating requirements for precision hardware parts have also become more stringent. The surface cleanliness in the traditional sense can no longer meet its processing requirements, so it is necessary to have Higher molecular-level cleanliness than traditional requirements is required to meet the nano-level surface plating conditions to meet the high-precision specifications and high-performance reliability of electronic components. Therefore, the cleaned parts must not have water stains left, and the cleaned parts must have a certain anti-wetting ability and surface electrostatic ability to...
