Release agent and preparation method thereof

Abstract

The invention discloses a release agent and a preparation method thereof, belongs to the field of release agent and solves the problem of environment pollution caused by irritant gas generated during application of the release agent. The release agent comprises long-chain alkyl aryl silicone oil, machine oil, Span 80, nonylphenol polyoxyethylene ether, fatty glyceride, triethanolamine borate, triethanolamine and 2, 5-ditert-butylhydroquinone. The preparation method of the release agent comprises the following steps of: mixing Span 80 with nonylphenol polyoxyethylene ether to obtain an emulsifier; adding water, heating up and adding the emulsifier; mixing long-chain alkyl aryl silicone oil, machine oil, oxidized polyethlene wax and fatty glyceride; slowly adding the mixture into hot water and stirring, forming emulsion after adding all the mixture into the hot water; and orderly adding cholamine borate, 2, 5-ditert-butylhydroquinone and triethanolamine, mixing and forming the release agent. The triethanolamine is used for regulating the PH value, the 2, 5-ditert-butylhydroquinone is used for enhancing the oxidation resistance, and the two constituents both cannot generate irritant gas to pollute environment.

Description

technical field [0001] The invention relates to the field of release agents, in particular to a release agent and a preparation method thereof. Background technique [0002] The release agent is an important auxiliary material in the production process of the battery, and the automatic casting and welding machine of the battery needs the auxiliary work of the release agent. The working temperature of automatic flux is generally 400°C-500°C. The commonly used release agents are not effective at this temperature. Due to poor high temperature resistance, the release agent volatilizes too quickly, resulting in frequent need Manually add release agent, resulting in a waste of manpower. In addition, the commonly used release agents generally use ammonia water or sodium benzoate to adjust the pH value of the release agent and enhance the anti-oxidation ability. Under high-temperature working environments, these two preparations are extremely volatile, produce irritating gases, and...

Problems solved by technology

The working temperature of automatic flux is generally 400°C-500°C. The commonly used release agents are not effective at this temperature. Due to poor high temperature resistance, the release agent volatilizes too quickly, resulting in frequent need Manually add release agent, resulting in waste of manpower

In addition, the commonly used release agents generally use ammonia water or sodium benzoate to adjust the pH value of the release agent and enhance the anti-oxidation ability. Under high-temperature working environments, these two preparations are extremely volatile, produce irritating gases, and cause environmental pollution. At the same time, the volatilization of ammonia water or sodium benzoate also increases the frequency of manual addition of release agents, which further wastes manpower, and when manual addition of release agents, irritating gases are likely to cause harm to human health
