Embodiment Construction

[0013] 1. Preparation of antioxidant additives:

[0014] 1. After hydrolyzing 1kg of trivalent cerium salt (cerium chloride or cerous nitrate), heat it to 35-40°C;

[0015] 2. Add 1 to 5 kg of organic carboxylic acid (oleic acid, benzenesulfonic acid or methyl to octadecanoic acid) dropwise in cerium chloride or cerous nitrate aqueous solution, and stir to form floccules of cerium oleate or cerium benzenesulfonate or formazan ~ cerium octadecanoate;

[0016] 3. Dry and dehydrate at 100°C to obtain a high-temperature antioxidant.

[0017] 2. Application:

[0018] 1. Weigh 1-50kg of the above antioxidant additives and mix them evenly with 1000kg of dimethyl silicone oil to make high antioxidant dimethyl silicone oil.

[0019] The high anti-oxidation simethicone oil is used as the release agent of the chemical fiber spinneret. The process requires the release agent to be kept at 300°C for more than 72 hours. The simethicone oil after adding antioxidant can last for more than ...

Abstract

A silicon oil anti-oxidizing agent relates to the technical field of chemical addition agent, in particular to the technology which can increase the silicon oil oxidation resistance, which is formed through the matching of trivalent cerium compound and organic carboxyl acid. The oxidation resistance can last for over 240 hours under the high temperature of 300 DEG C without generating polymer, when the anti-oxidizing agent whose content is 0.1-5% is added in dimethyl silicon oil and phenyl methyl silicon oil.

Description

technical field [0001] The invention relates to the technical field of chemical additives, in particular to the technology of formulations capable of improving the oxidation resistance of silicone oil. Background technique [0002] Silicone oil is a kind of non-toxic, odorless, non-corrosive, non-flammable polysiloxane liquid oil with various viscosities. Silicone oil has many special properties, such as low temperature viscosity coefficient, high and low temperature resistance, oxidation resistance, high flash point, low volatility, good insulation, low surface tension, non-corrosive to metal, non-toxic, etc. Due to these properties, silicone oils are used in many ways with excellent results. [0003] Simethicone oil has various excellent properties, so it has been widely used in various departments of industrial and agricultural production, national defense industry, scientific research and medical and health departments. It is widely used in electrical insulation, demou...
