AI Technical Summary

Problems solved by technology

In the first step, sodium bicarbonate neutralizes concentrated sulfuric acid to produce a large amount of solid salt, which cannot be recycled and may cause environmental pollution, and the entire production process takes about 3 days
At present, there is no production method for mass production of block amino silicone oil with simple production process, no impact on the environment, and short production cycle.

Embodiment 1

[0013] 1. Precursor generation, 100 parts of octamethylcyclotetrasiloxane and 2 parts of 1,3-bis(3-glycidyl propyl)-1,1,3,3-tetramethyldisiloxane in Under the action of 2 parts of tetramethylammonium hydroxide catalyst, add 10 parts of N,N-dimethylformamide as a solvent, raise the temperature to 90°C for 12 hours, and then raise the temperature to 150°C and remove the low boiling for 2 hours under vacuum. Cool down again to obtain terminal epoxy silicone oil;

[0014] 2. For the generation of block amino silicone oil, put 100 parts of epoxy-terminated silicone oil, 7 parts of polyetheramine ED900, and 100 parts of isopropanol into the kettle, raise the temperature to 70°C for 5 hours, and cool down to obtain block amino silicone oil.

Embodiment 2

[0016] 1. Precursor generation, 100 parts of octamethylcyclotetrasiloxane and 4 parts of 1,3-bis(3-glycidyl propyl)-1,1,3,3-tetramethyldisiloxane in Under the action of 3 parts of tetramethylammonium hydroxide catalyst, add 15 parts of N,N-dimethylformamide as a solvent, raise the temperature to 100°C for 12 hours, then raise the temperature to 150°C and remove the low boiling for 2 hours under vacuum, Cool down again to obtain terminal epoxy silicone oil;

[0017] 2. Formation of block amino silicone oil, put 100 parts of epoxy-terminated silicone oil, 10 parts of polyetheramine ED900, and 110 parts of isopropanol into the kettle, heat up to 80°C for 5 hours of reaction, and cool down to obtain block amino silicone oil.

Embodiment 3

[0019] 1. Precursor generation, 100 parts of octamethylcyclotetrasiloxane and 3 parts of 1,3-bis(3-glycidyl propyl)-1,1,3,3-tetramethyldisiloxane in Under the action of 3 parts of tetramethylammonium hydroxide catalyst, 15 parts of N,N-dimethylformamide was added as a solvent, the temperature was raised to 95°C for 12 hours, and then the temperature was raised to 150°C for 2 hours to remove the low boiling point. Cool down again to obtain terminal epoxy silicone oil;

[0020] 2. For the formation of block amino silicone oil, put 100 parts of epoxy-terminated silicone oil, 8 parts of polyetheramine ED900, and 108 parts of isopropanol into the kettle, raise the temperature to 75°C for 5 hours, and cool down to obtain block amino silicone oil.

[0021] According to experimental tests, the above three specific examples can produce block amino silicone oil. In the precursor generation, 1,3-bis(3-glycidylpropyl)-1,1,3,3-tetramethyldi As the content of siloxane increases, the purity...

Abstract

The invention relates to a block amino silicone oil production method, which mainly comprises the following two steps: precursor production; and block amino silicone oil production. The block amino silicone oil production method uses no concentrated sulfuric acid and sodium bicarbonate, so that no solid salt may be produced, and the pollution of the environment may be reduced. In addition, the whole production process only needs 2 days, the production cycle is shortened, and the production time is greatly saved.

Description

technical field [0001] The invention relates to the field of textile fabric treatment, in particular to a method for producing block amino silicone oil. Background technique [0002] The relationship between human beings and chemical industry is very close. In modern life, chemical products are inseparable almost anytime and anywhere. From material life such as clothing, food, housing, and transportation to spiritual life such as culture, art, and entertainment, chemical products are required to serve them. . Some chemical products play an epoch-making important role in the history of human development. Their production and application even represent a certain historical stage of human civilization. [0003] At present, the handle treatment of textile fabrics is mainly amino silicone oil with amino groups distributed in the side chain and block amino silicone oil with amino groups distributed in the main chain. When using amino silicone oil with amino groups distributed i...
