Embodiment 1

[0028] In a four-necked flask equipped with a thermometer, a reflux condenser and an electric stirrer, add 9g of formula (1) structure 60g formula (2) structure 369g of isopropanol, heated with a water bath, slowly warming up, when the temperature is controlled at 40°C, pre-react for 1 hour, then continue to heat up to 60-70°C, slowly add 300g of formula (3) end epoxy silicone oil dropwise to In the diamino-based polyether (i.e. the substance of the formula (2)) and the tertiary amino-based polyether (i.e. the substance of the formula (1)), the temperature is slowly raised to 70-90°C, and the reaction time is controlled at 5-25 hours. After the end, lower the temperature to below 40°C, add 7 parts of glacial acetic acid, and slowly add 2237 parts of deionized water to obtain a block polyether elastic silicone softener.

Embodiment 2

[0031] In a four-necked flask equipped with a thermometer, a reflux condenser and an electric stirrer, add 55g of the formula (4) structure 30g of formula (2) structure 385g of isopropanol, heated in a water bath, and slowly raised the temperature. When the temperature was controlled at 35°C, pre-reacted for 1 hour, and then continued to heat up to 60-70°C, slowly added 300g of formula (5) end epoxy silicone oil to the In the diamino-based polyether (i.e. the substance of formula (2)) and the tertiary amino-based polyether (i.e. the substance of formula (4)), the temperature is slowly raised to 70-90°C, and the reaction time is controlled at 5-25 hours. After the end, lower the temperature to below 40°C, add 7 parts of glacial acetic acid, and slowly add 2303 parts of deionized water to obtain a block polyether elastic silicone softener.

Embodiment 3

[0034] In a four-necked flask equipped with a thermometer, a reflux condenser and an electric stirrer, add 55g of formula (4) structure 65g formula (6) structure 420g of isopropanol, heated in a water bath, and slowly raised the temperature. When the temperature was controlled at 45°C, pre-reacted for 1 hour, and then continued to heat up to 60-70°C, slowly added 300g of formula (5) epoxy silicone oil to the In the diamino-based polyether (i.e. the substance of the formula (6)) and the tertiary amino-based polyether (i.e. the substance of the formula (4)), the temperature is slowly raised to 70-90°C, and the reaction time is controlled at 5-25 hours. After the end, lower the temperature to below 40°C, add 7 parts of glacial acetic acid, and slowly add 2513 parts of deionized water to obtain a block polyether elastic silicone softener.

Abstract

The invention relates to a block polyether elastic silicone softener and its preparation method and application. An existing silicone softener with a body structure has good softness and smoothness of the fabric treated with it, and has excellent elasticity, but this softener needs to be emulsified with a large amount of emulsifier, and the product stability is not good. Therefore, it is not conducive to widespread use. The present invention adopts three kinds of compounds having general formula A, general formula B and general formula C to prepare a kind of organic silicon softener of novel network structure through epoxy addition reaction, change softener structure to (An1Bn2Cn3)p, n1 is 1‑3, n2 is 1‑3, n3 is 1‑3, p is 1‑10. The block polyether silicone softener of the present invention can endow the fabric with a soft, slippery, fluffy and elastic hand feel, especially its excellent elastic hand feel style characteristics, and has self-emulsification and excellent acid, alkali and salt resistance. properties such as chemical stability.

Description

technical field [0001] The invention relates to the field of textile finishing, in particular to a block polyether elastic silicone softener and its preparation method and application. Background technique [0002] During the dyeing and finishing process, fiber fabrics are treated with strong alkali, resins, dyes / printing paints and other chemicals, as well as thermomechanical effects, and the fiber structure will be deformed, resulting in stiff and rough hand feeling of the fabric. Therefore, soft and smooth treatment is an indispensable and important step in the finishing process. Silicone is the most popular type of softener in the textile industry. It has developed from the initial mechanical blending type to today's multifunctional microemulsion. Modified polysiloxane emulsion fabric finishing agent has excellent softening effect and has been widely used, but there is also the problem that the emulsion breaks and sticks to the roller, which leads to the problem of sili...
