Problems solved by technology

However, this kind of post-finishing additives generally has the following deficiencies: ①Many products are difficult to emulsify, the stability of the emulsion is poor, easy to break the emulsion, float oil, stick to the roller, and will form silicone oil spots that are difficult to remove on the processed fabric; ②Poor compatibility, Difficult to use in the same bath with other additives (especially additives with different charges); ③Due to the oxidation of amino groups, it is easy to cause yellowing and discoloration of the fabric; ④The finished fabric is hydrophobic and does not absorb sweat; ⑤The finished fabric It is not easy to repair the color, and it is generally necessary to remove the silicone oil before it can be repaired and dyed; ⑥ Some finished fabrics are prone to pinholes or even tear the fabric during sewing
[0005] However, at present, most of the three-component copolymerization block silicone oils use isopropanol or ethylene glycol monobutyl ether as the solvent in the synthesis process and the amount is large. Reducing the amount of solvent used in the synthesis of silicone oil has become a difficult problem

Abstract

The invention provides a method for synthesizing low-solvent ternary copolymerized block silicone oil, which is characterized in that it comprises the following steps: 1) In a reaction vessel, add hydrogen-terminated silicone oil with a molecular weight of 13000-15000 and heat it up to 80-90 ℃, 2) Add allyl glycidyl ether and catalyst chloroplatinic acid, heat and keep the temperature at 115‑126 °C, and react for about 2 hours, 3) Add polyetheramine ED‑2003, and at the same time add 2‑methyl‑2, 4-pentanediol and ethylene glycol monobutyl ether are reacted at 140-150°C for 6-8 hours, and the pH is adjusted to 6-7 with glacial acetic acid to obtain the product. The present invention uses a mixed solvent composed of 2-methyl-2,4-pentanediol and ethylene glycol monobutyl ether to reduce the amount of solvent used in the synthesis, and simultaneously uses 13000-15000 molecular weight hydrogen-terminated silicone oil and polyetheramine ED- Synthesized in 2003, with excellent hand feeling.

Description

technical field [0001] The invention relates to a method for synthesizing low-solvent terpolymerized block silicone oil. Background technique [0002] Before the popularization of block silicone oil, amino silicone oil emulsion was the main finishing aid widely used in the market. However, such post-finishing additives generally have the following deficiencies: ①Many products are difficult to emulsify, and the stability of the emulsion is poor, easy to break the emulsion, float oil, stick to the roller, and will form silicone oil spots that are difficult to remove on the processed fabric; ②Poor compatibility, Difficult to use in the same bath with other additives (especially additives with different charges); ③Due to the oxidation of amino groups, it is easy to cause yellowing and discoloration of the fabric; ④The finished fabric is hydrophobic and does not absorb sweat; ⑤The finished fabric It is not easy to repair the color, and it is generally necessary to remove the sil...
