Problems solved by technology

Although the process is simple and convenient, the hydroxyl silicone oil emulsion is extremely unstable, and it is easy to break the emulsification floating oil and leave silicon spots and other defects on the cloth surface, and the amino silicone oil emulsion is very easy to cause yellowing on white or light-colored fabrics

Embodiment 1

[0015] (1). In a 1000L reactor equipped with a stirrer, a thermometer, and vacuum recovered materials, add 1,3-diglycidyl etheroxypropyl-1,1,3,3-tetramethyldisiloxane 300 kg, 60 kg of butanediamine, 50 kg of isopropanol were added, and reacted at a temperature of 82° C. for 3 hours to obtain amino-terminated small molecule intermediate A. Under the condition of stirring, add 130 kilograms of epoxy-terminated polyoxyethylene polyoxypropylene ether with a molecular weight of 400, and continue to react for 7 hours to obtain amino-terminated polyether-modified silicone oil intermediate B, which is cooled to below 60°C. Add 60 kg of methyl polyoxyethylene epoxy ether with a molecular weight of 200, react at a temperature of 70° C. for 5 hours, and remove the isopropanol solvent under reduced pressure to obtain a methyl-terminated polyether-modified silicone oil.

Embodiment 2

[0018] (1). Add 1,3-diglycidyl etheroxypropyl-1,1,3,3-tetramethyldisiloxane in a 1000L reactor equipped with a stirrer, thermometer, and vacuum recovery materials 400 kg, 80 kg of butanediamine, 70 kg of isopropanol were added, and reacted at a temperature of 75° C. for 5 hours to obtain amino-terminated small molecule intermediate A. Under the condition of stirring, add 95 kg of epoxy-terminated polyoxyethylene polyoxypropylene ether with a molecular weight of 300, and continue to react for 6 hours to obtain amino-terminated polyether-modified silicone oil intermediate B, which is cooled to below 60°C. Add 80 kg of methyl polyoxyethylene epoxy ether with a molecular weight of 300, react at a temperature of 82° C. for 4 hours, and remove the isopropanol solvent under reduced pressure to obtain a methyl-terminated polyether-modified silicone oil.

Abstract

The invention relates to a preparation method of a non-yellowing fluffing agent, belonging to the organic synthesis and high-molecular polymerization reactions in the fields of chemical industry and high polymer chemistry. The method is characterized by comprising the following steps: preparing methyl-terminated polyether modified silicone oil for the non-yellowing fluffing agent, emulsifying to obtain a methyl-terminated polyether modified silicone oil emulsion, and compounding with fatty acid amide compounds, glacial acetic acid and deionized water to obtain the non-yellowing fluffing agent. By adopting the technical scheme, the method provided by the invention has the advantages and positive effects that in the prepared methyl-terminated polyether modified silicone oil with a novel structure, a hydrophilic polyether group is introduced to the chemical structure, thus the methyl-terminated polyether modified silicone oil has self-emulsifying property and is very convenient to emulsify; the prepared silicone oil emulsion has stable properties such as high-temperature resistance, acid-base resistance and no demulsification; meanwhile, by adopting methyl to terminate silicone oil, the existence of primary amine on the silicone oil chain is replaced, and the defects such as yellow spots of the silicone oil emulsion on the fabric are avoided.

Description

technical field [0001] The invention relates to a method for manufacturing a non-yellowing fluffing agent, which belongs to organic synthesis and polymer polymerization in the fields of chemical industry and polymer chemistry. Background technique [0002] In the textile printing and dyeing industry, especially in the polyester printing and dyeing process, after the fiber filament is processed into gray cloth, it needs to go through the napping process to obtain the fine and dense fluff of the required length. The napping process is to pass the fabric through a series of napping rollers covered with wire card clothing, and the needle point of the metal card clothing picks up the fibers of the fabric, and generates fluff after the hook is broken. In this process, a large amount of napping agent needs to be added to make the fabric nap The fleece is fluffy and easy to handle. If no fluffing agent is added, it will inevitably lead to surface defects such as broken wool and pin...
