Abstract

The invention discloses a preparation method of an organosilicone ternary block copolymer. The traditional amino silicon oil softening agent has the problems of poor hydrophilicity, easiness in demulsification, floating oil, roll sticking and the like. The method comprises the steps of enabling aromatic polybasic carboxylic acid to react with a terminal hydroxyl polyethylene glycol under nitrogen protection at 140-160 DEG C for 10-14h to obtain corresponding aromatic organic acid macrogol ester; adding epoxy silicone oil and polyether polyamine to the product, adding a proper amount of catalyst employing monohydric alcohol of C1-C4 as a medium, heating the mixture to 80-90 DEG C and reacting for 24-40h to obtain the organosilicone ternary block copolymer after reaction is completed. Excellent hydrophilicity is provided while a fabric is endowed with an excellent soft and fluffy handle when the prepared copolymer is used for fabric softening.

Description

technical field [0001] The invention relates to the field of finishing agents for fabrics and textiles, in particular to a method for preparing an organosilicon ternary block copolymer. Background technique [0002] Because of its unique soft chain and low surface tension, silicone can significantly improve the hand feel of the fabric when it is used in the field of fabric finishing, making it soft, smooth, anti-wrinkle and other characteristics, and is friendly to the human body. Therefore, it is very popular. [0003] At present, amino-modified silicone is a type of silicone finishing agent with a high market utilization rate. The fabric has the characteristics of softness, smoothness and washability, but it also has some obvious defects. For example, after finishing, the fabric will show hydrophobicity, which reduces the comfort and hygroscopicity of the fabric. yellowing. In addition, since the stability of its emulsion depends entirely on the emulsifier, it is sensit...
