Problems solved by technology

[0003] (1) Under the action of light and heat, it is easy to turn yellow;
[0004] (2) Natural fiber will make it lose hydrophilicity and affect its effect;
[0005] (3) It is difficult to meet special needs such as high resilience, washability, and high fluffiness;
[0006] (4) Amino silicone oil cannot be self-emulsified, and an emulsifier needs to be added, which affects the color fastness of the fabric and the fabric is easy to fade;
[0008] (6) Fabrics containing this kind of softener are prone to sticking to rollers and cylinders during the production process

Abstract

The invention discloses polyether polyamine which is characterized by having a following general formula: H2NC3H6(OC3H6)a(OC2H4)b(OC3H6)aNHCH2CH(OH)CH2(OC2H4)cOCH2CH(OH)CH2NHC3H6(OC3H6)dNH2, wherein the a, b, c and d are all integers from 2-40. The polyether polyamine provided by the invention contains amino groups at chain ends, has amino groups in the chain middle part, and has the improved content of the amino groups in comparison with that of the amino groups of the conventional polyether polyamine, and the flexibility of polyether polyamine block silicone oil prepared by using the polyether polyamine as one of raw materials is greatly improved.

Description

technical field [0001] The invention relates to an amino polyether and a preparation method thereof, an amino polyether block silicone oil and a preparation method thereof. Background technique [0002] At present, amino silicone oil is mostly used as textile softener in the market, so it is also known as the king of softeners. Amino silicone oil is formed by bulk polymerization of N-2-aminoethyl-3-aminopropylmethyldimethoxysilane coupling agent (ie KBM-602) and octamethylcyclotetrasilane (ie D4). The chain contains amino groups, so it can play a softening role. But this kind softener has the following disadvantages simultaneously: [0003] (1) Under the action of light and heat, it is easy to turn yellow; [0004] (2) Natural fiber will make it lose hydrophilicity and affect its effect; [0005] (3) It is difficult to meet special needs such as high resilience, washability, and high fluffiness; [0006] (4) Amino silicone oil cannot be self-emulsified, and an emulsifie...
