Problems solved by technology

[0005] Aiming at the defects of the prior art, the present invention provides a highly stable anti-phenol yellowing silicone oil softener and a preparation method thereof. By compounding and screening the components of the silicone oil softener, a kind of softener with both stability and stability is finally obtained. A softener with high grade of phenol yellowing and excellent hand feeling, which solves the technical problems that the amino group in the silicone oil chain segment of the softener in the prior art causes the phenol yellow to become larger, and the compatibility of the softener components and the anti-phenol yellowing agent is not good, etc.

Abstract

The invention belongs to the technical field of textile softeners, and particularly relates to a high-stability phenol-yellowing-resistant silicone oil softener and a preparation method thereof. The high-stability phenol-yellowing-resistant silicone oil softening agent is prepared from the following components in parts by mass: 5 to 40 parts of silicone oil, 2 to 20 parts of an emulsifier, 0.2 to 1 part of a co-emulsifier, 2 to 15 parts of a solvent, 0.5 to 5 parts of a phenol-yellowing-resistant agent and 15 to 120 parts of deionized water. The softening agent provided by the invention overcomes the difficulties of serious phenolic yellowing of high-amine-value silicone oil and poor compatibility of an anti-phenolic yellowing agent and the softening agent by preferably selecting reasonable raw materials, has excellent phenolic yellowing resistance and soft hand feeling, also has good acid resistance, alkali resistance, roll sticking resistance, shear resistance, centrifugation, compounding stability and other stability, and is suitable for industrial production. And industrial use requirements and export requirements are met.

Description

technical field [0001] The invention belongs to the technical field of textile softeners, and more particularly relates to a highly stable anti-phenolic yellowing silicone oil softener and a preparation method thereof. Background technique [0002] Textiles often appear yellowing during transportation and storage, and the most common one is phenolic yellowing. The cause of phenolic yellowing is that most of the packaging materials used in fabrics will add phenolic antioxidants, such as 2,6-di-tert-butyl-4-methylphenol (BHT for short). Due to the small solubility of BHT in packaging materials, it will be transferred to the surface of the fabric during storage, and undergo a complex chemical reaction with nitrogen oxides in the air to form a yellow substance, thereby causing the yellowing of the fabric. Generally speaking, chemical fiber fabrics (such as polyester, nylon, etc.) will add more BHT, which is more prone to phenolic yellowing. [0003] In addition, silicone softe...
