Abstract

The invention discloses a multifunctional organic silicon finishing agent and a preparation method thereof. The multifunctional organic silicon finishing agent comprises the following components in percentage by mass: anti-ultraviolet polyether organic silicon oil, isobutyl alcohol, composite emulsifier of phosphate betaine type gemini surfactant and fatty alcohol-polyoxyethylene ether in a ratio of 1:1, pH buffering agent and deionized water. The preparation method for the multifunctional organic silicon finishing agent comprises the following steps of: modifying organic silicon by adopting a special heterocyclic hindered ammonia compound, substituting the conventional amino, introducing a polyether functional unit on the main chain of the organic silicon, introducing the hindered ammonia compound on the branched chain, and synthesizing multifunctional organic silicon oil. The finishing agent keeps the original advantages of the amino silicon oil, and is particularly suitable for soft finishing and anti-ultraviolet finishing of bleached fabrics and light color fabrics; and the finishing agent can be prepared into silicon oil micro-emulsion of various proper concentrations by full emulsifying and has strong usability.

Description

technical field [0001] The invention relates to a multifunctional organosilicon finishing agent and a preparation method thereof. Background technique [0002] Silicone emulsion is an important finishing agent in the process of fabric treatment. It can significantly improve the hand feel of fabrics, making them smooth and soft. In recent years, there are more fabric softening and smoothing agents based on amino silicone oil on the market. At present, there are relatively few developments on the comprehensive functions of silicone finishing agents such as anti-ultraviolet, anti-yellowing, soft and smooth. Contents of the invention [0003] Purpose of the invention: In order to solve the deficiencies of the prior art, the present invention provides a multifunctional silicone finishing agent with anti-ultraviolet and anti-yellowing functions. [0004] Another object of the present invention is to provide a method for preparing the above-mentioned multifunctional silicone fi...
