Abstract

The invention relates to the technical field of printing and dyeing auxiliaries, in particular to an organosilicon darkening finishing agent and a preparation method thereof. The organosilicon darkening finishing agent provided by the invention comprises the following components in percentages by mass: 15% to 25% of butyl acrylate, 13% to 26% of a modifier, 0.1% to 0.3% of a catalyst, 3% to 6% ofa compound emulsifier and 60% to 75% of deionized water. The organosilicon darkening finishing agent provided by the invention can darken the color of a treated fabric, is remarkable in darkening effect and high in stability, is not prone to cause a demulsification phenomenon in an application process, and cannot cause the problems of roller sticking, silicon spots and the like.

Description

technical field [0001] The invention relates to the technical field of printing and dyeing auxiliaries, in particular to an organosilicon darkening finishing agent and a preparation method thereof. Background technique [0002] In recent years, due to the country's strengthening of environmental protection, the price of dyes has risen sharply, and the cost of dark sewage treatment is high. Using additives and surface treatment to change the surface characteristics of fibers and minimizing the amount of reflected light of fibers is to improve their apparent dark effect and reduce dyes. effective method of dosage. [0003] The dyed fabric is treated with a low refractive index silicone darkening agent, and baked to form a film to reduce the amount of reflected light on the surface, so that the fabric can achieve a deep color effect. Many studies have used octamethylpolysiloxane and special amino coupling agents for emulsion polymerization to obtain silicone products that are ...
