Core-shell type (meth)acrylate copolymer particle emulsion and its preparation method and fabric deepening agent composition

Abstract

The invention discloses a core-shell type (meth)acrylate copolymer particle emulsion, a preparation method thereof and a fabric darkening agent composition. The copolymer particles include: a) a core, which contains 5-40% by weight C 2－4 (Meth)acrylate copolymers of alkenyl polyoxyalkylene ether copolymerized units, based on the total weight of all copolymerized units in the core, b) a shell layer containing 3-8% by weight of C 2－4 Alkenyl siloxane modified nano silica copolymer unit, 10-20 wt% C 2－4 Alkenyl polysiloxane copolymerized units and 5-20% by weight C 2－4 A (meth)acrylate copolymer of alkenyl polyoxyalkylene ether copolymerization units, based on the total weight of all copolymerization units in the shell, wherein the weight ratio of the core to the shell is 1:1-1:3, and the core The average particle diameter of the shell-type (meth)acrylate copolymer particles is 50-300 nm. The polymer has stable polymerization reaction, high yield, uniform and stable emulsion particle size, and can be used as a fabric darkening agent with excellent effect and good fabric hand feeling.

Description

Core-shell type (meth)acrylate copolymer particle emulsion and its preparation method and fabric Deepening agent composition technical field The present invention relates to a kind of inorganic-organosilicon co-modified (meth)acrylate copolymer and preparation method thereof and application thereof use. Specifically, the present invention relates to a core-shell type (meth)acrylate copolymer particle emulsion, a preparation method thereof, and a particle emulsion containing the same. fabric darkening agent composition. Background technique [0002] With the vigorous rectification of the printing and dyeing industry by the state in recent years, energy saving and emission reduction, transformation to technology, and improving product competitiveness become an urgent task for the industry. At the same time, the promotion of new microfiber fabrics and the Arab region's response to absolute black Pursuit, making the fabric dye depth problem has been paid more and more ...

Problems solved by technology

[0004] The darkening of light and light fabrics, especially chiffon fabrics, has always been a difficult point in the industry. Usually, two darkening processes are required. First, dipping acrylic resin darkening agent and then dipping silicone can obtain the desired darkening effect. Two processing steps are used to increase the depth. Increased processing difficulty, but also increased energy consumption
