Abstract

The invention relates to a preparation method of color polyacrylate polymer microspheres and belongs to the technical field of functional polymer microsphere preparation. According to the preparation method, firstly, functional dye with double-bond functional groups is synthesized, then, the dye, polyacrylate monomers, dispersion stabilizers and initiating agents are used as raw materials, and the color polyacrylate polymer microspheres are prepared in alcohol. The grain size of the color microspheres is 1 to 10mum, the grain size is uniform, and the color microspheres meeting the application requirement can be prepared under the condition of low dye consumption. The color polyacrylate polymer microspheres are used for powdered ink of a laser printer, the coloring of paint, plastic, rubber and fiber, the dye shift prevention and toughening.

Description

technical field [0001] The invention discloses a method for preparing colored polyacrylate polymer microspheres, which belongs to the technical field of functional polymer microsphere preparation. Background technique [0002] Dispersion polymerization is a better method for preparing monodisperse microspheres of 1-10 μm. As a functional polymer material, it has a wide range of uses in the fields of analytical chemistry, biochemistry, immunomedicine, and standard metrology, especially in some high-tech fields (such as information memory, drugs, and catalyst carriers, etc.). Resin-like research has been paid more and more attention. At present, the particle size control of microspheres, surface functionalization, special morphology microspheres and functional microspheres are the focus of our research. However, there are few scientific researchers who have studied the preparation of microspheres with uniform particle size and different colors, and there are few products on ...
