Abstract

The invention relates to a hyperbranched polymer, hyperbranched polymer modified organic silicone oil and application of the organic silicone oil. According to the invention, the hyperbranched polymer is mainly obtained through the reaction of polyol, acrylate and amine compounds; and hydrogen-containing silicone oil is modified with the hyperbranched polymer, allyl polyether and allyl glycidyl ether which are used as modifying agents, and the obtained modified silicone oil can well disperse an organic pigment with a low-polar surface or polar-free surface.

Description

technical field [0001] The present invention relates to a kind of hyperbranched polymer and its modification and application; Specifically, relate to a kind of hyperbranched copolymer, and the silicone oil (also known as silicone oil) modified by said hyperbranched copolymer and its use. Background technique [0002] Organic pigments have been widely used in many industrial fields due to their advantages such as complete color spectrum, high tinting strength, bright color and simple application. As a colorant, organic pigments can only exert their coloring effect if they are uniformly and stably dispersed in the medium. Therefore, before use, physical or chemical methods must be adopted to miniaturize the pigment particles and control them within the required particle size range to achieve the purpose of stable dispersion. At present, inorganic dispersants, surfactants, and polymer dispersants are commonly used to modify the surface of organic pigments to achieve the purpo...
