Abstract

The invention discloses a preparation method of amino resin microspheres. The preparation method comprises the following steps: step 1, dispersing silicon dioxide particles into an ethanol solution under an ultrasonic oscillation condition to obtain a silicon dioxide dispersion liquid, wherein the volume fraction of the ethanol solution is 60%-75%, and the mass of the ethanol solution is 5-10 times the mass of the silicon dioxide particles; step 2, mixing amino resin, diethyl carbonate, fumaric acid, ethyl acetate and organic silicon, adding a cationic surface active agent under stirring at a temperature of 60-90 DEG C, and continuing stirring for 40-60 minutes after the cationic surface active agent is added so as to obtain a mixed system; step 3, adding the silicon dioxide dispersion liquid into the mixed system obtained in the step 2, and carrying out ultrasonic dispersion for 40-60 minutes at a temperature of 80-90 DEG C to obtain slurry; and step 4, grinding the slurry obtained in the step 3 through a colloid mill to obtain the amino resin microspheres.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a preparation method of amino resin microspheres. Background technique [0002] As a common coloring product, printing ink is mainly composed of raw materials, connecting substrates and filling components. It has a certain fluidity, is in the form of paste, and has a certain viscosity. The color, printing adaptability and drying speed of the ink have a significant impact on the printing effect of the ink, which puts forward specific requirements for the ink's water resistance, light resistance, and acid and alkali resistance. With the rapid development of the concept of energy saving and environmental protection, the development of ink is bound to develop in the direction of low toxicity, quick drying, bright luster and stability. Most of the existing printing inks have defects such as insufficient viscosity and insufficient environmental protection, result...
