Embodiment Construction

[0012] Nano-resin ball emulsion preparation method A: 20 grams of polystyrene with a Tg of 58° C. and a softening point of 110-120° C. was dissolved in 20 ml of chloroform for later use. Add 200 milliliters of deionized water, 2 grams of sodium dodecylbenzenesulfonate ( DDBS), 1 gram of polyethylene glycol (PEG-4000), 0.5 gram of Span-80 and 0.5 gram of Tween-80, and stir well. Adjust the stirring speed to 5000 rpm, add the polystyrene chloroform solution within half an hour, and stir at 80° C. for 1 hour. Change the condenser tube to distillation mode to remove chloroform, and use vacuum distillation operation to speed up the speed. After the chloroform is determined to be removed, keep the high-speed stirring to cool the temperature to room temperature quickly, and obtain an emulsion of about 100nm polystyrene balls.

Abstract

The invention relates to a method for preparing a nanometer resin ball emulsion. The prepared resin ball emulsion is especially applicable to the manufacturing of a color toner. The method comprises the following steps of: dissolving polymer resin in an organic solvent as few as possible to obtain a resin solution; dissolving a surface active agent accounting for 5-20 w / w% of the polymer resin in a water medium, stirring the solution by using a high shear force vortex and adding the resin solution to obtain an organic liquid droplet emulsion with high dispersibility; and heating and distilling the emulsion to remove the organic solvent to obtain the nanometer resin ball emulsion. The resin content accounts for 10-20 w / w% of total liquid and the particle size of resin balls is 50-300 nm. The nanometer resin ball emulsion has simple method and good quality.

Description

technical field [0001] The invention relates to a preparation method of a resin ball emulsion, and the prepared resin ball emulsion is especially suitable for making color toner. Background technique [0002] Resin ball emulsion is the raw material for manufacturing color toner, accounting for 80-90% of the proportion, and its main function is as a coating agent. The role of the resin is to wrap the stable and dispersed pigment particles and make the colorant adhere to the printing medium to form a firm graphic. The choice of resin depends on the requirements of the fixing process such as temperature and time. At present, there is no preparation method of nano-scale resin ball emulsion. Contents of the invention [0003] In order to overcome the shortcomings of the prior art, the invention provides a preparation method of the nano-resin ball emulsion, which is simple and of good quality. [0004] The invention comprises the following steps: dissolving the polymer resin i...
