Problems solved by technology

And because xylene is used as a solvent, the production cost is higher
Secondly, because this production method uses electric heating in the reaction process, and the heating temperature is relatively high (up to 250-280°C), if you are not careful, the xylene gas w

Abstract

A high-molecular resin used for ink powder of copier is prepared from styrene, butyl acrylate, divinylbenzene, dibenzoyl peroxide, edible gelatin and edible starch through proportional mixing, reaction, washing, dewatering, drying and sieving. Its advantages are no toxicity, low cost, and no pollution of environment.

Description

technical field [0001] The invention relates to a main raw material for making toner for electrostatic copiers-macromolecule resin and a preparation method thereof Background technique [0002] Polymer resin is the main raw material for the production of toner for electrostatic copiers. At present, the solution method is commonly used to synthesize the bonding resin. The polymer resin produced by the solution method, its main raw material is styrene --- butyl acrylate --- butyl maleate ternary copolymerization, and the solvent used is xylene. Its preparation method is to adopt electric heating, react in two reactors in the front and back, and finally vacuumize and solidify. Although the polymer resin produced by the above-mentioned raw materials and methods can be used as the raw material of electrostatic copier toner, due to the use of xylene as a solvent, the resin produced will inevitably have xylene residues. Toner made from this resin and magnetic powder with xylene ...
