Embodiment 1

[0051] Put 100 parts of xylene into the reaction kettle, then blow it with nitrogen, replace all the air in the kettle, gradually raise the temperature to 138°C, and drop the mixed solution in the state of xylene reflux (the composition of the mixed solution is 60 parts of styrene , 12 parts of butyl methacrylate, 12 parts of hexyl acrylate, 6 parts of acrylic acid, 5 parts of ethylene glycol, 0.6 parts of initiator, 0.3 parts of crosslinking agent, 0.1 part of catalyst), added dropwise for 5 hours. Take 1,17 parts of wax-modified crystalline polyester, melt it at a temperature higher than its melting point, then add it dropwise to the reaction system, keep it warm for 3 hours, carry out vacuum extraction to a negative pressure of 0.08MPa, and keep it empty for 2 hours , pressurize and discharge with nitrogen. Cool to room temperature, pulverize, finely powder, and sieve to obtain binder composition 1.

Embodiment 2

[0053] Put 200 parts of xylene into the reaction kettle, then blow it with nitrogen, replace all the air in the kettle, gradually raise the temperature to 138°C, and drop the mixed solution in the state of xylene reflux (the composition of the mixed solution is 65 parts of styrene , 8 parts of butyl methacrylate, 9 parts of hexyl acrylate, 10 parts of acrylic acid, 8 parts of ethylene glycol, 0.3 parts of initiator, 0.6 parts of crosslinking agent, 0.1 part of catalyst), added dropwise for 5 hours. Take 2,10 parts of wax-modified crystalline polyester, melt it at a temperature higher than its melting point, then add it dropwise to the reaction system, keep it warm for 3 hours, carry out vacuum extraction to a negative pressure of 0.08MPa, and keep it empty for 2 hours , pressurize and discharge with nitrogen. Cool to room temperature, pulverize, finely powder, and sieve to obtain binder composition 2.

Embodiment 3

[0055] Put 300 parts of xylene into the reaction kettle, then blow it with nitrogen, replace all the air in the kettle, gradually raise the temperature to 138°C, and drop the mixed solution in the state of xylene reflux (the composition of the mixed solution is 55 parts of styrene , 10 parts of butyl methacrylate, 10 parts of hexyl acrylate, 10 parts of acrylic acid, 10 parts of ethylene glycol, 0.5 parts of initiator, 0.4 parts of crosslinking agent, 0.1 part of catalyst), added dropwise for 5 hours. Take 3 or 7 parts of wax-modified crystalline polyester, melt it at a temperature higher than its melting point, then add it dropwise to the reaction system, keep it warm for 3 hours, carry out vacuum extraction to a negative pressure of 0.08MPa, and keep it empty for 2 hours , pressurize and discharge with nitrogen. Cool to room temperature, pulverize, finely powder, and sieve to obtain binder composition 3.

Abstract

The invention discloses an adhesive composition for ink powder for printers and copying machines. The composition is prepared from 85-99% by mass of mixed liquid and 1-15% by mass of wax-modified crystalline polyester, wherein the mixed liquid is mainly prepared from styrene, butyl methacrylate, crylic acid hexyl, crylic acid and ethylene glycol monomers. The invention further discloses a preparation method of the adhesive composition for the ink powder for the printers and the copying machines. The adhesive composition disclosed by the invention is added into the ink powder applied to electromagnetic induction heating devices, so that the ink powder has excellent low-temperature fixation property, high-temperature anti-excursion property and storability.

Description

technical field [0001] The invention relates to a binder composition for toner and a preparation method thereof, in particular to a binder composition for toner suitable for electromagnetic induction heating fixing method and a preparation method thereof. Background technique [0002] In recent years, with the rapid development of information technology, the degree of office automation is getting higher and higher, the use of copiers and printers is becoming more and more extensive, and the requirements for the performance of copiers and printers are also getting higher and higher. Generally speaking, the working process of copiers and printers is to first form an electrostatic latent image on the photoreceptor, then absorb toner to develop it, transfer the image to paper, and use hot-press fixing. In order to shorten the warm-up time of the printer and increase the printing speed, the heating components in the thermal fixing process are also gradually improved and updated, ...
