Adhesive composition for printing powdered ink and preparation method thereof

Abstract

The invention discloses an adhesive composition for printing powdered ink and a preparation method thereof. The adhesive composition is prepared from the following raw materials in parts by weight: 40-60 parts of styrene, 8-12 parts of methyl methacrylate, 5-10 parts of triisopropanolamine cyclic borate, 5-10 parts of acrylic acid, 4-8 parts of ethylene glycol, 0.2-0.6 part of initiator, 0.3-0.7 part of a crosslinking agent, 0.1-0.3 part of a catalyst, 10-15 parts of a catalyst, 10-15 parts of colloidal graphite powder, 7-9 parts of gaseous silicon dioxide, 10-20 parts of wax modified crystalline polyester, 0.1-0.3 part of a chain transfer agent, 0.5-0.9 part of halohydrocarbon, 0.2-0.4 part of pH buffer agent and 3-5 parts of flocculant. The adhesive composition has excellent low-temperature fixing performance, high temperature deviation and excellent storage, can be quickly molten when being heated at relatively low temperature, keeps relatively small viscosity change in a relatively wide temperature range and has relatively high melt strength and quick solidifying when being separated from a fixing roller, can be widely applied to various printers and copiers, and can be sufficiently adaptive to the increasing requirement for high speed and low temperature fixing and the like of electromagnetic inductive heating equipment.

Description

technical field [0001] The invention relates to the technical field of printing supplies, in particular to an adhesive composition for printing toner 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, and the lamp heating form, ceramic heating form, electromagnetic inducti...

Problems solved by technology

[0005] However, the performance of the binder composition as the main component of the toner plays a leading role in the performance of the toner. The existing binder composition can satisfy good low-temperature fixability, but at the same time, the offset resistance and storage performance are limited. a certain degree of reduction
