Problems solved by technology

The main raw materials of this polymer resin are styrene and butyl acrylate, and the content of styrene is relatively high, and the content of butyl acrylate is low. Therefore, its glass softening temperature and softening point temperature are high. The color laser printer toner produced has poor chroma, insoluble, poor fixation, low firmness, and the printed graphics and texts are not clear and have poor layers.
In addition, the color laser printer toner produced with this resin as a raw material requires a high fixing temperature. If the fixing temperature is high, it not only consumes more power, but also has high production costs, and is prone to generate ozone, which is not conducive to environmental protection.

Embodiment Construction

[0027] first embodiment

[0028] Get the styrene of 70 parts by weight, the butyl acrylate of 15 parts by weight, the butyl methacrylate of 0.5 parts by weight, the dibutyl maleate of 1 part by weight, the benzoyl peroxide of 6 parts by weight, the benzoyl peroxide of 0.2 parts by weight divinylbenzene, 0.2 parts by weight of α-methylstyrene linear dimer, 4 parts by weight of bone glue and 4 parts by weight of starch.

[0029] Put styrene, butyl acrylate, butyl methacrylate, and dibutyl maleate into the high-level tank first, and after stirring for 15 minutes, add divinylbenzene, benzoyl peroxide, and α-methylstyrene Linear dimer, continue to stir until uniform, and make mixture A;

[0030] According to the weight ratio of bone glue: boiling water = 1:25, add boiling water to the bone glue and stir evenly to obtain the release agent E; at the same time, according to the weight ratio of starch: deionized water = 1:25, add deionized water to the starch water, stirred evenly to...

Abstract

The invention discloses a macromolecule resins to be used for color laser printer carbon powder and the preparation method of the macromolecule resins. The macromolecule resins is made of a proportion of cinnamene, butyl acrylate, butyl methacrylate, dibutyl maleate, benzoperoxide, divinylbenzene, dipoly-alpha-methylstyrene, bone glue and amylum via the procedures such as mixing, rinsing, drying, smashing and sheltering. The color laser printer carbon powder to be produced with the resins as the main raw materials has is good in coloring, high in firmness, clear in the printed text and good in arrangement, which is also low in the production cost and beneficial to the environment protection. and does not produce ozone.

Description

technical field [0001] The invention relates to a main raw material for producing color laser printer toner—macromolecule resin and a preparation method thereof. Background technique [0002] Polymer resin is the main raw material for the production of toner for color laser printers. At present, the polymer resins used in the production of color laser printer toner are all made by solution method. The main raw materials of this polymer resin are styrene and butyl acrylate, and the content of styrene is relatively high, and the content of butyl acrylate is low. Therefore, its glass softening temperature and softening point temperature are high. The color laser printer toner produced has poor chroma, insoluble, poor fixation, and low firmness, and the printed graphics and texts are not clear and have poor layers. In addition, the color laser printer toner produced with this resin as a raw material requires a high fixing temperature. If the fixing temperature is high, it not ...
