Problems solved by technology

[0002] The magnetic roller is one of the parts that have the greatest impact on the blackness of the printing quality. The magnetic roller generally rubs against the powder knife to charge the toner. At the same time, the machine charges the magnetic roller. The frictionally charged toner is adsorbed on the surface of the magnetic roller. It is composed of a magnetic sleeve and a magnetic core. The magnetic sleeve needs to have certain conductivity, wear resistance and roughness. The existing magnetic sleeve has gradually failed to keep up with the rhythm of production and needs to be replaced frequently during production.

Embodiment Construction

[0018] Such as figure 1 Shown, a kind of preparation technology of golden magnetic cover, its manufacture step comprises:

[0019] a, material selection, select a certain proportion of ethanol, xylene, ethylene glycol, phenolic resin, epoxy resin, epoxy curing agent, curing agent, dispersant, graphite, gold powder as the raw material for preparation, wherein the curing agent is p-hydroxybenzene Sulfonic acid;

[0020] b. Mixing, the preparation raw materials are mixed;

[0021] c, spraying, the mixture after the completion of mixing is sprayed on the inner hollow metal tube to make an embryo body;

[0022] d. Baking, putting the sprayed embryo body into an oven to bake and shape.

[0023] In step a, the ratio of the preparation raw materials by weight is 45 parts of ethanol, 30 parts of xylene, 5 parts of ethylene glycol, 30 parts of phenolic resin, 25 parts of epoxy resin, 10 parts of epoxy curing agent, curing agent 2 parts, 1 part of dispersant, 10 parts of graphite, 4 ...

Abstract

The invention discloses a preparation process of a golden magnetic sleeve and a magnetic roller applying the process. The preparation process comprises the steps of performing material selecting; performing material mixing treatment; spraying a metal pipe with a hollow interior with the mixture after material mixing is completed to prepare into a blank body; and finally, putting the completely-sprayed blank body into a drying oven to be subjected to baking and shaping. The magnetic roller comprises the golden magnetic sleeve and a magnetic core; the golden magnetic sleeve is prepared by the above-mentioned steps; and the magnetic core is arranged in the golden magnetic sleeve. Compared with the conventional black magnetic roller, the magnetic roller prepared from the golden magnetic sleevehas more advantages, longer service life and better toner adsorption effect; and in addition, the adsorbed toner can be more uniform on the surface, so that a better printing effect can be realized.

Description

technical field [0001] The invention relates to the field of printing, in particular to a preparation process of a golden magnetic sleeve and a magnetic roller applying the process. Background technique [0002] The magnetic roller is one of the parts that have the greatest impact on the blackness of the printing quality. The magnetic roller generally rubs against the powder knife to charge the toner. At the same time, the machine charges the magnetic roller. The frictionally charged toner is adsorbed on the surface of the magnetic roller. It is composed of a magnetic sleeve and a magnetic core. The magnetic sleeve needs to have certain conductivity, wear resistance and roughness. The existing magnetic sleeve has gradually failed to keep up with the pace of production and needs to be replaced frequently during production. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the object of the present invention is to provide a preparat...
