Embodiment 1

[0067] Embodiment 1 A kind of color developing roller

[0068] This embodiment provides a color developing roller, which includes an iron shaft (1215 free-cutting iron material), a conductive foam rubber sleeve attached to the outside of the metal shaft, and a conductive dense rubber film sleeve attached to the outside of the conductive foam rubber; Wherein, the conductive dense rubber membrane sleeve and the conductive foam rubber are integrally formed.

[0069] Wherein, the conductive foam rubber is prepared by mixing the A-section material and the B-section material at a weight ratio of 100:10; the ingredients list is as follows (parts by weight):

[0070] Table 1. Contents of each component in the ingredient list of section A material

[0071]

[0072] The active agent is prepared from the following components in parts by weight: zinc oxide (1.6 parts), polyethylene glycol (0.44 parts) and stearic acid (0.44 parts).

[0073] Table 2. Contents of each component in the ...

Embodiment 2

[0079] Embodiment 2 A kind of color developing roller

[0080] This embodiment provides a color developing roller, which differs from Embodiment 1 in that:

[0081] Table 3, each component content (parts by weight) of the batching list of the A section material

[0082]

[0083] Table 4, each component content (parts by weight) of the batching table of the B section material

[0084]

[0085] The modified foaming agent is prepared from the following components by weight: baking soda (1 part), foaming agent AC-2000 (1 part), alum (0.7 part), and urea (0.8 part);

[0086] The accelerator is made of the following components by weight: accelerator EZ (0.5 part), accelerator BZ (0.45 part) and accelerator TT (0.5 part);

[0087] Compared with Example 1, the color developing roller described in this embodiment has a faster vulcanization speed, more sufficient vulcanization, and more foaming agent can reduce the density and hardness of the rubber material, so as to achieve a ...

Embodiment 3

[0088] Embodiment 3 A kind of preparation method of color developing roller

[0089] The present invention also provides the preparation method of the color developing roller described in embodiment 1, comprising the following steps (its production flow chart is as follows: figure 1 ):

[0090] (1) Preparation of conductive foam rubber: A-stage material is compounded and extruded with the metal shaft after banburying and kneading, so as to form conductive foam rubber outside the metal shaft;

[0091] (2) Vulcanization molding: cut off the excess conductive foam rubber on the metal shaft, put the conductive dense rubber film sleeve on the outside of the conductive foam rubber, put the whole into the mold, and carry out vulcanization molding to obtain a color developing roller;

Abstract

The invention relates to a color development roller and a method for manufacturing the same. The color development roller comprises a metal axes, conductive foam rubber and a conductive dense rubber membrane sleeve. The conductive foam rubber is attached to the outside of the metal axes in a sleeving manner, and the conductive dense rubber membrane sleeve is attached to the outside of the conductive foam rubber in a sleeving manner; the conductive dense rubber membrane sleeve and the conductive foam rubber are integrally formed. The color development roller and the method have the advantages that the color development roller is good in resilience and printing quality, high in abrasion resistance and low in cost, and identical requirements on the hardness of original rubber-covered rollers can be met by the color development roller; the method is free of spraying links, excellent printing effects can be realized if the surfaces of the color development roller are slightly carbonized only under UV (ultraviolet) light illumination conditions, and accordingly environmental pollution and injury on staffs due to spraying can be prevented.

Description

technical field [0001] The invention relates to a color developing roller suitable for the fields of printers, copiers and facsimile machines and a preparation method thereof, belonging to the technical field of electrostatic latent images. Background technique [0002] Developing rollers are widely used in the fields of printers and copiers. The charging roller charges and exposes the photosensitive drum to form an electrostatic latent image, and then transfers the toner to the electrostatic latent image on the photosensitive drum through the developing roller, and the toner latent image is sent to the paper for heating and shaping to form a final printed text image. [0003] The existing developing roller usually consists of an iron shaft core and a dense conductive rubber sheathed on the outside of the iron shaft core. Since the rubber layer outside the iron shaft is hard rubber, in order to improve the printing effect, it is necessary to carry out a spraying process aft...
