Rubber material and manufacturing process for rubber roller applied to engineering printer/copier

Abstract

The invention provides a rubber material for a rubber roller applied to an engineering printer / copier. The rubber material comprises the following raw materials in parts by weight: 100 parts of ethylene propylene diene monomer rubber, 10-40 parts of liquid ethylene propylene diene monomer T77, 5-15 parts of activated zinc oxide, 2-4 parts of magnesium oxide, 1-3 parts of an anti-aging agent 4010,1-2 parts of an anti-aging agent MB, 15-40 parts of naphthenic oil, 15-40 parts of carbon black N330, 30-50 parts of conductive carbon black, 10-20 parts of an antistatic agent, 1-3 parts of an accelerant M, 0.5-2 parts of an accelerant DM and 2-6 parts of sulfur. The invention further provides a manufacturing process for the rubber roller applied-the engineering printer / copier. The produced rubber material is high in quality; and the novel manufacturing process conforms to the environmental protection concept of the current society, is low in production cost, effectively improves extension efficiency, reduces pollution to the environment and achieves the purposes of energy conservation and environmental protection.

Description

technical field [0001] The invention relates to the field of engineering printers / copiers, in particular to a rubber material and a manufacturing process for rubber rollers used in engineering printers / copiers. Background technique [0002] Engineering printers are for large format paper or drawings. Some large industrial and mining enterprises and design institutes need to use engineering printers to print large-format design drawings; construction units of real estate companies copy blueprints; graphic shops use engineering copiers to copy drawings for customers, etc. [0003] The engineering printer is a complex and precise mechanical and electronic device. The rubber roller is the main part of the printer (including feed roller, conveying roller, balance roller, pressure roller, metering roller, fixing roller, folding roller), which affects the printing quality and paper quality. transport plays a key role. Due to the problem of the rubber roller, the following failure...

AI Technical Summary

Problems solved by technology

[0004] 1. The left and right, top and bottom irregular shades of the output proofs may be caused by the color fading or contamination of the transfer roller

[0005] 2. The image and text of the output sample sheet are regularly different in depth, the possible reason: poor contact of the electrode of the charging and transfer roller

[0006] 3. There are regular white spots in the longitudinal direction of the sample sheet. The cause of the failure: the surface of the charging roller and the fixing roller is partially damaged.

[0007] 4. There are regular black spots (spots) in the longitudinal direction of the sample sheet. Possible cause of failure: the ionization film of the charging roller is damaged or the surface of the fixing roller is damaged.

[0008] 5. Irregular black lines appear vertically or horizontally on the page. Possible cause of failure: scratches on the surface of the fixing roller

[0009] 6. The possible cause of the pollution on the back of the printing paper: the color of the pressure rubber roller is faded or contaminated

[0010] 7. Secondary complex images appear in the vertical direction of the page. Possible cause of failure: the surface of the heating roller is worn

[0011] At present, there are generally two production methods for engineering printing / copier rubber rollers. One production method is injection molding. After vulcanization, the rubber at the non-adhesive part is turned on a lathe according to the drawing requirements. This is a waste of rubber material, and it is labor-intensive and time-consuming , another production method is the sleeve type, which is to make the rubber material into a rubber sleeve and put it on the metal core. The rubber roller in this way is easy to cover and not fasten, and slipping occurs, which affects the quality of printed products.

[0012] To sum up, there are two major defects in the rubber rollers of existing engineering printing / copier machines. One is the lack of high-quality rubber materials for rubber rollers, and the other is that there is no economical and energy-saving production process.
