Abstract
The invention discloses a developing magnetic roller coating, aiming at providing a developing magnetic roller coating which is good in matching performance, less in influence by environment factors, good in wear resistance and high in product first-pass yield. The developing magnetic roller coating comprises the following components in parts by mass: 59-111 parts of resin I, 53-97 parts of graphite, 18-32 parts of kaolin or titanium dioxide, 22-40 parts of PMMA (Polymethyl Methacrylate) powder, 70-130 parts of ethanol, 196-364 parts of xylene, 210-390 parts of glass beads, and 42-78 parts of curing agent. The developing magnetic roller coating can be applied to field of regenerative technology for recycling developing rollers.
Description
Technical field
The present invention relates to a kind of regeneration techniques that reclaims developing magnetic roll, relate in particular to a kind of coating for regeneration developing magnetic roll.
Background technology
Produce in consumptive material industry in regeneration, the developing magnetic roll of toner cartridge is vital parts, and its quality good or not directly affects the print quality (as blackness, bottom ash, life-span etc.) of product.At present normal sandblast or the anodized treatment process of adopting used developing magnetic roll regeneration, and this method has a fatal shortcoming, and bottom ash, appears in the as easy as rolling off a log impact that is subject to environment in the time of high temperature, occurs look light and bottom ash problem in the time of low temperature simultaneously.The processing mode that some enterprise also adopts surface to spray is used developing magnetic roll regeneration, but the coating of spraying has following shortcoming at present: 1, match and need to coordinate with specific powder and photosensitive drums, just can reach client required; 2,, while application in high page output or high-speed printer, its wear resistance is inadequate; 3,, because of coating technology problem, production qualification rate is low.Also have in addition some enterprises, the magnetic roller that does not reach requirement is directly scrapped to processing, no longer regeneration, thus cause larger waste.
Summary of the invention
Technical problem to be solved by this invention is to overcome the deficiencies in the prior art, aims to provide a kind ofly to have good matched performance, be subject to that such environmental effects is little, wear resisting property good and produce the high developing magnetic roll coating of first-pass yield.
The technical solution adopted in the present invention is: calculate according to the mass fraction, the present invention includes following component:
59～111 parts of epoxy resin;
53～97 parts, graphite;
18～32 parts of kaolin or titanium dioxides;
22～40 parts, PMMA powder;
70～130 parts of ethanol;
196～364 parts of dimethylbenzene;
210～390 parts of granulated glass spherees;
42～78 parts, solidifying agent.
Preferably, calculate according to the mass fraction, the present invention also comprises following component: 7～13 parts of carbon blacks.
Preferably, calculate according to the mass fraction, the present invention also comprises following component: 32～60 parts, fourth fat.
Preferably, calculate according to the mass fraction, the present invention also comprises following component: 56～104 parts, resol.
Preferably, the present invention is 8～15 μ m at the thickness of developing magnetic roll.
The invention has the beneficial effects as follows: because the present invention calculates according to the mass fraction, comprise following component: 159～111 parts of resins; 53～97 parts, graphite; 18～32 parts of kaolin or titanium dioxides; 22～40 parts, PMMA powder; 70～130 parts of ethanol; 196～364 parts of dimethylbenzene; 210～390 parts of granulated glass spherees; 2 42～78 parts of resins, so, the present invention has good matched performance, be subject to that such environmental effects is little, wear resisting property good, in the process using, the consumption of carbon dust is less than thousand pages of 45g/, produce first-pass yield up to 90-95%, and developing magnetic roll treatment technology in the process of regeneration is succinct, the circle after developing magnetic roll regeneration is beated and is less than 0.05mm.
