Abstract
The invention relates to a composite material and a method for manufacturing disengaging pawls for copiers and printers. Currently, the global disengaging pawl demand is large, due to the problems such as raw material formula and machining process of disengaging pawls, disengaging pawls are easy to damage, and over 30% of copier and printer faults is caused by the damage and badness of disengaging pawls, thereby bringing troubles to copier and printer manufacturers. The composite material is characterized by being composed of modified polyether ketone, silicon carbide, boron nitride, graphite, glass fiber and ceramic powder, wherein the modified polyether ketone contains 30% of carbon fiber. According to the invention, the modified polyether ketone (PEK) which is low in cost is adopted for replacing polybenzimidazole, so that the main raw material cost is reduced by 80%. A process for manufacturing disengaging pawls is simplified.
Description
Technical field
The present invention relates to and a kind ofly manufacture duplicating machine, the matrix material of printer disengaging pawl and method.
Background technology
Duplicating machine is in transfer process, copy paper is due to the adsorption of electrostatic, tightly be attached in photosensitive drums, disengaging pawl effect is exactly stripped down from photosensitive drums by the copy paper be attached in photosensitive drums tightly, especially be easily out of shape after the high temperature of the fixing hot-rolling of paper is fixing at fixing position paper, need disengaging pawl to help to separate, otherwise will the situation of paperboard be there will be.The demand of current global disengaging pawl is larger, due to the problem such as formula for raw stock, complete processing of disengaging pawl, disengaging pawl ratio is easier to damage, due to disengaging pawl damage or bad reason account for duplicating machine, printer fault more than 30%, for duplicating machine and printer manufacturer and client bring worry.
Poly-stupid and current engineering plastics being considered to highest level of imidazoles (PBI) are also the main raw material(s)s manufacturing duplicating machine disengaging pawl.Can work under 310 DEG C of conditions for a long time, tolerable temperature can reach 760 DEG C instantaneously.Under-160 DEG C of conditions, keep its properties to stablize.Poly-stupid and imidazoles (PBI) corrosion resistance is very strong, in acid or alkali environment, retention is stablized.Twice, the hardness of the Pespel product that intensity is are 50% of glass, and ash content also can be controlled in below 2ppm.
Current China relevant enterprise uses poly-stupid and imidazoles (PBI) as the main raw of duplicating machine, printer disengaging pawl mostly.But this material require solidifies 36 hours under 380 DEG C of conditions, die temperature will reach 260 DEG C, the temperature of plasticizing will reach 420 DEG C-450 DEG C, requires higher to production mould and processing condition.The unit price of this material is also higher, can reach 1800.00/kg.
Summary of the invention
The present invention is directed to the defect that prior art exists, provide a kind of and manufacture duplicating machine, the matrix material of printer disengaging pawl and method, simplify production craft step, reduce manufacturing condition, reduce raw-material cost, improve enterprise's productivity effect.
For this reason, the present invention takes following technical scheme, manufacture a matrix material for duplicating machine, printer disengaging pawl, it is characterized in that described matrix material is made up of modified polyether ketone and silicon carbide, boron nitride, graphite, glass and ceramics powder, described modified polyether ketone is containing 30% carbon fiber.
The accounting of described modified polyether ketone, silicon carbide, boron nitride, glass, ceramics powder is respectively 70%, 12%, 5%, 5%, 8%.
Utilize above-mentioned matrix material to manufacture the method for duplicating machine and printer disengaging pawl, it is characterized in that matrix material being put into the mould that temperature is 180-200 DEG C, adopt 380-400 DEG C to plastify afterwards again.
As preferably, the temperature of described mould is 200 DEG C.
The present invention uses modified polyether ketone (PEK) and silicon carbide, boron nitride, graphite, glass, ceramics powder to form a kind of matrix material becomes the main raw material(s) manufacturing duplicating machine disengaging pawl.And have in technique need not solidify, die temperature is low, plasticization temperature is low, product cost is low feature, feature that product cost is low.Product physicochemical property all reaches or is better than using duplicating machine, the printer disengaging pawl that poly-stupid and imidazoles (PBI) manufactures as main raw.
The present invention mainly has following effect:
1. product formula for raw stock of the present invention, use the lower modified polyether ketone (PEK) of price to substitute poly-stupid and imidazoles (PBI), main raw material cost reduces 80%.Simplify disengaging pawl manufacturing process.
2. reduce the requirement to the working conditions such as mould and working condition in production process, shorten products production process period, thus improve production efficiency more than 20%.
3., owing to eliminating the technological temperature in curing process and the course of processing, greatly reduce the energy consumption in production process.
4. the present invention make duplicating machine disengaging pawl for a long time at 210 DEG C-230 DEG C until indeformable under 260 hot conditionss.And improve product surface smooth degree.
Embodiment
Below in conjunction with specific embodiment, set forth the present invention further.
The present invention discloses a kind of matrix material manufacturing duplicating machine, printer disengaging pawl, and matrix material is made up of modified polyether ketone and silicon carbide, boron nitride, graphite, glass and ceramics powder, and modified polyether ketone is containing 30% carbon fiber.
In matrix material the accounting of modified polyether ketone, silicon carbide, boron nitride, glass, ceramics powder be respectively 70%, 12%, 5%, 5%, 8%.
Utilize above-mentioned matrix material to manufacture the method for duplicating machine and printer disengaging pawl, it is characterized in that matrix material being put into the mould that temperature is 180-200 DEG C, adopt 380-400 DEG C to plastify afterwards again.
As preferably, the temperature of described mould is 200 DEG C.
Polyetherketone (PEK) is also can by aromatic series dihalo thing and 4 by a class special engineering plastics of the stupid ketone of difluoro two and aromatic dicarboxylic phenol high-temperature polycondensation, and the polycondensation of 4 '-dihydroxy benaophenonel becomes and generally has high thermo-oxidative stability, high mechanical property.Belong to special engineering plastics.This polyaryletherketone fusing point is 334 DEG C, tensile strength 112-132Mpa, 1.1Gpa during tensile modulus 150 DEG C, is 0.4Gpa when 180 DEG C.Strongthener or matrix material can be made with glass fibre or carbon fiber.Be applied to high-temperature-resistant structure material, special material, high-abrasive material and electrically insulating material.The mechanical property of this matrix material and thermotolerance are all higher than matrix material.Compared with clean polyether ketone resin, the tensile strength containing the modified polyether ketone matrix material of 30% carbon fiber improves 1 times, and flexural strength improves 3 times, and shock strength is substantially constant.
The modified polyether ketone (PEK) that the present invention have employed use 70% in formula for a product substitutes poly-stupid and imidazoles (PBI).Add silicon carbide 12%, boron nitride 5%, glass 5%, ceramics powder 8%.In process for making, deducted starting material high temperature curing process, die temperature is reduced to 200 DEG C by 260 DEG C, plasticization temperature reduces to 380 DEG C-400 DEG C by 420-450.Shorten more than 36 hours complete processing time, mainly eliminate curing process.
