Description
Technical field
The invention belongs to intaglio printing field, more particularly to one kind of multiple nonmetallic compound gravure printing rollers and its preparation side
Method.
Background technology
The one kind of intaglio printing as four big mode of printings, it is abundant with its printing product layer of ink, it is bright-colored, saturation degree is high,
The advantages that printing plate press resistance rate is high, print quality is stable, print speed printing speed is fast occupies extremely in printing packaging and picture and text publishing area
Consequence.It as the saying goes, print quality " three points are being printed, and seven points by plate-making ".In gravure equipment, the position of most critical
It is exactly gravure printing roller.The pattern for needing to print is carved on the copper coating of gravure printing roller, and during printing, the ink in ink fountain is filled out
It is charged in the pit of gravure printing roller, the ink on roller surface is wiped off with doctor, and contained ink passes through impression cylinder in pit
Pressurization is imprinted directly on stock, obtains required pattern.The gravure printing roller used at present is made generally by 4 layers of metal material
Material composition (being followed successively by steel, nickel, copper, chromium from inside to outside), the problems such as processed complex, product weight weight, environmental pollution be present.
The material of the base roller of gravure printing roller is generally seamless steel pipe, in order to reach mechanical precision requirement, so the wall of steel pipe
Thickness is from 10mm to 30mm, and large scale roller is then thicker, so weight is heavier.
The last chromium plating process of roll body be in order to prevent sculptured surface layers of copper to be hindered by doctor, but during electrodeposited chromium will
It is largely big using chemicals, waste water and exhaust emissions such as strong acid, highly basic and organic solvents.
The content of the invention
The technical problems to be solved by the invention are to provide one kind of multiple nonmetallic compound gravure printing rollers and its preparation side
Method, the gravure printing roller intensity is high, and in light weight, process will not produce toxic gas and pollutant, green, has good
Application prospect.
One kind of multiple nonmetallic compound gravure printing rollers of the present invention, including roller and the space of a whole page, the roller are carbon fiber
Pipe, the space of a whole page is modified graphene resin composite materials；Wherein, the modified graphene resin composite materials by epoxy resin, change
Property graphene and ceramic powder compounding and obtain.
The carbon fiber pipe is heating and curing through winding using carbon fiber wire pre-immersion resin and formed.
The mass ratio of the epoxy resin, modified graphene and ceramic powder is：1:0.005-0.01:0.03-0.05.
Engraved printing formes pattern on the modified graphene resin composite materials.
The preparation method of one kind of multiple nonmetallic compound gravure printing rollers of the present invention, including：
(1) by the dipped Resin Wound of carbon fibre tow to the core for scribbling releasing agent, in mandrel surface after the completion of winding
One layer of BOPP shrink film is wound again, solidifies, product is stripped from core, produces carbon fiber shell；Finally enter driving mill, obtain
To carbon fiber pipe；
(2) extracting epoxy resin, modified graphene and ceramic powder mix, and add curing agent and stir again
To no bubble, modified graphite olefine resin is obtained；Modified graphite olefine resin is applied on the carbon fiber pipe of preheating, rotation is solid
Change, finally in modified graphene resin surface engraved printing formes pattern, polished and cleaned produces a variety of nonmetallic compound gravure printing rollers.
Solidification temperature in the step (1) is 130-150 DEG C, hardening time 60min-150min.
Curing agent in the step (2) is curing agent.
Rotation solidification temperature in the step (2) is 70-90 DEG C, time 30min-60min.
The intensity of carbon fiber is more than 5 times of steel strength in the present invention, and proportion only has its 1/4, can instead of steel
Mitigate weight significantly while intensity is not weakened.
Modified graphene resin composite materials will not produce toxic gas and pollution in whole manufacturing process in the present invention
Thing, it is green.And after epoxy resin adds graphene and ceramic powder, reached the requirement of case hardness and abrasion resistance, and
It is easy to process and dimensionally stable is good.
Beneficial effect
Intensity of the present invention is high, and in light weight, process will not produce toxic gas and pollutant, green, has good
Good application prospect.
Brief description of the drawings
Fig. 1 is the structural representation before present invention engraving；
Fig. 2 is the structural representation after present invention engraving；
Fig. 3 is the sectional view of the present invention；
Wherein, 1 is carbon fiber pipe, and 2 be modified graphene resin composite materials.
Embodiment
With reference to specific embodiment, the present invention is expanded on further.It should be understood that these embodiments are merely to illustrate the present invention
Rather than limitation the scope of the present invention.In addition, it is to be understood that after the content of the invention lectured has been read, people in the art
Member can make various changes or modifications to the present invention, and these equivalent form of values equally fall within the application appended claims and limited
Scope.
Embodiment 1
(1) carbon fibre tow is immersed to the core for scribbling releasing agent by Resin Wound according to designed angle by wrapping machine
On mould, after the completion of carbon fiber wire winding, to prevent in winding process, there is gap between fibrous layer, surface winds one layer of BOPP again
Shrink film；After shrink film winding terminates, product is unloaded down from wrapping machine and is sent into baking oven, the rotation solidification 90 at 135 DEG C
Minute.After the completion of solidification, product is stripped from core and come out, then remove shrink film, products obtained therefrom is carbon fiber blank
Pipe.But carbon fiber shell now is not met by using, it is necessary to this carbon fiber shell is machined, and passes through car
Carbon fiber shell car into required length, is then put into processing excircles above grinding machine, reaches the Product Precision of needs by bed.Machine
After tool machines, the carbon dust of remained on surface is cleaned with acetone, carbon fiber pipe is put into baking oven after the completion of cleaning is preheated to 40
Next degree, which waits, to be used.
(2) extracting epoxy resin 500g, 0.5wt% modified graphene is added in order to increase the intensity of epoxy resin and toughness
2.5g, 3wt% hardening thickening ceramic powder 15g is added in order to increase the bonding force of epoxy resin and hardness, by three components
It is sufficiently stirred；To promote epoxy resin cure, the curing agent for adding 250g stirs until no bubble again.Will
Obtained mixture (being modified graphite olefine resin), is applied to above the carbon fiber pipe of preheating, baking oven is put into after the completion of smearing
Rotation solidification 35 minutes at 80 DEG C.After the completion of solidification, product is subjected to grinding according to drawing technical requirements, reaches product
Required required precision, meets print request.Finally completed in modified graphene resin surface engraved printing formes pattern, engraving
Afterwards, because engraving can produce burr, so needing to carry out the polished and cleaned on roll body surface again, produced after the completion of cleaning a variety of
Nonmetallic compound gravure printing roller.
