The guide roller comprises an iron core, wherein an epoxy coating layer is coated on the iron core, an adhesive layer is coated on the epoxy coating layer; and a polymer layer is coated on the adhesive layer. The guide roller has simple structure and reasonable design; the guide roller which has a single-layered structure in the prior art is changed into a three-layered structure, i.e. the epoxy coating layer, the adhesive layer and the polymer layer, and the three-layered structure can be firmly combined with the iron core in a coating manner and has excellent wear resistance and chemical corrosion resistance; moreover, the guide roller can be simply produced and is suitable for batch production and manufacture.
Description
Technical field
The utility model belongs to the deflector roll technical field of papermaking and dyeing.
Background technology
The deflector roll that papermaking and dyeing are used is because of contacting with water and corrosive liquids for a long time, and roll surface is easy to get rusty.In order to solve the problem that deflector roll gets rusty, present deflector roll adopts following structures to make:
1) rubber-faced deflector roll, promptly on iron core, coat one deck rubber layer is set, this rubber layer is the clad can of logical rolled-to-death rubber, iron core processing, encapsulate, sulfuration, the formation of car mill, the advantage of this clad can is that the iron core surface does not need special processing, only after the sandblast, but with regard to encapsulate, the clad can of its manufacturing can be made the clad can of various instructions for uses according to the random conversion prescription of different instructions for uses, glue kind, hardness.
2) chromium plating clad can deflector roll is promptly electroplated one deck thickness and is about the compact metal chromium of 0.05-0.5mm as anticorrosive coat on iron core.
3) metallic cover clad can deflector roll promptly coats stainless steel or the layer of brass that a layer thickness is about 1mm at iron core, and solder joint obtains antiseptic and rustproof clad can after polishing then.
Above-mentioned clad can respectively has characteristics, and rubber-faced is easily manufactured, uses the extensivelyst, but complex process needs sulfuration; The chromium plating clad can is simple, but iron core need finish grind, and this clad can not be collided, otherwise easily causes defective, and clad can is extremely short service life after the corrosion; Stainless steel brass coating clad can surface accuracy is poor, and it is big to beat, and can not be used for high-speed case, but under low-speed conditions, the life-span is longer.
Summary of the invention
At the problem that prior art exists, the purpose of this utility model is to design the technical scheme that a kind of deflector roll is provided, and this deflector roll has excellent abrasive and chemical resistance.
Described a kind of deflector roll comprises iron core, it is characterized in that coating on the described iron core epoxy coating is set, and coats on the described epoxy coating adhesive-layer is set, and coats on the described adhesive-layer high polymer layer is set.
Described a kind of deflector roll is characterized in that described epoxy coating thickness is 0.1-1mm.
Described a kind of deflector roll is characterized in that described adhesive-layer is a hot melt adhesive layer.
Described a kind of deflector roll is characterized in that described adhesive-layer thickness is 0.3-0.5mm.
Described a kind of deflector roll is characterized in that described high polymer layer is polyethylene and polypropylene layer.
Described a kind of deflector roll is characterized in that described high polymer layer thickness is 4-5mm.
Above-mentioned a kind of deflector roll, simple in structure, reasonable in design, change the single layer structure of the central deflector roll of prior art, deflector roll is arranged to epoxy coating, adhesive-layer and high polymer layer three-decker, and this three-decker can firmly coat with iron core and combine, and has excellent abrasive and chemical resistance, and this deflector roll production method is simple, is convenient to produce by batch manufacturing.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the internal structure schematic diagram of deflector roll in the utility model.
Among the figure: the 1-iron core; The 2-epoxy coating; The 3-adhesive-layer; The 4-high polymer layer.
The specific embodiment
Further specify the utility model below in conjunction with Figure of description.
As shown in the figure, a kind of deflector roll comprises iron core 1, and iron core 1 has passed through the surface sand-blasting preliminary treatment and removed rusty stain before production, and cleans ungrease treatment with gasoline.Coat on the surface of iron core 1 and be provided with epoxy coating 2, the thickness of epoxy coating 2 is greater than 1mm.Epoxy resin in the epoxy coating 2 is a kind of pressed powder, comprises epoxy resin, curing agent and modifier in this component, after thermal spraying, can and solidify with iron core 1 secure bond.
Adhesive-layer 3 surfaces are gone up to coat and are provided with the high polymer layer 4 that thickness is 4-5mm, and this high polymer layer 4 is polyethylene and polypropylene layer, and this layer has higher hear resistance, corrosion resistance and good wearability.
Deflector roll of the present utility model can be made by following production technology and obtain:
Iron core sandblast → surperficial preheating → epoxy resin thermal spraying → adhesive layer → high temperature extruded polyethylene/polypropylene → water cooling → car mill.
Rusty stain is removed through sandblasting pretreatment in iron core 1 surface, increase surface roughness, to increase adhesion strength, clean with gasoline then, carry out ungrease treatment, the iron core of handling well 1 is held on the wrapping machine grain-clamping table, the winding of wrapping machine partly is made up of intermediate frequency heater, thermal spraying machine, intermediate layer bundling machine, polyethylene/polypropylene heat posted machine four parts, wherein intermediate frequency heater, thermal spraying machine are positioned at wrapping machine left side mobile platform, intermediate layer bundling machine, polyethylene/polypropylene heat posted machine are positioned at wrapping machine right side mobile platform, and they form a continuous processing line.Open linked switch, the roller uniform rotation, the left side mobile platform laterally moves, earlier by intermediate frequency heater preheating roll surface, followed by thermal spraying epoxy coating 2, then the right side mobile platform laterally moves, earlier by the intermediate layer bundling machine on epoxy coating 2 in the shape of a spiral line coat adhesive-layer 3, followed by polyethylene/polypropylene heat posted machine line coated high molecular polymeric layer 4 in the shape of a spiral on adhesive-layer 3, finish the back machine down that coats, after water-cooled, enter car grinder preface, finish clad can processing.
The deflector roll that adopts said method to make gets up the interfacial characteristics of epoxy coating 2 and the advantages such as physical mechanical characteristic of chemically-resistant characteristic and high polymer layer 4, thereby has significantly improved performance separately.The clad can mechanical strength height of this deflector roll, wear-resistant, corrosion-resistant, high-low temperature resistant, can be applicable in various environment, all show superperformance in the 0-120 degree medium Celsius.This has great meaning for the deflector roll that uses under different condition.
Shown in the above and the figure only is preferred implementation of the present utility model.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model principle, can also make some modification and improvement, these also should be considered as belonging to protection domain of the present utility model.
