Description
Technical field
The utility model relates to magnetic sheet, particularly a kind of halogen-free environment-friendly type high-performance diskette.
Background technology
Magnetic sheet is a kind of magnetic material that is widely used.The general binding agent that adopts of traditional diskette is generally the Halogen high polymer binders such as CPE, CSM, easily causes the product Halogen to exceed standard, and do not meet security performance, and its mobile performance, physical property and ageing resistace is relatively low.What traditional diskette adopted is simply to mix sandwich, merely magnetic material is mixed in the binding agent, and then double team gets up; Because it is simple in structure unreasonable, exist magnetic low and be difficult to keep stable, easily the deficiency such as aging, fragile.
The utility model content
For above-mentioned deficiency, the purpose of this utility model is, the halogen-free environment-friendly type high-performance diskette of a kind of structure optimization, Environmental Safety is provided.
The technical scheme that the utility model adopts for achieving the above object is:
A kind of halogen-free environment-friendly type high-performance diskette is characterized in that: it comprises flexible protective layer, compliant conductive layer and the flexible magnetic layer that sets gradually, and the left magnetic section that described flexible magnetic layer is arranged by order, middle magnetic section and right magnetic section form; Described left magnetic section and right magnetic section are granular even formula magnetic cohesive body; Described middle magnetic section is powdery laminar magnetic cohesive body.
Described granular even formula magnetic cohesive body is mixed by granular magnetic and Halogen high polymer binder, and described granular magnetic has insulating coating and is uniformly distributed in the Halogen high polymer binder; Described powdery laminar magnetic cohesive body is mixed by pulverous magnetic and Halogen high polymer binder, and described pulverous magnetic is stacked to be distributed in the Halogen high polymer binder.
Described left magnetic section and right magnetic section are symmetrical arranged and are mutually excessive with middle magnetic section by the oiliness insulating barrier, and middle magnetic section is clipped in the middle.The both sides symmetrical structure can play the effects such as magnetic stability that strengthen magnetic and keep diskette like this, and in addition, such structure setting allows whole diskette more be not easy infringement, and is counter-bending, cracking resistance.
The granular magnetic of described left magnetic section and right magnetic section is granular ferrimagnetism material.Pulverous magnetic of described middle magnetic section is pulverous rubidium iron boron magnetic material.Described Halogen high polymer binder is thermoplastic elastomer (TPE).The insulating coating that described granular magnetic has is that granular magnetic soaks in insulating coating solution and then picks up formation.Described compliant conductive layer is that conducting polymer composite forms.This halogen-free environment-friendly type high-performance diskette all material adopts the halogen-free environmental shaped material.
This halogen-free environment-friendly type high-performance diskette is integrated extrusion modling.By the extruding, roll of magnetic, the high filling of magnetic grain, obtain the parameters such as the tearing strength of optimum pardon and goods and elongation at break, obtain best magnetic property.
The utility model has the advantage of: by flexible protective layer, compliant conductive layer and flexible magnetic layer are set; and the structure of flexible magnetic layer and composition are done further optimization improve the halogen-free environment-friendly type high-performance diskette that has obtained high magnetic, high stability and done environmental-protecting performance.
Below in conjunction with accompanying drawing and embodiment, the utility model is further specified.
