Description
Technical field
The present invention relates to flap disc technical field, specially a kind of flap disc and its binder that blade is not easily to fall off.
Background technique
Flap disc (louver wheel) is known as strong elastic mill, is to be formed by plastics or fiber square are viscous with emery cloth hinge.Hundred
Impeller is a kind of simplified product of sized flap wheel, the sanding and polishing being mainly used in industrial production, and belongs to industrial consumptive material and produce
One kind of product.Impeller matrix has screen cloth, nylon, plastics, vulcan fibre etc., and more or less for hinge, fan-shaped to be uniformly distributed.Main application
In the grinding and polishing treatment of various stainless steels and carbon steel structure part.
When in use, emery cloth blade is bonded on pallet flap disc in the prior art, on the one hand, in the prior art viscous
Attached effect is poor, and emery cloth impeller blade is easy to fall off, and such as Chinese patent CN201520043812.4, discloses a kind of diadactic structure formula base
The flap disc of body, it is characterised in that viscose glue stress circle and viscose glue synchronous consumption circle are set at matrix viscose glue；Viscose glue stress circle periphery
Viscose glue synchronous consumption circle is set；Viscose glue stress circle and viscose glue synchronous consumption circle width and thickness are arranged in a certain range, and viscose glue is same
Step consumption circle thickness value be set smaller than or equal to viscose glue stress circle thickness value；Viscose glue stress circle is arranged on the width in same
One thickness level shape or the ramped shaped to taper off；Viscose glue synchronous consumption circle be arranged on the width in same thickness level shape or
Blade is directly bonded on pallet using binder by the ramped shaped to taper off in the prior art, blade using after of long duration,
It is easy to fall off, meanwhile, the usage amount of binder is big, waste of resource；Meanwhile the heat dissipation performance of flap disc in the prior art compared with
The service life of difference, flap disc is short.
On the other hand, binder in the prior art, adhesiving effect is general, and after a period of use, emery cloth blade is easy
It falls off, the service life of flap disc is short.Therefore it is badly in need of a binder, realizes effective bonded abrasive wheel blade.
Summary of the invention
To solve the above problems, the invention discloses a kind of flap disc that blade is not easily to fall off, the service life of flap disc
Long, blade is not easily to fall off, reduces the use of binder, meanwhile, perfect heat-dissipating.It also discloses and effectively adheres to the viscous of blade
Tie the preparation method of agent and binder.
In order to reach the goals above, the invention provides the following technical scheme:
