Flap disc with blades being not prone to falling off and bonder of flap disc

Abstract

The invention discloses a flap disc with blades being not prone to falling off. The flap disc comprises a tray and the abrasive cloth blades; the tray is provided with a bearing hole matched with a bearing; a two-stage stepped tray is used as the tray; the tray comprises a first-stage circular-truncated-cone tray and a second-stage circular-truncated-cone tray; the abrasive cloth blades are bondedon the first-stage circular-truncated-cone tray; the outer circumference of the first-stage circular-truncated-cone tray is provided with a mounting groove; the abrasive cloth blades are circumferentially and evenly distributed in the mounting groove of the outer circumference of the first-stage circular-truncated-cone tray; the space between the abrasive cloth blades and the mounting groove is filled with a bonder layer; a bonder injection hole is formed in the side face of the first-stage circular-truncated-cone tray; the second-stage circular-truncated-cone tray is provided with radiatingholes; and the inner wall of the bearing hole is provided with a thread matched with the flap disc bearing. The flap disc with the blades being not prone to falling off is long in service life, the blades are not prone to falling off, and meanwhile, the heat dissipation performance is good. The invention further discloses a bonder for effectively bonding the blades and a bonder preparation method.

Description

technical field [0001] The invention relates to the technical field of louvers, in particular to a louver whose blades are not easy to fall off and an adhesive thereof. Background technique [0002] The shutter wheel (louver wheel) is called a strong elastic grinding disc, which is made of a plastic or fiber mesh cover and a sheet of emery cloth. The shutter wheel is a simplified product of the flap wheel, which is mainly used for grinding and polishing in industrial production, and is also a kind of industrial consumable products. The base of the impeller is made of mesh, nylon, plastic, steel paper, etc., and the number of sheets varies, and they are fan-shaped and evenly distributed. Mainly used in grinding and polishing of various stainless steel and carbon steel structural parts. [0003] When the louver wheel in the prior art is in use, the emery cloth blades are bonded to the tray. On the one hand, the adhesion effect in the prior art is poor, and the emery cloth wh...

AI Technical Summary

Problems solved by technology

[0003] When the louver wheel in the prior art is in use, the emery cloth blades are bonded to the tray. On the one hand, the adhesion effect in the prior art is poor, and the emery cloth wheel blades are easy to fall off. For example, Chinese patent CN201520043812.4 discloses a two- The louver wheel with a meta-structured base is characterized in that a viscose stress ring and a viscose synchronous consumption circle are set at the base viscose; a viscose synchronous consumption circle is arranged around the viscose force circle; The width and thickness of the circle are set within a certain range, and the thickness value of the viscose synchronous consumption circle is set to be less than or equal to the thickness value of the viscose stress circle; the width of the viscose force circle is set to have the same thickness horizontal shape or a decreasing slope shape; the width of the viscose synchronous consumption ring is set in the same thickness horizontal shape or in a decreasing slope shape. In the prior art, the blades are directly bonded to the tray with an adhesive, and the blades are easy to fall off after a long time of use. At the same time, the amount of binder used is large, which wastes resources; at the same time, the heat dissipation performance of the louver in the prior art is poor, and the service life of the louver is short

[0004] On the other hand, the adhesive in the prior art has a general adhesion effect, and after a period of use, the emery cloth blades are easy to fall off, and the service life of the louvers is short.
