Description of the Related Art As a polishing buff used for glossy finishing of automobiles, a disc-shaped polishing buff made of platix having continuous pores such as polyurethane foam having a polishing surface on a bottom surface and a connection portion with a rotating tool on an upper surface. Although it is used, the abrasive impregnated in the disk-shaped main body composed of plattix having continuous pores is scattered from the peripheral surface by the centrifugal force during the polishing work, so that the working environment is deteriorated. In addition, there are various problems such as large waste of abrasive.

[0003]

The problem to be solved by the present invention is to solve the above-mentioned conventional problems and to solve the problem that the abrasive impregnated in the disk-shaped main body is subjected to centrifugal force during the polishing operation involving high-speed rotation. An object of the present invention is to provide a polishing buff with high polishing efficiency, which does not scatter from the peripheral surface of the disk-shaped main body, and thereby reduces the working environment and wastes abrasive.

[0004]

SUMMARY OF THE INVENTION A polishing buff according to the present invention, which has been made to solve the above-mentioned problems, has a platchx having a myriad of continuous pores having a bottom surface as a polishing surface and an upper surface as a connecting portion with a rotary tool. The disk-shaped peripheral surface of the elastic main body is covered with a non-porous film. In this polishing buff, the non-porous film is formed of a non-porous film made of a plastics similar to the elastic main body, which is adhered and integrated on the peripheral surface of the elastic main body. The invention according to claim 3, wherein the non-porous coating is formed into a non-porous layer by forming the non-porous coating integrally on the peripheral surface of the elastic main body by using the same material as the elastic main body. In each of the polishing buffs described above, the peripheral surface mainly composed of an elastic body is formed as a gentle concave arc surface according to the invention according to claim 4, and further, in each of the above-described inventions, the surface condition provided on the rotary tool side is further described. The invention according to claim 5 is the one wherein a planar fastener forming a pair with the fastener is adhered to an upper surface mainly composed of an elastic body.

[0005]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below. Reference numeral 1 denotes a disc-shaped elastic main body made of a polyurethane foam having an infinite number of continuous pores having a diameter of, for example, 200 mm and a thickness of 40 mm. On the upper surface of the elastic main body 1, a female planar fastener 3 paired with a male planar fastener provided on the rotary tool is provided except for a central portion so that the elastic main body 1 can be easily attached to a rotary tool (not shown). It is attached almost entirely. The planar fastener referred to here is a male member on which countless hooks are planted, such as those marketed under the trade name Magic Tape, and countless loops that engage with the hooks. Of the female side member.

In the present invention, the peripheral surface of the disc-shaped elastic main body 1 made of polyurethane foam having countless continuous pores is covered with a non-porous coating 2. Further, in this embodiment, the peripheral surface of the elastic main body 1 is formed as a gentle concave arc surface as shown in the drawing, so that the elastic main body 1 is added during the polishing operation despite the non-porous coating 2 being on the peripheral surface. Although the pressure is applied so as to easily follow the applied pressure, it is needless to say that the peripheral surface may be a vertical surface. In addition, as the non-porous coating 2 covering the peripheral surface of the elastic main body 1,
Generally, a non-porous film is adhered and integrated with an adhesive such as an adhesive on the peripheral surface of the elastic main body 1. In this case, the non-porous film has excellent adhesive strength with the elastic main body 1. In addition, since the elastic body 1 preferably has the same degree of elasticity as the elastic body 1, the elastic body 1 is made of polyurethane foam. In this embodiment, a similar urethane resin film is used. If it is molded with a system integral skinned foam, the peripheral surface in contact with the mold surface can be integrally molded with the elastic main body 1 having continuous pores from the same material to form a non-porous layer. .

[0007] A non-porous film as a non-porous film 2 is integrally bonded to the peripheral surface of an elastic main body 1 of a polyurethane foam having a gentle concave arc surface as described above. In the case of manufacturing, for example, a cylindrical body made of polyurethane foam having an infinite number of continuous pores is formed, and then a urethane resin film is wound around the peripheral surface of the cylindrical body via an adhesive and then heated and pressed. If the urethane resin film is stuck and integrated on the peripheral surface of the cylindrical body, and finally cut to the required length, the peripheral surface of the elastic main body 1 naturally becomes a gentle concave arc surface due to the pressure at the time of cutting. (1) It can be provided at a lower cost as compared with the one molded by one.

[0008] The above-mentioned structure is achieved by engaging a female planar fastener 3 attached to the upper surface of a male planar fastener provided on the rotating tool (not shown) with an abutment. The elastic main body 1 is mounted on a rotating tool, and the rotating main body is driven to rotate the elastic main body 1 at a high speed so that a polishing surface 1a on a lower surface thereof is brought into contact with a surface to be polished such as a body of an automobile. Polishing with a liquid abrasive supplied between the polishing pad and the surface to be polished is the same as that of a conventional polishing buff of this type, but the periphery of a disk-shaped elastic main body 1 made of platchix having continuous pores. Since the surface is covered with the non-porous film 2 integral with the surface, the abrasive impregnated in the continuous pores of the disk-shaped main body 1 is subjected to centrifugal force during the polishing operation involving high-speed rotation in the circumferential direction of the disk-shaped main body 1. Non-porous coating 2 can accurately prevent the deterioration of the working environment such as the scattering of the abrasive to the surroundings and the contamination of the surroundings, or the adverse effect on the health of the worker, and the prevention of the scattering of the abrasive by preventing the abrasive from scattering. This is economical and has the effect of preventing burns. Further, the reinforcing effect of the non-porous coating 2 makes the elastic main body 1 durable for a long period of time.

[0009]

As apparent from the above description, the present invention provides:
With a simple structure that only covers the peripheral surface of the elastic main body with countless continuous pores with a non-porous coating, the abrasive impregnated with the elastic main body scatters from the peripheral surface of the disk-shaped main body due to centrifugal force and the surrounding work environment In addition to this, there is no economical advantage such that the abrasive is not wasted, the abrasive is not wasted, and long-term durability can be achieved. Therefore, the present invention greatly contributes to industrial development as a solution to the problem of the conventional polishing buff of this type.
