Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rubber abrasive that can be used for buffing.

[0002]

2. Description of the Related Art Conventionally, polishing finishing requires a skilled operation using several kinds of abrasives and buffs. For example, finishing in polishing stainless steel is performed by sandpaper and nonwoven fabric. After the two steps, several buffing steps using cloth and the like were required.

[0003]

SUMMARY OF THE INVENTION The present invention provides a buff rubber abrasive material which enables such polishing and finishing to be performed very effectively with only one abrasive material having good operability. The challenge is to provide.

[0004]

SUMMARY OF THE INVENTION The present invention has solved the above problems by incorporating a polishing agent and an oily substance into a porous rubber abrasive.

The porous rubber may be any of open-cell rubber, closed-cell rubber and microporous rubber. For example, the open-cell rubber may be an agent such as sodium bicarbonate and tartaric acid which produces a gas by a reaction. In addition, closed-cell rubber
It is manufactured by kneading and vulcanizing an organic foaming agent such as neocerbon (manufactured by Eiwa Chemical Industry Co., Ltd.) into a rubber together with a vulcanizing agent, a vulcanization accelerator and other compounding agents. In addition, the microporous cellular rubber is made by dispersing a vulcanizing agent, a vulcanization accelerator and other compounding agents in the latex and adding a slow-speed coagulating agent such as ammonium sulfate to gel the latex. It can be manufactured by pouring, vulcanizing in hot water, washing and drying.

As the polishing agent, fine powder such as rouge, chrome green, talc, active stone, graphite, silicon carbide, alumina, etc. can be generally used. Particularly, a red stick after kneading with a glass surface polishing agent or wax, It is preferable to use a valve stem, chrome green, or the like, which is widely used as a blue bar for metal and other abrasives. These abrasives may be added at the time of kneading the rubber to produce an abrasive.

As a method for incorporating an oil quality such as a fatty oil or a mineral oil into the porous rubber, a necessary amount of oil quality may be kneaded at the time of kneading the rubber. Immerse rubber in oily material such as fatty oil or mineral oil,
Method of impregnating oily material into open cells, or emulsifying oily material with a surfactant or putting in a microcapsule,
A method of dispersing in rubber latex and gelling or vulcanizing the same can also be applied.

Further, when the abrasive is used, the oil quality can be gradually replenished to the porous rubber containing the abrasive. This is because in a disk-shaped abrasive that is rotated and used, a porous rubber body containing an abrasive is arranged around the oil chamber, an oil chamber is provided in the center, and centrifugal force is applied from the oil chamber to the porosity. This can be achieved by allowing the oil quality to transfer to the rubber body. As this oil chamber, for example, a porous molded body such as cork or a foamed resin molded body filled with oily substance, or a metal container containing oily substance can be used. It should be noted that the oil chamber has, of course, pores for oil quality supply on the surface in contact with the porous rubber body containing the abrasive, and the oil chamber is further provided with a mouth for oil quality replenishment. preferable.

As described above, according to the present invention, the three properties of porous rubber, oily material and abrasive are effectively used, and the rubber abrasive can be used very effectively for buffing. To do. That is, according to the abrasive of the present invention, by the above-mentioned three actions, the surface of the object to be polished is finished to be a glossy and very smooth surface in a very short period of time with very good operability. Can be done.

If desired, fine powder of alumina, carborundum or other hard abrasives may be mixed in addition to abrasives such as valve stems and chrome green to form fine scratches and irregularities on the surface of the object to be polished. It can be made flat by the action of fine alumina, carborundum, etc., and by the action of oil quality, valve stem, chrome green, etc., it can have a glossy and very smooth surface. Furthermore, when the buffing porous rubber abrasive material of the present invention is made soft and can be used for buffing work, a metal or synthetic resin plate or the like may be bonded and reinforced to the rubber abrasive material. This reinforcement can be done on a surface that does not interfere with work, for example, in the case of a disk-shaped porous rubber abrasive, when the flat surface of the disk is used, on the opposite back surface, or when the circumference is used, This can be achieved by adhering a metal or synthetic resin disk or the like to the disk surface.
