Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention provides a compound with either corn cob or rice husk powder, or both, or by adding either corn cob or rice husk powder, or both, to obtain a good gloss finish. The present invention relates to a barrel polishing compound and a barrel polishing method for obtaining the same.

[0002]

2. Description of the Related Art Conventional barrel polishing compounds have a lubricating action, a cleaning action, a foaming action, a rust preventive action, a degreasing action, etc., and are required in order to improve the surface condition of a workpiece after polishing. It was used appropriately.

[0003]

However, the compounds conventionally used have a problem that the gloss of the finished surface is insufficient. In particular, stainless steel workpieces have a problem that black smut adheres to the surface after polishing.

Attempts have also been made to add wood flour to the compound, but satisfactory results have not been obtained.

[0005]

Therefore, according to the present invention, either one or both of corn cob (powder obtained by crushing corn core) or rice husk powder is added to the compound, or either corn cob or rice husk powder is added into the polishing tank. The above conventional problems were solved by charging one or both of them separately from the compound and polishing.

[0006] That is, the present invention is a barrel polishing compound characterized in that an appropriate amount of either one or both of corncob and chaff powder is added to a compound containing a surfactant as a main component for barrel polishing. Still another invention is a compound for barrel polishing, characterized in that an appropriate amount of either one or both of corn cob or chaff powder and wood powder is added to a compound containing a surfactant used for barrel polishing as a compound. Is a surface active agent and one or a mixture of two or more kinds of a rust preventive agent, a chelating agent or a cleaning aid. Next, in the invention of the method, it is appropriate that the addition amount of either or both of corn cob and chaff powder is 5% by weight or more based on the total amount of the compound for barrel polishing. 5%
If it is less than 1, good gloss finish cannot be obtained. As for the size of either or both of corn cob and rice husk powder, fine particles of # 60 or more are suitable. Coarse particles of less than # 60 are less effective in improving gloss. Still another invention is to put a workpiece, an abrasive, a compound of corn cob or rice husk powder, or both, and water into a polishing tank and polish the tank such as rotary motion, planetary motion or vibration. It is a barrel polishing method characterized by imparting necessary movement and polishing, characterized in that either or both of corn cob and rice husk powder are charged alone or added to a compound and charged. It is a thing.

The above-mentioned surfactants include fatty acid salts (for example, sodium laurate, sodium palmitate, sodium stearate, sodium oleate, etc.), sulfonates (for example, alkylallyl sodium sulfonate, etc.), alcohol sulfates ( For example, anionic surfactants such as sodium lauryl alcohol sulfate and the like) and polyethylene glycol.
Nonionic surfactants such as monolaurate, polyoxyethylene oleyl ether, polyoxyethylene alkyl allyl ether, polyoxyethylene sorbitan monolaurate, and alkylol amide (eg coconut oil fatty acid diethanolamide), etc., alone or Use by mixing. The surfactant is used for the purpose of exerting a cleaning action, a glossing action and a lubricating action on the work piece.

Examples of the rust preventive used in the present invention include nitrite, borate, phosphate, aromatic carboxylate,
Etc. are used alone or in combination. Examples of the chelating agent used in the present invention include oxycarboxylic acids (eg citric acid, malic acid, tartaric acid, glycolic acid, gluconic acid, etc.)
Alternatively, a salt thereof, aminopolycarboxylic acid, (for example, ethylenediaminetetraacetic acid, diethylenetriaminepentaacetic acid, nitrilotriacetic acid, glycol etherdiaminetetraacetic acid, etc.), a salt thereof, or the like is used alone or in combination. The chelating agent has a water softening effect.

Further, as the cleaning aid used in the present invention,
For example, powdered fibrin (wood flour or the like), carboxymethyl cellulose or the like is used.

[0010]

According to the present invention, in barrel polishing,
Since either or both of corncob and rice husk powder were added in the compound or during polishing, the black smut adhering to the surface of the workpiece was removed, and a whiter and better gloss finish could be obtained. It is considered that this is because corn cob or rice husk powder is a denser and more porous fibrous material than wood powder, and thus has a high effect of adsorbing or wiping dirt such as smut.

Wood powder has a long cellulose fiber length and a large fiber structure, but corncob powder and rice husk powder have a short fiber length, a round crystal state, and almost no fiber structure. #
Bulk density of 120 wood flour is 0.24Kg / l, while # 12
For corn cob flour of 0, 0.44 kg / l, and for rice husk flour, 0.
It has a bulk specific gravity of 57 Kg / l, which is about twice as high. With the increase in bulk specific gravity, the productivity of the compound is improved, and the packaging cost, storage space and transportation cost can be reduced. Furthermore, in the compound using wood flour, there was a problem that long fibers were clogged in the fine part of the work, but it was almost solved in the case of corncob flour and rice husk fine powder.

[Example 2] The same conditions as in Example 1 were used except that a polishing stone 3P-10 for micro-cutting gloss manufactured by Tipton Co., Ltd. was used as the polishing stone, and 50 center cores of SUS floppy disks were loaded as workpieces. The smut test was carried out at. 3P-10 was used for the smut test because the smut adhered to the 3P-10 was higher when the SUS component was polished than the HCS-4.

Table 4 shows the test results. It has been found that the compounds II and III of the present invention have a lower smut adhesion rate and a higher detergency than the conventional compound I.
