More specifically, the present invention relates to an abrasive material which is suitably used for various kinds of polishing such as barrel polishing and buffing, and which can be washed quickly and easily after polishing.

[0002]

2. Description of the Related Art Grounding for plating and painting, surface polishing for stainless steel, scale removal, deburring, chamfering, scouring,
The matte finish and basis weight are generally performed by mechanical polishing with an abrasive. Mechanical polishing includes a) barrel polishing,
b) polishing with a rotary tool typified by buff polishing, c) dry jetting with which powder is jetted, d) wet polishing with which an abrasive mixed with water is jetted, e) abrasive belt polishing, f) water or oil, etc. Examples include polishing with a high-pressure medium, g) polishing by pressurizing a viscous fluid containing an abrasive. Buffing is generally performed before surface processing such as plating of various metal articles made of iron, stainless steel, copper, brass, zinc, aluminum or the like. As a buffing abrasive, a fine powdery abrasive material is mixed with oil and solidified to be solidified, and an oily buffing material in the form of a rod is often used. This is due to frictional heat generated by pressing the rod-shaped abrasive against the buff. The fats and oils are dissolved, and the buff surface is coated with an abrasive, so that the buff surface is ready for polishing. In addition, depending on the purpose, a non-oil buffing abrasive formed by adding an abrasive material to a water-soluble adhesive and kneading and molding the same may be used. However, these conventional abrasives require ultrasonic cleaning in warm trichlorethylene (triclene), trichloroethane or ethylene chloride, or hydrochloric acid to remove the abrasive residue remaining on the abrasive article after the polishing process. Not only is it necessary to have a treatment facility such as a draft for that purpose, but all of the above chlorine-based cleaning solutions are dangerous, so caution is required when handling them, and the working environment is deteriorated. It was Among them, there are cleaning liquids such as trichlene whose use is prohibited depending on the local area itself. In addition, complicated shaped articles,
In the case of articles with severe irregularities or articles with many fine holes, the intricate parts and abrasives that have entered the holes can be easily removed by ultrasonic cleaning in the above-mentioned cleaning solution for a long time. However, the work efficiency was remarkably low.

[0003]

Under the circumstances as described above, there has been a strong demand in the art for a system that replaces the cleaning of articles after the polishing treatment using a chlorine-based solution. Therefore,
The present invention has been made to solve the above problems, particularly preferably used for barrel polishing and buff polishing, etc., of an abrasive material that can be washed after polishing quickly and easily without using trichlene, etc. The challenge is to provide.

[0004]

That is, the abrasive of the present invention comprises 0.1 to 10 parts by weight of at least one surfactant or degreasing agent based on 100 parts by weight of the abrasive material. To do. The present invention also includes an abrasive material 100.
The polishing material further comprises 0.1 to 500 parts by weight of the fibrous component with respect to parts by weight.

The abrasive material used in the present invention is a hard substance having a grinding action and a hard substance having a polishing action such as finishing and polishing of a machined surface, which are generally referred to as an abrasive and a polishing substance. It means a natural product or an artificial product. Examples of natural products include sandstone (emery), corundum, garnet, flint, gold sand, clays, talc, microcrystalline silicic acid, spinel, and silica sand, and artificial products such as synthetic diamond and cubic boron nitride. Alumina, silicon carbide, boron carbide, chromium oxide,
Examples thereof include cerium oxide, iron oxide, colloidal silicate, artificial emery, and fused zirconia. The type, particle size, particle size, etc. of the abrasive material are appropriately selected according to the object to be polished and the polishing method. The above-mentioned abrasive materials can be used alone or in combination of two or more.

The surfactant used in the present invention is
It is not particularly limited, and it may be any of anionic activators, cationic activators, nonionic activators and zwitterionic activators, or a mixture thereof. Typical examples of each are anion activators such as soap, sodium alkyl sulfate ester, sodium olefin sulfate ester, sodium alkylbenzenesulfonate, sodium alkylnaphthalenesulfonate, sodium oleate amidesulfonate, and sodium dialkylsulfosuccinate. , Cationic activators include halogenated trimethylaminoethyl alkylamides, alkylpyridinium sulfates, halogenated alkyltrimethylammonium salts, etc., and nonionic activators include polyoxyethylene alkyl ethers, polyoxyethylene fatty acid esters, polyoxyethylene There are alkyl phenyl ether, polyhydric alcohol fatty acid ester, polyoxyethylene polyhydric alcohol fatty acid ester, sucrose fatty acid ester, etc. The zwitterionic active agent is an alkyl trimethyl amino acid, and alkyl diethylenetriaminopentaacetic acid Te. In the present invention, among the above, alkyl sulfate ester salts, alkylbenzene sulfonates, fatty acid amide sulfonates, polyoxyethylene alkyl or alkyl phenyl ethers, etc. are the main components, and carbonates, alumina silicates, enzymes, etc. A household or industrial synthetic detergent in which is added is preferable in terms of availability and cost.

The degreasing agent used in the present invention is usually used for degreasing metal surfaces, such as sodium carbonate, sodium hydroxide, sodium phosphate, sodium tripolyphosphate, sodium silicate. , Sodium aluminate, borax, sodium hydrogen carbonate, chelating agents [eg ethylenediaminetetraacetic acid (EDTA), oxycarboxylic acid, etc.] and the like. Although only one kind may be used as the degreasing agent in the present invention, it is preferably used in a mixture blended in an appropriate ratio. Further, since the degreasing agent may cause corrosion depending on the material of the object to be polished, it is necessary to appropriately select the combination of the degreasing agent and the object to be polished. As this degreasing agent, commercially available immersion degreasing agents and electrolytic degreasing agents are preferably used for degreasing the metal surface, and in that case also, it is preferable to use a degreasing agent suitable for the material of the article to be polished. Needless to say. As a commercially available degreaser,
For example, Max Clean (trade name) manufactured by Kizai Co., Ltd.
And the Teion Cleaner (trade name) series and Asahi Cleaner (trade name) and U-Cleaner (trade name) series manufactured by Uemura Kogyo Co., Ltd.
In the present invention, by adding a surfactant and / or a degreasing agent to the abrasive material, the post-polishing cleaning of the article to be polished can be performed without using a chlorine-based solvent such as conventional trichlene,
Sufficient and reliable operation can be performed using warm water. Further, by adding a surfactant and / or a degreasing agent to the warm water for this cleaning, the article after polishing can be cleaned more effectively.

Next, the fibrous components which may be used in the present invention mean natural fibers and chemical fibers, and as examples of the former, vegetable fibers (wood fibers, cotton fibers, hemp fibers, etc.), animal fibers (wool). , Silk etc.) and mineral fibers (asbestos etc.)
Examples of the latter include inorganic fibers (glass fiber etc.), recycled fibers (rayon etc.), semi-synthetic fibers (acetate etc.),
There are synthetic fibers (nylon, etc.). Further, as the fibrous component, fibers regenerated from ready-made fiber products, such as plant fibers produced by boiling down paper (for example, newspaper, wrapping paper, thin paper, hybrid paper, etc.), can be used. Vegetable fibers from such papers are preferable in terms of availability and cost. The type and thickness of this fibrous component
The length and the like are appropriately selected in combination with the abrasive material. The fibrous component may also be used alone or in combination of two or more. By adding a fibrous component, the amount of sand stone (emery) as an abrasive material can be increased, and an abrasive material with better sharpness can be obtained. Also,
The paste-like abrasive material also has an advantage that it is hard to harden even if it comes into contact with air.

The content of each component of the above-mentioned abrasive is 0.1 to 10 parts by weight of the surfactant or degreasing agent to 100 parts by weight of the abrasive material as described above, and if desired, it may be added. Good fibrous component is 0.1 to 500
Parts by weight. The amount of the surfactant or degreasing agent blended is 0.
When the amount is less than 1 part by weight, when cleaning the article after polishing, the cleaning action of fine abrasive residue adhering to the article or entering the details of the article cannot be obtained, and even when it exceeds 10 parts by weight. This cleaning action not only reaches an equilibrium state, but also reduces the polishing power of the abrasive material, which is not preferable. If the blending amount of the fibrous component is less than 0.1 part by weight, the effect of the fiber is not exhibited, and if it exceeds 500 parts by weight, the shape of the solid or kneaded abrasive cannot be maintained, and This is not preferable because it reduces the polishing power of the abrasive material.

In addition to the above-mentioned components, fats, oils, paraffins and the like may be appropriately added to the abrasive of the present invention as long as the object of the present invention is not impaired. The oils and fats that can be used are mono- or tri-esters of fatty acids and triglycerin, which are widely present in the natural animal and plant kingdom,
Not only natural products but also synthetic products such as vegetable oils such as soybean oil, coconut oil, linseed oil, cottonseed oil, rapeseed oil, tung oil, castor oil, pine butter or tall oil, animal oils such as beef tallow, lanolin, whale oil, etc. Can be illustrated. The oil agent is obtained by processing the above-mentioned fats and oils, and includes, for example, hydrogenated hydrogenated fats and oils, fatty acids and glycerin obtained by hydrolysis of fats and oils, and other polyhydric alcohols. Representative examples of fatty acids include lauric acid, myristic acid, palmitic acid, stearic acid, oleic acid,
Behenic acid and the like. Further, as a paraffin, a straight chain or branched chain saturated hydrocarbon having about 10 to 40 carbon atoms,
For example, paraffin wax may be used.

Further, depending on the abrasive used in the present invention, it may be necessary to further add a binder in order to bond the above-mentioned abrasive material and other components. This can be appropriately selected from glue, glue, rubber cement, etc., which are generally called adhesives, depending on the type of abrasive material and other components used. Examples include natural products such as starch, dextrin, vegetable gum, animal and plant proteins, asphalt, shellac, natural rubber, sodium silicate, and the like, and synthetic products such as cellulosic resins, alkyds, acrylic esters, polyamides,
Polystyrene, synthetic rubber, polyvinyl alcohol, etc., thermosetting resins such as urea resin, melamine resin, phenol resin, resorcinol resin, furan resin, epoxy resin,
There are unsaturated polyesters and the like.

The abrasive of the present invention is produced by mixing appropriate amounts of the above components sequentially or simultaneously and subjecting the components to a treatment depending on the nature of each component used and the intended abrasive. In that case, if necessary, other components may be added to improve workability and the like. For example, a greasy rod-like buffing abrasive is made of fine powder of an abrasive material containing stearic acid, hardened oil, beef tallow, pine resin, paraffin, and other oils and fats, a surfactant and / or a degreasing agent, and optionally a fibrous component. It is manufactured by compounding and solidifying. Also,
The non-greasy one is obtained by adding a water-soluble binder such as glue or sodium silicate to fine powder of an abrasive material and kneading them. In addition, an abrasive component and a surfactant and / or a degreasing agent, and optionally a fibrous component,
It is also possible to add a binder, fats and oils, an oil agent and the like to prepare a barrel polishing abrasive by a conventional method.

Articles which can be polished with the abrasive of the present invention are:
It is anything that needs to be polished and may be made of metal or plastic. Specific examples thereof include metals such as iron and steel, non-ferrous metals, various alloys, and plastics such as vinyl resins which may be reinforced with fibers, phenol resins, urea resins, and melamine resins.
