Description

[Detailed description of the invention] The present invention relates to polishing fluid compositions.

Surface polishing of iron and special alloys in the surface treatment industry plays a major role in determining the commercial value of the product itself.

[1] Utilizing the anodic melting phenomenon, polishing can be applied to carbon steel, high carbon steel, special steel, yellow steel, aluminum and aluminum alloy 18/8 stainless steel, silver, gold, nickel, nickel chrome alloys, spring steel, high Electrolytic polishing for high-speed steel, plastics, etc. to give a glossy finish, a super finish, and a deburring effect.
Chemical polishing aimed at brightening and smoothing cadmium, yellow steel, copper, aluminum and aluminum alloys, nickel carbon steel, etc. Cloth polishing to obtain a smooth surface, '41 Barrel polishing, which uses surfactants such as acids or alkalis and soaps as lubricants and, if necessary, an abrasive, to polish metal surfaces in a rotating container, etc. They are used alone or in layers depending on the purpose and material of the product, such as metal top plastics.

On the other hand, since the surfaces of metal and plastic parts do not have individual stains such as animal and vegetable oils, mineral oils, greases, waxes, carbides of these, metal oxide films, and inorganic substances, compound stains are often removed and polished. It is necessary to obtain metal products with excellent durability and gloss.

Acidic electropolishing is performed using mineral acids such as nitric acid, sulfuric acid, phosphoric acid, and hydrochloric acid in combination with an organic acid surfactant in some cases, but it does not have scale removal properties. However, it has poor degreasing properties.

On the other hand, alkaline electrolytic polishing, which uses alkaline salts such as caustic soda, phosphates, and carbonates, and in some cases organic hydrochloric acid and surfactants, has degreasing properties, but does not have sufficient scale removal properties. . In addition, chemical polishing uses a scale acid such as nitric acid, sulfuric acid, phosphoric acid, or hydrochloric acid in combination with an organic acid and a surfactant depending on the case, and the degreasing properties are similarly poor. In most cases, barrel polishing uses alkaline salts such as phosphates and leech nitrates, anionic surfactants such as soap, nonionic surfactants, and sometimes abrasives, but it is difficult to remove complex dirt-like substances. Scale removal: "Both degreasing properties are not sufficient, and re-deposition of dirt is also a problem.

The inventors of the present invention have strived to solve these problems and have arrived at the present invention as a result of intensive research.

That is, oxycarboxylic acid or its salt (10-9 parts by weight), aminopolycarboxylic acid or its salt (10-9 parts by weight)
The present invention provides a polishing liquid composition characterized in that it contains a surfactant (1-2 parts by weight) as essential components.

Oxycarposoic acid or its salt, aminocarboxylic acid or its salt, and surfactant, which are essential components in the present invention, can be used alone or in combination.

In addition, as auxiliary ingredients, m nitric acid, sulfuric acid, hydrochloric acid, phosphoric acid,
Inorganic salts such as hydrochloric acid '2' Inorganic alkaline salts such as caustic soda, phosphates, carbonates, silicates, borates (sodium, potassium, ammonium, etc.) Glue Hydrogen peroxide,
Alcohol, glycerin, agar, glue, etc.'4) Fatty acid salts (potassium, sodium, ammonium, etc.)'
5} It is possible to use one or more abrasives in combination, and the polishing liquid composition has excellent abrasive properties and gloss against stains alone or in combination.

In the present invention, examples of oxycarboxylic acids or salts thereof include gluconic acid, citric acid, malic acid, tartaric acid, lactic acid,
Glycolic acid or its salts such as sodium, potassium, ammonium, etc.

Examples of aminopolycarboxylic acids or salts thereof include nitrilotriacetic acid, ethylenediaminetetraacetic acid, diethylenetriaminepentaacetic acid, glycol ether diaminetetraacetic acid, 1,2
- Cyclohexanediaminetetraacetic acid or its sodium, potassium, ammonium, etc. salts.

As surfactants, nonionic surfactants (polyoxyalkyl ether type,
Polyoxyethylene alkyl phenyl ether type, etc.) Anionic surfactants (Sulfuric acid or phosphate esters and salts of polyoxyethylene alkyl ether or polyoxyethylene alkyl phenyl ether, etc.) Cationic surfactants (Pyridium type or amine type) amphoteric surfactants (alkylcarboxybetaine type, alkylaminocarboxylic acid type, alkylimidazoline type, etc.).

Next, the composition ratio of the polishing liquid composition of the present invention will be explained.

The amount of the oxycarbosic acid or its salt is 10-90 parts by weight, preferably 30-6 parts by weight, and if it is less than IQ parts by weight, the degreasing property is particularly poor. The amount of aminopolycarboxylic acid or its salt is 10-5 parts by weight, preferably 20-5 parts by weight, and if it is less than 1 part by weight, the scale removal properties are particularly poor.

The amount of the surfactant is 1-2 parts by weight, preferably 5-20 parts by weight, and if it is less than 1 part by weight, the degreasing and scale removal properties are poor.

Note that water or auxiliary ingredients can be blended in an amount of 0-90% with respect to the present composition.

The polishing liquid composition of the present invention is a polishing liquid composition that has excellent surface abrasiveness and gloss against single or multiple contamination of iron, special alloys, plastics, etc., and can contain any auxiliary components singly or in combination. It is a polishing liquid composition.

Next, the present invention will be explained in detail by way of examples. (Department,
(% indicates weight basis) Example 1 (Electrolytic polishing of coin bronze (Sn3-8%)) Mobil oil 8 anchors on a clean coin bronze steel plate (length 100, rib width 50, rib thickness 0.3 willow) A mixed oil consisting of 2 parts of soybean oil was coated every 20 minutes and treated in a ~400 oo electric furnace for 30 seconds to prepare a non-polished surface.

As a polishing liquid composition, prepare 5% sodium carbonate, 50% sodium phosphate, 50% sodium phosphate, and use the polished material as an anode. (Cathode is copper rice) 4A/d pillow 50pm 03
Tochi everyone did electrolytic polishing.

Similarly, those which were electrolytically polished with sodium carbonate 150 mm/s, sodium phosphate 100 mm/s, or those lacking either of the compositions of the present invention were inferior in gloss compared to the compositions of the present invention. Example 2 (Chemical polishing of 18/8 stainless steel plate) An 18/8 stainless steel plate (length: 5 x width: 5 x rib thickness: 3 willow) was coated with calcium stearate of 202/m2 and 600
The grain to be polished was prepared by sand treatment at 3°C in an electric furnace.
