Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a cleaning material, and more particularly to a cleaning material for articles such as electrical products, audio products, optical products, etc., which are prone to attract dust.

[Conventional technology]

Electrical products such as televisions, word processors, vacuum cleaners, air purifiers, and electrostatic printers; audio products such as records, record needles, and tape carriers; optical products such as lenses, glasses, and cameras; bearings, shaft sealing devices, etc. In this case, dust easily adheres to the surface charged by friction or magnetism, and it is difficult to remove the attached dust and other stains. Conventionally, dirt such as dust that has adhered due to static electricity has been removed by using a brush made of chargeable thread or the like. However, surfaces cleaned by such mechanical methods quickly become charged and contaminated.

Therefore, cleaning with a cleaning agent is performed, but since many of the surfaces of the items mentioned above cannot be washed with water or cleaning agents, conventional methods have been to wipe them with a cloth impregnated with a commercially available cleaning agent. It is used to remove dirt.

[Problem that the invention seeks to solve]

However, the method of wiping with a cloth impregnated with a commercially available detergent as described above has the following problems.

(1) Commercially available detergents are for washing clothes and tableware, so even if they have cleaning properties, they do not have antistatic properties, and although they may be able to remove stains temporarily, they do not have antistatic properties. It gets dirty.

(2) The cleaning agent drips and stains the surrounding area, or remains on the surface and impairs the original performance of the article.

[Means for solving problems]

The present invention is intended to solve the above problems, and improves cleanliness and antistatic properties by impregnating an absorbent material with a liquid composition containing a specific cationic surfactant and a specific amine oxide. The purpose of the present invention is to provide a cleaning material that is easy to use, highly effective in removing dirt and preventing re-deposition.

The present invention provides a liquid solution containing 0.01 to 10% of a cationic surfactant represented by the general formula (1) and 0.01 to 10% of an amine oxide represented by the general formula (■). This is a cleaning material characterized by impregnating an absorbent material with a composition.

In addition, as the hydroxyalkyl group, hydroxyethyl group, hydroxypropyl group, dihydroxypropyl group,
Examples include hydroxybutyl group, and hydroxyethyl group is particularly preferred. Examples of the halogen atom represented by X include chlorine, bromine, and iodine, with chlorine being particularly preferred.

In general formulas (1) and (H), the number of carbon atoms in R1-R7 is limited because if the number of carbon atoms in R1 and R5 is less than 8, cleanliness is insufficient, and the number of carbon atoms in R1-R7 is limited. If it exceeds 24, it becomes solid and has low solubility in water, solvents, etc., making it difficult to impregnate absorbent materials and resulting in insufficient cleanliness. Further, n is limited because if n exceeds 3, the antistatic effect will deteriorate.

The liquid composition used in the present invention is a composition containing a cationic surfactant represented by general formula (1) and an amine oxide represented by general formula (If) at a concentration of 0.01 to 10% by weight, respectively. It is. The reason why these two components are essential in the present invention is that if only one of the components is included, either the detergency or the antistatic property will be lacking.

The concentration of the cationic surfactant and amine oxide is limited because if it is less than 0.01% by weight, either the detergency or antistatic property will be significantly inferior, and if it exceeds 10% by weight, the components of the liquid composition will be degraded. This is because it remains on cleaned surfaces. The preferred content of these components is 0.1 to 5% by weight.

The liquid composition used in the present invention may contain a solvent such as water and other components in addition to the above two components.

In particular, it is preferable to form an aqueous solution of the cationic surfactant and amine oxide.

In this case, the cationic surfactant and amine oxide are
A liquid composition is prepared by dissolving it in water. At this time, a compatible low boiling point solvent such as methanol, ethanol, propatool, isopropyl acetate, acetone, or methyl acetate is added to speed up the drying after cleaning. can be added. Preferred solvents are ethanol and isopropanol.

In addition, the liquid composition may contain polyoxyethylene alkyl ether, polyoxyethylene alkyl phenyl ether, polyoxyethylene fatty acid ester, polyoxyethylene sorbitan fatty acid ester, sorbitan fatty acid ester, fatty acid alkanolamide, etc. in order to enhance the cleaning power. Amphoteric surfactants such as nonionic surfactants, carboxybetaine, sulfobetaine, and amino acids may be added, as well as viscosity modifiers, antifoaming agents, leveling agents, polishing agents, colorants, fragrances, etc. It's okay.

The absorbent material used in the present invention is a material that has flexibility so that it can be impregnated with the above-mentioned liquid composition and can wipe uneven surfaces.

For example, paper, nonwoven fabrics, woven fabrics, felt, etc. made from pulp, rayon, cotton, wool, nylon, Tetron, acrylic, etc., as well as leather, urethane foam,
Examples include foamed materials such as foam rubber. A cleaning material is manufactured by impregnating an absorbent material with this liquid composition.

The cleaning material of the present invention is obtained by impregnating these absorbent materials with the liquid composition. The amount of the liquid composition impregnated is not particularly limited, but the amount of the liquid composition is 0.5 to 1 g per 1 g of the porous material.
5g is sufficient. In this case, 5g of liquid composition is approximately 1m
2 surfaces can be cleaned.

Examples of methods for impregnating the absorbent material with the liquid composition include a method of immersing the absorbent material in a liquid composite acid, and a method of injecting or spraying the liquid composition into the absorbent material.

A specific method for manufacturing a cleaning material product includes, for example, inserting an absorbent material into a bag made of an impermeable film with one side open, injecting a liquid composition, and sealing the bag.

When this product is used, it is opened and the absorbent material containing the liquid composition is removed and used. Another example is a method in which the absorbent material is stored in a cylinder, a liquid composition is injected into the cylinder, and the cylinder is covered. At this time, if one end of the absorbent material is fixed, it will not stick to your hands during use. This cleaning material product is suitable for repeated use.

The cleaning material of the present invention removes dirt from the surface to be cleaned by bringing the absorbent material impregnated with the liquid composition into contact with the surface to be cleaned and wiping or rubbing it, and also prevents dirt from re-adhering due to its antistatic effect. to prevent

This makes it possible to clean even electrical products that dislike moisture, and prevents stains due to dripping.
