Description

  The present invention relates to a polishing tool for protecting a painted surface and a polishing method using the same.

Conventionally, various polishing agents (waxes) have been used to protect the painted surface of automobiles. As such a polishing agent, there is known a drive light type polishing agent that is simply applied to a painted surface of an automobile and does not require wiping. Examples of such a polishing agent include 1-10% by weight of water-soluble polymers such as polyacrylamide, polyacrylic acid, and sodium polyacrylate, 0.1-10% by weight of waxes, and 0.1-10% of silicones. There has been proposed a paint surface polishing agent containing wt% as an aqueous emulsion (see, for example, Patent Document 1).
Japanese Patent No. 3011882

  However, although the polishing agent as in Patent Document 1 can achieve the effect of polishing, it is an aqueous emulsion, so that it has insufficient cleaning properties against lipophilic dirt and polishing properties for polishing the coated surface.

  On the other hand, in order to improve the cleaning and polishing properties, when an organic solvent is blended with the polishing agent and the polishing agent is applied with a cotton towel, the polishing agent is applied to the painted surface. The organic solvent remains on the painted surface as well as the towel together with the glossing component. For this reason, if the coating operation is continued as it is, a part of the polishing component once applied to the painted surface is held in the coating cloth together with the organic solvent, and it is difficult to uniformly apply the polishing agent. .

  Accordingly, an object of the present invention is to provide a polishing tool with improved cleaning properties and polishing properties and a polishing method using the same.

  The polishing tool of the present invention includes a polishing agent containing an organic solvent, a polishing component, an abrasive and an organic powder, and a coating cloth made of microfiber for applying the polishing agent. It is characterized by.

  In the polishing tool of the present invention, it is preferable that the polishing agent is in a paste form.

  In the polishing tool of the present invention, it is preferable that the polishing agent is liquid.

  Further, the polishing method of the present invention is characterized by comprising a step of applying the polishing agent to a painted surface by the application cloth using the polishing tool.

  In the polishing tool of the present invention, since the polishing agent contains an organic solvent, the cleaning property of the painted surface can be improved, and the polishing agent contains an abrasive, so Abrasiveness can be improved.

  In the polishing tool of the present invention, the coating cloth is made of microfiber, and the organic solvent is easily held in the coating cloth. Therefore, the polishing component is applied while holding the organic solvent in the coating cloth. Can be applied to the surface. Therefore, it is possible to improve the uniformity of applying the polish on the painted surface.

  The polishing tool of the present invention includes a polishing agent and a coating cloth made of microfiber for applying the polishing agent.

  The polishing agent of the present invention contains an organic solvent, a polishing component, an abrasive and an organic powder.

  Examples of the organic solvent include saturated aliphatic hydrocarbon solvents such as normal paraffin (eg, nonane, decane, dodecane, etc.), isoparaffin, naphthene, etc., petroleum oils such as kerosene, solvent naphtha, stocked solvent, and mineral terpenes. Aliphatic solvents such as terpene solvents such as limonene, camphor oil, turpentine oil, pine oil, ethylene glycol, diethylene glycol, polyethylene glycol, propylene glycol, dipropylene glycol, tripropylene glycol, polypropylene glycol, 1,4-butanediol 1,5-pentanediol, ethylene glycol monomethyl ether, ethylene glycol monoethyl ether, ethylene glycol mono n-butyl ether, diethylene glycol Methyl ether, diethylene glycol monoethyl ether, dipropylene glycol monobutyl n- butyl ether, etc. glycol solvent such as tripropylene glycol monomethyl ether. Preferably, saturated aliphatic hydrocarbon solvents, petroleum aliphatic solvents, and terpene solvents are used. In addition, an organic solvent may be used independently and may be used together 2 or more types.

  The end point of the organic solvent in the distillation test (according to ASTM D 86) is, for example, 80 to 250 ° C, preferably 140 to 220 ° C. When the end point of the organic solvent exceeds the above-described range, the volatility of the solvent is lowered, and when applying the polish, it becomes difficult to form a uniform coating film and the workability may be lowered. On the other hand, if the end point of the organic solvent is less than the above-described range, the volatilization of the solvent is too fast and it may be difficult to spread the polish.

  The organic solvent is blended in 100 parts by weight of the polish, for example, in a blending ratio of 20 to 50 parts by weight, preferably 30 to 45 parts by weight.

  If necessary, water may be used in combination with the organic solvent. In that case, water is mix | blended in 100 weight part of polishing agents, for example in the compounding ratio of 20-50 weight part, Preferably 20-40 weight part. In addition, the mixture ratio of an organic solvent and water is 50-200 weight part of water with respect to 100 weight part of organic solvents, for example, Preferably, it is 60-150 weight part.

  The glazing component includes wax and silicone oil.

  The wax is not particularly limited. For example, petroleum waxes such as paraffin wax and microcrystalline wax, for example, plant waxes such as carnauba wax, candelilla wax, rice wax, and wood wax, such as animals such as beeswax and whale wax. Examples include natural waxes such as mineral waxes such as montan wax, ozokerite, and ceresin, and synthetic waxes such as polyethylene wax, Fischer-Tropsch wax, amide wax, and caster wax. These waxes may be used alone or in combination of two or more.

  The wax described above may have an acid value, and the wax having an acid value is neutralized by an alkali component described later to form a fatty acid soap. The fatty acid soap becomes an emulsifier, and a polish can be formed as an O / W type emulsion. Moreover, the water repellency and the glossing effect can be improved by blending the wax having no acid value.

  The dropping point of the wax (according to ASTM D 127) is, for example, 50 to 110 ° C, preferably 60 to 100 ° C. In the case of a wax having an acid value, the acid value (according to ASTM D 1386) is, for example, 70 to 230 mgKOH / g, preferably 120 to 170 mgKOH / g.

Both-end modified type in which both terminal methyl groups of dimethyl silicone are substituted with functional groups, One-end modified type in which one terminal methyl group of dimethyl silicone is substituted with functional groups, Side chain methyl groups of dimethyl silicone and both And a side-chain modified group in which the terminal methyl group is substituted with a functional group.

The viscosity of the silicone oil (kinematic viscosity: 25 ° C.) are, 10~10000mm ² / s, preferably from 10~3000mm ² / s. When the viscosity (kinematic viscosity: 25 ° C.) of the silicone oil is less than 10 mm ² / s, there arises a problem that the water repellency is lowered. Moreover, when it exceeds 10000 mm < ² > / s, the malfunction that emulsifiability and leveling property fall will arise.

Silicone oils are available as commercial products, for example, SH200 series (dimethylsilicone: manufactured by Toray Dow Corning: kinematic viscosity (25 ° C.), 10-10000 mm ² / s), SRX310 (methylphenyl silicone: Toray Dow Corning: kinematic viscosity ^{(25 ℃), 100mm 2 /} s), SH510 ( methyl-phenyl silicone: Toray Dow Corning: kinematic viscosity ^{(25 ℃), 50~2000mm 2 /} s), SH550 ( methyl phenyl silicone : Made by Toray Dow Corning: Kinematic viscosity (25 ° C), 130 mm ² / s), SH710 (Methylphenyl silicone: Made by Toray Dow Corning: Kinematic viscosity (25 ° C), 500 mm ² / s), SH702 (Methylphenyl silicone) : Toray Dow Corning: Kinematic viscosity (25 ° C ), 45 mm ² / s), SH704 (methylphenyl silicone: manufactured by Toray Dow Corning: kinematic viscosity (25 ° C.), 40 mm ² / s), SH705 (methyl phenyl silicone: manufactured by Toray Dow Corning: kinematic viscosity (25 ° C.) ), 175 mm ² / s), SH1107 (methyl hydrogen silicone: manufactured by Toray Dow Corning: kinematic viscosity (25 ° C.), 20 mm ² / s), for example, the AK series (dimethyl silicone: Asahi Kasei in the viscosity range described above)・ Product made from Wacker silicone: Kinematic viscosity (25 degreeC, 10-10000mm < ² > / s), AKF series (Dimethyl silicone: Asahi Kasei-Product made from Wacker silicone: Dynamic viscosity (25 degreeC, 100-10000mm < ² > / s), AP series ( Methyl phenyl silicone: Asahi Kasei / Wacker silicone: Dynamic Degrees ^{(25 ℃), 150~1000mm 2 /} s), AR Series (methylphenyl silicone: Asahi Kasei-Wacker silicone: kinematic viscosity ^{(25 ℃), 20~1000mm 2 /} s), AS100 ( methylphenyl silicone: Asahi & Wacker silicone: kinematic viscosity ^{(25 ℃), 100mm 2 /} s), also, for example, the viscosity range of KF96 series (dimethyl silicone: manufactured by Shin-Etsu Chemical: kinematic viscosity ^{(25 ℃), 10~10000mm 2 /} s ), KF50 series (methylphenyl silicone: manufactured by Shin-Etsu Chemical Co., Ltd .: kinematic viscosity (25 ° C.), 100 to 1000 mm ² / s), KF53 (methyl phenyl silicone: manufactured by Shin-Etsu Chemical Co., Ltd .: kinematic viscosity (25 ° C.), 170 mm ² / s), KF54 (Methylphenyl silicone: Shin-Etsu Chemical Co., Ltd .: Kinematic viscosity) ^{25 ℃), 400mm 2 / s} ), KF99 ( methylhydrogen silicone: manufactured by Shin-Etsu Chemical: kinematic viscosity ^{(25 ℃), 20mm 2 /} s), KF9901 ( methylhydrogen silicone: manufactured by Shin-Etsu Chemical: kinematic viscosity ( 25 ° C.), 20 mm ² / s) and the like.

  By preparing the polishing agent in the form of a paste, the effect of polishing can be improved. Moreover, workability | operativity can be improved by preparing in liquid state.

  In the present invention, the coating cloth is made of microfiber.

  The microfiber is formed of synthetic fiber such as polyester, nylon, polyethylene, and polyimide, for example, and is preferably formed of polyester, nylon, and polyethylene. When the microfiber is formed from a synthetic fiber, the organic solvent is easily held by the coating cloth, and thus the effect of uniformly spreading the polishing agent on the painted surface is improved.

  The fineness of the microfiber is, for example, 1 dtex or less, and preferably 0.05 to 0.50 dtex.

  The cross-sectional shape in the direction perpendicular to the longitudinal direction of the microfiber includes, for example, a circular shape or a wedge shape, and preferably a wedge shape. A coating cloth made of microfibers having a wedge-shaped cross section makes it easier to remove stains on the painted surface.

  The coating cloth from microfiber is formed, for example, as a blend of polyester / nylon or polyester / polyethylene, and the ratio thereof is, for example, 10 to 50 parts by weight of nylon, preferably 100 parts by weight of polyester. Is 20 to 45 parts by weight, or 50 to 150 parts by weight of polyethylene, preferably 50 to 100 parts by weight.

  The polishing method of the present invention is not particularly limited as long as the polishing agent is applied to the painted surface using a coating cloth made of microfiber. For example, the polishing surface is adhered to the coating cloth, and the coated surface is coated. Alternatively, for example, a polishing agent may be attached to the painted surface and then spread using a coating cloth.

  According to the polishing tool of the present invention, since the polishing agent contains an organic solvent and the coating cloth is formed of microfibers, it is possible to improve the cleanability of the painted surface. Moreover, since the polishing agent contains an abrasive, the polishability of the painted surface can be improved.

  Moreover, in the polishing tool of the present invention, the coating cloth is formed of microfibers of 1 dtex or less, preferably 0.05 to 0.50 dtex. For this reason, not only water but also organic solvents are easily held in the coating cloth, and both the water and organic solvent, which is a dispersion medium for the polishing component, are held in the coating cloth, and the polishing component is uniformly applied to the coating surface. Can be applied. That is, in application, the glossy component can be uniformly applied without excessively leaving the organic solvent on the painted surface.

  Therefore, the polishing tool of the present invention eliminates the need for wiping after spreading the polishing agent, and can be used as a drive light type polishing tool.
