DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention has a creamy form, and is applied to a painted surface of an automobile or the like to form a coating film on the surface, and the coated surface has gloss, water repellency and slipperiness. The present invention relates to an applied paint surface polishing agent.

[0002]

2. Description of the Related Art Painted surfaces of automobiles are constantly exposed to dust, dust, exhaust gas, acid rain, sunlight, and the like in a natural environment, which causes problems such as contamination and loss of luster on the painted surface. . Therefore, various polishing agents (waxes) have been used to prevent the removal of such dirt and the deterioration of the painted surface, and to protect the painted surface.

[0003] As such a wax dosage form, a wax component such as carnauba wax or paraffin wax and a silicone oil are dissolved in a petroleum solvent such as mineral terpene or kerosene under heating, and cooled to solidify. In addition to those called solid waxes, a petroleum solvent in which a wax component is dissolved and water containing a water-soluble component are emulsified with various surfactants and thickeners, and the mixture is prepared into a paste. There are kneaded wax and liquid wax prepared in liquid form. In addition, for the semi-milled or liquid form, an inorganic or organic fine powder is blended for the purpose of improving the cleaner effect and reducing the work of wiping excess wax. There are also things.

By the way, as a method of applying such a wax to a painted surface of an automobile or the like, the wax is usually applied to the painted surface using a sponge, and when the petroleum-based solvent is volatilized and the coating film is dried, the wax is dried. A method has been adopted in which excess wax is wiped off with a rag or the like. However, such a method of using a wax requires a three-step work procedure of application of the wax → drying → wiping.
It takes a lot of time and effort to wax one car, and the wiping operation is extremely troublesome.

In addition, the petroleum solvents commonly used for the above three types of waxes usually have a boiling point of 1%.
It is volatile at 50-250 ° C and has an aniline point of 4
An aliphatic hydrocarbon solvent at 0 ° C or higher, and the coating film that forms the painted surface of automobiles is generally sensitive to such petroleum solvents. However, if the working method during waxing is incorrect, this petroleum-based solvent may remain on the painted surface and cause spots and swelling, and people with sensitive skin may also suffer from rough hands. Become.

Further, the petroleum-based solvent has a peculiar odor, so that it may be necessary to mask it with a fragrance. In addition, inorganic or organic fine powder compounded to facilitate the wiping operation may be used. There is also a problem that the gap in the body of the automobile or the window washer hole is clogged, which impairs the aesthetic appearance of the automobile and impairs the function of the window washer.

[0007]

The inventors of the present invention have conceived a method of using such a conventional wax which requires operations such as coating, drying and wiping, and various problems caused by a petroleum solvent as a component. As a result of intensive studies on the method of solving the problem, the composition obtained by mixing the water-soluble polymer and the waxes and silicones in water and dispersing it as an aqueous emulsion does not require wiping work, and It has been found that a coating film having excellent gloss, water repellency and slipperiness can be formed, and the present invention has been completed.

Accordingly, an object of the present invention is to eliminate the conventional wiping operation of a wax and to form a coating film only by a coating operation. Painted surface that has no adverse effect on paint film and human skin, is odorless, and has excellent gloss, water repellency, slipperiness, etc., without impairing the appearance of the painted surface of the car after work To provide a polishing agent.

[0009]

That is, the present invention provides a creamy composition comprising 1 to 10% by weight of a water-soluble polymer, 0.1 to 10% by weight of waxes and 0.1 to 10% by weight of silicones as active ingredients. It is a paint surface polisher contained as an aqueous emulsion.

The water-soluble polymer used in the present invention includes:
Basically, it may be a polymer having solubility in water, for example, guar gum, agar, gum arabic, plant-based polymer such as starch, and microbial polymer such as xanthan gum,
Gelatin, animal polymers such as casein, starch, guar gum, cellulose, semi-synthetic polymers consisting of derivatives such as methylation and carboxymethylation of alginic acid and the like, vinyls such as poval, acrylics such as polyacrylamide,
Other synthetic polymers, such as polyethylene oxide, and various things such as inorganic polymers such as veegum, bentonite, and the like, but preferably polyacrylamide,
Polyacrylic acid or sodium polyacrylate is more preferably polyacrylamide because it can be easily added to water together with waxes and silicones to increase the volume to form a creamy aqueous emulsion. One of these aqueous polymers can be used alone, or two or more of them can be used as a mixture.

Examples of the waxes used in the present invention include natural or synthetic waxes such as carnauba wax, paraffin wax, montan wax and polyethylene wax conventionally used as a polishing component in this type of polishing agent. Carnauba wax is preferred because it gives a transparent glossiness. As for silicones, various modified silicones, epoxy-modified silicones, polyether-modified silicones, and alkyl-modified silicones, such as dimethyl silicone, which has been conventionally used in this type of polishing agent, are mentioned. From the viewpoint, dimethyl silicone is preferred, and these silicones and silicones are preferably used as emulsions.

The proportion of the main component of the polishing composition of the present invention is 1 to 10% by weight, preferably 2 to 10% by weight, of the aqueous polymer.
5% by weight, waxes 0.1 to 10% by weight, preferably 0.1 to 3% by weight, and silicones 0.1 to 10% by weight, preferably 0.3 to 3% by weight. %
It is. If the blending ratio of the aqueous polymer is less than 1% by weight, the desired creamy dosage form cannot be obtained. Conversely, if it exceeds 10% by weight, the water-soluble polymer itself sticks to the painted surface. Problems arise. Also,
If the compounding ratio of the wax is less than 0.1% by weight, there is a problem that the gloss is weak and the slipperiness is deteriorated.
Conversely, if the content is more than 10% by weight, a problem arises in that the coating becomes too hot and the workability of the coating operation deteriorates. Furthermore,
If the blending ratio of the silicones is less than 0.1% by weight, there is a problem that the waxes cannot be uniformly coated on the painted surface. On the contrary, if the blending ratio is more than 10% by weight, the luster peculiar to the silicones occurs. There is a problem that the glossiness becomes uneven.

In the present invention, in addition to the above-mentioned essential components, a silicone resin may be further added for the purpose of improving the long-term water repellency. 1 to 10% by weight. Further, additives such as emulsifiers, preservatives, plasticizers, and detergents conventionally used in this type of polishing agent can be added as needed.

In order to prepare the coated surface polishing agent of the present invention,
The above-mentioned aqueous polymer, waxes and silicones are mixed with water, or mixed with water in advance and mixed in a predetermined ratio in the form of an emulsion, and mixed using a homomixer or the like until the whole becomes uniform. To form a creamy aqueous emulsion.

[0015] The method of using the polishing agent of the present invention is such that an appropriate amount of the cream-like polishing agent is taken on a suitable cloth or sponge such as a towel and applied to the painted surface of an automobile or the like, and the water is allowed to dry for a while. It only needs to be left until it evaporates.
At this time, when the water evaporates, a uniform coating film is formed on the painted surface.

The polishing agent for a painted surface of the present invention only needs to be applied to a painted surface and dried, does not require a troublesome wiping operation, and does not contain a petroleum-based solvent. There is no adverse effect on the membrane, and the waxing work can be performed comfortably without any problem of rough hands after the work or odor during the work. Furthermore, since the coated surface polishes of the present invention do not contain inorganic or organic fine powder, there is no problem such as the fine powder clinging to the car body as seen in conventional car wax, and there is no wax. Provides excellent gloss, water repellency, slipperiness and other effects on the painted surface.

[0017]

BEST MODE FOR CARRYING OUT THE INVENTION A water-soluble polymer is dissolved in water at a predetermined ratio, and a wax emulsion and a silicone emulsion prepared by previously mixing with water are blended. To prepare a coated surface polish as a creamy aqueous emulsion.

The creamy surface polisher prepared in this manner is applied to a painted surface of an automobile or the like with an appropriate cloth or sponge such as a towel or the like, and left as it is to volatilize water. Glossy, easy to painted surface,
A coating film having excellent water repellency and excellent slipperiness can be formed.

The coating film formed on the painted surface by the coated surface polishing agent of the present invention has a protective effect on the painted surface when the coating film is formed at the beginning of the coating. , Or when washed with water, the aqueous polymer in the coating film dissolves and flows away, forming a coating film of the remaining waxes and silicones, and continues to exhibit gloss, water repellency and slipperiness .
