Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to polish compositions. In particular, the present invention relates to a polishing agent composition that has good water repellency and is extremely simple in polishing process.

Preservatives are used to protect machines and equipment that have painted, plated, or metal surfaces. A typical adhesive is called a polishing agent, and is used in large machinery used indoors and outdoors such as automobiles, trains, and mole rails.
used in equipment. The polishing agent composition of the present invention can be used in these machines and devices, but the following will mainly describe the polishing agent for protecting painted surfaces of automobiles. It is claimed to have gloss and polishing effects, as well as protection and rust prevention effects for paint films and metal surfaces. In addition, these effects last for a long time even when exposed to wind, rain, direct sunlight, high or low temperatures in summer or winter! It is an important performance to maintain lc.

Furthermore, since the work steps of applying, drying, wiping, and polishing the polishing agent require a great deal of labor, it is necessary that each step be as simple as possible.

Conventional automotive polishes are mainly solid types and neri types, and various types are known. for example,
Solid type consisting of approximately 2096 wax, approximately 10% silicone oil, and the remainder mainly petroleum solvent, approximately io* wax, approximately 10% silicone, approximately 10% talc,
Abrasives such as bentonite, perlite, and silicon dioxide,
Neri type consisting of about 51 emulsifying surfactants, water and petroleum solvents, about 5Ls of wax, about 5% silicone,
About 10 grams of the above-mentioned abrasive, about 5 grams of an aqueous emulsion type consisting of an emulsifier and water/petroleum solvent, about SL of wax, about 5 grams of silicone, about 10 grams of the above-mentioned polishing agent,
It is an oil-based liquid type that consists of several drops of dispersant and the rest is petroleum-based solvent.

The waxes used here include natural waxes and synthetic waxes, and their structures include acid waxes, ester waxes, partially saponified ester waxes, polyethylene waxes, oxidized polyethylene waxes, hard microcrystalline waxes, and oxidized microcrystalline waxes. There is.

In addition, silicone has a kinematic viscosity (25°C) of 10 to 10
It is well known that dimethylpolysiloxane of 0.00 centistokes is suitable as an additive for automotive polishes (Shin-Etsu Chemical Co., Ltd. Sales Catalog, ■

Furthermore, recently, a polishing agent containing 2 liters of 10,000 centistoke dimethylpolysiloxane and 1% by weight of 550 centistoke dimethylpolysiloxane has been proposed (Household and Automotive Chemical Substrate). Sharitize (ouseh)

However, the performance of conventional polishing agents for automobiles such as luster, luster, and water repellency deteriorates due to wind and rain, direct sunlight, high and low temperatures in summer and winter, and their long-term sustainability is limited. There is a problem with this.

In particular, the durability of gloss, polish, and water repellency is low.
The decrease in durability of Neri-type polishes is noticeable because a surfactant must be added to the rounding process used to make the W emulsion, and the addition of wax and silicone components is restricted and reduced from the standpoint of emulsion stability. be.

In addition, after the polishing process, the polishing agent and its base have almost no antistatic effect, so dirt, dust, fine particulate dirt, etc. adhere to it, which makes it difficult to see, and when the next polishing process is performed, those particles will adhere. Even a small amount of residual paint has the disadvantage of causing scratches on the painted surface and causing the painted surface to lose its luster and luster.

In addition, most of the conventional car polishes are solid type and neri type, but solid type polishes are difficult to wipe off after application, and when wiped with a towel or other cloth, it is difficult to wipe them off several times. However, if you don't rub the applied surface, it won't be shiny or glossy, which requires a lot of effort. Furthermore, when wiping or polishing with a cloth contaminated with polish, the polish that is not wiped off may remain in streaks, making it difficult to see, making it difficult to wipe or polish.
The polishing process is a problem. Moreover, the solid type has the disadvantage that it has little ability to remove stains such as stains from painted surfaces and tar and pitch. On the other hand, with the Neri type, the wipeability is good, but because the polish spreads poorly when applied, there is a tendency to apply a large amount of polish, resulting in an excessive amount of polish being applied over the entire surface of the car body. As a result, when wiping and polishing, a large amount of abrasive powder containing wax and silicone is generated.
In dry winter months, they often adhere to polished painted surfaces due to frictional static electricity, reducing the polishing effect by half.

Therefore, the present inventors conducted extensive research to improve the drawbacks of conventional polishing agent compositions, and found that by adding a specific carboxylic acid metal salt, the polishing agent composition can be used during wax application. The present invention was completed based on the discovery that it is possible to obtain a polishing agent that is extremely easy to spread and wipe off after drying.

That is, the present invention provides a polishing agent composition characterized by containing the following (→ to (d)).
