Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a polishing agent composition that has good protection properties for painted surfaces, plated surfaces, metal surfaces, etc.

Machines and equipment that have painted, plated, or metal surfaces use protective agents to protect their surfaces.

A typical protective agent is called a retardant, which is used in large machinery and equipment used both inside and outside the country, such as automobiles, trains, and monorails. Although the retardant composition of the present invention can be used in these machines and devices, the following description will focus on the polishing agent for protecting painted surfaces of automobiles. Automotive polishing agents are required to have gloss and hard-to-stick effects on painted and plated surfaces, as well as protection and rust prevention effects on paint films and metal surfaces.

Another important performance is that these effects can be maintained for a long period of time even in the face of wind and rain, direct sunlight, high and low temperatures in summer and winter, etc. Furthermore, since the work steps of applying, drying, wiping, and polishing the polishing agent require a great deal of labor, each step needs to be as simple as possible. Conventionally,
Automotive polish contains about 20% wax, about 10% silicone, and the rest is a solid type consisting mainly of petroleum solvent, about 10% wax, about 10% silicone, about 1
Abrasives such as 0% talc, bentonite, perlite, and silicon dioxide, approximately 5% emulsifying surfactant, water and petroleum solvent, approximately 5% wax, approximately 5% silicone, approx. Aqueous emulsion type consisting of 10% of the above-mentioned abrasive, about 5% of emulsifier and water/petroleum solvent, about 5% of wax, about 5% of silicone, about 10% of the above-mentioned abrasive, several % of There is an oil-based liquid type that consists of a dispersant and the rest is a petroleum solvent. The waxes used here include natural wax and synthetic wax, and structurally, acid wax/ester wax, partially saponified ester wax, polyethylene wax, oxidized polyethylene wax, hard microcrystalline wax, oxidized microcrystalline wax, etc. be.

Dimethylsiloxane and various modified silicones, especially amino-modified silicones, are often used as silicones. Conventional automotive polishes have a drawback in terms of long-term sustainability, as their luster and polishing effects deteriorate due to wind and rain, direct sunlight, high and low temperatures in summer and winter, etc.

In addition, after the polishing process, the polishing agent and its base have almost no antistatic effect, so dirt, dust, fine particles, etc. adhere to it, making it difficult to see, and removing them during the next polishing process. It has the disadvantage that even a small amount of particles remaining can cause scratches on the painted surface and cause the painted surface to lose its luster and luster. In addition, most of the conventional car polishes are solid type and IJ type, but solid type polishes have poor wiping properties after application and can be wiped off with a cloth such as a towel. In some cases, the coated surface must be rubbed many times before it becomes glossy or glossy, which requires a great deal of effort.

Furthermore, when wiping and polishing with a cloth stained with polish,
The wiping and polishing process is problematic because the retardant that is not wiped off remains in the form of streaks, making it difficult to see. Moreover, the solid type has the disadvantage that it has little ability to remove stains, tar, pitch, and other dirt from painted surfaces. On the other hand, with Neritype, the wipeability is good, but since the polishing agent spreads poorly when applied, there is a tendency to apply too much polishing agent, resulting in an excessive amount of polishing agent being applied to the entire surface of the car body than necessary. As a result, when wiping and polishing work, a large amount of abrasive powder containing wax and silicone is generated, and in dry winters, these particles adhere to the polished painted surface due to electrostatic friction.
It often happens that the polishing effect is halved. Furthermore, the abrasives used in Neri type, such as talc, bentonite, perlite, and silicon dioxide, have a sharp or large particle shape and particle size, so they are good at removing stains, tar, pitch, and other stains from painted surfaces. When used on an undamaged painted surface such as a new car, it has the disadvantage of causing scratches and causing the painted surface to lose its luster and luster. The present inventors have carried out intensive research in order to improve the drawbacks of such conventional polishing agent compositions, and have found that a polishing agent composition containing a specific amide compound and crystalline zeolite has extremely excellent surface protection. Having found that this method is effective, we have developed the present invention.

That is, the present invention contains (i) 2 to 15% by weight of an amide compound represented by the following general formula (1) or {2} or a quaternized product 2 to 2 thereof, and {ii) 2 to 15% by weight of crystalline zeolite. A polish composition is provided.

As the quaternizing agent, alkyl halides or hydroxyalkyl halides having 1 to 3 carbon atoms, alkyl carboxylic acids, dialkyl sulfuric acids, etc. are used. For example, it can be easily synthesized by the reaction of jetylene triamine with acid chloride of behenic acid or the reaction of behenic acid with methyl ester using sodium melachite as a catalyst.
Examples of amide compounds include dibehenoylamide of jethylenetriamine or dibehenoylamide of (bispropylamino)methylamine obtained by a similar reaction, and quaternary amide compounds obtained by quaternizing them with dimethyl sulfate. Salts are exemplified as quaternized products. The crystalline zeolite used in the polish composition of the present invention is a natural or synthetic crystalline zeolite.

Examples of natural crystalline zeolites include the following. Namely, borofluorite, dakusite, soda fluorite, Thomson fluorite, edgington fluorite, sodalite, cancrinite, gmelinite, syabasite, erionite, ophretite, kaijuite, jismont fluorite, yugawarafutuite, kifutuite, yubafutuite, and bryustar.

). X-ray amorphous aluminum/sodium silicate is formed as the primary precipitate product in the exothermic reaction. After stirring vigorously for 1 minute, the suspension of the precipitated product is transferred to a crystallizer and kept there at an elevated temperature for crystallization (for example 2 hours at 10,000 °C).

The solution passes through the suction furnace, and the washing water that flows out is about 10 -
After post-rinsing with deionized water until it has a value, the lacquer is dried. Commercially available natural and synthetic crystalline zeolites such as detergent builders, molecular sieves, etc. can also be used in the present invention. The most preferred crystalline zeolite is a French-type synthetic zeolite. The particle size of the crystalline zeolite is preferably between 0.5 mm and 40 mm, preferably 1 mm.
