Description

Environment-friendly soluble wax composition for automatic vehicle-washing devices}

The present invention relates to an environmentally friendly water-soluble wax composition for an automatic car wash, and more particularly, an environmentally friendly water-soluble wax composition for an automatic car wash, which is composed mainly of a high melting point natural wax which is an environmentally friendly natural substance and a natural fatty acid compound derived from the natural substance. It is about.

In general, automotive varnishes can be divided into liquid, paste and solid phase, solid or paste is excellent in coating power or gloss, but there is an inconvenience to be applied to a cloth or sponge in the method of use. Conventional liquid polishes are convenient to use spray-type sprayers, but the contents are simply emulsified with silicone oil in water or a composition containing an organic solvent. There are disadvantages. Therefore, there is a need for a liquid varnish that can simultaneously increase the glossiness and use effects such as decontamination.

In addition, the conventional liquid polish for automatic car washes is composed of liquid paraffin, nonionic surfactants and purified water, and a small amount of wax (lead), liquid paraffin, nonionic surfactants, and purified water. It consists of only a small water repellent effect, and there is almost no initial gloss effect and lasting gloss effect on the painted surface of the car after the automatic car wash process.

In Korean Patent Application No. 96-61216, 0.1 to 5% by weight of wax, 0.5 to 7% by weight of silicone oil, 5 to 30% by weight of petroleum solvent, 1 to 10% by weight of alcohol solvent and 0.1 to 3% by weight of emulsifier Disclosed is a car polish composition containing. The patent selects the most suitable surfactant to increase the glossiness and maintain the emulsion stability of the wax by mixing and using wax and silicone oil as a raw material for automobile polish, and contaminants such as tar that are difficult to remove with a general solvent. Kerosene, a petroleum-based solvent, is used to remove oil, and the effect of glossiness and decontamination is excellent. In Korean Patent Application No. 96-73740, a silicone surfactant is added without using petroleum wax to easily wash and polish. The present invention discloses a cleaning and polishing composition for automobiles, which has an antistatic effect and suppresses the generation of static electricity so that dust does not adhere to the vehicle body and thus the gloss and cleanness can be maintained for a long time.

Korean Patent Application No. 2000-01363 discloses 0.1 to 8.0% by weight of one or more mixtures selected from wax compounds which give gloss and water repellency, 1.0 to 15.0% by weight of amine-modified silicone emulsion mixture, water repellency 0.5 to 25.0% by weight of one or more mixtures selected from hydrocarbon oil compounds which impart the composition, 0.5 to 20.0% by weight of one or more mixtures selected from the group of cationic and nonionic surfactants as emulsifiers, solubilization and anti-freezing A transparent liquid varnish composition for automatic car wash comprising 0.1 to 20.0% by weight of one or more mixtures selected from the group of alcoholic solvents for action and 12.0 to 97.8% by weight of purified water, the initial gloss effect and the lasting effect on the car paint surface after the polishing process. It is disclosed that there is.

However, the conventional car wash wax is an emulsion wax mainly composed of synthetic wax, liquid paraffin, nonionic surfactant and purified water, or a mixture of silicone compounds for gloss and water repellency in a small amount of wax. In most cases, it is easy to contaminate the environment after washing the car, and it is easy to separate into an emulsion state, so it is less stable and has many defects in long-term storage.

Therefore, the present invention mainly developed a water-soluble wax composition mainly composed of high melting point natural wax and natural fatty acid compound, which is an environmentally friendly substance, has less environmental pollution, excellent gloss, water repellency, corrosion protection, antifouling properties, and stable phase, and thus long-term storage. It can be stored in the freezing and winter conditions.

Accordingly, an object of the present invention is to provide an environmentally friendly water-soluble wax composition for an automatic car wash which is less environmentally polluted, has excellent gloss, water repellency, corrosion resistance, antifouling properties, and is stable for a long time.

In order to achieve the above object, an environmentally friendly water-soluble wax composition for an automatic car wash according to the present invention is 0.5 to 10.0 wt% of carnauba wax, 0.5 to 4.0 wt% of paraffin wax, 0.5 to 6.0 wt% of distearyl dimethyl ammonium chloride, and 12 carbon atoms. 0.5 to 8.0% by weight of one or more mixtures of natural fatty acid amines (compounds having an ethylene oxide (EO) addition mole number n of 2 to 10) of 18 to 0.5 to 16.0% by weight of polyhydric alcohols, and the balance includes purified water.

Looking at the present invention in more detail as follows.

In the present invention, 0.5-10.0 wt% of carnauba wax, 0.5-4.0 wt% of paraffin wax, 0.5-6.0 wt% of distearyl dimethyl ammonium chloride as emulsifier, 0.5-8.0 wt% of higher aliphatic amine EO adduct, and 0.5-8.0 polyhydric alcohols. A water-soluble wax composition for an automatic car wash containing 16.0% by weight and 55.6-97.5% by weight of purified water is provided.

Carnauba wax, the first component of the composition according to the present invention, is a wax obtained after drying the leaves of a tree called carnauba or palm copernica cerifera, which grows in the northeastern region of Brazil. It has the highest hardness among the waxes with excellent gloss. For reference, the palm Copernica cerifera: grows in tropical regions of South America, grows to about 10 meters in height, and has fan-shaped leaves. Carnauba wax is also called canaber wax, carnauba wax, brazilian wax, and the like.

Carnauba wax has T1 and T3 depending on the degree of purification. The smaller the number, the more purified. The color of the initial extraction state is a brownish green color with a slight greenish color, but the color becomes lighter as it is purified, so it is pale yellow in the case of T1. T1 is mainly used for cosmetics, printing, coatings, medicines and release agents, T3 is a general purpose grade (glossy wax, water repellents, surfactants, textile emulsions and general industrial use).

Melting point (Min. ℃): above 80 ℃

Acid Value: Min./Max .: 2/10

Ester value: 75/85

Color: Light Yellow / Dark Yellow

In the present invention, the carnauba wax is not only environmentally friendly as a natural wax compared to other synthetic waxes or petroleum waxes, but also has been proved to be excellent in its performance and is used for various purposes. In addition, compared with other natural waxes, its melting point is high, and the strength of the film after use is remarkably excellent, and its performance is maintained as it is even at high and low temperatures. Therefore, in the present invention, the carnauba wax is used as a main component thereof in an amount of 0.5 to 10% by weight. In this case, when the amount exceeds 10% by weight, emulsification is difficult and stability is lowered.

Paraffin wax, the second component, is a milky white wax that is a mixture of solid saturated hydrocarbons. The melting point varies depending on the grade, but is generally about 43-63 ℃, and its specific gravity is about 0.82. It is a neutral supplement with good water repellency and excellent stability against heat, sunlight and drugs.

The paraffin wax in the present invention is utilized as a gloss and water repellent aid, and to maintain stability against other drugs or sunlight. In the present invention, it is preferable to use a minimum amount of paraffin wax for environmentally friendly water-soluble wax, and 0.5 to 4.0% by weight is used.

The third component uses distearyl dimethyl ammonium chloride, an off-white cationic surfactant, as the emulsifier. to be. Generally 70% or more of solid content, amine free (Free amine), the salt is about 2%, pH is 6.0-8.0. In the present invention, the distearyl dimethyl ammonium chloride is 0.5 to 6.0% by weight for stable emulsification and water repellency, antistatic function, antifouling and corrosion protection. At this time, when the amount of use exceeds 6.0% by weight, the viscosity rises and the emulsion stability tends to be low.

The fourth component uses, as another emulsifier, a mixture of at least one of natural fatty acid amines having 12 to 18 carbon atoms (compounds having an ethylene oxide (EO) addition mole number n of 2 to 10) as nonionic surfactants. Representative stearyl amines ((EO) ₂ ) are characterized by a white solid appearance and a HLB 4.9 color of G, 5max. pH is 8-10 and specific gravity is about 0.89. Generally used as emulsifiers, antistatic agents, corrosion inhibitors and the like. Other preferred fatty acid amines include lauryl amine and the like.

In the present invention, without using a petroleum-based nonionic surfactant as another emulsifier, by using at least one mixture of fatty acid amine EO adducts, which are natural fatty acid derivatives, it is added to have emulsification and solubility, and its own anti-corrosion function and In consideration of the antistatic function, 0.5 to 8.0% by weight was blended. If the amount of the fatty acid amine used is less than 0.5% by weight, the emulsifying ability, anti-corrosion function, and antistatic ability of the wax is lowered, and if it exceeds 8.0% by weight, emulsification tends to be difficult.

The polyhydric alcohol as the fifth component is used by mixing one or more of ethylene glycol and propylene glycol having excellent solubility and anti-freezing function, and the amount thereof is 0.5 to 16.0% by weight so as to keep the freezing temperature of the wax below zero. It was.

According to the present invention, 100% by weight of the purified water is mixed with the remaining (balanced) components together with the above components. As described above, the composition of the present invention is an environmentally friendly material having high melting point natural wax and natural fatty acid compound, which are environmentally friendly materials, and excellent in gloss, water repellency, stability, and the like.
