By obtaining it, it is intended to provide an eco-friendly paint composition that can provide excellent antibacterial and antifungal properties of polyphenols, which are phytochemicals, and aromaticity, deodorization, rust prevention and insect repelling effects of coffee grounds while recycling coffee grounds, which are household waste.

A preferred embodiment according to the present invention for implementing this will be described in detail as follows.

The eco-friendly paint composition having coffee efficacy and phytochemical efficacy according to the present invention comprises a binder, thickener, dispersant and preservative in addition to inorganic substances, coffee powder and phytochemicals.

First, the inorganic material comprises at least one of ocher, white clay, black soil, red earth, and diatomaceous earth. In particular, loess is called a living organism, and a spoonful of loess contains about 200 million microorganisms. Such loess includes iron (Fe), magnesium (Mg), zinc (Zn), manganese (Mn), copper (Cu), molybdenum (Mo), selenium (Se), germanium (Ge), silicon (Si), vanadium ( V), strontium (Sr), phosphorus (P), calcium (Ca), and minerals such as chondroitin, a physiologically active substance, are contained in a lot of minerals, and when heated, bio far-infrared rays are emitted. In addition, enzymes such as catalase, diphenoloxidase, saccharase, and protease contained in loess and microorganisms beneficial to the human body decompose and mineralize organic matter to purify it. In addition to having an excellent self-cleaning effect to remove hydrogen peroxide, loess has more than 100 times the oxygen supply capacity of its own body, so it is physiologically active. In addition, loess releases and separates heavy metals, maintains temperature due to its excellent humidity control ability, and acts as electromagnetic wave blocking, antibacterial, insect repellent, physiological activity activation and detoxification.

This loess can be mixed with water and then used in the form of Jijang water by filtering the sediment.

Next, the coffee powder is obtained by processing coffee grounds, and the process of manufacturing the coffee powder according to the present invention is as follows.

Put a certain amount of coffee grounds in heated water to boil or spray hot steam to clean. In this way, water is separated from the boiled coffee grounds, which can be performed through a centrifugal solid-liquid separator.

After that, the coffee grounds from which the moisture has been separated are dried with low-temperature hot air and then pressed to separate the oil. The coffee grounds from which the oil has been separated are ground to a predetermined particle size to obtain coffee powder.

Here, polyphenols, a type of phytochemical, can be extracted from coffee grounds dried by low-temperature hot air. After mixing the dried coffee grounds and methylene chloride in detail, it is stored at room temperature for a certain period of time, and then the filtrate and coffee grounds are separated through filtration. This method was extracted a total of 3 times. Thereafter, the filtrate is collected and concentrated in a rotary concentrator under reduced pressure, and then methylene chloride is removed from the concentrate to produce polyphenol.

On the other hand, phytochemicals can be extracted from at least one of avocado and Coriander oil, which are natural plants. Avocado and coriander are known to contain phytochemicals having antibacterial properties, and when the phytochemical components are used in a paint composition, excellent antibacterial effects can be exhibited.

The avocado extract may be a water extract or an alcohol (ethanol) extract of avocado fruit. The extraction method is not particularly limited, and can be extracted by chromatography commonly used in the art, and the avocado extract is produced in powder form after drying under reduced pressure. And coriander oil can be produced by steam distillation of coriander.

The phytochemicals thus generated are preferably microencapsulated in a size of 1 to 1000 μm so that their efficacy can be sustained for a long time. Microencapsulation of these phytochemicals is performed by mixing polyvinylpyrrolidone (PVP), sodium lauryl sulfate (SLS) and phytochemicals at high speed to emulsify them, then adding chitosan solution as a capsule wall forming material to carry out a crosslinking reaction for a certain temperature and time. It can be produced by proceeding.

Next, the binder is made of at least one of a plant extract or a seaweed extract, and the plant extract is made of an undiluted solution extracted from leaves, branches and trees such as pine, cypress, fir, and Rigiteda pine. And the seaweed extract is extracted from seaweed, such as agar agar, gambler (seaweed), shiitake, shrimp, leech, or seaweed. Here, the seaweed extract is formed in the form of seaweed grass and may be used as a binder. This seaweed grass is prepared after drying seaweed, such as agar agar, and boiling it in water.

Next, the thickener is for improving coating properties by imparting viscosity to the paint, and at least one of methyl cellulose, carboxymethyl cellulose, hydroxyethyl methyl cellulose and hydroxypropyl methyl cellulose may be used.

In addition, the dispersing agent is for uniformly dispersing various components in the paint composition, and at least one of fly ash, bentonite, natural zeolite, sodium metasilicate, perlite, and calcium silicate may be used. Here, fly ash is collected by dust collectors in coal ash, and refers to spherical particles, generally with a particle diameter of 1 to 200 μm, with an average particle diameter of almost 20 μm, with silica and alumina as the main components (about 70 to 80% of both). And, by including a small amount of iron oxide and trace amounts of oxides of Mg, Ca, P, and Ti, there is an effect of further improving the thermal insulation performance of the coating film and improving durability at the same time.

Subsequently, the preservative is to increase the antiseptic power of the paint composition, and includes at least one of tocopherol and ketoeff. These preservatives can be used in conjunction with the enzyme-treated starfish extract. The enzyme-treated starfish extract has an excellent heavy metal adsorption function, and the preparation method is to decompose the protein component in the starfish with a proteolytic enzyme after adding water to the starfish, and to obtain and dry only the inorganic component calcium carbonate. .
