Description

The composition of Charcoal-Pigment for Building Interior Decoration Using the coconut milk and Its Preparation Method}

The present invention relates to a charcoal coating composition for environmentally friendly building materials and a manufacturing method thereof, and more particularly, to a charcoal coating composition for an eco-friendly building interior materials and a method for producing the coating composition is added to the natural palm liquid collected from the coconut. .

In general, color is divided into dye and pigment. The difference between these pigments and dyes is determined by whether they are chemically bonded or simply dispersed with the deposited material. In general, the distinction is that dyes do not cover the body, whereas the pigment hides the body so that the original color is retained. It can be said to represent. In addition, such pigments are added to transparent coatings such as varnishes and varnishes to form paints such as colored paints. Since paints, such as paints used for building materials, must conceal the material, the paint plays a primary role of concealing (hiding) the material, and pigments are used for this purpose. These pigments can be largely divided into main pigments and extender pigments. The main pigments are colored pigments, which are divided into inorganic pigments and organic pigments. Specifically, inorganic pigments are taken from minerals and have good concealment and dispersibility (pigment particles are evenly broken into unique particles), but some pigments contain heavy metals. Organic pigments exhibit color due to chemical synthesis, which are less concealable and dispersible, and are more expensive than inorganic pigments. In addition, weather resistance and durability alkali resistance, etc. are both inferior to inorganic pigments, but has the characteristic that the inorganic pigments have excellent brightness. The role of concealment is mainly played by the main pigment, which is considerably more expensive than the constitution pigments, so if you use a lot of the main pigment concealment power is quite good, but the price is expensive. Accordingly, the paint must be combined with PVC (Pigment Volume Concentration), that is, the total amount of pigment and the appropriate amount of the binder resin to form concealment, price, durability, etc. under optimum conditions. On the other hand, sieving pigment (filler) serves as an auxiliary role to increase the price of paint and the durability of the coating film, it is used to match the PVC with the appropriate main pigment. Therefore, the appropriate combination of main pigment and sieving pigment is improved concealment power and cost-effectiveness.

Meanwhile, as interest in living standards and health has recently increased, a well-being culture has been spreading throughout the whole life, and accordingly, air quality in indoor space (IAQ; Sick House Syndrome) is called. The importance of In door Air Quality is emerging as a new environmental issue at home and abroad. The "new house syndrome" is a type of chemical hypersensitivity and refers to a phenomenon in which specific chemical substances or various chemical substances are combined to affect the human body among indoor air pollutants. The syndrome includes environmental pollutants such as harmful substances generated from concrete, furniture, adhesives, wallpaper, paint, etc. of various buildings, electromagnetic waves, formaldehyde, other organic solvents, gases, dust, and various volatile organic compounds (VOCs). In addition, gaseous substances emitted from cosmetics, perfumes, tobacco, washed clothes, vinyl chloride, ink of printed matters, etc. have been suggested as main causes. As such, the indoor air is contaminated by various volatile organic compounds (VOCs) generated by building materials and artificial facilities such as various building materials and paints used in remodeling new buildings or old buildings. As the polluted air continues to circulate, its concentration is rapidly increasing. As an alternative, periodic ventilation is important, but above all, more active methods of removing, replacing or improving the source are required.

Recently, eco-friendly products that do not contain volatile organic compounds have appeared one after another, and furniture, adhesives, paints, and wallpaper are applied one after another, and they are applied to indoor surfaces coated with concrete, wallpaper, and paint to remove volatile organic compounds and activate the function of the human body. Various bio-materials, far infrared rays, anions, antibacterial, and deodorizing paints and coatings are used. As such, special paints with enhanced functionality have been steadily being developed. Recently, with the emphasis on living health, various paints with enhanced functionality have been developed to create a more comfortable living environment.

Charcoal is a carbon body with a porous structure with fine pores. It is excellent in moisture proofing and purification and purification of various water resources. It is widely used as a natural deodorant and humectant. Charcoal absorbs electromagnetic waves and emits far infrared rays. And it has been known that there is also the air cleaning function by the release of negative ions, the function of blocking the waves transmitted harmfully to the human body in the water veins and the electromagnetic wave blocking function of electronic products. In addition, it has near-infrared radiation, phytoncide generation, deodorization, antibacterial and antifungal functions, and is rich in minerals and used in various other fields.
