Cement, which is generally used as the main binder of cement-based ceramic building materials, is a material that creates a stable material through hydration reaction with water, and is a semi-permanent, durable material that further increases in strength over time.

However, the cement-based ceramic construction material structure deteriorates due to the use of sea sand aggregate containing salt, such as acid rain and acid gas due to environmental pollution, and as a result, the durability and stability of the cement-based ceramic construction material structure are deteriorated. .

In addition, the surface of the concrete floor in warehouses, manufacturing plants, underground parking lots, and offices is subject to repeated moving loads due to the high frequency of use by pedestrians, vehicles, and heavy equipment. This takes a lot of time and money for maintenance.

Recently, for the purpose of improving the material and environmental problems of epoxy resin-based and urethane-based floor coverings, development of various hybrid resins has been attempted to strengthen adhesion between dissimilar materials and improve physical performance. When subjected to insufficient or long-term load, it is difficult to apply in the field, such as lifting and peeling.

Meanwhile, as the importance of the environment and resources has recently emerged as an important issue, countries around the world are making great efforts and investments for efficient use and recycling of resources and environmental protection. Among them, the recycling aspect of resources includes both a solution to a resource problem and a solution to an environmental problem, so the importance is being emphasized more and more, and various efforts are being made to activate the recycling of household waste.

The low-density polyethylene is used by mixing with the polypropylene. By mixing and using the low-density polyethylene, the low-density polyethylene itself has a side branch structure, and even though radicals are generated by the radical generator, decomposition occurs unlike polypropylene. However, since the molecular weight is increased, it can be expected to maximize the foamability without lowering the molecular weight as a whole. In the present invention, the low-density polyethylene may have a weight average molecular weight of 600,000 to 800,000 g/mol, and a polyethylene having a melt index of 0.1 to 0.4 g/10 min (230° C.) may be used.

For example, as the wood powder, various types of wood powder known in the art, such as wood chips, sawdust, shavings, recycled kraft, or corrugated cardboard as well as natural wood, may be used.

In addition, the coffee grounds are called by various names such as coffee waste, coffee meal, coffee ground, etc. The coffee grounds refer to the residue left after extracting the coffee liquid from coffee beans, and the coffee foil contains not only organic matter but also abundant fiber, lignin, As it contains a large amount of various functional substances such as caffeine and polyphenol compounds, it is evaluated as one of the organic resources with high recycling value.

In the present invention, the wood flour and coffee foil may be used by being finely powdered using a grinder in order to be uniformly mixed with the finishing paint composition and applied to the floor.

Next, a wood powder mixed powder may be prepared by mixing the first naturally-dried wood powder and coffee grounds, and the wood powder mixed powder may be dried by second heating.

In the above step, wood powder mixed with wood flour and coffee meal is mixed by mixing the first naturally-dried wood flour and coffee powder to prepare a wood powder mixed powder, and heating the wood powder mixed powder at a temperature of 120 to 200° C. for 20 to 60 minutes. It may be dried so that the moisture content of the powder is 1 to 3%, and the wood powder mixed powder may be prepared by mixing wood flour and coffee powder in a weight ratio of 1:0.1 to 1 by weight.

Then, a coating-sealed wood powder mixed powder can be prepared by mixing a moisture blocking agent, a UV absorber, an organic antifouling agent and an inorganic antifouling agent with the wood powder mixed powder and drying the mixture to seal the coating.

In the above step, a moisture blocking agent, a UV absorber, an organic antifouling agent and an inorganic antifouling agent are mixed with the wood powder mixed powder, and then heated and dried at a temperature of 110 ~ 130 ° C. for 40 ~ 60 minutes.

By providing excellent water repellency, the polysiloxane can impart excellent water repellency and water repellency durability to the surface of the floor surface applied as a finishing paint.

The polysiloxane may be represented by the following [Formula 1].

As such, it means a material containing natural fullerene. Pure shungite containing more than 90% fullerene is called elite shungite or noble shungite, and pure shungite containing 60% or less fullerene is called normal shungite.

The representative functions of the Sunjit include an antioxidant function, an electromagnetic wave blocking function, a purification and decomposition function of contaminants, and a sterilization and antibacterial function. Sunjit is a powerful natural antioxidant that enhances human immunity against numerous diseases, purifies water and air by adsorbing pollutants, and has the ability to self-decompose adsorbed pollutants.

In addition, since the Sunjit has antibacterial and sterilizing properties, it has a function of removing only 99% or more of E. coli, Pseudomonas aeruginosa, Staphylococcus aureus and harmful bacteria, and has a function of blocking harmful electromagnetic waves and emitting a large amount of far infrared rays.

In addition, the cloisonne nanopowder can be manufactured by pulverizing the cloisonne so that the particle size of the cloisonne is in nanometer (nm) units. The seven gemstones may have the effect of expanding capillaries, preventing cancer, preventing dementia, and activating cells necessary for human activity.

In particular, if you look at the compound analyzed with the seven gemstones, it contains 60% or more of SiO ₂ , so it has an excellent dehumidifying effect.

The calcium carbonate (Calcium Carbonate) is used as an inorganic filler included in the finish paint, increases the apparent viscosity to increase the initial adhesion, reduces shrinkage and expansion during curing to improve workability and adhesion, heat resistance and durability of the finish paint can play a role in improving it.

The calcium carbonate (Calcium Carbonate) has the most common chemical formula CaCO ₃ among salts that exist in nature, and has various forms, such as marble, calcite, berne, limestone, chalk, ice tin (氷洲石), seashell, eggshell, Coral, etc. may exist. The calcium carbonate is generally colorless crystals or white solid, has a specific gravity of 2.93, and can be decomposed at 825° C., and when heated, carbon dioxide (CO ₂ ) is generated and quicklime can be obtained (CaCO3 → CaO + CO2 ↑) .

The calcium carbonate is inexpensive and does not have a large specific gravity, so it can be widely used in industrial fields. The calcium carbonate is limestone marble, which can be used as a main raw material for cement, a raw material for calcium oxide, and as a neutralizing agent for building materials. Wheat flour is used for white pigments and water-based paints, and precipitated calcium carbonate is used for pigments, paints, toothpaste, etc., and can also be formulated as a reinforcing agent in rubber.

The expanded graphite powder is a powder of expanded graphite, and in general, graphite is a mineral in which planar macromolecules in which 6-membered carbon atoms are infinitely connected in a plane are layered on top of each other, and its properties are good conductors of electricity, and poly Due to the layered structure of Sen, it is flexible and active, and although it is easily cleaved, it is a macromolecule and has low reactivity.

However, since graphite is only connected by van der Waals force between the carbon planes of the polycene structure, it is 35.5 nm wider than the 14.2 nm gap between carbon atoms. can In other words, while maintaining the network plane of the graphite crystal, many atoms, molecules, or ions are inserted into the gaps between the planes to create an interlayer compound.

That is, when an interlayer compound or residual compound coated with an acid such as sulfuric acid between layers of graphite is rapidly heated to a temperature close to 1000° C., the acid is vaporized to generate gas, and the interlayer of graphite is separated by several tens to hundreds by the expansion pressure of the gas. It expands into a ship, which is called expanded graphite.
