TECHNICAL FIELD [0001] The present invention relates to an eco-friendly floor coating agent having excellent lightness and lightness persistence, and a method for producing the same. BACKGROUND ART < RTI ID = 0.0 >

The present invention relates to an eco-friendly floor coating agent having excellent lightness and lightness persistence, and more particularly, to an eco-friendly floor coating agent having excellent lightness and lightness persistence, and more particularly, To an eco-friendly floor coating agent having excellent durability, abrasion resistance, gloss and the like, and excellent brightness and persistence of light which can maintain an excellent brightness even after a lapse of time due to excellent lightness persistence as well as initial lightness, and a manufacturing method thereof.

Recently, the development goal of domestic and foreign coating materials for flooring is to develop high-performance and high-function coating agents having various uses and characteristics in consideration of the environment. Among these coatings, water-based coatings have been used for internal purposes since their physical properties have fallen to date. However, the use of water-based coatings has been increasing in the paint and coating industries as domestic regulations have been tightened due to the enforcement of environmental regulations.

However, water used in water-based coatings has a large surface tension and a high latent heat of vaporization, which is affected by the climatic conditions during film formation and is poor in drying characteristics. Further, water-borne coatings have poor ductility and stain resistance , A hydrophilic substance such as a carboxy group or polyethylene oxide is contained in the structure to neutralize it, and the neutralized salt remains in the film, which causes a problem that the water resistance, the alkali resistance and the weather resistance are deteriorated.

On the other hand, since the tile is characterized by excellent durability, water resistance and abrasion resistance, it is widely used not only as a ceiling of a ceiling, a floor and a wall, but also as a decorative material by adding various shapes.

Generally, tiles are used in business areas such as kitchens, toilets, verandas, bathrooms, saunas, and steam rooms where a hygienic environment is required due to the above characteristics. These tiles are made of marble, polyvinyl chloride , Porcelain, fraud, synthetic resin, glass, etc., various kinds of materials have been proposed and used in various ways depending on the material and the intended use.

However, conventional floor coating agents used for tiles such as polyvinyl chloride (PVC) resin are generally applied by using the wax itself as a coating agent several times, and the bottom coating agent used for the tile is a coating time for coating The long time is consumed and it is difficult to obtain the desired light intensity or hardness, so that a problem of high frequency of retry has occurred, which causes a problem of an increase in the process cost.

In addition, the floor coating agent applied to a conventional tile is easily peeled off in a short period of time and is deteriorated due to the peeling phenomenon, resulting in poor durability and being susceptible to stains and abrasion. In addition, There is a problem that repetitive coating is frequently performed due to poor sustainability.

The floor coating agent according to the present invention is environmentally friendly and can adsorb and remove contaminants infiltrated on the floor surface and simultaneously enhance the durability, abrasion resistance, gloss and the like of the bottom surface by strengthening the surface of the gloss agent applied. When the bottom surface is cleaned by rubbing, the thermoplastic resin is melted by frictional heat between the pad and the bottom surface, thereby easily restoring the damaged portion or voids of the bottom surface and increasing the hardness of the bottom surface.

In addition, since the floor coating agent according to the present invention has excellent brightness persistence as well as initial brightness, excellent brightness can be maintained even after a lapse of time, and since the compositions are uniformly dispersed, When working with a coating agent, it is possible to solve the inconvenience of dispersing or stirring the floor coating agent in use.

Phosphoric acid acts as an inorganic acid to promote the reaction of anhydrous sodium citrate, ammonium bicarbonate and the like, and the phosphoric acid may be contained in an amount of 3 to 5% by weight in the entire composition of the floor coating composition.

In the present invention, when the amount of the phosphoric acid is less than 3% by weight, the anhydrous sodium citrate, ammonium hydrogen carbonate, and the like may not sufficiently react to form a coating layer on the bottom surface. The physical properties of the floor coating agent may be impaired due to the unevenness of relative compositional content, which may interfere with the formation of the coating layer.

In the eco-friendly floor coating agent according to the present invention, phosphoric acid may be preferably used. In addition to the above-mentioned phosphoric acid, it is also possible to use a coating composition containing hydrochloric acid, nitric acid, sulfuric acid, boric acid and perchloric acid One or more inorganic acids selected from the group consisting of

When the anhydrous sodium citrate is contained in an amount less than 0.5% by weight, it is difficult to uniformly disperse the compositions, There is a problem of deteriorating the physical properties of the floor coating due to the unevenness of relative compositional contents of the compositions other than anhydrous sodium citrate. Lt; / RTI >

If the amount of the ammonium hydrogen carbonate is less than 1 wt%, the content of ammonium hydrogen carbonate is too low, It is difficult to control the pH of the coating solution. When the content of the surfactant is more than 3% by weight, the storage stability of the floor coating agent may be deteriorated due to the progress of gelation.

In the eco-friendly floor coating material according to the present invention, ammonium hydrogen carbonate may be preferably used. In addition to the ammonium hydrogen carbonate, at least one selected from the group consisting of Ammonium carbonate, Sodium bicarbonate, Sodium carbonate, Sodium bicarbonate and Potassium bicarbonate may be used.

When the thermoplastic resin is contained in an amount of less than 10% by weight, the resin content is too small, When the bottom surface coated with the floor coating material according to the present invention is cleaned by friction using a pad or the like, the content of the resin is not sufficient and the light persistence to the damaged portion or void portion of the bottom surface is not sufficient Problems may occur. When it is contained in an amount exceeding 20% by weight, the components of relatively different compositions are reduced and the overall physical properties are not balanced, so that the overall physical properties of the prepared floor coating film may be deteriorated.

In the eco-friendly floor coating agent according to the present invention, a floor coating agent can be produced by using a thermoplastic resin. In the eco-friendly floor coating agent according to the present invention, By melting the thermoplastic resin, a part of the damaged bottom surface or bottom surface void is filled with the thermoplastic resin, and the effect of restoring the gloss of the bottom surface as in the case of the initial coating can be exhibited.

In the present invention, the distilled water may contain residual amount to satisfy 100 wt% of the total amount of the bottom coating agent. If the content of the distilled water is small, the thickness of the bottom coating agent may be uneven or the workability may be poor. When the content of the distilled water is excessively large, when the floor coating according to the present invention is applied to the bottom surface, the coating time may be delayed and the coating layer may not be formed properly.
