Description

Technology Field

[0001] The present invention relates to a mortar having anti-condensation, antibacterial, and deodorizing functions. Specifically, the invention relates to a mortar having anti-condensation, antibacterial, and deodorizing functions that can further improve the durability of a building and maintain a healthy living space by manufacturing a mortar for finishing the interior walls of a building that includes vermiculite and perlite having antibacterial and deodorizing functions, and illite having antibacterial and deodorizing functions. Background Technology

[0002] Generally, mortar is a mixture of lime or cement and sand, mixed with water, and is used as a finishing paint for the interior walls of buildings. Insulation is a critical factor in buildings, and inadequate insulation can lead to condensation problems caused by the temperature difference between the exterior and interior. Condensation occurs primarily due to the temperature gap between the outside and inside of a building, such as during winter, and manifests as water droplets forming on ceilings, walls, and floors. Condensation is gradually increasing as buildings become larger and taller, leading to denser building materials; as underground structures become deeper, the temperature difference between the basement and the interior widens; and as living spaces are maintained at temperatures higher than necessary.

[0003] Conventionally, to prevent such condensation, insulation materials such as styrofoam or gypsum board were mainly applied to the interior walls facing the exterior. However, since the insulation does not adhere completely to the wall, the wall remains exposed to the cold, causing condensation to form between the insulation and the wall. This leads to a decrease in the performance of the insulation and can result in mold growth inside the room. Furthermore, in this case, the problem is that repairs are cumbersome as the insulation must be removed and reinstalled.

[0004] Recently, the trend has been to apply thermal insulation using paints with anti-condensation properties or functional paints with antibacterial and antifungal capabilities. However, these methods involve altering the types and content of resins and additives—the main components of standard paints—to achieve anti-condensation effects. Consequently, paints manufactured in this manner provide no assistance whatsoever in preventing condensation and have limited applications, leading to problems such as dripping of condensed water on structural surfaces, excessive moisture generation due to operating conditions, structural corrosion, and mold growth. Furthermore, since antibacterial and antifungal functional paints do not address condensation, which is the root cause of mold growth, they can only temporarily remove mold, presenting a problem where fundamental eradication is impossible.

[0014] The present invention relates to a mortar having anti-condensation, antibacterial, and deodorizing functions. By manufacturing a mortar that is a finishing material applied to the interior walls of a building using vermiculite and perlite that provide anti-condensation effects, and illite that provides deodorizing, antibacterial, and antifungal functions, the invention aims to realize a mortar having anti-condensation, antibacterial, and deodorizing functions that can be used semi-permanently.

[0015] To this end, the present invention must specifically disclose a composition added when manufacturing mortar having anti-condensation, antibacterial, and deodorizing functions, as well as a specific method for manufacturing mortar using said composition. In the detailed description to be provided below, one representative embodiment of the present invention will be presented to achieve the aforementioned technical objectives. Other embodiments that may be presented by the present invention will be described by the composition of the present invention.

[0016] Example 1 describes the composition and mixing ratio of a mortar having anti-condensation, antibacterial, and deodorizing functions, and the detailed description is as follows.

[0017] The mortar of the present invention is composed of 30% by weight of vermiculite, 25% by weight of perlite, 20% by weight of illite, 15% by weight of binder, 1% by weight of dispersant, 0.1% by weight of defoamer, 2% by weight of crack inhibitor, 0.5% by weight of antioxidant, 0.5% by weight of zinc oxide, 0.4% by weight of coloring agent, 0.5% by weight of thickener, and 5% by weight of water.

[0018] In this case, vermiculite is a mineral belonging to the monoclinic system that has a crystal structure similar to mica, also known as vermiculite, and is characterized by its grayish-white or brown color and pearly luster. Vermiculite decomposes easily in acid, has a high exchange capacity, and expands when heated. In the present invention, vermiculite serves a condensation prevention function, and it is preferable to include 30% by weight.

Additionally, it is preferable to use perlite that has been crushed to a particle size of 30 to 70 mm.

[0020] Illite is a fine mica group mineral belonging to the monoclinic system. Its chemical composition is similar to muscovite, but it contains less potassium and aluminum and more moisture. Illite is particularly effective in adsorbing heavy metals and purifying contaminated water and soil by emitting far-infrared rays; therefore, it is utilized in various fields such as livestock feed, air purification, cosmetic ingredients, and interior architectural flooring. In this invention, illite performs antibacterial and deodorizing functions and is preferably included at 20% by weight. Additionally, it is preferable to use illite in the form of crushed material with a particle size of 30 to 70 mm.

[0021] The binder is used to impart adhesive performance to the mortar, and in the present invention, an acrylic emulsion resin is used. The acrylic emulsion resin is a thermoplastic resin characterized by high mechanical strength, heat resistance, chemical resistance, and oil resistance. In the present invention, by using an acrylic emulsion resin as a binder, it is possible to manufacture an environmentally friendly and harmless mortar. At this time, it is preferable that the binder be included in an amount of 15 weight percent.

[0022] A dispersant is a substance added to prevent the aggregation of fine particles generated when large particles and aggregated particles are crushed into smaller particles and colloidal particles. Therefore, when mortar is applied to the interior walls of a building, it is possible to induce curing in the applied state without it running down. In addition, it is preferable that the dispersant be included in an amount of 1 weight percent.

[0023] Antifoaming agents are used to remove harmful bubbles, and generally, oily substances with low volatility and high diffusivity, or water-soluble surfactants, are used. In the mortar of the present invention, an antifoaming agent is included and used to maintain a smooth surface by preventing the formation of bubbles and pinholes after the mortar is applied to the interior wall of a building. At this time, it is preferable that the antifoaming agent be included in an amount of 0.1% by weight in the present invention.

[0024] The crack-preventing agent is intended to improve the flexibility of the mortar surface layer to minimize stickiness, reduce cracking or splitting of the mortar layer after curing, and simultaneously increase wear resistance. In the present invention, high-elasticity cross-linked polyurethane is used as the crack-preventing agent. High-elasticity cross-linked polyurethane possesses high elasticity, making it possible to prevent cracks and vibrations. Additionally, in the present invention, it is preferable that the crack-preventing agent be included in an amount of 2 weight percent.

[0025] The antioxidant is intended to prevent oxidation of the mortar applied to the interior walls of a building, and magnesium oxide is used in the present invention. In this case, magnesium oxide is a compound of magnesium and oxygenation that absorbs water and carbon dioxide from the air and is used as a refractory material, catalyst, adsorbent, antacid, etc. In the present invention, it is preferable that the antioxidant be included in an amount of 0.5 weight%.

[0026] Zinc oxide is a colorless crystalline powder that does not dissolve in water and is referred to as zinc oxide, zinc white, etc. Zinc oxide is a safe substance harmless to the human body and has characteristics such as high refractive index, coloring power, and high reflectivity, and in particular, possesses antiviral and deodorizing functions. In this case, it is preferable that zinc oxide be included in the present invention at 0.5% by weight.

[0027] Coloring agents are used as dyes when coloring using dyes or pigments, etc., for the purpose of making the rough color of mortar glossy, and titanium oxide is used in the present invention. At this time, it is preferable that titanium oxide is included in the present invention at 0.4 weight%.

[0028] The thickener is intended to control the physical properties of the mortar, prevent sedimentation of the residual amount after use, and increase storage stability; in the present invention, it is preferable to include 0.5 weight%.

[0029] Subsequently, the manufactured mortar is applied as a finishing treatment by airless spraying or plastering on the surface of the interior wall of a building, that is, the concrete surface before finishing work. At this time, it is preferable that the thickness of the mortar layer applied and plastered on the interior wall of the building be 2 to 3 mm. The mortar of the present invention can exhibit excellent frictional force even without forming a thick layer, and it is possible to increase smoothness by preventing air bubbles from forming in the coating layer.

[0030] FIGS. 1 and 2 are test reports on the deodorization rate of a mortar having anti-condensation, antibacterial, and deodorizing functions according to the present invention. As shown in FIGS. 1 and 2, it can be confirmed that the mortar of the present invention exhibits a high deodorization rate. More specifically, FIGS. 1 and 2 show the deodorization rate measured over time after injecting approximately 1.5 L of ammonia (NH₃) gas at a concentration of 100 μg / mL into the mortar according to the present invention. As can be seen from the test report, it can be confirmed that the mortar of the present invention exhibits a deodorization rate of 98% as the test time gradually progresses.
