Description

Interior material and method for preparing the same The present invention relates to an interior building material and a method for manufacturing the same. More specifically, it relates to an interior building material that is beneficial to health and environmentally friendly, and a method for manufacturing the same. Natural red clay (hereinafter referred to as red clay) has been widely used in household goods, building materials, and medical products due to its excellent hygroscopic, deodorizing, and antibacterial properties. Red clay has been used as a building material for the walls, floors, and roofs of houses, and is highly effective in maintaining a comfortable indoor environment through its humidity control and antibacterial functions. In traditional architecture, red clay played an important role alongside the ondol. For example, by storing and releasing heat, it can maintain a constant indoor temperature and purify the air inside the house. In modern architecture, red clay is also garnering attention as an eco-friendly material. Buildings constructed with red clay are resistant to external temperature fluctuations, providing an indoor environment that is cool in summer and warm in winter. Furthermore, red clay improves indoor air quality by adsorbing harmful substances from the atmosphere, thereby creating a pleasant and healthy living environment. Consequently, technological development in this area is also active. For example, Korean Registered Patent No. 10-1196812 discloses a loess panel for interior use and describes technology for an interior material capable of maximizing the efficacy of loess (antibacterial, deodorizing, and humidity control). However, the aforementioned patent has limitations in providing additional performance characteristics of the interior material (e.g., durability) beyond the efficacy of loess. FIG. 1 is a cross-sectional view of an interior material according to one embodiment. FIG. 2 schematically illustrates a method for manufacturing an interior material according to one embodiment. The advantages and features of the present invention and the methods for achieving them will become clear by referring to the embodiments described below in detail together with the accompanying drawings. However, the present invention is not limited to the embodiments disclosed below but can be implemented in various different forms. To clearly explain the embodiments of the present invention, parts unrelated to the description may be omitted. Additionally, in describing the embodiments of the present invention, if it is determined that a detailed description of related known components or functions could obscure the essence or description of the present invention, such detailed description may be omitted. In describing the components in this specification, terms such as “first,” “second,” etc., may be used. These terms are intended for convenience of explanation to distinguish one component from another, and unless otherwise specifically stated, the nature, order, etc., of the components are not limited by these terms. In each step mentioned in this specification, the steps may proceed differently from the specified order unless the context clearly indicates a specific order. That is, the steps may be performed in the same order as specified, substantially simultaneously, or in the reverse order. In this specification, “and/or” may mean each of the listed components and combinations of two or more of said components. For example, “A, B and/or C” may be used with the same meaning as “at least one of A, B and C.” An interior material according to an exemplary embodiment may comprise a first layer containing clay; a second layer formed on the first layer containing loess, loess volcanic soil, and illite; and a third layer formed on the second layer containing pine resin. The interior material according to this can improve the indoor environment and contribute to health by including mineral substances that emit large amounts of negative ions and far-infrared rays. For example, it can provide a pleasant environment by absorbing and removing harmful substances in the indoor air. Referring to FIG. 1, an interior material (1) according to an exemplary embodiment may include a first layer (10) containing clay; a second layer (20) formed on the first layer containing loess, loess volcanic soil and illite; and a third layer (30) formed on the second layer containing resin. According to one embodiment, the first layer (10) may include clay. In some embodiments, the first layer (10) may include 100% clay. In some embodiments, the first layer (10) may include clay and water. The first layer (10) is composed of a clay layer or only a clay layer and water, which provides excellent thermal insulation and easy humidity control. In addition, clay is easily obtained from nature, making it eco-friendly, and does not emit volatile harmful substances, thus providing a healthy indoor environment. Clay can r
