The present invention relates to a UV-coated high glossy architectural interior material and a method of manufacturing the same. More specifically, the present invention is a UV-coated high gloss architectural interior material and its preparation prepared by surface treatment, groove cutting, strength reinforcement and waterproofing, urethane coating, urethane coloring, pattern printing, UV-paint coating and delivery of ceramic boards. It relates to a manufacturing method.

Originally, a building has not only a practical aspect of stably protecting and maintaining a human living space from cold and rainy weather, but also an artistic aspect in which human aesthetic creativity is collectively expressed. There is a tendency to be emphasized more and more, the structure of the building and the development of a variety of construction materials are required accordingly.

In particular, in the case of architectural interior materials, these aesthetic aspects are more and more exhibited, but the development of materials that can satisfy the human aesthetics while having the properties that should be basically carried out as building materials such as discontinuity, water resistance, durability, etc. You can't say that you are at a satisfactory level. Conventional building materials developed as materials that meet the aesthetic sense of human beings with the properties as described above, such as wood boards, plasterboard, mineral fiber boards, natural and artificial marble and conventional tiles However, in the case of wooden boards, it is satisfactory in terms of aesthetics such as the pattern of wood, but there are disadvantages in terms of building materials such as incombustibility, water resistance, and water resistance. It is known to cause lung disease and lung cancer, and despite its advantages as a building material, its use is being banned in the world. In the case of mineral fiber board, it has a disadvantage in terms of cosmetics. And Indian marble are excellent in terms of aesthetics such as shell properties, but are expensive and have problems with hardness. In the case of existing Thais, it is produced by dipping ocher like bricks, drying them, applying ceramic or glass components, and melting them at high temperature (about 1400 ℃ or more) and baking them. The wet process delays work and has the disadvantage of being weak to heat or impact.

As a material that overcomes the disadvantages of the conventional building materials, building materials using ceramics are now widely used. Ceramic is a material produced by sintering soil raw material rich in complex compounds known as silicon oxide and silicate at high temperature. Its excellent electrical characteristics such as revoltage and dielectric loss make it widely used in the electronics industry. It is a material widely used in the construction field as a building material such as bricks, tiles, terracotta, polished building bricks, glass products, cement additives, etc. due to its excellent properties and especially absorptivity.

Ceramic board using such a ceramic is an excellent building material with a non-flammable, and strength than conventional gypsum board made of SiO _2, CaCO ₃ and asbestos board as the addition of blast furnace slag in the SiO _2, CaCO ₃ greatly improved. In particular, the added blast furnace slag is a by-product produced in a large amount by the steel industry, and its excellent thermal volume expandability enables the formation of a refractory insulating structure, which has a property that the ceramic board has better properties than the conventional asbestos board.
