환경친화형 경량 건축 마감재 조성물 및 이의 제조방법{ECO-FRIENDLY LIGHT WEIGHT FINISHING MATERIAL COMPOSITION AND MANUFACTURING METHOD THEREOF}TECHNICAL FIELD [0001] The present invention relates to an environmentally friendly lightweight construction finish composition and a method for manufacturing the same,

본 발명은 경량 건축 마감재 조성물 및 이의 제조방법에 관한 것으로, 더욱 상세하게는 기능성, 강도 및 내구성이 우수한 경량 건축 마감재 조성물, 유동성, 접착력, 기능성, 내산성, 내열성 및 내구성이 우수한 경량 결합재를 사용함으로써 강도, 접착력, 기능성 및 내구성이 우수한 환경친화형 경량 건축 마감재 조성물 및 이의 제조방법에 관한 것이다.More particularly, the present invention relates to a lightweight construction finishing composition and a method of manufacturing the same. More particularly, the present invention relates to a lightweight building finishing composition having excellent functionality, strength and durability, and a lightweight construction material having excellent flowability, adhesive strength, functionality, acid resistance, heat resistance and durability, , An adhesive strength, a functionality and a durability, and a method for manufacturing the same.

일반적으로 건축 구조물 시공 시에 구조적으로 안정한 콘크리트 시공을 하고 있으며, 건축 구조물의 보호와 미관을 향상시키기 위해 마감재로서 수성 혹은 유성도료와 같은 화학제품인 합성수지 도료를 사용하고 있다. 상기 마감재로 사용되는 대부분의 건축용 도료는 유기화합물로 이루어져 있어 솔벤트의 냄새, 즉 휘발성 유기화합물(VOCs; Volatile Organic Compounds)에 의한 환경오염문제가 심각할 뿐만 아니라, 5 ∼ 7년이 경과한 후에는 도료에 포함되어 있는 유기화합물의 분해가 시작되어 재도장을 실시해야 하는 문제가 있었다. 특히, 콘크리트 바닥과 벽체에서 방출되는 시멘트의 독성과 내부 마감재로 사용되는 각종 건축용 도료, 벽지 등의 화학제품뿐만 아니라, 목재가구, 장식용품, 실내의 커튼이나 카페트 등의 화학제품에서 지속적으로 방출되는 벤젠, 톨루엔, 크실렌 및 포름알데히드 등의 성분을 포함하는 VOCs 및 중금속은 전신마비, 호흡기 질환, 두통, 알레르기 등을 유발시키는 문제점을 내포하고 있다. Generally, the concrete construction is structurally stable at the construction of the building structure. In order to improve the protection and beauty of the building structure, synthetic resin paint such as aqueous or oil paint is used as the finishing material. Since most architectural paints used as the finishing materials are made of organic compounds, there is a serious problem of environmental pollution caused by the smell of the solvent, that is, volatile organic compounds (VOCs), and after 5 to 7 years have elapsed The decomposition of the organic compound contained in the paint starts and there is a problem that the paint must be repainted. Especially, it is widely used for chemical products such as architectural coatings and wallpaper, which are used as interior finishing materials and toxic of cement released from concrete floors and walls, as well as chemical products such as wood furniture, decorative articles and indoor curtains and carpets. VOCs and heavy metals including components such as benzene, toluene, xylene and formaldehyde have problems causing general paralysis, respiratory diseases, headache, allergies and the like.

한편, 건물의 실내의 바닥이나 벽면에는 콘크리트로 이루어진 표면이 외부로 노출되지 않도록 마감재가 설치된다. 이러한 마감재는 금속, 석재나 목재를 이용하여 제조되는데, 금속재질의 마감재는 화재 시 화염과 유독가스를 발생시키지 않는 이점이 있으나 단열성능 및 차음성능이 부족하다는 단점이 있고, 석재재질의 마감재는 화재 시 화염과 유독가스를 발생시키지 않는 이점이 있으나 가공 및 시공이 어렵고 제조비용이 비교적 큰 단점이 있으며, 목재재질의 마감재는 제조비용이 금속재질이나 석재재질의 마감재에 비하여 적어 비교적 경제적인 이점이 있으나 강도가 취약하고 화재 시 화염과 유독가스를 발생시키며 습기에 노출되는 경우 내구성이 저하되는 단점이 있다.On the other hand, the floor or wall of the building is provided with a finishing material so that the surface of the concrete is not exposed to the outside. Such a finishing material is manufactured using metal, stone or wood. Finishing material of metal has an advantage of not generating flame and toxic gas in case of fire but has a disadvantage of insufficient heat insulation performance and sound insulation performance, and the finishing material of stone material is fire There is a disadvantage in that it does not generate flame and toxic gas, but it has a disadvantage that it is difficult to process and construct and the manufacturing cost is comparatively large, and the finishing material of wood material has a relatively economical advantage because the manufacturing cost is lower than that of metal material or stone material The strength is weak, the flame and toxic gas are generated in case of fire, and the durability is degraded when exposed to moisture.
