It relates to a method for producing herbal sand.

일반적으로 사람이 거주하는 주택이나 건물을 건축하기 위해서는 철근과 콘 크리트를 이용하여 시공하게 된다.In general, in order to build a house or building inhabited by humans, construction is performed using rebar and concrete.

즉, 내부 골조로 철근을 이용하고 상기 철근 구조물에 콘크리트를 양생하여 주택을 시공하게 된다. That is, the housing is constructed by using reinforcing bars as internal frames and curing concrete in the reinforcing structures.

그런데, 최근에는 주택이나 건물 등을 새로 지을 때 사용되는 건축자재 등에서 나오는 유해물질로 인해 거주자들이 느끼는 불쾌감, 즉 새집 증후군이 증가하고 있는 실정이다.However, recently, the discomfort that residents feel due to harmful materials from building materials used to build a house or a building, ie, a new house syndrome, is increasing.

이러한 새집 증후군을 발생시키는 유해물질은 벤젠, 톨루엔, 아세톤, 스틸렌, 포름알데히드 등의 발암물질을 포함하고 있으며 암모니아, 라돈, 석면, 일산화탄소, 질소산화물, 오존, 미세먼지, 부유세균 등과 같은 오염물질도 시공시에 추가적으로 발생하게 된다.Hazardous substances that cause sick house syndrome include carcinogens such as benzene, toluene, acetone, styrene, and formaldehyde. It occurs additionally during construction.

또한, 전술한 오염물질에 단기간 노출되게 되면 두통, 눈,목,코의 자극, 기침, 가려움증, 현기증, 피로감, 집중력저하 등의 증상이 나타날 수 있으며, 장기간 노출되게 되면 호흡기 질환, 심장병, 암 등의 질병이 나타날 수 있다.In addition, short-term exposure to the above-mentioned contaminants may cause symptoms such as headache, eyes, throat, nose irritation, coughing, itching, dizziness, fatigue, decreased concentration, and long-term exposure may cause respiratory disease, heart disease, cancer, etc. May appear.

In the case of the panels, such as the insulation, various boards or tiles, there has been a problem of having to bear additional costs. As the adhesive is attached to the wall using a chemical adhesive, there is a problem in that the use of environmentally friendly materials is colorless due to various chemicals generated from the chemical adhesive.

또한, 입주전 보일러를 통해 실내의 온도를 상승시켜 바닥재 또는 벽 등에 포함되어 있는 유해물질을 제거하는 방법을 사용하고 있으나, 이러한 방법으로는 유해무질을 완벽하게 제거하는데 한계가 있는 실정이었다.In addition, the method of removing the harmful substances contained in the flooring or the wall by raising the temperature of the room through the boiler before moving in, but this method was limited to completely remove the harmful substances.

따라서, 본 발명의 목적은 완전건조상태의 모래에 허브정유를 도포하여 흡착시킨 후 벽돌, 콘크리트, 시멘트몰탈 등의 건축용 시멘트 제품에 함유시켜 완공된 건축물에서 발생되는 다양한 유해물질을 효과적으로 탈취함으로써 주거환경을 개선시킬 수 있도록 한 허브샌드의 제조방법을 제공하는 것이다.Therefore, the object of the present invention is to apply the herbal essential oil to the sand in a completely dry state, and then adsorbed in the building cement products, such as brick, concrete, cement mortar, effectively deodorizes various harmful substances generated in the completed building residential environment It is to provide a method of manufacturing a herbal sand to improve the.
