급격한 도시화와 인구 증가로 인한 건물의 밀폐성 증가로 심각한 실내 공기 오염을 야기하고 있다. 몇몇 실내 공기오염물질 중 페인트에서 방출되는 휘발성 유기화합물(VOCs)이 주요 관심사이다. 따라서 친환경적인 페인트 제품 개발에 대한 요구가 증가하고 있다. 본 연구에서는 점토광물인 견운모를 사용하여 벽마감용 천연페인트를 제조하였다. 소규모 챔버를 사용하여 벽마감용 천연페인트에 존재하는 독성물질 확인 실험을 하였으며, 2개의 상업용 페인트와 비교 분석하였다. 총 VOC 양은 trace로 권장 실내 공기질 기준보다 낮은 것으로 나타났다. 벽마감용 천연페인트에서 톨루엔은 검출되지 않았으며 포름알데히드가 trace 레벨로 측정되었다. 독성지수 분석결과 2가지 친환경 상업용 페인트와 비교하여 본 연구에서 개발된 천연페인트가 낮은 유해물질 방출을 나타내었다. 건축자재등급 실험에서 벽마감용 천연페인트가 1등급으로 분류되었다. 이상의 연구결과에서 나타난 바와 같이 벽마감용 천연페인트의 주성분으로 견운모를 사용하는 것이 실내 공기질을 관리하는데 유용할 것이라 판단된다.

Abstract ▼ AI-Helper

Due to the rapid urbanization and increased population, there is an increase in airtight nature of buildings which causes serious indoor air pollution. Among several indoor air pollutants, volatile organic compounds (VOCs) emitted from paint are of major concern. Therefore, there is an urge for the development of environmental friendly paint products. In this wok, a natural wall paint (NWP) was prepared by utilizing a natural clay material "sericite" as a main component. A small chamber test was carried out to identify the toxic substances release from NWP and the results were compared with two eco-friendly commercial paints. The total VOCs were detected in trace level inside the test chamber and their concentrations were below the recommended indoor air quality standards. Toluene was not detected for NWP, whereas formaldehyde was observed in trace level. The toxicity index results were compared with two commercial paints and found that NWP exhibited less harmful gas emission. Based on certification rating of building materials, NWP can be classified as the first grade of building materials. Due to the above advantages, the use of sericite as a major component in NWP will be a useful technique to maintain the indoor air quality.

제안 방법

Also it was reported that natural sericite emits far-infrared radiation that helps to activate the body[19]. The main objective of the present investigation was development of natural wall paint from easily available natural sericite clay mineral to reduce the harmful effects of various commercial paints. Furthermore, the total amount of VOC, toluene and formaldehyde released from the NWP and toxicity index were also assessed to obtain indoor air quality standard.

대상 데이터

Sericite clay used in this study was obtained from Dongyang Mine, Samchuck, South Korea. Thickener (TYLOSE HS30000YP2, ISO Korea), dispersing agent (Sokalan PA 30, ISO Korea), antifoaming agent (NDW, ISO, Korea), resin (YE-110, Yongjin industries, Korea) and other chemicals were industrial grade reagents and were used as received.

De-ionized water was used as the main diluent of the paint.

이론/모형

The measurement conditions are shown in Table 2. Volatile organic compounds (VOCs) in the test chamber were analyzed using KSM ISO 11890-2 : 2007 standards. Indoor air quality testing standards process (MOE Notice No.
