Abstract
As the enhancement of indoor air quality is increasingly compelling the use of natural materials without any emission, this study reports the preparation and performance of natural garlic adhesives for wallpaper. The natural garlic adhesives were successfully prepared by the extraction of the clove of raw garlic with water to isolate carbohydrates and proteins. Properties of the prepared garlic adhesives such as the non volatile solids content, viscosity, density, and pH were 62%, 2,789 mPa.s, $1.3g/cm^3$, and 6.6, respectively. The non-volatile solids content has a great impact on the adhesion performance of the prepared garlic adhesives, which was adequate about 60%. Bonding strength of prepared garlic adhesives was greater than the requirement of a Korean standard for wallpaper. In addition, the garlic adhesives showed antibacterial activity inheriting from the garlic. It is expected that the prepared garlic adhesives could be used as safe and natural adhesives without emitting any volatile organic compounds and formaldehyde gas.
