Abstract:
PURPOSE: A producing method of low molecular weight lignin using a wood composite raw material is provided to prevent the environmental contamination, and to produce a coating film having antibacterial property. CONSTITUTION: A producing method of low molecular weight lignin using a wood composite raw material comprises the following steps: refining high molecule weight lignin from the wood composite raw material; decomposing the high molecule weight lignin to obtain the low molecular weight lignin; and extracting the obtained low molecular weight lignin. The average molecular weight of the high molecule weight lignin is greater than 5,000. The average molecular weight of the low molecule weight lignin is 100-500.
Abstract:
The present invention relates to a non-extended polyester-based film having an improved heat resistance and flexibility, a method to prepare the same, and an interior material film for wallpaper or a bottom material comprising the same. The method to prepare the non-extended polyester-based film comprises the step of: synthesizing poly-L-lactic acid bound to glycidyl methacrylate (GMA); and preparing a film containing polyester-based resin obtained by mixing poly-L-lactic acid bound to glycidyl methacrylate (GMA) with poly-D-lactic acid.
