Lignin polymer, Composites for environmental-friendly interior materials of vehicle and Preparing method thereof

摘要

The present invention relates to a lignin polymer, a composite material for an environment-friendly automobile interior material using the same, and a method of manufacturing the same. More specifically, the present invention relates to a lignin polymer composition comprising lignin and sebacoyl chloride, (-COCl) are mixed so as to have a specific molar ratio, and to a process for producing the same. The present invention also relates to an environmentally friendly automobile interior material manufactured using the lignin polymer and a method for manufacturing the same. The present invention has the advantage of recycling resources because lignin, which is a waste, is recycled, and the automobile interior material produced using the lignin has little mechanical properties such as tensile strength and elongation as well as little volatile organic material. In addition, it is environmentally friendly because it is superior in degradability to existing automobile interior materials of petrochemical materials.;Lignin, sebacoyl chloride
