LIGNOCELLULOSE POLYMER COMPOSITE MATERIAL Russian patent published in 2016 - IPC C08L97/02 C08L23/06 C08L23/12 C08L25/06 C08L27/06 

FIELD: chemistry.

SUBSTANCE: invention relates to production of lignocellulose polymer composite materials and products based thereon and can be used for producing construction, structural and finishing materials, as well as for production of furniture, products of domestic and industrial purposes. Lignocellulose polymer composite material contains a polymer matrix and lignocellulose filler, polymer matrix used is polyethylene in amount of 80-20 wt%, the filler is represented by buckwheat husks in amount of 20-80 wt%. Besides, using natural dyes of polyphenolic nature, extracted from buckwheat husks with molten polymer, allows to produce finished product of different shades of brown colour.

EFFECT: technical result consists in improvement of ecological compatibility of the ready product due to increased share of used wastes of buckwheat processing and minimal usage of chemical additives in the manufacturing technique and production of materials and products with high level of technical characteristics.
