Biomaterial product based on sunflower seed shells and/or sunflower seed hulls

摘要

The invention relates to a biomaterial product based on sunflower seed shells or sunflower seed hulls. The invention proposes the use, rather than of wood, bamboo, or other woodlike fiber products, of sunflower seed shells or sunflower seed hulls as starting material for the biomaterial products and the use thereof for producing such products, in order thereby to improve the existing biomaterials, including, in particular, by making them more cost-effective and enhancing their physical properties.

主权项

1. A method for producing a biomaterial product based on
sunflower seed shells or sunflower seed hulls, comprising the following steps:
providing or producing a compounded material,
the material resulting from compounding of a sunflower seed shell material or sunflower seed hull material with a plastics material,andprocessing the compounded material, or a compounded material resulting therefrom by treatment, at a temperature of 260° C. or less to form a biomaterial product,the total fraction of sunflower seed shell material or sunflower seed hull material in the biomaterial product being in the range from 20 to 60 wt %, based on the total mass of the biomaterial product, andthe biomaterial product preferably possessing
a density of 1 g/cm3 or greater than 1 g/cm3, and/oran elasticity modulus of 1000 MPa or greater than 1000 MPa, and/ora tensile strength of 10 MPa or greater than 10 MPa, and/oran elongation at break of 3% or greater than 3%.
