Abstract
Description
The present invention relates to a biodegradable partially thermoplastic composite material of casein and / or milk proteins in combination with sheep wool or animal hair in thicknesses of 0.5 mm to 100 mm.More particularly, the invention relates to a biodegradable combi material of casein, its proteins, a carbonate, an additive and mainly of sheep wool or other animal hair. The material comprises:between 5% and 80% by volume of casein and / or caseinate, preferably 55-70%between 12% and 50% water, preferably 15-45%between 10% and 85% sheep wool and / or other animal hairHardening agents and accelerators from the mineral class of water-containing carbonates, preferably 10-30%hydrophobic bioadditives, preferably 0.1-4%, for altering the surface structureThe combination of these components enables a water-repellent biodegradable material having thermoplastic properties and high environmental compatibility.
Claims
Biodegradable partially thermoplastic composite material consisting of: - 5-80 vol.% casein and / or caseinate, - 12-50 vol.% water, - 10-85 vol.% sheep wool and / or other animal hair, - 10-30 vol.% water containing carbonates as solidifier, - 0.1-4 vol.% hydrophobic bio-additive for surface modification.The material of claim 1, wherein the casein is between 55% and 70% by volume.The material according to claim 1 or 2, wherein the additive is based on natural, biodegradable granules.
