BIODEGRADABLE SUBSTANCE BASED ON NATURAL POLYMERS Russian patent published in 2019 - IPC C08L3/02 C08K5/53 C08K5/09 C08L101/16 

FIELD: manufacturing technology.

SUBSTANCE: object of the invention is to reduce the period of biodegradation. Set task is solved due to that biodegradable substance based on natural polymers, containing plasticiser, biodegradable filler, cellulose filler, according to the invention additionally contains citric acid and water, glycerine is used as a plasticiser, starch from sub-standard wheat grains is used as biodegradable filler, cellulose filler used is beef pulp flour, with the following ratio of components, wt%: starch from sub-standard wheat grains – 17.1; beet pulp flour – 17.1; glycerine – 8.4; citric acid – 0.5; water – 56.9. Thus, using the disclosed biodegradable substance based on natural polymers enables to reduce the length of biodegradation to 45 days.

EFFECT: obtaining a biodegradable substance having a controlled service life, which enables to predict the field of use of the material.
