BIO-BASED HEAT-CURABLE CASTING MIXTURE, MOULDED BODY PRODUCED THEREFROM, AND METHOD FOR PRODUCING SUCH MOULDED BODY Russian patent published in 2021 - IPC C08F2/44 C04B26/06 C04B26/18 C04B18/04 C08L33/08 C08L33/10 C08F265/06 B29C39/00 

FIELD: composite materials.

SUBSTANCE: invention relates to a bio-based heat-curable casting misture including: (a) one or several mono- and one or several polyfunctional acryl and/or methacryl biomonomers of plant or animal origin, (b) one or several polymers or copolymers selected from polyacrylates, polymethacrylates, polyols, polyesters from recycled material or of plant or animal origin, (c) inorganic filler particles of natural origin, wherein the proportion of mono- and polyfunctional or mono- and polyfunctional acryl and methacryl biomonomers is 10 to 40% wt., the proportion of polymer or polymers or copolymers is 1 to 16% wt., and the proportion of inorganic filler particles is 44 to 89% wt. The moulded body produced from the casting misture according to the invention consists almost entirely of biological, i.e. natural, materials.

EFFECT: production of biocomposite materials from filler particles and cross-linkable materials produced of renewable sources reduces the consumption of petrochemically manufactured materials, and thus, petroleum consumption, and has a positive impact on the environment.
