FIELD: chemistry.
SUBSTANCE: invention relates to production of a fire-resistant wood-polymer composite and can be used as a material which does not require additional processing and has a longer service life than wood. Disclosed is a wood-polymer composite composition containing: atactic polypropylene – 40.0 wt.%; wood flour treated with MWR – 50.0 wt.%; ammonium phosphate – 5.5 wt.%; aluminium trihydroxide – 4.0 wt.%; antioxidant AO-168 – 0.5 wt.%. Wood flour is pretreated with small doses of microwave radiation (MWR) for 5-10 seconds.
EFFECT: disclosed invention enables to obtain a wood-polymer composite with low flammability and improved strength and processing properties.
