Abstract: Optimization of the fractional composition of a composite building material based on high-pressure polyethylene grade 15803-020 and fine-dispersed wood processing waste with a fraction of 0,33…5,00 mm has been carried out. The optimal fractional composition of a composite building material made of recycled high-pressure polyethylene and fine wood processing waste has been determined. The distribution of wood filler by weight and size showed that the largest fraction has a fraction of 0,63…1,25 mm – 49,9 %. The optimal fractional composition of particles of secondary high-pressure polyethylene is provided with a fraction of less than 0,63 mm. Optimal concentrations of components in the product have been experimentally established, which varies in the following range: wood filler 69…71 % by weight, secondary high-pressure polyethylene 26…28 % by weight, modifying additives 3 % by weight (wax – 2,5 % by weight, LLDPE Coupling agent 04688 super concentrate – 0,3 % by weight, flame retardants – 0,2 % by weight).

Keywords: secondary high-pressure polyethylene, fine wood filler, fractional composition, composite polymer material.
