Research physic-mechanical properties of composite materials on the base of crushed wood

[摘要] Influence of traditional thermoset (urea - and phenol-formaldehyde) and thermoplastic alternative (recycled high density polyethylene and recycled polypropylene) binders on the performance of slab composite materials using as a filler of the special pieces of wood chips are considered. Results studies of physic-mechanical properties of considered materials are presented. Rational conditions production of plate materials based on recycled thermoplastic matrices are revealed. Comparative analysis of wood-polymer composite materials based on two types of adhesives have allowed to establish the possibility of obtaining competitive materials based on recycled thermoplastics with higher water resistance (in terms of swelling in thickness meet the requirements of GOST (Interstate standard) 32399-2013 for plates of type P7) and strength characteristics compared with materials based on traditional thermosetting adhesives. Using of thermoplastic binders indicates the feasibility of their use in production of particle boards due to the positive effect on the environment.
