Abstract

The paper investigates the possibility of using petroleum polymer resins for modifying fiberboard. The main components in these resins are aromatic compounds. The object of the study was the fiberboard of the wet production method with a thickness of 3.2 mm. The petroleum polymer resin “Piroplast- 2K” was used to modify fiberboard. 5% NF-1 siccative was injected into the hydrocarbon solution of petroleum polymer resin used for impregnation. The impregnation of wood-fiber slabs was carried out by immersing the slabs in a resin solution and keeping it in it for 1 min. A comparative analysis ofthe properties was carried out with samples of plates treated with tallow oil. An analysis of the molecular weight parameters of the proposed impregnating composition showed the possibility of its easy penetration into the slab material. The introduction of petroleum polymer resin into the structure of fiberboard provides an increase (by 24.5–49.7%) in the strength parameters of the resulting material, increased water and moisture resistance (up to 1.56 times). In addition, the formation of substandard material is reduced by filling defects with resin. It has been shown that with the additional introduction of 30% of methyl methacrylate units into the composition of oligomeric molecules of petroleum polymer resins, modified boards are obtained that have higher strength properties, water and moisture resistance. Taking into account the fact that petroleum polymer resin is made from by-products of petrochemistry, its use for the modification of fiberboard will allow recycling waste from the petrochemical industry in a new direction, expand the use of by-products, use valuable hydrocarbon raw materials more efficiently and solve a number of environmental issues.
