| Title of the article | Creation of foamed wood-polymer composites based on polyvinylchloride |
| Abstract. | In this work the possibility of receiving the foam wood-polymer composites on the basis of polyvinyl chloride (PVC) was investigated, wich have higher physical and mechanical properties, flame retardant compared with other thermoplastic polymers (PE, PP, PS). Nevertheless, they have disadvantages, one of which is a material of high density (1300-1400 kg/m3) when compared with the products from natural wood (500-600 kg/m3) and wood-polymer composites based polyolefins, PS (900-1000 kg/m3). Influence of various chemical blowing agents (azodicarbonamide, sodium bicarbonate) and nucleator on physical and mechanical properties of the received materials was studied. Azodicarbonamide in comparison with bicarbonate of sodium is more effective as a blowing agent since it leads to formation of uniform close-meshed structure. It is established that introduction of a small amount of a wood-filler in melt of polymer interferes with decrease of density of samples even in the presence of gassing nucleators, which presumably occurs due to decrease in a pliability of melt to the excreted blowing gases. Authors reached decrease in density of composites by 10-15 % depending on extent of filling, without considerable deterioration of strength properties. |
