About the possibility of using 1-vinylnaphthalene to modify natural wood

Abstract

The work studies the possibility of using 1-vinylnaphthalene for modification and protective treatment of birch wood. 1-vinylnaphthalene used in the work was obtained by the method given in the literature. In order to facilitate the introduction of 1-vinylnaphthalene into the wood cavity, hydrocarbon impregnating solutions were prepared on its basis using toluene as a solvent. The samples of birch wood were kept in solutions for 24 hours at a temperature of 20°C after removing the wood samples from the impregnation baths, toluene was removed using a vacuum. After extracting the bulk of the toluene, the samples were subjected to heat treatment. It is shown that during heat treatment in conducting elements of birch wood under the influence of high temperatures, polymerization of 1-vinylnaphthalene proceeds by a radical mechanism. To determine the effect of 1-vinylnaphthalene content in wood on the properties of the resulting composites, toluene solutions with different modifier content were prepared. It is shown that with an increase in the content of the proposed modifier in birch wood, water absorption and swelling of samples of the resulting wood-polymer composites significantly decreases, which will increase the service life of products based on modified wood.
