COMPOSITION AND PROCESS FOR TREATING OLD WOOD ARTIFACTS AGAINST INSECTS, FUNGI AND WATER

The invention relates to a method for treating old wood artifacts. According to the invention, the method consists in preparing a colloidal nanodispersion based on red oil, alcoholic solution of a mixture of propolis and tannin and alcoholic extract of teak wood, in a volumetric ratio of 90:6:4, and applying the same in a differentiated manner, on small artifacts, by immersion for 10...30 min or, on large-sized structures, by brushing, injecting or spraying, while repeating the operation 2...5 times, at intervals of 25 h, after which the degraded wood, so cleaned and stiffened by nanofilming, is subjected to microstructural stabilization by application of a mixture of wax, paraffin, fine dust of teak wood and pigment in a mass ratio of 5:3.5:1.4:0.1, after which the surfaces are scumbled or laquered for esthetic purposes and for weather and mechanical protection. Invenţia se referă la o metodă de tratare a artefactelor din lemn vechi. Metoda, conform invenţiei constă în prepararea unei nanodispersii coloidale pe bază de petrol roşu, soluţie alcoolică de amestec propolis şi tanin şi extract alcoolic din lemn de tec în raport volumetric 90:6:4 şi aplicarea diferenţiat, la artefacte mici, prin imersie timp de 10...30 min, sau la structuri mari, prin pensulare, injectare sau pulverizare, cu repetarea operaţiei, de 2...5 ori, la intervale de 25 h, după care lemnul degradat igienizat şi consolidat prin nanopeliculizare, este stabilizat microstructural prin aplicarea unui amestec de ceară, parafină, rumeguş fin de lemn de tec, pigment în raport masic de 5:3,5:1,4:0,1, urmat de vernisarea sau lăcuirea suprafeţelor, cu rol estetic şi de protecţie climatică şi mecanică. :
