Title (EN) COMPOSITION AND METHOD OF MANUFACTURING THE SAME
(FR) COMPOSITION ET SON PROCÉDÉ DE FABRICATION
Abstract:
(EN) Fire retardant composition for treatment of various wood products, method of producing the same and uses therof. The comprositions comprise an aqueous solution of bisphosphonate selected from 1 -hydroxy ethane 1,1-diphosphonic acid, an alkanol amine, and optionally an alkaline agent, the composition having a pH in the range of 4.0 to 7.0. The composition can be produced by mixing together 30 to 50 parts by weight of 1 -hydroxyethane 1, 1 -diphosphonic acid; 1 to 10 parts by weight of an alkanol amine or mixture thereof, said alkanol amine being added in free form; and optionally 0.1 to 40 part by weight of an alkaline agent; and water. The compositions can be used for protecting wood not only against fire but also against mould, rot, blue stain, insect such as termite attacks on wood, dimensional changes, or a combination thereof due to environmental influence.
(FR) L'invention concerne une composition ignifuge pour le traitement de divers produits de bois, son procédé de production et ses utilisations. Les compositions comprennent une solution aqueuse de bisphosphonate choisie parmi l'acide 1-hydroxyéthane 1,1-diphosphonique, une alcanolamine et éventuellement un agent alcalin, la composition présentant un pH dans la plage de 4,0 à 7,0. La composition peut être produite par mélange de 30 à 50 parties en poids d'acide 1-hydroxyéthane 1,1-diphosphonique ; de 1 à 10 parties en poids d'une alcanolamine ou d'un mélange de ces derniers, ladite alcanolamine étant ajoutée sous forme libre ; et éventuellement de 0,1 à 40 parties en poids d'un agent alcalin ; et d'eau. Les compositions peuvent être utilisées pour protéger le bois non seulement contre le feu mais également contre la moisissure, la pourriture, le bleuissement, les insectes tels que les attaques par termites sur le bois, les changements dimensionnels, ou une combinaison de ces derniers en raison de l'influence de l'environnement.
