Title (EN) CELLUOSIC PRODUCTS COMPRISING SUBSTANTIALLY VOC-FREE COMPOSITIONS
(FR) PRODUITS CELLULOSIQUES COMPRENANT DES COMPOSITIONS SENSIBLEMENT EXEMPTES DE COV
Abstract:
(EN) Embodiments of a composition useful for forming cellulosic products are disclosed, as well as products made using disclosed compositions. One disclosed composition comprises effective amount of dihydroxyethylene urea(s), dihydroxypropanol ureas, glycoluril(s), or combinations thereof. Such compositions can be cross linked, or not. The compositions can include other materials, such as methylol melamine; maltodextrin, where the DE of the maltodextrin can vary from about 4 to about 25, optional auxiliary additives, including a surfactant; a trialkanolamine, a preservative, a fire retardant; an aesthetic material, such as a dye that, in certain embodiments, substantially completely penetrates the cross section of the board product; a hardness enhancer; and any and all combinations of such materials. One embodiment of a disclosed method for making a cellulosic product comprises first providing a disclosed composition and applying it to cellulosic material, such as by substantially immersing cellulosic material in desired compositions in an autoclave.
(FR) L'invention concerne des modes de réalisation d'une composition utile pour former des produits cellulosiques ainsi que des produits fabriqués au moyen de ces compositions. Une composition de l'invention comprend une quantité efficace de dihydroxyéthylène-urée(s), de dihydroxypropanol-urées, de glycoluril(s) ou de combinaisons de ces substances. Ces compositions peuvent être réticulées ou non réticulées. Elles peuvent comprendre d'autres substances, telles que de la méthylol-mélamine et de la maltodextrine, l'équivalent dextrose de la maltodextrine pouvant varier entre environ 4 et environ 25, des additifs auxiliaires optionnels, y compris un tensioactif, une trialcanolamine, un conservateur, un ignifuge, une substance esthétique, telle qu'un colorant qui, dans certains modes de réalisation, pénètre de manière sensiblement complète dans la section transversale du produit en carton, un renforçateur de dureté, et toute combinaison de ces substances. Un mode de réalisation d'un procédé de l'invention de fabrication d'un produit cellulosique consiste d'abord à obtenir une composition puis à l'appliquer sur une matière cellulosique, notamment en immergeant sensiblement la matière cellulosique dans les compositions souhaitées dans un autoclave.
