Abstract

Procedimiento para la fabricación de un adhesivo bajo forma de condensación de la urea y el formaldehído en los que se añaden a la solución utilizada para la impregnación del soporte o para la preparación del adhesivo en polvo el producto primario de condensación ya condensado previamente y neutralizado según un proceso apropiado y conocido catalizadores ácidos o que engendran ácidos por disociación tales como productos orgánicos ligeramente ácidos o cuyas sales o las sales de reacción ácida de ácidos minerales o de éteres orgánicos o de ácidos minerales mezclados con bases que actúan de productos de protección o de inactivación caracterizado porque se utiliza como mínimo dos materias para constituir el producto de protección y de inactivación de los cuales uno pasa en la reacción de condensación mientras el otro actúa simplemente de aglutinante y de producto-tampón y eso en proporciones cuantitativas tales que la solución de condensación produce una reacción neutra ligeramente alcalina o ligeramente ácida cuyo pH está situada entre 6 y 8.Process for the manufacture of an adhesive in the form of condensation of urea and formaldehyde in which the primary condensation product already previously condensed and neutralized according to the solution used for impregnation of the support or for the preparation of the powder adhesive is added. a suitable and known process acidic or acid-generating catalysts by dissociation such as slightly acidic organic products or whose salts or the acid reaction salts of mineral acids or of organic ethers or of mineral acids mixed with bases that act as protective or protective products inactivation characterized in that at least two materials are used to constitute the protection and inactivation product of which one passes in the condensation reaction while the other simply acts as a binder and a product-buffer and that in quantitative proportions such that the solution of condensation produces a slightly alkaline neutral reaction a or slightly acid whose pH is between 6 and 8.
