La présente invention apporte des perfectionnements aux compositions pour la préservation et l'ignifugation du bois et d'autres matières combustibles telles que des plaques en fibre de bois.
Il a déjà été proposé de former une composition com- prenant un bichromate, de sulfate de cuivre, du chlorure de zinc et de l'acide borique en solution aqueuse. Une composition de ce genre préserve bien le bois ainsi que d'autres matières de façon satisfaisante des maladies cryptogamiques.. des attaques d'insectes, des bestioles nuisibles et des organismes marins, @
<Desc/Clms Page number 2>
mais l'effet ignifuge de la composition n'est pas satisfaisant.
Une composition suivant l'invention se présente sous forme d'une poudre susceptible d'être dissoute dans l'eau avant. l'emploi et se compose d'un bichromate, d'acide borique,. de phosphate mono-ammonique, d'un sulfate ou d'un chlorure de cuivre,. de zinc ou de nickel,, et d'un agent de séquestration, capable, lorsque la composition est en solution aqueuse, d'empêcher un sel quelconque de se précipiter dans la solution.
L'agent de séquestration peut être un sel tel qu'un polyphosphate de sodium, par exemple de l'hexamétaphosphate de sodium.

La composition préférée est celle donnée dans l'exemple 1.
Les sels mentionnés plus haut sont dissous dans l'eau de façon à produire une solution contenant approximativement 16% en poids des sels.
On peut alors placer le bois ou une autre matière combustible à traiter dans un cylindre dont on aspire l'air de façon à créer un vide. Dans ces conditions, la solution est aspirée dans le cylindre jusque ce que ce dernier soit rempli.

The present invention provides improvements to compositions for the preservation and fireproofing of wood and other combustible materials such as wood fiber boards.
It has already been proposed to form a composition comprising a dichromate, copper sulfate, zinc chloride and boric acid in aqueous solution. A composition of this kind preserves wood and other materials well and satisfactorily against fungal diseases .. attacks by insects, pests and marine organisms, @
<Desc / Clms Page number 2>
but the flame retardant effect of the composition is not satisfactory.
A composition according to the invention is in the form of a powder capable of being dissolved in water beforehand. employment and consists of a dichromate, boric acid ,. mono-ammonium phosphate, a sulphate or a copper chloride ,. zinc or nickel, and a sequestering agent capable, when the composition is in aqueous solution, of preventing any salt from precipitating out of solution.
The sequestering agent can be a salt such as sodium polyphosphate, for example sodium hexametaphosphate.
Examples of compositions according to the invention are given below, all the proportions being expressed by weight: EXAMPLE 1 ,.

The preferred composition is that given in Example 1.
The above salts are dissolved in water to produce a solution containing approximately 16% by weight of the salts.
The wood or other combustible material to be treated can then be placed in a cylinder from which air is sucked in so as to create a vacuum. Under these conditions, the solution is sucked into the cylinder until the latter is filled.
Pressure is then applied to the contents of the cylinder so as to ensure a minimum retention of 21/2 pounds 1.1 kg) of composition
