Description
Procédé de préparation d'un mastic, et mastic obtenu suivant ce procédé. La présente invention est relative à. un procédé de préparation d'un mastic, dans le quel on utilise deux produits que l'on mélange iinmécliatement avant l'emploi et dont le pre- fuier constitue l'adhésif. et contient au moins un carbonate et une huile siccative, tandis que le second est une pâte siccative.
Il est connu d'utiliser, pour la. formation < ï' un mastic, un mélange de deux compositions dont, l'une constitue l'adhésif, tandis que l'autre est une pâte siccative. Toutefois, les niélanres de ce genre utilisés jusqu'à présent ne conviennent pas, d'une façon satisfaisante, pour adhérer à des parois métalliques.
La présente invention a notamment pour but. de remédier à cet inconvénient.
A cet effet, selon le procédé suivant l'in vention, on obtient la pâte siccative précitée en mélangeant un oxyde d'iui métal polyva lent., des silicates d'aluminium, de l'eau et un catalyseur pour le durcissement formé au moins en partie d'un oxyde de fer.
Selon une forme de réalisation avanta- oeuse du procédé suivant l'invention, on mé- lanc;@e à l'adhésif un oxyde de fer.
La présente invention a également pour objet le mastic obtenu par le procédé selon L'invention.
L'adhésif peut être constitué d'un mélange le craie ou d'autres carbonates, tels que ceux e magnésium, de strontium, de barium, dans des proportions en poids de 79 à. 89 %, d'hui- les siccatives, dans des proportions de 10 à 20 %, et d'oxydes de fer, dans des proportions de 0,5 à 3 0/0.
La pâte siccative peut contenir, mélangés, 60 à 70 % d'oxyde d'un métal polyvalent (bi, tri<B>...</B> ) autre que le fer et le chrome, 10 à 15 % de silicates d'aluminium, 7 à 13 % d'eau,
<B>5</B> à 10 % d'oxydes de fer et 7 à 15 % de com- posés de chrome (oxydes ou sels), les oxydes de fer et les sels de chrome constituant le catalyseur de durcissement qui, en outre, peut éventuellement comprendre une charge.
La prise s'effectue par le durcissement accéléré des huiles siccatives sous l'action des oxydes de métaux polyvalents et de l'oxygène de l'air. De plus, la présence de silicates et d'oxyde de fer provoque une grande adhé rence du mastic aux charpentes métalliques.
Il n'est pas strictement indispensable que l'adhésif contienne de l'oxyde de fer, la pro portion d'oxyde de fer dans la pâte siccative pouvant être choisie pour tenir compte de l'absence éventuelle d'oxyde de fer dans l'ad hésif; toutefois, la présence d'oxyde de fer dans l'adhésif donne à celui-ci un éclat parti culier qui permet de l'identifier facilement.
Immédiatement avant l'emploi du mastic, les deux produits sont mélangés, par exemple, clans des proportions de 10 parties de l'adhé sif pour une partie de la pâte siccative. Par sa composition, le mastic. obtenu peut être appli qué d'une Tacon très aisée sur les endroits requis.

Process for preparing a mastic, and mastic obtained by this process. The present invention relates to. a process for preparing a mastic, in which two products are used which are immediately mixed before use and the first of which constitutes the adhesive. and contains at least one carbonate and one drying oil, while the second is a drying paste.
It is known to use, for the. forming a mastic, a mixture of two compositions, one of which constitutes the adhesive, while the other is a drying paste. However, nielans of this kind used heretofore are not satisfactorily suitable for adhering to metal walls.
A particular aim of the present invention is. to remedy this drawback.
For this purpose, according to the process according to the invention, the aforementioned drying paste is obtained by mixing an oxide of slow polyvah metal, aluminum silicates, water and a catalyst for the curing formed at least partly of an iron oxide.
According to an advantageous embodiment of the process according to the invention, an iron oxide is mixed with the adhesive.
A subject of the present invention is also the mastic obtained by the process according to the invention.
The adhesive may consist of a mixture of chalk or other carbonates, such as those of magnesium, strontium, barium, in proportions by weight of 79 to. 89%, drying oils, in proportions of 10 to 20%, and iron oxides, in proportions of 0.5 to 30%.
The drying paste may contain, mixed, 60 to 70% oxide of a polyvalent metal (bi, tri <B> ... </B>) other than iron and chromium, 10 to 15% of silicates of 'aluminum, 7 to 13% water,
<B> 5 </B> 10% iron oxides and 7 to 15% chromium compounds (oxides or salts), iron oxides and chromium salts constituting the curing catalyst which, in additionally, may optionally include a charge.
The setting is effected by the accelerated hardening of the drying oils under the action of polyvalent metal oxides and oxygen in the air. In addition, the presence of silicates and iron oxide causes great adhesion of the mastic to metal structures.
It is not strictly necessary for the adhesive to contain iron oxide, the proportion of iron oxide in the drying paste being able to be chosen to take account of the possible absence of iron oxide in the drying paste. hesive ad; however, the presence of iron oxide in the adhesive gives it a special shine which allows it to be easily identified.
Immediately before using the mastic, the two products are mixed, for example, in proportions of 10 parts of the adhesive to one part of the drying paste. By its composition, mastic. obtained can be applied with a very easy tack on the required places.
