Definitions
- the present process is not satisfied with simply covering one side or the different sides of the product to be protected, but it penetrates into the interior of the cells, surrounding all the capillary shaped bodies, modifying their internal texture,
- the present invention has therefore for its object a process for imparting to any paper, pasteboard or fabric, as also to all fibrous or woody material, treated according to the method disclosed below, qualities of impermeability to water, alcohols, hydrocarbons, humidity, acids. fatty bodies, butters, dairy products, greases, soft soaps, fertilizers, superphosphates, efllorescent, hydroscopic or humid products, fresh fish, meats etc., and even to certain aeriform bodies.
- the present process of impregnation and fireprooflng is applicable to all paper, pasteboard, fabric, fibrous or woody material, either at the outset or in the course of its manufacture or at the completion of this manufacture, whether the material obtained is glued or not glued, whether it is in sheets, in reels or transformed into manufactured objects such as boxes, containers, bottles, pots, tubes, various receptacles of any shape whatever, carpets, cords, strings, tapestry, sacks etc.
- the present invention adds to all the qualities disclosed above, both from the point of view of resistance to water, greases, and to salts, as well i as of resistance to the transmission of fire or flames, the following qualifications:which are only given by way of example and are not restrictive: a
- the paper is caused to pass from the roller or reel from which it unwinds, into the first bath.
- This first bath consists of an aqueous solution obtained from a combination formed by a metallic' carbonate such as sodium carbonate with a fatty acid such as stearate acid, which is saponifled by said metallic carbonate.
- a metallic' carbonate such as sodium carbonate
- a fatty acid such as stearate acid
- the fibres are thus impregnated with an emul sion of alkaline salts of fatty acids.
- the paper then passes into the second bath constituted by an aqueous solution of zinc sulphate of a more or less high percentage according to the qualities aimed at.
- the fibres are thus impregnated with the resulting stearate of zinc, insoluble in water, alerhol or ether, which is formed by the double decomposition between the sulphate of zinc and the sodium stearate, both in aqueous solution; the fibres are thus made non-wettable in the ordinary sense.
- the paper, pasteboard or fabric then passes into the third bath constituted by an aqueous fireproof and non-oxidizing solution of 10% of salts comprising: 1% of hydrated sodium borate, 5% of sodium phosphate, 2%, of ammonium phosphate, 1.5% sodium tungstate, and 0.5% 'of phosphorus oxychloride.
- the sodium tungstate is utilized to compensatefor the ammoniacal losses which the heat of the calenders might occasion, although these latter are kept at very low temperatures, varying between 30 and 75 centigrade, with a mean of 50 centigrade;- furthermore, care is taken to add to this solution of borated phosphatotungstate, a small quantity of gelatine which will serve as a support to the internal impregnation of the fibres and to the protective coating whiclrwill prevent the action of the oxygen of the air on flame, fire or combustion, with which protective coating the fibres will be covered on leaving the third bath.
- the bath or baths which follow will be simple washings, at ordinary temperature in water to which is added a small quantity of phosphorus oxychloride or chlorine or calcic salts, and the material again compressed will be dried, calendered and glazed and it may thenbe given all the usual decorations, g'raining, or the like; it is then placed on reels, in sheets or inpieces and supplied to the trade.
- vats filled with solutions kept at the most suitable temperature may be replaced by pistols or other apparatus spraying or atomizing the said solutions, the final washing taking place between sprayers.
- drying may also be facilitated by the use of vacuum or hot air,-in the same way, that each impregnating vat may be followed by heated calenders, dehydrating more or less on its passage the material under treatment, which will improve its absorbent qualities when passing into the following bath.
- concentrations of the solutions above described may vary according to the nature of the cellulose constituting the papers or pasteboards, of the threads which constitute the fabrics, and of the vegetable fibres used in the manufacture of the cords, and in general of any texture, textile fabric or ligneous material treated or to be treated, and minimum time of steeping, of moistening in the baths or of spraying or atomizing by compressed air pistols.
- it is desired simply to treat cords, fibres or capitaous materials not wound on drums or reels it is sufficient to plunge them into the above-mentioned baths.
- the papers, pasteboards, fabrics or other ligneous materials may be subjected to much more ordinary treatments by replacing the metallic stearate mentioned by any other metallic stearate, and the colloidal product serving as a support for the fireproof material by any other product furnishing a ,gel adapted to be made insoluble in the course of the subsequent fireproofing operations.
- Pasteboards, papers or fabrics, once treated by the above-disclosed process, are entirely modified in their composition and have acquired as a consequence of the said treatment, remarkable qualities of impermeability which will permit their use in particular for packing and the despatch of merchandise, of humid products, fatty matters, soft soaps, roasted coffee, fertilizers, salts, chemical products, fresh fish, materials likely to soil, diary products etc.
- the present invention consequently permits of obtaining a more complete and durable impermeability of papers, pasteboards, fabrics or ligneous materials, in particular in the use of packages for dairy products, humid, acid, efliorescent, and hygroscopic products, etc. than with the processes at present known.
- the present invention permits of adding to this said novel process of waterproofing-fireproofing qualities obtained by novel processes which by their anti-oxygen form will insulate or oppose any development of fire, of flames, or of combustion.
- the present invention is very economical both from the point of view of the price of the initial materials used as from that of the cost of the plant permitting the said impregnation and fireproofing.
- the said invention by the mixture, reactions or combinations of the bodies employed for protection against humidity, acids, water, fatty bodies, etc. ensures to the materials thus treated, an impermeability superior to that known hitherto in the field of the protection of products having an absorbent character.
- the present invention by the mixture, reactions of combinations of the products employed for fireproofing the materials treated, ensures to them a protection superior to any hitherto known in the field of protection against fire.
- the present invention permits of transforming by its application, the bodies treated into new products, having novel qualities, novel uses and absolutely novel applications in all departments of industry.
- a process for treating fibrous materials to render them impervious to liquids and fireproof which comprises impregnating the material with zinc stearate by treating said fibrous materials successively with sodium stearate and zinc sulphate, then treating the material thus impregnated at 30-75" C., with a fireproofing solution prepared by mixing together a solution comprising an alkali tungstate, borate and phosphate with a solution obtained by mixing aqueous ammonia with phosphorous oxychloride, then treating said material with a solution of gelatine, and finally hardening the said gelatine by treatment with formalin.
