Definitions
- This invention relates to a process for waterproofing fibrous materials, and more particularly to a method of imparting Water-repellent properties to fibrous materials with the aid of condensation products formed from metal alcoholates and acid high-molecular organic derivatives of phosphoric acid.
- the waterproofingagent used in accordance with the present invention primarily aluminum alcoholates, such as aluminum isop-ropylate, aluminum. butylate, aluminum octylate, aluminum -dodecylate, or alcoh'olates of other, preferably low-molecular, organic hydroxyl compounds, the alkyl radicals of which mayalso comprise substituents, such as halogen, may be used as starting materials.
- aluminum alcoholates such as aluminum isop-ropylate, aluminum. butylate, aluminum octylate, aluminum -dodecylate, or alcoh'olates of other, preferably low-molecular, organic hydroxyl compounds, the alkyl radicals of which mayalso comprise substituents, such as halogen, may be used as starting materials.
- Phosphoric acid esters of organic hydroxyl compounds suitable for the production of the condensation products used as waterproofing agents in accordance with the presentinvention are primarily the corresponding monoalkyl esters with-alkyl radicals having at least 6 carbon atoms in the alkyl chain, such as phosphoric acid monooctyl ester, phosphoric acid monododecyl ester, phosphoric acid monooleyl ester, as well as phosphoric acid monoalkylphenol esters wherein the alkyl radicals have from 3 to 18 carbon atoms, phosphoric acid mononaphthenyl ester, phosphoric acid monoabietyl ester, and the like.
- the corresponding di-esters, inadmixture with mono esters may be used, as well as. those'esters the alcohol radicals of which carry substituentsor' are'interrupted by oxygen, sulfur or nitrogen atoms or by groups containing oxygen, sulfur and/or nitrogen.
- the acid phosphoric acid esters also other high;- molecular organic derivatives of phosphoric acids maybe used, such as the corresponding acid phosphoric acid alkyl amides, alkyl phosphonic acids, alkyl phosphinic acids, and the like. 1
- condensation products are formed in the presence of inert organic solvents, such as isopropanol, trichloroethylene or toluene, as well as other low-molecular alcohols, aliphatic halogenated hydrocarbons or aromatic hydrocarbons.
- inert organic solvents such as isopropanol, trichloroethylene or toluene
- other low-molecular alcohols such as aliphatic halogenated hydrocarbons or aromatic hydrocarbons.
- condensation products which contain, for example, polyvalent metal monohydroxy alcoholates and phosphoric acid monoalkyl in diiferent molecular proportions;- is accomplished by combining solutions of the starting components in the above solvents and thereafter heating the resulting mixture for a short time, if'necessary, to temperatures between 30 and 50 C.
- the starting components are used in a molar ratio of alcoholate to phosphoric acid ester from 1E0.5 to 1:1.5, but other molar ratios may also be used.
- solutions of the starting materials in the solvents may also be used for direct application to the fibrous material.
- the solvents may also be distilled off and the residue may be dissolved in other suitable media which are customarily used toproduce impregnations on fibrous'materials, such as vegetable, animal or mineral oils, fats or waxes.
- hydrocarboxylic 'acid esters 'compounds with reactive methylene groups, hydroxy-oxo compounds which are capable of being arranged into anacidic form, such as acetylacetone and acetoacetic acid ester, as well as oximes and ⁇ so forth.
- the present invention is particularly well adapted for the production of water-repellent impregnations on textile materials in the form of fibers, flakes, threads, ribbons, woven fabrics, knitted fabrics made of natural or synthetic fiber materials, especially rayon, spun rayon,
- fibers such as polyamide and polyester fibers, V polyacrylicester and polyacrylic-nitrile fibers, polyvinylchloride fibers, alignate fibers,'glass fibers, and the like.
- fibrous-materials such as, paper,*cardboard, cellulose, wood pulp, wood, and the like, may be rendered water-repellent with the aid of the waterproofing agents described herein.
- Non-fibrous materials may also be rendered water-repellent therewith.
- Non-fibrous materials to which the waterproofing agents may advantageously be applied include the surfaces of plastics, painted surfaces, metal surfaces, and so forth.
- ceramic materials and other porous building materials may also be rendered waterproof by impregnation with the condensation products or solutions described above.
- the process according to the present invention may advantageously be practiced by immersing the materials to be waterproofed in solutions which contain about 0.5 to 5.0%, preferably from 2 to 3%, by weight of-the above-described condensation product or mixtures thereof, or by brushing, and especially by spraying, such materials with these solutions.
- solutions which contain about 0.5 to 5.0%, preferably from 2 to 3%, by weight of-the above-described condensation product or mixtures thereof, or by brushing, and especially by spraying, such materials with these solutions.
- various hydrophobic effects may be obtained, such as water-repellent effects, water-resistance or water-impermeability.
- the fibrous materials are preferably subjected to the impregnation in the dry state. After the impregnation with the waterproofing agents, the fibrous material is advantageously heated for a short period of time, if necessary in the presence of moisture, for example with the aid of steam, whereby the waterproofing effects are still further improved.
- the waterproofing agents used in the examples below were produced by first dissolving the metal alcoholates in an organic solvent, such as in trichloroethylene or benzene, and thereafter stirring a solution of the high molecular acid phosphoric acid alkyl ester in an identical or similar solvent into the metal alcoholate solution. After the two solutions were combined, the solution mixture was heated for a short period of time, for example from 3 to 6 minutes. The solution mixture was then ready for use in the impregnation step. It may, however, also be admixed with small amounts of a stabilizing agent. The solution mixture was used in the resulting concentration or in a more diluted state, which was achieved by merely adding more of the respective solvent.
- an organic solvent such as in trichloroethylene or benzene
