In one embodiment of the present invention, the composition further comprises an alkali metal salt, wherein the alkali metal is sodium or potassium.
In one embodiment of the present invention, the composition further comprises a toning agent or an antimicrobial agent.
In one embodiment of the present invention, the composition is formed into an aqueous solution, and then attached to the surface of the fiber material, followed by drying to obtain the fiber material with deodorizing and flame retarding functions.
In the aqueous solution formed by the composition, the content of the composition is 0.3-30 wt% for affinity reaction, preferably the content is 0.5-20%, and more preferably the content is 0.7-20%. The content of the composition is too small, and the deodorizing property of the deodorant is not easy to fully exert; if the content is too large, precipitates are generated after the solubility of water is exceeded, and the stability of the product is not facilitated.
The pH of the aqueous solution formed by the composition is neutral, most of the pH values of the malodorous substances are alkaline, and the pH value of the aqueous solution formed by the composition is suggested to be close to neutral, so that the composition can effectively react with the malodorous substances and remove the malodorous substances. The final adjustment of the pH in the aqueous solution formed by the composition can be carried out by using potassium hydroxide, calcium hydroxide, organic acid and the like, wherein the effect of using potassium hydroxide is better.
The aqueous solution of the composition may be added with a toner such as titanium oxide or an antibacterial agent, if necessary.
The composition forms an aqueous solution which can be diluted directly with water, used as a deodorizing spray or used directly as an air freshener. The composition forms an aqueous solution which absorbs malodorous substances in the malodorous gas, thereby extracting the malodorous substances from the gas.
The aqueous solution formed by the composition is used for wallpaper, non-woven fabrics, woven fabrics or fibers, and is dried, so that the composition has a deodorizing effect on ammonia gas and acetaldehyde gas, and has an effect of reducing the flammability degree of flammable paper or fiber products. The amount of each use is about 5-10 g/m2Is most preferred. These finished products can be used as interior materials for building materials, furniture, household goods, automobiles, airplanes, and the like.
The metal constituting the deodorizing metal salt may be mainly a transition metal such as vanadium, manganese, iron, cobalt, titanium, nickel, manganese, copper, zinc, silver, or the like, and the like, or lead, aluminum, magnesium, or the like. Among these metal salts, ferrous iron or zinc has excellent deodorizing properties for amine salts, hydrogen sulfide, ammonia, mercaptans and the like. The salt in which the metal is ferrous iron contains inorganic acid salt and organic acid salt. The inorganic acid salt is ferric sulfate, ferric chloride, ferric bromide, ferric iodide, etc. The organic acid salt is citric acid, malic acid, vitamin rubine, ferric lactate, ferric citrate, malic acid, anti-maleic acid, etc.
Magnesium salts of metals are also used as deodorizing metal salts. The magnesium salt is often used in combination with ferrous iron and zinc. The magnesium salt includes magnesium sulfate, magnesium chloride, magnesium carbonate, magnesium oxide carbonate hydrate, sodium magnesium sulfate, potassium magnesium sulfate, and potassium magnesium bicarbonate.
The alkali metal salt has a function of stabilizing the deodorizing metal and has flame retardancy. The alkali metal is exemplified by sodium and potassium. The deodorizing metal salt may form a complex with the basic metal salt. For example, an aqueous solution of a deodorant composition containing ferric sulfate and potassium sulfate is acid-adjusted to pH 4 to 10, and potassium aurocan, which is a divalent iron-detecting agent, is added, so that a substantially blue image is not developed.
The isoniazid compound and the adipic acid compound can be stably synthesized with ferrous iron, have good reaction on aldehydes and have flame retardance. The isoniazid compound and the adipic acid compound are contained in an amount of 0.1 to 8, preferably 0.5 to 5 equivalents per one equivalent of 1 of the deodorizing metal salt. Specifically, 100 units of ferrous sulfate contain 50 to 350 units of isoniazid compound and adipic acid compound, preferably 60 to 200 units of isoniazid compound and adipic acid compound. When the amounts of the isoniazid compound and the adipic acid compound are too large for the deodorizing metal salt, there is a risk of generation of ammonia gas or the like, and when the amounts of the isoniazid compound and the adipic acid compound are too small, the deodorizing effect is affected.
As the chelating agent, ethylenediaminetetramethylenephosphonic acid, aminotrimethylenephosphonic acid, citric acid, gluconic acid, iminodiacetic acid, diethyltriaminepentaacetic acid, nitrilotriacetic acid, diaminopropane tetraacetic acid, hydroxyethyliminodiacetic acid, disodium sebacate, hydroxyethylethylenediamine triacetic acid, or a water-soluble salt thereof; citric acid, gluconic acid, and other acids or water-soluble salts thereof. These chelating agents may be used alone or in a mixture. Among them, disodium sebacate and aminocarboxylic acids such as acetic acid and their water-soluble salts react well. For 1 equivalent of the deodorant metal salt, 0.001 to 0.08 equivalent of the chelating agent is used, preferably 0.005 to 0.04 equivalent of the chelating agent is used. Specifically, the amount of the disodium sebacate is 0.5 to 8 parts by weight, preferably 1 to 7 parts by weight, per 100 parts by weight of the iron sulfate (7 water salt).
Organic acids include fatty acids, aliphatic dicarboxylic acids, carbonyl carboxylic acids and other unsaturated fatty acids and hydroxy acids and (isoniazid compounds and adipic compounds) and the like.
Examples of the above-listed fatty acids are formic acid, acetic acid, capric acid, propionic acid, butyric acid, valeric acid, caproic acid, enanthic acid, caprylic acid, pelargonic acid, lauric acid, myristic acid, phosphoric acid, pentadecanoic acid, palmitic acid, stearic acid, oleic acid, linoleic acid, linolenic acid, dihydroabietic acid, unsaturated fatty acids, and the like. As dicarboxylic acids, oxalic acid and the like are exemplified. With aromatic compoundsExamples of acids include benzoic acid, phthalic acid, carbonic acid esters and other unsaturated fatty acids. In one embodiment of the present invention, 5 or more organic acids are selected and mixed. Among the above organic acids, a substance having no odor and high solubility in water is subjected to an affinity reaction. Citric acid, malic acid, or mixed acids may be used. The organic acid content of the deodorizing metal salt is 3X 10 to 1 equivalent~40.5, preferably 2X 10-30.01, further preferably 1X 10-30.01. Specifically, the citric acid is 0.5 to 8 parts by weight, preferably 0.1 to 5 parts by weight, based on 100 parts by weight of iron sulfate (7 parts by weight of water salt).
The composition containing an isoniazid compound and an adipic acid compound can exhibit reactivity with an aldehyde malodorous substance such as formaldehyde, and can stabilize a deodorant metal salt and make a deodorant more effective in removing the amine, hydrogen sulfide, ammonia, thiol, aldehyde malodorous substance. That is, the isoniazid compound and the adipic acid compound further improve the stability of the deodorizing metal salts such as ferrous sulfate and zinc sulfate in addition to the decomposition of the deodorizing aldehydes. The deodorizing metal salt and the isoniazid compound and the adipic acid compound may form a combination, that is, the alkali metal salt of the deodorizing metal ion and the isoniazid compound and the adipic acid compound form a ligand.
The isoniazid compound contains at least 1 amino group, for example, 2 or 3 or more amino groups in the molecule.
By adopting the fiber material with the functions of deodorization and flame retardance, the isoniazid compound and the adipic acid compound in the composition can stabilize the deodorizing metal salt, particularly ferrous salt or zinc salt, improve the decomposition and removal of amine, hydrogen sulfide, ammonia, mercaptan, aldehyde compounds and the like of the deodorant or freshener, and do not generate ammonia. Further, the composition may further comprise an alkali metal salt, i.e., the composition contains an alkali metal ion, and the alkali metal salt and the deodorant metal salt form a complex, thereby not only stabilizing the deodorant metal salt but also adjusting the pH of the deodorant composition. The composition used by the invention is also added with a stabilizer, a chelating agent and a pH regulator, wherein the stabilizer and the chelating agent further stabilize the deodorant metal salt and enhance the deodorization effect, and the pH regulator can enable the deodorant composition to effectively react with the malodorous substances to remove the malodorous substances and reduce the flammability degree of the malodorous substances. The product of the invention can be used as an interior material for building materials, furniture, household products, automobiles, airplanes and the like.
