Description

Lipophilic silicate with foul smell and volatile organic compounds removability and manufacturing method

The present invention relates to a lipophilic silicate having a odor and VOC's removal function and a method for producing the same, and more particularly, by treating the silicate with an organic agent to form a lipophilic silicate of reduced polarity, The present invention relates to a lipophilic silicate having a odor and a VOC's removal function that can be uniformly dispersed and easy to intercalate when mixed with an oily synthetic resin, and thus can utilize odor and VOC's removal function of the silicate.

In general, most synthetic resins are lipophilic and release harmful gases causing new car syndrome and the like. Accordingly, efforts have been made to constantly develop new synthetic resins and to impart a deodorizing function thereto. In addition, in the case of synthetic resins used as interior materials and exterior materials for automobiles, electronics, and electrical appliances, continuous efforts have been made to reduce fuel efficiency and improve productivity due to light weight.

Various techniques have been developed for the use of silicates as such odor removal and lightweight agents. The silicates form an ininitely long chain or two dimensional sheet structure, and in the case of aluminosilicate in which silicon is substituted with aluminum, the silicate has a three dimensional framework structure. Due to the oxygen sharing of silicon, which is the basic skeleton of these silicates, the silicate has a very polar hydrophilic property due to the charge balance cation introduced to cancel the intrinsic anion and the -OH group present at the terminal of the structure. As a result, silicates are difficult to disperse when mixed with synthetic resins, which are mostly lipophilic, and intercalation, which is a phenomenon in which ions are intercalated into the crystal space. It has caused a problem of disruption.

In addition, recently, as represented by sick house syndrome and new car syndrome, the problem of pollution of the living environment by harmful substances such as formaldehyde generated from housing construction materials and the like is rapidly increasing. In addition, not only formaldehyde but also hardly decomposable volatile organic compounds having aromatic rings such as xylene, methylmercaptan, hydrogen sulfide, phenol, trimethylamine, etc. are regulated by indoor air environment guidelines.

Here, volatile organic compounds, ie, VOC's (volatile organic compounds), refer to petrochemical products having a vapor pressure of more than 10.3 kilopascals (or 1.5 psia) among hydrocarbons. Substances announced in consultation with the Chairman (Article 39, Paragraph 1, Enforcement Decree of the Atmospheric Environment Conservation Act), and in the US EPA, 'VOC's are characterized by NOx and photochemical oxidation reactions by sunlight in the atmosphere. It is defined as an organic compound that causes smog by increasing ozone concentration.

Representative hazards of VOC's include that the substance itself is harmful to the human body and causes acute disorders such as anesthesia (inhibition of the central nervous system), dizziness, paralysis and death upon exposure to high concentrations of VOC's.

Since 1980, Korea has been trying to improve national welfare and increase income due to rapid industrial development, but pollutants such as odor and VOC's have been emitted from various raw materials and wastes, which are by-products of the industrial economy. In 1996, VOC's were discharged during the process of petroleum refining and petrochemical production at Yeocheon Petrochemical Complex, causing large complaints such as complaints of odor pollution by residents, and in 1997, a large part of the causes of odor complaints in Sihwa area were VOC's It is estimated to be due to emissions.

The treatment method of VOC's can be divided into the method of recovering / reusing VOC material and decomposing it. Where the VOC's emitted are relatively high concentrations from a single outlet and are economical, it is desirable to have a recovery facility. Activated carbon adsorption, washing and low temperature condensation are techniques used when recovery is possible. If the recovery value of the VOC's is sufficient, the installation and operation of the recovery facility is efficient, but if the VOC's are a mixture, not a single substance, or if it is a hazardous substance or there is no recovery value, it is better to install a decomposition facility rather than a recovery facility. Preferably, thermal incineration, catalytic incineration, biofiltration and the like are available techniques for the decomposition of VOC's.

In addition, looking at the domestic prior patents related to the deodorant, it discloses a malodor treatment agent (Korean Patent No. 332511) in which rice bran is blended with yeast, kneaded with zeolite, kneaded and fermented, and then mixed and dried with iron sulfate. Activated carbon and nonwoven fabrics and a method of manufacturing the same (Korean Patent No. 139559) are known. The carbon dioxide adsorbent using natural zeolite is characterized in that the mordenite-based natural zeolite is heat treated at 200 to 350 ° C., followed by acid treatment with an aqueous hydrochloric acid solution of 0.8 N or less, followed by calcium ion exchange with an aqueous calcium chloride solution of 0.7 N or less. A manufacturing method (Korean Patent Application No. 1988-017920) is described.

However, such a conventional odor and VOC's treatment method has a substantially low value of odor removal efficiency, high initial construction cost, secondary waste generation, and operating costs are also uneconomical, so its practical use value when applied to the site Very few In particular, in the case of a thermal incinerator, the operating cost is high due to the cost of auxiliary fuel, the gas flow rate is increased, the residence time is shortened, and incomplete combustion is not suitable when the combustion gas is not well mixed, so it is not suitable in the case of severe fluctuations in the flow rate. In addition, increasing the gas flow rate lowers the combustion chamber temperature and lowers the treatment efficiency, which is generally not effective for low concentration VOC's treatment.

The present invention is to solve the problems of the prior art to develop an organicized lipophilic silicate that is easy to disperse and intercalate when mixing the lipophilic synthetic resin and silicate, and to remove odor and VOC's by the silicate It is an object to provide a lipophilic silicate having.

The above object of the present invention can be achieved by forming an lipophilic silicate comprising an organic agent composed of an alkyl compound combined with a reduced silicate polarity.

In addition, the present invention provides a method for removing lipophilic silicate that has high odor removal efficiency, no construction cost and no running cost, no secondary waste, no flow fluctuation, and is effective for low concentration VOC's treatment. Its purpose is to.

The object of the present invention is to disperse the silicate in water; Mixing an alkyl compound acting as an organic agent to the dispersed silicate; Reacting the mixture at an atmospheric pressure of 20 to 100 ° C. to reduce the polarity of the silicate by intercalating ions of the alkyl compound into the crystal space of the silicate; And it can be achieved by providing a lipophilic silicate production method comprising the step of drying.

The present invention provides a lipophilic silicate comprising a silicate having reduced polarity by combining an organic agent composed of an alkyl compound in the lipophilic silicate having a malodor and VOC's removal function.

In particular, the present invention, when used as a functional additive in the final resin while excluding the use of environmentally harmful substances, minimizes the absorption of moisture to maintain a stable physical properties, and further improve the quality of the surface of the molding and at the same time odor and lightweight function The present invention relates to a lipophilic silicate which can be efficiently provided.

Zeolite is a silicate mineral of aluminum containing alkali metals such as sodium and potassium and alkaline earth metals such as calcium and containing crystal water. There are many kinds, but two types of clonotilolite and mordenite are widely distributed. There is. The study of zeolite synthesis, which was initiated by mineral scientists to interpret the conditions and environment of natural zeolites, was successfully conducted in the 1940s by a series of synthesis experiments focused on Union Carbide for industrial applications. It started in earnest from the beginning. The synthesis of zeolites is generally accomplished by hydrothermal synthesis in the temperature range below 200 ° C.

In the zeolite synthesis method of the present invention, aluminosilicate or the like was used as a raw material. In general, the synthesis process does not require special pressure conditions and proceeds at low temperatures.

Since zeolite's crystal water exists as a water molecule unlike ordinary structure water, it is called 'non-stone water' and the structure is not destroyed even if it is dehydrated by heating, and the water molecule remains as a sponge or void as it is. Adsorption of water or gas to its original form has the characteristics, and its use has been broadened by using adsorption, moisture absorption, and cation exchangeability.

Specifically, in the present invention, the silicate is treated with an organic compound having 10 to 70 carbon atoms to reduce polarity and exhibit lipophilic properties, and the lipophilic silicates added to the resin are stably dispersed by the lipophilic properties, resulting in malodor and formaldehyde. Volatile Organic Compounds (VOC's) represented by, methyl mercaptan, hydrogen sulfide, phenol, xylene, trimethylamine, etc. can be removed efficiently. And lipophilic silicates that can be used for interiors such as furniture and interiors of automobiles, vehicles, ships, aircrafts, and the like.

The lipophilic silicate is formed of 1 to 1000 parts by weight of the silicate and 0.1 to 20 parts by weight of the organic agent. Within this range, the water-penetrating inhibitory function of the lipophilic silicate is exerted, and when it is out of the above range, the lipophilic property is reduced.

The silicates include spheres, powders, discs, carriers, and indeterminates. The lipophilic silicates using spherical silicates can be used for homogeneous dispersion and thick paint, glass, or finishing materials, and the lipophilic silicates using powder type silicates can be used for homogeneous dispersion and thin coatings or finishing materials, etc. The lipophilic silicate using the type silicate can be used for putty or interior material having a very thick coating film, and the lipophilic silicate using the carrier type silicate can be used for the finishing material using a special resin containing metal, and the lipophilic silicate using the amorphous silicate. The oily silicate may be used for mortar or interior materials, but the use thereof is not limited.

In particular, the silicates include spherical aluminosilicates, powdered aluminosilicates, or soda-lime silicates.

The lipophilic silicate using the spherical aluminosilicate may be used for insulating paints, putty, glass or finish, etc., the lipophilic silicate using the powdered aluminosilicate may be used for the coating, wallpaper or finish used as a thin film, The lipophilic silicate using the soda-lime silicate may be used in plate glass or interior materials, but the use thereof is not limited.

In addition, the organic agent includes alkyl ammonium having 10 to 70 carbon atoms. In addition, the organic agent reduces the polarity of the silicate through the ion exchange reaction with the charge balancing cation of the silicate as a macromolecule.

Here, the organicizing agent is cetrimonium chloride (Cetrimonium Chloride), steartrimonium chloride (Steartrimonium Chloride), Benzethonium chloride (Benzethonium Chloride), Behentrimonium Chloride (Behentrimonium Chloride), Distearyldimonium Chloride ), Stearalkonium chloride), lauryldimethylbenzylammonium Chloride, or lecithin.

In this case, the organic agent is in the form of alkylammonium chloride, but is not limited thereto.

Depending on the use of the lipophilic silicate, the organic agent may be used alone or in combination.

The lipophilic silicate has odor and VOC's removal. Here, the odor and VOC's removal functions are inherent in the silicates, but the original properties are doubled by lipophilizing the silicates to stabilize and maintain the physical properties, resulting in odor removal and VOC's removal.

The lipophilic silicate is characterized in that the odor and VOC's deodorizing ability test according to the KS M0062: 2003 standard.

Here, the KS M0062: 2003 standard puts the lipophilic silicate synthesized in the inner white box, injects the deodorizing target gas to a certain concentration in the box, and the time passes at intervals of 0, 30, 60, 90, 120 minutes. As a result, a certain amount of gas is drawn out to measure the concentration of residual gas in the detection tube, and the relative deodorization force of the lipophilic silicate is calculated by comparing with Blank.

Examples of the deodorizing target gas include formaldehyde, phenol, methylmercaptan, hydrogen sulfide, trimethylamine, styrene and the like.

In addition, as mentioned above, the use of the lipophilic silicate includes paints, coatings, putty, mortar, wallpaper, glass, storage containers, adsorbents, insulations, finishes, or interior materials. However, the use is not limited as above.

The silicate is dispersed in water using a stirrer, and when the alkyl compound is mixed with the dispersed silicate, the silicate and the alkyl compound are subjected to a cation exchange reaction. Thereafter, the mixture is heated at atmospheric pressure to help the cations of the alkyl compound penetrate into the crystal space of the silicate and to bind stably. Finally, the intercalated silicate is dried to prepare the lipophilic silicate.

The prepared lipophilic silicate is formed into a long chain, two-dimensional sheet or three-dimensional network structure. The lipophilic silicate of the long chain, two-dimensional sheet or three-dimensional network structure is prepared according to the shape combined with the organic agent.

Reducing the polarity of the silicate includes a cation exchange reaction between the charge balancing cation of the silicate and the organic agent. By the cation exchange reaction, the organizing agent and the silicate are intercalated to reduce the polarity of the silicate. Although the OH-group at the end of the silicate is still polar, the polarity of the OH-group is largely resolved by the intercalation, thereby making the lipophilic silicate entirely.

Figure 1 is a photograph showing the lipophilic of the lipophilic silicate prepared by the above method. As shown in FIG. 1, the lipophilic silicate exhibits lipophilic properties separated from water without being mixed with water. In addition, the lipophilic silicate has a characteristic of forming an upper layer having an apparent specific gravity smaller than that of water.

As described above, the lipophilic silicate having a odor and VOC's removal function and a method for preparing the same according to the present invention are easy to remove odors and VOC's by lipophilic silicate combined with an organic agent without harmful substances. . In addition, even when mixed with the resin and used repeatedly, the physical properties of the final resin are not changed, and the advantage that the deterioration of the function is prevented is remarkable. In addition, it is very useful for storage of petroleum products and volatile liquid substances, adsorbents of anti-source adsorption facilities such as process emission materials of synthetic organic chemical manufacturing facilities and paint manufacturing facilities, paints, wallpaper, glass, finishing materials, or interior materials.
