Definitions
- the present invention relates to a vacuum insulator including a high specific surface area getter material, and more particularly to a getter material containing an active material for adsorption having a specific surface area of 5 ⁇ 40m 2 / g.
- the conventional vacuum insulator is manufactured by putting a glass fiber used as a core material into a multilayer film or a metal deposition film shell including aluminum foil, and mounting a getter and evacuating it.
- the double getter material serves to adsorb moisture, air or gas remaining inside or coming from the vacuum insulator.
- the residual moisture remaining in the core material, the outer shell material or the vacuum chamber is a heat transfer medium, which increases the thermal conductivity, causing thermal insulation performance to deteriorate.
- a getter material that absorbs moisture is mainly an active material for adsorption. Is being used.
- the active material for adsorption used as a getter material has a low specific surface area, which causes a slow reaction rate with water and a limited amount to adsorb water within the same time, thereby limiting initial thermal conductivity.
- Korean Patent Laid-Open Publication No. 10-2003-0072717 also describes a getter material which is an organic gas and a moisture adsorbent.
- the type of getter material is classified into a chemical getter material or a physical getter material, but the application is different, but the specific surface area is characterized. No getter material is disclosed. Therefore, the present invention is to develop a getter material to improve the initial thermal insulation performance by applying the active material for adsorption having a higher specific surface area to the vacuum insulation material to quickly absorb the residual moisture in the vacuum insulation material.
- An object of the present invention is to provide a getter material comprising a high specific surface area active material capable of improving the initial heat insulating performance of the vacuum insulation material.
- Still another object of the present invention is to provide a method for producing an active material for adsorption with improved specific surface area by acid treatment of calcium carbonate, which can be applied to a getter agent.
- a getter material comprising an active material for adsorption having a specific surface area of 5 ⁇ 40m 2 / g.
- the getter material including the high specific surface active material for adsorption is not limited in the amount that can adsorb moisture, it is possible to increase the initial thermal insulation performance of the vacuum insulation material comprising the getter material of the present invention.
- a getter material including a high specific surface active material for adsorption and a vacuum insulating material including the same can be obtained.
- the present invention provides a getter material comprising an active material for adsorption having a specific surface area of 5 to 40 m 2 / g.
- the getter material of the present invention contains an active material for adsorption.
- the active material for adsorption may be used as long as the active material for adsorption excellent in water adsorption performance, but is preferably an active material for adsorption having a specific surface area of 5 to 40 m 2 / g, and a specific surface area of 5 to 20 m 2 / It is more preferable that it is the active substance for adsorption which is g.
- the larger the specific surface area of the adsorption active material the better the ability to adsorb moisture, but it is preferable to satisfy the range of the specific surface area for proper mechanical properties and adsorptivity.
- the specific surface area is less than 5 m 2 / g, since the reactivity is very weak, it is difficult to quickly adsorb moisture inside the vacuum insulation material because the reaction does not occur well at room temperature when applied to the vacuum insulation material. In order to solve this problem, activation at a high temperature is required. However, when the temperature is increased, the polymer layer included in the outer cover material applied to the vacuum insulation material may be deteriorated. On the other hand, when the specific surface area exceeds 40 m 2 / g, there is a fear that the activity is deteriorated to a large extent prior to the application to the vacuum insulator by reacting rapidly with moisture in the air initially.
- Examples of the active material for adsorption include at least one selected from the group consisting of inorganic phosphorus compounds, metal oxides, metal halides, inorganic acid salts of metals, organic acid salts, and porous inorganic compounds, preferably calcium oxide (CaO), barium oxide (BaO), magnesium oxide (MgO), strontium oxide (SrO), and at least one member selected from the group consisting of aluminum oxide (Al 2 O 3 ).
- the active material for adsorption of the present invention may be made of calcium oxide (CaO).
- CaO calcium oxide
- the getter material of the present invention an active material for adsorption composed of only calcium oxide capable of removing 25 to 35% of its own weight is inserted.
- Calcium oxide can contain a much larger amount of moisture than conventional silica gel or the like, as can be seen from the reaction formula of CaO + H 2 O-> Ca (OH) 2 .
- calcium oxide not only can stably remove moisture in vacuum even at room temperature, but also has the advantage of being very inexpensive. That is, calcium oxide can stably remove moisture, but it can be seen that various gases can also be removed by adsorption depending on the type of calcium oxide. Therefore, even if the active material for adsorption of the getter material is composed only of calcium oxide, high heat insulating performance can be obtained.
- the specific surface area of the getter material can be increased by making the active material for adsorption into powder, and the particle size can be selected when the active material for adsorption is made into powder to adjust the adsorption rate suitable for gas permeability of the shell material. .
- the adsorption load of the getter material becomes constant, and the reliability of maintaining the performance of the vacuum insulator is improved.
- the adsorption active material powder increases, the specific surface area decreases and the reactivity decreases.
- the adsorption active material is calcium oxide
- the diameter of the powdered calcium oxide is 1-50 ⁇ m. Can be. If it is out of the above range, the moisture or gas penetrated into the vacuum insulator loses the opportunity to come into contact with calcium oxide, and thus the efficiency of removing the moisture or gas may be reduced. It is particularly preferable not to exceed 1 mm, since a sufficient amount of calcium oxide cannot be contained in the getter material container.
- the core part including the core material and the getter material is covered by an outer material, and the core part, that is, the inside of the outer material may be formed under a reduced pressure or a vacuum state.
- the core is formed inside the core portion, and the material constituting the core is not particularly limited. That is, in the present invention, all materials commonly used in the field of manufacturing vacuum insulation may be used.
- the kind of core material used for a vacuum heat insulating material is an inorganic or organic material with low thermal conductivity and little gas generation, and most of the above general materials can be used in this invention.
- the core material examples include one or more selected from the group consisting of polyurethane, polyester, glass fiber, polypropylene, polyethylene, and the like. Such materials can be used as cores in fibers, foams or other forms (eg glass wool).
- the shape, size and thickness of the core material is not particularly limited, and may be appropriately changed depending on the application to which the vacuum insulator is applied.
- the present invention comprises the steps of (a) acid treatment of any one of calcium carbonate, barium carbonate, magnesium carbonate, aluminum carbonate or strontium carbonate to selectively elute the cation; (b) extracting the eluted cation; And (c) calcining any one of the calcium carbonate, barium carbonate, magnesium carbonate, aluminum carbonate, or strontium carbonate from which the cation is extracted, to provide a method for preparing an active material for adsorption.
- the calcium carbonate used in the present invention is characterized in that it is derived from limestone.
- the limestone may contain silicon dioxide, alumina, magnesia and the like as impurities.
- the limestone is a sedimentary rock mainly composed of calcium carbonate, and has a white, gray or dark gray color and black color and forms a mass or a layer.
- the active material for adsorption of the present invention by using limestone as a main raw material, it is possible to obtain a high specific surface area calcium oxide, which can contribute to the provision of a getter material containing the calcium oxide and a vacuum insulation material comprising the same.
- the acid treatment is characterized in that using a weak acid.
- a weak acid such as hydrochloric acid and nitric acid
- impurities present in calcium carbonate and the like are eluted at the same time.
- strong acid such as hydrochloric acid and nitric acid
- impurities present in calcium carbonate and the like are eluted at the same time.
- magnesium having similar characteristics as calcium can be eluted with calcium when strong acid is used. Therefore, purity can be reduced. Can be eluted.
- the weak acids used above are organic acids such as lactic acid, citric acid, malic acid, malic acid, oxalic acid, acetic acid, tartaric acid, and adipic acid.
- adipic acid, succinic acid, maleic acid, glutamic acid, fumaric acid, pyruvic acid, gluconic acid, satric acid , Picric acid, aspartic acid, terebic acid, etc. may be included, citric acid in the aspect of maintaining the purity of the cation to be extracted to achieve the object of the present invention constant It is preferable to use.
- the step of extracting the eluted cation may be within 30 minutes extraction time.
- the cation extraction time is a certain time or more, the cation is preferably dissolved within 5 to 30 minutes in terms of recrystallization.
- the calcium extraction rate tends to increase slightly as the time increases up to about 30 minutes under the conditions of the present invention, but if it exceeds 30 minutes, the extraction rate decreases drastically. This is because, after a certain time, the cations dissolved in the weak acid form recrystallization, thereby reducing the amount of cations extracted.
- the step of firing any one of the calcium carbonate, barium carbonate, magnesium carbonate, aluminum carbonate or strontium carbonate from which the cation is extracted the firing temperature is 900 to 1000 ° C., the firing time is 1 to 2 hours. You can do
- step (c) to any one of calcium carbonate, barium carbonate, magnesium carbonate or strontium carbonate through the acid treatment step to extract the cation, and filter the extracted cation with a filter paper and then drying the step Then, the dried product is fired.
- the calcium oxide in the firing step when manufacturing the calcium oxide in the firing step, when firing at a long time or a high temperature there is a fear that the quality is reduced because the reactivity is reduced by grain growth. Therefore, it is important to calcinate for a short time at low temperature in order to obtain a high quality lime product.
- the firing holding time is preferably within 2 hours. Further, by setting the firing time to within 2 hours, crystal growth can be suppressed, and a high quality, high specific surface area active material having a uniform particle distribution can be obtained.
- the firing holding time is within 2 hours.
- the reaction when calcining calcium carbonate from which calcium ions were extracted, the reaction was terminated at about 750 ° C. when CaCO 3 was thermally analyzed (TG-DTA). At this temperature, CaCO 3 was unbaked. Since there is a concern, the firing temperature can be 900 ° C or higher to give sufficient energy. In addition, when the firing temperature exceeds 1000 ° C it is underestimated to cause agglomeration between particles, so the firing temperature is preferably 900 to 1000 ° C.
- the firing temperature is less than 900 °C, calcium carbonate and the like may not sufficiently react and remain as impurities, and when the firing temperature exceeds 1000 °C, the quality of the degradation due to the flocculation phenomenon due to grain growth. there is a problem.
- the temperature increase rate is increased to obtain fine particles, and a powder-like adsorption active material having a diameter of 1 to 5 mm can be produced.
- the active material for adsorption prepared by the above-mentioned manufacturing method is characterized in that the specific surface area is 5 ⁇ 40m 2 / g.
- a citric acid solution having a pH of 0 was prepared by mixing 200 g of water with 30 g of citric acid.
- the citric acid solution prepared above was added to a solution in which 30 g of solid calcium carbonate was sufficiently dispersed in 300 g of water, and calcium ions were selectively eluted out.
- the extraction time was 30 minutes, filtered through filter paper and dried for 1 hour at 130 °C drying oven.
- the dried product was calcined at 900 ° C. for 1 hour to prepare a powdered calcium oxide getter material having a specific surface area of 15 m 2 / g and a diameter of 10 ⁇ m.
- a citric acid solution having a pH of 0 was prepared by mixing 200 g of water with 30 g of citric acid.
- the citric acid solution prepared above was added to a solution in which 30 g of barium carbonate in a solid powder state was sufficiently dispersed in 300 g of water, and barium ions were selectively eluted.
- the extraction time was 10 minutes, filtered with filter paper and dried for 1 hour at 130 °C drying oven.
- the dried product was calcined at 1000 ° C. for 2 hours to prepare a barium oxide getter material having a specific surface area of 40 m 2 / g and a diameter of 15 ⁇ m.
- Calcium oxide (commercial reagent, JUNSEI) with a specific surface area of 3 m 2 / g was used.
- Calcium oxide (commercial reagent, Sungwon material) having a specific surface area of 4 m 2 / g was used.
- Example 2 the moisture absorption rate was increased after 1 hour and 30 minutes, whereas in Example 1, about 8% by weight after 30 minutes, and in Example 2, about 5% by weight after 30 minutes had passed. Showed an increase. As a result, when the specific surface area increases by about 10 times, the rate of reaction of calcium oxide with water increases by 5 to 10 times.
- Example 1 when the moisture absorption rate was measured after 7 hours, Example 1 was about 35% by weight, Example 2 was about 33% by weight, Comparative Example 1 was about 2% by weight, and Comparative Example 2 was about 3% by weight. As time passed, the gap of reaction rate was larger. In conclusion, the larger the specific surface area, the greater the number of active sites that can be reacted.
- Example 1 and Comparative Example 2 were left to stand for 6 hours in a temperature of 40 °C, 70 °C, 50% RH atmosphere, the moisture absorption was calculated, the results obtained are shown in Table 2 below. The moisture absorption rate at this time was computed by the said [General formula 1].
- Example 1 which has a relatively high specific surface relative to Comparative Example 2, was generally excellent in the moisture absorption rate.
- the increase in the moisture absorption rate was even higher in the case of Example 1.
- the getter material containing calcium oxide having a high specific surface area showed better hygroscopic performance.
- a core material consisting of a glass board was prepared in a size of 8x190x250mm (thickness x width x length) and 90 g, and then used as a core material for vacuum insulation.

- a getter material prepared by placing 5 g of calcium oxide having a purity of 100% in a pouch was included in the core material for vacuum insulation.
- the core insulation material for vacuum insulation was inserted into an encapsulation body, and sealed in a vacuum state of 10 Pa to prepare a vacuum insulation material according to the present invention, and aged at 75 ° C. to measure the results in units of 1 hour.
- Example 1 when Example 1 was applied, an initial thermal insulation performance of 0.2 mW / mK was improved on average for each time compared to Comparative Example 1.
- Example 1 since the thermal conductivity is not stabilized even after aging at 75 ° C. for 3 hours, an aging time of at least 3 hours is required, whereas Comparative Examples 1 and 2 show stable thermal conductivity values from 1 hour after aging. It was. When high energy was applied to the getter material having a fast reaction rate, the adsorption performance was stabilized in 1 hour.
- Comparative Example 1 required aging at 75 °C for the activation of the getter material, but in the case of Example 1 even if aged at 30 ⁇ 40 °C aging at 75 °C Similar initial performance could be achieved. As a result, the reaction rate was accelerated due to the high specific surface area, which means that less energy is consumed to activate the getter material.
