Abstract
Description
本発明は、酸化マグネシウム、塩化マグネシウム、酸化アルミニウム、二酸化珪素を配合して成る造形用または建築用の無機質組成物およびその製造方法に関する。 TECHNICAL FIELD The present invention relates to an inorganic composition for molding or construction comprising magnesium oxide, magnesium chloride, aluminum oxide and silicon dioxide, and a method for producing the same.
（ａ）ＦＲＰは、ガラス繊維、カーボン繊維などの繊維類に、ポリエステル樹脂,エポキシ樹脂などの樹脂類を含侵、硬化させて製造される繊維強化プラスチックである。後述する表４に示すように、比重が小さく、圧縮強度が大きいことから、軽量で、折損し難く、柔軟性を保持した材料であることは一般に良く知られている。この特徴を生かして、ＦＲＰは遊園地や公園の擬岩、美術工芸品あるいは建築物の装飾柱などに利用されている。
しかしながら、ＦＲＰなどプラスチック製品は腐敗しないので、劣化した場合には燃焼させる廃棄方法が取られて、その結果、有毒ガスが発生したり、又、使用中にも揮発性有機化合物ＶＯＣが形成されて、環境を悪化させる原因となっている。
(A) FRP is a fiber reinforced plastic manufactured by impregnating and curing resins such as polyester resin and epoxy resin in fibers such as glass fiber and carbon fiber. As shown in Table 4 to be described later, since the specific gravity is small and the compressive strength is large, it is generally well known that the material is lightweight, hardly broken, and retains flexibility. Taking advantage of this feature, FRP is used for amusement parks, park rocks, arts and crafts, and decorative pillars of buildings.
However, plastic products such as FRP do not rot, so if they are deteriorated, they are disposed of by burning. As a result, toxic gases are generated and volatile organic compounds VOC are formed during use. , Causing the environment to deteriorate.
（ｂ）一方、本出願人は、材料がガラス繊維補強石膏（ＧＲＧ）やガラス繊維補強セメント（ＧＲＣ）を扱っており、この材料は、石膏やコンクリートの無機質にガラス繊維等を加えたものである。このＧＲＧやＧＲＣの物性は、前記表４に示す通りで、美術館などでは優美な装飾品や造形品として演出されたり、天井埋め込み型間接照明用天井装飾材や、ローマ柱等として三次曲面に対応した内装工事が施工され、市場に提供されている。
しかし、これをそのまま前記ＦＲＰの代替品として利用しようとすると、比重が大きいので、重量物となって施工性が悪く、且つ、石膏を原料に含むＧＲＧでは水に可溶となり、屋外での使用に耐えられない等の問題点が残される。
(B) On the other hand, the present applicant handles glass fiber reinforced gypsum (GRG) and glass fiber reinforced cement (GRC), and this material is obtained by adding glass fiber or the like to a mineral of gypsum or concrete. is there. The physical properties of GRG and GRC are as shown in Table 4 above. They are produced as elegant decorations and moldings at museums, etc., and are compatible with cubic curved surfaces as ceiling decoration materials for ceiling-mounted indirect lighting, Roman pillars, etc. Interior work has been done and is being offered to the market.
However, if this is used as a substitute for the FRP as it is, the specific gravity is large, so it becomes heavy and poor in workability, and GRG containing gypsum as a raw material becomes soluble in water and is used outdoors. Problems such as inability to withstand.
（ｃ）これに対し従来技術には、無機質で軽量であり、且つ、厚さの薄い構造物が特許文献１に提案されている、
即ち、酸化マグネシウムと塩化マグネシウムと硫酸カルシウムも組成の一つとしたカルシウム化合物とを常温常圧且つ、強酸の存在化で混合して１２時間以上で造形し、マグネシウム・カルシウム構造体を形成している。
しかし、当該技術を上記ＦＲＰの代替品として使用しようとすると、（イ）該構造体の骨格を形成するカルシウム化合物は、構造体の歪を抑える働きがあり、強固な構造体であるが、石膏と同様にカルシウム化合物であるため、雨水などを吸収して溶解し易い性質を有する。従って、屋内品などの用途に限定され、屋外の利用には不向きとなっている。（ロ）また、マグネシウム・カルシウム構造体を形成するときに添加される強酸は、該構造体のｐＨを小さくしてしまい、この構造体で製造された建築材料は劣化が早く、鉄筋など金属を錆びさせてしまう、等の欠点が生じてしまう。
That is, magnesium oxide, magnesium chloride, and calcium compound, which is one of the compositions, are mixed at room temperature and normal pressure in the presence of a strong acid and shaped in 12 hours or more to form a magnesium / calcium structure. .
However, when the technology is used as a substitute for the FRP, (a) the calcium compound forming the skeleton of the structure has a function of suppressing the distortion of the structure and is a strong structure. Since it is a calcium compound, it has the property of easily absorbing and dissolving rainwater. Therefore, it is limited to uses such as indoor products and is not suitable for outdoor use. (B) In addition, the strong acid added when forming the magnesium / calcium structure lowers the pH of the structure, and the building materials manufactured with this structure are rapidly deteriorated. Defects such as rusting occur.
本発明は上記実情に鑑みてなされたもので、（１）廃棄物の問題が生じないような無機質で、（２）比較的比重が小さく強靱性を備え、（３）水に難溶性となるようカルシウム化合物を配合することなく、（４）発錆を促進する強酸を使用しないで、常温常圧下で且つ短時間で弱アルカリ性製品を造形し得るＦＲＰに近づく性能を備えた製品の成型技術を提供するものである。 The present invention has been made in view of the above circumstances, and (1) it is an inorganic material that does not cause the problem of waste, (2) it has a relatively small specific gravity and has toughness, and (3) it is hardly soluble in water. (4) Without using a strong calcium compound that promotes rusting, and using a molding technology for products that are close to FRP that can form weakly alkaline products in a short time under normal temperature and pressure without using strong acids. It is to provide.
上記目的を達成するために、請求項１記載の造形用または建築用の無機質組成物は、酸化マグネシウム２０〜６０重量％、塩化マグネシウム５〜４０重量％、酸化アルミニウム５〜４０重量％、二酸化珪素５〜３０重量％を配合して成ることを特徴とする。 In order to achieve the above object, the inorganic composition for modeling or construction according to claim 1 comprises 20 to 60% by weight of magnesium oxide, 5 to 40% by weight of magnesium chloride, 5 to 40% by weight of aluminum oxide, and silicon dioxide. It is characterized by comprising 5 to 30% by weight.
請求項２記載の造形用または建築用の無機質組成物の製造方法は、酸化マグネシウム２０〜６０重量％、塩化マグネシウム５〜４０重量％、酸化アルミニウム５〜４０重量％、二酸化珪素５〜３０重量％を配合混合して型に流し込み、比較的肉薄な三次曲面を常温常圧下で形成することを特徴とする。 The manufacturing method of the inorganic composition for shaping | molding of Claim 2 or a building is magnesium oxide 20-60 weight%, magnesium chloride 5-40 weight%, aluminum oxide 5-40 weight%, silicon dioxide 5-30 weight% Is mixed and poured into a mold to form a relatively thin cubic surface under normal temperature and pressure.
本発明の造形用または建築用組成物は、各配合材料の比重が小さいので、軽量の無機質組成物を形成することができる。ガラス繊維を配合剤に入れないでも強度が出る。水に溶解するカルシウム化合物を使用していないので、雨水が掛かる屋外でも使用できる。また、組成物は弱アルカリ性を保持し、また、硫酸や塩酸など酸を使わない結晶化反応であるので、組成物の劣化がなく、鉄筋など金属を錆びさせることはない。
その製造方法は、酸化アルミニウムや二酸化珪素を配合し、焼成しないで、常温常圧下で結晶化反応が徐々に進行するので、急激な膨張、収縮や歪みがなく、且つ強度が大きい組成物を形成することができる。更に、酸化マグネシウムと二酸化珪素が多いので、質感は天然石に似た光沢のある白色を示す。天然石に似ているので緻密であり、磨くと光沢が増す。
また三次曲面を有する型に流し込むので、三次曲面や彫刻などあらゆる形を自由に作り出せる。厚さ５〜８ｍｍ、直径３０００ｍｍの三次曲面を容易に形成することができる。
Since the specific gravity of each compounding material is small in the composition for modeling or building of the present invention, a lightweight inorganic composition can be formed. Even if glass fiber is not included in the compounding agent, strength is increased. Since it does not use a calcium compound that dissolves in water, it can also be used outdoors where rainwater is applied. Further, since the composition retains weak alkalinity and is a crystallization reaction that does not use an acid such as sulfuric acid or hydrochloric acid, the composition does not deteriorate and does not rust metals such as reinforcing bars.
The production method is blended with aluminum oxide or silicon dioxide, and without firing, the crystallization reaction gradually proceeds under normal temperature and normal pressure, so that a composition having no large expansion, contraction or distortion and high strength is formed. can do. Furthermore, since there are a lot of magnesium oxide and silicon dioxide, the texture shows a glossy white similar to natural stone. It resembles natural stone and is dense.
Moreover, since it is poured into a mold having a cubic surface, all shapes such as a cubic surface and engraving can be freely created. A cubic curved surface having a thickness of 5 to 8 mm and a diameter of 3000 mm can be easily formed.
そこで本発明は、自然界に存在あるいは安価に購入できる金属酸化物や金属塩化物を配合し、造形用または建築用の無機質組成物として一体化するが、その製造方法を以下に説明する。
最初に、本発明では、造形用または建築用組成物として、酸化マグネシウム、塩化マグネシウム、酸化アルミニウム、二酸化珪素の全てを用いることとし、これに言及する。
Therefore, in the present invention, a metal oxide or a metal chloride that exists in nature or can be purchased at a low cost is blended and integrated as an inorganic composition for modeling or building. The manufacturing method will be described below.
First, in the present invention, magnesium oxide, magnesium chloride, aluminum oxide, and silicon dioxide are all used as a molding or building composition, and this is referred to.
先ず、各選定材料の特徴について記述する。
酸化マグネシウムの配合量は２０〜６０重量％で、配合剤のなかでは最も多い。酸化マグネシウムは、組成物の白さを出す配合剤であり、その白さを際立たせるために配合量を多くする。また、組成物とりわけ二酸化珪素が溶ける温度を低くするので、固溶体を形成し易くすると共に、引いては、緻密で光沢のある天然石状に一体化する働きをする。更に、水にはわずかしか溶けないので、形成される組成物は屋外においても、使用可能であり、風化し難い。
次に、塩化マグネシウムの性状は、色は白色で固体であるが、６水和物であるので吸湿性が強く液状に成り易い。本発明を構成する他の組成材料の沈殿防止剤であると共に、中性〜弱アルカリ性に調整する調整剤である。その結果、組成物の化学反応を進み易くする機能を有し、酸化マグネシウム、酸化アルミニウム、二酸化珪素を結合させる接着剤的な働きを行う。その配合量は、５〜４０重量％である。
三つ目の酸化アルミニウムの配合量は５〜４０重量％で、他の組成材料と反応して、強固な組成物を形成するための骨格となる。５〜４０重量％としたのは、５重量％以下の過小量であったり、４０重量％以上の過多な量であると、酸化アルミニウムは解け難く、脆い組成物となってしまうからである。また、組成物として一体化できたとしてもひびが入り易いからである。
四つ目の二酸化珪素は骨材であり、その配合量は５〜３０重量％とした。二酸化珪素はガラス質の原料であり、艶のある柔らかい質感を出現させる材料である。二酸化珪素配合量が５〜３０重量％であると白色〜乳白色を呈し、融点を上昇させ、ひび割れ防止効果が出てくる。しかし、配合量が３０重量％超とすると溶け難くなり、不透明になってひび割れが起きる。５重量％未満では解けすぎてしまう。
First, the characteristics of each selected material will be described.
The compounding amount of magnesium oxide is 20 to 60% by weight, which is the largest among the compounding agents. Magnesium oxide is a compounding agent that brings out the whiteness of the composition, and the blending amount is increased in order to make the whiteness stand out. In addition, since the temperature at which the composition, particularly silicon dioxide, melts is lowered, it facilitates the formation of a solid solution and, in turn, functions to be integrated into a dense and glossy natural stone. Furthermore, since it is only slightly soluble in water, the composition formed can be used outdoors and is not easily weathered.
Next, the properties of magnesium chloride are white and solid, but since it is hexahydrate, it is highly hygroscopic and tends to be liquid. In addition to being a precipitation inhibitor for other composition materials constituting the present invention, it is a regulator for adjusting to neutral to weak alkalinity. As a result, it has a function of facilitating the chemical reaction of the composition, and functions as an adhesive for bonding magnesium oxide, aluminum oxide, and silicon dioxide. The blending amount is 5 to 40% by weight.
The compounding amount of the third aluminum oxide is 5 to 40% by weight, and becomes a skeleton for reacting with other composition materials to form a strong composition. The reason why it is set to 5 to 40% by weight is that if it is an excessive amount of 5% by weight or less or an excessive amount of 40% by weight or more, the aluminum oxide is difficult to dissolve and becomes a brittle composition. Moreover, even if it can be integrated as a composition, it is easy to crack.
The fourth silicon dioxide is an aggregate, and its blending amount is 5 to 30% by weight. Silicon dioxide is a glassy raw material and is a material that makes a glossy and soft texture appear. When the blending amount of silicon dioxide is 5 to 30% by weight, white to milky white color is exhibited, the melting point is raised, and the effect of preventing cracks appears. However, if the blending amount exceeds 30% by weight, it becomes difficult to dissolve, and it becomes opaque and cracks occur. If it is less than 5% by weight, it will unravel too much.
製造方法としては、各配合剤をポリエチレン製の容器に入れ、撹拌する。更に、水を加えながら良く混合した後、型に流し込む。常温常圧下で乾燥させて５〜８ｍｍ厚さとして、ひび割れを発生しないセラミック組成物を生成した。この組成物は、比較的肉薄な三次曲面を形成することが可能となった。ここで、本発明でいう三次曲面とは、多くは、湾曲した凹凸のある立体的な形状を指すが、表面が平坦な壁材等も含める意である。
また、本配合剤にガラス繊維を混ぜれば、更なる補強ができる。高炉スラグも配合剤として添加することも可能である。
As a manufacturing method, each compounding agent is put in a polyethylene container and stirred. Further, mix well while adding water, then pour into the mold. The ceramic composition which does not generate | occur | produce a crack was produced | generated by making it dry under normal temperature normal pressure to 5-8 mm thickness. This composition can form a relatively thin cubic surface. Here, the cubic curved surface as used in the present invention means a three-dimensional shape with curved irregularities, but it is meant to include a wall material having a flat surface.
Moreover, if glass fiber is mixed with this compounding agent, further reinforcement can be performed. Blast furnace slag can also be added as a compounding agent.
この発明の実施例を、上記実施の形態に基づいて製作した。その実施状況を表１、表２および表３に従って説明する。 An example of the present invention was manufactured based on the above embodiment. The implementation status will be described according to Table 1, Table 2, and Table 3.

Table 2 shows a comparative blending table for forming an inorganic composition for modeling or building manufactured based on the above-described form. Compared with Example 1, the amount of magnesium oxide was reduced and the amount of aluminum oxide was increased.
In a polyethylene container, 30 g (20.7 wt%) magnesium oxide, 30 g (20.7 wt%) magnesium chloride, 40 g (27.6 wt%) aluminum oxide, and 10 g (6.9 wt%) silicon dioxide Mix and charge 35 g (24.1 wt%) of water with stirring with a glass spoon. Then, it was poured into a mold having a cubic curved surface and left at room temperature and normal pressure for 20 hours to dry and demold. As a result, the resulting composition became a white ceramic composition with a thickness of 5 mm and was not glossy. The specific gravity increased to 1.9, and the compressive strength decreased to 20.0 N / mm 2 .
上記の形態に基づいて製作した造形用または建築用の無機質組成物を形成するための比較配合表を表３に示す。実施例１に比べて酸化マグネシウム量を減らし、二酸化珪素量を増量した。
ポリエチレン製の容器に、酸化マグネシウム３０ｇ（２０．７重量％）、塩化マグネシウム３０ｇ（２０．７重量％）、酸化アルミニウム３５ｇ（２４．１重量％）、二酸化珪素１５ｇ（１０．３重量％）を混合し、ガラスさじで撹拌しながら水３５ｇ（２４．１重量％）を投入する。その後、三次曲面を有する型に流し込み、常温常圧で２０時間放置し、乾燥脱型させた。その結果、生成した組成物は滑りのある質感で、厚さ５ｍｍで艶のある白色〜乳白色セラミック組成物が形成できた。比重は１．７と小さくなり、圧縮強度は３１．２Ｎ／ｍｍ２と大きくなった。
Table 3 shows a comparative blending table for forming an inorganic composition for modeling or building manufactured based on the above-described form. Compared with Example 1, the amount of magnesium oxide was reduced and the amount of silicon dioxide was increased.
In a polyethylene container, 30 g (20.7 wt%) of magnesium oxide, 30 g (20.7 wt%) of magnesium chloride, 35 g (24.1 wt%) of aluminum oxide, and 15 g (10.3 wt%) of silicon dioxide Mix and charge 35 g (24.1 wt%) of water with stirring with a glass spoon. Then, it was poured into a mold having a cubic curved surface and left at room temperature and normal pressure for 20 hours to dry and demold. As a result, the produced composition had a slippery texture, and a glossy white to milky white ceramic composition with a thickness of 5 mm could be formed. The specific gravity decreased to 1.7 and the compressive strength increased to 31.2 N / mm 2 .
この発明の試験例を、上記実施の形態に基づいて製作した造形用または建築用の無機質組成物の試験状況を表４および図１に従って説明する。 A test example of the inorganic composition for modeling or building manufactured based on the above embodiment will be described with reference to Table 4 and FIG.
上記の形態に基づいて製作した造形用または建築用の無機質組成物、ＦＲＰおよび天然石の物性比較を比重の小さい物から順に並べた。その結果を表４に示す。
本発明の造形用または建築用組成物の実施例３種の比重は、ＦＲＰにほぼ等しいので、軽量であることを表している。圧縮強度はＦＲＰのほぼ２倍であるので、ＦＲＰのような可撓性はないが、強固であることを示している。また、ＦＲＰと同様にガラス繊維を配合したＧＲＧやＧＲＣの比重は、基本配合剤の石膏やポルトランドセメントの影響により本実施例やＦＲＰより大きく、圧縮強度は本実施例とＦＲＰの中間位の値を示していることから、ＧＲＧやＧＲＣはセラミック特有の重さがＦＲＰに替われなかったことを表している。
また、本発明の硬度が天然石とほぼ同じであることから、天然石に似た光沢のある白色質感を示す。天然石に似ているので緻密であり、磨くと光沢が増す。
上記を要約すると、本発明は比重が小さくＦＲＰ程度であり、硬度、圧縮強度が大きいので、軽くて硬く、折れ難い材料となっていることを示している。
The physical property comparison of the inorganic composition for modeling or building, FRP and natural stone produced based on the above-mentioned form was arranged in order from the thing with small specific gravity. The results are shown in Table 4.
The specific gravity of Example 3 of the molding or building composition of the present invention is almost equal to FRP, which means that it is lightweight. Since the compressive strength is almost twice that of FRP, it is not flexible like FRP, but is strong. In addition, the specific gravity of GRG or GRC containing glass fiber as in FRP is larger than that of this example or FRP due to the influence of gypsum or Portland cement as a basic compounding agent, and the compressive strength is an intermediate value between this example and FRP. Therefore, GRG and GRC indicate that the weight peculiar to ceramics was not replaced by FRP.
Moreover, since the hardness of this invention is substantially the same as a natural stone, the glossy white texture similar to a natural stone is shown. It resembles natural stone and is dense.
Summarizing the above, the present invention shows that the specific gravity is small and about FRP, and the hardness and the compressive strength are large, so that the material is light, hard and not easily broken.
上記の形態に基づいて製作した本発明の造形用または建築用組成物と石膏をそれぞれ１辺５ｃｍの立方体に成形した後、水に投入して、溶解試験を行った。
その結果を図１に示す。
２０℃の水を張った２ケのプラスチック製のボウル（直径２８ｃｍ）に、本発明の実施例１と石膏をそれぞれ投入し、３０日毎にその重量を計量した。計量にあたり、水から取り出した試験体は５分間、ドライヤーにて乾燥した。試験は９０日間行い、試験体の溶融状況を比較した。
その結果、本発明の組成物には重量変化がなく、９０日間継続して２２５ｇを示し、ボウル内の水の白濁もなかった。劣化が全く起きていないことを示し、水に強い組成物であることを表している。一方、石膏は、試験前後で重量変化があり、試験前に２９０ｇであった試験体が９０日後には２１０ｇに減少した。その減少率は２７．６％であった。更に、ボウル内の水は白濁し、試験体の表面にザラザラ感が現れた。また試験体の角などは簡単に崩れてしまい、劣化が進行していることを示している。
The molding or building composition of the present invention produced based on the above form and gypsum were each molded into a cube of 5 cm on each side, and then poured into water to conduct a dissolution test.
The result is shown in FIG.
Example 1 of the present invention and gypsum were put into two plastic bowls (diameter 28 cm) filled with water at 20 ° C., and their weights were weighed every 30 days. In weighing, the test specimen taken out of water was dried with a dryer for 5 minutes. The test was conducted for 90 days, and the melting conditions of the specimens were compared.
As a result, the composition of the present invention showed no weight change, showed 225 g continuously for 90 days, and had no cloudiness of water in the bowl. This indicates that no deterioration has occurred and the composition is strong against water. On the other hand, the gypsum had a weight change before and after the test, and the test specimen, which was 290 g before the test, decreased to 210 g after 90 days. The rate of decrease was 27.6%. Furthermore, the water in the bowl became cloudy, and a rough feeling appeared on the surface of the specimen. In addition, the corners of the specimen easily collapse, indicating that the deterioration is progressing.
本発明は、ＦＲＰの代替品としての使用が可能で、例えば遊園地や公園の擬岩、美術工芸品あるいは装飾柱などの一般建築物にも利用できる。 The present invention can be used as a substitute for FRP, and can also be used for general buildings such as amusement parks, park rocks, arts and crafts, and decorative columns.
