Description

【０００１】
【発明の属する技術分野】
本発明は、炭粉含有の熱可塑性合成樹脂線状体で織られたスクリーン、簾に関するものである。
【０００２】
【従来の技術】
熱可塑性合成樹脂による中空線状体を織り、または編み上げたものをスクリーン、簾にしたものはあるが炭粉を合成樹脂に練り込み、成形してなる熱可塑性合成樹脂線状体で作られたスクリーン、簾は無い。そこで炭の持つ様々な機能を付加したスクリーン、簾にしようとするものである。
【０００３】
【発明が解決しようとする課題】
炭の持つ機能には吸湿性、放湿性、吸着脱臭性、プラスイオン吸着性等々があるがこれらは炭の持つ微細孔の働きによるところが大きい。ところが炭粉を合成樹脂に練り込み、成形すると樹脂に覆われ、機能が低下する恐れが生じてくる。従ってこのような問題を解決するためには出来るだけ炭粉含有量を多くすることと、成形物の表面面積を拡大して炭粉の微細孔が直接空気に触れる部分を多くすることが炭の持つ機能を低下させないために必要であると考えるものである。
【０００４】
【課題を解決するための手段】
本発明は、スクリーン、簾の横糸となる炭粉含有の熱可塑性合成樹脂線状体において発泡することや炭粉の粒子径の調整を行うことにより連続発泡孔や貫通発泡孔など微細凹凸孔を設けたもので、炭粉含有の熱可塑性合成樹脂線状体の表面面積や空洞部面積を炭粉を含まない無発泡の熱可塑性合成樹脂線状体に比較して１．５〜数十倍にまで調整拡大することに成功したものである。
【０００５】
炭と合成樹脂（熱可塑性樹脂）を混合し、押出成形した場合、炭は溶融しないので炭粉は粒子状態で樹脂中に被覆状態で存在するか、部分的に頭を出したように樹脂にくっ付いた状態になっている。従って成形物の表面では凹凸状となり、押出成形時の流れがあるので凸部の流れ方向の後ろ側に流星の尾のような微細孔を形成する。
【０００６】
炭粉の粒子径分布は０．５〜１２０μｍであるがその内、比較的分布量の多い５〜５０μｍのものを調整配合することにより、表面の凹凸の大きさや微細孔の状態を調整することが出来る。さらに発泡することによってより複雑な連続発泡孔や貫通発泡孔を設けることで内部（肉厚部）にも空気に触れる空洞部が出来、その面積は数十倍にまで拡大することが出来るのである。
【０００７】
発泡の方法について水分調整法による場合を述べると炭粉の吸湿性の高いことを利用するもので成形前の乾燥段階で水分調節を行い、望む発泡状態を形成するのである。
【０００８】
【発明の実施の形態】
次に、本発明の実施の形態について実験結果を例にあげて説明する。
実施例において各材料や加工の条件は次の通りである。炭粉の素の炭はセラミック炭と備長炭を使用した、セラミック炭はチップ状の杉１０〜６０％、檜１０〜６０％、松１０〜６０％の間で調整配合し、１００部にしたものに無機質粘結材３〜１５部を水溶性糖類で混練りしたものを炭化炉で炭化温度６００〜１０００度で炭化し、さらに粉砕機で０．５〜１２０μｍの粒子径の炭粉にした、また備長炭は和歌山産の姥目樫（馬目樫）を１０００〜１２００度で焼いた炭を粉砕機で０．５〜１００μｍの粒子径の炭粉にした。
【０００９】
熱可塑性樹脂はポリオレフィン系樹脂が炭粉との混合において好ましい。炭粉との配合は炭粉３〜７０％が可能であるが実施上は５〜５０％が好ましい、従って樹脂は９７〜３０％となり、実施上は９５〜５０％が好ましく、ポリエチレンＬＤ、ＬＬＤ、メタロセン触媒ポリエチレン、ポリプロピレン等をこの範囲で１〜３種を配合した。
【００１０】
発泡を形成するには有機系、無機系発泡剤による発泡、ガス発泡、水発泡等が考えられるが実施例では有機系発泡剤を選択した、アゾジカルボンアミドを０．２５〜１．０％で調整した。尚、スクリーン、簾について、スクリーンは図２のように綿糸や合成繊維等の細い糸を縦糸にして炭粉含有の熱可塑性合成樹脂線状体を横糸として使い薄く織り込みスクリーン状に透けて見えるようにしたものである。また、簾は簾編み機により、炭粉含有線状体を綿糸等の縦糸を使って簾状に編み上げたものである。
【００１１】
次に炭粉含有の熱可塑性合成樹脂線状体の形状については図４の中空線状体、図５の中実線状体、図６の襞付線状体などを言う。また、規格においては直径、３〜５ｍｍ、長さは１８５ｃｍの中空線状体とし、簾編み機で二枚取りの編み物にし、天地に部品を付け、シングル幅９０×１５０ｃｍの簾とダブル幅の１８０×１５０ｃｍの簾にした。またスクリーン用の線状体においては直径１．０〜３．０ｍｍ長さは９８ｃｍの中空線状体とし、花莚織機で向こうが透けて見えるような織り方にし、縦糸で柄を入れたものや入れない無地調など、９０×１５０ｃｍのスクリーンに仕上げた。
【００１２】
中空線状体の成形加工は４０ｍｍ、Ｌ／Ｄ２６の押出成形機（日本製鋼製）にて実験成形をした。その内代表的な実施例を表１に示し、それらのテスト結果を表２とした。また、比較試料として炭粉を入れないものを実施例４として載せた。
【００１３】
【表１】

【表２】

【００１４】
実施例１〜２はセラミック炭の例である。また、実施例３は和歌山産備長炭の例である。実施例１において成形品の表面には細かな凹凸が多数出来た。さらに流星の尾が付いたような微細孔も観察された。中空線状体の内側の表面も同じような状態が観察された。
【００１５】
明らかに成形品の表面面積は増加している。実施例２においても同様に細かな凹凸が表面上に出来た。微細孔も観察されたが実施例１よりも大きなものが混在しており全体的に表面が荒っぽいものに感じられた。これは炭粉の粒子径によるものと考えられる。実施例３においても同様の状態が観察されたがその状態は実施例１に良く似ているが細かな凹凸が多く、鈍い艶消しの黒色をしていた。
【００１６】
【発明の効果】
上記実施例およびその試験結果が示すように凹凸や微細孔など連続発泡孔や貫通発泡孔などを設けたことで成形物の表面面積が拡大し、炭の持つ機能効果をより効果的に発揮すると共に炭粉の付着や飛散などを防ぎ、汚れの付かないスクリーンや簾にすることが出来たのである。
【００１７】
インテリア商品としてお部屋に吊って貰うだけで炭の持つ、消臭、脱臭機能や湿度、温度の調整機能、プラスイオンの吸着等空気浄化機能などが期待できる商品となったのである。
【００１８】
このように機能効果を高める配合や成形物の構造により本来、炭の持っている微細孔がより多く直接空気に触れる部分が多くなったため、炭の持つ機能の減衰を防ぎ、結果的に商品としての価値を大いに高めることが出来たのである。

BACKGROUND OF THE INVENTION
The present invention relates to a screen woven with a linear synthetic resin containing carbon powder, and a wrinkle.
[0002]
[Prior art]
Some are made by weaving or knitting hollow linear bodies made of thermoplastic synthetic resin into screens and cocoons, but they are made from thermoplastic synthetic resin linear bodies that are made by kneading and molding carbon powder into synthetic resin. There is no screen, no trap. Therefore, we are going to make a screen with various functions of charcoal.
[0003]
[Problems to be solved by the invention]
The charcoal has functions such as hygroscopicity, moisture release, adsorptive deodorization, positive ion adsorbing, etc., but these are largely due to the function of the fine pores of charcoal. However, when carbon powder is kneaded into a synthetic resin and molded, it is covered with the resin, and the function may be deteriorated. Therefore, in order to solve such problems, it is necessary to increase the carbon powder content as much as possible and to enlarge the surface area of the molded product so that the fine pores of the carbon powder directly contact the air. This is considered necessary in order not to degrade the functions possessed.
[0004]
[Means for Solving the Problems]
In the present invention, fine uneven holes such as continuous foaming holes and through-foaming holes are formed by foaming in a linear powder of a thermoplastic synthetic resin containing carbon powder that becomes a weft yarn of a screen or cocoon, or by adjusting the particle diameter of the carbon powder. The surface area and cavity area of the carbonaceous powder-containing thermoplastic synthetic resin linear body are 1.5 to several tens of times that of the non-foamed thermoplastic synthetic resin linear body containing no carbon powder. It has succeeded in expanding and adjusting to.
[0005]
When charcoal and synthetic resin (thermoplastic resin) are mixed and extruded, the charcoal does not melt, so the charcoal powder exists in the resin in a coated state in the form of particles, or the resin appears to partially protrude They are stuck together. Accordingly, the surface of the molded product is uneven, and there is a flow during extrusion molding. Therefore, a microhole like a tail of a meteor is formed on the rear side in the flow direction of the convex portion.
[0006]
The particle size distribution of the charcoal powder is 0.5 to 120 μm, and among them, the size of the unevenness on the surface and the state of the fine pores are adjusted by adjusting and blending the one having a relatively large distribution amount of 5 to 50 μm. I can do it. Furthermore, by providing more complicated continuous foaming holes and through-foaming holes by foaming, the inside (thick part) can also be made a hollow part that touches air, and the area can be expanded to several tens of times. .
[0007]
The foaming method is based on the moisture adjustment method, which utilizes the high hygroscopicity of the carbon powder. The moisture is adjusted in the drying stage before molding to form the desired foamed state.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
Next, an embodiment of the present invention will be described by taking experimental results as examples.
In the examples, each material and processing conditions are as follows. The charcoal powder is made of ceramic charcoal and Bincho charcoal, and the ceramic charcoal is adjusted and blended between chip-shaped cedar 10-60%, firewood 10-60%, and pine 10-60% to make 100 parts. What was kneaded with 3-15 parts of an inorganic binder with water-soluble sugar was carbonized in a carbonization furnace at a carbonization temperature of 600-1000 ° C., and was further made into carbon powder with a particle size of 0.5-120 μm with a pulverizer. In addition, Bincho charcoal was obtained by burning charcoal baked from Wakayama at 1000-1200 degrees into charcoal powder having a particle size of 0.5-100 μm using a pulverizer.
[0009]
The thermoplastic resin is preferably a polyolefin resin when mixed with carbon powder. The blending with the charcoal powder can be 3 to 70% charcoal powder, but is preferably 5 to 50% in practice. Therefore, the resin is 97 to 30%, and practically 95 to 50% is preferred. Polyethylene LD, LLD 1 to 3 kinds of metallocene catalyst polyethylene, polypropylene, etc. were blended within this range.
[0010]
In order to form foaming, foaming with organic or inorganic foaming agents, gas foaming, water foaming, etc. can be considered, but in the examples, an organic foaming agent was selected, and azodicarbonamide was 0.25 to 1.0%. It was adjusted. As shown in Fig. 2, the screen and wrinkles are thinly woven using a thin synthetic yarn such as cotton or synthetic fiber as a warp and a carbon fiber-containing thermoplastic synthetic resin wire as a weft. It is a thing. The cocoon is a knitting machine made of carbon powder-containing linear bodies using a warp such as cotton yarn.
[0011]
Next, the shape of the thermoplastic synthetic resin linear body containing carbon powder refers to the hollow linear body in FIG. 4, the solid linear body in FIG. 5, the brazed linear body in FIG. In addition, the standard is a hollow linear body with a diameter of 3 to 5 mm and a length of 185 cm, a double knitting machine with a knitting machine, parts attached to the top and bottom, a single width of 90 × 150 cm and a double width of 180 A cocoon of 150 cm was used. The screen linear body is a hollow linear body with a diameter of 1.0 to 3.0 mm and a length of 98 cm, and weaves it so that the other side can be seen through with a flower weaving loom. It was finished on a 90 x 150 cm screen with plain color that could not be added.
[0012]
The hollow wire was molded by an experimental molding with an extrusion molding machine (manufactured by Nippon Steel Co., Ltd.) having a L / D of 40 mm. Typical examples are shown in Table 1, and the test results are shown in Table 2. Moreover, the thing which does not put charcoal powder as a comparative sample was mounted as Example 4.
[0013]
[Table 1]

[Table 2]

[0014]
Examples 1-2 are examples of ceramic charcoal. Moreover, Example 3 is an example of Bincho charcoal from Wakayama. In Example 1, many fine irregularities were formed on the surface of the molded product. In addition, micropores with meteor tails were observed. A similar state was observed on the inner surface of the hollow linear body.
[0015]
Obviously, the surface area of the molded product has increased. Similarly in Example 2, fine irregularities were formed on the surface. Although micropores were also observed, larger pores than in Example 1 were mixed, and the entire surface was felt rough. This is considered to be due to the particle size of the carbon powder. Although the same state was observed in Example 3, the state was very similar to Example 1, but there were many fine irregularities and a dull matte black.
[0016]
【The invention's effect】
As shown in the above examples and test results, the surface area of the molded product is expanded by providing continuous foaming holes and through-foaming holes such as irregularities and fine holes, and the functional effects of charcoal are more effectively exhibited. At the same time, the adhesion and scattering of charcoal powder were prevented, and it was possible to make screens and jars free from dirt.
[0017]
As an interior product, it can be expected that the charcoal has a deodorizing, deodorizing function, humidity and temperature adjustment function, air purification function such as adsorption of positive ions, etc. just by hanging it in the room.
[0018]
As a result of the compounding and the structure of the molded product that enhances the functional effect, the number of fine pores inherent to the charcoal has increased and the number of parts that directly touch the air has been increased. It was possible to greatly increase the value of.
