Description
【発明の詳細な説明】 リサイクル製品材料の製造方法 本発明は、リサイクル製品材料において所定の引張率間隔内で所定の強度に達 するために、少なくとも1種のマトリックス材料と少なくとも1種の繊維材料と からなるリサイクル製品材料の製造方法に関する。 最近、環境面やエネルギーの経済的利用法などに関して望ましいリサイクルの ために回収可能なプラスチックの処理が優先課題となってきている。回収したフ ィルムを粒状にして製造する目的で農業及び工業において包装フィルムを収集す ることを開始している成功例もある。 例えば、国際特許出願公開93/25609号公報及び国際特許出願公開94 /09959号公報は、この分野においてすでに知られている。これらの公報で は、回収プラスチック及び繊維材の再利用のための方法及び装置を述べている。 この従来技術の課題は、回収されたプラスチックの汚染の程度と、メルトイン デックスを含む多数の異種プラスチックの存在であり、その結果として、製造さ れた製品材料は所定の強度に達しない。また、粒状化するノズル及び瀘過機器が 詰まりやすくなり、非常に均質でない最終生成物となる課題がある。 上述の従来公報においては、この強度の問題に対するいかなる解決法も示して いなかった。 本発明の目的は、リサイクル製品材料の早期製造に伴う前記欠陥要因の影響の 除去あるいは減少を目的として、前記リサイクル製品材料に所定の引張率間隔に 対して所定の強度を達成することである。このためには、リサイクル製品材料中 に可能な限り大きい内部の微小応力を生じさせる必要がある。これは、リサイク ル製品材料の異なる容積成分におけるマトリックス材料と繊維材料とが、それら の弾性係数、剪断係数及びポアソン比の値が断続的な分布で得られ、そしてリサ イクル製品材料の繊維のサイズを規定する表示曲線の連続的分布を対称とする本 発明により達成される。 本発明の他の特別な特徴によれば、繊維材料/混合繊維材料の繊維径に対する 繊維長の割合が分散することであり、これにより、繊維の大半がその不均質な孤 立部分が互いに架橋可能であり、さもなければその繊維間に不完全な接着力を発 生する。 本発明のさらに顕著な特徴は、前記分布は好適には非常に広範なためマトリッ クス材料/繊維材料の1又はそれ以上が汚染されてもリサイクル製品材料の強度 上好ましくない影響を生じない。 本発明のさらなる特徴によれば、前記繊維材料のそれぞれの構成要素が汚染物 の粒子サイズを超えるものであり、すなわち、マトリックス材料/繊維材料の1 又はそれ以上が汚染されても、リサイクル製品材料の強度に対して好ましくない 影響を生じない。 本発明のさらなる利点は、以下の記述により明らかであり、図1に描写されて いるのは、本発明による方法における表示曲線の例である。図2は、リサイクル 製品材料中の種々の容積成分を示す。 本発明の方法によるリサイクル製品材料の製造は、当業者には周知の従来型の 装置を用いて、マトリックス材料及び繊維材料の弾性係数及び剪断係数の値から 算出されるポアソン比を検査するための測定装置を補充的に使用する。万一、前 述した本発明の多数の特徴の断続的な分布が得られないときには、手動修正ある いは自動修正が行われ、断続的な分布を達成しなかった材料は、前の工程に戻さ れ、つまり、その材料はもう一度前の工程を通過する。 図1は、リサイクル製品材料の繊維サイズを規定する表示曲線の一例を示す。 この表示曲線において、塊/粒は最大4mmの径を有する。ここで、繊維の大半は 曲線に従った分散で約2mmの長さで選択されている。 図2は、本発明に従った方法により製造されたリサイクル製品材料1の例を示 す。塊/粒は、繊維の配列が好適に異なる1a1,1a2・・・のN個の容積成分 として結合されており、これには種々の容積成分が包含される。この結果の意味 するところは、本発明により、容積成分夫々における弾性係数(Eij)、剪断係 数(Gij)及びポアソン比(υij)の値は、隣接する容積成分における同様の容 積成分の値とは異なり、このことが一対の大きな内部応力をもたらす。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for producing a recycled product material in which at least one matrix material and at least one fiber material are used to achieve a predetermined strength within a predetermined tensile rate interval in the recycled product material. And a method for producing a recycled product material comprising: Recently, the treatment of recoverable plastics for desirable recycling has become a priority, for example, in terms of environmental aspects and economical use of energy. Some successful cases have begun collecting packaging films in agriculture and industry for the purpose of granulating and manufacturing the recovered films. For example, WO 93/25609 and WO 94/09959 are already known in the art. These publications describe a method and apparatus for recycling recycled plastics and fibrous materials. The problem of this prior art is the degree of contamination of the recovered plastic and the presence of a large number of different plastics, including the melt index, so that the manufactured product material does not reach a certain strength. Also, there is a problem that the nozzles for granulation and the filtration equipment tend to be clogged, resulting in a very inhomogeneous end product. The above-mentioned prior publications do not provide any solution to this strength problem. An object of the present invention is to achieve a predetermined strength for a predetermined tensile rate interval in the recycled product material for the purpose of eliminating or reducing the influence of the defect factor accompanying the early production of the recycled product material. For this purpose, it is necessary to generate as large an internal small stress as possible in the recycled product material. This means that the matrix material and the fiber material in the different volume components of the recycled product material have their modulus of elasticity, shear modulus and Poisson's ratio values obtained in an intermittent distribution, and define the fiber size of the recycled product material. This is achieved by the present invention, which makes the continuous distribution of the indicated display curves symmetric. According to another special feature of the invention, the ratio of the fiber length to the fiber diameter of the fibrous material / mixed fibrous material is dispersed, so that the majority of the fibers are capable of cross-linking their heterogeneous isolated parts with each other. Otherwise an incomplete adhesion between the fibers will occur. A further salient feature of the invention is that the distribution is preferably so extensive that contamination of one or more of the matrix materials / fiber materials does not have an unfavorable effect on the strength of the recycled product material. According to a further feature of the invention, each component of the fibrous material is above the particle size of the contaminant, i.e., even if one or more of the matrix material / fibrous material is contaminated, the recycled product material No undesirable effect on the strength of the steel. Further advantages of the present invention are apparent from the following description, depicted in FIG. 1 is an example of a display curve in a method according to the present invention. FIG. 2 shows the various volume components in the recycled product material. The production of recycled product materials according to the method of the present invention uses conventional equipment well known to those skilled in the art to check the Poisson's ratio calculated from the values of the modulus and shear modulus of the matrix and fiber materials. Use the measuring device supplementarily. Should the intermittent distribution of many of the features of the invention described above not be obtained, manual or automatic corrections will be made and the material that does not achieve the intermittent distribution will be returned to the previous step, That is, the material goes through the previous step once again. FIG. 1 shows an example of a display curve defining a fiber size of a recycled product material. In this display curve, the chunk / grain has a maximum diameter of 4 mm. Here, the majority of the fibers are selected with a dispersion according to the curve and a length of about 2 mm. FIG. 2 shows an example of a recycled product material 1 produced by the method according to the invention. The agglomerates / granules are combined as N volume components 1a1, 1a2... In which the arrangement of the fibers is preferably different, including various volume components. The implication of this result is that, according to the present invention, the values of the elastic modulus (E ij ), shear modulus (G ij ) and Poisson's ratio (υ ij ) in each of the volume components will be the same for the adjacent volume components. Unlike the value, this results in a pair of large internal stresses.
