Description
本発明は、アルミ製芯材入り一体押出成形体および建築用部材に関する。 The present invention relates to a monolithic extruded body with an aluminum core and a building member.
建築用手摺りの製造方法として、芯材の外表面に一体押出成形によって軟質合成樹脂層および硬質合成樹脂層を形成する方法が報告されている（特許文献１）。詳しくは、走行する金属又は硬質合成樹脂よりなる芯材が、金型ダイスの内部を通過中に第１押出成形機に注入したＪＩＳＡ硬度８５以下の柔軟性を有する合成樹脂またはその合成樹脂よりなる発泡体の軟質合成樹脂層を以て被着し、その後、第２押出成形機に注入したＪＩＳＡ硬度９０以上の強靭な合成樹脂によって、前記軟質合成樹脂層の外周に厚み０．２ｍｍ以下の表皮合成樹脂層を被膜積層した後、冷却水槽で固化させ、所要寸法に切断することを特徴とした建築用手摺りの製造方法が報告されている。
しかしながら、建築用部材として用いられる成形体において、芯材として比較的安価かつ軽量な中空押出状のアルミ製のものを用いる場合、被覆合成樹脂層とアルミ製芯材との接着力が悪いという問題があった。そのような接着力が悪いと、被覆合成樹脂層とアルミ製芯材との繊膨張率の相違により、例えば建物躯体へのビス打ち部分について、被覆層樹脂が割れる等の問題が生じるのである。そのため、一体成形時に樹脂圧力によりアルミ製芯材と被覆合成樹脂とを強固に密着させなければならず、上記のような中間に柔軟層を用いることはできないうえ、一体押出成形時の圧力によりアルミ製芯材が撓んで圧縮変形することが問題となっていた。 However, in a molded article used as a building member, when a relatively inexpensive and lightweight hollow extruded aluminum product is used as the core material, the problem is that the adhesive strength between the coated synthetic resin layer and the aluminum core material is poor. was there. When such adhesive strength is poor, there is a problem that, for example, the coating layer resin breaks at a screwed portion to the building frame due to the difference in the fiber expansion rate between the coating synthetic resin layer and the aluminum core material. For this reason, the aluminum core material and the covering synthetic resin must be firmly adhered by resin pressure during integral molding, and a flexible layer cannot be used in the middle as described above. It has been a problem that the core material is bent and compressed and deformed.
本発明は、圧縮変形のないアルミ製芯材の外表面に被覆層を有してなる一体押出成形体および建築用部材を提供することを目的とする。 An object of the present invention is to provide an integrally extruded body and a building member having a coating layer on the outer surface of an aluminum core material without compression deformation.
本発明は、中空状アルミ製芯材の外表面に合成樹脂からなる被覆層を有してなり、芯材の厚みが１．０ｍｍ以上であり、芯材の厚み（Ｘ：ｍｍ）とスパン（Ｙ：ｍｍ）とが、式；
Ｙ３／Ｘ３≦５０００
の関係を満たすことを特徴とする一体押出成形体、および該一体押出成形体からなる建築用部材に関する。
The present invention has a coating layer made of a synthetic resin on the outer surface of a hollow aluminum core material, the thickness of the core material is 1.0 mm or more, the thickness of the core material (X: mm) and the span ( Y: mm) is the formula;
Y 3 / X 3 ≦ 5000
The present invention relates to a monolithic extrusion molded product that satisfies the above relationship, and a building member made of the monolithic extrusion molding.
本発明のアルミ製芯材入り一体押出成形体は、所定の芯材厚みと芯材スパンを確保するので、芯材の圧縮変形を抑制できる。特に、芯材内部に補強用仕切部材を有すると、芯材スパンを容易に確保でき、芯材の圧縮変形をより有効に抑制できる。 Since the integral extrusion molding containing an aluminum core material of the present invention secures a predetermined core material thickness and a core material span, it can suppress compression deformation of the core material. In particular, when the reinforcing partition member is provided inside the core material, the core material span can be easily secured, and the compression deformation of the core material can be more effectively suppressed.
本発明の一体押出成形体は、中空状アルミ製芯材の外表面に合成樹脂からなる被覆層を有してなるものであり、詳しくは被覆層１は、例えば、図１および図２に示すように、芯材１０の長手方向ｍだけでなく、芯材１０断面の周方向ｐにおいても継ぎ目なく連続的に形成される。図１および図２はいずれも本発明の一体押出成形体の一例を示す概略見取り図である。
The integral extruded body of the present invention has a coating layer made of a synthetic resin on the outer surface of a hollow aluminum core material. Specifically, the coating layer 1 is shown in FIGS. 1 and 2, for example. Thus, it is continuously formed not only in the longitudinal direction m of the
本明細書中、一体押出成形とは、被覆層用樹脂を押出成形すると同時に当該層を、送り込まれた芯材に順次被覆して一体化することを意味し、そのよう方法で形成されたものを一体押出成形体という。 In this specification, the integral extrusion means that the resin for the coating layer is extruded and at the same time, the layer is sequentially coated and integrated with the fed core material, and formed by such a method. Is referred to as an integral extrusion.
本発明において使用される芯材１０はアルミニウムまたはアルミニウム合金からなる中空形状を有する棒材であり、通常はアルミニウムまたはアルミニウム合金の押出成形により調製される。なお、本発明において「アルミ製」とは、「アルミニウム合金製」もその範疇に含むものである。
The
そのような芯材の厚み（肉厚）は１．０ｍｍ以上であることを要し、軽量化の観点から好ましくは１．１〜５．０ｍｍ、より好ましくは１．２〜３．０ｍｍである。芯材の厚みが１．０ｍｍ未満であると、アルミ合金の押出成形による芯材製造時、生産安定性に劣る。さらに、一体押出成形時に生じる樹脂による圧縮圧に耐えることができず、アルミ製芯材が撓んで圧縮変形される。圧縮変形された場合、被覆層の厚みが均一にならないため、例えば建築用内装材または外装材としての使用に適さない。特に、被覆層中にポリエステル系の接着層を含む場合、一体押出成形時において当該接着層の粘度が低いため、圧縮変形により接着層の厚みの均一性が失われてしまい、被覆層とアルミ製芯材との接着性が低下する。 The thickness (wall thickness) of such a core material is required to be 1.0 mm or more, and is preferably 1.1 to 5.0 mm, more preferably 1.2 to 3.0 mm from the viewpoint of weight reduction. . When the thickness of the core material is less than 1.0 mm, the production stability is inferior when the core material is manufactured by extrusion molding of an aluminum alloy. Furthermore, it cannot withstand the compression pressure caused by the resin generated during integral extrusion, and the aluminum core material is bent and compressed and deformed. When compressively deformed, the thickness of the coating layer does not become uniform, so that it is not suitable for use as, for example, an architectural interior material or exterior material. In particular, when a polyester-based adhesive layer is included in the coating layer, since the viscosity of the adhesive layer is low during integral extrusion, the uniformity of the thickness of the adhesive layer is lost due to compression deformation. Adhesiveness with the core material decreases.
芯材の断面形状は特に制限されるものではなく、例えば、略円形、略楕円形、または略方形（例えば、略長方形、略正方形）等であってよい。建築用部材の取扱い性の観点からは、略円形、略楕円形または略長方形の断面形状、特に略楕円形または略長方形の断面形状を有する芯材が好ましい。なお、芯材の断面形状とは芯材の長手方向に対して垂直な断面形状を意味するものとする。 The cross-sectional shape of the core material is not particularly limited, and may be, for example, a substantially circular shape, a substantially elliptical shape, or a substantially rectangular shape (for example, a substantially rectangular shape or a substantially square shape). From the viewpoint of handleability of the building member, a core material having a substantially circular, substantially elliptical or substantially rectangular cross-sectional shape, particularly a substantially elliptical or substantially rectangular cross-sectional shape is preferable. The cross-sectional shape of the core material means a cross-sectional shape perpendicular to the longitudinal direction of the core material.
本明細書中、略楕円形とは、例えば図１に示すように、当該断面形状における最大内径をａ（ｍｍ）、当該最大内径方向に対して垂直方向における最大内径をｂ（ｍｍ）としたとき、ｂ／ａ＜０．９５、特に０．３≦ｂ／ａ≦０．８を満たす形状をいう。断面形状における最大内径ａの実寸は本発明の目的が達成される限り特に制限されるものではなく、通常は１０〜２００ｍｍ、特に２０〜８０ｍｍが好適である。 In the present specification, for example, as shown in FIG. 1, the substantially elliptical shape is defined as a (mm) as the maximum inner diameter in the cross-sectional shape, and b (mm) as the maximum inner diameter in a direction perpendicular to the maximum inner diameter direction. In this case, the shape satisfies b / a <0.95, particularly 0.3 ≦ b / a ≦ 0.8. The actual size of the maximum inner diameter a in the cross-sectional shape is not particularly limited as long as the object of the present invention is achieved, and usually 10 to 200 mm, particularly 20 to 80 mm is preferable.
略円形とは、上記略楕円形の説明で用いた同様のａおよびｂについて、０．９５≦ｂ／ａ≦１を満たす形状をいう。 The term “substantially circular” refers to a shape satisfying 0.95 ≦ b / a ≦ 1 with respect to the same a and b used in the description of the substantially elliptical shape.
略長方形とは、例えば図２に示すように、当該断面形状における最大内径をｃ（ｍｍ）、当該最大内径方向に対して垂直方向における最大内径をｄ（ｍｍ）としたとき、ｄ／ｃ＜０．９５、特に０．１≦ｄ／ｃ≦０．８５を満たす形状をいう。断面形状における最大内径ｃの実寸は本発明の目的が達成される限り特に制限されるものではなく、通常は１０〜３００ｍｍ、特に２０〜１５０ｍｍが好適である。 For example, as shown in FIG. 2, when the maximum inner diameter in the cross-sectional shape is c (mm) and the maximum inner diameter in the direction perpendicular to the maximum inner diameter direction is d (mm), as shown in FIG. A shape satisfying 0.95, particularly 0.1 ≦ d / c ≦ 0.85. The actual size of the maximum inner diameter c in the cross-sectional shape is not particularly limited as long as the object of the present invention is achieved, and usually 10 to 300 mm, particularly 20 to 150 mm is preferable.
略正方形とは、上記略長方形の説明で用いた同様のｃおよびｄについて、０．９５≦ｄ／ｃ≦１を満たす形状をいう。 The term “substantially square” refers to a shape satisfying 0.95 ≦ d / c ≦ 1 for the same c and d used in the description of the above-described rectangle.
本発明において芯材は、中空内部に補強用仕切部材を有することが好ましい。特に芯材が略長方形または略楕円形等の断面形状を有する場合において補強用仕切部材を有することは、芯材の圧縮変形を防止する上で有効である。通常建築用部材に使用される場合は、ビス等の固定部材を使用して、建物躯体、固定用補助部材に固着されるのであるが、当該ビス打ちを考慮すると、芯材厚みを厚くすることはビス打ちを困難にするため好ましくない。また厚みを厚くすることにより、重量的にも重くなる。したがって、芯材厚みは厚くすることなく、圧縮変形を防止するために、補強用仕切部材を用いるのが好ましいのである。特に、最大内径が２０ｍｍ以上ある芯材の場合、更に言えば成形体最大外径が３０ｍｍ以上ある製品の場合、補強用仕切部材の効果が大きい。補強用仕切部材５は、例えば略長方形の断面形状を有する芯材の概略見取り図を表す図３に示すように、芯材１０の中空内部において、断面形状における最大内径の方向ｎに対して略垂直で、かつ芯材長手方向ｍに連続して形成され、芯材の内部空間を分割するものである。これによって一体押出成形時に生じる被覆樹脂による圧縮圧により芯材が撓み変形するのを有効に抑制できる。補強用仕切部材の厚みは芯材の撓み変形をより有効に抑制できる限り特に制限されず、通常は０．８〜５．０ｍｍ、好ましくは１．０〜２．０ｍｍである。補強用仕切部材は、芯材が押出成形により調製されるとき、同時に一体化形成可能である。
In the present invention, the core member preferably has a reinforcing partition member inside the hollow. In particular, in the case where the core material has a cross-sectional shape such as a substantially rectangular shape or a substantially elliptical shape, having the reinforcing partition member is effective in preventing the core material from being compressed and deformed. Usually, when used for building members, fixing members such as screws are used to fix them to the building frame and fixing auxiliary members. Is not preferable because it makes screwing difficult. Further, increasing the thickness also increases the weight. Therefore, it is preferable to use a reinforcing partition member in order to prevent compressive deformation without increasing the core material thickness. In particular, in the case of a core material having a maximum inner diameter of 20 mm or more, and more specifically, in the case of a product having a molded body maximum outer diameter of 30 mm or more, the effect of the reinforcing partition member is great. The reinforcing
芯材が有する補強用仕切部材（以下、単に仕切部材という）の数は、本発明の目的が達成される限り特に制限されるものではなく、芯材の厚み（Ｘ：ｍｍ）とスパン（Ｙ：ｍｍ）とが、式；
Ｙ３／Ｘ３≦５０００ （１）；
好ましくは
Ｙ３／Ｘ３≦２５００ （２）；
より好ましくは
Ｙ３／Ｘ３≦１５００ （３）；
の関係を満たすようなスパンを確保すればよい。Ｙ３／Ｘ３の値が大きすぎると、芯材が一体押出成形時に生じる樹脂による圧縮圧に耐えることができず、撓んで圧縮変形される。
The number of reinforcing partition members (hereinafter simply referred to as partition members) included in the core material is not particularly limited as long as the object of the present invention is achieved, and the thickness (X: mm) and span (Y : Mm) is the formula;
Y 3 / X 3 ≦ 5000 (1);
Preferably Y 3 / X 3 ≦ 2500 (2);
More preferably Y 3 / X 3 ≦ 1500 (3);
A span that satisfies this relationship may be secured. If the value of Y 3 / X 3 is too large, the core material cannot withstand the compression pressure caused by the resin generated during integral extrusion molding, and is bent and compressed and deformed.
芯材のスパンとは仕切部材によって分割された２以上の内部空間のうち、芯材断面形状における最大内径方向の寸法が最大である空間の当該寸法の値である。例えば、図３において内部空間は２つの仕切部材５によって３等分されているので、いずれの空間の最大内径方向ｎの寸法もスパン（Ｙ）に対応することを示している。図３中、Ｘは芯材の厚みを示す。
The span of the core material is a value of the dimension of the space in which the dimension in the maximum inner diameter direction in the core material cross-sectional shape is the maximum among the two or more internal spaces divided by the partition member. For example, in FIG. 3, since the internal space is divided into three equal parts by two
芯材が仕切部材を有するときの芯材スパン（Ｙ）の別の具体例を図４（Ａ）〜（Ｃ）に示す。図４（Ａ）は、略長方形の断面形状を有する芯材において内部空間が１つの仕切部材５によって２等分されているので、いずれの空間の最大内径方向の寸法もスパン（Ｙ）に対応することを示している。図４（Ｂ）は、略楕円形の断面形状を有する芯材において内部空間が１つの仕切部材５によって２等分されているので、いずれの空間の最大内径方向の寸法もスパン（Ｙ）に対応することを示している。図４（Ｃ）は、略長方形の断面形状を有する芯材において内部空間は１つの仕切部材５によって２分割されているが２等分されていないので、明らかに最大内径方向の寸法が大きい左側の空間の当該寸法がスパン（Ｙ）に対応することを示している。特に、図４（Ｃ）に示すような仕切部材を有する芯材は、断面形状の最大内径方向における中央に仕切部材を有さないので、一体押出成形体、特に建築用部材の取り付けが容易になる。
Another specific example of the core material span (Y) when the core material has a partition member is shown in FIGS. In FIG. 4A, since the inner space is divided into two equal parts by one
本発明において芯材は仕切部材を必ずしも有さなくてよい。芯材が仕切部材を有さない場合において芯材スパンは芯材の断面形状における最大内径であり、当該芯材スパンと芯材厚みとが上記「Ｙ３／Ｘ３」の関係を満たせばよい。 In the present invention, the core material does not necessarily have a partition member. When the core material does not have a partition member, the core material span is the maximum inner diameter in the cross-sectional shape of the core material, and the core material span and the core material thickness only need to satisfy the relationship of “Y 3 / X 3 ”. .
芯材が仕切部材を有さないときの芯材スパン（Ｙ）の具体例を図５（Ａ）〜（Ｂ）に示す。図５（Ａ）は、略長方形の断面形状を有する芯材が仕切部材を有さないので、断面形状における最大内径（ｃ）がスパン（Ｙ）に対応することを示している。ｃは図２においてと同様である。図５（Ｂ）は、略楕円形の断面形状を有する芯材が仕切部材を有さないので、断面形状における最大内径（ａ）がスパン（Ｙ）に対応することを示している。ａは図１においてと同様である。 Specific examples of the core material span (Y) when the core material has no partition member are shown in FIGS. FIG. 5A shows that the maximum inner diameter (c) in the cross-sectional shape corresponds to the span (Y) because the core member having a substantially rectangular cross-sectional shape does not have a partition member. c is the same as in FIG.

なお、Ｙ３／Ｘ３の値について、下限は特に限定されるものではないが、芯材の補強効果と仕切部材の必要性およびコストを考慮した場合、Ｙ３／Ｘ３≧２００であることが好ましく、特に好ましくはＹ３／Ｘ３≧４００である。 The lower limit of the value of Y 3 / X 3 is not particularly limited, but Y 3 / X 3 ≧ 200 in consideration of the reinforcing effect of the core material and the necessity and cost of the partition member. And particularly preferably Y 3 / X 3 ≧ 400.
芯材は中空内部に、一体押出成形体の取り付けのためのビスホール有してもよい。ビスホールは、芯材が押出成形により調製されるとき、同時に一体化形成可能である。 The core material may have a bis-hole for mounting the integrally extruded product in the hollow interior. The screw hole can be integrally formed at the same time when the core material is prepared by extrusion molding.
芯材の外表面に形成される被覆層１は合成樹脂からなり、いわゆる非発泡体または発泡倍率５倍以下、特に２倍以下の低発泡体の形態を有するものである。 The coating layer 1 formed on the outer surface of the core material is made of a synthetic resin and has a so-called non-foamed body or a low foamed form with a foaming ratio of 5 times or less, particularly 2 times or less.
そのような被覆層に使用される合成樹脂として、例えばポリ塩化ビニル樹脂（以後、ＰＶＣ樹脂という）、アクリロニトリル−ブタジエン−スチレン共重合樹脂（以後、ＡＢＳ樹脂という）、アクリロニトリル−スチレン−アクリルゴム共重合樹脂（以後、ＡＳＡ樹脂という）、ポリスチレン樹脂、ハイインパクトポリスチレン樹脂、アクリロニトリル−スチレン共重合樹脂（以後、ＡＳ樹脂という）、シリコン系複合ゴム変性アクリロニトリル−スチレン共重合樹脂（以後、ＳＡＳ樹脂という）、変性ポリフェニレンエーテル樹脂、ポリエチレン樹脂、ポリプロピレン樹脂、ポリメチルメタクリレート樹脂（以後、ＰＭＭＡ樹脂という）、メチルメタクリレート−ブチルアクリレート共重合樹脂、メチルメタクリレート−スチレン共重合樹脂（以後、ＭＳ樹脂という）などのアクリル系樹脂またはポリエステル系樹脂もしくはこれらの混合樹脂等が挙げられる。成形性、強靭性、経済性の面から特に好ましいのは、ＰＶＣ樹脂、ＡＢＳ樹脂、ＳＡＳ樹脂、ＡＳ樹脂、ＡＳＡ樹脂、ＰＭＭＡ樹脂であり、これらの樹脂はそれ自体、より硬質のものである。なお、これらの合成樹脂には、炭酸カルシウム、タルク、マイカ、シラスバルーン等の充填材や軽量化材、ガラス繊維やセルロース繊維等の補強材、難燃剤、その他熱安定剤、滑剤等の合成樹脂成形体に添加される各種添加剤を含むことができる。 Synthetic resins used for such coating layers include, for example, polyvinyl chloride resin (hereinafter referred to as PVC resin), acrylonitrile-butadiene-styrene copolymer resin (hereinafter referred to as ABS resin), and acrylonitrile-styrene-acrylic rubber copolymer. Resin (hereinafter referred to as ASA resin), polystyrene resin, high impact polystyrene resin, acrylonitrile-styrene copolymer resin (hereinafter referred to as AS resin), silicon-based composite rubber-modified acrylonitrile-styrene copolymer resin (hereinafter referred to as SAS resin), Modified polyphenylene ether resin, polyethylene resin, polypropylene resin, polymethyl methacrylate resin (hereinafter referred to as PMMA resin), methyl methacrylate-butyl acrylate copolymer resin, methyl methacrylate-styrene copolymer tree (Hereinafter referred to as MS resin) acrylic resin or polyester resin or a mixed resin or the like of these and the like. Particularly preferred from the viewpoints of moldability, toughness, and economy are PVC resin, ABS resin, SAS resin, AS resin, ASA resin, and PMMA resin, and these resins themselves are harder. These synthetic resins include fillers such as calcium carbonate, talc, mica, and shirasu balloons, lightweight materials, reinforcing materials such as glass fibers and cellulose fibers, flame retardants, other heat stabilizers, and synthetic resins such as lubricants. Various additives added to the molded body can be included.
被覆層は単層からなっていても、２層以上の合成樹脂層からなっていてもよいが、２層以上、特に２〜４層の合成樹脂層からなることが好ましい。被覆層が２層以上の合成樹脂層からなる場合、各層を構成する合成樹脂はそれぞれ独立して上記合成樹脂から選択されればよい。 The coating layer may be composed of a single layer or may be composed of two or more synthetic resin layers, but is preferably composed of two or more layers, particularly 2 to 4 synthetic resin layers. When the coating layer is composed of two or more synthetic resin layers, the synthetic resin constituting each layer may be independently selected from the above synthetic resins.
好ましい被覆層は２層以上の合成樹脂層からなり、芯材と接触する合成樹脂層がポリエステル系樹脂層である。ポリエステル系樹脂層の厚みは特に制限されないが、通常０．０５〜２ｍｍである。これによって、被覆層と芯材との接着性が向上するためである。特に一体成形時には、樹脂圧により芯材と密着されるため接着力が発揮される。このとき、芯材と接触するポリエステル系樹脂層以外の合成樹脂層は、ＰＶＣ樹脂、ＡＢＳ樹脂、ＳＡＳ樹脂、ＡＳ樹脂、ＡＳＡ樹脂、ＰＭＭＡ樹脂等からなっていることがより好ましい。ポリエステル系樹脂層による接着性向上効果がより有効に発揮されるためである。 A preferred coating layer is composed of two or more synthetic resin layers, and the synthetic resin layer in contact with the core material is a polyester resin layer. The thickness of the polyester resin layer is not particularly limited, but is usually 0.05 to 2 mm. This is because the adhesion between the coating layer and the core material is improved. Particularly in the case of integral molding, the adhesive force is exhibited because it is in close contact with the core material by the resin pressure. At this time, the synthetic resin layer other than the polyester-based resin layer in contact with the core material is more preferably made of PVC resin, ABS resin, SAS resin, AS resin, ASA resin, PMMA resin, or the like. This is because the effect of improving the adhesion by the polyester resin layer is more effectively exhibited.
被覆層が２層以上の合成樹脂層からなる場合、最表面層は表面を保護するための保護機能を有することが好ましい。そのような保護機能を有する最表面層は、上記合成樹脂のうち、通常ＰＭＭＡ樹脂、ＳＡＳ樹脂、ＡＳ樹脂、ＡＳＡ樹脂、ＡＢＳ樹脂、ＭＳ樹脂、ＰＶＣ樹脂からなっていることが好ましい。そのような合成樹脂の中でも、最表面層をＰＭＭＡ樹脂、ＡＢＳ樹脂、ＭＳ樹脂、ＡＳ樹脂から構成させると透明保護層とすることができる。 When the coating layer is composed of two or more synthetic resin layers, the outermost surface layer preferably has a protective function for protecting the surface. It is preferable that the outermost surface layer having such a protective function is usually made of PMMA resin, SAS resin, AS resin, ASA resin, ABS resin, MS resin, or PVC resin among the synthetic resins. Among such synthetic resins, when the outermost surface layer is made of PMMA resin, ABS resin, MS resin, or AS resin, a transparent protective layer can be obtained.
被覆層の好ましい構成を以下に示す。ただし、以下の構成に限定されるものではない。なお、最初に記載の層は芯材と接触する層であり、順に最表面層に近づく層を示し、最後に記載の層は最表面層である；
（１）ポリエステル系樹脂からなる接着層−ＰＭＭＡ樹脂からなる透明保護層；
（２）ポリエステル系樹脂からなる接着層−種剤を有する着色ＳＡＳ樹脂からなる表面加飾層；
（３）ポリエステル系樹脂からなる接着層−種剤を有する着色ＰＭＭＡ樹脂からなる加飾層−ＰＭＭＡ樹脂からなる表面層；
（４）ポリエステル系樹脂からなる接着層−着色ＡＢＳ樹脂からなる半透明保護層；
（５）ポリエステル系樹脂からなる接着層−種剤を有する着色半透明ＭＳ樹脂からなる表面加飾層；
（６）ポリエステル系樹脂からなる接着層−可飾性粉体を有する着色半透明ＰＭＭＡ樹脂からなる表面加飾層；
（７）ポリエステル系樹脂からなる接着層−可飾性粉体を有する着色ＰＭＭＡ樹脂からなる加飾層−ＰＭＭＡ樹脂からなる透明表面層；
A preferred configuration of the coating layer is shown below. However, it is not limited to the following configurations. In addition, the layer described at the beginning is a layer in contact with the core material, and shows a layer approaching the outermost surface layer in order, and the layer described at the end is the outermost surface layer;
(1) Adhesive layer made of polyester resin-transparent protective layer made of PMMA resin;
(2) Adhesive layer made of a polyester-based resin-surface decoration layer made of a colored SAS resin having a seed;
(3) Adhesive layer made of polyester-based resin-decorative layer made of colored PMMA resin having seed agent-surface layer made of PMMA resin;
(4) Adhesive layer made of polyester resin-translucent protective layer made of colored ABS resin;
(5) Adhesive layer made of a polyester-based resin-surface decoration layer made of a colored translucent MS resin having a seed;
(6) Adhesive layer made of a polyester-based resin-surface decorative layer made of a colored translucent PMMA resin having a decorative powder;
(7) Adhesive layer made of polyester-based resin-decorative layer made of colored PMMA resin having decorative powder-Transparent surface layer made of PMMA resin;
被覆層の厚みは、硬度、摩耗性、生産安定性の観点から０．３ｍｍ以上が好ましく、より好ましくは０．６ｍｍ以上である。被覆層が２層以上の合成樹脂層からなる場合、それらの合計厚みが上記範囲内であればよい。特に、被覆層厚みが０．６ｍｍ以上であれば、表面加飾層を形成する場合、安定した加飾表現が可能となる。なお、厚みの上限は特に制限されるものではないが、一体成形時の樹脂圧力が過剰になること、生産性及びコストの面より３ｍｍ以下であり、好ましくは２ｍｍ以下である。 The thickness of the coating layer is preferably 0.3 mm or more, more preferably 0.6 mm or more from the viewpoints of hardness, wearability, and production stability. When a coating layer consists of two or more synthetic resin layers, those total thickness should just be in the said range. In particular, when the coating layer thickness is 0.6 mm or more, stable decoration expression is possible when the surface decoration layer is formed. The upper limit of the thickness is not particularly limited, but is 3 mm or less, preferably 2 mm or less, in view of excessive resin pressure during integral molding, productivity and cost.
本発明の一体押出成形体は、生産性、長尺物成形、製品特性の一定性という面から、被覆層の押出成形と同時に被覆層を芯材と一体化させる、いわゆる一体押出法によって製造される。特に、２層以上の合成樹脂層からなる被覆層を有する一体押出成形体を製造する場合には、図６に示すような共押出式の一体化押出成形機によって製造される。詳しくは、各合成樹脂層を形成する樹脂を溶融・混練するための各押出機（図６中、１１，１２）より押し出された樹脂を１個のダイス１３内で積層すると同時に、当該層を、送り込まれる芯材１０に順次被覆して一体化する。一体化された後は、通常、冷却され、所望寸法に切断される。図６では２台の押出機が使用されているが、これに制限されず、被覆層を構成する合成樹脂層の数に応じて適宜設置されればよい。
The monolithic extruded product of the present invention is manufactured by a so-called monolithic extrusion method in which the coating layer is integrated with the core material simultaneously with the extrusion molding of the coating layer from the viewpoint of productivity, long product molding, and constant product characteristics. The In particular, in the case of producing an integrally extruded body having a coating layer composed of two or more synthetic resin layers, it is produced by a coextrusion type integral extruder as shown in FIG. Specifically, the resin extruded from each extruder (11, 12 in FIG. 6) for melting and kneading the resin forming each synthetic resin layer is laminated in one
本発明の一体押出成形体は、中空状アルミ製芯材の表面全面を合成樹脂にて被覆されている必要はない。例えば図３のような断面略長方形状のものであれば、上面及び下面を被覆し、側面は芯材むき出し状態であるような被覆状態であっても良い。 The integral extruded body of the present invention does not need to cover the entire surface of the hollow aluminum core material with a synthetic resin. For example, as long as the cross section has a substantially rectangular shape as shown in FIG. 3, the upper surface and the lower surface may be covered, and the side surface may be in a covered state where the core material is exposed.
