Description

本発明は、屋外等の床面上に踏板付床材等の床材を並列して敷設する際に、余白部分に巾調整材として用いられる巾調整床材に係り、特に難燃性及び強靭性、耐衝撃性等の機械的特性或は耐候性を有しかつ巾調整等のために切削加工が容易に出来る巾調整床材に関するものである。   The present invention relates to a width adjusting floor material used as a width adjusting material in a margin part when a floor material such as a floor with a tread is laid in parallel on a floor surface such as outdoors, particularly flame retardancy and toughness. The present invention relates to a width-adjustable flooring that has mechanical properties such as heat resistance and impact resistance or weather resistance and can be easily cut for width adjustment.

最近になって、例えば後述の特許文献1乃至特許文献6に示す如く、合成樹脂製フレームの上面にタイル、合成樹脂板、木質板等からなる複数の踏板を固定して構成した踏板付床材を屋外の床面に敷設して床面を構成する手段が一般的に実施されている。   Recently, for example, as shown in Patent Documents 1 to 6 to be described later, a floor material with a tread made by fixing a plurality of treads made of tiles, synthetic resin plates, wood boards, etc. on the upper surface of a synthetic resin frame. Generally, a means for constructing the floor surface by laying the door on the outdoor floor surface is implemented.

そして、前述の踏板付床材を屋外の床面に敷設した場合には、例えば図3に示す如く、床面51の全面に踏板付床材52を体裁良く敷設することが困難であるために、床面51の隅部に踏板付床材52を敷設することが出来ない余白部分53が形成されていた。   When the above-mentioned floor with flooring is laid on an outdoor floor surface, for example, as shown in FIG. 3, it is difficult to lay the flooring with flooring 52 on the entire surface of the floor 51. In the corner of the floor surface 51, a blank portion 53 where the floor material 52 with the tread plate could not be laid was formed.

従来、この余白部分53には、踏板付床材52と同一の高さを有する熱可塑性樹脂を成形した巾調整床材54がこれ等の踏板付床材52と並列して敷設されている。該巾調整床材54は余白部分53に対応して切削加工しなければならないので、このような切削加工が容易に出来る熱可塑性樹脂材で、かつ前記踏板付床材52とほぼ等しい左右巾を持って形成されていた。   Conventionally, a width-adjusting floor material 54 formed of a thermoplastic resin having the same height as the floor material 52 with a tread plate is laid in parallel with the floor material 52 with the tread plate in the margin portion 53. Since the width adjusting floor material 54 must be cut in correspondence with the blank portion 53, the width adjusting floor material 54 is a thermoplastic resin material that can be easily cut and has a width that is substantially equal to that of the floor material 52 with the tread plate. It was formed.

前述の図3に示す余白部分53に敷設される巾調整床材54は、一般的な熱可塑性樹脂を射出成形することによって構成されていた。従って、火災時を想定した設計となっていないので、屋外、ベランダ等に床材と並列して巾調整床材54を敷設した場合に、その巾調整床材54に火種が落ちた場合には、延焼を助長してしまう問題があった。   The width adjusting floor material 54 laid in the blank portion 53 shown in FIG. 3 is configured by injection molding a general thermoplastic resin. Therefore, since it is not designed for the case of fire, when the width adjustment flooring 54 is laid in parallel with the flooring outdoors, on the veranda, etc., when the fire type falls on the width adjustment flooring 54 There was a problem of promoting fire spread.

建築基準法第63条(市街地火災想定)の規定に基づく認定に係わる性能評価に於ては、床材の上面の踏板よりなる試験体(巾1,200±100、長さ2,000±200、厚み250以下)上に火種(クリブ)2個を載置し、該火種に風速3m/秒(時速10.8km)の風を吹き付けた状態で30分間放置した時、(1)延焼が試験体の端部(風下側端部、及び左右両端部)に達しないこと、(2)試験体裏面で火災を伴う延焼が観察されないこと、(3)10mm×10mm以上の貫通孔が生じないことが、認定条件となっているが、前記巾調整床材54は全て前記認定条件をクリアすることが困難である問題があった。   In performance evaluation related to accreditation based on the provisions of Article 63 of the Building Standards Law (presumed urban fires), test specimens consisting of treads on the upper surface of flooring (width 1,200 ± 100, length 2,000 ± 200) When two fire types (cribs) are placed on the thickness 250 or less) and left to stand for 30 minutes with a wind speed of 3 m / sec (10.8 km / h) on the fire type, (1) Fire spread test Do not reach the end of the body (the leeward end and the left and right ends), (2) No fire spread is observed on the back of the specimen, and (3) No through-holes of 10 mm x 10 mm or more However, although it is a certification condition, all the width adjusting floor materials 54 have a problem that it is difficult to clear the certification condition.

また、従来の巾調整床材54のように、一般的な熱可塑性樹脂を成形して構成した巾調整材は、強靭性、耐衝撃性に乏しい問題があった。従って、屋外の人が通過する床面等にこの巾調整床材54を敷設した場合には、巾調整床材54が衝撃等によって破損したり、或は巾調整床材54が長年に亘って外気にさらされて風化してもろくなる問題もあった。   In addition, the width adjusting material formed by molding a general thermoplastic resin like the conventional width adjusting floor material 54 has a problem of poor toughness and impact resistance. Therefore, when the width adjusting floor material 54 is laid on the floor surface or the like through which an outdoor person passes, the width adjusting floor material 54 is damaged by an impact or the like, or the width adjusting floor material 54 is used for many years. There was also the problem of being brittle when exposed to the open air.

本発明に係る巾調整床材は、前述の従来の多くの問題点に鑑み開発された全く新しい技術であって、特に上表面に火種が落ちた場合にも、延焼を防止することが出来、かつ強靭性、耐衝撃性等の機械的特性或は耐候性を有し、さらに切削加工が容易な巾調整床材の技術を提供するものである。   The width-adjusting floor material according to the present invention is a completely new technology developed in view of the above-described many problems of the prior art, and can prevent the spread of fire even when a fire type falls on the upper surface, In addition, the present invention provides a technique of a width-adjusting floor material that has mechanical properties such as toughness and impact resistance or weather resistance, and is easy to cut.

本発明の目的を達成するための本発明に係る巾調整床材の第1の構成は、屋外の床面に踏板付床材等を敷設する際に用いられる巾調整用の調整床材であって、自己消化性熱可塑性樹脂で成形されていることを特徴とした巾調整床材である。   The first configuration of the width adjusting floor material according to the present invention for achieving the object of the present invention is an adjusting floor material for width adjustment used when laying a floor material with a tread on an outdoor floor surface. The floor-adjusting floor material is characterized by being molded with a self-digesting thermoplastic resin.

また、本発明に係る巾調整床材の第2の構成は、前記自己消化性熱可塑性樹脂がポリアミド66、ポリアミド6、ポリトリメチレンテレフタレート、ポリブチレンテレフタレート内の少なくとも一つを主原料とする熱可塑性樹脂組成物であることを特徴とする第1構成の巾調整床材である。   A second configuration of the width-adjusting floor material according to the present invention is a heat source in which the self-digestible thermoplastic resin is at least one of polyamide 66, polyamide 6, polytrimethylene terephthalate, and polybutylene terephthalate as a main raw material. It is a width-adjusted flooring material having a first configuration, which is a plastic resin composition.

また、本発明に係る巾調整床材の第3の構成は、前記自己消化性熱可塑性樹脂が木粉を30〜85重量%を含む熱可塑性樹脂組成物であることを特徴とする第1構成或は第2構成の巾調整床材である。   Moreover, the 3rd structure of the width adjustment floor material which concerns on this invention is a thermoplastic resin composition in which the said self-digestible thermoplastic resin contains 30-85 weight% of wood flour, The 1st structure characterized by the above-mentioned. Or it is the width | variety adjustment floor material of a 2nd structure.

また、本発明に係る巾調整床材の第4の構成は、前記熱可塑性樹脂で成形された巾調整床材の比重が1.0以上であることを特徴とした第1構成乃至第3構成の巾調整床材である。   Moreover, the 4th structure of the width adjustment floor material which concerns on this invention is that the specific gravity of the width adjustment floor material shape | molded with the said thermoplastic resin is 1.0 or more, The 1st structure thru | or 3rd structure characterized by the above-mentioned. This is a width-adjustable flooring.

また、本発明に係る巾調整床材の第5の構成は、前記巾調整床材は敷設される床面の形状に合わせて容易に切削加工が可能であることを特徴とした第1構成乃至第4構成の巾調整床材である。   According to a fifth configuration of the width-adjusting floor material according to the present invention, the width-adjusted floor material can be easily cut according to the shape of the floor surface to be laid. It is a width adjusting floor material of the 4th composition.

本発明に係る巾調整床材の第1構成は、自己消化性熱可塑性樹脂で成形されているので、床材全体が難燃性(自己消化性)を有しており、火災時に火種が床面に点火された場合にも、床材が延焼することを防止出来る。   Since the first configuration of the width adjusting floor material according to the present invention is formed of a self-digestible thermoplastic resin, the entire floor material has flame retardancy (self-digestibility), and the fire type is the floor during a fire. Even when the surface is ignited, it is possible to prevent the floor material from spreading.

本発明に使用される自己消化性熱可塑性樹脂は、炎に接しているうちは燃えるが、炎を取り除くと自然に消化する性質を有している。具体的にはJIS K6911−1995「熱硬化性プラスチック一般試験方法」の耐燃性A法で定義されるものである。一般的に燃焼距離(mm単位)で耐火性を表し、燃焼距離が25mm以下の場合は不燃性、25mmを超え100mm以下の場合を自己消化性と呼ばれている。   The self-digestible thermoplastic resin used in the present invention has the property of burning while in contact with the flame, but naturally digesting when the flame is removed. Specifically, it is defined by the flame resistance A method of JIS K6911-1995 “General Test Method for Thermosetting Plastics”. In general, fire resistance is expressed in terms of the combustion distance (in mm). When the combustion distance is 25 mm or less, it is called nonflammability, and when it exceeds 25 mm and 100 mm or less, it is called self-digestibility.

また、本発明に係る巾調整床材の第2の構成は、自己消化性熱可塑性樹脂がポリアミド66、ポリアミド6、ポリトリメチレンテレフタレート、ポリブチレンテレフタレートの内の少なくとも一つを主原料とする熱可塑性樹脂組成物が用いられて成形されているので、床材全体が難燃性を有しており、火災時にも床材が延焼することを防止出来る。   The second configuration of the width-adjusting floor material according to the present invention is a heat source in which the self-digestible thermoplastic resin is mainly at least one of polyamide 66, polyamide 6, polytrimethylene terephthalate, and polybutylene terephthalate. Since the plastic resin composition is used and molded, the entire flooring material is flame retardant, and it is possible to prevent the flooring from spreading even in the event of a fire.

また、第2の構成に於ては、ポリアミド66、ポリアミド6、ポリトリメチレンテレフタレート、ポリブチレンテレフタレート等のエンジニアリングプラスチックを使用して巾調整床材を成形するので、構成された巾調整床材は、強靭性、耐衝撃性等の機械的特性と耐候性を有している。従って、常に外気にさらされ、かつ人が通過する屋外の床面に有効に敷設することが出来る。   In the second configuration, the width adjusting floor material is molded using engineering plastics such as polyamide 66, polyamide 6, polytrimethylene terephthalate, polybutylene terephthalate, etc. It has mechanical properties such as toughness and impact resistance and weather resistance. Therefore, it can be effectively laid on the outdoor floor surface that is always exposed to the outside air and through which people pass.

本発明に係る巾調整床材の第3の構成は、自己消化性熱可塑性樹脂が木粉を30〜85重量%を含有しているので、木粉の隙間に熱可塑性樹脂が入り込んで稠密な組織を構成することが出来、これによって、床材全体が難燃性を保持することが出来る。   In the third configuration of the width adjusting floor material according to the present invention, since the self-digestible thermoplastic resin contains 30 to 85% by weight of wood flour, the thermoplastic resin enters the gap between the wood flour and is dense. An organization can be constituted, and the whole flooring material can hold incombustibility by this.

さらに、本発明の巾調整床材の第3構成に於ては、前述のようなポリアミド66、ポリアミド6等の特殊な自己消化性熱可塑性樹脂を使用しなくとも、一般的な熱可塑性樹脂に木粉を所定の割合で混入して組成物を構成出来るので、巾調整床材を安価に製造することが出来る。   Furthermore, in the third configuration of the width adjusting floor material of the present invention, a general thermoplastic resin can be used without using a special self-digesting thermoplastic resin such as polyamide 66 or polyamide 6 as described above. Since the composition can be constituted by mixing wood powder at a predetermined ratio, the width-adjusted flooring can be manufactured at a low cost.

本発明の巾調整床材の第4構成に於ては、巾調整床材をポリアミド66、ポリアミド6等の特殊な自己消化性熱可塑性樹脂を使用して成形するか、或は熱可塑性樹脂の中に所定の割合で木粉を混入した組成物で巾調整床材を成形した場合には、いずれの場合にも巾調整床材の比重を1.0以上にすることが出来る。   In the fourth configuration of the width-adjusting floor material of the present invention, the width-adjusting floor material is molded using a special self-digesting thermoplastic resin such as polyamide 66, polyamide 6 or the like. When the width-adjusted flooring material is molded with a composition in which wood powder is mixed at a predetermined ratio, the specific gravity of the width-adjustable flooring material can be 1.0 or more in any case.

従って、巾調整床材を重く丈夫に形成することが出来る。かつ踏板付床材を並列した余白部分に、所定の寸法に加工された巾調整床材を埋め込んだ場合にも、台風時等で屋上等に雨水が溜まっても、巾調整床材が浮き上って移動することがない。また、本発明の巾調整床材は、所定の寸法に加工することによって、雨水を流す溝のフーチング材としても利用することが出来る。   Therefore, the width adjusting floor material can be formed heavy and strong. In addition, even when the width adjustment floor material processed to the specified dimensions is embedded in the margin part where the floor material with treads is juxtaposed, the width adjustment floor material will float even if rainwater accumulates on the rooftop etc. due to typhoons etc. I will not move. Moreover, the width adjusting floor material of the present invention can be used as a footing material for a groove through which rainwater flows by processing into a predetermined dimension.

本発明の巾調整床材の第5構成に於ては、敷設される床面の形状に合わせて容易に切削加工が可能であるので、屋外、ベランダ等の床面に踏板付床材を敷設した際に生じた余白部分に所定の寸法に切断された巾調整床材を体裁良く埋設することが出来る。   In the fifth configuration of the width adjusting floor material of the present invention, it is possible to easily cut in accordance with the shape of the floor surface to be laid. The width-adjusted flooring material cut into a predetermined size can be embedded with good appearance in the blank space generated at the time.

図により本発明に係る巾調整床材の一実施例の構成について詳述すると、図1は本発明に係る巾調整床材の表側の斜視図、図2は図1の巾調整床材の裏側の斜視図である。   The configuration of an embodiment of the width adjusting floor material according to the present invention will be described in detail with reference to the drawings. FIG. 1 is a front perspective view of the width adjusting floor material according to the present invention, and FIG. 2 is the back side of the width adjusting floor material of FIG. FIG.

図1及び図2に於て、1は本発明に係る巾調整床材であって、後述の自己消化性熱可塑性樹脂を用いて射出成形法で一体成形されている。この巾調整床材1は、所定の厚みを有する表板2の裏面に多数の円筒状脚3が所定の巾隔を保って、突設されることによって構成されている。   1 and 2, reference numeral 1 denotes a width-adjusting floor material according to the present invention, which is integrally formed by an injection molding method using a self-digestible thermoplastic resin described later. The width-adjusting flooring 1 is configured by projecting a large number of cylindrical legs 3 on a back surface of a front plate 2 having a predetermined thickness while maintaining a predetermined width.

また、表板2の全面には多数の***4が上下方向に貫通されている。巾調整床材1の高さは、図3に例示した踏板付床材52の高さと等しく形成されており、図3に示す余白部分53に巾調整床材1を敷設した場合には、踏板付床材52と巾調整床材1の上面とが夫々面一になるように構成されている。   A large number of small holes 4 are penetrated in the vertical direction on the entire surface of the front plate 2. The height of the width-adjusting flooring 1 is formed to be equal to the height of the flooring 52 with the tread illustrated in FIG. 3, and when the width-adjusting flooring 1 is laid in the margin portion 53 shown in FIG. The attached flooring 52 and the upper surface of the width adjusting flooring 1 are configured to be flush with each other.

前記巾調整床材1を成形するに当っては、自己消化性熱可塑性樹脂であるポリアミド66、ポリアミド6、ポリトリメチレンテレフタレート、ポリブチレンテレフタレート内の少なくとも一つを主原料として射出成形法を用いて成形することが出来る。   In forming the width-adjusting flooring 1, an injection molding method is used with at least one of polyamide 66, polyamide 6, polytrimethylene terephthalate, and polybutylene terephthalate, which are self-digestible thermoplastic resins, as a main raw material. Can be molded.

さらに、前述のポリアミド66等の自己消化性熱可塑性樹脂を使用しないで、ポリプロピレン等の熱可塑性樹脂の中に木粉を混入した木質組成物を用いて難燃性(自己消化性)に富む巾調整床材1を成形することも出来る。この実施例の場合には、高価なポリアミド66等の自己消化性熱可塑性樹脂を使用しないので、巾調整床材1を安価に製造することが出来る。   Furthermore, a width rich in flame retardancy (self-digestibility) using a woody composition in which wood flour is mixed in a thermoplastic resin such as polypropylene without using the above-mentioned self-digestible thermoplastic resin such as polyamide 66. The adjusted flooring 1 can also be formed. In the case of this embodiment, since the expensive self-digesting thermoplastic resin such as polyamide 66 is not used, the width adjusting flooring 1 can be manufactured at low cost.

本発明者等が長年に亘って実験した結果、熱可塑性樹脂に対する木粉の比重(重量%)を変化させた場合には、後述の〔表1〕に示すような結果が得られた。   As a result of experiments conducted by the present inventors for many years, when the specific gravity (% by weight) of the wood flour with respect to the thermoplastic resin was changed, the results shown in [Table 1] described later were obtained.

Figure 2006257750
Figure 2006257750

〔表1〕で明らかなように、実施例1乃至5に示す如く、熱可塑性樹脂に対する木粉の比率(重量%)を30%以上にして巾調整床材1を成形した場合には、巾調整床材1自体自己消化性能(難燃性)を有し、かつ強靭性、耐衝撃性等の機械的特性、或は耐候性を有していることが判明した。   As apparent from Table 1, when the width-adjusted flooring 1 was molded with the ratio (% by weight) of the wood flour to the thermoplastic resin being 30% or more as shown in Examples 1 to 5, the width It was found that the adjusted flooring 1 itself has self-extinguishing performance (flame retardancy) and has mechanical properties such as toughness and impact resistance, or weather resistance.

しかし、〔表1〕の比較例1、2、3に示す如く、熱可塑性樹脂に対する木粉の比率(重量%)を25%以下にして巾調整床材1を成形した場合には、巾調整床材1の自己消火性能が低下し、かつ強靭性、耐衝撃性等の機械的特性、或は耐候性も低下していることが判明した。   However, as shown in Comparative Examples 1, 2, and 3 in [Table 1], when the width-adjusted flooring 1 is formed with the ratio (weight%) of the wood flour to the thermoplastic resin being 25% or less, the width adjustment is performed. It was found that the self-extinguishing performance of the flooring 1 was lowered, and mechanical properties such as toughness and impact resistance, or weather resistance were also lowered.

また、熱可塑性樹脂に対する木粉の比率(重量%)を90%以上にした場合には、射出成形による巾調整床材1の成形が不可能となり、かつ無理に成形した場合には、吸水性が極めて高い巾調整床材1となり、屋外での使用に耐えられなくなることが判明した。   In addition, when the ratio (% by weight) of the wood powder to the thermoplastic resin is 90% or more, it becomes impossible to form the width-adjusted flooring material 1 by injection molding. Has become an extremely high width-adjusting flooring 1 and cannot be used outdoors.

前記実施例の如く、巾調整床材1をポリアミド66、ポリアミド6、ポリトリメチレンテレフタレート、ポリブチレンテレフタレート等の特殊な自己消化性熱可塑性樹脂を使用して成形した場合、或は熱可塑性樹脂の中に木粉を所定の割合で混入した組成物で成形した場合には、いずれの場合にも、巾調整床材1の比重を1.0以上にすることが出来る。     When the width adjusting flooring 1 is molded using a special self-digesting thermoplastic resin such as polyamide 66, polyamide 6, polytrimethylene terephthalate, polybutylene terephthalate, etc. When it shape | molds with the composition which mixed the wood powder in the predetermined ratio, the specific gravity of the width adjustment flooring 1 can be 1.0 or more in any case.

特に、熱可塑性樹脂の中に木粉を所定の割合で混入した組成物で巾調整床材1を成形した場合には、木粉の隙間に熱可塑性樹脂が入り込んで稠密な組織を構成するので、巾調整床材1の全体の比重が大きくなることが明らかとなった。従って、このように比重の大きく巾調整床材1を前記余白部分53に敷設した場合には、この余白部分53に水が溜まった場合にも、巾調整床材1が浮き上って流される心配がない。   In particular, when the width-adjusted flooring 1 is formed with a composition in which wood powder is mixed in a thermoplastic resin at a predetermined ratio, the thermoplastic resin enters a gap between the wood powders to form a dense structure. It became clear that the specific gravity of the entire width-adjusted flooring 1 was increased. Accordingly, when the width adjusting flooring 1 having a large specific gravity is laid on the blank portion 53 as described above, the width adjusting floor material 1 floats and flows even when water accumulates in the blank portion 53. There is no worry.

さらに、前述の本発明に係る巾調整床材1の表板2には***4が上下方向に貫通されているので、敷設床面に雨水が多量に降った場合にも、***4で雨水を屋上等の床面に流通させることが出来る。さらに、床面等に吹き付ける風もこの***4を通して流通させることが出来る。   Furthermore, since the small holes 4 are vertically penetrated in the front plate 2 of the width adjusting floor material 1 according to the present invention described above, even if a large amount of rainwater falls on the laying floor surface, It can be distributed on the floor such as the rooftop. Further, the wind blown on the floor surface or the like can be circulated through the small holes 4.

本発明に係る巾調整床材1は、ポリアミド66等の自己消化性熱可塑性樹脂或は木粉が所定の割合で混入されたポリプロピレン等の熱可塑性樹脂等を用いて成形されているので、巾調整床材1は図3に示すような余白部分53に合わせて簡単切断加工することが出来る。従って、余白部分53を巾調整床材1で体裁良く埋設することが出来る。   The width-adjusting flooring 1 according to the present invention is formed using a self-digesting thermoplastic resin such as polyamide 66 or a thermoplastic resin such as polypropylene mixed with wood powder at a predetermined ratio. The adjusting floor material 1 can be easily cut and processed in accordance with a margin portion 53 as shown in FIG. Therefore, the blank portion 53 can be embedded with good appearance by the width adjusting floor material 1.

本発明の巾調整床材1は、上面には意匠面を有し、また下部には排水の為の円筒状脚3を有する為、複雑な形状をしている。故に射出成形での成形が一般的であり、故に使用される自己消火性樹脂は射出成形可能な程度の成形性を有しているもので無ければならない。   The width adjusting floor material 1 of the present invention has a complicated shape because it has a design surface on the upper surface and a cylindrical leg 3 for drainage on the lower portion. Therefore, injection molding is generally used. Therefore, the self-extinguishing resin to be used must have a moldability that allows injection molding.

また、本発明で使用される自己消火性樹脂には、床材として要求される機械的物性、特に強靭性や耐衝撃性が良好なものでなくてはならない。また更には本発明の巾調整材は主に屋外で使用されるので、耐候性が良好な自己消火性樹脂を選択しなくてはならない。   In addition, the self-extinguishing resin used in the present invention must have good mechanical properties required for flooring, particularly toughness and impact resistance. Furthermore, since the width adjusting material of the present invention is mainly used outdoors, a self-extinguishing resin having good weather resistance must be selected.

自己消火性樹脂としては、ポリスチレンの難燃グレード、ABS樹脂の難燃グレード、ポリカーボネート樹脂の難燃グレード、ポリトリメチレンテレフタレートの難燃グレード、ポリブチレンテレフタレートの難燃グレード、ポリアミド66、ポリアミド6等が知られているが、前記の各要求特性から判断すると、本発明で使用できる自己消火性樹脂は、ポリトリメチレンテレフタレートの難燃グレード、ポリブチレンテレフタレートの難燃グレード、ポリアミド66、ポリアミド6が好適である。   Self-extinguishing resin includes flame retardant grade of polystyrene, flame retardant grade of ABS resin, flame retardant grade of polycarbonate resin, flame retardant grade of polytrimethylene terephthalate, flame retardant grade of polybutylene terephthalate, polyamide 66, polyamide 6 etc. However, judging from the above-mentioned required characteristics, the self-extinguishing resin that can be used in the present invention is a flame retardant grade of polytrimethylene terephthalate, a flame retardant grade of polybutylene terephthalate, polyamide 66, and polyamide 6 Is preferred.

更に言えば、難燃剤を配合しなくても自己消化性を発現できるポリアミド66、ポリアミド6が、より成形がしやすく機械的物性も難燃剤の配合に左右されないことから、更に好適である。   Furthermore, polyamide 66 and polyamide 6 that can exhibit self-digestibility without blending a flame retardant are more preferable because they are easier to mold and the mechanical properties are not affected by the blend of the flame retardant.
