It has a three-layer structure.

樹脂フィルム２３は、ポリプロピレン（ＰＰ）のフィルムであって、厚さが約２０μｍになっている。なお、樹脂フィルム２３の片面又は両面には、接着強度を向上させるために、コロナ処理が施されている。   The resin film 23 is a polypropylene (PP) film and has a thickness of about 20 μm. In addition, in order to improve adhesive strength, the corona treatment is given to the single side | surface or both surfaces of the resin film 23. FIG.

着色樹脂層２２は、ポリプロピレン樹脂（ＰＰ）に着色剤を添加してなる着色樹脂により構成され、着色樹脂層２２の色は、添加する着色剤を変更することで自在に変更可能となっている。また、着色樹脂層２２の厚みは５〜６０μｍになっている。   The colored resin layer 22 is made of a colored resin obtained by adding a colorant to polypropylene resin (PP), and the color of the colored resin layer 22 can be freely changed by changing the colorant to be added. . Moreover, the thickness of the colored resin layer 22 is 5 to 60 μm.

スパンレース不織布２１は、例えば、ＰＥＴ製、ポリブチレンテレフタレート（ＰＢＴ）製であって、白色になっている。また、スパンレース不織布２１の面密度（目付量）は、１０〜８０ｇ／ｍ２になっている。 The spunlace nonwoven fabric 21 is made of, for example, PET or polybutylene terephthalate (PBT), and is white. Moreover, the surface density (weight per unit area) of the spunlace nonwoven fabric 21 is 10 to 80 g / m 2 .

ここで、スパンレース不織布２１には、押出ラミネートの際に、着色樹脂の一部が含浸していて、積層シート２０をスパンレース不織布２１側から見ると、全体が着色樹脂の色に見えるようになっている。また、着色樹脂の含浸によって、スパンレース不織布２１の表面の外観変化がＢ級以上（ＪＩＳ Ｌ１０９６ Ｃ法において摩耗輪ＣＳ−１０、荷重２．４５Ｎ、摩擦回数５０回としたとき）となっている。   Here, the spunlace nonwoven fabric 21 is impregnated with a part of the colored resin at the time of extrusion lamination, and when the laminated sheet 20 is viewed from the spunlace nonwoven fabric 21 side, the whole looks like the color of the colored resin. It has become. Moreover, the appearance change of the surface of the spunlace nonwoven fabric 21 is grade B or more (when the wear wheel CS-10, the load is 2.45 N, the number of friction is 50 times in the JIS L1096 C method) due to the impregnation of the colored resin. .

次に、車両用天井内装材１０の製造方法について説明する。車両用天井内装材１０を製造するには、図４に示した熱プレス成形型３０を用いる。この熱プレス成形型３０は、上型３１と下型３２とで構成され、各型３１，３２には、車両用天井内装材１０の形状に応じた成形面が形成されている。   Next, the manufacturing method of the ceiling interior material 10 for vehicles is demonstrated. In order to manufacture the vehicular ceiling interior material 10, the hot press mold 30 shown in FIG. 4 is used. The hot press mold 30 includes an upper mold 31 and a lower mold 32, and each mold 31, 32 has a molding surface corresponding to the shape of the vehicle ceiling interior material 10.

熱プレス成形型３０にて車両用天井内装材１０をするには、まず、板状のウレタン発泡体１１の両面に、イソシアネート系化合物を含む熱硬化型接着材４１を塗布し、ウレタン発泡体１１の表側に積層シート２０、裏側に裏面材１８を重ねて、熱プレス成形型３０にセットする（図４参照）。なお、熱硬化型接着材４１を塗布するとき、ガラス繊維マット４２をウレタン発泡体１１に重ねて、熱硬化型接着材４１の塗布層にガラス繊維マット４２が含まれるようにしておく。   In order to make the vehicular ceiling interior material 10 with the hot press mold 30, first, a thermosetting adhesive 41 containing an isocyanate compound is applied to both surfaces of the plate-like urethane foam 11, and the urethane foam 11. The laminated sheet 20 is stacked on the front side and the back material 18 is stacked on the back side and set in the hot press mold 30 (see FIG. 4). When the thermosetting adhesive 41 is applied, the glass fiber mat 42 is stacked on the urethane foam 11 so that the glass fiber mat 42 is included in the coating layer of the thermosetting adhesive 41.

次いで、熱プレス成形型３０にて、裏面材１８、ウレタン発泡体１１及び積層シート２０を一体に熱プレス成形する。このとき、熱プレス成形型３０の加熱により、熱硬化型接着材４１が硬化して接着層１５が形成され、この接着層１５によって、ウレタン発泡体１１の表側に積層シート２０が、ウレタン発泡体１１の裏側に裏面材１８が接着される（図１参照）。また、ガラス繊維マット４２は、接着層１５と一体となったガラス繊維層１６となる。そして、プレス成形品を熱プレス成形型３０から取り外すことで、車両用天井内装材１０が得られる。   Next, the back material 18, the urethane foam 11, and the laminated sheet 20 are integrally hot press molded with a hot press mold 30. At this time, the thermosetting adhesive 41 is cured by the heating of the hot press mold 30 to form the adhesive layer 15, and the adhesive sheet 15 forms the laminated sheet 20 on the front side of the urethane foam 11. The back surface material 18 is bonded to the back side of 11 (see FIG. 1). Further, the glass fiber mat 42 becomes the glass fiber layer 16 integrated with the adhesive layer 15. And the ceiling interior material 10 for vehicles is obtained by removing the press-molded product from the hot press mold 30.

なお、本実施形態では、上述のように、スパンレース不織布２１に着色樹脂の一部が含浸しているので、車両用天井内装材１０に深絞り部分が有る場合であっても、スパンレース不織布２１が剥がることが防がれる。   In the present embodiment, since the spunlace nonwoven fabric 21 is impregnated with a part of the colored resin as described above, even if the vehicular ceiling interior material 10 has a deep drawn portion, the spunlace nonwoven fabric is used. 21 is prevented from peeling off.

次に、車両用天井内装材１０の作用効果について説明する。本実施形態の車両用天井内装材１０は、スパンレース不織布２１の裏側に着色樹脂層２２を有した構造になっているので、スパンレース不織布２１の目付量を小さくしても、車両用天井内装材１０の内部が透けて見えることが防がれ、外観不良を防ぐことができる。また、車両用天井内装材１０では、スパンレース不織布２１と樹脂フィルム２３を着色樹脂で押出ラミネートしてなる積層シート２０が用いられているので、白色のスパンレース不織布２１に着色樹脂を含浸させて、車両用天井内装材の１０スパンレース不織布２１側全体を着色樹脂の色に見せることができる。従って、着色樹脂の色を変更することで、車両用天井内装材の表側の色を自在に変更することが可能になる。しかも、本実施形態では、スパンレース不織布２１の表面の外観変化がＢ級以上（ＪＩＳ Ｌ１０９６ Ｃ法において摩耗輪ＣＳ−１０、荷重２．４５Ｎ、摩擦回数５０回としたとき）となるように、着色樹脂がスパンレース不織布２１に含浸しているので、スパンレース不織布２１の表面のほつれを抑えることができる。   Next, the effect of the vehicle ceiling interior material 10 will be described. Since the vehicular ceiling interior material 10 of the present embodiment has a structure having the colored resin layer 22 on the back side of the spunlace nonwoven fabric 21, even if the basis weight of the spunlace nonwoven fabric 21 is reduced, the vehicular ceiling interior material 10 is provided. It is possible to prevent the inside of the material 10 from being seen through, and to prevent poor appearance. Moreover, since the laminated sheet 20 formed by extrusion laminating the spunlace nonwoven fabric 21 and the resin film 23 with a colored resin is used in the vehicle interior ceiling material 10, the white spunlace nonwoven fabric 21 is impregnated with the colored resin. The entire 10-spun lace nonwoven fabric 21 side of the vehicle interior interior material can be shown in the color of the colored resin. Therefore, by changing the color of the colored resin, it is possible to freely change the color of the front side of the vehicular ceiling interior material. Moreover, in this embodiment, the appearance change of the surface of the spunlace nonwoven fabric 21 is grade B or higher (when the wear wheel CS-10, load 2.45N, and the number of frictions are 50 times in JIS L1096 C method) Since the colored resin impregnates the spunlace nonwoven fabric 21, fraying on the surface of the spunlace nonwoven fabric 21 can be suppressed.

また、積層シート２０の樹脂フィルム２３を、イソシアネート系化合物を含む熱硬化型接着材４１によってウレタン発泡体１１に接着させる構成としたので、イソシアネート系化合物が、表面側、即ち、スパンレース不織布２１側にシミ出してくることを樹脂フィルム２３によって防ぐことができる。   Moreover, since it was set as the structure which adhere | attaches the resin film 23 of the lamination sheet 20 on the urethane foam 11 with the thermosetting type adhesive material 41 containing an isocyanate type compound, an isocyanate type compound is the surface side, ie, the spunlace nonwoven fabric 21 side. It is possible to prevent the resin film 23 from being stained.
