【発明の詳細な説明】
〔産業上の利用分野〕
この発明は自動車内装材の一構成材として使用される芯
材に特徴を有する自動車内装材に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an automobile interior material having a characteristic core material used as a component of the automobile interior material.
自動車内装材の芯材としては従来、ポリプロピレン樹脂
にパルプを分散させたもの、紙質ダンボール、繊維ボー
ド、スチレン系樹脂発泡体の両面に樹脂フィルムを貼合
せたもの等が開発され表皮材を貼合せて内装材として使
用されている。Conventionally, core materials for automobile interior materials have been developed such as polypropylene resin with pulp dispersed in it, paper cardboard, fiberboard, and styrene resin foam with resin films laminated on both sides. It is used as an interior material.
ところが前二者のパルプを使用するものは湿度に影響さ
れやすく、形状変化が起る欠点がある。その他のものは
原価面の問題がある。However, those using the former two types of pulp have the disadvantage that they are easily affected by humidity and change in shape. Others have cost issues.
本発明はこのような問題を解決することを目的とし特殊

のである。The present invention aims to solve these problems and has been achieved by reusing special carpet scraps.
即ち、繊維の大部分がポリプロピレン繊維からなるカー

。That is, the core material is formed by extruding a blend of recycled material recycled from carpet scraps, most of which are polypropylene fibers, and polypropylene resin.
繊維の大部分がポリプロピレンといつ意味は望ましくは

維、例えばナイロン繊維ではポリエステル繊維以上に品
質を著しく低下させるので繊維量の１０部程度までなら
実用上問題はないがそれ以上は衝撃強度等の物性低下が
大きく問題である。When most of the fibers are polypropylene, this means that preferably all the fibers are made of polypropylene, but in reality, tufted carpets for automobiles often use a base fabric made of polyester fibers. . Therefore, not all fibers are polypropylene fibers, but this amount is enough to cause no problems in terms of production or quality. The permissible amount of polyester fiber is approximately 30% of the amount of fiber. If the amount exceeds this value, it will cause problems in terms of manufacturing and product quality. That is, in terms of production, since the polyester does not melt in the extruder, there is a problem in that the die gets clogged or the breaker gets clogged in a short period of time, and in terms of quality, the cold impact resistance decreases. Other fibers, such as nylon fibers, have a significantly lower quality than polyester fibers, so if the amount of fiber is less than about 10 parts, there is no practical problem, but if it exceeds that amount, the physical properties such as impact strength are significantly reduced, which is a problem.
カーペットとしてはタフトカーペット、ニードルカーペ
ットが一般に使用されている。Tufted carpets and needle carpets are commonly used as carpets.
カーペットの裏面にはポリエチレンやエチレン・酢酸ビ
ニル樹脂が場合により炭酸カルシウム等の無機フィラー
を配合したものが被覆加工されている。The back side of the carpet is coated with polyethylene or ethylene/vinyl acetate resin, sometimes mixed with an inorganic filler such as calcium carbonate.
上記自動車カーペットは成形され、外周裁断打抜加工等
され、その裁断打抜工程においてカーペット端材が多量
発生する。The above-mentioned automobile carpet is molded and subjected to cutting and punching on the outer periphery, and a large amount of carpet scraps are generated during the cutting and punching process.
本発明はこの鋼材を有効活用して低コストで湿度に影響
されない芯材を開発したのである。The present invention effectively utilizes this steel material to develop a core material that is low cost and unaffected by humidity.

させることができる。The manufacturing method is to rough cut carpet scraps, add resin if necessary, knead them in a Banbury mixer, etc., form them into sheets with a calendar, and then crush them, either as they are or as recycled material in the form of chips with an extruder. . When recycled material and polypropylene are blended and extruded into a sheet, it becomes a core material. Usually, the interior material is manufactured by laminating the skin material at the same time as forming the core material, or alternatively, the steel material is roughly cut and crushed, and then resin is added and blended as necessary using a high-speed agitator such as a Henschel mixer, and then the material is mixed for a certain period of time. When stirred at high speed, it becomes a granular material, which can be mixed with polypropylene chips and formed into a sheet using an extruder.

溶性よく混ざり合ったシートができる。When recycled carpet scraps and polypropylene chips are mixed and formed into a sheet using an extruder, the polypropylene fibers are melted by heat in the extruder, and the polyethylene, ethylene/vinyl acetate, and Furthermore, a sheet is produced that is highly compatible with the newly blended polypropylene resin.

が悪ろくなる。In the case of nylon fibers, the nylon melted in the extruder has poor compatibility with other resins, resulting in poor sheet properties.
ポリエステル繊維の場合は押出機中で溶融しないため前
記したような問題が発生する。In the case of polyester fibers, the above-mentioned problems occur because they do not melt in the extruder.

The back side of the carpet greige machine impregnated with i/m'' and dried was coated with polyethylene resin 4009/G by melting to prepare a raw material for automobile carpet.The steel material of this carpet was roughly cut and crushed in a crusher, and then crushed at high speed in a Hensel mixer. Stir to form a granular shape. Next, 50 parts of this granular recycled material is mixed with 50 parts of polypropylene chips while extruding 2.5 parts of the recycled material into a granular shape.
Ky/m'' sheet was extruded and simultaneously laminated with a chain stitch non-woven skin material to make the interior material.It has excellent physical properties such as rigidity and impact resistance, good stability against humidity, and excellent hot-cold-opening moldability. The interior material has been completed.It is suitable as a trunk interior wall material.
