Description

本発明は、ゴム又は樹脂よりなる押出成形体の表面に布貼りした装飾体の製造法に関する。   The present invention relates to a method for producing a decorative body having a cloth attached to the surface of an extrusion-molded body made of rubber or resin.

装飾体は、例えば家具、電化製品、車両の内装材など様々な用途に用いられており、その一つにＥＰＤＭ等のゴムよりなる押出成形体の表面に布貼りした自動車用のオープニングシールがある。図１は、その一例である、車体のドア開口縁に取付けられ、ドアとの間をシールするウェザーストリップについて示すもので、このウェザーストリップ１は、断面略Ｕ形状をなし、内側に係止リップ２を対向して突設した取付部３と、該取付部３の一側より突設される中空状のシール部４よりなり、取付部３の表面には布帛５が布貼りされている。図中、６は芯金である。   The decorative body is used for various applications such as furniture, electrical appliances, and vehicle interior materials, and one of them is an opening seal for automobiles that is bonded to the surface of an extruded body made of rubber such as EPDM. . FIG. 1 shows an example of a weather strip that is attached to a door opening edge of a vehicle body and seals between the doors. The weather strip 1 has a substantially U-shaped cross section and has a locking lip on the inside. 2, and a hollow seal portion 4 protruding from one side of the mounting portion 3, and a fabric 5 is affixed to the surface of the mounting portion 3. In the figure, 6 is a cored bar.

図２は、ウェザーストリップ１の製造装置についての例を示すもので、押出ヘッド７の口金８より同時に押出成形されたウェザーストリップ１は加硫装置９で加硫されたのち、裏地に熱融着接着剤を塗布した布帛５が圧着ローラ１０より圧着して接着されるようになっている。   FIG. 2 shows an example of an apparatus for producing a weather strip 1. The weather strip 1 extruded simultaneously from the base 8 of the extrusion head 7 is vulcanized by a vulcanizer 9 and then heat-sealed to the backing. The fabric 5 to which the adhesive is applied is pressed and bonded by the pressing roller 10.

上述する従来の製造法では、裏地に接着剤を塗布した布帛を押出成形体に圧着して貼着しているが、接着剤を塗布した布帛はコスト高で、成形体がＥＰＤＭ等のゴムである場合、加硫後に接着加工を行う工程が必要である。   In the conventional manufacturing method described above, a fabric coated with an adhesive is bonded to an extruded product by pressing, but the fabric coated with an adhesive is expensive and the molded product is made of rubber such as EPDM. In some cases, a process of bonding after vulcanization is required.

本発明は、接着剤を塗布した布帛を用いないで製造コストを低減させ、また接着加工を行う工程を有していても、そのため製造時間が長くなることがないようにした装飾体の製造法を提供することを目的とする。   The present invention relates to a method for manufacturing a decorative body that reduces the manufacturing cost without using a fabric coated with an adhesive and does not increase the manufacturing time even if it has a step of performing an adhesive process. The purpose is to provide.

請求項１に係る発明の装飾体の製造法は、ゴム又は樹脂を口金より所定の断面形状で押出す押出工程と、口金より押出されたゴム又は樹脂よりなる成形体が融着可能な状態の間に布帛を圧着手段により圧着して接着する接着工程を有することを特徴とする。   The manufacturing method of the decorative body of the invention according to claim 1 is a state in which the extrusion process of extruding rubber or resin in a predetermined cross-sectional shape from the die and the molded body made of rubber or resin extruded from the die can be fused. It is characterized by having an adhering step in which the cloth is bonded by pressing with a pressing means.

本発明で用いる布帛は、パイル織物やパイル編物等のパイル地、起毛織物や起毛編物等、繊維が成形体のゴムや樹脂に入り込んでアンカー効果を持たせ、接着が強固に行われるようにするのが望ましく、成形体が樹脂である場合には、成形体と同材質又は類似の接着性の良好な材質のものを用いるのが望ましい。これにより成形体と布帛の接着強度を高めることができる。なお成形体がゴムである場合には、布帛を接着後、加硫されるため布帛には加硫温度に耐えられる耐熱性のあるもの、例えば成形体がＥＰＤＭのゴムの場合、融点が２６５℃で、ＥＰＤＭの加硫温度より融点の高いポリエステル繊維が好適に用いられる。   The fabric used in the present invention is a pile fabric such as a pile woven fabric or a pile knitted fabric, a raised woven fabric or a raised knitted fabric, or the like, in which the fibers enter the rubber or resin of the molded body to have an anchor effect so that the adhesion is firmly performed. When the molded body is a resin, it is desirable to use the same material as that of the molded body or a similar material having good adhesion. Thereby, the adhesive strength of a molded object and a fabric can be raised. When the molded body is rubber, the cloth is vulcanized after being bonded, and therefore the cloth has heat resistance that can withstand the vulcanization temperature. For example, when the molded body is EPDM rubber, the melting point is 265 ° C. Polyester fibers having a melting point higher than the vulcanization temperature of EPDM are preferably used.

圧着手段としては、例えば圧着ローラを用いることができる。   As the pressure bonding means, for example, a pressure roller can be used.

請求項２に係る発明は、請求項１に係る発明における布帛がパイル地或いは起毛織物ないし起毛編物であることを特徴とし、
請求項３に係る発明は、請求項１又は２に係る発明において、成形体と布帛が同材質又は類似の互いに接着性の良好な樹脂であることを特徴とする。 The invention according to claim 2 is characterized in that the fabric in the invention according to claim 1 is a pile fabric or a raised woven fabric or a raised knitted fabric,
The invention according to claim 3 is characterized in that, in the invention according to claim 1 or 2, the molded body and the fabric are the same material or a similar resin having good adhesion to each other.

本発明において、成形体が例えばオレフィン系熱可塑性エラストマーである場合、布帛の繊維には例えばポリエチレン、ポリプロピレン等のポリオレフィンよりなるものが、スチレン系熱可塑性エラストマーである場合、ポリスチレンよりなるものが、ウレタン系熱可塑性エラストマーの場合、ポリウレタンよりなるものが、またエステル系熱可塑性エラストマーの場合、ポリエステルよりなるものが用いられる。   In the present invention, when the molded body is, for example, an olefin-based thermoplastic elastomer, the fabric fiber is made of polyolefin such as polyethylene or polypropylene, and when it is a styrene-based thermoplastic elastomer, it is made of polystyrene. In the case of thermoplastic elastomers, those made of polyurethane are used, and in the case of ester thermoplastic elastomers, those made of polyester are used.

請求項１に係る発明によると、布帛には接着剤を塗布した布帛を用いなくてもよいため安価な布帛を使用することができ、装飾体の製造コストを下げることができること、布帛の接着は、押出成形直後の成形体が溶融状態の間に行われ、冷却後に行われる訳ではないので、接着加工を要しない製造法に比べ製造時間に変わりがなく、接着加工を行うことによって生産性が低下する、といった問題を生ずることもないこと等の効果を奏する。   According to the first aspect of the present invention, it is not necessary to use a cloth coated with an adhesive as the cloth, so that an inexpensive cloth can be used, the manufacturing cost of the decorative body can be reduced, and the cloth can be bonded. Since the molded body immediately after extrusion molding is performed in a molten state and is not performed after cooling, the manufacturing time is not changed compared to a manufacturing method that does not require adhesive processing, and productivity is improved by performing adhesive processing. There is an effect that the problem of lowering does not occur.

請求項２及び３に係る発明によると、布帛の接着強度が高まり、布帛が容易に剥離することがない。   According to the invention which concerns on Claim 2 and 3, the adhesive strength of a cloth increases and a cloth does not peel easily.

以下、本発明の実施形態について図面により説明する。   Hereinafter, embodiments of the present invention will be described with reference to the drawings.

図３は、本発明に係る装飾体の製造装置の概要を示すもので、押出ヘッド１１の口金１２よりなるＥＰＤＭ等のゴムよりなる押出成形体１３には、押出直後の溶融状態においてポリエステル繊維よりなるパイル織物の布帛１４が口金出口１２に設けた圧着ローラ１５により圧着されて接着され、ついで加硫装置１６により加硫されるようになっている。図４は、本製造装置によって得られるウェザーストリップを示す。   FIG. 3 shows an outline of the decorative body manufacturing apparatus according to the present invention. An extruded body 13 made of rubber such as EPDM made of a die 12 of an extrusion head 11 is made of polyester fiber in a molten state immediately after extrusion. A pile woven fabric 14 is pressed and bonded by a pressing roller 15 provided at the mouthpiece outlet 12, and then vulcanized by a vulcanizing device 16. FIG. 4 shows a weather strip obtained by the production apparatus.

なお、図４に示すようなウェザーストリップ１を製造するに際し、圧着ローラ１５が取付部３とシール部４の間のコーナ部の布帛１４の端部に届かず、該端部を圧着できない場合には、圧着ローラ１５をコーンローラとするか、圧着ローラ１５のほかに別にコーンローラを設け、コーンローラの先端部で取付部３とシール部４の間のコーナ部の布帛端部を圧着させるようにするとよい。   When the weather strip 1 as shown in FIG. 4 is manufactured, the pressure roller 15 does not reach the end of the fabric 14 at the corner portion between the mounting portion 3 and the seal portion 4, and the end portion cannot be crimped. The pressure roller 15 is a cone roller, or another cone roller is provided in addition to the pressure roller 15, and the end of the cone roller is crimped at the corner of the corner between the mounting portion 3 and the seal portion 4. It is good to make it.

本装置によると、布帛１４は接着剤を塗布したものに比べ、接着剤を塗布しない分、安価であり、製造コストが低減されること、布帛はパイル地であるためパイルがゴムに入り込んでアンカー効果をもたらし、接着強度が高められること、布帛はポリエステル繊維よりなり、融点が加硫温度より高いため、加硫時に溶融することがないこと、布帛の接着は、押出から加硫までの時間内で行われ、接着のために新たな時間を要しないため生産性の低下を生ずることがないこと等の効果を奏する。   According to the present apparatus, the fabric 14 is less expensive and less expensive to manufacture than the one coated with an adhesive, and the manufacturing cost is reduced. Since the fabric is a pile fabric, the pile enters the rubber and anchors. It has an effect, the adhesive strength is increased, the fabric is made of polyester fiber, and the melting point is higher than the vulcanization temperature, so that it does not melt at the time of vulcanization, and the fabric is adhered within the time from extrusion to vulcanization. In this case, there is no need for a new time for bonding, so that the productivity is not lowered.

本発明は、表面の装飾性が望まれる各種の用途、例えば家具、電化製品、車両の内装材、ウェザーストリップ等の装飾体を製造するのに用いることができる。   The present invention can be used to manufacture decorative objects such as furniture, electrical appliances, vehicle interior materials, weather strips, and the like for which surface decorativeness is desired.
