Description

【0001】
【発明の属する技術分野】
この発明は、相互に熱融着したゴム樹脂複合品用の配合ゴムに関するものである。
【0002】
【従来の技術】
自動車のウエザーストリップにおいて、ゴム製ウエザーストリップの一部表面に耐久性・耐候性向上のために樹脂層を設けたものがある。しかし、樹脂層が太陽光線に晒されると変色もしくは退色するのが避けられなかった。
【0003】
【発明が解決しようとする課題】
ゴム体の表面に設けた樹脂層が太陽光線に晒されても、変退色し難いゴム樹脂複合品用の配合ゴムを提供しようとするものである。
【0004】
【課題を解決するための手段】
原料ゴムには、架橋剤・補強材料・配合剤が混合されて加硫前の配合ゴムになる。そして、配合剤には、劣化防止剤・軟化剤・加工助剤・機能性配合剤等が含まれている。この内、軟化剤としては鉱物油系・植物油系・合成系等がある。鉱物系のうち石油系が最も多く使用されており、石油系軟化剤即ちプロセルオイルは、基油の分子構造の違いによりパラフィン系・ナフテン系およびアロマ系に分類される。
【0005】
自動車のウエザーストリップの一部表面に耐久性・耐候性向上のために樹脂層を設けたとき、フェード試験機により紫外線を当てると、樹脂部が変色する不具合があった。本発明者は樹脂部の変色の原因は、プロセスオイル中や加硫促進剤中に含まれているアロマ分(芳香族)が樹脂側に移動し、紫外線により着色性を有する物質になることを見出した。そこでアロマ分が少ないプロセスオイルを選定するか、または/およびアロマ骨格を含む加硫促進剤の配合部数を少なくすることで、変色しない樹脂層を有するウエザーストリップの開発に成功した。
【0006】
図面を参考にして説明する。請求項1の発明に係る熱融着したゴム樹脂複合品用の配合ゴムは、加硫済ゴム体2cに樹脂層3bを熱融着にて貼り合わせることよりなるゴム樹脂複合品1における加硫済ゴム体2c用の配合ゴムであり、軟化剤としてアロマ分が0.5%以下、好ましくはアロマ分が0%のパラフィン系・ナフテン系の少なくとも一方のプロセスオイルを用いるものである。
【0007】
また請求項2の発明に係るゴム樹脂複合品用の配合ゴムは、未加硫ゴム体2bの表面に接触させた樹脂3bを、ゴム加硫時の加熱による熱融着7によって貼り合わせることよりなるゴム樹脂複合品1における未加硫ゴム体2b用の配合ゴムであって、アロマ骨格を持つ加硫促進剤の合計が0.8重量部以下であり、軟化剤としてアロマ分が0.5%以下、好ましくはアロマ分が0%のパラフィン系・ナフテン系の少なくとも一方のプロセスオイルを用いるものである。
【0008】
請求項3の発明に係るゴム樹脂複合品用の配合ゴムは、請求項2の発明においてゴム樹脂複合品1が共押出しされていることを特徴とする。
【0009】
本発明において、樹脂層を形成する樹脂とは、熱可塑性エラストマーを含む熱可塑性樹脂および熱硬化性樹脂をさし、好ましくはオレフィン系熱可塑性エラストマーおよびスチレン系熱可塑性エラストマーであるが、この限りでない。
【0010】
【発明の実施の形態】
図1〜3を参考にして説明する。配合ゴム2a及び原料樹脂3aは押出装置4によって共押出され、未加硫ゴム体2bに未融着状態の樹脂層3bが接触したものとなり、次いで加硫炉5で加熱され加硫済ゴム体2cに樹脂層3cが熱融着したものになり、ゴム樹脂複合品1となる。
【0011】
図3の実施例はゴム樹脂共押出しを示したが、押出加硫済ゴム体2cに樹脂層3bを熱融着にて貼り合わせてゴム樹脂複合品1としてもよい。また、型形加硫済ゴム体2cに樹脂層3bを熱融着にて、貼り合わせてゴム樹脂複合品としてもよい。

BACKGROUND OF THE INVENTION
The present invention relates to a compounded rubber for a rubber resin composite product which is heat-sealed with each other.
[0002]
[Prior art]
Some automobile weather strips are provided with a resin layer on a partial surface of a rubber weather strip to improve durability and weather resistance. However, when the resin layer is exposed to sunlight, it is inevitable that the resin layer changes color or fades.
[0003]
[Problems to be solved by the invention]
An object of the present invention is to provide a compounded rubber for a rubber-resin composite product that hardly discolors even when a resin layer provided on the surface of a rubber body is exposed to sunlight.
[0004]
[Means for Solving the Problems]
The raw rubber is mixed with a crosslinking agent, a reinforcing material, and a compounding agent to form a compounded rubber before vulcanization. The compounding agent includes a deterioration inhibitor, a softening agent, a processing aid, a functional compounding agent, and the like. Among these, softeners include mineral oils, vegetable oils, and synthetics. Petroleum is most commonly used among minerals, and petroleum softeners, ie, process oil, are classified into paraffinic, naphthenic, and aroma based on the difference in the molecular structure of the base oil.
[0005]
When a resin layer was provided on a part of the surface of a weather strip of an automobile to improve durability and weather resistance, there was a problem that the resin part was discolored when irradiated with ultraviolet rays by a fade tester. The present inventor has found that the cause of discoloration of the resin part is that the aroma (aromatic) contained in the process oil or vulcanization accelerator moves to the resin side and becomes a substance having colorability by ultraviolet rays. I found it. Therefore, we have succeeded in developing a weather strip having a resin layer that does not change color by selecting a process oil with a low aroma content or / and reducing the number of blended vulcanization accelerators containing an aroma skeleton.
[0006]
This will be described with reference to the drawings. Compounded rubber for heat sealing rubber resin composite article according to the invention of claim 1, pressurizing the gum resin composite article 1 made of attaching the resin layer 3b by heat fusion 7 vulcanized already rubber body 2c It is a compounded rubber for the vulcanized rubber body 2c and uses, as a softener, at least one paraffinic or naphthenic process oil having an aroma content of 0.5% or less, preferably 0% .
[0007]
Further , in the compounded rubber for a rubber resin composite product according to the invention of claim 2, the resin 3b brought into contact with the surface of the unvulcanized rubber body 2b is bonded by heat fusion 7 by heating at the time of rubber vulcanization. comprising a compounded rubber of rubber resin definitive in a composite article 1 unvulcanized rubber member 2b, the sum of the vulcanization accelerator with aroma skeleton is not more than 0.8 part by weight, the aromatic content as a softening agent 0. At least one of paraffinic and naphthenic process oils having 5% or less, preferably 0% aroma is used.
[0008]
The compounded rubber for a rubber resin composite product according to the invention of claim 3 is characterized in that the rubber resin composite product 1 is coextruded in the invention of claim 2 .
[0009]
In the present invention, the resin forming the resin layer refers to a thermoplastic resin and a thermosetting resin containing a thermoplastic elastomer, preferably an olefin-based thermoplastic elastomer and a styrene-based thermoplastic elastomer, but is not limited thereto. .
[0010]
DETAILED DESCRIPTION OF THE INVENTION
A description will be given with reference to FIGS. The compounded rubber 2a and the raw material resin 3a are co-extruded by the extrusion device 4, and the unvulcanized rubber body 2b comes into contact with the unfused resin layer 3b, and then heated in the vulcanizing furnace 5 and vulcanized rubber body. The resin layer 3c is heat-sealed to 2c, and the rubber resin composite product 1 is obtained.
[0011]
Embodiment of Figure 3 showed a rubber resin coextruded, a resin layer 3b may be rubber resin composite article 1 bonded by heat fusion in an extrusion vulcanized spent rubber member 2c. Further, in the mold formed KatachiKa硫already rubber body 2c in heat-sealing resin layer 3b, it may be rubber resin composite articles bonded.

Formula ΔE = [(ΔL) 2 + (Δa) 2 + (Δb) 2 ] 1/2
This is the value obtained in. The values are listed at the bottom of Table 1.
[0022]
The vulcanized rubber body of the comparative example changes to brown color of TPO or TPS, whereas the vulcanized rubber body of the example does not cause TPO or TPS color change.
[0023]
【The invention's effect】
