取付け孔、10はリード線用孔である。The construction of a door mirror bracket used to attach a door mirror to a cashmere door is generally as shown in FIGS. That is, the mirror mounting portion 1
Has an outer shape that occupies a corner portion between the upper edge of the door body and the front pillar when the door is closed, and has a glass storage groove 3 whose bottom is the front pillar contact side. A glass run portion 5 composed of a pair of strip rips 4, 4 which are close to each other on the tip side is provided at the opening edge facing the sandwiched corner portion. Reference numeral 6 is a mounting leg portion for fixing to the door body 11. Here, the mirror mounting portion 1 is formed by a sheet metal U-shaped insert 7 and a coating portion 8 made of a polymeric elastic material, and the glass run portion 5 is formed.
Is formed by extending the covering portion 8. Reference numeral 9 is a mirror mounting hole, and 10 is a lead wire hole.
この成形材料としては、従来からグラスラン等に使用さ
れてきたエチレンプロピレンゴム(EPR)が使用されて
いた。As this molding material, ethylene propylene rubber (EPR) which has been used for grass run etc. has been used.
このEPR成形体は、そのままでは一般に摩擦係数が高
く、ミラーブラケツトの上記グラスラン部5のガラス摺
動抵抗が高くなるため、通常、ウレタン塗料やシリコー
ンオイルで該部位の滑性処理をしていた。This EPR molded body generally has a high friction coefficient as it is, and the glass sliding resistance of the glass run portion 5 of the mirror bracket becomes high. Therefore, the surface of the EPR molded body is usually lubricated with urethane paint or silicone oil.
しかし、ウレタン塗料を使用する場合は、前処理(プラ

コーンオイルの場合はオイルが付着してガラスが汚染さ

出して、摺動抵抗が再び増大するとともに、摩耗で発生
するゴム微粉の付着によりガラスが黒く汚染された。However, when urethane paint is used, pretreatment (primer treatment, etc.) is required, and the number of manufacturing steps increases, and in the case of silicone oil, the oil adheres to contaminate the glass, and the coating film after both ages. The rubber surface was exposed due to falling off, the sliding resistance was increased again, and the glass was contaminated in black due to the adhesion of rubber fine powder generated by abrasion.
そこで、本出願人と同一人から、グラスラン部における
摺動抵抗低減のために表面処理をしなくってもよいドア
ミラーブラケツト成形用のNBR/PVCゴム組成物が提案さ
れている(特開昭60−234046号公報参照)。Therefore, the same applicant has proposed an NBR / PVC rubber composition for door mirror bracket molding which does not require surface treatment for reducing sliding resistance in the grass run portion (Japanese Patent Laid-Open No. 60- 234046).
<発明が解決しようとする課題> しかし、上記NBR/PVCゴム組成物では、ある程度の摺動
抵抗低減効果は得られるが、圧縮永久歪が増大する傾向
にあつた。その理由は、射出成形性および耐オゾン性の
見地からNBRのタイプとして高ニトリル(AN量:36〜42
%)を使用しているためと推定される。<Problems to be Solved by the Invention> However, with the NBR / PVC rubber composition, although the sliding resistance reducing effect can be obtained to some extent, the compression set tends to increase. The reason is that from the viewpoint of injection moldability and ozone resistance, high nitrile (AN amount: 36 to 42
%) Is used.
そして、昨今のガラスランには、高シール性が従来にも
増して要求されるようになり、反発弾性および耐圧縮永
久性の向上が要求されるようになつてきている。Further, the glass run of recent years is required to have a higher sealing property than ever before, and is required to be improved in impact resilience and compression permanent resistance.
本発明は、上記にかんがみて、摺動抵抗を余り増大させ
ず、かつ耐オゾン性をほとんど低下させずに、反発弾性
および耐圧縮永久歪性の向上を図ることができるNBR/PV
Cゴム組成物を提供することを目的とする。In view of the above, the present invention makes it possible to improve the impact resilience and the compression set resistance without significantly increasing the sliding resistance and substantially reducing the ozone resistance.
It is intended to provide a C rubber composition.
<課題を解決するための手段> 本発明のNBR/PVCゴム組成物は、上記課題を、下記手段
により解決するものである。<Means for Solving the Problems> The NBR / PVC rubber composition of the present invention solves the above problems by the following means.
ガラス摺動部を具備するドアミラーブラケットの材料と

phr配合されたNBR/PVCゴム組成物において、 NBR/PVCのPVC含量が15〜30%であり、 NBRのタイプが中ニトリルまたは中高ニトリルであ
り、 ポリ塩化ビニルの重合度=1000〜1500であり、 カーボンブラツクの粒径が30〜80mμである、ことを
特徴とする。Used as a material for door mirror brackets equipped with glass sliding parts.
In NBR / PVC rubber composition compounded with phr, PVC content of NBR / PVC is 15 ~ 30%, NBR type is medium nitrile or medium high nitrile, and degree of polymerization of polyvinyl chloride is 1000 ~ 1500. The carbon black has a particle size of 30 to 80 mμ.
<手段の解説> (1)ベースポリマーは、下記要件を満たすNBR/PVCで
ある。<Explanation of Means> (1) The base polymer is NBR / PVC that satisfies the following requirements.
PVC含量が15〜30%である。15%未満では、耐オゾン
性、耐摩耗性等において問題が生じやすく、かつ、摺動
抵抗が増大して望ましくない。他方、30%を超えると、
反発弾性および耐圧縮永久歪性の向上が期待できない。PVC content is 15-30%. If it is less than 15%, problems such as ozone resistance and abrasion resistance tend to occur, and sliding resistance increases, which is not desirable. On the other hand, if it exceeds 30%,
Improvements in impact resilience and compression set resistance cannot be expected.
NBRは、ポリブレンド性、耐寒性、耐圧縮永久歪性等

悪く、かつ、強度的にも問題を生じやすくなる。他方、
AN量が高すぎると、本発明の主目的である反発弾性およ
び耐圧縮永久歪性の向上を期待できない。NBR is based on the balance of the above required physical properties such as polyblendability, cold resistance, and compression set resistance.
Amount: 25-30%) and medium-high nitrile (AN amount: 31-35%). If the amount of AN is too low, the blending property with PVC is poor and the strength tends to be a problem. On the other hand,
If the amount of AN is too high, improvement in impact resilience and compression set resistance, which are the main objects of the present invention, cannot be expected.
PVCは、耐圧縮永久歪性の見地から、重合度=1000
〜1500のものを使用する。この重合度は高い方が望まし
い。重合度が高くなりすぎると、ポリマーの粘度が増大
して成形性に問題を生じやすくなる。The degree of polymerization of PVC is 1000 from the viewpoint of compression set resistance.
Use ~ 1500. It is desirable that the degree of polymerization is high. If the degree of polymerization is too high, the viscosity of the polymer increases and problems with moldability tend to occur.

じやすくなる。(2) The above NBR / PVC has a carbon black and is usually NBR.
And other auxiliary materials to be blended with, namely zinc white, vulcanizing agent, vulcanization accelerator, plasticizer, antiaging agent, etc. The carbon black must have a particle size of 30 to 80 mμ. If it is less than 30 μm, the dispersibility is poor, and 80 μm
If it exceeds m, problems tend to occur in impact resilience and tensile strength.

定の強度を得がたく、80部を超えると圧縮永久歪、反発
弾性において問題を生じやすくなる。The amount of carbon black is usually 30 to 80 parts per 100 parts of NBR / PVC. If it is less than 30 parts, it is difficult to obtain a predetermined strength for the vulcanized product, and if it exceeds 80 parts, problems tend to occur in compression set and impact resilience.

以上を併用して使用する。(3) A lubricant is added to the above NBR / PVC from the viewpoint of reducing sliding resistance. Examples of the lubricant include paraffin waxes, paraffin synthetic waxes, ester waxes, polyethylene waxes and higher alcohols described in the above publications, as well as paraffin process oils, silicone oils and higher fatty acid amides. , Or a combination of two or more.
