Description
【０００１】0001
本考案は、各種エレクトロニクス機器のスイッチの入力部、特に接点ゴムスイ ッチのシリコーンゴム入力部に関するものである。 This invention applies to input parts of switches of various electronic devices, especially contact rubber switches. This relates to the silicone rubber input part of the switch.
【０００２】0002
従来の接点ゴムはシリコーンゴムで成型され、何等の表面処理をしていないも のか、使用する材料を耐油性を有するシリコーンとアクリル、あるいはシリコー ンとＥＰＤＭの共重合ゴム、もしくはフロロシリコーンゴムとしているもの、さ らにはレジンにてコーティングをしているものが存する。 Conventional contact rubber is molded from silicone rubber and does not have any surface treatment. Is the material used oil-resistant silicone and acrylic, or silicone? and EPDM copolymer rubber, or fluorosilicone rubber, Some of them are coated with resin.
【０００３】0003
従来の接点ゴムは、耐熱性、加工性に優れるシリコーンゴムを使用しているも のがほとんどあり、これは耐熱性に劣るため長期間使用していると、油脂類や機 械油等の油状物質により接点ゴムが膨潤してしまったり、導電部に折出して導通 不良が生じる欠点があった。また、シリコーンとアクリル、あるいはＥＰＤＭと の共重合ゴムは、耐油性は存するが、耐熱性および加工性が悪い欠点がある。そ してフロロシリコーンゴムも加工性が悪い上に高価となる欠点がある。 Conventional contact rubber uses silicone rubber, which has excellent heat resistance and processability. Most of them have poor heat resistance, so if you use them for a long time, they will be exposed to oils and machinery. The contact rubber may swell due to oily substances such as machine oil, or it may break out on the conductive part and cause electrical continuity. There was a drawback that defects occurred. Also, silicone and acrylic or EPDM and Although the copolymer rubber has oil resistance, it has the drawbacks of poor heat resistance and processability. So Fluorosilicone rubber also has the drawbacks of poor processability and high cost.
【０００４】 さらにレジンのコーティングにあっては、硬いためゴムの弾性力に追従できず クリークが生じる欠点が存した。0004 Furthermore, resin coatings are hard and cannot follow the elasticity of rubber. There was a drawback that cliques occurred.
【０００５】[0005]
そこで本発明は、シリコーンゴムの加工性に優る点をいかし、シリコーンゴム にて接点ゴム入力部を成型したのちに、その表面を耐熱性を有する含フッ素合成 ゴムを適当な溶媒に溶かし、必要に応じ触媒等を添加してコーティング剤とし、 その後ＥＢ加硫や、過酸化物加硫を行なうことで、透明な耐油被覆を形成した。 Therefore, the present invention takes advantage of the superior processability of silicone rubber to create silicone rubber. After molding the contact rubber input part, its surface is coated with a heat-resistant fluorine-containing synthetic material. Dissolve the rubber in a suitable solvent and add a catalyst as necessary to make a coating agent. Thereafter, EB vulcanization and peroxide vulcanization were performed to form a transparent oil-resistant coating.
【０００６】 この含フッ素合成ゴムとしては、フッ化ビニリデン−クロロトリフルオロエチ レン共重合体、フッ化ビニリデン−ヘキサフルオロフロペン共重合体、あるいは フッ化ビニリデン−１，２，３，３・３ペンタフルオロプロペン共重合体等のフ ッ素ゴム、またはフロロシリコーンゴム、あるいはフロロフォスファゼンゴム等 のフッ素無機ゴムが挙げられる。これらから成る耐油被覆は、表面張力が低いた め、ヌレ性の悪いシリコーンゴムの表面に良く展開して密着する。そしてゴム弾 性を有するために被覆にクリークが入るという問題も無くなる。[0006] As this fluorine-containing synthetic rubber, vinylidene fluoride-chlorotrifluoroethylene Ren copolymer, vinylidene fluoride-hexafluorofuropene copolymer, or Fluorine such as vinylidene fluoride-1,2,3,3.3pentafluoropropene copolymer Fluorine rubber, fluorosilicone rubber, fluorophosphazene rubber, etc. Examples include fluorinated inorganic rubber. Oil-resistant coatings made of these materials have low surface tension. Therefore, it spreads well and adheres well to the surface of silicone rubber, which has poor wettability. and rubber bullets This also eliminates the problem of cliques entering the coating.

Co., Ltd.) is applied to the molded silicone rubber input part 1. After drying, it was vulcanized at 170° C. to form a heat-resistant coating 2.
【０００９】 実施例１および２により成型加工した含フッ素合成ゴムの被覆をしたシリコー ンゴム入力部と、何等の被覆をしないシリコーンゴム入力部のそれぞれの表面上 に多量のラードを浸した綿をのせ、６０℃雰囲気中に１０日間放置したところ被 覆をしていないシリコーンゴム入力部の方のベース部は、大きく膨潤した。しか し含フッ素合成ゴムの被覆を施した入力部の方のベース部は膨潤しなかった。[0009] Silicone coated with fluorine-containing synthetic rubber molded according to Examples 1 and 2 on the surfaces of the silicone rubber input section and the silicone rubber input section without any coating. When cotton soaked in a large amount of lard was placed on a cloth and left in an atmosphere of 60℃ for 10 days, it was covered. The base of the uncovered silicone rubber input section swelled significantly. deer However, the base portion of the input portion coated with fluorine-containing synthetic rubber did not swell.
【００１０】 これは、表面にのせたラードが、含フッ素合成ゴムの被覆をした本考案の入力 部にあっては、このラードが被覆にて遮断され、ベース部へ浸透していかなかっ たことを示す。0010 This is the input of this invention in which the lard placed on the surface is covered with fluorine-containing synthetic rubber. In the base part, this lard is blocked by the coating and does not penetrate into the base part. to show that
【００１１】[0011]
本考案は、シリコーンゴムの表面に透明な耐熱被覆を形成するため、シリコー ンの加工性を損なわず、そして塗布等によりコーティングするので工程が簡単で あり、しかも表面コーティングのみに含フッ素合成ゴムを使用するので安価であ る。そして弾性を有する合成ゴム被覆であるため、シリコーンゴム入力部の物性 も損なわない。 This invention uses silicone rubber to form a transparent heat-resistant coating on the surface of silicone rubber. The process is simple because it does not impair the workability of the material, and it is coated by coating. Yes, and because fluorine-containing synthetic rubber is used only for the surface coating, it is inexpensive. Ru. And since it is covered with elastic synthetic rubber, the physical properties of the silicone rubber input part It doesn't hurt either.
