Abstract

PURPOSE:To provide a method for manufacturing an elastic connector having high resolution with high accuracy. CONSTITUTION:In manufacturing an elastic connector, a conductive elastomer layer is formed by a calendar roll, and nonconductive elastomer layer is formed of liquid silicon rubber not including a filler by a coater. The layers are laminated on each other and formed into a sheet with at least one of the layers non- hardened. A number of sheets are laminated, followed by pressurizing and heating for hardening, to be thus cut at a surface perpendicular to the laminated surface.

不利がある。However, in this conventional method, the molding of the conductive elastomer layer and the non-conductive elastomer layer in step A) is performed by using a calender roll. Depending on the silica content of the elastomer raw material and the non-conductive elastomer raw material, and the presence or absence of carbon filling, this conductive elastomer layer can be manufactured with a calender roll having a thickness of 25 to 35 μm, but the non-conductive elastomer is For layers with a thickness of 30 μm or less, pinholes frequently occur when molded with a calender roll, electrical insulation cannot be maintained, transfer from the calender roll becomes poor, and this non-conductive elastomer layer is a millable type. It contains silica etc. because it uses the silicone rubber of If the thickness is thinner than m, the filler agglomerates easily to cause unevenness or pinholes on the sheet surface, and if the thickness is less than 30 μm, there is no freedom in molding conditions, and the molding yield of the thin sheet is also disadvantageous.

After molding the non-conductive elastomer layer with a liquid silicone rubber containing no filler using a coater, at least one of these layers is laminated in an uncured state to form a sheet, and a number of these are laminated and cured by heating under pressure, Then, this is cut by a plane perpendicular to the stacking direction.

本発明を完成させた。以下にこれをさらに詳述する。That is, as a result of various investigations by the present inventor to develop a method for producing a higher-definition and higher-resolution elastic connector, the conductive elastomer layer is formed by a known calender roll, but the non-conductive elastomer layer If a liquid silicone rubber containing no filler is molded with a coater, it should be 30 μm or less, especially 5
It was found that the thickness can be as thin as about 20 μm, and therefore, a sheet is prepared by laminating the conductive elastomer layer and the non-conductive elastomer layer, and when the elastic connector is made according to a known method below, the conductive elastic layer is formed. The present invention has been completed by confirming that a non-conductive elastic layer can be thinner than a conventional product and that a high-definition and high-resolution elastic connector can also be obtained. This will be described in more detail below.

たものとされる。The method for producing an elastic connector of the present invention is characterized by a method for producing a sheet obtained by laminating a conductive elastomer layer as a starting material and a non-conductive elastomer layer. The conductive elastomer layer used here may be a conventionally known one, which is made of silicone rubber, Ketjen Black EC, acetylene black,
It is supposed to be molded from a conductive silicone rubber composition in which carbon black such as graphite and a filler such as silica are mixed.

ダイコーターとすることがよい。The non-conductive elastomer layer used here is also formed of silicone rubber. If the silicone rubber contains a filler such as silica, the agglomeration of the sheet causes unevenness of the sheet. Since it tends to have pinholes and electrical insulation cannot be maintained, it is necessary to use no filler, and pinholes may occur when molding with a calender roll. Solvent-free liquid silicone rubber (viscosity of 50 to 1,000 poise) that does not contain this is preferably used as a film formed by a coater, for example, a top feed roll roller coater or a die coater. Is less than 30 μm, 5 to 20 μm
It can also be a sheet. Note that this coater is preferably a die coater capable of supplying the liquid silicone rubber in a hermetically sealed state, in consideration of the viscosity of the liquid silicone rubber, safety, and measures against contamination by foreign matter.

Below, 100 poise or less is preferable in consideration of the self-fluidity of the raw material, but solvent-free type is preferable in consideration of stability during molding. The sheet made with this coater should have a tear strength (JIS K630 / A type) of 10 kgf / cm due to its physical properties when wound.
