Description

Laminate and method for producing the same Technical Field The present invention relates to a technique for joining a plurality of members to each other. Background A technique of joining (bonding) a plurality of members made of different materials using a silane coupling agent has been conventionally proposed. For example, patent document 1 discloses a technique in which a sheet made of silicone rubber and a sheet made of a resin material or a metal material are bonded to each other by a single type of silane coupling agent. Literature of related art Patent literature Patent document 1 Japanese patent application laid-open No. 2014-62224 Disclosure of Invention Problems to be solved by the invention However, in a state where a single type of silane coupling agent is used, it is difficult to sufficiently secure the bonding durability between the components, and a problem (for example, detachment of one of the components from the other component) tends to occur, especially in a high humidity environment. In view of the above, an object of an aspect of the present disclosure is to sufficiently ensure durability of mutual engagement of a first member and a second member. Means for solving the problems According to one aspect of the present invention, a laminate includes a first member made of silicone rubber, a second member made of polystyrene, and an adhesive layer joining a first surface of the first member and a second surface of the second member to each other, wherein the adhesive layer includes a first layer disposed on the first surface, the first layer being made of a silane coupling agent having an epoxy group, and a second layer disposed on the second surface, the second layer being made of a silane coupling agent having an amino group. According to another aspect of the invention, a method of producing a laminate includes a first applying step of applying a first adhesive to a first surface of a first part, the first part being made of silicone rubber, the first adhesive including a silane coupling agent having an epoxy group, a second applying step of applying a second adhesive to a second surface of a second part, the second part being made of polystyrene, the second adhesive including a silane coupling agent having an amino group, and a bonding step of bonding the first surface of the first part and the second surface of the second part to each other with the first adhesive and the second adhesive. The order of the first application step and the second application step can be freely selected. For example, the above-described aspects include a mode in which the second application step is performed after the first application step is performed, a mode in which the first application step is performed after the second application step is performed, or a mode in which the first application step and the second application step are partially or entirely performed in parallel. Effects of the invention According to the present invention, durability of the mutual engagement of the first member and the second member can be sufficiently ensured.

Fig. 3 is a flow chart showing the production process of the laminate. Detailed Description A laminated board Fig. 1 is a cross-section of a laminate 100 according to an embodiment of the invention. The laminate 100 according to an embodiment of the present invention is, for example, a culture plate (WELL PLATE) for culturing various types of cells (more specifically, spherical cells), and includes a first member 10, a second member 20, and an adhesive layer 30. The first member 10 is a molded body (molded body) of a thin plate shape made of silicone rubber. In other words, the first component 10 is a component comprising a silicone rubber material. The silicone rubber is, for example, polydimethylsiloxane (olydimethylsiloxane, PDMS). The first component 10 comprises a first surface 11. The first surface 11 is provided with a number of small grooves (not shown). For example, the grooves are each hemispherical grooves having a diameter of about 1 millimeter. The second member 20 is a molded body made of Polystyrene (PS) in a thin plate shape. In other words, the second part 20 is a part comprising polystyrene material.
