Definitions
- the present invention relates to an insert molded product, a device using the insert molded product, and a method for manufacturing the insert molded product.
- Insert molding is a method of manufacturing a molded product by injecting resin around a metal core.
- the bonding between the core material and the resin is only due to the close contact between them or the shrinkage pressure of the resin after molding. For this reason, the bonding force between the core material and the resin is insufficient, and it is difficult to obtain a molded product having water tightness.
- Patent Document 1 At least the outer surface of the core material has a metal anticorrosion layer, a sealing layer is deposited on the anticorrosion layer, and a resin is injected outside the sealing layer.

- the insert molded product according to the first embodiment is formed on at least a part of the surface of the first member having at least a surface conductive, and Si, Ti, Al, Zr, Zn, Cr, A surface layer containing at least one elemental compound selected from Ni, Fe, Mo, B, Be, In and Sn, and formed on at least a part of the surface layer so as to be in close contact with the surface layer And a resin part.
- a typical example of the insert-molded product is a metal resin composite material.
- FIG. 1 is a schematic cross-sectional view of a boundary surface between a first member, a surface layer, and a resin portion in an insert molded product according to the present embodiment.
- the insert molded product has a surface layer 3 on the surface of the first member 2 and a resin portion 4 on the surface layer 3.
- Such an insert-molded product is manufactured by using the first member 2 having the surface layer 3 previously formed on the surface as a core material in insert molding, and injecting resin onto the surface layer 3 to form the resin portion 4. To do.
- the first member is conductive.
- the first member may be entirely made of a conductive material. Or you may be comprised from the base
- the shape of the first member may be any shape according to the target molded product.
- the first member is made of a conductive material
- the first member is made of, for example, stainless steel, titanium, nickel titanium (NiTi), silicon steel, cobalt, gold, palladium, nickel, chrome, tungsten, and carbon. Composed of a material selected from the group consisting of: These materials may be used alone or in combination of two or more.
- glass can also be used as the material for the first member. This is considered to be due to the action of ions on the surface of the glass.
- FIG. 2 shows a schematic diagram when the first member has a conductive thin film on the surface of the substrate.
- FIG. 2 is a schematic cross-sectional view of the boundary surface of the first member, the surface layer, and the resin portion in the insert molded product.
- the 1st member 2 has the electroconductive thin film 2b on the surface of the base
- the insert molded product in FIG. 2 has a surface layer 3 on the thin film 2b of the first member 2, and further has a resin portion 4 thereon.

- the metal plating plating of a metal selected from noble metals such as gold, platinum and palladium, nickel, titanium, chromium, nickel titanium, nickel chromium, nickel tin, nickel tin cobalt, and stainless steel can be used.
- a more preferable conductive thin film is gold plating. Since gold has high transmission efficiency, it is suitably used in parts related to electrical signals such as electrical signal terminals. Moreover, since gold has high durability, it has the advantage that it is difficult to rust and has high chemical resistance. Inert metal plating such as gold plating has the property that it can be easily peeled off even if a treatment layer is formed on the surface thereof, so that gold plating is not conventionally used in parts that require watertightness. However, according to the present invention, by forming the surface layer on the gold plating and further forming the resin portion thereon, the adhesion between the gold plating and the surface layer is not lowered, and high water tightness is maintained. Therefore, gold plating can be used.
- the surface layer is a thin layer having conductivity.
- the thin film having conductivity include a thin film formed from a material having conductivity, a thin film having a conductive structure such as a porous structure, and a thin film having conductivity due to extremely thin film pressure.
- the surface layer is preferably a thin film made of a porous material or a thin film made of a hybrid material of a porous material and an organic compound. Since the surface layer has conductivity, it does not hinder the conductivity between the first member and the external member.
- the surface layer may be formed on the entire surface of the first member, or may be formed on a part of the surface.
- the surface layer may be a single layer or a multilayer of two or more layers.
- a compound of an element selected from Si, Ti, Al, Zr, Zn, Cr, Ni, Fe, Mo, B, Be, In, and Sn can be used.
- the compound is an oxide.
- These compounds may be used alone or in admixture of two or more.
- a more preferable surface layer material is a silicon compound.
- the silicon compound include silicon dioxide, silicon monoxide, and silicon hydroxide.
- the surface layer is a multilayer, it is preferable to include a layer formed of at least one compound selected from a titanium compound, an aluminum compound and a zirconium compound.
- the film thickness of the surface layer is preferably 1 nm or more, and preferably 50 mm or less. More preferably, it is 1000 nm or less, and particularly preferably 100 nm or less. If the film thickness of the surface layer is too large, it can cause cohesive failure.
- the preferred density of the surface layer depends on the material.
- the preferred density d20 of the surface layer when the following materials are used is exemplified below.
- Silicon dioxide 1.1-2.2 g / cm 3 Titanium oxide: 1.9 to 4.3 g / cm 3
- Nickel oxide 3.3 to 6.7 g / cm 3 If the density is too low, the strength decreases, so the above range is preferable.
- the surface roughness Ra of the surface layer is preferably in the range of 0.5 to 25 ⁇ m. If the surface roughness is too small, the anchor effect cannot be expected at all, which adversely affects the adhesion. On the other hand, if it is too large, the number of defect sites at the interface between the surface layer and the resin portion increases, making it difficult to obtain stable adhesion.
- the resin part is formed on at least a part of the surface layer formed on the surface of the first member, and is in close contact with the surface layer.
- the shape of the resin portion may be any shape according to the intended molded product.
- the resin part is preferably formed of a highly durable polymer material.
- thermoplastic resin, rubber and elastomer, and thermosetting resin can be used as the material of the resin portion.
- thermoplastic resins examples include PEI, LCP, polyphenylsulfone, PPO, polyethylene resin, polypropylene resin, polymethylpentene resin, polyester resin, polycarbonate resin, polyethersulfone resin, acrylic resin, polyimide resin, polysulfone resin, and polystyrene resin.
- Polyamide resin Polyphenylene sulfide resin, ethylene-tetrafluoroethylene copolymer, polyvinyl fluoride resin, tetrafluoroethylene-perfluoroether copolymer, tetrafluoroethylene-hexafluoropropylene copolymer, polytetrafluoroethylene resin, Selected from polyvinylidene fluoride resin, polytrifluorochloroethylene resin, aromatic polyketone, and ethylene-trifluorochloroethylene copolymer That the resin can be used.
- aromatic polyketones polyetheretherketone resin (PEEK) is preferable because it can be injection-molded and has excellent durability, and is particularly preferably used in an insert-molded product used for an endoscope.
- rubbers and elastomers examples include polyurethane, silicone rubber, fluorine rubber, natural rubber, neoprene rubber, chloroprene rubber, urethane rubber, acrylic rubber, olefin rubber, styrene-butadiene rubber, acrylonitrile-butadiene rubber, ethylene-propylene rubber, ethylene- A resin selected from propylene-diene rubber, butadiene rubber, butyl rubber, styrene-based thermoplastic elastomer, and urethane-based thermoplastic elastomer can be used.
- thermosetting resin for example, a resin selected from an epoxy resin, a phenol resin, a cyanate resin, a urea resin, and a guanamine resin can be used.
- the above resin part materials may be used alone or in admixture of two or more.
- the resin portion since the surface layer exists between the first member and the resin portion, the resin portion easily penetrates into fine irregularities on the surface of the first member. Due to the anchor effect, the first member and the resin portion are firmly adhered. Therefore, it is possible to maintain high water tightness. Moreover, compared with the molded article using the conventional adhesive agent, durability, such as chemical resistance and heat resistance, can be improved. Therefore, for example, even if the endoscope is cleaned and sterilized using an autoclave using acid and chemical substances and high-temperature and high-pressure steam, high water-tightness can be maintained for a long time.
- the insert molded product according to the present embodiment has high chemical resistance and heat resistance, and is therefore suitably used as a part for an endoscope. Moreover, since the molded article which has the outstanding water-tightness and durability can be simply manufactured by insert molding, it is used suitably also as a component of various articles

- the electric signal terminal 12 includes an electric cable 15 at one end.
- the presence of the surface layer on the electric signal terminal 12 maintains the water tightness between the electric signal terminal 12 and the resin portion 14 over a long period of time. Therefore, it can be used as an electrical signal connector for an endoscope.
- the resistance of the watertight portion depends on the resistance of the resin material, not the adhesive, the durability of the watertight portion can be further improved by using a highly resistant resin material.
- it can be manufactured by insert molding, there is no need to seal around the electrical contacts with an adhesive. Therefore, the cost of parts can be reduced.

図4は、レバー20の模式図である。レバー20は、ステンレスやチタンなど難錆性の金属部品を芯材22として用い、内側の面を除いた周囲を樹脂24で覆われている。芯材22の表面には表面層が形成されている。これにより、金属と樹脂の境界面の密着性を得ることができる。よって、レバー20のように金属製の芯材の一部が露出した成形品においても、境界面から水や菌などが浸入することを防ぐことができる。このような水密性は、内視鏡の洗浄消毒滅菌のプロセスによっても容易に破壊されず、密着性を保つことができる。

図6に、内視鏡先端構造部品40の模式図を示す。この内視鏡先端構造部品40は、先端の光学部品としてガラス部品42を使用している。ガラス部品42を芯材として用い、その周囲に樹脂部44が成形されている。ガラス部品42の表面には表面層が形成されている。これにより、ガラス部品42と樹脂部44とは強固に結合しているため、その境界面における水密性が維持される。よって、境界面から水や菌などが浸入することを防ぐことができる。このような水密性は、内視鏡の洗浄消毒滅菌のプロセスによっても容易に破壊されず、密着性を保つことができる。部品同士の境界が菌で汚染されることを防げるために、安全な内視鏡を提供することができる。
