Description

本発明は、表面シートにより表面層を形成したＦＲＰ成形品及び洗い場床パンに関するものである。   The present invention relates to an FRP molded product having a surface layer formed of a surface sheet and a washing floor floor pan.

従来からＳＭＣからなる基材層と、繊維補強材と、不織布に熱硬化性樹脂を含浸させた表面シートとを積層一体成形したＦＲＰ成形品が特許文献１により知られている。   Conventionally, Patent Document 1 discloses an FRP molded product in which a base material layer made of SMC, a fiber reinforcing material, and a surface sheet in which a nonwoven fabric is impregnated with a thermosetting resin are integrally laminated.

しかしながら、上記特許文献１に示された従来例にあっては、繊維補強材を、ＳＭＣからなる基材層と、熱硬化性樹脂を含浸させた表面シートとの間に介在させて全体を加熱加圧することで一体成形するものであるから、加熱加圧する際に基材層を形成するためのＳＭＣの含浸樹脂が繊維補強材内に入り込み、更に、繊維補強材を通過して表面シート部分に圧入し、表面シートの表面に部分的にＳＭＣ中の含浸樹脂が突き抜けて露出するおそれがある。このようにして成形されるＦＲＰ成形品の表面層は表面シートにより形成されるのでＦＲＰ成形品の表面の特性は表面シートにより特定される特性となる。しかしながら、上記のように表面シートに部分的にＳＭＣ中の含浸樹脂が突き抜けて露出するため、ＦＲＰ成形品の表面の一部のＳＭＣ中の含浸樹脂が突き抜けて露出する部分においては、表面シートにより特定される特性と異なり、表面特性が均一にならないという問題がある。   However, in the conventional example shown in Patent Document 1, the whole is heated by interposing a fiber reinforcing material between a base material layer made of SMC and a surface sheet impregnated with a thermosetting resin. Since it is integrally formed by pressurization, the SMC impregnation resin for forming the base material layer enters the fiber reinforcement when heated and pressurized, and further passes through the fiber reinforcement to the surface sheet portion. There is a possibility that the impregnated resin in the SMC may partially penetrate and be exposed on the surface of the topsheet. Since the surface layer of the FRP molded product formed in this way is formed by the surface sheet, the surface characteristics of the FRP molded product become the characteristics specified by the surface sheet. However, since the impregnated resin in the SMC partially penetrates and is exposed on the top sheet as described above, in the part where the impregnated resin in the SMC part of the surface of the FRP molded product penetrates and is exposed, Unlike the specified characteristics, there is a problem that the surface characteristics are not uniform.

また、上記特許文献１に示されたＦＲＰ成形品は、表面に微小なクラックや凹凸を形成する物理的処理やプラズマ処理やコロナ放電処理等による化学的処理により親水化処理を行うことで、表面の排水性及び乾燥性を良好にするようにしているが、この従来例にあっては、表面に物理的処理や化学的処理を施すことで親水化処理を行うものであるから、親水化処理のための特別な工程が必要となり、コストが高くなる。
特開２００２−３４７１８２号公報 Further, the FRP molded article shown in Patent Document 1 is subjected to a hydrophilic treatment by a physical treatment that forms minute cracks or irregularities on the surface, or a chemical treatment such as plasma treatment or corona discharge treatment. However, in this conventional example, the hydrophilic treatment is performed by applying physical treatment or chemical treatment to the surface. A special process is required for this, and the cost increases.
JP 2002-347182 A

本発明は上記の従来の問題点に鑑みて発明したものであって、ＳＭＣの含浸樹脂が表面層に突き抜けて露出することがなく、表面層を、表面シートのみによる均質な特性にすることができ、また、物理的処理や化学的処理による親水化処理を行うことなく簡単な構成で表面の親水性を持たせることができて表面の排水性や乾燥性に優れたＦＲＰ成形品及び洗い場床パンを提供することを課題とするものである。   The present invention has been invented in view of the above-mentioned conventional problems, and the SMC impregnated resin does not penetrate through the surface layer and is exposed, and the surface layer is made to have uniform characteristics only by the surface sheet. FRP molded products and washroom floors that can be made hydrophilic with a simple structure and have excellent surface drainage and drying properties without performing hydrophilic treatment by physical treatment or chemical treatment. The challenge is to provide bread.

上記課題を解決するために本発明に係るＦＲＰ成形品は、ＳＭＣからなる基材層１と、不織布に樹脂を含浸させた中間シートよりなる中間層２と、不織布に樹脂を含浸させた表面シートよりなる表面層３とを上下に積層一体成形したＦＲＰ成形品であって、上記ＳＭＣと表面シートとの間に介在される中間シートが上記ＳＭＣや表面シートよりも速硬性のものであることを特徴とするものである。   In order to solve the above problems, an FRP molded product according to the present invention includes a base material layer 1 made of SMC, an intermediate layer 2 made of an intermediate sheet in which a nonwoven fabric is impregnated with a resin, and a surface sheet in which a nonwoven fabric is impregnated with a resin. FRP molded product in which the surface layer 3 is integrally laminated up and down, and the intermediate sheet interposed between the SMC and the surface sheet is faster-hardening than the SMC and the surface sheet. It is a feature.

このように表面シートを設けることで、表面をＳＭＣとは別材料の層にできるのみならず、表面をＳＭＣの材料とは別の層とするものにおいて、中間層２を形成するための中間シートがＳＭＣや表面シートよりも速硬性であるので、厚みの厚い基材層１を形成するためのＳＭＣの含浸樹脂が速硬性の中間シートにより遮られて表面シート側に突き抜けて露出することがなく、この結果、ＳＭＣ成形品４の表面は表面シートのみによる均質な特性の表面層３とすることができる。   By providing the surface sheet in this way, not only the surface can be made of a layer different from the material of SMC, but also an intermediate sheet for forming the intermediate layer 2 when the surface is a layer different from the material of SMC. Is harder than SMC and the surface sheet, so that the impregnating resin of SMC for forming the thick base material layer 1 is blocked by the fast-curing intermediate sheet and penetrates to the surface sheet side and is not exposed. As a result, the surface of the SMC molded product 4 can be a surface layer 3 having a uniform characteristic using only the surface sheet.

また、表面シート、中間シートの含浸樹脂がＳＭＣの含浸樹脂であるポリエステル樹脂よりも親水性の優れたアクリル樹脂又はポリ酢酸ビニル樹脂又はポリウレタン樹脂で構成してあることが好ましい。   Moreover, it is preferable that the impregnating resin of the top sheet and the intermediate sheet is made of an acrylic resin, a polyvinyl acetate resin, or a polyurethane resin having a hydrophilicity superior to that of the polyester resin that is an SMC impregnating resin.

このような構成とすることで、表面層３が親水性を有した表面シートのみにより構成され、表面層３にＳＭＣの含浸樹脂が突き抜けて露出することによる親水性の低下を防ぐことができる。   By setting it as such a structure, the surface layer 3 is comprised only by the surface sheet which has hydrophilic property, and the hydrophilicity fall by the impregnation resin of SMC penetrating and exposing to the surface layer 3 can be prevented.

また、表面シート、中間シートの不織布がガラス、あるいはガラスとポリエステルが混紗されたものであることが好ましい。   Moreover, it is preferable that the nonwoven fabric of a surface sheet and an intermediate | middle sheet | seat is what mixed glass or glass and polyester.

このような構成とすることで、成形後に表面層３、中間層２が透明になり、ＳＭＣ色が透過してＳＭＣ色を生かすことができる。   With such a configuration, the surface layer 3 and the intermediate layer 2 become transparent after molding, and the SMC color can be transmitted and the SMC color can be utilized.

また、上記のようなＦＲＰ成形品４が洗い場床パン５であることが好ましい。   Moreover, it is preferable that the FRP molded product 4 as described above is the washroom floor pan 5.

本発明は、ＳＭＣの含浸樹脂が表面層に突き抜けて露出することがなく、表面層を、表面シートのみによる均質な特性にすることができ、表面の特性のばらつきが無い。   In the present invention, the impregnated resin of SMC does not penetrate through the surface layer and is exposed, and the surface layer can be made to have uniform characteristics only by the surface sheet, and there is no variation in surface characteristics.

また、表面シート、中間シートの含浸樹脂を親水性のあるアクリル樹脂又はポリ酢酸ビニル樹脂又はポリウレタン樹脂で構成することで、従来のように物理的処理や化学的処理を施すことで親水化処理を行うことなく簡単な構成で表面の親水性を持たせることができて表面の排水性や乾燥性に優れている。   Also, by making the impregnating resin of the top sheet and intermediate sheet with hydrophilic acrylic resin, polyvinyl acetate resin or polyurethane resin, the hydrophilic treatment can be performed by applying physical treatment or chemical treatment as before. It is possible to give the surface hydrophilicity with a simple configuration without performing it, and the surface has excellent drainage and drying properties.

以下、本発明を添付図面に示す実施形態に基いて説明する。   Hereinafter, the present invention will be described based on embodiments shown in the accompanying drawings.

本発明のＳＭＣ成形品４は、図１に示すように、ＳＭＣからなる基材層１と、その上の不織布に樹脂を含浸させた中間シートよりなる中間層２と、その上の不織布に樹脂を含浸させた表面シートよりなる表面層３との３層構造となっており、ＳＭＣ、中間シート、表面シートとを同時成形することで３層を上下に積層一体成形して構成してある。   As shown in FIG. 1, the SMC molded product 4 of the present invention includes a base material layer 1 made of SMC, an intermediate layer 2 made of an intermediate sheet obtained by impregnating a non-woven fabric thereon with a resin, and a non-woven fabric thereon. The surface layer 3 is made of a surface sheet impregnated with SMC, and the SMC, the intermediate sheet, and the surface sheet are formed at the same time, and the three layers are stacked and integrally formed vertically.

基材層１を形成するためのＳＭＣはガラス繊維マットに樹脂を含浸させたもので、含浸樹脂として不飽和ポリエステル樹脂を挙げることができる。   The SMC for forming the base material layer 1 is obtained by impregnating a glass fiber mat with a resin, and examples of the impregnating resin include unsaturated polyester resins.

中間層２を形成するための中間シート、表面層３を形成するための表面シートはいずれも、不織布に樹脂を含浸したもので、この中間シート、表面シートに含浸する樹脂としてはＳＭＣの含浸樹脂とは異なる樹脂、つまり、ＳＭＣの含浸樹脂であるポリエステル樹脂よりも親水性の優れたアクリル樹脂又はポリ酢酸ビニル樹脂又はポリウレタン樹脂が用いられる。また、中間シートはＳＭＣ、表面シートよりも速硬性のものが用いられる。中間シートを速硬性とするには例えば反応を速めるための触媒を添加する。   Both the intermediate sheet for forming the intermediate layer 2 and the surface sheet for forming the surface layer 3 are obtained by impregnating a nonwoven fabric with a resin. The resin impregnated in the intermediate sheet and the surface sheet is an SMC impregnated resin. An acrylic resin, a polyvinyl acetate resin, or a polyurethane resin that is more hydrophilic than a polyester resin that is an impregnation resin of SMC, that is, a resin different from that of SMC. Further, as the intermediate sheet, an SMC or a sheet having a faster hardness than the surface sheet is used. In order to make the intermediate sheet fast-curing, for example, a catalyst for accelerating the reaction is added.

上記のような硬化前のＳＭＣ、中間シート、表面シートを用いて成形金型により一体に同時成形してＦＲＰ成形品を成形するのであるが、この場合、下金型に表面シート、中間シート、ＳＭＣの順で載置するか、又は、下金型にＳＭＣ、中間シート、表面シートの順で載置し（つまり、意匠側となる方の金型側に表面シートが位置し、裏面側となる金型側にＳＭＣが位置するようにする）、その後、上金型を移動して加熱加圧成形することで、ＳＭＣよりなる基材層１、中間シートよりなる中間層２、表面シートよりなる表面層３が積層一体化される。   The SRP before curing as described above, an intermediate sheet, and a surface sheet are integrally molded simultaneously by a molding die to form an FRP molded product. In this case, a surface sheet, an intermediate sheet, Place in the order of SMC, or place in the lower mold in the order of SMC, intermediate sheet, surface sheet (that is, the surface sheet is located on the mold side which is the design side, SMC is positioned on the mold side), and then the upper mold is moved and heated and pressed to form a base material layer 1 made of SMC, an intermediate layer 2 made of an intermediate sheet, and a surface sheet The resulting surface layer 3 is laminated and integrated.

ここで、中間シートがＳＭＣ、表面シートよりも速硬性のものであるため、上記加熱加圧成形の際、中間シートがＳＭＣや表面シートよりも速く硬化し、このため、加熱加圧により厚みの厚いＳＭＣの含浸樹脂が中間シートを突き抜けて、更に、表面シートの表面側（金型と接する面）に突き抜けるのが防止される。したがって、成形されたＦＲＰ成形品４においては、表面層３にＳＭＣの含浸樹脂が突き抜けて露出せず、表面層３は表面シートのみにより形成されることになり、表面シートとして親水性の優れたアクリル樹脂又はポリ酢酸ビニル樹脂又はポリウレタン樹脂を用いることで、優れた親水性を発揮できることになる。また、表面シートとしてアクリル樹脂を用いた場合は表面硬度も向上させることができる。   Here, since the intermediate sheet is faster-hardening than SMC and the surface sheet, the intermediate sheet is cured faster than SMC and the surface sheet during the heat and pressure molding. It is possible to prevent the thick SMC impregnating resin from penetrating the intermediate sheet and further penetrating to the surface side (surface in contact with the mold) of the surface sheet. Therefore, in the molded FRP molded product 4, the SMC impregnated resin does not penetrate through the surface layer 3 and is not exposed, and the surface layer 3 is formed only by the surface sheet, and has excellent hydrophilicity as the surface sheet. By using an acrylic resin, a polyvinyl acetate resin, or a polyurethane resin, excellent hydrophilicity can be exhibited. Moreover, when an acrylic resin is used as the surface sheet, the surface hardness can also be improved.

上記表面シート、中間シートの不織布としてはガラス、あるいはガラスとポリエステルが混紗されたものを用いることが好ましい。   It is preferable to use glass or a mixture of glass and polyester as the nonwoven fabric for the top sheet and intermediate sheet.

このように、表面シート、中間シートの不織布としてはガラス、あるいはガラスとポリエステルが混紗されたものを用いると、表面シート、中間シートが成形後に透明になり、ＳＭＣ色が透過してＳＭＣ色を生かすことができる。   As described above, when the surface sheet and the nonwoven sheet of the intermediate sheet are made of glass or a mixture of glass and polyester, the surface sheet and the intermediate sheet become transparent after molding, and the SMC color is transmitted and the SMC color is changed. You can save it.

上記のようなＦＲＰ成形品４としては洗い場床パン５、あるいはカウンター等各種の水廻りで使用される商品であり、表面が親水性であるため、通常のＳＭＣ成形品に比べて、同じ残水量でも残水の表面積が大きくなるので、排水性が良くなると共に濡れてから乾燥するまでの時間が短くなり、排水性、乾燥性が優れたものとなる。また、湿気が少なくなるので、防カビ効果もある。   The FRP molded product 4 as described above is a product used in various places such as a washing floor pan 5 or a counter, and since the surface is hydrophilic, the amount of residual water is the same as that of a normal SMC molded product. However, since the surface area of the residual water is increased, the drainage is improved and the time from wet to dry is shortened, and the drainage and drying are excellent. Further, since the moisture is reduced, there is also an antifungal effect.
