PROBLEM TO BE SOLVED: To provide a coated body which is provided with a coating film formed with an acrylic resin-based coating, and the calorific value of the coating film on burning is reduced.SOLUTION: A coated body 1 includes a ceramic-based substrate 11 and a coating layer 13 formed with an acrylic resin-based coating, and the coating layer 13 contains 10-20 mass% of powder of a vinylidene chloride resin.

Description

本発明は、窯業系基材に塗膜を形成した塗装体に関するものである。   The present invention relates to a coated body having a coating film formed on a ceramic base material.

従来、窯業系基材に塗膜を形成して得られる塗装体は、外壁材として、広く利用されている。外壁材には、その下地を隠蔽するため、着色塗装が施される。また、着色塗料として、耐久性に優れ且つ外観意匠性の向上に寄与可能なアクリルエマルション樹脂系のエナメル塗料が用いられる（例えば、特許文献１参照）。   Conventionally, a coated body obtained by forming a coating film on a ceramic base material has been widely used as an outer wall material. The outer wall material is colored to conceal the foundation. As the colored paint, an acrylic emulsion resin-based enamel paint that is excellent in durability and can contribute to improvement in appearance design is used (for example, see Patent Document 1).

特開２００８−２４６３４０号公報JP 2008-246340 A

防災意識の高まりにより、外壁材の耐火性・防火性のさらなる向上が求められている。   Due to heightened awareness of disaster prevention, further improvements in the fire resistance and fire resistance of outer wall materials are required.

また、外壁材の耐火性・防火性は、窯業系基材自体が難燃性であることから、窯業系基材に形成される塗膜の組成によって左右される。   In addition, the fire resistance and fire resistance of the outer wall material depend on the composition of the coating film formed on the ceramic base material because the ceramic base material itself is flame retardant.

しかしながら、塗膜を形成するためにアクリルエマルション樹脂系のエナメル塗料を用いると、アクリルエマルション樹脂系のエナメル塗料が有機系の塗料であるために、塗膜の燃焼時の発熱量が増加してしまい、耐火性・防火性を阻害するという問題がある。   However, when an acrylic emulsion resin-based enamel coating is used to form a coating film, the amount of heat generated when the coating film burns increases because the acrylic emulsion resin-based enamel coating is an organic coating. There is a problem of inhibiting fire resistance and fire resistance.

本発明は、上記の点に鑑みてなされたものであり、アクリル樹脂系塗料から形成された塗膜を備え、且つ、この塗膜の燃焼時の発熱量が低減された塗装体を提供することを目的とするものである。   The present invention has been made in view of the above points, and provides a coated body that includes a coating film formed from an acrylic resin-based paint and that has a reduced amount of heat generated when the coating film burns. It is intended.

本発明に係る塗装体は、窯業系基材と、アクリル樹脂系の塗料から形成される塗料層とを備える塗装体であって、前記塗料層が１０〜２０質量％の範囲内の塩化ビニリデン樹脂粉を含有することを特徴とするものである。   The coated body according to the present invention is a coated body comprising a ceramic base material and a paint layer formed from an acrylic resin-based paint, wherein the paint layer has a vinylidene chloride resin content in the range of 10 to 20% by mass. It is characterized by containing powder.

本発明にあっては、前記塩化ビニリデン樹脂粉の平均粒径が、２〜３０μｍの範囲内であることが好ましい。   In this invention, it is preferable that the average particle diameter of the said vinylidene chloride resin powder exists in the range of 2-30 micrometers.

本発明では、塗料層の燃焼時に、塗料層中の塩化ビニリデン樹脂粉から不活性ガスが発生するため、塗料層の燃焼が抑制され、発熱量も抑制される。   In the present invention, since an inert gas is generated from the vinylidene chloride resin powder in the paint layer during combustion of the paint layer, combustion of the paint layer is suppressed and the amount of generated heat is also suppressed.

本発明の実施の形態を示す概略の断面図である。1 is a schematic cross-sectional view showing an embodiment of the present invention. 本発明の実施の形態の一変形例である。It is a modification of embodiment of this invention.

本発明に係る塗装体１は、窯業系基材１１と、アクリル樹脂系の塗料から形成される塗料層１３とを備える。   The coated body 1 according to the present invention includes a ceramic base material 11 and a paint layer 13 formed from an acrylic resin-based paint.

本発明では、塗料層１３がアクリル樹脂系の塗料から形成されるため、耐久性、外観に優れる。   In the present invention, since the coating layer 13 is formed from an acrylic resin-based coating, it is excellent in durability and appearance.

本発明では、塗料層１３が１０〜２０質量％の範囲内の塩化ビニリデン樹脂粉を含有するため、塗料層１３の燃焼時に、塩化ビニリデンの樹脂から不活性ガスが発生することで、塗料層１３の燃焼が抑制され、発熱量も抑制される。   In the present invention, since the paint layer 13 contains vinylidene chloride resin powder in the range of 10 to 20% by mass, the paint layer 13 is generated by generating an inert gas from the vinylidene chloride resin when the paint layer 13 is burned. Combustion is suppressed, and the amount of heat generated is also suppressed.

以下、本発明を実施するための形態を説明する。   Hereinafter, modes for carrying out the present invention will be described.

本実施形態の塗装体１は、図１に示すように、窯業系基材１１と塗料層１３とを備える。   As shown in FIG. 1, the coated body 1 of the present embodiment includes a ceramic base material 11 and a paint layer 13.

また、塗装体１は、塗料層１３以外の一以上の層を更に備えてもよい。本実施形態では、窯業系基材１１と塗料層１３との間に、下塗層１２が形成される。勿論、窯業系基材１１の上に直接、塗料層１３が積層してもよい。   The coated body 1 may further include one or more layers other than the paint layer 13. In this embodiment, an undercoat layer 12 is formed between the ceramic base material 11 and the paint layer 13. Of course, the paint layer 13 may be laminated directly on the ceramic base 11.

窯業系基材１１は、例えば、無機質硬化体の原料となる水硬性膠着材に対して、無機充填剤、繊維質材料等を配合し、これを成形後、養生硬化させることで得られる。水硬性膠着材は、特に限定されるものではないが、例えば、ポルトランドセメント、高炉セメント、高炉スラグ、ケイ酸カルシウム及び石膏からなる群から選択される一種以上の材料を含有することができる。また、無機充填剤は、例えば、フライアッシュ、ミクロシリカ及び珪砂からなる群から選択される一種以上の材料を含有することができる。また、繊維質材料は、例えば、パルプ、合成繊維等の無機繊維、スチールファイバー等の金属繊維から選択される一種以上の材料を含有することができる。また、成形方法は、例えば、押出成形、注型成形、抄造成形、プレス成形等から選択される。窯業系基材１１の成形後には、必要に応じてオートクレーブ養生、蒸気養生、常温養生等を行う。   The ceramic base material 11 is obtained, for example, by blending an inorganic filler, a fibrous material, or the like with a hydraulic glue used as a raw material for an inorganic hardened body, and curing and curing it after molding. The hydraulic glue is not particularly limited, but can contain, for example, one or more materials selected from the group consisting of Portland cement, blast furnace cement, blast furnace slag, calcium silicate, and gypsum. The inorganic filler can contain, for example, one or more materials selected from the group consisting of fly ash, microsilica, and silica sand. The fibrous material can contain, for example, one or more materials selected from inorganic fibers such as pulp and synthetic fibers, and metal fibers such as steel fibers. The molding method is selected from, for example, extrusion molding, cast molding, papermaking molding, press molding, and the like. After the ceramic base material 11 is molded, autoclave curing, steam curing, room temperature curing, or the like is performed as necessary.

下塗層１２は、窯業系基材１１の表面上に形成され、窯業系基材１１の表面上に凹凸等がある場合の目止め及び窯業系基材１１と塗料層１３との密着性の確保を為す。   The undercoat layer 12 is formed on the surface of the ceramic base material 11, and has an adhesiveness between the ceramic base material 11 and the coating layer 13 when there are irregularities on the surface of the ceramic base material 11. Make sure.

下塗層１２は、下塗塗料から形成される。下塗塗料は、アクリル樹脂系の塗料であることが好ましい。下塗塗料として、例えば、低分子量の樹脂及び小粒径のエマルション等を含有する浸透性タイプの塗料を用いることができる。下塗塗料は、顔料を含有してもよい。顔料は、例えば、酸化チタン、酸化鉄系顔料、カーボンブラック及び炭酸カルシウムからなる群から選択される一種以上の材料を含有することができる。下塗塗料は、例えば、アクリルエマルション樹脂に対して、顔料、その他の添加剤、水等を加えて撹拌分散することで調製される。   The undercoat layer 12 is formed from an undercoat paint. The undercoat paint is preferably an acrylic resin-based paint. As the undercoat paint, for example, a permeable type paint containing a low molecular weight resin and a small particle size emulsion can be used. The undercoat paint may contain a pigment. The pigment can contain, for example, one or more materials selected from the group consisting of titanium oxide, iron oxide pigments, carbon black, and calcium carbonate. The undercoat paint is prepared, for example, by adding a pigment, other additives, water, and the like to an acrylic emulsion resin and stirring and dispersing it.

下塗層１２は、例えば、窯業系基材１１の表面上に下塗塗料を塗布後、焼付乾燥して形成される。下塗塗料の塗布方法は、例えば、スプレーガン、ロールコーター、フローコーター、カーテンコーター等から選択される。このとき、下塗塗料の塗布量は、５０〜１７０ｇ／ｍ２の範囲内であることが好ましい。また、下塗塗料の焼付乾燥は、８０〜１２０℃で１〜３分間の範囲内で行うことが好ましい。 The undercoat layer 12 is formed, for example, by applying an undercoat paint on the surface of the ceramic base 11 and baking and drying it. The application method of the undercoat paint is selected from, for example, a spray gun, a roll coater, a flow coater, a curtain coater and the like. At this time, the coating amount of the undercoat paint is preferably in the range of 50 to 170 g / m 2 . Moreover, it is preferable to carry out baking and drying of the undercoat paint within a range of 1 to 3 minutes at 80 to 120 ° C.

塗料層１３は、下塗層１２の表面上にアクリル樹脂系の塗料（以下、上塗塗料という）を塗布して形成される。特に、上塗塗料は、下地の隠蔽力が高く、耐久性に優れ、種類豊富な色揃えを有し、外観意匠性向上に寄与可能なアクリル樹脂系のエナメル塗料であることが好ましい。   The paint layer 13 is formed by applying an acrylic resin-based paint (hereinafter referred to as top coat paint) on the surface of the undercoat layer 12. In particular, the top coating material is preferably an acrylic resin-based enamel coating material that has a high base hiding power, excellent durability, has a wide variety of colors, and can contribute to an improvement in appearance design.

上塗塗料は、エナメル塗料である場合、顔料を含有してもよい。顔料は、例えば、酸化チタン、酸化鉄系顔料、カーボンブラック及び硫酸バリウムからなる群から選択される一種以上の材料を含有することができる。   When the top coat is an enamel paint, it may contain a pigment. The pigment can contain, for example, one or more materials selected from the group consisting of titanium oxide, iron oxide pigments, carbon black, and barium sulfate.

上塗塗料は、塩化ビニリデン樹脂粉を含有する。本願実施形態では、上塗塗料中の固形成分に対する塩化ビニリデン樹脂粉の割合は、１０〜２０質量％の範囲内である。そのため、例えば、上塗塗料が塩化ビニリデン樹脂粉を５〜１０質量％の範囲内の割合で含有する。   The top coat contains vinylidene chloride resin powder. In this embodiment, the ratio of the vinylidene chloride resin powder with respect to the solid component in top coat is in the range of 10-20 mass%. Therefore, for example, the top coating material contains vinylidene chloride resin powder in a proportion within the range of 5 to 10% by mass.

塩化ビニリデン樹脂粉は、例えば、塩化ビニル樹脂を原料として得られる。塩化ビニル樹脂は再生品であってもよい。例えば、塩化ビニル樹脂系の塗料を用いた塗装工程で発生する廃塗料から回収された塩化ビニル樹脂が用いられてもよい。   The vinylidene chloride resin powder is obtained using, for example, a vinyl chloride resin as a raw material. The vinyl chloride resin may be a recycled product. For example, a vinyl chloride resin recovered from waste paint generated in a painting process using a vinyl chloride resin-based paint may be used.

本実施形態では、塩化ビニリデン樹脂粉の平均粒径が２〜３０μｍの範囲内であることが好ましい。塩化ビニリデン樹脂粉の平均粒径が２μｍ以上であると、上塗塗料の原料と塩化ビニリデン樹脂粉とを容易に撹拌分散することができる。また、平均粒径が３０μｍ以下であると、上塗塗料から塗料層１３を形成した際の外観が向上する。   In this embodiment, it is preferable that the average particle diameter of vinylidene chloride resin powder exists in the range of 2-30 micrometers. When the average particle diameter of the vinylidene chloride resin powder is 2 μm or more, the raw material for the top coating material and the vinylidene chloride resin powder can be easily stirred and dispersed. Further, when the average particle size is 30 μm or less, the appearance when the paint layer 13 is formed from the top coat is improved.

本実施形態では、上塗塗料は、例えば、アクリルエマルション樹脂に対して、顔料、塩化ビニリデン樹脂、その他の添加剤、水等を加えて撹拌分散することで調製される。   In the present embodiment, the top coat is prepared by, for example, adding a pigment, vinylidene chloride resin, other additives, water, and the like to an acrylic emulsion resin and stirring and dispersing it.

塗料層１３は、例えば、下塗層１２の表面上に、上塗塗料を塗布後、焼付乾燥して形成される。上塗塗料の塗布方法は、例えば、スプレーガン、ロールコーター、フローコーター、カーテンコーターからなる群から選択される。上塗塗料の塗布量は、７６〜１４０ｇ／ｍ２の範囲内であることが好ましい。塗布した上塗塗料の焼付乾燥は、例えば、ジェット乾燥機を用いて、８０〜１２０℃で１〜３分間の範囲内で行うことが好ましい。 The coating layer 13 is formed by, for example, applying a top coating on the surface of the undercoat layer 12 and baking and drying. The method of applying the top coating material is selected from the group consisting of, for example, a spray gun, a roll coater, a flow coater, and a curtain coater. The coating amount of the overcoat coating composition is preferably in the range of 76~140g / m 2. The applied top coating is preferably baked and dried at 80 to 120 ° C. for 1 to 3 minutes using, for example, a jet dryer.

本実施形態では、塗料層１３が、１０〜２０質量％の範囲内の塩化ビニリデン樹脂粉を含有する。塩化ビニリデン樹脂粉の含有量が１０質量％以上であるため、塗料層１３の燃焼時に、塩化ビニリデン樹脂粉から、特に不活性ガスが発生するため、塗料層１３の燃焼が抑制され、発熱量も抑制される。含有量が２０質量％以下であるため、下塗層１２との密着性を確保することができる。   In the present embodiment, the coating layer 13 contains vinylidene chloride resin powder in the range of 10 to 20% by mass. Since the content of the vinylidene chloride resin powder is 10% by mass or more, an inert gas is generated particularly from the vinylidene chloride resin powder when the coating layer 13 is burned, so that the burning of the coating layer 13 is suppressed and the calorific value is also increased. It is suppressed. Since content is 20 mass% or less, adhesiveness with the undercoat layer 12 is securable.

本実施形態の塗装体１は、窯業系基材１１と塗料層１３とを備えるものであるが、塗料層１３の上に、任意の層を設けてもよい。例えば、塗装体１の耐候性向上のため、塗料層１３の上にクリヤー層１４を形成することができる。図２に本実施形態の一変形例を示す。本実施形態に係る塗装体１はクリヤー層１４を備える。クリヤー層１４は、例えば、紫外線カット剤を添加したアクリル樹脂塗料から形成される。紫外線カット剤としては、例えば、ベンゾトリアゾール系紫外線吸収剤を用いることができる。   The coated body 1 of the present embodiment includes the ceramic base 11 and the paint layer 13, but an arbitrary layer may be provided on the paint layer 13. For example, the clear layer 14 can be formed on the paint layer 13 in order to improve the weather resistance of the coated body 1. FIG. 2 shows a modification of the present embodiment. The coated body 1 according to this embodiment includes a clear layer 14. The clear layer 14 is formed of, for example, an acrylic resin paint to which an ultraviolet cut agent is added. As the ultraviolet blocking agent, for example, a benzotriazole ultraviolet absorber can be used.
