Description
本発明は、動植物油等の油分の浸透を抑制する耐油紙および耐油紙の製造方法に関するものである。 The present invention relates to an oil-resistant paper that suppresses permeation of oil such as animal and vegetable oils and a method for producing the oil-resistant paper.
従来より耐油紙は、洗剤、菓子、乾燥食品等の包装容器用素材として広く使用されていた。その用途としては様々なものがあるが、耐油性を付与した板紙については菓子等の食品用の箱、とりわけ油脂分を大量に含むチョコレート菓子等の箱としてや、薄葉紙に耐油性を付与したものについてはファーストフードなどの揚げ物を包装する容器やデパート、コンビニエンスストアなどでのテイクアウト食材の包装容器等に多く使用されている。 Conventionally, oil-resistant paper has been widely used as a material for packaging containers such as detergents, confectionery, and dried foods. There are various uses, but for paperboard with oil resistance, it is used as a box for food such as confectionery, especially as a box for chocolate confectionery containing a large amount of oils and fats. Is often used for containers for packaging fried foods such as fast food, and for take-out food packaging containers in department stores and convenience stores.
紙に耐油性を付与する手段としては、優れた耐油性を有するフッ素樹脂系の耐油剤が従来使用されており、例えば、紙、板紙の表面にフッ素樹脂系耐油剤を塗工して耐油層を設けたクッキングシートまたは紙層間にフッ素樹脂系耐油剤層を設けた菓子箱用の耐油板紙等が存在した。しかし、フッ素樹脂系耐油剤を使用した紙は、100〜180℃の食品調理温度で加熱した場合、炭素数8〜10のフッ素系アルコール化合物等、長期に残留しやすい成分が発生することが確認されている。また、これらフッ素樹脂系耐油剤を使用した紙を使用後焼却した際には、パーフルオロオクタン酸やパーフルオロスルホン酸等のフッ素化合物が生成し、健康または環境に悪影響を及ぼすことが懸念されるため、フッ素樹脂系耐油剤を使用しない耐油紙が求められている。 As a means for imparting oil resistance to paper, a fluororesin-based oil-resistant agent having excellent oil resistance has been conventionally used. For example, by applying a fluororesin-based oil-resistant agent on the surface of paper or paperboard, an oil-resistant layer There existed a cooking sheet provided with an oil-resistant paperboard for a confectionery box provided with a fluororesin-based oilproofing agent layer between paper sheets. However, it is confirmed that papers using fluororesin-based oilproofing agents are likely to remain for a long time, such as fluorine-based alcohol compounds having 8 to 10 carbon atoms, when heated at a food cooking temperature of 100 to 180 ° C. Has been. In addition, when papers using these fluororesin-based oilproofing agents are incinerated after use, there is a concern that fluorine compounds such as perfluorooctanoic acid and perfluorosulfonic acid may be generated and adversely affect health or the environment. Therefore, there is a demand for oil-resistant paper that does not use a fluororesin-based oil resistant agent.
前記した熱分解するフッ素系薬品代替の耐油紙としては紙基材にアクリル樹脂系耐油剤を塗布したもの、ポリエチレンフィルム貼合紙、ポリエチレン樹脂を塗布したもの、シリコーン系、ワックス系耐油剤を使用したもの、熱を加えても不活性ガスを発生させないように製法が改良されたフッ素系樹脂を使用したもの等々の耐油紙ならびに該耐油紙の製造技術が開示されているが、それぞれ長所・短所があるため一部実用化されてはいるものの依然として、使用者からの改善要望は根強い。 As the above-mentioned oil-resistant paper as a substitute for fluorine-based chemicals that decompose thermally, paper base coated with acrylic resin-based oil-resistant agent, polyethylene film-bonded paper, polyethylene-coated resin, silicone-based, wax-based oil-resistant agent are used. Oil-resistant paper such as those using a fluorine-based resin whose production method has been improved so that inert gas is not generated even when heat is applied, and the technology for producing the oil-resistant paper are disclosed. Although it has been put into practical use, there is still a strong demand for improvement from users.
ところで、薬品の撥油性によって外部への油脂成分の滲出を防止するフッ素系樹脂を用いた耐油紙では必要耐油剤量が少量であるため、内部に添加、もしくはサイズプレスで該樹脂を表面に塗布させることが可能であった。 By the way, the oil-resistant paper using a fluorine resin that prevents the exudation of oil and fat components to the outside due to the oil repellency of chemicals requires a small amount of oil-resistant agent, so it is added inside or applied to the surface with a size press It was possible to make it.
一方、アクリル系樹脂エマルションの塗工により製造した耐油紙は、耐油層をピンホールなく成膜させて外部への油脂成分の滲出を防止することにより耐油性を発現させているため、フッ素系樹脂と比較すると、同等の耐油性を発現させるために必要な耐油剤量が多くなってしまうという問題がある。例えば、特許文献1〜3にはアクリル系樹脂をオフコーターもしくは印刷機を用いて基紙上に幾層にもわたり塗布する技術が開示されているが、いずれも幾層にもわたり塗布することにより耐油性は確保できるもののその手間の多さからコストが極端に高くなる。
また、特許文献4には耐油剤をエアーナイフコーターで単層のみ塗布する技術が開示されているが、エアーナイフコーターでの塗工の場合は、塗料濃度を比較的低く抑えなければならないため、乾燥負荷が増大し、生産効率が低下するため好ましくない。
On the other hand, oil-resistant paper produced by coating acrylic resin emulsions is made of a fluororesin because oil-resistant layers are formed without pinholes to prevent oil and fat components from leaching to the outside. In comparison with the above, there is a problem that the amount of the oil-resistant agent necessary for developing the equivalent oil resistance is increased. For example, Patent Documents 1 to 3 disclose a technique in which an acrylic resin is applied over several layers on a base paper using an off coater or a printing machine. Although oil resistance can be ensured, the cost is extremely high due to the large amount of time and effort.
Further, Patent Document 4 discloses a technique for applying only a single layer of an oil resistant agent with an air knife coater, but in the case of coating with an air knife coater, the coating concentration must be kept relatively low, Since drying load increases and production efficiency falls, it is not preferable.
そこで、効率的に塗布を行う手段として高速塗工が可能なトランスファーロールコーター方式の適用が考えられる。このトランスファーロールコーター方式は、オンマシンやオフマシンで使用されており、特に、ゲートロールコーターのようなトランスファーロールコーター方式は、抄紙機のサイズプレス装置としても使用されているが、耐油剤としてアクリル系樹脂を用いたトランスファーロールコーター方式による耐油紙の製造において所望の耐油性を発現させる塗工量を確保するのが困難であるというのが現状である。 Therefore, it is conceivable to apply a transfer roll coater system capable of high-speed coating as a means for efficiently applying. This transfer roll coater method is used on-machine and off-machine. In particular, a transfer roll coater method such as a gate roll coater is also used as a size press device of a paper machine, but an acrylic oil resistance agent is used. In the present situation, it is difficult to secure a coating amount that exhibits desired oil resistance in the production of oil-resistant paper by a transfer roll coater method using a resin.

本発明は、耐油層塗料に特定の増粘剤を含有させることによって、トランスファーロールコーターでの耐油層塗料の付着量を適正に確保することが可能なだけでなく、塗工欠陥のない均一な耐油層を紙支持体上に形成させることができ、且つアプリケーターロール汚れ等の操業上の問題も起こさない、高い生産性と高耐油性とを両立した耐油紙を提供することができる。 In the present invention, by including a specific thickener in the oil-resistant layer coating, not only can the amount of oil-resistant layer coating deposited on the transfer roll coater be properly secured, but also a uniform coating free of defects. It is possible to provide an oil-resistant paper which can form an oil-resistant layer on a paper support and which has both high productivity and high oil resistance without causing operational problems such as applicator roll contamination.
本発明の耐油紙は、紙支持体上に耐油性を有するアクリル系樹脂層を有するものであるが、紙支持体としては、各種の紙、板紙が使用できる。すなわち、本発明に用いる紙支持体としては特に限定されず、紙支持体の少なくとも一方の表面に後述するアクリル系樹脂を含有する耐油層を少なくとも1層設けることができるものであればよく、用途に応じて適宜選択することができる。具体的には、晒または未晒クラフト紙、上質紙、中質紙、微塗工紙、塗工紙、板紙、白板紙、ライナー、セミグラシン紙、グラシン紙、片艶紙、パーチメント紙等が挙げられる。
紙支持体の坪量には特に制限はなく、包装用としては20g/m2〜150g/m2、箱等の成型容器用としては150g/m2〜500g/m2が好適である。
The oil-resistant paper of the present invention has an acrylic resin layer having oil resistance on a paper support, and various paper and paperboard can be used as the paper support. That is, the paper support used in the present invention is not particularly limited as long as it can provide at least one oil-resistant layer containing an acrylic resin described later on at least one surface of the paper support. It can be selected as appropriate according to the conditions. Specific examples include bleached or unbleached kraft paper, fine paper, medium quality paper, finely coated paper, coated paper, paperboard, white paperboard, liner, semi-glassine paper, glassine paper, glossy paper, parchment paper, etc. It is done.
There is no particular limitation on the basis weight of the paper support, the packaging 20g / m 2 ~150g / m 2 , as the for molding vessel such as a box is preferably 150g / m 2 ~500g / m 2 .
本発明では、トランスファーロールコーターでの塗工適性を確保するために、耐油層塗料にアルカリ可溶性高分子エマルションを主成分とする増粘剤を配合することが必要である。前記増粘剤を配合しない場合、所望の耐油性を確保するための耐油層塗料の塗工量や均一な塗工面が得られない。 In the present invention, in order to ensure coating suitability with a transfer roll coater, it is necessary to add a thickener containing an alkali-soluble polymer emulsion as a main component to the oil-resistant coating. When the thickener is not blended, the coating amount of the oil resistant layer coating for ensuring the desired oil resistance and a uniform coated surface cannot be obtained.
一般に増粘剤を使用して、ハイシェア粘度を高めようとすると、同時にローシェア粘度も上昇してしまい、十分な塗工量を得る前にトランスファーロールコーターにおけるアプリケーターロール汚れを生じてしまう。本発明においては、アクリル系樹脂を含有する耐油層塗料に少なくとも1種のアルカリ可溶性高分子エマルションを主成分とする増粘剤を配合し、さらに、特定の材料を併用することによって、塗料のハイシェア粘度とローシェア粘度を制御することで、トランスファーロールコーターでの耐油層塗料の塗工適性を確保した。
In general, if a thickener is used to increase the high shear viscosity, the low shear viscosity also increases at the same time, and applicator roll contamination in the transfer roll coater occurs before a sufficient coating amount is obtained. In the present invention, an oil-resistant coating material containing an acrylic resin is blended with a thickener mainly composed of at least one alkali-soluble polymer emulsion, and a specific material is used in combination, whereby a high share of the coating material is obtained. Controlling the viscosity and low shear viscosity ensured the coating suitability of the oil-resistant coating on the transfer roll coater.
ここで、本発明において使用されるアルカリ可溶性高分子エマルションを主成分とする増粘剤としては、例えば、ソマール社製ソマレックス270K、ソマレックス300、ソマレックス440、DIC社製ボンコートHV−E、ボンコートV−E、ボンコート3750−E等を挙げることができる。 Here, as a thickener mainly composed of an alkali-soluble polymer emulsion used in the present invention, for example, Somalex 270K, Somalex 300, Somalex 440, Somalex 440, DIC Corporation Boncoat HV-E, Boncoat V- E, Boncoat 3750-E and the like.
アルカリ可溶性高分子エマルションを主成分とする増粘剤の使用量としては、特に限定するものではないが、例えば、耐油層の全固形分中の0.05〜1.0質量%であることが好ましく、0.2〜1.0質量%がさらに好ましい。
本発明では、その効果を損なわない範囲において、その他の増粘剤を併用することも可能である。その他の増粘剤としては、例えば、カルボキシメチルセルロース等の変性多糖類、アルギン酸ソーダ、変性グアーガム、ポリアクリル酸ソーダ、ポリカルボン酸ソーダ等が挙げられる。
The amount of the thickener mainly composed of the alkali-soluble polymer emulsion is not particularly limited. For example, it may be 0.05 to 1.0% by mass in the total solid content of the oil-resistant layer. Preferably, 0.2-1.0 mass% is more preferable.
In the present invention, other thickeners can be used in combination as long as the effect is not impaired. Examples of other thickeners include modified polysaccharides such as carboxymethyl cellulose, sodium alginate, modified guar gum, sodium polyacrylate, and sodium polycarboxylic acid.
本発明では、上記増粘剤と同時に使用されるローシェア粘度調整剤としては、変性ポリアミド樹脂、密実型有機フィラー、タルク等が挙げられる。なかでも変性ポリアミド樹脂、密実型有機フィラーが好ましく用いられる。
In the present invention, the Roshea viscosity modifier to be used simultaneously with the thickener, modified polyamide resins, Mitsumi organic filler and talc. Of these, modified polyamide resins and dense organic fillers are preferably used.
変性ポリアミド樹脂の中でも微カチオン性のものは、ハイシェア粘度は低下させず、ローシェア粘度を低下させるため特に好ましい。前記変性ポリアミドの具体例としては、田岡化学工業社製スミレーズレジンSPI−203(50)H、SPI−106N等が挙げられる。その使用量は特に限定されないが、例えば耐油層塗料全固形分中0.1乃至2.0質量%程度である。 Among the modified polyamide resins, a slightly cationic one is particularly preferable because it does not decrease the high shear viscosity but decreases the low shear viscosity. Specific examples of the modified polyamide include Sumire Resin SPI-203 (50) H, SPI-106N, etc. manufactured by Taoka Chemical Industries. The amount used is not particularly limited, but is, for example, about 0.1 to 2.0% by mass in the total solid content of the oil-resistant coating.
密実型有機フィラーについてもローシェア粘度を低下させる効果があるが、中でも比較的高濃度分散品が得られやすいスチレン−ブタジエン系のものが、塗料濃度低下を起こさないため好ましい。密実型有機フィラーの平均粒子径としては、特に限定されるものではないが、3μm以下のものが好ましい。密実型有機フィラーの具体例としては、日本ゼオン社製Nipol V1004等が挙げられる。その使用量は特に限定されないが、例えば耐油層塗料全固形分中1.0乃至15.0質量%程度である。 A dense organic filler also has an effect of lowering the low shear viscosity, but among them, a styrene-butadiene-based one from which a relatively high-concentration dispersion product can be obtained is preferable because it does not cause a decrease in coating concentration. The average particle size of the dense organic filler is not particularly limited, but preferably 3 μm or less. Specific examples of the dense organic filler include Nipol V1004 manufactured by Nippon Zeon Co., Ltd. The amount used is not particularly limited, but is, for example, about 1.0 to 15.0% by mass in the total solid content of the oil-resistant coating material.
タルクについては、所望の耐油性を低下させない範囲において使用可能である。タルクの具体例としては、日本タルク社製NTL、NTP−2、MS−P、MSW、MS、SWE、MSG、シムゴン、SW、SSS、日本ミストロン社製ミクロタッチ、ミストロンペーパーシリーズ(MVR、MVB、MC、MT)、ミストロンCB、ミストロン850JS、ミストロン950JSA、ミストロン750、ソープストーンA、ソープストーンC、兼松ケミカル社製NK−KCL、NK−PUC、NK−H80等が挙げられる。その使用量は特に限定されないが、例えば耐油層塗料全固形分中1乃至30質量%程度である。 About talc, it can be used in the range which does not reduce desired oil resistance. Specific examples of talc include NTL, NTP-2, MS-P, MSW, MS, SWE, MSG, Simgon, SW, SSS manufactured by Nippon Talc Co., Ltd., Microtouch manufactured by Nippon Mytron, Mistron Paper Series (MVR, MVB) MC, MT), Mistron CB, Mistron 850JS, Mistron 950JSA, Mistron 750, Soapstone A, Soapstone C, NK-KCL, NK-PUC, NK-H80 manufactured by Kanematsu Chemical Co., Ltd., and the like. The amount used is not particularly limited, but is, for example, about 1 to 30% by mass in the total solid content of the oil-resistant layer coating material.
本発明において、トランスファーロールコーターでの塗工適性を確保するために、耐油層塗料の23℃におけるハイシェア粘度とローシェア粘度(B型粘度)を制御することが好ましい。
耐油層塗料のハイシェア粘度(ハーキュレス粘度)としては、熊谷理機工業社製KRK高剪断型粘度計により8,800rpmでFボブを使用(せん断速度に換算すると1.8×105s−1である。)した場合、18〜50mPa・sが好ましく、より好ましくは20〜30mPa・sである。
ハイシェア粘度が18mPa・s未満であると、トランスファーロールコーターにおいてアプリケーターロール上の塗料が紙支持体に転写しにくくなるため、所望とする塗工量が得られず耐油性が悪化するばかりでなく、アプリケーターロール汚れを起こして操業性を低下させる。ハイシェア粘度が50mPa・sを超えると、アプリケーターロール上での塗料の転写ムラが生じ、均一な塗工面が得られず、満足な耐油性を得ることができなくなる。
In the present invention, it is preferable to control the high shear viscosity and the low shear viscosity (B-type viscosity) at 23 ° C. of the oil-resistant coating material in order to ensure coating suitability with a transfer roll coater.
As the high shear viscosity (hercules viscosity) of the oil-resistant coating, F Bob is used at 8,800 rpm with a KRK high shear type viscometer manufactured by Kumagai Riki Kogyo Co., Ltd. (1.8 × 10 5 s −1 when converted to shear rate) 18) to 50 mPa · s, more preferably 20 to 30 mPa · s.
When the high shear viscosity is less than 18 mPa · s, the coating on the applicator roll is difficult to transfer to the paper support in the transfer roll coater, so that the desired coating amount cannot be obtained and the oil resistance is deteriorated, Applicator roll stains and reduces operability. When the high shear viscosity exceeds 50 mPa · s, uneven transfer of the paint on the applicator roll occurs, a uniform coated surface cannot be obtained, and satisfactory oil resistance cannot be obtained.
耐油層塗料のローシェア粘度(東京計器社製BM型粘度計で測定した60回転の粘度)としては、500〜4,000mPa・sが好ましく、より好ましくは1,000〜3,000mPa・sである。
ローシェア粘度が500mPa・s未満の場合、アプリケーターロール上に十分な塗料が転写されないことにより、紙支持体上にも十分な耐油層塗料が付着しなくなり、満足な耐油性が得られない。逆に4,000mPa・sより高くなり過ぎると過剰な量の塗料がアプリケーターロール上に転写され、紙支持体へ転写されない分が、ロール上に蓄積してロール汚れを起こし、操業性を低下させる。したがって、操業性と十分な耐油性を有する耐油紙をトランファーロールコーティングで得るためにはハイシェア粘度とローシェア粘度の両方を制御することが好ましい。
The low shear viscosity of the oil-resistant layer paint (60-rotation viscosity measured with a BM viscometer manufactured by Tokyo Keiki Co., Ltd.) is preferably 500 to 4,000 mPa · s, more preferably 1,000 to 3,000 mPa · s. .
When the low shear viscosity is less than 500 mPa · s, sufficient coating material is not transferred onto the applicator roll, so that sufficient oil-resistant layer coating material does not adhere to the paper support and satisfactory oil resistance cannot be obtained. On the other hand, if the pressure is higher than 4,000 mPa · s, an excessive amount of paint is transferred onto the applicator roll, and the amount not transferred to the paper support accumulates on the roll and causes roll contamination, thereby reducing operability. . Therefore, in order to obtain oil-resistant paper having operability and sufficient oil resistance by transfer roll coating, it is preferable to control both high shear viscosity and low shear viscosity.
本発明の耐油層の塗工量としては、特に限定するものではないが、例えば2.5〜10.0g/m2程度の範囲で調整される。2.5g/m2を下回ると紙支持体表面のカバーリングが低下するため、アクリル系樹脂耐油剤の含有比率を上げても満足な耐油性は得られ難い。また、10.0g/m2を超える場合は、塗工後の乾燥負荷が高くなるばかりか、経済的にも不利となり好ましくない。 Although it does not specifically limit as a coating amount of the oil-resistant layer of this invention, For example, it adjusts in the range of about 2.5-10.0 g / m < 2 >. If it is less than 2.5 g / m 2 , the covering on the surface of the paper support is lowered, so that satisfactory oil resistance is hardly obtained even if the content ratio of the acrylic resin oil proofing agent is increased. On the other hand, if it exceeds 10.0 g / m 2 , not only the drying load after coating becomes high but also economically disadvantageous, such being undesirable.

○ ′: The applicator roll surface is slightly fogged but does not affect the quality.
Δ: Slight dirt accumulated on the applicator roll, making it difficult to operate for a long time.
X: The applicator roll becomes dirty in a short time and cannot be operated.
上記実施例の結果が示すように、本発明のアクリル系耐油剤樹脂にアルカリ可溶性高分子エマルションを主成分とする増粘剤を含有する耐油剤塗料を用いることにより、ロール汚れ等の操業性低下を招くことなく、トランスファーロールコーターでの塗料の付着量を適正に確保することが可能なだけでなく、塗工欠陥のない均一な耐油層を紙支持体上に形成することができるので、高耐油性を有する耐油紙を提供することができる。 As the results of the above examples show, the use of an oil-resistant paint containing a thickener mainly composed of an alkali-soluble polymer emulsion in the acrylic oil-resistant resin of the present invention reduces the operability such as roll dirt. In addition to being able to ensure an adequate amount of paint on the transfer roll coater without incurring a coating, a uniform oil-resistant layer free of coating defects can be formed on the paper support. An oil-resistant paper having oil resistance can be provided.
本発明による耐油紙は、ファーストフードなどの揚げ物を包装する容器やデパート、コンビニエンスストアなどでのテイクアウト食材の包装容器等に使用可能であり、実用上極めて有用である。 The oil-resistant paper according to the present invention can be used in containers for packaging fried foods such as fast food, packaging containers for take-out foods in department stores, convenience stores, etc., and is extremely useful in practice.
