Description
本発明は、食品器具の表面に疏水高分子金属複合皮膜を覆設する方法に関し、特に、有効的に食品器具の疏水性、抗粘着性を高め、且つ優れた表面の耐摩耗能力を有する食品器具表面処理の技術に関する。 The present invention relates to a method of lining a hydrophobic polymer metal composite film on the surface of a food utensil, and in particular, a food having an excellent surface abrasion resistance ability while effectively enhancing the water resistance and anti-adhesiveness of the food utensil. Regarding the technology of surface treatment of appliances.
デュポン社の生産するポリテトラフルオロエチレン塗料は、すでに、例えば炊飯釜や炒め鍋、ハンバーグ・ステーキプレート、フライパン、バーベキュープレート、オーブンプレート、トーストボックス、各種ケーキ型、各種クッキー型、ホットプレート、パイプレート及び食品用刀具等の、あらゆる食品器具上に応用されている。具体的な応用範囲としては、ポリテトラフルオロエチレン塗料を直接食品器具の搭載表面（食品を搭載する内面や底面、または食品用刀具の刀面等）に吹き付けることで、食品器具の表面に不粘着層を形成させるものである。この方法によって、ポリテトラフルオロエチレンを塗布された食品器具の表面は不粘着特性を得る。またこの方法においては、ポリテトラフルオロエチレンにより食品器具の清浄がし易い、粘着物が付きにくいという効果がもたらされるが、ポリテトラフルオロエチレンを塗布された食品器具の不粘着層を有する表面は、耐摩耗能力に優れず、長期にわたる使用や不適切な使用、または過度の清浄と言った原因から不粘着層を損傷させてしまい、ないしは不粘着層の雑屑や化学成分等がかき傷や裂け目から滲み出て食品内に混ざり、食品の安全に対する懸念を生む状況となっている。 Dupont's polytetrafluoroethylene paints are already available, for example, in rice cookers, stir-fry pans, hamburger steak plates, frying pans, barbecue plates, oven plates, toast boxes, various cake molds, various cookie molds, hot plates, and pipe rates. And it is applied to all food utensils such as food swords. As a specific application range, the polytetrafluoroethylene paint is directly sprayed on the mounting surface of the food appliance (the inner surface or bottom surface on which the food is mounted, or the sword surface of the food sword tool, etc.) to prevent adhesion to the surface of the food appliance. It forms a layer. By this method, the surface of the food utensil coated with polytetrafluoroethylene obtains non-adhesive properties. Further, in this method, the polytetrafluoroethylene has the effect of making it easy to clean the food utensil and making it difficult for sticky substances to adhere to it. However, the surface of the food utensil coated with polytetrafluoroethylene having a non-adhesive layer is It has poor wear resistance and damages the non-adhesive layer due to long-term use, improper use, or excessive cleaning, or the non-adhesive layer's dust and chemical components are scratched or crevices. It oozes out of the food and mixes with the food, creating concerns about food safety.
また、アルミベース金属間化合物の構造は独特の性質を有しており、異なる多元系合金のアルミベース金属間化合物材料は、例えば水素吸蔵材、遮熱コーティング，選択性光線吸収器、化学反応器、抗粘着コーティング、触媒剤粒子、及び強度の低い合金を強化する分散型強度粒子といった部分に広く応用されている。アルミニウム−銅−鉄の三元系合金は成分や熱力学の条件の違いにより、それぞれ結晶相、アルミベース金属間化合物、非結晶相を得る。アルミニウム系のアルミベース金属間化合物、例えばアルミニウム−銅−鉄が含む三つの元素はいずれも金属であるため、導電性に優れているが、ただこの三つの元素により組成されるアルミベース金属間化合物構造は、導電率がおよそ金属の一万分の一であり、ひいては成分が類似する非晶質よりも低く、また完美で整ったアルミベース金属間化合物構造であればあるほど、導電率は低くなり、丁度金属とは相反するものとなる。言い換えると、アルミベース金属間化合物構造は、金属元素により構成されるものの陶磁に類する特性を呈しており、一般的な金属及び非晶金属とは大きく異なっている。 In addition, the structure of the aluminum-based intermetallic compound has unique properties, and the aluminum-based intermetallic compound material of different multi-element alloys is, for example, a hydrogen storage material, a heat shield coating, a selective light absorber, and a chemical reactor. , Anti-adhesive coatings, catalyst particles, and dispersed strength particles that reinforce low strength alloys. The aluminum-copper-iron ternary alloy obtains a crystalline phase, an aluminum-based intermetallic compound, and a non-crystalline phase, respectively, depending on the difference in composition and thermodynamic conditions. Aluminum-based aluminum-based intermetallic compounds, for example, the three elements contained in aluminum-copper-iron are all metals, so they are excellent in conductivity, but only aluminum-based intermetallic compounds composed of these three elements. The structure has a conductivity of about 1 / 10,000 of that of a metal, which is lower than that of an amorphous material having similar components, and the more beautiful and well-organized aluminum-based intermetallic compound structure, the lower the conductivity. Therefore, it is exactly the opposite of metal. In other words, the aluminum-based intermetallic compound structure is composed of metal elements but exhibits properties similar to those of ceramics, and is significantly different from general metals and amorphous metals.
更に、アルミニウム（Ａｌｘ）、銅（Ｃｕｙ）、鉄（Ｆｅｚ）系といったアルミベース金属間化合物構造の材料により製成された疏水合金膜は、高疏水性、高抗粘着性の特性を有しているので、疏水合金膜の接触角は１００度以上に達する。よって、食品器具の表面に覆設できる疏水合金膜の開発を通じて、ポリテトラフルオロエチレン（Ｐ．Ｔ．Ｆ．Ｅ）の使用上の疑問を払拭すること、或いはポリテトラフルオロエチレンと合わせることで食品器具表面の処理技術へと応用することは、関連業界による達成が待たれている。 Furthermore, aluminum (Al x), copper (Cu y), iron (Fe z) hydrophobic alloy film was made manufactured by a material of an aluminum-based intermetallic compound structures such systems, high hydrophobic, high anti-tack properties Since it has, the contact angle of the hydrophobic alloy film reaches 100 degrees or more. Therefore, through the development of a water alloy film that can be overlaid on the surface of food utensils, the doubts about the use of polytetrafluoroethylene (PTFE) can be dispelled, or by combining with polytetrafluoroethylene, food products can be used. The application to the surface treatment technology of equipment is expected to be achieved by related industries.

The purpose is to obtain advantages such as high water resistance, high anti-adhesiveness, and excellent surface abrasion resistance on the mounting surface of food utensils. The technical means for achieving the main object of the present invention is to make a spray suspension by stirring and mixing a polytetrafluoroethylene solution and an aluminum-based intermetallic compound powder, and the spray suspension is used as a food appliance. By spraying on the surface of the food utensil, at least one coating is formed on the surface of the food utensil, and by heating the coating on the mounting surface of the food utensil, it is molded and solidified to form a further water-stained polymer / metal composite film. That is.

分かりやすく言うと、上述の食品器具１０の表面１１は搭載表面を言う。図２に示す食品器具１０はトーストボックスであり、トーストボックスの搭載表面は内面及び底面である。また、図３に示す食品器具１０は波刃包丁であり、この波刃包丁の搭載表面は二つの刀面、及び刀背である。加えて、図４に示す食品器具１０はオーブンプレートであり、このオーブンプレートの搭載表面は底面となる。 To put it simply, the surface 11 of the food utensil 10 described above refers to the mounting surface. The food appliance 10 shown in FIG. 2 is a toast box, and the mounting surface of the toast box is an inner surface and a bottom surface. The food appliance 10 shown in FIG. 3 is a wave blade knife, and the mounting surface of the wave blade knife is two sword surfaces and a sword spine. In addition, the food utensil 10 shown in FIG. 4 is an oven plate, and the mounting surface of the oven plate is the bottom surface.
本発明による疏水高分子／金属複合皮膜３０が覆設される食品器具１０は、表面エネルギーが比較的低いため、比較的高い疏水性を有する。加熱、成型及び固化後に測定実験を行っているが、測定においては、本発明による疏水高分子／金属複合皮膜３０が覆設される食品器具１０の疏水性の接触角は１４０から１５０度に達し、図６に示すように、卓越した疏水性と抗粘着効果を有する。 The food appliance 10 on which the hydrophobic polymer / metal composite film 30 according to the present invention is covered has a relatively high hydrophobicity because the surface energy is relatively low. Measurement experiments are conducted after heating, molding, and solidification. In the measurement, the hydrophobic contact angle of the food appliance 10 on which the hydrophobic polymer / metal composite film 30 according to the present invention is covered reaches 140 to 150 degrees. , As shown in FIG. 6, has excellent water resistance and anti-adhesive effect.
本発明による疏水高分子／金属複合皮膜３０が覆設される食品器具１０は、耐摩耗の測定実験（ＧＢ／Ｔ ３２３８９−２０１５耐摩耗試験を参考）を行っているが、測定においては、元々の基準であるポリテトラフルオロエチレンのコーティングのみの１０００回から７０００回以上へと大幅に上昇しており、本発明は卓越した耐摩耗性を有することが分かった。本発明ではそれぞれ異なる重量比のアルミベース金属間化合物粉末２０が添加されるものに対し耐摩耗回数の比較実験を行ったが、アルミベース金属間化合物粉末２０の重量比が０％の時、耐摩耗回数は１０００回であり、アルミベース金属間化合物粉末２０の重量比がそれぞれ５％、１０％、１５％そして２０％の時、耐摩耗回数はそれぞれ３５００回、３８００回、６０００回そして７５００回であった。よって、アルミベース金属間化合物粉末２０の重量比が大きくなるにつれ、耐摩耗回数も多くなることが分かる。 The food utensil 10 on which the water-stained polymer / metal composite film 30 according to the present invention is covered has been subjected to an abrasion resistance measurement experiment (refer to the GB / T 32389-2015 abrasion resistance test), but the measurement was originally performed. It was found that the present invention has excellent wear resistance, as it has increased significantly from 1000 times to 7000 times or more only for the coating of polytetrafluoroethylene, which is the standard of the above. In the present invention, a comparative experiment of the number of times of wear resistance was carried out for the aluminum-based intermetallic compound powder 20 to which different weight ratios were added. When the weight ratio of the aluminum-based intermetallic compound powder 20 was 0%, the resistance was reduced. The number of times of wear is 1000 times, and when the weight ratio of the aluminum-based intermetallic compound powder 20 is 5%, 10%, 15% and 20%, respectively, the number of times of wear resistance is 3500 times, 3800 times, 6000 times and 7500 times, respectively. Met. Therefore, it can be seen that as the weight ratio of the aluminum-based intermetallic compound powder 20 increases, the number of times of wear resistance also increases.
本発明による疏水高分子／金属複合皮膜３０が覆設される食品器具１０は、５％の塩化 ナトリウム溶液（ＮＡＣＬ）ミストによる防腐蝕測定実験（ＧＢ／Ｔ ３２３８９−２０１５耐塩性試験を参考）を行っており、５％のＮＡＣＬミストによる試験の時間が４８時間から１７５時間に伸びていることから、本発明が卓越した対塩霧防腐蝕能力を有することが分かっている。 The food appliance 10 on which the water polymer / metal composite film 30 according to the present invention is covered is subjected to an anticorrosion measurement experiment using a 5% sodium chloride solution (NACL) mist (see GB / T 32389-2015 salt tolerance test). It is known that the present invention has excellent anti-salt fog anticorrosion ability, as the test time with 5% NaCl mist has been extended from 48 hours to 175 hours.
本発明による疏水高分子／金属複合皮膜３０が覆設される食品器具１０は、関連する食品安全検査の実施を台湾標準（ＳＧＳ）に委託しており、検査により、本発明は中国大陸の食品安全法である、１）ＧＢ ４８０６．１−２０１６（食品安全国家標準食品接触材料及製品通用安全要求）、２）ＧＢ ４８０６．１０−２０１６（食品安全国家標準 食品接触塗料及塗層）、そして３）ＧＢ ９６８５−２０１６（食品安全国家標準 食品接触材料及製品用添加剤使用標準）を満たしていることが分かった。 The food appliance 10 on which the water polymer / metal composite film 30 according to the present invention is covered has outsourced the implementation of the related food safety inspection to the Taiwan Standard (SGS), and by the inspection, the present invention is the food of mainland China. Safety Laws: 1) GB 4806.1-2016 (Food Safety National Standard Food Contact Materials and Product Safety Requirements), 2) GB 4806.1-2016 (Food Safety National Standard Food Contact Paints and Coating Layers), and 3) It was found that GB 9685-2016 (Food Safety National Standard Food Contact Materials and Product Additive Use Standard) was satisfied.
以上をまとめると、本発明は、従来のポリテトラフルオロエチレン（Ｐ．Ｔ．Ｆ．Ｅ）の使用上の懸念を払拭し、飲食店で広く使用されうるものであり、例えば疏水高分子／金属複合皮膜３０を食品器具１０（例えば炊飯釜、炒め鍋、ハンバーグ・ステーキプレート、フライパン、バーベキュープレート、オーブンプレート、トーストボックス、各種ケーキ型、各種クッキー型、ホットプレート、パイプレート及び食品用刀具等）の搭載表面１１に覆設することで、疏水高分子／金属複合皮膜３０の疏水性の接触角が１４０から１５０度に達することにより卓越した効果を達する。その効果は、主に以下の二点である。
１．卓越した疏水及び抗粘着等の特性に加え、有効的に抗粘着効果を持続させるので、食品器具に粘着物が付着して清浄しにくい状況が起こりにくくなる。
２．卓越した耐摩耗性及び対塩霧防腐蝕能力を有するため、食品器具表面が出力に優れないためにスクラッチが残るという状況を予防し、且つ食品器具の使用寿命を持続させることができる。
Summarizing the above, the present invention dispels concerns about the use of conventional polytetrafluoroethylene (PTFE) and can be widely used in restaurants, for example, a hydrophobic polymer / metal. The composite film 30 is applied to food utensils 10 (for example, rice cooker, frying pan, hamburger steak plate, frying pan, barbecue plate, oven plate, toast box, various cake molds, various cookie molds, hot plates, piperates, food swords, etc.) By lining it on the mounting surface 11 of the above, the water-repellent contact angle of the hydrophobic polymer / metal composite film 30 reaches 140 to 150 degrees, thereby achieving an excellent effect. The effects are mainly the following two points.
1. 1. In addition to excellent water-sucking and anti-adhesive properties, the anti-adhesive effect is effectively maintained, so that it is difficult for sticky substances to adhere to food utensils and make it difficult to clean.
2. 2. Since it has excellent wear resistance and anti-corrosion ability against salt fog, it is possible to prevent the situation where scratches remain due to the poor output of the surface of the food utensil, and to extend the service life of the food utensil.
