Description

抗霧塗佈組成物Anti-Fog Coating Composition

關於抗霧塗佈組成物之化學性質。About the chemical properties of the anti-fog coating composition.

聚合物的其中一種性質是透明度或清晰度，在各種應用中採用此性質，例如，包裝內部需要被看到的物件，特別是食品包裝；農業應用，諸如具有透明塑料作為覆蓋物以控制溫度並允許光通過的溫室；公共衛生應用，諸如透明手術口罩等等。然而，在此透明材料的使用中所發現的問題是形成在材料表面的霧氣，這會降低材料的清晰度。因此，已經進行許多研究以獲得避免在材料表面形成霧氣的方法。One of the properties of polymers is transparency or clarity, which is exploited in a variety of applications, for example, items that need to be seen inside packaging, especially food packaging; agricultural applications, such as having clear plastic as a cover to control temperature and Greenhouses that allow light to pass through; public health applications such as transparent surgical masks, etc. However, a problem found in the use of this transparent material is the formation of fog on the surface of the material, which reduces the clarity of the material. Therefore, many studies have been carried out to obtain methods to avoid the formation of fog on the surface of materials.

舉例來說，國際專利編號第PCT/US2009/065703號揭露一種抗霧塗佈組成物，包含親水性聚合物、基於聚合物的100重量%的0.5至25重量%數量範圍中的陰離子界面活性劑、基於聚合物的100重量%的0至60重量%數量範圍中的無機氧化物顆粒以及水性溶劑。For example, International Patent No. PCT/US2009/065703 discloses an anti-fog coating composition comprising a hydrophilic polymer, an anionic surfactant in an amount ranging from 0.5 to 25% by weight based on 100% by weight of the polymer , inorganic oxide particles in an amount ranging from 0 to 60% by weight based on 100% by weight of the polymer, and an aqueous solvent.

歐洲專利號第EP0600053 B1號揭露一種聚合物組成物，在育成（incubation）後，該聚合物組成物不溶於水中且顯示抗霧性質。聚合物組成物包含（a）具有20,000至200,000平均分子量的水溶性聚乙烯醇聚合物以及具有30,000至400,000平均分子量的水溶性聚乙烯吡咯烷酮聚合物以及（b）交聯劑，包含基於組成物中所含有的非揮發性成分重量的高達50重量%的三聚氰胺、礦物酸或強有機酸。European Patent No. EP0600053 B1 discloses a polymer composition which is insoluble in water and exhibits anti-fog properties after incubation. A polymer composition comprising (a) a water-soluble polyvinyl alcohol polymer having an average molecular weight of 20,000 to 200,000 and a water-soluble polyvinylpyrrolidone polymer having an average molecular weight of 30,000 to 400,000 and (b) a crosslinking agent, comprising Contains up to 50% by weight of non-volatile constituents of melamine, mineral acids or strong organic acids.

然而前述專利並未揭露根據本發明的抗霧塗佈組成物。However, the aforementioned patents do not disclose the anti-fog coating composition according to the present invention.

本發明亦關於一種物件，包含基板與所述抗霧塗佈組成物。The present invention also relates to an object, including a substrate and the anti-fog coating composition.

根據本發明的抗霧塗佈組成物具有良好的抗霧性質，使本發明的抗霧塗佈組成物適用於各種基板，例如，包含聚丙烯（polypropylene）、聚對苯二甲酸乙二醇酯（polyethylene terephthalate）或聚苯乙烯（polystyrene）作為成分的基板，而不會使經塗佈基板朦朧或模糊不清且不會使基板表面沾染油汙。此外，此抗霧組成物亦具有長的保存期限。The anti-fog coating composition according to the present invention has good anti-fog properties, making the anti-fog coating composition of the present invention suitable for various substrates, for example, containing polypropylene (polypropylene), polyethylene terephthalate (polyethylene terephthalate) or polystyrene (polystyrene) as an ingredient without hazy or clouding the coated substrate and without oiling the substrate surface. In addition, the anti-fog composition also has a long shelf life.

在此，除非特別指出，用語「界面活性劑」代表在相同分子中包含親水（極性）部分與疏水（非極性）部分的分子，這使抗霧塗佈組成物具有較低的表面張力。Herein, unless otherwise specified, the term "surfactant" refers to a molecule comprising a hydrophilic (polar) part and a hydrophobic (non-polar) part in the same molecule, which makes the anti-fog coating composition have a lower surface tension.

相較於包含C14-C17仲烷基磺酸鈉界面活性劑的抗霧塗佈組成物（PP比較片材4與PET比較片材4）、包含聚甘油-10-油酸酯與月桂醇乙烯醚硫酸鈉鹽混合物的界面活性劑的抗霧塗佈組成物（PP比較片材5與PET比較片材5）與包含月桂醇乙烯醚硫酸鈉鹽界面活性劑的抗霧塗佈組成物（PP比較片材6與PET比較片材6），根據本發明的塗佈組成物在聚丙烯基板（PP片材1至8）上具有防止冷狀態下霧化的較佳效率以及在聚對苯二甲酸基板（PET片材1至8）上具有防止熱狀態下霧化的較佳效率。Compared with the anti-fog coating composition (PP comparative sheet 4 and PET comparative sheet 4) containing C14-C17 secondary alkylsulfonate sodium surfactant, containing polyglyceryl-10-oleate and lauryl vinyl The anti-fog coating composition (PP comparison sheet 5 and PET comparison sheet 5) of the surfactant of the ether sulfate sodium salt mixture and the anti-fog coating composition containing the surfactant of lauryl vinyl ether sulfate sodium salt (PP Comparative Sheet 6 vs. PET Comparative Sheet 6), the coating composition according to the invention has better efficiency in preventing fogging in the cold state on polypropylene substrates (PP Sheets 1 to 8) Formic acid substrates (PET sheets 1 to 8) have better efficiency against fogging in hot state.

相較於包含十二苯磺酸鈉界面活性劑的抗霧塗佈組成物（PET比較片材2與PET比較片材3）、包含C14-C17仲烷基磺酸鈉界面活性劑的抗霧塗佈組成物（PET比較片材4）、包含聚甘油-10-油酸酯與月桂醇乙烯醚硫酸鈉鹽混合物的界面活性劑的抗霧塗佈組成物（PET比較片材5）與包含月桂醇乙烯醚硫酸鈉鹽界面活性劑的抗霧塗佈組成物（PET比較片材6），根據本發明的抗霧塗佈組成物在聚對苯二甲酸基板（PET片材1至8）上具有防止冷狀態下霧化的較佳效率。Compared to the anti-fog coating composition containing sodium dodecylsulfonate surfactant (PET comparative sheet 2 and PET comparative sheet 3), the anti-fog coating composition containing C14-C17 secondary alkylsulfonate sodium surfactant Coating composition (PET comparative sheet 4), anti-fogging coating composition (PET comparative sheet 5) containing a mixture of polyglyceryl-10-oleate and sodium lauryl vinyl ether sulfate surfactant (PET comparative sheet 5) and containing Anti-fog coating composition of sodium lauryl vinyl ether sulfate surfactant (PET comparative sheet 6), anti-fog coating composition according to the present invention on polyterephthalic acid substrate (PET sheets 1 to 8) It has better efficiency in preventing fogging in cold state.
