Description
本發明係有關於一種塗料，特別是一種可藉由印刷方式塗佈於加工物件表面，並形成彈性立體塗層之塗料組成物。The present invention relates to a coating, and more particularly to a coating composition which can be applied to the surface of a workpiece by printing and form an elastic three-dimensional coating.
隨著科技的發展與經濟水平的大幅提升，現今消費大眾在進行電子產品的選購上除了對產品的實用性與功能性加以考量外，同時也會對電子產品的外觀質感與美觀設計一併地納入產品選購時的考量範圍中。With the development of technology and the substantial improvement of the economic level, today's consumer purchases in addition to the practicality and functionality of the products in addition to the product, but also the appearance and aesthetic design of the electronic products. The land is included in the scope of consideration when purchasing the product.
市面上的電子產品，例如行動電話(mobile phone)、筆記型電腦(notebook)、個人數位助理(personal digital assistant，PDA)或遊戲機等電子產品的外殼大致由塑膠、鋁鎂合金、碳纖維或鈦合金等材質所製成，並在外殼上皆製做有相當精美的圖案或刻紋，藉以增加產品的美觀、質感以及產品的辨識度。Electronic products on the market, such as mobile phones, notebooks, personal digital assistants (PDAs) or game consoles, are made of plastic, aluminum-magnesium alloy, carbon fiber or titanium. It is made of alloy and other materials, and has a beautiful pattern or engraving on the outer casing to increase the beauty, texture and product identification of the product.
舉例來說，以金屬類之鋁、鋁鎂合金或鎂合金所加工成形之外殼，若要在金屬外殼表面製作圖樣，通常會以蝕刻、雷射雕刻或陽極處理方式，在金屬外殼上形成各種高低起伏之圖樣紋路變化，例如在金屬外殼上形成金屬髮絲紋路、金屬拋光霧感或金屬咬花等紋理，使得金屬外殼除了冷冽觸感外，還增添圖樣裝飾效果。然而，在上述製造金屬外殼之圖樣處理程序中，係分別應用了物理結構破壞或是電化學表面處理方式，使得金屬外殼具備各種圖樣紋路。相對的，也提高金屬外殼的製作加工成本，且電化學表面處理需使用了極大量的溶劑，因此容易產生具高度污染性的廢棄物。For example, an outer casing formed of a metal aluminum, an aluminum-magnesium alloy or a magnesium alloy is usually formed on the metal casing by etching, laser engraving or anodizing to form a pattern on the surface of the metal casing. Pattern changes in the pattern of high and low undulations, such as the formation of metal hairline, metal polishing fog or metal bite on the metal casing, make the metal casing add a decorative effect in addition to the cold touch. However, in the above-described pattern processing procedure for manufacturing a metal casing, physical structural damage or electrochemical surface treatment is applied, respectively, so that the metal casing has various pattern patterns. In contrast, the manufacturing cost of the metal casing is also increased, and the electrochemical surface treatment requires a very large amount of solvent, so that highly polluting waste is easily generated.
若以塑化類之PC塑膠(Polycarbonate)或ABS塑膠(Acrylonitrile-butadience styrene plastics)等材質進行熱壓或射出成型之外殼，其塑膠殼體之表面通常是藉由噴塗(spray coating)油墨的方式，在塑膠外殼表面形成各種二維(two dimensional，2D)的圖樣紋路，然而，此種塑膠外殼通常僅具有顏色之變化，並無法在塑膠殼體的表面形成有各種高低起伏的紋路變化，對消費者而言，塑膠外殼係無法呈現出金屬紋路的觸摸手感。If the outer casing is hot-pressed or injection-molded with plasticized plastic (Polycarbonate) or ABS plastic (Acrylonitrile-butadience styrene plastics), the surface of the plastic casing is usually spray coated with ink. A variety of two-dimensional (2D) pattern lines are formed on the surface of the plastic case. However, such a plastic case usually only has a color change, and various types of high and low undulations are not formed on the surface of the plastic case. For consumers, the plastic case cannot show the touch of metal lines.
同時，這種噴塗油墨的方式，在塑膠外殼表面所形成的各種圖樣紋路，容易因噴塗油墨與塑膠外殼表面之間的密著性與耐磨性不佳，使得噴塗油墨極容易在塑膠外殼的使用過程中受到磨損，而導致油墨從塑膠外殼表面上剝落，進而影響塑膠外殼的美觀與降低消費者的購買意願。At the same time, the way of spraying the ink, the various pattern lines formed on the surface of the plastic shell, is easy to be poorly adhered and wear-resistant between the surface of the sprayed ink and the plastic shell, making the spray ink extremely easy to be in the plastic shell. Wear and tear during use, causing the ink to peel off the surface of the plastic casing, thereby affecting the aesthetic appearance of the plastic casing and reducing the consumer's willingness to purchase.
是以，便有一種金屬不導電真空鍍膜的技術(Non-Conductive Vacuum Metallization，NCVM)，係在塑膠外殼表面鍍上一層不導電的金屬薄膜，並搭配印刷或油漆染色方式，可在塑膠外殼的表面呈現各種豐富色彩，進而使塑膠外殼具有金屬質感，以提高產品的科技感並增加產品的附加價值。然而，此種金屬不導電真空鍍膜仍具有製作費用昂貴等問題，無形之中，會提高塑膠外殼的整體製作成本。Therefore, there is a technology of non-conductive vacuum metallization (NCVM), which is coated with a non-conductive metal film on the surface of the plastic casing and matched with printing or paint dyeing. The surface presents a variety of rich colors, which in turn gives the plastic case a metallic feel to enhance the technical sense of the product and increase the added value of the product. However, such a metal non-conductive vacuum coating still has problems such as high production cost, and invisibly increases the overall manufacturing cost of the plastic outer casing.
綜上所述，不論是金屬外殼以蝕刻、雷射雕刻或陽極處理等技術，或是塑膠外殼以金屬不導電真空鍍膜等技術，在表面形成有各種立體圖樣紋路，其加工流程均相當的繁雜、耗時，使得整體的加工成本相對的提高不少，並且上述的加工製法對於刻紋深度的拿捏不易掌控，更有可能使外殼的結構強度受到損害。是以要如何提供一種可以適用於各種板材(如金屬、塑膠等板材)的塗料，並且透過塗料的特性在板材上形成各種圖樣紋路，如各種金屬刻紋、皮革觸感或是金屬彩紋等，即為從事此行業者所亟欲研究改善之方向所在者。In summary, whether the metal casing is etched, laser engraved or anodized, or the plastic casing is made of metal non-conductive vacuum coating, various stereo patterns are formed on the surface, and the processing flow is quite complicated. Time-consuming, the overall processing cost is relatively improved, and the above-mentioned processing method is not easy to control the depth of the engraving, and is more likely to damage the structural strength of the outer casing. Therefore, how to provide a coating that can be applied to various plates (such as metal, plastic, etc.), and through the characteristics of the paint to form a variety of pattern lines on the board, such as various metal engraving, leather touch or metal color lines, etc. It is the direction of those who are engaged in this industry.
鑒於以上的問題，本發明提供一種塗料組成物，藉以改良習知加工物件表面上所形成之圖案或花紋，因所使用之塗料與加工物件表面之間的密著性和耐磨性不足，而容易於加工物件表面發生磨損與剝離的問題，以及所形成的圖案或花紋無法提供足夠的防滑性，使加工物件在使用上容易因滑脫而損壞的問題。同時，改良習知於加工物件表面在形成三維立體圖案時，所使用的加工方法過於繁雜、耗時，且容易造成加工物件毀壞而使生產製造成本增加的問題。In view of the above problems, the present invention provides a coating composition for improving the pattern or pattern formed on the surface of a conventionally processed article due to insufficient adhesion and wear resistance between the coating used and the surface of the workpiece. It is easy to cause wear and peeling of the surface of the processed article, and the formed pattern or pattern cannot provide sufficient anti-slip property, so that the processed article is easily damaged by slippage in use. At the same time, it has been conventionally known that when a three-dimensional three-dimensional pattern is formed on the surface of a processed object, the processing method used is too complicated, time consuming, and easily causes the destruction of the processed object to increase the manufacturing cost.
本發明為一種塗料組成物，包含有35%至55%重量百分比之聚酯多元醇樹脂、5%至20%重量百分比之甲苯、30%至45%重量百分比之醋酸丁酯以及3%至15%重量百分比之甲基異丁酮。The present invention is a coating composition comprising 35% to 55% by weight of a polyester polyol resin, 5% to 20% by weight of toluene, 30% to 45% by weight of butyl acetate, and 3% to 15% by weight. % by weight of methyl isobutyl ketone.

Simplify and save manufacturing costs. At the same time, the coating composition has good adhesion and wear resistance, so that when the coating composition is applied to the surface of the workpiece, it will not be worn or detached by the elastic three-dimensional coating during use of the workpiece. The surface of the workpiece cannot be covered and protected by the coating composition, and the three-dimensional pattern and texture of the surface of the workpiece are maintained, so that the slip resistance of the surface of the workpiece is increased, and the aesthetic and texture of the appearance of the workpiece is improved.

在本發明所揭露之塗料組成物製備完成後，進一步對此塗料組成物的性質進行塗膜基本特性測試。首先提供一工件，此工件可為金屬、塑膠、皮革或紙類等材質所組成之板件或片狀物，在本實施例中係以工件為一聚酯(polyethylene terephthalate，PET)塑膠板件作為舉例說明，但並不以此為限。接著以刮刀塗佈、轉印、壓印或網版印刷等方式，將塗料組成物直接塗佈於此工件的表面上。在本實施例中係以網版印刷作為舉例說明，但並不以此為限。After the preparation of the coating composition disclosed in the present invention, the basic properties of the coating composition were further tested for the properties of the coating composition. Firstly, a workpiece can be provided, which can be a plate or a sheet composed of a material such as metal, plastic, leather or paper. In this embodiment, the workpiece is a polyethylene terephthalate (PET) plastic sheet. As an example, it is not limited thereto. The coating composition is then directly applied to the surface of the workpiece by knife coating, transfer, embossing or screen printing. In the present embodiment, screen printing is exemplified, but not limited thereto.
藉由塗料組成物本身所具有的黏稠性質緊密地附著於工件表面，然後在60~120℃的環境下對此表面具有塗料組成物之工件進行烘烤作業，使塗料組成物被烘乾固化於工件表面，並於工件表面形成一彈性立體塗層。其中，烘烤作業亦可選擇以紫外光(UV) 照射方式完成塗料組成物的乾燥固化程序。By adhering to the surface of the workpiece by the viscous nature of the coating composition itself, and then baking the workpiece having the coating composition on the surface at 60 to 120 ° C, the coating composition is dried and solidified. The surface of the workpiece forms an elastic three-dimensional coating on the surface of the workpiece. Among them, the baking operation can also choose to use ultraviolet light (UV) The drying method of the coating composition is completed by the irradiation method.
之後，對此表面具有塗料組成物的工件進行密著性試驗(adhesion test)、光澤試驗(gloss test)、耐磨耗試驗(R.C.A.abrasion test)、橡皮擦耐磨耗試驗(eraser abrasion test)、耐酒精磨擦試驗(alcohol abrasion test)、硬度試驗(hardness test)及高溫高濕試驗(humidity and temperature test)等彈性立體塗層特性測試，其結果如下表一所示。Thereafter, the workpiece having the coating composition on the surface is subjected to an adhesion test, a gloss test, a RCAabrasion test, an eraser abrasion test, The elastic stereoscopic coating properties tests such as alcohol abrasion test, hardness test and humidity and temperature test are shown in Table 1.
如表一所示，其中密著性試驗(adhesion test)是以美國材料試驗協會(American Society for Testing and Materials，ASTM)D3359所規範之附著力膠帶試驗法來進行。此方法是以小刀在彈性立體塗層上切割試驗方格，然後以軟毛刷清潔表面。接著以3M公司所製造之3M 600膠帶貼附於方格上，並以橡皮擦施加壓力於膠帶上，使膠帶與工件表面上的試驗方格貼緊。然後以90°角拉起膠帶，此時在工件表面上附著力不佳的試驗方格將受到膠帶的黏著而脫離於工件表面。接著再重覆膠帶貼附於方格上，再以90°角拉起膠帶的步驟2次。之後檢視並計算試驗方格於工件表面上脫離的情形，並將彈性立體塗層在工件表面上的密著能力分為0B至5B等六個等級，0B代表65%以上的被移除率，1B代表15~65%的被移除率，2B代表15~35%的被移除率，3B代表5~15%的被移除率，4B代表低於5%的被移除率，以及而5B則代表被移除率為零。As shown in Table 1, the adhesion test is carried out by the Adhesive Tape Test Method as specified by American Society for Testing and Materials (ASTM) D3359. This method uses a knife to cut the test square on the elastic three-dimensional coating, and then clean the surface with a soft brush. Next, 3M 600 tape made by 3M Company was attached to the square, and pressure was applied to the tape with an eraser to make the tape adhere to the test square on the surface of the workpiece. The tape is then pulled up at an angle of 90°, at which point the test panel with poor adhesion on the surface of the workpiece will be adhered by the tape and detached from the surface of the workpiece. Then repeat the step of attaching the tape to the square and then pulling the tape at a 90° angle twice. After that, the condition of the test square on the surface of the workpiece is examined and calculated, and the adhesion ability of the elastic three-dimensional coating on the surface of the workpiece is divided into six levels of 0B to 5B, and 0B represents a removal rate of more than 65%. 1B represents the removal rate of 15~65%, 2B represents the removal rate of 15~35%, 3B represents the removal rate of 5~15%, 4B represents the removal rate of less than 5%, and 5B means that the removal rate is zero.
在密著性試驗結果中，本發明所揭露之塗料組成物與工件表面之間的密著能力可達到5B的標準，即彈性立體塗層自工件表面上的被移除率為零。因此，本發明所揭露的塗料組成物可緊密的與工件表面結合，而不會有脫著的情形發生。In the results of the adhesion test, the adhesion between the coating composition of the present invention and the surface of the workpiece can reach the standard of 5B, that is, the removal rate of the elastic three-dimensional coating from the surface of the workpiece is zero.

接著，再以美國材料試驗協會(ASTM) F2357所規範的方法進行耐磨耗試驗(R.C.A. abrasion test)。耐磨耗試驗是於RCA磨耗試驗機上裝置175克重的砝碼與Norman公司所製造的2060MK紙帶。然後將表面具有塗料組成物的工件固定於RCA磨耗試驗機上，並調整試驗桿使達到水平，然後進行耐磨耗試驗，使以紙帶與彈性立體塗層磨擦，並於一定之迴轉數下查看塗膜層之耐磨耗效果，再以60倍顯微鏡觀測彈性立體塗層是否被移除於工件表面。Next, the abrasion resistance test (R.C.A. abrasion test) was carried out in accordance with the method specified by the American Society for Testing and Materials (ASTM) F2357. The abrasion resistance test was performed on a RCA abrasion tester with a 175 gram weight and a 2060 MK paper tape manufactured by Norman. Then, the workpiece with the coating composition on the surface is fixed on the RCA abrasion testing machine, and the test rod is adjusted to reach the level, and then the abrasion resistance test is performed to rub the paper tape with the elastic three-dimensional coating, and under a certain number of revolutions Look at the wear resistance of the coating layer, and then observe whether the elastic three-dimensional coating is removed on the surface of the workpiece with a 60-fold microscope.
在耐磨耗試驗的結果中，表面具有塗料組成物之工件在經過100回的磨耗後，並未觀測到工件的表面露出於彈性立體塗層外，因此彈性立體塗層仍未被完全的磨耗，此一結果顯示本發明所揭露之塗料組成物具有良好的耐磨耗特性。In the results of the abrasion resistance test, after the workpiece having the coating composition on the surface was subjected to 100 times of abrasion, the surface of the workpiece was not observed to be exposed outside the elastic three-dimensional coating, so the elastic three-dimensional coating was still not completely worn. This result shows that the coating composition disclosed in the present invention has good wear resistance characteristics.
在另一耐磨耗試驗中，係以橡皮擦耐磨耗試驗(eraser abrasion test)進行。其係於試驗儀器之測試桿上裝置500克重的砝碼與一橡皮擦(EF74號)，並將表面具有塗料組成物的工件固定於試驗儀器上，接著以試驗距離5公分，每分鐘60來回的測定方式進行橡皮擦耐磨耗試驗。在經過2000回的試驗後，仍未觀測到工件的表面露出於彈性立體塗層外。In another abrasion resistance test, it was carried out with an eraser abrasion test. It is equipped with a 500 gram weight and an eraser (EF74) on the test rod of the test instrument, and the workpiece with the coating composition on the surface is fixed on the test instrument, followed by a test distance of 5 cm, 60 minutes per minute. The back and forth measurement method was carried out for the eraser abrasion resistance test. After 2000 passes of the test, the surface of the workpiece was not observed to be exposed outside the elastic three-dimensional coating.
耐酒精磨擦試驗(alcohol abrasion test)係以美國材料試驗協會(ASTM) D1308所規範的方法進行。其係於耐酒精磨擦儀之試驗桿上裝置500克重的砝碼與一浸含百分之95酒精之紗布。然後將表面具有塗料組成物之工件固定於耐酒精磨擦儀上，以試驗距離5公分，每分鐘60來回的測定方式進行耐酒精磨擦試驗。在經過150回的試驗後，仍未觀測到工件的表面露出於彈性立體塗層外。The alcohol abrasion test was carried out in accordance with the method specified by ASTM D1308. It is equipped with a 500 gram weight and a 95% alcohol gauze on a test rod of an alcohol-resistant abrasive. Then, the workpiece having the coating composition on the surface was fixed on an alcohol-resistant rubbing instrument, and an alcohol-resistant rubbing test was performed at a test distance of 5 cm and a measurement method of 60 round trips per minute. After 150 tests, the surface of the workpiece was not observed to be exposed outside the elastic three-dimensional coating.
因此，綜合以上之(紙帶式)耐磨耗試驗、橡皮擦耐磨耗試驗及耐酒精磨擦試驗的結果，本發明所揭露之塗料組成物在工件表面上所形成的彈性立體塗層具有相當良好的耐磨耗特性。Therefore, in combination with the above (paper tape type) abrasion resistance test, the eraser abrasion resistance test, and the alcohol-resistant abrasion test, the elastic three-dimensional coating formed on the surface of the workpiece by the coating composition disclosed by the present invention has a considerable Good wear resistance.

It first exposes a pencil lead (MITSUBISHI UNI, manufactured by Mitsubishi Corporation) about 0.5 to 0.6 cm. The pencil lead is placed at a 90-degree angle with the No. 400 sandpaper, and the pencil core of the pencil is worn to a flat and unnotched state by a 400-grit sandpaper. Then, the pencil was placed in a hardness tester at a 45° angle, and the pencil head was scraped on the elastic three-dimensional coating on the surface of the workpiece under the condition of a test load of 500 g. In this hardness test, a pencil with a refill hardness of H cannot cut through the elastic three-dimensional coating formed on the surface of the workpiece. Therefore, the hardness of the elastic three-dimensional coating formed on the surface of the workpiece by the coating composition disclosed by the present invention can at least reach the standard of hardness H.
之後，對表面具有塗料組成物的工件進行高溫高濕試驗(humidity and temperature test)，其係將表面具有塗料組成物之工件放置於攝氏溫度85度、相對濕度百分之90的環境中48小時。然後將表面具有塗料組成物之工件從上述之環境中取出，並靜置於室溫1小時後進行觀測，同時再次進行密著性試驗，藉以測試高溫、高濕的環境是否對塗料組成物與工件表面之間的密著性造成影響。在此一高溫高濕試驗中，表面具有塗料組成物之工件在外觀上並未受到高溫、高濕的影響而產生改變。並且在密著性試驗中，塗料組成物於工件表面上所形成的彈性立體塗層仍可達到4B以上的密著能力。Thereafter, a workpiece having a coating composition on the surface is subjected to a humidity and temperature test, and the workpiece having the coating composition on the surface is placed in an environment of 85 degrees Celsius and 90% relative humidity for 48 hours. .
