Description
本發明係關於金屬抽線的前處理，特別是關於一種皮膜處理液及使用皮膜處理液的鈦鎳合金盤元的抽線預處理方法。The present invention relates to the pretreatment of metal wire drawing, in particular to a method for wire drawing pretreatment of a film treatment liquid and a titanium-nickel alloy disc element using the film treatment liquid.
傳統金屬抽線前處理所使用的處理液會依據金屬類型而採用不同類型的處理液，例如碳鋼會使用磷酸鹽類的處理液，不鏽鋼會使用草酸鹽類的處理液。而鎳合金常見會使用草酸鹽類或硫酸鹽類的處理液。The treatment liquid used in the pretreatment of traditional metal wire drawing will use different types of treatment liquid according to the type of metal. For example, carbon steel uses phosphate-based treatment liquid, and stainless steel uses oxalate-based treatment liquid. For nickel alloys, oxalate or sulfate treatment solutions are commonly used.
經草酸鹽類處理液處理後，在合金線材外表面所形成的皮膜的附著型佳，有利於多次抽線，但是缺點是製程設備及操作較複雜、成本高、環安疑慮高(產生含重金屬廢酸)、以及皮膜不易去除，不利於重新處理。而硫酸鹽類處理液的製程設備及操作相對簡易、成本低、安全性高、皮膜易清洗，有利於重覆皮膜處理，但是皮膜附著性較差，不利於多次抽線，而且皮膜容易吸潮，不利儲放線材。此外，硫酸鹽類處理液需要保持在60℃至80℃的環境中，因此還需要額外保溫方式，也增加了能源的消耗。After treatment with oxalate treatment liquid, the film formed on the outer surface of the alloy wire has a good adhesion type, which is beneficial to multiple wire drawing. However, the disadvantage is that the process equipment and operation are more complicated, the cost is high, and the environmental safety concerns are high. Heavy metal waste acid) and the film are not easy to remove, which is not conducive to reprocessing. The processing equipment and operation of the sulfate treatment liquid are relatively simple, low cost, high safety, and the film is easy to clean, which is conducive to repeated film treatment, but the film has poor adhesion, which is not conducive to multiple thread draws, and the film is easy to absorb moisture , Unfavorable to store wires. In addition, the sulfate treatment solution needs to be kept in an environment of 60°C to 80°C, so additional heat preservation methods are required, which also increases energy consumption.
故，必要提供一種皮膜處理液及使用皮膜處理液的鈦鎳合金盤元的抽線預處理方法，以解決習用技術所存在的問題。Therefore, it is necessary to provide a film treatment liquid and a wire drawing pretreatment method of the titanium-nickel alloy disc element using the film treatment liquid to solve the problems of the conventional technology.

請參照第1圖，第1圖是常見金屬抽線製程的一示意圖。為了提升運輸效率及存放的便利性，金屬材料多會盤捲成一盤元10。該盤元會通過一矯直輪組20後，進入一眼模30進行抽線。由於該眼模為金屬材料(例如鎢)所製成，在抽線過程中該眼模可能會對刮傷金屬線材表面，所以在抽線前會金屬表面形成皮膜及披覆抽線粉。而習知的皮膜處理液存在前述的多種問題。Please refer to Figure 1.

After passing through a
本發明的一實施例提供了一種皮膜處理液，用於一鈦鎳合金盤元的一抽線預處理方法，其包含：一磷酸鋁溶液，在該磷酸鋁溶液中磷與鋁的一重量比為2.5：1至4：1；及水，在該皮膜處理液中該水的重量百分比為65%至80%。其中該磷酸鋁溶液中的磷可以選自磷酸及磷酸二氫鋁所組成的群組，該磷酸鋁溶液中的鋁可以選自鋁金屬、氫氧化鋁、氧化鋁及磷酸二氫鋁所組成的群組。An embodiment of the present invention provides a coating treatment solution for a wire-drawing pretreatment method for a titanium-nickel alloy disk element, which comprises: an aluminum phosphate solution, and a weight ratio of phosphorus to aluminum in the aluminum phosphate solution It is 2.5:1 to 4:1; and water, the weight percentage of the water in the film treatment liquid is 65% to 80%. The phosphorus in the aluminum phosphate solution can be selected from the group consisting of phosphoric acid and aluminum dihydrogen phosphate, and the aluminum in the aluminum phosphate solution can be selected from aluminum metal, aluminum hydroxide, aluminum oxide, and aluminum dihydrogen phosphate. Group.
該皮膜處理液更可以包含：鋯鹽，且該鋯鹽與該磷酸鋁溶液的重量比為5：100至20：100。該鋯鹽包含一碳酸鋯鉀KaZrO(CO 3) 2或一碳酸鋯銨(NH 4) 2ZrO(CO 3) 2等不含有機分子之脫水劑。碳酸鋯鹽溶於水中 形成碳酸鋯離子，經塗覆加熱後碳酸根解離產生CO 2揮發，-O-Zr-O-與 HO-P-O-Al-O-P-脱水反應形成-O(-Zr-O-P-O-Al-O-P)n-的具抗濕性多孔性皮膜結構。如果鋯鹽的含量過低，也就是該鋯鹽與磷酸鋁溶液的重量比小於5：100則所形成的皮膜抗濕性差。 The film treatment solution may further include: zirconium salt, and the weight ratio of the zirconium salt to the aluminum phosphate solution is 5:100 to 20:100. The zirconium salt contains potassium zirconium monocarbonate KaZrO(CO 3 ) 2 or ammonium zirconium monocarbonate (NH 4 ) 2 ZrO(CO 3 ) 2 and other dehydrating agents without organic molecules. The zirconium carbonate salt is dissolved in water to form zirconium carbonate ion. After coating and heating, the carbonate dissociates to produce CO 2 volatilization, and the dehydration reaction of -O-Zr-O- with HO-PO-Al-OP- forms -O(-Zr-OPO -Al-OP)n-Porous membrane structure with moisture resistance. If the content of the zirconium salt is too low, that is, the weight ratio of the zirconium salt to the aluminum phosphate solution is less than 5:100, the formed film has poor moisture resistance.
該皮膜處理液更包含：一水性矽溶膠，且該水性矽溶膠與該磷酸鋁溶液的重量比為1：100至5：100。該皮膜處理液的黏度係數為50至200釐泊(CPS)。添加水性矽溶膠可以增加黏度，有利於皮膜處理液批覆於線材上，增加皮膜處理液的附著量。添加過量的水性矽溶膠將會使皮膜的抗濕性變差，例如該水性矽溶膠與該磷酸鋁溶液的重量比大於5：100時。The film treatment solution further includes: an aqueous silica sol, and the weight ratio of the aqueous silica sol to the aluminum phosphate solution is 1:100 to 5:100. The viscosity coefficient of the film treatment solution is 50 to 200 centipoise (CPS). The addition of water-based silica sol can increase the viscosity, which is conducive to the coating of the film treatment liquid on the wire and increase the adhesion amount of the film treatment liquid. Adding an excessive amount of water-based silica sol will worsen the moisture resistance of the film, for example, when the weight ratio of the water-based silica sol to the aluminum phosphate solution is greater than 5:100.
該皮膜處理液更包含：氮化硼，且該氮化硼與該磷酸鋁溶液的重量比為2：100至10：100。其中該氮化硼的一平均粒徑小於3微米。添加氮化硼可增進皮膜的潤滑性，但是添加過量，例如該氮化硼與該磷酸鋁溶液的重量比大於10：100時，可能會皮膜不易附著在盤元的外表面。The coating treatment solution further includes boron nitride, and the weight ratio of the boron nitride to the aluminum phosphate solution is 2:100 to 10:100. An average particle size of the boron nitride is less than 3 microns. The addition of boron nitride can improve the lubricity of the film, but excessive addition, for example, when the weight ratio of the boron nitride to the aluminum phosphate solution is greater than 10:100, the film may not easily adhere to the outer surface of the disk element.

Anyone who is familiar with this technique can make various modifications and modifications without departing from the spirit and scope of the present invention.
第一表 實驗例編號及組成
如第一表內容，其中比較例是採用習知的硫酸鹽溶液，其中硫酸鹽的重量百分比為18.6%。以實驗例C02的皮膜處理液來說明，表示了實驗例C02是以磷/鋁重量比為3.0/1.0的磷酸鋁溶液為基礎進行調配。實驗例C02還在每100g的磷酸鋁溶液添加了7g碳酸鋯鉀、5g水性矽溶膠及5g氮化硼及水，並且維持實驗例C02水的重量百分比約70%。其他實驗例的調配方法與實驗例C02相似，請參閱第一表。As shown in the first table, the comparative example uses a conventional sulfate solution, in which the weight percentage of sulfate is 18.6%. The film treatment solution of Experimental Example C02 is used to illustrate, which shows that Experimental Example C02 is formulated based on an aluminum phosphate solution with a phosphorus/aluminum weight ratio of 3.0/1.0. Experimental example CO 2 also added 7 g of potassium zirconium carbonate, 5 g of aqueous silica sol, 5 g of boron nitride and water per 100 g of aluminum phosphate solution, and maintained the weight percentage of experimental example CO 2 water at about 70%. The preparation method of other experimental examples is similar to experimental example C02, please refer to the first table.
第二表 各實驗例的特性評估
將實驗例及比較例塗佈在鈦鎳合金盤元的外表面之後，以80℃至150℃的溫度來烘乾鈦鎳合金盤元，在外表面上形成皮膜後進行各項測試。摩擦係數量測皮膜以及披覆抽線粉後的線材，是以Bowden-Leben type 摩擦係數測定儀進行量測。抗濕性測試是將線材放置於含水的密閉器皿中，計算測試前後重量差異百分比，計算方式為(吸濕塗覆皮膜線材重量-原塗覆皮膜線材重量)/皮膜處理重量 x100%，皮膜處理重量為(塗覆皮膜線材重-線材重)。測試結果分為3等，○：吸濕重量＜10%、△：10%~20%、X：＞50%。清洗性測試是將線材浸泡在50℃，0.5%的NaOH溶液中，兩分鐘後取出水洗，並且氣槍吹除後，量測洗除後重量百分比，計算方式為(原塗覆皮膜線材線材重量-洗後塗覆皮膜重量)/皮膜處理重量x100%，皮膜處理重量為(塗覆皮膜線材重-線材重)。附著性測試則是將線材膠帶完全覆蓋黏貼後，撕開膠帶，量測剝落重量百分比，計算方式為(黏剝後膠帶重量-黏剝前膠帶重量)/皮膜處理重量x100%，皮膜處理重量為(塗覆皮膜線材重-線材重)。After the experimental example and the comparative example were coated on the outer surface of the titanium-nickel alloy disc element, the titanium-nickel alloy disc element was dried at a temperature of 80°C to 150°C, and various tests were performed after forming a film on the outer surface. Coefficient of friction measurement The film and the wire coated with the drawing powder are measured with a Bowden-Leben type friction coefficient tester. The moisture resistance test is to place the wire in a closed container containing water and calculate the percentage of weight difference before and after the test. The calculation method is (weight of the moisture-absorbing coated wire-weight of the original coated wire)/film processing weight x 100%, film processing The weight is (the weight of the coated film wire-the weight of the wire). The test results are divided into 3 grades, ○: moisture absorption weight <10%, △: 10%-20%, X: >50%. The cleanability test is to immerse the wire in a 0.5% NaOH solution at 50°C, take it out for two minutes, and wash it off with an air gun, and measure the weight percentage after washing off. The calculation method is (the weight of the original coated film wire- Coating film weight after washing)/coating film processing weight x 100%, and film processing weight is (coating film wire weight-wire weight). The adhesion test is to completely cover the wire tape after sticking, tear off the tape, and measure the peeling weight percentage. The calculation method is (the weight of the tape after peeling-the weight of the tape before peeling)/film processing weight x 100%, and the film processing weight is (Coated film wire weight-wire weight).
由第二表比較可以得知，經過本發明多個實驗例的皮膜處理液處理後的鈦鎳合金線材的皮膜摩擦係數接近甚至優於比較例(習知技術)，而且再搭配抽線粉後都可以達到更小的摩擦係數，也就是更好的潤滑效果。而在抗濕性更是大幅優於比較例。此外，也與比較例一樣具備易清洗的特性。最後，附著性也是明顯優於比較例。It can be seen from the comparison of the second table that the coating friction coefficient of the titanium-nickel alloy wire treated with the coating treatment solution of multiple experimental examples of the present invention is close to or even better than that of the comparative example (conventional technology). Both can achieve a smaller coefficient of friction, that is, a better lubrication effect. The moisture resistance is much better than the comparative example. In addition, it is also easy to clean as in the comparative example. Finally, the adhesion is also significantly better than the comparative example.
如上所述，本發明提供了一種皮膜處理液，可以在抽線前於常溫下預先塗覆在鈦鎳合金盤元的外表面，進而形成附著性佳且抗吸濕性良好的皮膜。此外，本發明還提供了一種鈦鎳合金盤元的抽線預處理方法，以利於在鈦鎳合金盤元的外表面形成一皮膜。本發明之皮膜對抽線粉具有良好的附著性，可以增加抽線粉附著量，因而在抽線的過程中，可以保有良好的潤滑效果。此外，抽線後，鈦鎳合金線材的皮膜也具有容易清洗的特性。As described above, the present invention provides a coating treatment solution, which can be pre-coated on the outer surface of the titanium-nickel alloy disk element at room temperature before the wire is drawn, thereby forming a coating with good adhesion and moisture resistance. In addition, the present invention also provides a wire-drawing pretreatment method for the titanium-nickel alloy disc element to facilitate the formation of a film on the outer surface of the titanium-nickel alloy disc element. The film of the present invention has good adhesion to the thread drawing powder, and can increase the adhesion amount of the thread drawing powder, so that a good lubricating effect can be maintained during the thread drawing process. In addition, after the wire is drawn, the film of the titanium-nickel alloy wire also has the characteristics of easy cleaning.
雖然本發明已以較佳實施例揭露，然其並非用以限制本發明，任何熟習此項技藝之人士，在不脫離本發明之精神和範圍內，當可作各種更動與修飾，因此本發明之保護範圍當視後附之申請專利範圍所界定者為準。Although the present invention has been disclosed in preferred embodiments, it is not intended to limit the present invention.
