Description
本發明涉及一種表面處理遮蔽方法，尤其涉及一種在表面處理時對工件孔眼進行遮蔽之方法。 The present invention relates to a surface treatment masking method, and more particularly to a method of masking a workpiece aperture during surface treatment.
對工件表面處理時，如塗裝、烤漆、噴砂、電鍍、陽極氧化、電泳等，工件上開設之具有特定功能之孔眼並不需要進行上述處理，因此需在表面處理過程中將其遮蔽保護。目前常用之方法係採用保護膠套將孔眼堵塞，從而避免表面處理時之反應物進入孔眼。然，如孔眼結構較複雜時，保護膠套較難完全堵塞孔眼，或當孔眼較小時，保護膠套易脫落，保護效果不佳。 When the surface of the workpiece is treated, such as painting, baking, sand blasting, electroplating, anodizing, electrophoresis, etc., the hole with a specific function on the workpiece does not need to be treated as described above, so it needs to be shielded and protected during the surface treatment. At present, the commonly used method uses a protective rubber sleeve to block the pores, thereby avoiding the reactants entering the pores during surface treatment. However, if the structure of the hole is complicated, it is difficult to completely block the hole of the protective rubber sleeve, or when the hole is small, the protective rubber sleeve is easy to fall off, and the protection effect is not good.
鑒於上述狀況，有必要提供一種保護效果較佳之表面處理遮蔽方法。 In view of the above circumstances, it is necessary to provide a surface treatment masking method which is better in protection effect.
一種表面處理遮蔽方法，其包括以下步驟：調配塗料，該塗料耐表面處理，其包括樹脂及溶劑，該塗料之表面張力小於或等於22毫牛頓/米，該樹脂耐酸鹼腐蝕，該樹脂包括矽膠、矽橡膠、環氧樹脂、亞克力樹脂及聚氨酯中之一種或多種；及，固化塗料，以形成覆蓋該孔眼內壁之保護膜，以防止該孔眼內壁被表面處理。 A surface treatment masking method comprising the steps of: formulating a coating, the coating is resistant to surface treatment, comprising a resin and a solvent, the surface tension of the coating is less than or equal to 22 millinewtons per meter, the resin is resistant to acid and alkali corrosion, and the resin comprises One or more of silicone rubber, silicone rubber, epoxy resin, acrylic resin and polyurethane; and curing coating to form a protective film covering the inner wall of the hole to prevent the inner wall of the hole from being surface treated.
由於塗料之表面張力小於或等於22mN/m，塗料較易在孔眼之內壁 形成完整之保護膜，即使孔眼結構複雜，保護膜亦不易破裂，從而避免了採用膠塞保護時易導致之不能完全貼合孔眼內壁之問題。 Since the surface tension of the coating is less than or equal to 22 mN/m, the coating is easier to be on the inner wall of the hole. A complete protective film is formed, and even if the structure of the hole is complicated, the protective film is not easily broken, thereby avoiding the problem that the rubber plug is not easily adhered to the inner wall of the hole.

請參閱圖1，本發明實施方式之表面處理時保護工件孔眼之方法用於陽極氧化時保護工件10，工件10上開設有複數孔眼11。本發明實施方式之孔眼11包括不規則孔眼及螺紋孔，其縱向深度大致為0.1-15毫米(mm)，其橫向寬度大致為0.9-10mm。本發明實施方式採用之塗料包括樹脂、溶劑及添加劑，塗料之表面張力小於或等於22毫牛頓/米(mN/m)，塗料之固含量小於或等於30%。樹脂可為耐酸鹼腐蝕之樹脂，包括含氟樹脂、矽膠、矽橡膠、環氧樹脂、亞克力樹脂、聚氨酯或其中之一種或多種。上述列舉之樹脂一般會作改性處理，使改性後之樹脂含有氟官能基、碳氫脂肪族官能團或有機矽官能基，以降低其表面張力。溶劑可為常用之有機溶劑，如異構烷烴溶劑、甲苯、乙酸乙酯、丙酮、丁酮等。可理解，溶劑之成分並無特殊限制，只要能溶解上述樹脂，且不與陽極氧化之反應液反應即可。添加劑包括稀釋劑、固化劑、起始劑、增敏劑、黏著促進劑、分散劑、潤濕劑、增稠劑、消泡劑中或其中之一種或多種。可理解，添加劑亦可省略。 Referring to FIG. 1 , a method for protecting a workpiece hole during surface treatment according to an embodiment of the present invention is used to protect the workpiece 10 during anodization, and the workpiece 10 is provided with a plurality of holes 11 . The eyelet 11 of the embodiment of the present invention includes an irregular eyelet and a threaded hole having a longitudinal depth of approximately 0.1-15 millimeters (mm) and a lateral width of approximately 0.9-10 mm. The coating used in the embodiment of the invention comprises a resin, a solvent and an additive. The surface tension of the coating is less than or equal to 22 millinewtons per meter (mN/m), and the solid content of the coating is less than or equal to 30%. The resin may be an acid-base corrosion-resistant resin, including a fluorine-containing resin, silicone rubber, silicone rubber, epoxy resin, acrylic resin, polyurethane, or one or more of them. The above-exemplified resins are generally subjected to a modification treatment so that the modified resin contains a fluorine functional group, a hydrocarbon aliphatic functional group or an organic phosphonium functional group to lower the surface tension thereof. The solvent may be a commonly used organic solvent such as an isoparaffin solvent, toluene, ethyl acetate, acetone, methyl ethyl ketone or the like. It is understood that the composition of the solvent is not particularly limited as long as it can dissolve the above resin and does not react with the reaction solution for anodization. The additive includes a diluent, a curing agent, a starter, a sensitizer, an adhesion promoter, a dispersant, a wetting agent, a thickener, an antifoaming agent, or one or more of them. It will be appreciated that the additives may also be omitted.
本實施方式之表面處理時保護工件孔眼之方法中，首先，調配塗料，使塗料之表面張力小於或等於22mN/m；然後，塗料均勻塗布於孔眼11之內壁；最後，固化塗料，從而形成覆蓋孔眼11內壁之 保護膜30。固化塗料時依據塗料中所含樹脂之類型，可採用光固化或熱固化。在本發明實施方式中，保護膜30之厚度為0.1-5微米(μm)，如1μm，2μm或3μm。塗布方法可採用浸潤、刷塗、噴塗或淋塗等方式。保護膜30之厚度可藉由塗料之固含量來調節。 In the method for protecting the workpiece hole during the surface treatment of the embodiment, first, the coating material is formulated so that the surface tension of the coating material is less than or equal to 22 mN/m; then, the coating material is uniformly applied to the inner wall of the hole 11; finally, the coating is cured to form Covering the inner wall of the eyelet 11 Protective film 30. When curing the coating, depending on the type of resin contained in the coating, photocuring or thermal curing may be employed. In the embodiment of the present invention, the protective film 30 has a thickness of 0.1 to 5 μm, such as 1 μm, 2 μm or 3 μm. The coating method can be carried out by infiltration, brushing, spraying or shower coating. The thickness of the protective film 30 can be adjusted by the solid content of the coating.
由於塗料之表面張力小於或等於22mN/m，塗料較易在孔眼11之內壁形成完整之保護膜30，即使孔眼11結構複雜，保護膜30亦不易破裂，從而避免了採用膠塞保護易導致之不能完全貼合孔眼內壁之問題。即使當孔眼11較小時，保護膜30亦不會從孔眼11內壁脫離，避免了採用膠塞保護時易導致之膠塞脫落之問題。同時，由於保護膜30厚度較小，在孔眼11之尺寸偏差範圍內，表面處理後無需去除，從而簡化了生產流程，降低了生產成本。 Since the surface tension of the coating is less than or equal to 22 mN/m, the coating is more likely to form a complete protective film 30 on the inner wall of the hole 11. Even if the structure of the hole 11 is complicated, the protective film 30 is not easily broken, thereby avoiding the use of rubber stopper protection. It does not completely fit the problem of the inner wall of the eyelet. Even when the eyelet 11 is small, the protective film 30 is not detached from the inner wall of the eyelet 11, thereby avoiding the problem that the rubber plug is easily peeled off when the rubber stopper is used for protection. At the same time, since the thickness of the protective film 30 is small, within the range of dimensional deviation of the eyelet 11, there is no need to remove after the surface treatment, thereby simplifying the production process and reducing the production cost.
塗料實施例及對比例成分與性質列表列舉了3實施例及1對比例以具體說明本發明實施方式採用之塗料。 Coating Examples and Comparative Examples Components and Properties List 3 Examples and 1 Comparative Examples are used to specifically illustrate the coatings employed in the embodiments of the present invention.
可理解，當工件10進行塗裝、烤漆或噴砂等不涉及酸鹼反應液之表面處理時，樹脂亦可為非耐酸鹼腐蝕之樹脂，即樹脂相應於具體之表面處理方法而選擇，只要其耐相應之表面處理即可，如電鍍時，只要樹脂耐電鍍即可。 It can be understood that when the workpiece 10 is coated, painted or blasted, and the surface treatment of the acid-base reaction liquid is not involved, the resin may also be a non-acid and alkali resistant resin, that is, the resin is selected according to a specific surface treatment method, as long as It can withstand the corresponding surface treatment, such as plating, as long as the resin is resistant to electroplating.
