本発明は樹脂製品の部分塗装方法に関するもの
である。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for partially coating resin products.
従来、樹脂製品の部分塗装を施す場合には、治
具を使用して塗装しない部分を覆うか、あるい
は、マスキングテープを使用して塗装しない部分
を覆うかしていたが、前者においては、見切線の
シールが難かしく、複雑な形状の製品の場合は、
完全に被覆することができないため、修正工数が
増加する等の問題があり、又、後者においては、
貼り付け工数が多いため煩しく、かつ、曲線部分
の見切線の粘り付けが困難で熟練度を必要とする
だけではなく、テープの浮きを完全に抑えきれな
いために、該テープを剥がすと、該部分の塗装も
剥がれてしまうという問題があつた。 Conventionally, when painting parts of resin products, a jig was used to cover the parts not to be painted, or masking tape was used to cover the parts not to be painted. For products with complicated shapes where it is difficult to seal the cutting lines,
Since complete coverage is not possible, there are problems such as increased repair man-hours, and in the latter case,
Not only is it cumbersome because it requires a lot of work, and it is difficult to stick parting lines on curved parts and requires great skill, but it is not possible to completely prevent the tape from lifting, so when the tape is removed, There was also the problem that the paint on the area would peel off.
そこで本発明は上記従来の問題点に鑑みてこれ
を解消するためになされたものであつて、部分塗
装する部分がどのような形状であつても容易に前
処理をすることができ、しかも、見切線部分の塗

提供することを目的とするものである。 The present invention has been developed in view of the above-mentioned problems of the conventional art, and it is possible to easily pre-treat the part to be partially painted, regardless of its shape. It is an object of the present invention to provide a partial coating method for a resin product in which the coating on the parting line portion does not peel off.
以下、本発明を図示せる実施例に随つて説明す
る。 The present invention will be described below with reference to illustrative embodiments.

尚、該樹脂材には熱硬化性樹脂を使用するが、
焼付塗装をする場合には強化熱硬化性樹脂を使用
する方が好ましい。 First, a mold release agent 12 such as silicone is applied to the mold on the side that will be the painted surface of the resin product a, the lower mold 11 in the case of the example, and then a strippable paint 13 having the following composition is applied over the entire surface. Apply and let dry. (See Figures 1A and 1B) Next, the upper mold 14 whose surface is coated with the same mold release agent as above is polymerized, resin is injected, and molded. (See Figure 1 C) Note that thermosetting resin is used as the resin material, but
In the case of baking painting, it is preferable to use a reinforced thermosetting resin.
又、樹脂製品ａの成形加工後（離型後）ストリ
ツパブルペイントを更に塗布（アフターコート）
することによつて、該ストリツパブルペイントの
膜厚及び膜強度を上げることができる。 In addition, after the molding process of resin product a (after mold release), strippable paint is further applied (after coat).
By doing so, the film thickness and film strength of the strippable paint can be increased.
上記のようにして成形された樹脂製品ａを型か

尚、上記ストリツパブルペイント１３を剥離す

れていた離型剤１２を取るための脱脂作業を省略
することができる。 After removing the resin product a molded as described above from the mold and drying the strippable paint 13 covered with the painted part of the resin product a, the resin product a is removed by an appropriate means. The strippable paint 13 at the painting parting line part is cut, and the strippable paint 13 on the side to be painted is peeled off to form a painted surface part 16. (See Figure 1 D and H)
After that, after painting 15 the above-mentioned painted surface portion 16,
After drying and baking if necessary, the strippable paint 13 on other parts is peeled off to complete the resin product a. (See Figures 1F and 1F) Furthermore, since the mold release agent 12 can also be peeled off when the strippable paint 13 is peeled off, the conventional degreasing work to remove the mold release agent 12 can be omitted. I can do it.

リツパブルペイント１３の剥離性が向上する。 Further, when applying the coating 15, it may be applied to the entire surface of the resin product a including the area where the strippable paint 13 has been applied, or it may be applied to an extent that slightly protrudes from the area to be painted. If the paint is applied to the entire surface of the resin product a, the paint will be wasted, but the primer layer, enamel layer, and clear layer of the paint will protect the strippable paint 13 from heat during baking, so the plasticizer will not be used. Since skipping is suppressed and the film is prevented from becoming hard, the removability of the strippable paint 13 after baking is improved.

た。Example composition of strippable paint 1 Vinyl acetate 30% Toluene 50% Stabilizer 20% Example 2 Vinyl acetate 40% Methyl ethyl ketone 50% Stabilizer 20% Example 3 Vinyl acetate 35% Methyl butyl ketone 50% Stabilizer 15% Example 4 Vinyl chloride 40% Toluene 50% Stabilizer 10% Example 5 Vinyl chloride 35% Methyl ethyl ketone 50% Stabilizer 15% Example 6 Vinyl chloride 30% Methyl butyl ketone 50% Stabilizer 20% As described above, according to the present invention , After applying strippable paint to the surface of the resin product and letting it dry, cut the strippable paint at the paint separation line of the resin product, peel off the strippable paint on the side to be painted, and remove the strippable paint from the painted surface. This method allows the strippable paint to be peeled off from other parts after forming a part and painting that part, so that parting lines can be easily and reliably drawn even on products with complex shapes. It can reduce the number of correction steps,
Furthermore, since the parting line of the curved part does not come up unlike conventional tapes, the coating on this part does not peel off, so it is possible to improve the painting accuracy.

向上する等の効果を有するものである。 Furthermore, according to the present invention, when stripping the strippable paint, a mold release agent such as silicone can also be removed, so the conventional degreasing process for removing the mold release agent can be omitted. Since there is no need to install any equipment or devices for this purpose, not only is the equipment cost reduced, but since the painted surface is directly exposed, impurities such as dirt, dust, and moisture do not intervene, resulting in a fresh painted surface. It becomes possible to paint the surface area, which has the effect of improving the adhesion of the paint and improving the quality of the paint.
