Description
【発明の詳細な説明】 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 painting resin products.
従来、樹脂製品に部分塗装を施す場合には、治具を使用

修正工数が増加する等の問題があり、又、後者において
は、貼り付は工数が多いため煩しく、かつ、曲線部分の
見切線の貼υ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
問題があった。Conventionally, when applying partial painting to resin products, it was necessary to use a jig to cover the unpainted parts or to use masking tape to cover the unpainted parts; In the case of products with complex shapes, where it is difficult to seal the cutting lines, complete coverage cannot be achieved.
There are problems such as increased man-hours for corrections, and in the latter case, pasting is troublesome because it requires a lot of man-hours, and pasting of parting lines on curved parts is difficult and requires skill. However, since lifting of the tape could not be completely suppressed, there was a problem in that when the tape was removed, the paint on the area would also come 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って、部分塗装する部分がど
のような形状であっても容易に前処理をすることができ
、しかも、見切線部分の塗装が剥れることのない樹脂製
品の部分塗装方法を提供することを目的とするものであ
る。Therefore, the present invention has been made in order to solve the above-mentioned problems of the conventional art.No matter what shape the part to be partially painted has, it can be easily pretreated, and 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って説明する。The present invention will be described below with reference to illustrative embodiments.
先ず、樹脂製品aの塗装表面となる側の型、実施例の場
合下型11にシリコン等の離型剤12を塗布し、その上
から下記の配合組成からなるストリッパブルペイント1
3を全面に塗布し、乾燥させる。(第1図(イ)、(ロ
)参照)次に、表面に上記と同様の離型剤を塗布した上
型14を重合させ、樹脂を注入し、成形加工する。(第
1図(ハ)参照)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 1 having the following composition is applied on top of the mold release agent 12.
Apply 3 to the entire surface and let dry. (See FIGS. 1(a) and 1(b)) 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 FIG. 1(c)) Although a thermosetting resin is used as the resin material, it is preferable to use a reinforced thermosetting resin when baking painting is performed.
又、樹脂製品aの成形加工後(離型後)ストリッパブル
ペイントを更に塗布(アフターコート)することによっ
て、該ストリッ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。Further, by further applying (after-coating) the strippable paint after molding the resin product a (after releasing the mold), 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の塗装部分に覆

剥離する際に離型剤12も剥離できるため、従来性なわ
れていた離型剤12を取るだめの脱脂作業を省略するこ
とができる。After the strippable paint 13 covered with the painted part of the resin product a molded as described above is dried, it is cut by an appropriate means and peeled off to form the painted surface part 16. (See Figure 1) and (E)) After that, the painted surface part 16 is coated, dried, and baked if necessary, and then the strippable paint 13 is applied to other parts. Peel off and complete the resin product af: (Figure 1(f),
(See (g)) Note that since the mold release agent 12 can also be peeled off when the above-mentioned strippable pane 13 is peeled off, the conventional degreasing operation to remove the mold release agent 12 can be omitted.
又、上記塗装置5を施す際、ストリッパブルペイント1
3を塗布した部分を含む樹脂製品aの全面に塗布しても

It may be applied to the entire surface of the resin product a, including the part coated with No. 3, or it may be applied to an extent that slightly protrudes from the part to be painted. If the paint is applied to the entire surface of the resin product a, the paint will be wasted, but baking may occur due to the primer layer, enamel layer, and clear coat layer, which protects the strippable paint 13 from heat and prevents the plasticizer from splashing. Since this prevents the film from becoming hard, the peelability of the strippable paint 13 after baking is improved.

After applying the strippable paint and letting it dry, we cut and peeled off the strippable paint on the painted area, painted the core part, and then peeled off the strippable paint on other parts, so it was not complicated. The parting line can be easily and reliably drawn even on products with a shape, reducing the number of corrections required. Also, the parting line on curved parts does not come up like with conventional tape, so it is easy to Since the paint does not peel off, we were able to improve the accuracy of the painting.
