(産業上の利用分野)
本発明はポリフェニレンオキサイド(PPO)樹脂への
塗装方法に関するものである。DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a method for coating polyphenylene oxide (PPO) resin.
(従来の技術)
ppo樹脂は機械的強度、電気的特性、耐熱性、耐水性

し電気、通信分野等広範囲の用途に用いられている。こ
のようなPPO樹脂に塗装を施す場合には、通常次に示
す塗料が用いられている。(Prior Art) PPO resin has excellent properties such as mechanical strength, electrical properties, heat resistance, and water resistance, so it is used in a wide range of applications including the automobile field, electricity, and communication fields. When painting such PPO resin, the following paints are usually used.
i)溶剤蒸発型塗料
有機溶剤が蒸発するだけで塗膜を形成する塗料で、この
ために樹脂自体は初めから分子量の相当高いものが用い
られている。i) Solvent evaporation type paint A paint that forms a coating film simply by evaporation of an organic solvent, and for this reason, the resin itself used has a fairly high molecular weight from the beginning.
1i)2液エポキシ塗料

添加するものである。1i) Two-component epoxy paint In order to exhibit the curing function of epoxy resin (resin with two or more epoxy groups in each molecule), amine,
A substance containing active hydrogen, such as polyamide resin, is added immediately before use.

り、塗装工程が増加するという問8点がある。(Problems to be Solved by the Invention) However, in the method of coating PPO resin using the above-mentioned solvent evaporation paint and two-component epoxy paint, in the case of a solvent evaporation paint, the paint has chemical resistance and scratch resistance. Because of its poor durability and weather resistance, it cannot be used when these properties are required. In addition, two-component epoxy paints also have poor weather resistance, so when severe performance is required, such as in automobile exterior parts, it is necessary to apply an additional top coat, which increases the number of painting steps.
(問題点を解決するための手段)
本発明者は、上記問題点を解決すべく種々研究の結果、

れることを確かめた。(Means for Solving the Problems) As a result of various studies to solve the above problems, the present inventor has found that
Hydroxyl value 20-60KO) 1■/g, molecule M3゜500
~5,000 polyols and isocyanates2
Polyphenylene oxide (PPO) liquid urethane paint
When coating a resin surface, it was confirmed that the adhesion between the coating film and the PPO resin was extremely good and the above problems were solved.
(作 用)
上記2液ウレタン塗料において、ポリオールの水酸基価
が20より小さくなると塗料の粘着性、耐溶剤性が悪(
なり、一方60を越えるとppo樹脂素材との密着性が
低下して好ましくない。(Function) In the above two-component urethane paint, if the hydroxyl value of the polyol is less than 20, the adhesiveness and solvent resistance of the paint will be poor (
On the other hand, if it exceeds 60, the adhesion to the PPO resin material decreases, which is not preferable.
またポリオールの分子量が3.500より小さくなると
粘着性が生じ、5,000を越えると塗装作業性が悪く
なり好ましくない。Moreover, if the molecular weight of the polyol is less than 3.500, stickiness will occur, and if it exceeds 5,000, coating workability will deteriorate, which is not preferable.
上記ポリオールとしては27〜30重量%の無水フタル
酸を含むポリエステル樹脂を用いるのが好ましい。無水
フタル酸を27〜30重量%とするのは速乾性をもたせ
、PPO素材に密着性のよいラーカータイプに近づける
ためである。As the polyol, it is preferable to use a polyester resin containing 27 to 30% by weight of phthalic anhydride. The reason why the phthalic anhydride content is 27 to 30% by weight is to provide quick-drying properties and to approximate a lurker type with good adhesion to the PPO material.
