Description
【発明の詳細な説明】 ［産業上の利用分野］ 本発明は、帯電防止フッ素樹脂組成物に関ケる。[Detailed description of the invention] [Industrial application field] The present invention relates to antistatic fluororesin compositions.
［従来の技術］
フッ素樹脂は、優れた耐熱性、非粘着性及び耐薬品性な
どを有するので、食品工業及び半導体工業などにおいて
使用されている。しかし、フッ素樹脂は、電気絶縁性が
大きいので、非常に帯電しゃずいという性質を有する。[Prior Art] Fluororesins have excellent heat resistance, non-stick properties, chemical resistance, etc., and are therefore used in the food industry, semiconductor industry, and the like. However, since fluororesin has high electrical insulating properties, it has a property of being extremely resistant to charging.
したがって、フッ素樹脂の帯電を防止する方法として、
例えば種々の導電性充填剤、例えば、カーボンブラック
、金属粉末又は繊維状チタン酸カリウムなどをフッ素樹
脂に添加する方法か提案されている。しかし５、いずれ
の充填剤も満足な結果を与えない。Therefore, as a method to prevent electrification of fluororesin,
For example, methods have been proposed in which various conductive fillers, such as carbon black, metal powder, or fibrous potassium titanate, are added to fluororesins. However, 5, neither filler gives satisfactory results.
カーボンブラックは、フッ素樹脂に添加した場合には、
フッ素樹脂が黒色を呈し、フッ素樹脂に自由な着色がで
きない。また、フッ素樹脂が食品に接触する用途には使
用できない。When carbon black is added to fluororesin,
The fluororesin exhibits a black color, making it impossible to freely color the fluororesin. Furthermore, it cannot be used in applications where fluororesin comes into contact with food.
金属粉末は、フッ素樹脂に対する導電性効果が／ｊ＼さ
く、多量に添加する必要がある。したがって、フッ素樹
脂の機械的強度が低下する。The metal powder has a poor conductivity effect on the fluororesin, and therefore needs to be added in large amounts. Therefore, the mechanical strength of the fluororesin decreases.
繊維状チタン酸カリウム（例えば、住友化学株式会社製
、白色導電性フィラーＦＦ−２０２）は、白色導電性充
填剤である。しかし、繊維状チタン酸カリウムを添加し
たフッ素樹脂は、焼成などの高温に付した場合に、変色
する。Fibrous potassium titanate (for example, white conductive filler FF-202 manufactured by Sumitomo Chemical Co., Ltd.) is a white conductive filler. However, the fluororesin to which fibrous potassium titanate is added changes color when subjected to high temperatures such as firing.
［発明が解決しようとする課題］
本発明の目的は、良好な帯電防止性を有し、白色であり
、焼成後に変色せず、機械的強度が良好であるフッ素樹
脂組成物を提供することにある。[Problems to be Solved by the Invention] An object of the present invention is to provide a fluororesin composition that has good antistatic properties, is white, does not change color after firing, and has good mechanical strength. be.
［課題を解決するだめの手段］
本発明の要旨は、

The antistatic fluororesin composition consists of 25% by weight of zinc oxide, and (c) the remainder of the fluororesin.

６〜２５重量％、好ましくは８〜１５重量％である。The fibrous conductive titanium oxide (a) is a titanium oxide fiber whose surface is coated with a conductive substance such as conductive tin oxide. The fibrous conductive titanium oxide provides conductivity to the fluororesin composition. The fibrous conductive titanium oxide usually has a long sleeve length of ~50μl, preferably a 3~6μ shoulder length, a short axis length of 0.01~1μ degrees, preferably 0.05~0.1μ degrees, and an axial ratio (length axis/minor axis) is two or more. The amount of fibrous conductive titanium oxide is 6 to 25% by weight, preferably 8 to 15% by weight, based on the fluororesin composition.

成物にクラックが生じやすい。If the amount of fibrous conductive titanium oxide is less than 6% by weight, the fluororesin composition will not have a sufficient antistatic effect. When the amount is more than 25%, cracks are likely to occur in the fluororesin composition.

、酸化亜鉛の添加によって、導電性を損なわずに、白色
度が付与され、機械的特性、特に圧縮特性が向上する。When only fibrous conductive titanium oxide is added, the fluororesin composition becomes gray after firing and does not become white. However, by adding zinc oxide, whiteness is imparted without impairing conductivity, and mechanical properties are improved. Properties, especially compression properties, are improved.

It is 15% by weight. If the amount of zinc oxide is less than 0.1% by weight, sufficient whiteness cannot be obtained. When the amount is more than 25%, cracks are likely to occur in the fluororesin composition.
