物に関する。Detailed Description of the Invention [Industrial Field of Application] The present invention relates to a composition for coating a fluororesin, and more specifically, the present invention relates to a composition for coating a fluororesin, and more specifically, a composition containing polyether sulfone (hereinafter referred to as P) in addition to a fluororesin.
It's called ES. ) The present invention relates to a fluororesin coating composition containing rL.
［従来技術］
フッ素樹脂は、潤滑性があり、しかも耐熱性があるため
、各種基材の表面に塗布されて用いられている。[Prior Art] Fluororesins have lubricating properties and heat resistance, so they are used by being coated on the surfaces of various base materials.

しなければならないことが分かった。Coating compositions containing PES particles blended with fluororesin are also used as coating compositions for substrates, but in order to finish the surface of the coating film smoothly, the particle size of the PES particles must be 5μ or less. That's what I found out.

ミリングして粒径１４．５μのＰＥＳ粉末を得ている。For example, Japanese Patent Publication No. 53-34134 discloses the relationship between the molecular weight of PES, milling time, and PES particle size. In addition, in Japanese Patent Publication No. 55-44785,
A method for obtaining an aqueous dispersion by processing PES powder and water using a ball mill is disclosed. Tokuko Sho 55-8351
The publication describes a method of ball milling PES powder or particles with water in the presence of an emulsifier or a method of obtaining PES powder by precipitation from a solution, preferably a dilute solution, specifically by e.g. 550μ PE
The S powder was pre-pulverized to a powder of 54.5μ, to which Triton X100 was added and milled with a ceramic ball for 178 hours to obtain a PES powder with a particle size of 14.5μ.
しかしながら、これら方法で得られるＰＥＳ粒子の粒径
は２５μより小さいけれども５μより大きいものであり
、これ上り粒径の小さいものは実用的でないとされてき
た（特公昭５３−３４１３４号公報参照）。However, the particle size of PES particles obtained by these methods is smaller than 25 μm but larger than 5 μm, and it has been said that particles with a particle size this small are not practical (see Japanese Patent Publication No. 34134/1983).
しかし、先に述べたように、本発明者らの研究によれば
、塗膜の表面を平滑に仕上げるためにはＰＥＳ粒子の粒
径を従来の知見に反して５μ以下にしなければならない
のである。However, as mentioned earlier, according to the research conducted by the present inventors, in order to finish the surface of the coating film smoothly, the particle size of the PES particles must be reduced to 5μ or less, contrary to conventional knowledge. .

たものである。Needless to say, a smooth coating surface is necessary, for example, when using fluororesin-coated objects as cooking utensils, so that dirt will not settle on them, and even if they do, they can be easily cleaned. It is. Therefore, the particle size of the PES particles added to the fluororesin coating composition needs to be 5 μm or less, and preferably about 2 to 3 μm. FIG. 1 shows this. Figure 1 shows the surface roughness of 91m prepared by using an aqueous dispersion paint obtained by mixing a PES aqueous dispersion with a polytetrafluoroethylene aqueous dispersion by the method described in Example 1 below. degree, using I) E
This is a graph showing the results of measurement with various particle sizes of S particles.

めには、表面粗度が約３〜３５μ以下であることが必要
であり、このことは、換言すれば、十分な非粘着性をう
るためにはＰＥＳ粒径が５μ以下でなければならないこ
とを意味する。As shown in Figure 1, the PES particle size and surface roughness have a nearly proportional relationship, and a PES particle size of 5 μ is approximately 3 μm in surface roughness.
Corresponds to ~35μ. On the other hand, in order to obtain sufficient non-adhesive properties of the coating film, it is necessary that the surface roughness is approximately 3 to 35μ or less. This means that the PES particle size must be less than or equal to 5μ.

。On the other hand, however, it is difficult to pulverize PES to a size of 5 microns or less using the above-mentioned known methods, and in fact, none of these methods has achieved this. For example, these methods require relatively short milling times for low molecular weight PES and particle sizes of approximately IO
A material with a high molecular weight of about 15 microns can be obtained even after milling for a considerable period of time.

用組成物に配合することにより完成されたものである。As a result of repeated research to develop a method for obtaining an aqueous dispersion containing PES with a particle size of 5 μ or less in a short time, the present inventor found that
When an aqueous dispersion of PES powder is ground by applying high shear force in the presence of a specific solvent, the rl diameter of PES powder can easily be reduced to 5μ.
We found the following. The present invention was completed by blending the thus obtained PES particles with a particle size of 5 μm or less into a composition for covering fluorine and fat.
