してきた。2. Description of the Related Art Conventionally, fluorine-based resins such as tetrafluoroethylene and tetrafluoroethylene-hexafluoropyropyrene copolymer have been used for cooking surfaces of heating cookers such as hot plates. This fluorine-based resin is highly non-adhesive, and has excellent chemical and heat resistance, so its major characteristics are that it has good release properties between food and the cooking surface during cooking, and is easy to clean. It has become rapidly popular in recent years.

傷ついて非常にきた力・くなり、被粘着性、耐食性が低
下してくる。One method is to roughen the surface of an aluminum alloy using plasting, then coat the surface with ceramic particles using a method such as plasma spraying to harden the surface of the aluminum alloy. There is a method of coating the aluminum alloy with a resin, or a method of roughening the surface of the aluminum alloy by etching, hardening the surface by anodizing, and coating the surface with a fluorine-based resin. According to these methods, even if the fluorine-based resin is scratched with a metal spatula, it is difficult to reach the aluminum alloy fabric, so corrosion resistance is improved compared to those without hardening treatment, but the hardness of the fluorine-based resin is Since the cooking surface is not raised high enough, the cooking surface will be damaged and become very hard and strong, resulting in a decrease in stickiness and corrosion resistance.

また、チタンコーティングマイカはリン片状で粒径が大
きく、添加量を増加すると被粘着性に問題が出てくる。In addition, titanium-coated mica is scale-like and has a large particle size, and if the amount added is increased, a problem arises in stickiness.

When a fluorine-based resin coating layer containing K2O・e'rio coating is provided, the surface of the sprayed layer is dotted with ceramic particles with a low melting point and ceramic particles with a high melting point in the matrix2, and the ceramic particles with a low melting point are sufficiently Since it is melted, it forms four parts from a macroscopic perspective, while ceramic particles with a high melting point are in a semi-molten state, so they form convex parts.

形状に改質することができる。Therefore, the intervals between the concave and convex portions vary depending on the mixing ratio of ceramic particles with a low melting point and ceramic particles with a high melting point, but the concave and convex portions are arranged regularly. By taking advantage of the characteristics of ceramic particles having different melting points and controlling the mixing ratio of two particle sizes, the surface of the ceramic sprayed layer can be modified into a desired shape.

Due to the additive effect of the rio process, the abrasion resistance of the fluororesin coating layer is dramatically improved.

に目立ちやすい欠点がある。K2O・eTio process reduces potassium hexatitanate whiskers (hereinafter referred to as 2o・6Ti○2) at a temperature of 600℃ to 1000℃ in an atmosphere containing reducing gases such as propane, butane, and city gas. Manufactured through processing. In addition, 20・ is the source of 2O−eTiOx.
eTio2 has an average fiber length of 10 to 20 μm and a fiber diameter of 0.
．． It is a white needle-like crystal with a size of 2 to 0.0 S μm, but in this case, the fibers are entangled with each other, giving it a cotton-like appearance. When this is added to an aqueous dispersion of a fluororesin, there are problems with poor dispersibility, such as the formation of fiber clumps in some areas. Furthermore, because the color is white, the film formed on the cooking surface of the cooking container becomes whitish, and if you repeatedly cook yakiniku etc., it will quickly turn black in some areas, making stains very noticeable. There is.

1.26 is dark brown, and 1.26 is light brown, and is colored. Therefore, even if added to an aqueous dispersion of a fluorine-based resin, it will not become solid (1. Also, in the process of reduction treatment, long fibers break down and become short, so the length of the fibers is reduced. As a result, when added to an aqueous dispersion of fluorocarbon resin, it is uniformly dispersed, and the fluorocarbon resin coating is strengthened by the fine particles of 20·eTio.
The smoothness, abrasion resistance, anti-scratch property, coloring property, and corrosion resistance of the coating surface are greatly improved.

Since the fluorine-based resin remains in the four parts, the deterioration in stickiness is extremely small, and therefore the life characteristics are greatly improved.

It is possible to add up to 1 wt, but preferably the addition should be limited to 1 to 30w1%. If the amount of K2O or θTiO added exceeds 30 Wt, the hardness of the fluororesin coating layer 4 will increase, but the coating strength and tack resistance will decrease, and the surface smoothness will be impaired.

After drying at 120℃ for 10 minutes,
A sample of an example of the present invention was prepared by baking at 80° C. for 10 minutes 17 and then water-cooling and curing at 330° C. The measurement was carried out using gray alumina cA7203eel and Tie as conventional examples.
22.5s) A fluorine-based resin coating layer not containing 20.TiO was provided on the single thermal sprayed layer via a primer layer, which was simultaneously prepared and compared with the conventional example. The result was his second daughter, Toushi.
