Embodiment 1

[0017] An inorganic ceramic non-stick pan composite coating, which is composed of a primer coating and a layer of top coating, the primer coating is an inorganic ceramic coating, the thickness of the primer coating is 15 μm, and the thickness of the primer coating is 1.2 μm. roughness; the surface coating is an inorganic ceramic coating, the thickness of the surface coating is 3 μm, and the surface roughness is 0.6 μm. The manufacture method of this kind of inorganic ceramic non-stick pan composite coating is to use wet-on-wet process on the pretreated base material to successively spray the primer coating required for forming the primer coating and the formation of the surface coating. The desired surface coating is then baked and formed at a temperature of 180°C.

[0018] The primer coating is obtained by spraying the primer paint first, and then drying. The primer paint is prepared by mixing silane, silica sol, pigments and auxiliary agents. The silane is methyltrimethoxysi...

Embodiment 2

[0024] An inorganic ceramic non-stick composite coating, which is composed of a primer coating and a layer of top coating, the primer coating is an inorganic ceramic coating, the thickness of the primer coating is 50 μm, and the thickness of the primer coating is 3.5 μm roughness; the surface coating is an inorganic ceramic coating, the thickness of the surface coating is 10 μm, and the surface roughness is 1.2 μm. The manufacture method of this kind of inorganic ceramic non-stick pan composite coating is to use wet-on-wet process on the pretreated base material to successively spray the primer coating required for forming the primer coating and the formation of the surface coating. The desired surface coating is then baked and formed at a temperature of 200°C.

[0025] The primer coating is firstly sprayed with primer paint and then dried. The primer paint is prepared by mixing silane, silica sol, pigments and additives. The silane is methyltriethoxysilane , the proportionin...

Abstract

The invention discloses an inorganic ceramic non-stick pan composite coating and a manufacturing method thereof. The inorganic ceramic non-stick pan composite coating is prepared from a bottom coatingand a surface coating, wherein the bottom coating is an inorganic ceramic coating which is 15 to 50 mum in thickness, is more than or equal to 1.2 and is less than or equal to 3.5 mum in roughness Ra; the surface coating is an inorganic ceramic coating which is 3 to 10 mum in thickness, and is more than or equal to 0.6 and is less than 1.2 mum in roughness Ra. By adopting the inorganic ceramic non-stick pan composite coating, the long-effect non-stick property of the non-stick pan is improved effectively. In particular, when the surface film is slightly damaged, high non-stick property can bekept.

Description

technical field [0001] The invention relates to an inorganic ceramic composite coating with a non-stick effect on metal surfaces, in particular to an inorganic ceramic non-stick composite coating suitable for coating the surface of cooking utensils. Background technique [0002] At present, non-stick pan coatings are basically divided into two categories, one is water-based non-stick fluorocarbon coatings, which are mainly provided by PTEE, and the other is inorganic ceramic coatings that have only emerged in recent years. [0003] Water-based non-stick fluorocarbon coating, commonly known as "Teflon", has very good non-stick properties, but its disadvantages are that its hardness is not high, and its wear resistance is not good. At the same time, it was later found that PTEE may cause cancer, so inorganic ceramic coatings are used instead pregnancy. The existing inorganic ceramic non-stick pan coating is to spray a layer of non-stick ceramic paint on the pretreated metal...
