Problems solved by technology

[0010] However, in the case of the cooking utensil manufactured by the above conventional technique, since ethylene-tetrafluoroethylene copolymer (ETFE) having relatively low heat resistance among fluororesins is laminated on the metal base, there is the following problem , that is, the heat resistance required in cooking utensils cannot be sufficiently satisfied, and the non-stick property and durability cannot be sufficiently satisfied at the same time

Embodiment 1

[0041]First, a multilayer polytetrafluoroethylene (PTFE) film having a thickness deviation of 1.3 μm and a surface roughness of 0.65 μm was formed by a casting method.

[0042] Meanwhile, the surface of the plate-like metal substrate 1 was pretreated, and then a polytetrafluoroethylene (PTFE) film was laminated on the pretreated surface of the metal substrate 1 to prepare a laminate.

[0043] Next, the laminated body was cut into a circular shape, and then shaped into a cookware form, and the shaped cookware was subjected to an outer surface treatment to manufacture a cookware main body A.

[0044] Thereafter, the cookware handle B is attached to the cookware body A manufactured as described above to manufacture the figure 1 The cooking utensil (frying pan) shown in .

[0045] The thickness variation, surface roughness, and number of times allowed to fry eggs of the fluororesin film formed on the inner bottom surface of the manufactured cooking utensil (frying pan) were measu...

Embodiment 2

[0048] First, a polytetrafluoroethylene (PTFE) film having a thickness deviation of 4 μm and a surface roughness of 1.6 μm was formed by a dicing method.

[0049] Meanwhile, the surface of the plate-like metal base 1 was pretreated, then cut into a circular shape, and then polytetrafluoroethylene (PTFE) was laminated thereto to prepare a laminate.

[0050] Next, the laminate is formed into a cooker, and the shaped cooker is subjected to an outer surface treatment to manufacture a cooker body A.

[0051] Thereafter, the cookware handle B is attached to the cookware body A manufactured as described above to manufacture the figure 1 The cooking utensil (frying pan) shown in .

[0052] The thickness variation, surface roughness, and number of times allowed to fry eggs of the fluororesin film formed on the inner bottom surface of the manufactured cooking utensil (frying pan) were measured by the following evaluation methods, and the results are listed in Table 1 below.

Abstract

A cooking utensil according to the present invention comprises a cooking utensil body (A), which is configured as a laminate comprising a metal substrate (1) and a fluorine resin film (2) laminated on the metal substrate (1), the fluorine resin film (2) constituting the inner surface of the cooking utensil body (A), wherein the fluorine resin film (2) has a thickness deviation of 0.1-10[mu]m and a surface roughness of 0.1-10[mu]m. The fluorine resin film (2) is manufactured by a casting method, a cutting method, a calendar method, or an extrusion molding method, and therefore has uniform thickness and surface roughness. According to the present invention, the fluorine resin film (2) has uniform thickness and surface roughness, thereby improving non-stick characteristics. In addition, according to the present invention, the thickness of the fluorine resin film (2) can be easily formed even at a level of 20-300[mu]m. Compared with conventional methods of spraying a fluorine resin coating liquid in a liquid state, the present invention can resolve environmental problems resulting from scattering of the fluorine resin coating liquid, and can prevent degradation of non-stick characteristics due to poor coating of pinholes, for example.

Description

technical field [0001] The present invention relates to a cooking utensil with improved non-stick properties (cooking utensil, cooking utensil) and a method for making the same, and more particularly, to a cooking utensil with improved non-stick properties and a method for making Its method, the cooking utensil includes a cooking utensil body (cooking utensil body) constituted by a laminated body, in the laminated body, a fluorine resin film (fluorine resin film) layer having a uniform thickness and surface roughness Pressed on a metal substrate, thereby effectively preventing the phenomenon that food becomes sticky or adhered after cooking and scorched to the fluororesin film disposed on the inner surface of the cooking utensil. Background technique [0002] As a conventional technique for imparting non-stick properties to the inner surface of the cookware main body in order to prevent food from sticking to the inner surface of the cookware main body after cooking, a techni...
