Abstract

A thermal spray non-stick pan comprising a substrate layer, an outer paint layer, a spray layer, a primer layer, and a lacquer layer. The shape of the substrate layer defines the basic shape of the thermal spray non-stick pan. The outer lacquer layer is applied to the outer side of the substrate layer. The spray coating is sprayed on the inner side of the substrate layer. The primer layer is applied to the side of the melted layer opposite to one of the substrate layers. The topcoat layer is applied to the primer layer opposite to one side of the meltblown layer. By adding the spray layer, a protective layer may be formed between the primer layer and the substrate layer, so that when the topcoat layer and the primer layer are scratched by the spatula, scratches are generated. Or when the crack occurs, the external food soup water is still blocked by the molten layer without affecting the substrate layer, or the molten layer can provide the substrate when the pan is subjected to a large impact or scratch. The layer has a certain buffer protection effect, so the durability and service life of the pot can be improved.

When the material of the layer 3 is aluminum, the material of the molten layer 5 is preferably stainless steel. The spray layer 5 is sprayed on the inner side surface of the base material layer 3 by using a thermal spray (also known as thermal spray or thermal spray welding) coating technology, and the technical feature is that relative use can be used. The thick film made at the lower temperature for welding or smelting has less restrictions on the shape and size of the outer surface of the substrate layer 3, and has a higher degree of automation, and can achieve a more even and flat coating effect, and further, Since the surface of the substrate layer 3 is cooled during the spraying process (for example, using blow air cooling), the surface temperature of the substrate layer 3 can be maintained at a relatively low temperature, and the substrate layer 3 can be controlled before and after construction. Problems with distortion, deformation and metallurgical degradation occur.

The primer layer 6 is coated on the side of the spray layer 5 opposite to the substrate layer 3. The primer layer 6 is made of a non-stick coating such as fluororesin.

The topcoat layer 7 is applied to the primer layer 6 opposite to one side of the spray layer 5. The topcoat layer 7 is also made of a non-stick coating such as a fluororesin.

When the thermal spray non-stick pan 2 is produced, it is preferably carried out in the following manufacturing process:

1. Forming roughening: the substrate material 3 is formed by spin-molding the selected material into the basic shape of the pan 2, and then, in order to improve the bonding strength with the subsequent coating, the substrate layer 3 is formed. The inner surface is roughened.

2. Spray Spraying: The material of the selected spray layer 5 is sprayed on the inner side of the base material layer 3 by a thermal spray coating technique to form the sprayed layer 5.

3. Primer Process: The material of the primer layer 6 selected for use is applied to the inner side of the substrate layer 3, and dried to form the primer layer 6.

Fourth, the topcoat process: after cooling the current semi-finished product to room temperature, the material of the topcoat layer 7 selected for use is applied to the primer layer 6 opposite to one side of the sprayed layer 5 to form the topcoat Layer 7.

5. Sintering cooling: The current semi-finished product is sintered at a high temperature (for example, 400 ° C), and then cooled to a normal temperature.

6. External paint process: The outer surface of the base material layer 3 is roughened, and the material of the outer paint layer 4 selected for use is coated to form the outer paint layer 4.

7. Sintering and cooling again: The current semi-finished product is again sintered at a high temperature (for example, 320 ° C), and then cooled to normal temperature.

8. Assembly: At this time, the main body of the pot 2 has been completed, and can be assembled with other accessories (for example, various handles 8) to complete the thermal spray non-stick pot 2.

Through the above description, the advantages of this embodiment can be summarized as follows:

1. By adding the molten layer 5 disposed on the inner side of the substrate layer 3, a protective layer may be formed between the primer layer 6 and the substrate layer 3 to improve the protection of the substrate layer 3. The effect is that when the topcoat layer 7 and the primer layer 6 are scratched or cracked by the collision of the spatula, the external food soup water is still blocked by the molten layer 5 without affecting the base. The material layer 3, or when the pot 2 is subjected to a large impact or scratch, the spray layer 5 can also provide a certain cushioning protection effect of the base material layer 3, thereby improving the durability of the pot 2 Degree and service life.

2. By using the stainless steel or aluminum to form the molten layer 5, the anti-rust effect of the pot 2 can be increased, so that the durability and service life of the pot 2 can be further improved.

Referring to FIG. 3, a second embodiment of the thermal spray non-stick pan 2 of the present invention is similar to the first embodiment. The second embodiment differs from the first embodiment in that:
