Problems solved by technology

[0004] But the above-mentioned non-stick pan of stainless steel or composite steel also has defects. Compared with the current polytetrafluoroethylene coating, the non-stick performance of the cermet oxide film is not an order of magnitude, but slightly better than stainless steel. At the same time, the production cost of this process by electroplating is also relatively high, and the electroplating solution is likely to cause serious pollution to the environment

Embodiment 1

[0035] Such as figure 1 and figure 2 As shown, the method includes the following steps:

[0036] a. Surface pattern treatment: form concave-convex pattern 2 on the surface of the stainless steel plate by chemical etching or engraving or rolling; engraving in step a includes cutting engraving and laser engraving. For the production of concave-convex pattern 2, machining is also a method, which can be used in a wide range. Laser engraving can produce more precise patterns.

[0037] Specifically, the chemical etching in step a includes the following procedures: a1. Pretreatment: cleaning and drying the stainless steel plate; a2. Printing pattern: printing an ink pattern in a predetermined area on the surface of the stainless steel plate by screen printing ; a3, drying: put the stainless steel plate printed with the ink pattern into an oven for baking, so that the ink is dried and tightly combined on the surface of the stainless steel plate; the baking temperature in the proces...

Embodiment 2

[0045] The general content of this embodiment is the same as that of Embodiment 1, the difference is that in this embodiment, as another solution, such as image 3 As shown, the chemical etching in step a includes the following procedures: a11, pretreatment: cleaning and drying the stainless steel plate; a12, spraying photosensitive ink: uniformly coating photosensitive ink on the stainless steel surface, and then preheating and drying; a13, exposing : Use a high-pressure mercury lamp or a metal halide lamp to expose the photosensitive ink on the stainless steel surface under the film negative of the preset pattern; a14, developing: use sodium carbonate solution to develop the ink on the stainless steel surface after being photosensitive; a15, strong curing: Put the stainless steel plate into the oven for baking and curing. This method of forming patterns by exposing photosensitive inks is relatively simple and easy to operate, and can form complex concave-convex patterns with...

Abstract

The invention provides a method for manufacturing a stainless steel or compound steel non-stick pan and belongs to the technical field of non-stick pan manufacturing technique. The method solves the technical problems that the non-stick performance of a non-stick pan in the prior art is poorer and pollution can be easily caused. The method comprises the following steps that a, surface pattern treatment: concave-convex lines with preset patterns are formed in a preset zone on the surface of a stainless steel plate through a chemical etching, graving or rolling depression method; b, drawing forming: the stainless steel plate body is drawn to form a pan body, and the preset zone is positioned in the working zone of a formed pan body; c, spraying of non-stick coating: non-stick coating is sprayed to the preset zone on the inner surface of the pan body, so that the non-stick coating is coated on the preset zone on the inner surface of the pan body; d, polishing: the preset zone on the inner surface of the pan body is subjected to mechanical polishing, the non-stick coating on the convex surfaces of the concave convex lines is removed, and the non-stick coating on the concave surfaces of the concave convex lines is retained. The method for manufacturing the stainless steel or compound steel non-stick pan has the advantages of durability and good non-stick property.

Description

technical field [0001] The invention belongs to the technical field of non-stick pan manufacturing technology, and relates to a manufacturing method of a non-stick pan, in particular to a manufacturing method of a stainless steel or composite steel non-stick pan. Background technique [0002] Currently on the market, stainless steel cookware has the advantages of being non-rusting and light, and is very popular among users. However, the only disadvantage is that stainless steel cookware is particularly sticky, which is the most unacceptable point when using it. In order to solve this shortcoming, everyone uses metal-plated ceramic oxide film or sprays non-stick paint, etc., which is always unsatisfactory. Metal-plated ceramic oxide film is used, although the non-stick performance of light stainless steel cookware has improved, but there is a big gap compared with non-stick coatings. Spraying non-stick coatings directly on stainless steel, the non-stick performance is very go...
