Problems solved by technology

The stainless steel knives on the existing market are basically stainless steel surfaces, and there are the following problems: 1) stainless steel contains heavy metal elements such as Cr and Cu, which are prone to overflow of heavy metals during daily use, are easy to stick to sticky food, and are not easy to clean. Residual traces; 2) Ordinary stainless steel does not have antibacterial function, and harmful bacteria are easy to breed on stainless steel products. It is used on stainless steel products that human beings come into contact with every day, especially like it is easy to cause the contact transmission of bacteria, which brings hidden dangers to human health; 3) Ordinary stainless steel has poor wear resistance

Abstract

The invention discloses an anti-adhesion stainless steel cutter and a preparation method thereof. The anti-adhesion stainless steel cutter comprises a hilt and a cutter face, wherein the cutter face comprises a stainless steel substrate; a silver thin film is deposited on the outer surface of the stainless steel substrate by a vacuum coating method, and an anti-adhesion layer coats the outer surface of the silver thin film. The preparation method comprises the following steps: (1) pretreatment, (2) film coating, (3) roller coating, and (4) assembling. The anti-adhesion stainless steel cutter has the features of high anti-bacterial property, high wear resistance, high corrosion resistance and high strength. In addition, the anti-adhesion stainless steel cutter has the features that the cutter cannot be adhered to sticky food easily and is convenient to clean.

Description

technical field [0001] The invention relates to a cutting tool, in particular to an anti-adhesion stainless steel cutting tool and a preparation method thereof. Background technique [0002] Stainless steel has excellent performance and is widely used in various fields of daily life, such as tableware, towel racks, sinks, elevators, railings, door handles, restaurant carts, food counters, containers, surgical carts in hospitals, etc. In daily life, knives are essential. In order to meet the requirements of anti-corrosion, a large number of knives are made of stainless steel. The stainless steel knives on the existing market are basically stainless steel surfaces, and there are the following problems: 1) stainless steel contains heavy metal elements such as Cr and Cu, which are prone to overflow of heavy metals during daily use, are easy to stick to sticky food, and are not easy to clean. Residual traces; 2) Ordinary stainless steel does not have antibacterial function, and...
