Problems solved by technology

In addition, there is also controversy over whether PTFE non-stick pans have hidden dangers to human health during use, and disputes continue to arise
[0004] The utility model patent No. ZL95226356.4 discloses a new type of non-stick pan coated with an amorphous nickel-phosphorus alloy layer. Sticky pan, the coating has the characteristics of good wear resistance, low friction coefficient and good self-lubricating performance, which not only overcomes the short service life of traditional fluorine-containing non-stick pans, but also does not contain fluoride
However, nickel itself is a heavy metal, and nickel and phosphorus are harmful to the human body, and this patented technology has not been tested for the migration of heavy metals by EU food-grade hygiene indicators

Abstract

The invention concretely relates to a non-stick pan free of fluoride and a manufacturing method of the non-stick pan free of the fluoride. According to the technical scheme, the manufacturing method includes the steps that the inner surface of an aluminum alloy pan substrate (3) is firstly coated with a transition layer (2), and the transition layer (2) is made of aluminum oxide or aluminum nitride; the aluminum alloy pan substrate (3) coated with the transition layer (2) is subjected to ultrasonic cleaning in an acetone solution and dehydration treatment through absolute ethyl alcohol and dried; finally, by the adoption of a multi-arc ion plating technology, a hard ceramic layer (1) of a TiC or TICN or TIN nanostructure is deposited on the dried transition layer (2) on the aluminum alloy pan substrate (3) to obtain the non-stick pan free of the fluoride. The thickness of the transition layer (2) is 10-50 micrometers, and cleaning time of ultrasonic cleaning is 10-60 min. The non-stick pan free of the fluoride is simple in technique, the manufacturing process is safe and environmentally friendly, and the obtained non-stick pan has the advantages of being free of the fluoride, free of damage to health of human bodies, good in abrasive resistance and long in service life.

Description

technical field [0001] The invention belongs to the technical field of non-stick pans. Specifically relates to a fluoride-free non-stick pan and a preparation method thereof. Background technique [0002] In daily life, the phenomenon of food sticking to the pan often occurs when cooking food with traditional aluminum alloy pans. Scorched food not only destroys the appearance, but also easily produces harmful substances that endanger human health. In addition, it also increases the difficulty of cleaning the cooker. The existing method for solving the non-stick pan is to coat one deck of polytetrafluoroethylene (PTFE) on the surface of the aluminum alloy pan. [0003] Although existing non-stick pans can meet people's needs of not sticking pans when cooking food, the polytetrafluoroethylene coating has low strength and is easy to peel off and damage. When the surface hydrophobic substance is worn away, the non-stick pan loses its "non-stick" performance. Moreover, ther...
