Description

Technical Field

[0001] The utility model relates to the technical field related to metal surface anti-rust layer structures, in particular to a metal surface anti-rust layer structure. Background Art

[0002] Metal materials generally refer to pure metals or alloys used in industrial applications. There are about 70 kinds of pure metals in nature, among which the most common ones are iron, copper, aluminum, tin, nickel, gold, silver, lead, zinc, etc. The development of human civilization and social progress are closely related to metal materials. Steel materials, as the most widely used and most consumed metal material, are widely used in people's daily lives.

[0003] During use, metal steel is very easy to react with the surrounding medium and corrode and rust, among which chemical corrosion and electrochemical corrosion are the main forms of corrosion. After the steel rusts, a rust layer will appear on its surface, which increases the roughness of the steel surface, resulting in a decrease in surface hardness, reduced strength, poor ductility, and prone to cracks and breakage, thereby affecting the physical properties and service life of the steel. Utility Model Content

[0004] In order to solve the defects in the prior art, the utility model provides a metal surface anti-rust layer structure.

[0020] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0021] Example: Figure 1 and Figure 2 As shown, the utility model is a metal surface rust-proof layer structure, comprising an adhesive layer 2 adhered to the surface of a metal substrate 1, a plurality of circular holes 3 are opened on the adhesive layer 2, a zinc column 4 is embedded in each circular hole 3, a zinc sheet layer 5 is arranged on the side of the adhesive layer 2 away from the metal body, a plurality of zinc columns 4 are fixedly connected to the zinc sheet layer 5, a heat insulation layer 6 is arranged on the zinc sheet layer 5, a first waterproof layer 7 is arranged on the side of the heat insulation layer 6 away from the zinc sheet layer 5, and a wear-resistant layer is arranged on the side of the first waterproof layer 7 away from the heat insulation layer 6 8. The zinc sheet layer 5 is connected to the metal substrate 1 through the zinc column 4. Based on the concept of the primary cell, the zinc sheet layer 5 and the zinc column 4 are used as sacrificial anodes (i.e., as negative electrodes in the primary cell), and are connected to the metal substrate 1 (i.e., cathode or positive electrode) that needs to be protected. Since the sacrificial anode has a stronger reducing property, it will undergo an oxidation reaction in the battery and be gradually consumed, thereby protecting the metal substrate 1 that is connected together from corrosion, preventing the metal substrate 1 from rusting due to electrochemical corrosion, and achieving rust prevention of the metal substrate 1.

[0022] Among them, a second waterproof layer 9 is arranged between the zinc sheet layer 5 and the thermal insulation layer 6. By arranging the first waterproof layer 7, the second waterproof layer 9, the adhesion layer 2 and the thermal insulation layer 6, it is possible to prevent external moisture and air from contacting the metal substrate 1, thereby ensuring the dryness of the metal substrate 1 and preventing the metal substrate 1 from corrosion and rust.

[0023] Among them, a water-absorbing layer 10 is arranged between the second waterproof layer 9 and the heat-insulating layer 6. The water-absorbing layer 10 is filled with silica gel desiccant. By utilizing the excellent water absorption of the silica gel desiccant, part of the water infiltrated from the first waterproof layer 7 can be adsorbed and removed.

[0024] The second waterproof layer 9 is coated on the outer surface of the water absorbing layer 10 , which can prevent the silica gel desiccant in the water absorbing layer 10 from moving and leaking.

[0025] Among them, a reinforcement layer 11 is arranged between the water-absorbing layer 10 and the heat-insulating layer 6. The reinforcement layer 11 is a mesh structure made of tough fibers. The reinforcement layer 11 can improve the toughness and strength of the anti-rust layer structure, making the anti-rust layer structure less susceptible to scratches and damage.

[0026] The wear-resistant layer 8 is made of wear-resistant ceramic material. The characteristics of the wear-resistant ceramic can improve the wear resistance of the anti-rust layer structure and the metal substrate 1 and reduce the wear of the anti-rust layer structure and the metal substrate 1.

[0027] During operation, the anti-rust layer structure is adhered to the surface of the metal substrate 1 through the adhesive layer 2, and the zinc sheet layer 5 is connected to the metal substrate 1 through the zinc column 4. Based on the concept of the primary battery, the zinc sheet layer 5 and the zinc column 4 are used as sacrificial anodes (i.e., as negative electrodes in the primary battery) and are connected to the metal substrate 1 (i.e., cathode or positive electrode) to be protected. Since the sacrificial anode has a stronger reducing property, it will undergo an oxidation reaction in the battery and be gradually consumed, thereby protecting the metal substrate 1 connected together from corrosion, and preventing the metal substrate 1 from being damaged due to electrochemical corrosion. The first waterproof layer 7, the second waterproof layer 9, the adhesion layer 2, the insulation layer 6 and the water absorption layer 10 can prevent the external moisture and air from contacting the metal substrate 1, ensure the dryness of the metal substrate 1, and further avoid the corrosion and rust of the metal substrate 1. The wear-resistant layer 8 can improve the wear resistance of the anti-rust layer structure and the metal substrate 1, and reduce the wear of the anti-rust layer structure and the metal substrate 1. The reinforcement layer 11 can improve the toughness and strength of the anti-rust layer structure, so that the anti-rust layer structure is not easily scratched and damaged.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
