Description

Technical Field

[0001] The invention relates to the technical field of anti-oxidation, in particular to an anti-oxidation and anti-blackening agent for welding around a stainless steel joint seam and a construction process. Background Art

[0002] Stainless steel, full name stainless acid-resistant steel, refers to a series of steels with high chemical stability in air, water, salt aqueous solution, acid and other corrosive media; it is an alloy steel containing more than 13% chromium, and some also contain other elements such as nickel and titanium. Invented by British metal expert Brearley in 1914, stainless steel is divided into different materials such as 304 and 316, and the types include ferritic stainless steel, martensitic stainless steel and austenitic stainless steel. It has the characteristics of corrosion resistance and heat resistance. Its corrosion resistance decreases with the increase of carbon content. Most stainless steels have a low carbon content, with a maximum of no more than 1.2%. It is a widely used elevator decoration material, which can be used for floor doors, door frames, door lintels, car doors and car walls. When welding workpieces made of stainless steel, the welds around the joints need to be treated with anti-oxidation to avoid blackening.

[0003] After searching, it was found that there are several methods for preventing oxidation and blackening around the welding of stainless steel joints in the prior art:

[0004] The first is to apply paint. Paint can isolate the stainless steel surface from the air. Although this can prevent it from oxidation in a short time, it is not long-lasting. After a period of time, the paint welded around the stainless steel joint will fall off.

[0005] The second is to set a coating, such as a floodlight pole and its preparation method with publication number CN108826240B. The anti-oxidation stainless steel floodlight pole of the invention adopts a reasonably matched stainless steel component and a specific preparation method, so that the prepared floodlight pole has high strength and good anti-oxidation performance;

[0006] The floodlight pole and preparation method thereof are characterized in that a ZrBMoS coating is coated on the surface of a main body to improve its hardness, wear resistance and oxidation resistance. The raw material of the ZrBMoS coating is a mixture of two powders of ZrB2 and MoS2 at a Zr:Mo atomic ratio of 1:1. However, since ZrB2 and MoS2 are in powdery structures, the mixed raw materials do not have adhesion and can only be manually sprayed onto the main body. In this way, the uniformity of the spraying cannot be guaranteed, resulting in uneven powder thickness on the surface of the main body, thereby reducing the oxidation resistance effect.

[0007] In view of this, the present application designs an anti-oxidation and anti-blackening agent and a construction process for welding around stainless steel joints to solve such problems. Summary of the invention

[0008] In view of the deficiencies in the prior art, the present invention provides an anti-oxidation and anti-blackening agent for welding around stainless steel joint seams and a construction process, which solves the problem that the prior art has poor anti-oxidation and anti-blackening effects for welding around stainless steel joint seams.

[0009] To achieve the above objectives, the present invention is implemented through the following technical scheme: an anti-oxidation and anti-blackening agent for welding around stainless steel joints, the anti-oxidation and anti-blackening agent comprising the following ingredients: 180-200 kg of ethanol, 14-34 kg of boric acid, 2-4 kg of borax and 2-4 kg of boron carbide.

[0010] Preferably, the anti-oxidation and anti-blackening agent formula is composed of the following grams: the anti-oxidation and anti-blackening agent formula is composed of the following grams: 180 kg of ethanol, 14 kg of boric acid, 2 kg of borax, and 2 kg of boron nitride.

[0011] Preferably, the anti-oxidation and anti-blackening agent formula is composed of the following grams: 190 kg of ethanol, 24 kg of boric acid, 3 kg of borax, and 3 kg of boron nitride.

[0012] Preferably, the anti-oxidation and anti-blackening agent formula is composed of the following grams: 200 kg of ethanol, 34 kg of boric acid, 4 kg of borax, and 4 kg of boron nitride.

[0013] An anti-oxidation and anti-blackening agent for welding around stainless steel joints, comprising the following construction processes:

[0014] S1: Pour the ethanol weighed in proportion into a container, and pour the boric acid, borax and boron nitride weighed in proportion into the ethanol;

[0015] S2: stirring the materials in the container by a stirring rod until the boric acid, borax, boron nitride and ethanol are dissolved to prepare an anti-oxidation and anti-blackening agent;

[0016] S3: Apply the anti-oxidation and anti-blackening agent evenly to the welding area around the stainless steel joint seam;

[0017] S4: Let it stand for a while until the anti-oxidation anti-black agent forms a protective film around the weld of the stainless steel joint.

[0018] Beneficial Effects

[0019] The present invention provides an anti-oxidation and anti-blackening agent for welding around stainless steel joint seams and a construction process, which has the following beneficial effects:

[0020] The ethanol weighed in proportion can be poured into a container, and the boric acid, borax and boron nitride weighed in proportion can be poured into the ethanol, and the materials in the container can be stirred by a stirring rod until the boric acid, borax and boron nitride are dissolved with the ethanol to prepare an anti-oxidation anti-blackening agent, and then the anti-oxidation anti-blackening agent can be evenly applied to the welding part around the stainless steel joint seam, and left to stand for a period of time until the anti-oxidation anti-blackening agent forms a protective film at the welding part around the stainless steel joint seam;

[0021] Since the aqueous solution of boric acid is weakly acidic, adding boric acid can improve the mechanical strength. Borax is the most important compound of the boron element. After adding borax, it can be used to purify the metal surface and remove oxides on the metal surface. Boron carbide has the characteristics of low density, high strength, high temperature stability and good chemical stability. Adding boron carbide can make boric acid and borax better mixed with ethanol. The solution obtained has a certain adhesion and can be applied to the welding around the stainless steel joint seam, thereby having a better anti-oxidation and anti-blackening effect on the welding around the stainless steel joint seam.
