Embodiment 1

[0007] A phosphating treatment method for petroleum chains, the steps of which are as follows: (1) Put petroleum chains in 7wt% sulfonic acid solution and soak them at room temperature for 1 hour; (2) Microwave the soaking solution, The power of microwave treatment is 300w, and the time is 20min; (3) Take out the petroleum chain and drain it, and soak it in 12wt% aluminum dihydrogen phosphate solution at a temperature of 40°C for 30min; (4) Take out the petroleum chain Drain, then soak in 16wt% potassium dihydrogen phosphate solution at a temperature of 50°C for 30 minutes; (5) After drying the petroleum chain, spray a layer of styrene with a coating thickness of 0.1mm.

Embodiment 2

[0009] A phosphating treatment method for petroleum chains. The steps of the treatment method are as follows: (1) put the petroleum chains into a 5wt% sulfonic acid solution and soak them at room temperature for 1 hour; (2) microwave the soaking solution, The power of microwave treatment is 300w, and the time is 20min; (3) Take out the petroleum chain and drain it, and soak it with 13wt% aluminum dihydrogen phosphate solution at a temperature of 40°C, and the soaking time is 30min; (4) Take out the petroleum chain Drain, then soak in 17wt% potassium dihydrogen phosphate solution at a temperature of 50°C for 30 minutes; (5) After drying the oil chain, spray a layer of styrene with a coating thickness of 0.05mm.

Embodiment 3

[0011] A phosphating treatment method for petroleum chains. The steps of the treatment method are as follows: (1) Put the petroleum chains into a 6wt% sulfonic acid solution and soak them at room temperature for 1 hour; (2) Microwave the soaking solution, The power of microwave treatment is 300w, and the time is 20min; (3) Take out the petroleum chain and drain it, and soak it in 12wt% aluminum dihydrogen phosphate solution at a temperature of 40°C for 30min; (4) Take out the petroleum chain Drain, then soak in 16wt% potassium dihydrogen phosphate solution at a temperature of 50°C for 30 minutes; (5) After drying the petroleum chain, spray a layer of styrene with a coating thickness of 0.07mm.

[0012] The products prepared in Example 1, Example 2, and Example 3 were not rusted after being placed in 5wt% sodium chloride solution for 3 months. And there is no corrosion phenomenon in 5wt% sulfuric acid solution and 5wt% sodium hydroxide solution for 20 days.

Abstract

The invention relates to a method for parkerizing petroleum chains. The method for parkerizing the petroleum chains includes the following steps that the petroleum chains are placed in a sulfoacid solution of which the concentration is 5wt%-7wt% and soaked in the sulfoacid solution for 1h at the normal temperature; microwave processing is conducted on the soak solution for 20min, and the power of microwave processing is 300w; the petroleum chains are taken out, drained off, and then soaked in an aluminum dihydrogen phosphate solution of which the concentration is 12wt%-13wt% for 30min at 40 DEG C; the petroleum chains are taken out, drained off, and further soaked in a potassium dihydrogen phosphate solution of which the concentration is 16wt%-17wt% for 30min at 50 DEG C; after being dried, the petroleum chains are sprayed by a layer of styrene, and the thickness of the coating is 0.05mm-0.1mm. The petroleum chains processed with the processing method have the good antirust performance and corrosion resistance.

Description

technical field [0001] The invention relates to a treatment method for petroleum chains, in particular to a phosphating treatment method for petroleum chains. Background technique [0002] Petroleum chains need to have anti-rust and corrosion-resistant functions. If the oil chain has poor anti-rust function or poor corrosion resistance, it will affect the normal use of the oil chain. It is a relatively common method to carry out surface phosphating treatment on petroleum chains. Through phosphating treatment, the surface of the oil chain has a layer of phosphating film, which can prevent rusting. However, the currently commonly used phosphating method is relatively polluting and not environmentally friendly, and a large amount of use will cause great pollution to the environment. Therefore, relevant scholars need to continue to improve it. Contents of the invention [0003] The technical problem to be solved: the problem of rusting of the oil chain after being used for...
