Technical Field

[0001] The invention belongs to the technical field of cleaning fluids, and in particular relates to a high-efficiency rust-proof cleaning fluid for a spindle picking device of a cotton picker. Background Art

[0002] At present, cotton picking has achieved mechanized picking operations of cotton pickers on a large scale, which has liberated a large amount of manpower, greatly improved picking efficiency, shortened picking period, and reduced picking costs. The picking spindle device of the cotton picker is an important working unit of the cotton picker, and the cleaning fluid of the cotton picker is a consumable. Its main function is to ensure that the picking spindle head is clean and free of debris. Due to the wide geographical range, the water quality varies greatly, and the water mineralization ranges from 70PPM to 7000PPM+. The commercially available cleaning fluid cannot effectively solve the corrosion and rust problems of the emulsion configured with high-mineralized water as emulsified water, causing corrosion and rust in the pumping and spraying systems, damaging the pump body and metal parts, and clogging the filter. As a result, the cotton picking operation cannot proceed smoothly and affects the normal production of the cotton picker, greatly reducing the working efficiency of the cotton picker, increasing maintenance and use costs, and the cotton picker owners are miserable.

[0005] The kinematic viscosity of the hydrogenated regenerated oil at 40°C is 12 to 28 mm 2 / s, freezing point below -26°C, flash point above 150°C.

[0006] The fluorocarbon surfactant is a mixture of the compound represented by formula I and the compound represented by formula II in a mass ratio of 2:1;

[0007] ;

[0008] Formula I;

[0009] ;

[0010] Formula II.

[0011] The composite rust inhibitor is a mixture of diethanolamine borate and barium dinonylnaphthalenesulfonate in a mass ratio of 1:3.

[0012] The composite rust preventive comprises the following components in parts by weight: 1-4 parts of benzotriazole, 10-20 parts of chitosan quaternary ammonium salt, 20-30 parts of β-hydroxyethyl methacrylate, 10-15 parts of sodium sulfate of fatty alcohol polyoxyethylene ether, and 30-50 parts of water.

[0013] The preparation method of the composite rust inhibitor is carried out according to the following steps: adding the above components in proportion to a high-speed stirring tank, heating to 70-90° C., stirring to form a translucent emulsion for standby use.

[0014] The preparation method of the cleaning liquid for the rust-proof cotton picker spindle picking device is carried out according to the following steps: adding hydrogenated regenerated oil into a blending kettle, stirring and heating to 50-60° C., adding fatty alcohol polyether, alkylphenol polyether, polyol polyether, fluorocarbon surfactant, and composite rust inhibitor in sequence, and continuing to stir for 20-40 minutes until uniform dispersion is obtained to obtain a light yellow transparent liquid, which is the cleaning liquid.
