Above-mentioned drying oil alkyd resin is mixed with Oleum Cinnamomi, at 90-100 ℃ of lower insulated and stirred 6-8 minute, the reduction temperature is 55-65 ℃, adds the hexamethoxymethyl melamine resin, after fully stirring, adds Union carbide A-162,200-300 rev/min of dispersed with stirring 10-15 minute, the rising temperature is 130-135 ℃, adds each raw material of residue, insulation reaction 1-3 hour, be cooled to normal temperature, obtain described film coalescence aid.

A kind of preparation method of volatile rust preventive oil comprises the following steps:

Above-mentioned No. 50 machinery oil are mixed with the 25# transformer oil, at 100-110 ℃ of lower stirring reaction 15-20 minute, add sylvic acid polyoxyethylene ester, alkenyl succinic acid, alkylphenol polyoxyethylene, epoxyeicosatrienoic acid magnesium, add each raw material of residue after fully stirring, at 85-90 ℃ of lower insulated and stirred 2-3 hour, filter discharging, obtain described volatile rust preventive oil.

Advantage of the present invention is:

Slushing oil of the present invention had both had the rust-preventing characteristic of slushing oil contact, had again the high-performance of vapour-phase inhibitor volatile rust prevention, can be widely used in the various metals material.
