3New cobalt decanoate is the higher adhesion promotor of a kind of activity, is mainly used in steel wire cord, the rope of natural rubber, synthetic rubber or these glue and brass, zinc, naked copper and brass-plating or zinc, the adhesion promotion of metal sheet.It is to be raw material with cobaltous hydroxide and neodecanoic acid, carries out that acid-base reaction forms.Contain the cobalt amount by the new cobalt decanoate of this method preparation and have only 14.7%, do not reach the rubber production service requirements.And it is the soft organic cobalt salt of a kind of heavy-gravity at normal temperatures, just becomes liquid about 50 ℃.Fusing point is lower, can't become solid under the normal temperature, is inconvenient to transport and be unfavorable for rubber production.
Summary of the invention:
The objective of the invention is to overcome above-mentioned deficiency, a kind of preparation method based on the organic cobalt class mixing salt finished product of new cobalt decanoate who contains that the cobalt amount is higher, fusing point is higher is provided.
The object of the present invention is achieved like this: a kind of preparation method of the organic cobalt class mixing salt finished product based on new cobalt decanoate, it is characterized in that it is is raw material with cobaltous hydroxide and organic acid, carry out acid-base reaction and sour replacement(metathesis)reaction forms, this method comprises following processing step:
Step 1, salt-forming reaction
Mixing acid with cobaltous hydroxide and propionic acid and neodecanoic acid is raw material, in the normal pressure sealed vessel, and 150 ℃～190 ℃ of temperature, time 〉=2 hour, reaction generates Cobaltous propionate and new cobalt decanoate mixing salt, and its total reaction formula is:
Wherein: n=2 or 9, m=2 or 9.
Step 2, sour replacement(metathesis)reaction
In above-mentioned reaction system, must be that propionic acid reaches 20%, neodecanoic acid reaches 60%, the mixing salt that makes cobalt contents could surpass 20%, fusing point reaches 80-110 ℃.But propionic acid percentage composition in mixing cobalt class salt increases also defectiveness, after this mixing salt is dispersed in and vulcanizes disassociation in the rubber, because the acidity of free propionic acid is strong (the propionic acid acid number is 758mgKOH/g), may quicken the corrosion of the aging and material steel wire of glue based article, consider above-mentioned factor, in above-mentioned reaction system, add PIVALIC ACID CRUDE (25) (the PIVALIC ACID CRUDE (25) acid number is 550mgKOH/g), 190 ℃～200 ℃ of controlled temperature, time 〉=1 hour, reaction displaces propionic acid, the acidity of free PIVALIC ACID CRUDE (25) is obviously than a little less than the propionic acid, can reduce the corrosion of the aging and material steel wire of glue based article, and not influence cobalt contents and the fusing point that mixes cobalt salt, if increase the PIVALIC ACID CRUDE (25) ratio, then the product fusing point is on the low side, otherwise then cobalt contents is higher.Its reaction formula is:
Wherein: n=2, m=2 or n=2, m=9.
Step 3, make finished product
In above-mentioned reaction system, temperature is controlled at 180-190 ℃, adds calcium metaborate, makes the organic cobalt class mixing salt finished product based on new cobalt decanoate.
Prepare each material performance of the present invention and require as follows:
