Abstract
The present invention relates to a kind of method for making the globulous stearate of the stabilizer, lubricant of PVC and isolator of thermoset plastics of phenol aldehyde and amino etc.. Said invention adds the stearic acid melt into glycol solution and the globulous stearate is obtained through mixing tharaughly and cooling. The shortcomings of poor flowability and serious pollusion caused by enormous powdery stearate used in plastic industry are overcome. Said invention has also the advantages of simple process and low cost.
Description
The present invention relates to a kind of PVC stablizer, lubricant, and the manufacture method of the stearate of thermosetting resin separant such as phenolic aldehyde, amino.
At present, in plastic working industry, domestic a large amount of uses be powder stearic acid salt, it exists two big defectives: the one, and mobile poor, in the middle of the higher plastic processing machinery of level of automation, powder stearic acid salt can produce obstruction, feeding is inhomogeneous, causes unstable product quality; The 2nd, dust pollution is serious, and it is healthy to influence operator.External existing stearate mainly by water react or scorification reaction, is used the tablets press mist projection granulating.
Purpose of the present invention will overcome above-mentioned defective exactly, proposes the method for a kind of suitable China's national situation, simple, cheap manufacturing stearate.
Technical scheme of the present invention is:
With the stearic acid heat fused, add metal oxide to stearic acid solution earlier, be heated to the stearate fusing point while stirring, restir one hour gets the stearate melt.
Its characteristic feature of an invention: the stearate melt that obtains is joined in the ethylene glycol solution, stir under 130 ℃ of temperature, cooling while stirring gets globular stearate.
Advantage of the present invention and effect are that method is simple, with low cost, suitable China's national situation, and the stearate import substitutes have solved mobile poor, the with serious pollution drawback of powder stearic acid salt.
Embodiment 1:
Get 300 gram stearic acid, with its fusing, adding 45 its chemical equation of gram metal oxide: ZnO are:
Warming while stirring is to 130C, and restir one hour gets the stearate melt, about 330 grams.
Again the stearate melt that makes is joined 130 ℃ ethylene glycol solution [C
2H
4(OH)
2] in.Ethylene glycol plays the dispersion medium effect.Cooling promptly gets the globular stearate product while stirring.
The also available CaO of metal oxide, PbO, BaO etc., concrete weight is determined according to mol ratio.
Claims (1)
1, globular stearate producing method, with the stearic acid heat fused, add metal oxide, warming while stirring is to the stearate fusing point, restir one hour gets the stearate melt, it is characterized in that the stearate melt is joined in the ethylene glycol solution, cooling while stirring gets globular stearate under 130 ℃ of temperature.
