Description
Technical field
The present invention relates to technical field of fine, and in particular to a kind of production technology of barium stearate.
Background technique
Barium stearate belongs to one of stearates, has good long-term heat resistance and lubricity, can be used as gathering
Vinyl chloride is fast light heat-resisting stabilizing agent and lubricant.In the stearate of all alkaline-earth metal, the long-term heat resistance of barium stearate
Preferably, it is mainly used for flexible transparent film, thin plate, artificial leather and hard plate, pipe etc., also acts as high temperature resistant release agent and machine
Tool high-temperature lubricant, application is very extensive, and market demand increases year by year.
There are mainly two types of production technologies for domestic production barium stearate at present, and one is stearic acid and barium hydroxide in catalyst
Under the action of directly react, be commonly called as dry method barium stearate；Also one is stearic acid and barium hydroxide in water phase, in catalyst
Under the action of directly react, obtain barium stearate, be commonly called as water law magnesium stearate.There are bulk densities for the barium stearate that dry method obtains
Greatly, the disadvantage that the reaction time is long and reaction heating temperature is high, there are free acid height and low-melting quality for obtained barium stearate
Disadvantage, and water law barium stearate is there is also reaction time long energy consumption is high, product quality can only meet the standard of Grade A.
Summary of the invention
In view of the defects and deficiencies of the prior art, the present invention intends to provide a kind of production technologies of barium stearate.
To achieve the above object, the technical solution adopted by the present invention is that: a kind of production technology of barium stearate, innovative point
It is, includes the following steps:
(1) 300 parts of water is added in a kettle, is added 9 parts of liquid alkaline, heating is added to 85 DEG C, 20 parts of investment it is hard
Reaction is sufficiently stirred in resin acid；
(2) will to be made into barium chloride solution with 10 parts of barium chloride and 30 parts of water stand-by；
(3) when spuming when occur liquid level rising in reaction kettle, pH value is quickly put between 9-11 in test reaction kettle
Barium chloride solution is simultaneously heated by steam, and the aperture of the speed and steam valve of control plus aqueous solution, control reaction temperature are passed through
Degree reacts the solution in reaction kettle sufficiently at 90 DEG C；The speed for adding aqueous solution is 30L/min；About 3 DEG C of rate of rise in temperature/
Min, steam valve aperture are 1.5 turns；
(4) it after feeding intake, is decreased obviously to liquid level, steam off, to occur apparent water material point in reaction kettle
Layer, reaction terminates, by filtering and drying obtained barium stearate.
Further, the water in the step 1 includes the salt water for having sodium chloride after previous kettle material dewatering and addition
New water, the weight ratio of the two is by 2:1.
Further, the barium chloride solution temperature in the step 2 is 58-62 DEG C.
The invention has the following beneficial effects:
1, present invention process is simple, and the water in the present invention includes the new water of the water and addition after previous kettle material dewatering, no
Disconnected to be applied, there are two types of advantages: first is to save water resource, and second is the salt water for having sodium chloride by the way that part is added, suppression
The progress of system displacement reaction, to guarantee range of the content in high-class product of barium stearate；And the ratio of this two-part water is
Proportion addition is carried out in the ratio of 2:1, dewatered coolant-temperature gage is high, while can also save the energy consumption of initial reaction heating.
2, the present invention in 90 DEG C be displacement reaction optimum temperature, it can be ensured that the choicest quality of barium stearate product,
The barium chloride solution of preference temperature is heated and is added in invention by steam, to adjust reaction temperature.
3, the present invention is lower than dry method barium stearate technique and water law barium stearate technique in the consumption of steam and electricity.
Specific embodiment
The present invention is further illustrated for following example.
In order to make the objectives, technical solutions, and advantages of the present invention clearer, below in conjunction with specific embodiment, to this
Invention is further elaborated.It should be appreciated that the specific embodiments described herein are only to explain the present invention, not
For limiting the present invention.
