Description
Technical field
The invention belongs to heat stabilizer production technical field, more particularly to a kind of One-step production powder calcium zinc stabilizer
Method.
Background technology
Currently, anti-aging, lubrication class stabilizer must be added in the production such as plastic containing chlorine such as polyvinyl chloride, processing.It is such as leaded
Type thermal stabilizing agent, organic tin heat stabilizer, liquid calcium zinc heat stabilizer, stearate type thermal stabilizing agent.General stearate
Class powder calcium-zinc composite stabilizing agent is mainly mixed with powdery monomer calcium stearate, zinc stearate with certain proportion, in production process
Sewage discharge and dust pollution are its common abuses.
Monomer stearate production technology is common double decomposition, one step of water phase, high-pressure process etc..Zinc stearate is in two in water
Property, it can be reacted with excessive alkali, produce meta-sodium zincate, material is tacky, cannot normally produce.Therefore, there is the aqueous condition cannot
One step produces stearates calcium-zinc composite stabilizing agent.General non-pressure process dry method because reaction product fusing point is poor compared with high fluidity and
High-temperature material is denaturalized color and luster Huang, can not effectively produce.
The One-step production powder calcium zinc stabilizer technological process of the present invention, can effectively overcome disadvantages mentioned above, detailed content
It has not been reported.
Invention content
The technical problem to be solved in the present invention is to provide sewage discharge and dust pollutions in a kind of avoidable production process, and
The method for improving heat stabilizer thermal stability and the One-step production powder calcium zinc stabilizer of lubricity.
In order to solve the above technical problems, the technical scheme is that：A kind of One-step production powder calcium zinc stabilizer
Method, innovative point are：The kneading with chuck heating is added with certain mol proportion in stearic acid, zinc oxide and calcium hydroxide
It stirs, heats up in machine, hydrogen peroxide is added at 50~60 DEG C and makees catalyst, continues heating stirring, kept the temperature at 90~130 DEG C anti-
It answers, reaction generates vapor, until vapor volatilizees completely substantially, sampling surveys free acid and is less than 1%, and reaction terminates.
Further, the molar ratio of the stearic acid, zinc oxide and calcium hydroxide is 4:0~1:2~1.
Further, the molar ratio of the stearic acid, zinc oxide and calcium hydroxide is 4:0.5~1:1.5~1.
Further, the dosage of the hydrogen peroxide is the 0~10% of stearic acid quality.
The advantage of the invention is that：The method of One-step production powder calcium zinc stabilizer of the present invention, production process without waste water,
Exhaust gas, dust emission, energy conservation and environmental protection, friendly process；Meanwhile in preparation process, reaction temperature control is relatively low, avoids high temperature
It is yellow that material is denaturalized color and luster；In addition, by the mol ratio of material, control Zn content can effectively overcome the resins such as polyvinyl chloride and modeling
Expect that the zinc in process burns phenomenon, while improving the thermal stability and lubricity of stabilizer；Zn content height have zinc burn phenomenon but
Lubricity is preferable, and the low no zinc of Zn content is burnt but lubricity is bad, thus the present invention rubbing stearic acid, zinc oxide and calcium hydroxide
You are than control 4:0~1:2~1.
Specific implementation mode
The following examples can make professional and technical personnel that the present invention be more fully understood, but therefore not send out this
It is bright to be limited among the embodiment described range.
Embodiment 1
In the 1000L for having chuck heating or cooling effect mediates reaction kettle, stearic acid 268kg, zinc oxide is added（99.5%）
20kg, calcium hydroxide（95%）27.5% hydrogen peroxide 25kg is added at 50-60 DEG C and makees catalyst, continues to heat for 20kg heat temperature raisings
Stirring, in 100-120 DEG C of insulation reaction, reaction generates vapor, until vapor is faint, sampling surveys free acid and is less than 1%, reaction
Terminate.Material is cooled to 100 DEG C hereinafter, material is in irregular powdery solid, under further attrition grinding processing fineness meets
It swims user to require, packaging is sold.
Embodiment 2
In the 1000L for having chuck heating or cooling effect mediates reaction kettle, stearic acid 268kg, zinc oxide is added（99.5%）
13.5kg, calcium hydroxide（95%）27.5% hydrogen peroxide 25kg is added at 30-50 DEG C and makees catalyst, continues to add for 26kg heat temperature raisings
Thermal agitation, in 100-120 DEG C of insulation reaction, reaction generates vapor, until vapor is faint, sampling surveys free acid and is less than 1%, instead
It should terminate.Material is cooled to 100 DEG C hereinafter, material is in irregular powdery solid, further attrition grinding processing fineness meets
Downstream user requirement, packaging are sold.
Comparative example
Traditional calcium zinc stabilizer preparation method includes producing zinc stearate and calcium stearate powder respectively, then again with certain proportion
It is uniformly mixed, powder primes 60kg zinc stearates is such as alternately added in 1000L taper stirred tanks（HG/T3667-2012）With
Primes 140kg calcium stearates（HG/T2424-2012）, stir 30 minutes, blowing packaging.
Powder calcium zinc stabilizer prepared by Examples 1 to 2 and comparative example is tested for the property, test result is seen below
Table：
| Test event | Embodiment 1 | Embodiment 2 | Comparative example |
| Material discolouration | Do not turn yellow under high temperature | Do not turn yellow under high temperature | Turn yellow under high temperature |
| Product thermal stability, oven heat method（120min colors） | It is light yellow | It is light yellow | White |
Test method is：
Oven heat method：Execution standard GB/T9349-2002 will be cut into length of side 15mm by the PVC pieces obtained by calcium zinc stabilizer
Square, do Oven test at 180 DEG C.Heat stabilizer static heat stability is characterized by the variation of print color
Quality, result corresponds to long-term thermal stability.
