Class powder barium zinc compound stabilizer is mainly mixed with powdery monomer calcium stearate, barium stearate with certain proportion, in production process
Sewage discharge and dust pollution are its common abuses, and monomer stearate production technology is common double decomposition, one step of water phase, high pressure
Method etc., thus have aqueous condition cannot a step production stearates barium zinc compound stabilizer.General non-pressure process dry method is because of reaction
Product fusing point is poor compared with high fluidity and high-temperature material denaturation, color and luster are yellow, can not effectively produce.
The One-step production powder barium zinc of the present invention stablizes agent method, and by reaction process, a step is completed in a device,
Discharge after reaction, smash to obtain finished product, in the presence of effectively overcoming the shortcomings of the prior art.
The content of the invention
The technical problems to be solved by the invention are in view of the deficiencies of the prior art, there is provided a kind of One-step production barium zinc is steady
Determine the method for agent, efficiently solve sewage discharge and dust dirt in powder stearates barium zinc compound stabilizer production process
The problem of dye, while improve the heat endurance and lubricity of heat stabilizer.
In order to solve the above technical problems, the present invention provides a kind of method of One-step production barium zinc stabilizer, step is such as
Under：
Stearic acid, zinc oxide, barium hydroxide are proportionally added into and mediate reaction kettle heating reaction；
When temperature is heated to 30-60 DEG C, catalyst is added, continues heating stirring；
When temperature is 90-160 DEG C, insulation reaction is to producing vapor；
Reaction be evaporated completely to vapor it is full-time, sampling survey free acid, measure free acid less than 1% when, reaction terminates；
Material is cooled to less than 100 DEG C, when material is in irregular solid, carrying out attrition grinding by kneading reaction kettle goes out
Material, obtains powder barium zinc stabilizer.
Further, the stearic acid, zinc oxide, the molar ratio of barium hydroxide are 4:0-1:2-1.
Further, the catalyst is hydrogen peroxide, and the dosage of the hydrogen peroxide is the 0-10% of stearic acid quality.
Further, the kneading reaction kettle has crushing system, heating system and a cooling system, the crushing system,
Heating system and cooling system, which are arranged at, to be mediated in reaction kettle.
Preferably, the crushing system adjusts the fineness of the powder barium zinc stabilizer.
The beneficial effects of the invention are as follows：The method of One-step production barium zinc stabilizer of the present invention, step is simple, operation side
Just, using reaction kettle is mediated as reaction unit, make to discharge without waste water, exhaust gas, dust etc. in production process, energy conservation and environmental protection, subtracts
Lack environmental pollution, and temperature is low in reaction process, and material will not turn yellow, and stability of characteristics, can also be by adjusting raw material
Mol ratio controls the content of zinc in stabilizer, effectively overcomes the zinc in the resins such as polyvinyl chloride and plastic processes to burn existing
As, while heat endurance and lubricity are improved, anti-aging, lubrication in plastic containing chlorine such as polyvinyl chloride production, processing can be used as
Class stabilizer.
