Description
Technical field
The present invention relates to compound stabilizer field, and in particular to a kind of cyanuric acid lanthanum is modified calcium-zinc composite stabilizing agent and its system
Preparation Method.
Background technology
Stabilizer for plastics is necessary additive in plastic processing, the photostability, thermally-stabilised for improving plastic products
Property, improve its heat resistanceheat resistant solution and the property indices such as anti-aging, and improve plasticizing and the extrusion performance of plastic processes.
Stabilizer includes base lead salt, fatty acid soaps, organotin, organic auxiliary stabilizer etc.；Such as：1. tribasic carbonic acid
Lead, the heat resistance of dibasic lead phosphite, electrical insulating property are preferable, but poisonous, transparent and bad dispersibility, and CABLE MATERIALS is stable with such
Based on agent；2. fatty acid soaps generally two or more and to produce cooperative effect, wherein cadmium soap and barium soap is poisonous, calcium zinc stabilizer
With it is environment-protecting and non-poisonous the characteristics of, be the unique selection of generally acknowledged at present replacement lead salt, it is adaptable to various PVC, rubber, part coatings
Product or product；3. organotin has the good transparency, and the heat resistance and weatherability of many kinds are very prominent, but price
Height, application is small, is used for clear plastic articles at present；4. organic auxiliary stabilizer is typically then the auxiliary of aforementioned stable agent
Property additive, to improve certain performance indications.
Generally all there are various shortcomings in existing stabilizer, although wherein calcium zinc stabilizer have it is environment-protecting and non-poisonous,
The HCl that the degraded of the characteristics of wide adaptability, theoretically zinc-iron alloy solution PVC is produced, blocks degraded, but the zinc chloride of generation is catalyzed on the contrary
Degraded, therefore its stability is poor, the phenomenon for burning zinc easily occurs, while the coloring at its initial stage is also and good.
The content of the invention
It is an object of the invention to provide the preparation method that a kind of cyanuric acid lanthanum is modified calcium-zinc composite stabilizing agent, solve existing
The problem of calcium zinc stabilizer stability difference and poor initial coloring.
To solve above-mentioned technical problem, the present invention uses following technical scheme：
A kind of cyanuric acid lanthanum is modified the preparation method of calcium-zinc composite stabilizing agent, comprises the following steps：A. added into reactor hard
Resin acid, heating melts it, is kept molten by after stearic acid melts completely；B. into the stearic acid of molten condition at the uniform velocity
Zinc oxide is added, catalyst α is added dropwise while zinc oxide is added, after the completion of zinc oxide is added, waits it to react 7~15 minutes
Afterwards, addition calcium hydroxide at the uniform velocity, catalyst β is added dropwise while calcium hydroxide is added；C. after the completion for the treatment of that calcium hydroxide is added,
Keep reacting and progressively rising to temperature 100~115 DEG C, during which moisture progressively evaporates, obtained after moisture progressively evaporates completely
Fused materials containing calcium zinc stearate；D. the fused materials containing calcium zinc stearate are cooled down into tabletting, then by its powder
Powdery is broken to, obtained granular material is added into mixer with ready cyanuric acid lanthanum in proportion, auxiliary stabilizer and auxiliary material
In be well mixed obtain mixture x；E. mixture x progress extruding pelletizations are obtained into graininess finished product.
Addition zinc oxide in step b into the stearic acid of molten condition at the uniform velocity, at the same be added dropwise catalyst α, be in order that
Stearic acid and zinc oxide are reacted rapidly in the presence of catalyst α, generation zinc stearate, addition calcium hydroxide at the uniform velocity,
Catalyst β is added dropwise simultaneously, is that generation is hard in order that stearic acid and calcium hydroxide are reacted rapidly in the presence of catalyst β
Resin acid calcium, without using calcium oxide is that alkalescence is strong because calcium oxide is quick lime using calcium hydroxide, heating is serious, uses hydrogen
Calcium oxide can be such that reaction more relaxes, will not be excessively fierce, and waiting zinc oxide to add calcium hydroxide after reacting 7~15 minutes is
Allow the latter to be reacted again because waiting the former to react, progressively rising to temperature during 100~115 DEG C, moisture meeting
Gradually evaporate, temperature is stepped up being to control reaction speed, it is to avoid reaction is excessively violent, generates various accessory substances, simultaneously
The phenomenon of excessive pot is prevented, it is to improve prepare compound steady to be eventually adding cyanuric acid lanthanum, auxiliary stabilizer and auxiliary material
Determine the stability of agent finished product and the coloring at initial stage, the mechanism of action of cyanuric acid lanthanum is to be complexed chlorine atom active in VC chains, and
Calcium stearate is to absorb PVC thermal decomposition abjection HCl gases, so inhibited in terms of two cause PVC unstable two kinds because
Element, and during zinc stearate exclusive use, initial coloration is good, but serious " zinc burning " phenomenon, the control of cyanuric acid lanthanum then occurs
Initial coloration effect is general, but long-time stability are preferably, therefore cyanuric acid lanthanum is cooperateed with zinc stearate, can control initial stage
Color is simultaneously able to maintain that the hot steady time is longer compared with zinc stearate, postpones the generation of " zinc burning " phenomenon or overcomes " zinc burning " existing
As.
As present invention further optimization, during stearic acid thawing is made in the step a, when stearic acid melts
After more than 20%, stearic acid is stirred until thawing completely.
It is stirred when after stearate moiety thawing, can accelerates to melt, improve production efficiency.
As present invention further optimization, during catalyst α and catalyst β in the step b are acetic acid, step b
The stearic acid of molten condition, zinc oxide, catalyst α, calcium hydroxide and catalyst β mass fraction are respectively the hard of molten condition

Can so it make reaction more abundant, it is to avoid to cause the waste of raw material.
As present invention further optimization, the auxiliary stabilizer in the step d is mercaptans type, and auxiliary material is Tissuemat E
And epoxidized soybean oil, the content of stearate is accounted in the 8%~10% of granular material gross mass, step d in the granular material
Granular material, cyanuric acid lanthanum, mercaptans type, Tissuemat E and epoxidized soybean oil according to the mass fraction be respectively granular material 90~
6~10 parts of 100 parts, 2~4 parts of cyanuric acid lanthanum, 1~2 part of mercaptans type, 27~30 parts of Tissuemat E and epoxidized soybean oil.
The stability of compound stabilizer finished product and the coloring at initial stage can be improved after adding cyanuric acid lanthanum, and antimonic salt and calcium
Synergy is also fine, therefore can further improve the stability of compound stabilizer finished product after addition mercaptans type, so have selected
Mercaptans type adds Tissuemat E and epoxidized soybean oil is that the modeling of material is obtained after mixing in order to improve as auxiliary stabilizer
The performance such as the property changed and lubricity, processing of being more convenient for.
As present invention further optimization, the preparation method of the cyanuric acid lanthanum in the step d comprises the following steps：
（1）Water and cyanuric acid are proportionally added into reactor, 60~80 DEG C is heated under then stirring, treats that cyanuric acid is completely dissolved
Yu Shuizhong, forms cyanuric acid solution for later use；（2）Before step a is carried out or while carrying out step a, it is ready in proportion
Water, lanthana, ready lanthana are added in ready water suspension are made；（3）Suspension is at the uniform velocity added to
In cyanuric acid solution, both is persistently reacted, temperature is progressively risen to 80~85 DEG C when being reacted；（4）Step is treated
（3）In reaction after the completion of cool the temperature to 10~30 DEG C, will react obtained reaction solution filtered, washed, drying and powder
It is broken, finally give cyanuric acid lanthanum.
