Description
Technical field
The present invention relates to a kind of preparation and application of cyanuric acid zinc/efficient PVC stabilizer of urea pyrimidine zinc Compositional type, the present invention
It is related to cyanuric acid zinc/new application in terms of PVC thermal stability for the efficient PVC stabilizer of urea pyrimidine zinc Compositional type.
Background technology
Commonly use PVC heat stabilizer at present with the heat stabilizer containing metal ion such as lead salts, metal soap, organic tin
Based on.With the enhancing of mankind's environmental consciousness, just starting research and development Environment-friendlyheat heat stabilizer both at home and abroad to replace traditional non-environmental protection
The upsurge of kind.Pure organic heat stabilizers do not contain metallic element, are current novel environment friendly heat stabilizer research and development focus.
As other chemicals, the production application of traditional heat stabilizer also can endanger human health and human survival
Environment.So, people start to start exploitation popularization non-toxic heat stabilizer to replace the upsurge of traditional poisonous kind.Among these with
The heat stabilizer that organic compound is entirely free of the organic compound base of any metal as main stabilizer represents PVC heat surely
Determine the long term growth direction of agent industry, develop the forefront field that pure organic main stabilizer is thermally-stabilised research and development at present.
Chinese patent CN105315574 A have studied a kind of PVC calcium zinc heat stabilizer and its application, by quinolone zinc salt
Compound composition with quinolone calcium salt, although this PVC calcium zinc heat stabilizer has good thermal stability, and preferably
Antibacterial surface function, but this technique productions high cost, unsuitable industrialized production.In existing numerous organic heat stabilizers,
Most of only have absorption HCl, be complexed the functions such as the metal chloride with catalysis PVC degraded.However, PVC heat stabilizer
In the middle of function, the ability replacing unstable chlorine atom is only most critical.Absorb the degraded that the abilities such as HCl can only delay PVC, and
Replacement unstable chlorine atomic energy eliminates at the very start and causes PVC degradation factors to stop PVC from degrading.Although what oneself developed at present contains
The ability that nitrogen type thermal stabilizing agent replaces unstable chlorine atom is weaker, also cannot use as main stabilizer, but it has remained
The most potential kind developing into main stabilizer in machine heat stabilizer.
Lead salt stabilizer is that in the middle of all stabilizers, cost performance highest is a kind of, and always in occupation of leading position,
Due to its excellent transparency, good initial coloring is also frequently used European good fortune soaps stabilizer.In whole world green
Under the pressure of peace movement, because lead, good fortune class stabilizer are poisonous and its significant damage that environment is caused, countries in the world go out one after another
The platform new measure, limits or forbids the use of lead, cadmium stabilizer in PVC production process, and the process to PVC discarded object is formulated
Strict regulations.
There are some researches show, Chinese patent CN101901076A with fatty alcohol or organic acid, acylate, epoxidized soybean oil,
Micro-nano metal and sepiolite or inorganic non-metallic breeze, the stabilizer of composition, this stabilizer removes has conventional stabilizer
Stabilization outside, also to resin converted products, there is toughness reinforcing enhancing, fire-retardant and high-weatherability, but post processing be complicated,
Energy consumption is excessive, is unfavorable for cost-effective.Calcium zinc heat stabilizer is typical case's generation of nonhazardous auxiliary agent in polyvinyl chloride (PVC) industry
Table.And, compared with organo-tin het stabilizer, calcium zinc is generally tasteless, the relatively low advantage of cost.Thus, become PVC Auxiliaries Industry
Important research field.One of research contents of calcium zinc heat stabilizer is to improve it to thermal stability of both PVC simultaneously:Just
Phase tinctorial property and drastically aging (" the zinc burning ") in later stage.
The present invention describes a kind of zinc-containing raw materials use being formed with cyanuric acid zinc/efficient PVC stabilizer of urea pyrimidine zinc Compositional type
To improve PVC thermal stability, this application scheme has no that relevant document discloses.

The heat endurance of cyanuric acid zinc/urea pyrimidine zinc characterizes：
Characterize the thermal decomposition behavior of cyanuric acid zinc/efficient PVC stabilizer of urea pyrimidine zinc Compositional type, result using thermogravimetric analyzer
As shown in Figure 1.
Brief description：
Fig. 1. the heat endurance of cyanuric acid zinc/efficient PVC stabilizer of urea pyrimidine zinc Compositional type characterizes
As seen from the figure, the efficient PVC stabilizer that cyanuric acid zinc/urea pyrimidine zinc compounds has a little micro- in 25-300 DEG C of temperature range
Little weightlessness, this is to be caused by some the absorption water volatilizations in sample.Find out from ensuing TGA curve trend, from 310 DEG C
Start to decompose, its decomposable process can be divided mainly into two stages.The decomposition of first stage is in 310-490 DEG C of this temperature range
Inside carry out, mainly decompose the carbon monoxide having volatilized three molecules, weight loss is about 15.1% (calculated value is 15.9%).
The weightless of second stage sample 21.3% occurs in 490-800 DEG C of this temperature range, and mainly remaining cyanuric acid is organic
The decomposition volatilization (calculated value is 22.7%) of thing part.The residue that sample finally decomposes remaining 63.4% is that Zn0 is (theoretical
Clearing are worth for 61.4%).From here it can also be seen that, the cyanuric acid zinc above being drawn substantially conforms to actual conditions.The opposing party
Face, the efficient PVC stabilizer that cyanuric acid zinc/urea pyrimidine zinc compounds just starts to decompose from 310 DEG C, can protect in PVC process
It is fixed to keep steady, and meets the primary condition as PVC heat stabilizer.
