Description
Technical field
The invention belongs to chemical stabilizer technical fields, more particularly, to a kind of calcium-zinc composite stabilizing agent and its preparation
Methods and applications.
Background technique
Well known heat stabilizer mainly has lead salts, metal soap, organic tin, terres rares and Ca/Zn class in PVC industry
Equal stabilizers, but the most heat stabilizer of application is lead salts and metal soap.Lead salt stabilizer is cheap, thermostabilization effect
Fruit is good, but its toxicity is big, seriously endangers human health and simultaneously pollutes environment, and lead salt stabilizer have the shortcomings that it is opaque.Have
Machine the tin stabilizer not only transparency and good thermal stability, but also small toxicity, it is widely used in high grade of transparency polyvinyl chloride
Plate, sheet material, food, in medical packaging, but it is expensive, and some products will control in toxicity entirely without poison ring
It protects, thus it is using also restrained.
Raising with society to environmental consciousness, and the raising to the requirement of heat stabilizer comprehensive performance, heat stabilizer
Production and consumption develops to nontoxic, the pollution-free, high grade of transparency, the good and efficient direction of heat resistance.And nontoxic calcium zinc compound thermal
Stabilizer is universally acknowledged nontoxic, environment-benign heat stabilizer, and has many advantages, such as that cheap, lubricity is good, has pole
Wide development space.
However, the plasticizer that existing calcium-zinc composite stabilizing agent uses, for a long time based on mainly adjacent benzene-type products, but
As the adjacent benzene class plasticizer such as DOP, DINP is using more and more extensive, its toxicity is also increasingly subject to insider and consumer
Concern.Neighbour's benzene class plasticizer such as DOP, DINP is the organic matter containing benzene, to the toxic effect of human reproductive system, while having research
Show that such compound has the harm such as carcinogenic, teratogenesis, 6 kinds of DOP, DEHP, BBP etc. are classified as excellent by American National Environmental Protection Agency (EPA)
The toxic pollutant first controlled is forbidden applying in the materials such as medical treatment, food, the numerous and confused response green environmental protection concept of overseas enterprise,
Corresponding laws and regulations are constantly put into effect, the technical barrier to home products is increased.
Summary of the invention
For deficiency existing for calcium zinc stabilizer in the prior art, it is multiple that the purpose of the present invention is to provide a kind of new calcium zinc
Close stabilizer.The novel calcium-zinc composite stabilizing agent is compound using novel non-toxic environmental protection in a creative way under specific calcium zinc salt proportion
Plasticizer obtains colourless transparent liquid calcium zinc stabilizer.
Another object of the present invention is to provide a kind of preparation methods of above-mentioned calcium-zinc composite stabilizing agent.Side of the present invention

And chlorinated rubber etc. has good intermiscibility.Meanwhile it is also widely used for food packaging, medical apparatus, toy for children, individual
Amenities, PVC are granulated, and ward off glue rubber patch product, cigarette filter etc..
TXIB, for the double isobutyrates of 2,2,4- trimethyl -1,3- pentanediols of Eastman company, U.S. production, molecular formula is
C16H30O4, it is a kind of primary plasticizer, is non-neighboring benzene class environment-friendly plasticizer, with all general primary and secondary plasticizer phases
Hold, is widely used in PVC plastic colloidal sol and organosol, and its chemical property is stablized, and is not easy to be mixed into bubble, energy in the solution
Keep product it is smooth with it is beautiful, be a kind of with plasticization and lower volatile thinner, it is good product can be assigned
Cold resistance and water resistance.
Therefore, the present invention is using DINCH, TXIB and ATBC as plasticizer, and wherein TXIB, DINCH viscosity are lower,
The viscosity that batching system can be reduced reduces the use of thinner；ATBC oil resistivity, light resistance, fungus resistance are splendid, with TXIB,
DINCH be used in compounding can be improved PVC product have many advantages, such as low temperature flex performance and sealing when thermal stability it is good, non-discolouring.
