Abstract
The invention discloses a high-efficiency rare-earth/zinc composite heat stabilizer, which mainly consists of 40 to 95 parts of dicarboxylic acid rare earth salts and 5 to 60 parts of organic acid zinc, and 5 to 40 percent of fatty acid rare earth salts and/or 5 to 30 parts of organic acid calcium. Compared with the prior art, the dicarboxylic acid rare earth salts and the organic acid zinc are adopted as the main raw materials, so the prepared product has good heat stability, no toxicity and no pollution, and has high efficiency, low cost, environment protection and high performance.
Description
Technical field
The present invention relates to a kind of efficient rare-earth/Zn composite heat stabilizer, especially relate to efficient rare-earth/Zn composite heat stabilizer that PVC uses.
Background technology
Polyvinyl chloride (PVC) is as one of five big general-purpose plastics, and its deadly defect is that the thermostability in the processing is relatively poor, processes one of indispensable important auxiliary agent so thermo-stabilizer is PVC.Thermo-stabilizer commonly used has lead salts, metallic soap class, organic tin and calcium/zinc class stablizer in the PVC course of processing at present.There are heavy metal contamination in lead salts and metallic soap class stablizer, are detrimental to health; The organic tin stabilizing agent dosage is less, and the transparency of goods is high, but a lot of organo-tin het stabilizers has peculiar smell, and organotin is harmful to human central nervous simultaneously; Calcium/zinc class stablizer is nontoxic, the environment-friendly type thermo-stabilizer of generally acknowledging in the world, but its thermally-stabilised efficient problem of unstable is difficult to solve always; And the early stage easy coloring of single rare earth class thermo-stabilizer.Therefore, exploitation low toxicity, efficient, inexpensive environmentally friendly thermo-stabilizer have become one of the research focus in current thermo-stabilizer field.
Summary of the invention
The objective of the invention is to: a kind of efficient rare-earth/Zn composite heat stabilizer is provided, and the thermostable effect of this thermo-stabilizer is good and nontoxic, pollution-free.

According to listed as parts by weight, preferred efficient rare-earth/Zn composite heat stabilizer is made up of 40～95 parts of binary organic acid rare-earth saltss, 5～60 parts of organic acid zinc and 5～60 portions of fatty acid rare earth salt and/or 5～30 parts of calcium of organic acid.
Aforesaid binary organic acid rare-earth salts carbon atom quantity is 11～20.
Aforesaid binary organic acid rare-earth salts is one or more in the binary organic acid lanthanide rare salt.Described lanthanide rare is preferably lanthanum and/or cerium.
Aforesaid organic acid zinc is monobasic or binary organic acid zinc.
Aforesaid fatty acid rare earth salt is one or more in the lipid acid lanthanide rare salt.Described lanthanide rare is preferably lanthanum and/or cerium.
Aforesaid calcium of organic acid is monobasic or binary organic acid calcium.
Compared with prior art, the present invention is a main raw material with binary organic acid rare-earth salts and organic acid zinc, and prepared product thermostable effect is good and nontoxic, pollution-free, is a kind of efficient, inexpensive environmentally friendly high-performance thermo-stabilizer.
