Technical field
The present invention relates to complex stabilizer, refers in particular to a kind of suitable making plastic pipe system that for example tubing such as pvc pipe, PE pipes is used
Plastic tube calcium-zinc composite stabilizing agent and preparation method thereof.
Background technology
PVC, PE are the maximum general-purpose plastics of yield and consumption.The yield of world PVC more than 100,000,000 tons, China 17,800,000
Ton.Due to PVC heat stability difference and processing difficulties, 4% or so heat stabilizer, China must be added in processing and forming
It is annual to consume about 700,000 tons of heat stabilizer.Traditionally heat stabilizer is based on lead salt type thermal stabilizing agent, due to lead salt stabilizer
Toxicity it is stronger, with bioaccumulation, and easily generate dust, therefore, operator can be caused during production and use
There is chronic lead poisoning in member, and can cause serious environmental pollution after discarding.With the raising of people's environmental consciousness, especially Europe
Alliance RoHS and WEEE instruction and the U.S., Japan, Korea have also launched respectively relevant laws and regulations, and environmental protection organization of the world proposed already
To forbid the use of lead heat stabilizer in the whole world at 2015 or so；The departments such as the Ministry of Information Industry of China, State Development and Reform Commission combine
Formulate《Electronics and IT products pollution control management method》, the ministries and commissions such as National Development and Reform Committee, the Ministry of Construction, Ministry of Public Health joint is hereafter tight
Prohibit the lead salt stabilizer used in national each upper hose material, while having put into effect multinomial relevant national standard in succession.In the market
There is leaded, cadmium heat stabilizer the succedaneum of series such as in Jing：Ca/Zn complex stabilizer, rare-earth stabilizer, organic tin stabilizer.
Wherein, calcium zinc heat stabilizer due to it is nontoxic, efficient the characteristics of so as to become most active neck in complex stabilizer in recent years
Domain and most competitive product.But calcium zinc heat stabilizer still suffers from the defects such as poor stablizing effect, initial coloration, " zinc burning ",
Application effect is undesirable, it is difficult to replace Lead salt thermal stabilizer, needs auxiliary heat stabilizer synergism.
Composite type heat stabilizer is due to the trend that excellent performance and good environmental-protecting performance are development, but existing composite type heat
Stabilizer (such as lead salt complex stabilizer, organic tin stabilizer), production cost is higher, containing certain toxicity, production process
In can produce toxic waste, waste gas, to environment, impact is produced on the health of human body.
