Description
Technical field
The present invention relates to the production technical field of heat stabilizer, more particularly to a kind of calcium-zinc composite stabilizing agent production system and
Its production technology.
Background technology
PVC, PE are the general-purpose plastics of yield and dosage maximum.World PVC yield is more than 100,000,000 tons, China 17,800,000
Ton.Because PVC heat endurances are poor and processing difficulties, 4% or so heat stabilizer must be added in processing and forming, China is annual
Consume about 700,000 tons of heat stabilizer.
Traditionally heat stabilizer is based on lead salt type thermal stabilizing agent, because the toxicity of lead salt stabilizer is stronger, has life
Thing accumulation property, and dust is easily generated, therefore, it can cause operating personnel that chronic lead poisoning occurs in the production and use process,
And serious environmental pollution can be caused after discarding.With the improvement of people's environmental awareness, especially European Union RoHS and WEEE instructions
And the U.S., Japan, South Korea have also launched respectively relevant laws and regulations, environmental protection organization of the world had proposed already will be at 2015 or so in the whole world
Forbid the use of lead heat stabilizer；The departments such as the Ministry of Information Industry of China, State Development and Reform Commission joint is formulated《Electronics and IT products pollute
Control management method》, the ministries and commissions such as National Development and Reform Committee, the Ministry of Construction, Ministry of Public Health joint hereafter forbids to make in each upper hose material in the whole nation
With lead salt stabilizer, while multinomial relevant national standard is put into effect in succession.It is hot steady to have occurred the leaded, cadmium of series in the market
Determine the substitute of agent such as：Ca/Zn compound stabilizers, rare-earth stabilizer, organic tin stabilizer.Wherein, calcium zinc heat stabilizer due to
With the characteristics of nontoxic, efficient, most active field and most competitive production in compound stabilizer in recent years are become
Product.But calcium zinc heat stabilizer still suffers from the defects of poor stablizing effect, initial coloration, " zinc burning ", and application effect is undesirable, it is difficult to takes
For Lead salt thermal stabilizer, it is necessary to which auxiliary heat stabilizer acts synergistically.
Through retrieval, Chinese patent application, publication number：CN106565994A, publication date：2017.04.19, one kind is disclosed
Plastic tube calcium-zinc composite stabilizing agent processed and preparation method thereof.The calcium-zinc composite stabilizing agent is made from the following raw materials in parts by weight：
