Description
SkillThe art field
The invention belongs to the polymer modification technical field, be specifically related to a kind of nontoxic, heat resistanceheat resistant and shrink PVC material and ME thereof.
The back of the bodyThe scape technology
SE (PVC) is as one of resins for universal use, and it is good to have an intensity height, corrosion-resistant, good insulating, resistive ability, and cheap, advantage such as raw material sources are extensive, and is widely used in industries such as building, electric power, device, agricultural, PW.In recent years, the world steady growth trend still occurs to the aggregate demand of PVC.Modification can not only be given PVC material special performances, also possibly improve its processing ability and other physicals significantly.Along with people's is increasingly high and require refinement day by day to specific function to material performance requirement; Current nearly all PVC goods all will be equipped with corresponding adjuvants; Form functional article through specific process and formula technique, comprising soft goods such as hard article such as sheet material, tubing, pipe fitting, profiled material and film, pipe, footwear, toy, CABLE MATERIALS, leatheroids.
PVC is typical thermally sensitive resin, and its flow temperature is 136 ℃, and decomposition temperature is 140 ℃, and its worker's temperature is often all more than 170 ℃.In order to make product have excellent performance, must add thermally-stabilised and/or auxiliary heat stabilizer, its consumption is little, and effect but holds the balance.The hot of PVC material mainly comprises: many indexs such as heat-drawn wire, long-term heat resisting temperature, soldering resistance, melting index, shrinking percentage.
The lead salts thermo-stabilizer is a principal item in the PVC thermo-stabilizer with its inexpensive and excellent thermostability for a long time.In addition, the thermo-stabilizer that contains cadmium, barium also is applied in the PVC thermo-stabilizer because of its good thermostability and collaborative stability.But, admitted by people because heavy metals such as cadmium, barium, are prohibited toxic metal such as lead, cadmium, barium to the murder by poisoning of human body with to severe environmental pollution property.The electronics and IT products pollution control management way that began to carry out in 2007 " clearly proposition taboo lead.But the PVC processing that China is present is main with lead salt and cadmium salt still, runs counter to environmental requirement, adjusts extremely urgent.
