Description
Technical field
The invention belongs to PVC stabilizer technical field, relate to a kind of PVC reinforcer and production technique thereof.
Background technology
PVC is the general-purpose plastics that a class is widely used in the fields such as building, light industry, chemical industry, electronics, space flight, automobile, agricultural.The disadvantage of PVC is poor heat stability.In order to suppress the degraded of PVC in the course of processing, usually need to add thermo-stabilizer in the PVC course of processing.The thermo-stabilizer principal item of current application is lead salt stabilizer, organic tin stablizer, metal soap stablizer etc.Because lead salt stabilizer has larger superiority in stability and cost etc., be therefore all the first-selection of PVC product thermo-stabilizer all the time, in current domestic PVC processing large mainly with lead salt as stablizer.Along with the progress of society, the raising of people's living standard, health requirements, and the enhancing of global environmental consciousness, Lead contamination be day by day subject to people pay close attention to, a lot of field oneself come into effect prohibit plumbous scheme.On January 27th, 2003, European Union oneself formally disclose " scrapping electronic and electrical equipment instruction " (WEEE) and < prohibits the use some Hazardous Substances Directive about at electronic electric equipment " (ROHS).In May, 2006, ESPA and EuPC joint commitments European Union completely forbade in 2015 and uses leaded PVC stabilizer, and European Union prohibits the use containing cadmium stabilizer at the end of 2006.Therefore worldwide nontoxic, pollution-free, compound and efficiently become the irreversible development trend of PVC heat stabilizer, and Ca/Zn thermo-stabilizer is nontoxic, the environment-benign heat stabilizer of generally acknowledging in the world, and there is the advantages such as cheap, oilness is good, there is extremely wide development space.
In recent years, produce calcium-zinc composite stabilizing agent and mainly contain two kinds of methods: one adopts metathesis to produce, first in stearic acid, add caustic soda carry out combined reaction, add metal-salt again and carry out replacement(metathesis)reaction, hard calcium or the hard zinc of monomer is formed after dehydration, drying, pulverizing, packaging, and then throw in different additive as required, be finally re-dubbed the calcium-zinc composite stabilizing agent of different varieties.Second method be application colter machine or kneader by stearic acid and metal salt catalyst at a certain temperature direct reaction produce hard calcium or the hard zinc of monomer, and then throw in different additive as required, be finally re-dubbed the calcium-zinc composite stabilizing agent of different varieties.But these two kinds of methods all defectiveness, first method operation is many, successively will complete in several still, and labour intensity is large, and the poor stability of product, water consumption, power consumption, consumption gas, cost is higher.Although second method decreases operation than first method, but still it is more to there is operation, water consumption, power consumption, consumption gas, and cost is higher, the problem that quality is stable not.
