Description
Technical field the present invention relates to a kind of used thermo-stabilizer and derivative composition thereof of composite thermal stabilizer, particularly polyvinyl chloride that is used to contain the thermoplastic polymer of halogen element.
Background technology is along with the continuous growth of thermoplastic polymer output, and the consumption of its processing aid also increases thereupon.Thermo-stabilizer is mainly used in the processing of polyvinyl chloride (PVC) goods as one of important classification wherein, since prevent that goods in use are heated, the destruction of oxygen and water, thereby prolong work-ing life of goods.
The known polymkeric substance that contains halogen is subject to ultraviolet ray, the influence of light and heat and decomposition reaction takes place, thus destroy its service performance.Resemble polyvinyl chloride especially, easily penetrate, heat in the extrusion moulding process and have under the situation of water and decompose at light, and so decomposition can make that the product mechanical property is aging, coating decomposition etc.For fear of the polymeric decomposition reaction of PVC, just must make the stablizer that is adopted to act on the plasticity polymer for a long time.At present, the thermo-stabilizer that polyvinyl chloride is commonly used can be divided into lead salts, metallic soap class, organic tin, antimony organic, liquid composite stabilizing agent and other auxiliary stabilizer etc.
The lead salts stablizer is the thermo-stabilizer that the PVC goods use the earliest, still uses in a large number now, and cost is low, have good thermostability (can also absorb ultraviolet ray under some situation), particularly long-term thermal stability is good, and electrical insulating property is good, performance with white pigment, sticking power is big, and weathering resistance is good, but is not suitable for being used in the occasion that requires not have sulphur pollution, and not anti-sulfuration, have toxicity, consistency and dispersiveness are slightly poor, and resulting product is opaque.
Organotin also is highly effective thermo-stabilizer, can make transparent article keep very high transparency and consumption minimum, most of organotin is poisonous, but some organo-tin het stabilizer based on the dioctyl tin compound still allow as with the stablizer of Food Contact product because their toxicity is lower and anti-dissolubility is fine.Thiol organotin is the dialkyl group thiol organotin particularly, is that stabilising effect is best in the existing thermo-stabilizer, and it is applicable to all types and other PVC of level, but, cost is than higher, and thiol organotin is incompatible with the lead salt stable product, and both mixing can cause the blackening of material color.
Metal soap thermal stabilizers uses with multiple metallic soap compound form usually, and composition metal stablizer commonly used is Ba/Cd and Ba/Cd/Zn stabilising system.The existing liquid product of this stable system also has solid product, and their main drawback is that stabilising effect is different because of the kind of PVC, precipitate easily in the course of processing, and to the sulphur pollution sensitivity, these then can not take place in containing the Zn system.
Although at present thermo-stabilizer production and the exploitation of China obtain pretty good achievement, compare with advanced international standard and still have many deficiencies and gap greatly.(1) kind is few, unreasonable structure, and the lead salts stabilizer comprises of high poison, high pollution, low grade is according to absolute dominant position, and the organic tin proportion is well below the level of developed countries; (2) industrial scale is little, poor product quality; (3) exploitation dynamics is not enough, and the funds of input are very few; (4) the loaded down with trivial details backwardness of production technique, the duplication of labour, cost strengthens.
As a big kind of general plastic, the output of polyvinyl chloride (PVC) is sure to occupy the prostatitis always in polymer industry, and the development of thermo-stabilizer is closely related with the PVC industrial expansion with production.And under the requirement of international overall situation and environmental legislation, current PVC thermo-stabilizer just develops towards low toxicity-nontoxic and compound direction, seeks a kind of novel thermo-stabilizer and substitutes stablizer poisonous, dust pollution and become the certainty of era development.
EP-B-424572 discloses a kind of modification method of weathering resistance of hard PVC forming composition, specifically is meant by ZnS partly to replace lead and cadmium with TiO2.Though through the PVC goods after the improvement tangible positive effect has been arranged aspect weathering resistance, the heavy metal amount that forms in the Compound P VC goods is to be growing on and on.
In addition, C-3019632 has also described the effect of hydrotalcite in the PVC goods, by structure Mg
