Description
Technical field
The present invention relates to stabilizer law technology field, more particularly to a kind of organic transparent composite thermal stabilizer preparation and its
Using.
Background technique
Heat stabilizer is one of important class in plastic processing additives, and the birth and development of heat stabilizer and polyvinyl chloride resin are same
Step is mainly used in polyvinyl chloride resin processing, therefore the ratio of soft or hard product has close pass in heat stabilizer and PVC resin, PVC
System.
Polyvinyl chloride (PVC) is one of big resins for universal use in the world five, and one of industrialized resin earliest, and annual output is only
Inferior to polyethylene, because it has excellent performance, it is cheap due to be widely used in the every field of people's life.With China's economy
Rapid development, increasingly increase severely to the demand of PVC.Practical application is put into till now since the 1930s, PVC's
First is occupy always in plastics processing industry using yield.But it restricts PVC and widens the greatest problem of application field just
It is its poor thermal stability, by measuring, the results show that PVC just has begun in 140 DEG C, generation is obvious to be decomposed, and its
Melt processing temperature at least will be at 160 DEG C or more, that is to say, that and PVC is also not up to molten condition and just has begun decomposition, this
Seriously constrain the machine-shaping of PVC.Therefore, it must be added to heat stabilizer in PVC processed and applied.
Current industrialized PVC heat stabilizer mainly has lead salts, metal soap, organic tin, antimony organic class, dilute
Great soil group and organic auxiliary heat stabilizer.Though these stabilizers have the advantages that it is respective, there is it is toxic or it is expensive with
And the disadvantages such as the transparency is poor, stabilization efficiency is low.In order to make PVC be preferably applied for transparent article field, increase the beauty of PVC product
The property seen is studied transparent, environmentally friendly, reasonable price the PVC composite heat stabilizer of one kind and is had a good application prospect.
It must be added to heat stabilizer in the process of PVC.Common PVC transparent heat stabilizer is organic tin PVC
Heat stabilizer etc., but the type thermal stabilizing agent is expensive, product part is toxic and is not easily recycled, for this purpose, correlative technology field
Technical staff this is improved, as to be that CN201710628863.7 is proposed " a kind of organic for Chinese Patent Application No.
The preparation and its application of bright composite thermal stabilizer ", in this application file, due to 3- amino-1,2,4-triazole and stearic acid
The collaboration stablizing effect of zinc, prepared PVC piece have good light transmittance and lower mist degree；3- amino-1,2,4-triazole
With very strong coordination ability, with zinc chloride can effectively be complexed in the compounding of zinc stearate, to effectively delay zinc
It burns, improves the long-term thermal stability performance of PVC product；Epoxide and phosphite ester compound are as auxiliary heat stabilizer
For further improving PVC product long-term thermal stability in 3- amino-1,2,4-triazole/zinc stearate.Meanwhile epoxidation
The introducing for closing object and phosphite ester compound, also substantially increases the transparency of PVC product, but the skill in this application file
Art scheme appoints right Shortcomings, and the preparation condition and difficulty such as main stabilizer are larger, for this purpose, we have proposed a kind of organic transparent
The preparation and its application of composite thermal stabilizer.
