Description
Technical field
The present invention relates to a kind of heterogeneous system uracil carboxylic acid zinc PVC stabilizer novel preparation method, according to the present invention
Heterogeneous system prepares new application of the uracil zinc polycarboxylate in terms of PVC thermal stabilities.
Background technology
Polyvinyl chloride accounts for the 40% of whole plastics consumption, is that yield is only second to the Equations of The Second Kind modeling of polyethylene in the world at present
Material product.But its thermal stability is poor, it is necessary to add a certain amount of heat stabilizer ability machine-shaping, to prevent or slow down PVC
Thermal degradation in process, further, it is also possible to prevent PVC product in use because the destruction that light, heat, oxygen cause is made
With keeping its physical property.Conventional PVC heat stabilizer contains metal ion with lead salts, metal soap, organic tin etc. at present
Heat stabilizer based on.With the enhancing of mankind's environmental consciousness, research and development Environment-friendlyheat heat stabilizer is just being started both at home and abroad to replace
The upsurge of traditional non-environmental protection kind.
As other chemicals, the production application of traditional heat stabilizer can also endanger human health and human survival
Environment.So, people start to start exploitation popularization non-toxic heat stabilizer to replace the upsurge of traditional poisonous kind.In this heat
In tide, the poisonous heat stabilizer such as traditional leaded, barium gradually will fade out market, and the heat of the zinc-base of environment-friendly type and organic compound base
Stabilizer will obtain the new motive force of development and the market space.It is entirely free of using organic compound as main stabilizer among these and appoints
The heat stabilizer of the organic compound base of what metal represents the long term growth direction of PVC heat stabilizer industry, develops pure organic
Main stabilizer be current thermally-stabilised research and development forefront field.
It is in existing numerous organic heat stabilizers, most of that only there is absorption HCl, complexing with catalysis PVC degradeds
The functions such as metal chloride.However, in the middle of the function of PVC heat stabilizer, replacing the ability of unstable chlorine atom to be only most critical
's.The degraded that the abilities such as HCl can only delay PVC is absorbed, and is replaced unstable chlorine atomic energy to eliminate at the very start and is caused PVC to degrade
Factor is degraded with preventing PVC.So main stabilizer must possess the ability for replacing unstable chlorine atom in PVC chains.Nitrogenous class
Organic heat stabilizers are exactly that a class has the heat stabilizer for replacing unstable chlorine atom ability, although the nitrogenous class that oneself develops at present
Heat stabilizer replaces the ability of unstable chlorine atom weaker, cannot also use as main stabilizer, but it remains organic heat
The most potential kind for developing into main stabilizer in stabilizer.
Calcium zinc heat stabilizer is the Typical Representative of nonhazardous auxiliary agent in polyvinyl chloride (PVC) industry.Also, with organotin heat
Stabilizer is compared, and calcium zinc is generally tasteless, the relatively low advantage of cost.Thus, become the important research field of PVC Auxiliaries Industries.Calcium zinc
One of research contents of heat stabilizer is while improving which to thermal stability of both PVC:Initial coloration performance and later stage
Drastically aging " zinc burning ".
There are some researches show, Chinese patent CN101717551A is prepared for a kind of self-lubricating using organic monoacid rare-earth salts, resist
Xanthochromia, the PVC stabilizer without pit, although the stabilizer has good stablizing effect, but organic monoacid rare-earth salts prepares work
Skill is complicated, and post processing power consumption is larger, relatively costly, it is impossible to industrialize.Zinc compound beyond fatty acid zinc can improve PVC
Thermal stability.For example:Using epoxyoleic acid zinc (Guo Lixin, Wan Qinghong, Cui Yanyan, China Rubber/plastics Technology and equipment, 2006,32
(12):6-9), amino-acid zinc etc. (Li Zhongbao, Liu Xiumei, plastic additive, 2010, No. 2:1-8) etc..
It is zinc-containing raw materials to improve PVC that a kind of heterogeneous system of present invention description prepares the compound of uracil zinc polycarboxylate
Thermal stability, is simplified to preparation technology, and this application scheme has no that relevant document is disclosed.
