Abstract
The invention discloses an auxiliary heat stabilizer of organic tin. The auxiliary heat stabilizer is characterized in that mercaptan reacts with sulphur with organic amine as a catalyst, so as to generate disulfide and a byproduct hydrogen sulfide; the disulfide is taken to be compounded with a universal PVC (polyvinyl chloride) stabilizer, so as to obtain the stabilizer. The stabilizer disclosed by the invention is stable in structure, simple in process, convenient to operate, synergistic in effect and significant in effect.
Description
Technical field
The present invention relates to stablizer, be specifically related to organotin auxiliary heat stabilizer.
Background technology
Polyvinyl chloride (PVC) resin as its consumption of world's second largest synthetic resins in recent years also at the speed rapid growth with annual 4%, and the structures shape of PVC self its thermal destruction and easy aging feature, its processing temperature (180 ℃) is far above its decomposition temperature (120-130 ℃) simultaneously, this just determines must add thermo-stabilizer in the machine-shaping process of PVC goods, stablizer, as the limitation due to aspects such as its performance and prices such as lead, tin, becomes clear day by day to the restriction of market and economic benefits.In order to meet society, market and economic requirement, the development of stablizer must be towards nontoxic, efficient future development.
In PVC processing thermal stabilizer component, sulphur content height has determined that whole product stability can be fine or not to a great extent, and it is high to reaction and processing requirement directly to introduce active sulphur in main stabilizer, existing method is to add the auxiliary stabilizer that contains active sulphur, and the auxiliary stabilizer that can use as active sulphur component is at present less.
At present, the stabilization that PVC thermo-stabilizer industry plays the component of interpolation sulfur-bearing is reached common understanding already, just adding the sulphur of which kind of structure and how preparing the sulphur that this synergy is good is the direction that everybody makes great efforts always, and almost there is no ripe product on market.
Summary of the invention
The object of the invention is to: a kind of organotin auxiliary heat stabilizer is provided, Stability Analysis of Structures, technique is easy to control, can either promote as auxiliary stabilizer the active sulphur content of whole stabilizer component, also can guarantee the effect of other parts of component, while synergistic effect is together also very good.
Technical solution of the present invention is: it is that mercaptan be take organic amine as catalyzer reacts with sulphur, generates double thioether and by product hydrogen sulfide; Get double thioether and general PVC stablizer and carry out compositely, obtain stablizer.
Wherein, mercaptan is sulfur alcohol, lauryl mercaptan or mercaptoethanol.
Wherein, organic amine is methane amide or isobutyramide.
Wherein, reaction formula is as follows:
2R-SH+2S---organic amine----R-S-S-S-R+H
2s,
The general PVC stablizer of R-S-S-S-R+----stablizer,
R is organic mercaptan.
Wherein, concrete reactions steps is as follows: in the environment that the mercaptan of getting 1 mole is catalyzer at organic amine, react at 60-100 ℃ with the sulphur of 1 mole, until H
2s gaseous emission is complete, filters and takes out double thioether; This double thioether mixes according to different proportionings as required from general PVC stablizer, obtains the finished product stablizer.
The contrast of the present invention and prior art: Stability Analysis of Structures, technique is simple, easy to operate, synergy, effect is remarkable.
Accompanying drawing explanation
Fig. 1 is that stablizer is for the photo comparison diagram of PVC processing.
Fig. 2 is that stablizer is for the graphic representation of PVC processing.
Embodiment
Below in conjunction with specific embodiment, further illustrate technical solution of the present invention, these embodiment can not be interpreted as it is the restriction to technical scheme.
Embodiment 1: in the environment that the sulfur alcohol of getting 1 mole is catalyzer at methane amide, react at 60 ℃ with the sulphur of 1 mole, until H
2s gaseous emission is complete, filters and takes out double thioether; This double thioether regulates tin content to mix with general organotin stabilizer T181 as required, obtains the finished product stablizer.
Embodiment 2: in the environment that the lauryl mercaptan of getting 1 mole is catalyzer at methane amide, react at 80 ℃ with the sulphur of 1 mole, until H
2s gaseous emission is complete, filters and takes out double thioether; This double thioether regulates tin content to mix with general organotin stabilizer T181 as required, obtains the finished product stablizer.
Embodiment 3: in the environment that the mercaptoethanol of getting 1 mole is catalyzer at isobutyramide, react at 100 ℃ with the sulphur of 1 mole, until H
2s gaseous emission is complete, filters and takes out double thioether; This double thioether regulates tin content to mix with general organotin T181 as required, obtains the finished product stablizer.
The stablizer of embodiment 1-2 gained is for PVC processing, and the photo of PVC goods as shown in Figure 1, 2.
