Abstract
The invention discloses an auxiliary heat stabilizer for inhibiting zinc burning in a machining process of PVC (Polyvinyl Chloride). The auxiliary heat stabilizer is pentaerythritol monoester obtained in such a way that one carboxyl group of organic dicarboxylic acid and one hydroxy group of pentaerythritol are subjected to esterification reaction, and keeps the activity of other three carboxyl groups; the general formula of the auxiliary heat stabilizer is as follows: C4(OH)3COO-R-[C4(OH)2COO-R-]nOOC4(OH)3, wherein R is the organic dicarboxylic acid, and n can be 0. The auxiliary heat stabilizer is obtained through the following concrete reaction steps of: reacting 1 mol of the organic dicarboxylic acid and a double amount of pentaerythritol at 180 DEG C for 0.5-4 hours; then cooling to 60 DEG C, keeping the temperature for 30 minutes, filtering, and cooling; finally crushing and spraying powder to obtain the final product stabilizing agent, wherein the ratio of the carboxyl groups of the organic dicarboxylic acid to the hydroxy groups of the pentaerythritol is 1:4. The auxiliary heat stabilizer disclosed by the invention has the advantages of simplified structure, convenience for processing and obvious effect, and can be used as the auxiliary heat stabilizer of calcium, zinc and lead salt.
Description
Technical field
The present invention relates to stablizer, be specifically related to a kind of auxiliary heat stabilizer burnt for suppressing PVC course of processing zinc.
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 characteristics, 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, current stablizer is as the limitation due to aspects such as its performance and prices such as lead, tin, and the restriction of market and economic benefits is become clear day by day.In order to meet society, market and economic requirement, the development of stablizer must be towards nontoxic, efficient future development.
In the thermal stabilizer component of PVC processing at present, the application of organic zinc compound is very general, the organic zinc component can make the primary stability of PVC processing be greatly enhanced, but the lifting along with the organic zinc component concentration, " zinc burning " risk of goods improves greatly, on domestic market, traditional method mainly solves " zinc burning " problem to add calcium stearate, but calcium stearate suppress " zinc burnings " indifferent and in whole system addition larger, this can produce on other components of whole stabiliser system collaborative the impact.Foreign market bis(pentaerythritolester) product as more novel in Japan has can play the effect that substitutes and improve calcium stearate or other calcium salt, but synthesis technique is more complicated, and cost is higher, and the market limitation is larger.
Summary of the invention
The object of the invention is to: a kind of auxiliary heat stabilizer burnt for suppressing PVC course of processing zinc is provided, improve " zinc burning " situation after organic zinc class stablizer zinc content promotes, do not affect the synergy of other components of system when guaranteeing the primary stability of goods, synthesis and preparation process and cost controllability are strong simultaneously.
Technical solution of the present invention is: this auxiliary heat stabilizer is the tetramethylolmethane monoesters obtained by hydroxyl generation esterification on carboxyl of Dicarboxylic Acids and tetramethylolmethane the activity that keeps other three hydroxyls, and its general formula is as follows: C
4(OH)
3cOO-R-[C
4(OH)
2cOO-R-]
noOC
4(OH)
3, wherein R is Dicarboxylic Acids, n can be 0; Concrete reactions steps is as follows: the tetramethylolmethane of 1 mole of Dicarboxylic Acids and doubled amount is at 180 ℃ of reaction 0.5-4 hour; Then be cooled to 60 ℃ of insulations 30 minutes, filter, cooling; Finally, the fragmentation final product stablizer that dusts to obtain; Wherein, the hydroxyl of the carboxyl of Dicarboxylic Acids and tetramethylolmethane is 1:4.
Wherein, organic carboxyl acid is hexanodioic acid or other di-carboxylic acid.
The contrast of the present invention and prior art: designs simplification, easy to process, effect is remarkable, can be used as the auxiliary stabilizer of calcium zinc stabilizer and lead salt stabilizer.
The accompanying drawing explanation
Fig. 1 is the photo contrast of stablizer for PVC processing.
Embodiment
Further illustrate technical solution of the present invention below in conjunction with specific embodiment, these embodiment can not be interpreted as it is the restriction to technical scheme.
Embodiment 1: the tetramethylolmethane of 1 mole of hexanodioic acid and 2 moles was 180 ℃ of reactions two hours, be also the carboxyl of hexanodioic acid and the hydroxyl 1:4 of tetramethylolmethane, in stable condition 60 ℃ of insulations 30 minutes that are cooled to after transparent of question response, filter, cooling, be broken into powder and obtain the final product stablizer.
Embodiment 2: the tetramethylolmethane of 1 mole of terephthalic acid and 2 moles is 180 ℃ of reaction half an hour, be also the carboxyl of terephthalic acid and the hydroxyl 1:4 of tetramethylolmethane, in stable condition 60 ℃ of insulations 30 minutes that are cooled to after transparent of question response, filter, cooling, be broken into powder and obtain the final product stablizer.
Embodiment 3: the tetramethylolmethane of 1 mole of hexanodioic acid and 2 moles was 180 ℃ of reactions four hours, be also the carboxyl of hexanodioic acid and the hydroxyl 1:4 of tetramethylolmethane, in stable condition 60 ℃ of insulations 30 minutes that are cooled to after transparent of question response, filter, cooling, be broken into powder and obtain the final product stablizer.
The stablizer that embodiment 1-2 obtains is processed for PVC, and PVC goods photo as shown in Figure 1.
