Description
Technical field
The present invention relates to a kind of hydrotalcite composite heat stabilizer and application thereof.
Background technology
Therefore the Halogen polyolefine can take off the self-catalyzed reaction of HCl under illumination or heating state, directly cause goods to darken, and structure and performance are suffered great destruction, in the course of processing, must add thermo-stabilizer, to stop or to delay its degraded.
Thermo-stabilizer commonly used comprises lead salts, metallic soap class, organic tin, composite thermal stabilizer and other auxiliary agents etc.Lead salts thermo-stabilizer thermostable effect is good, and electrical insulating property and weather resisteant are good, low price; But it is plumbous poisonous; Not only in the product relevant, use and be restricted with food, and the raising of Along with people's environmental consciousness, almost the application in all products all is restricted.In addition, the lead salt thermo-stabilizer also receives the pollution of sulphur easily and lost efficacy.The metallic soap class is generally the stearate of calcium metal, barium, good fortune etc., and thermal stability is general, and in them some are also poisonous.The polyolefinic consistency of organotin and Halogen is better, but costs an arm and a leg.Therefore, the development and application of efficient, nontoxic, cheap thermo-stabilizer has crucial meaning for processing and study on the modification.
The hydrotalcite thermo-stabilizer is a type thermal stabilizing agent of studying angle at present as one of novel thermo-stabilizer.As far back as 1980, Japanese Kyowa chemical company just took the lead in hydrotalcite is filled among the PVC, made the steady time lengthening of PVC heat.Research is learnt; Hydrotalcite mainly is because it can absorb a large amount of heat when decomposes to the polyolefinic thermostable effect of Halogen; Thereby reduce the temperature of material surface; Decompose the water and the carbonic acid gas that produce and can play isolated effect again, decompose the material that produces and also can form layer protecting film, thereby reach the effect of protection at material surface.
Yet even heat-stable time is still very short after the single binary hydrotalcite thermal stabilizer modification commonly used, be prone to flavescence early stage after heating, and the later stage is prone to blackout.Though the thermal stability through the binary hydrotalcite behind the organic anion intercalation modifying promotes to some extent, the organic ion in the preparation process all is poisonous mostly or the material of irritating smell is arranged.The difficult control of polywater talcum synthesis condition.What research at present was hot is the hydrotalcite of synthesizing rare-earth class, yet Chinese rare earth reserves have slumped 37% in the period of 1996 to 2009, only surplus 2,700 ten thousand tons.By existing production rate, in China, heavy type of rare earth deposit only can keep 15 to 20 years.Therefore, employing is rare earth modified neither long-term plan.And after hydrotalcite adds the Halogen polyolefine, can cause viscosity increase, the moment of torsion of compounding flux to become big, cause processing difficulties because of the introducing of the laminated structure of hydrotalcite.
Summary of the invention
The purpose of this invention is to provide a kind of efficient, nontoxic, cheap, preparation technology simple, with the methods for making and using same of the good hydrotalcite composite heat stabilizer of the compatible performance of Halogen polyolefine.This composite thermal stabilizer not only need not used rare earth material; Solved shortcomings such as traditional hot stablizer common toxic, costliness, tint permanence are poor, heat-stable time is short, and add can not occur that compounding flux viscosity increases behind the Halogen polyolefine, moment of torsion becomes problem such as big.
A kind of hydrotalcite composite heat stabilizer is characterized in that: contain hydrotalcite, auxiliary heat stabilizer, lubricant, terephthaldehyde's acid metal salt.The application of terephthaldehyde's acid metal salt in hydrotalcite composite heat stabilizer do not report that it at high temperature was difficult for decomposition reaction takes place, and it is more even to make that thermo-stabilizer disperses in the Halogen polyolefine material, makes thermostable effect better.
The object of the invention is realized in the following manner: a kind of hydrotalcite composite heat stabilizer is characterized in that: the binary hydrotalcite, terephthaldehyde's acid metal salt, lubricant and the beta-diketone compounds that contain surface-treated.
As preferably, each constituent mass per-cent is: binary hydrotalcite 10%-60%, terephthaldehyde's acid metal salt 5%-65%, lubricant 15%-35% and beta-diketone compounds 5%-25%.
The binary hydrotalcite of surface-treated is for through one or more the mixture in the zinc-aluminium hydrotalcite of StNa surface-treated, magnesium aluminum-hydrotalcite, calcium zinc hydrotalcite, calcium magnesium hydrotalcite, calcium aluminum hydrotalcite, the zinc-magnesium hydrotalcite.
The preferred terephthalic acid calcium of described terephthaldehyde's acid metal salt, terephthalic acid magnesium, terephthalic acid zinc, potassium terephthalate, para-phthalic sodium, terephthalic acid barium, terephthalic acid aluminium, terephthalic acid iron.Said lubricant is one or more in paraffin, polyethylene wax, the Triple Pressed Stearic Acid.
Described beta-diketone compounds is stearoyl benzoyl methane, diphenylpropane-1,3-dione(DPPO), isobutyl phenyl ketone formyl methane, decoyl benzoyl methane.
The binary hydrotalcite of surface-treated is with adding 30-50 part water in 1 part of binary hydrotalcite, be warming up to 60 ℃～100 ℃, add 0.4%～5% StNa, stirred 1～4 hour, washing, filtering and drying, binary hydrotalcite that must be after modification.
Binary hydrotalcite after a kind of Halogen polyolefine uses hydrotalcite composite heat stabilizer as modification and terephthaldehyde's acid metal salt, beta-diketone compounds thorough mixing in reaction kettle; Move to the kneader heated and stirred behind the thorough mixing; Add lubricant; Mediate 20min at 80 ℃～100 ℃, the discharging compressing tablet makes.
The application characteristic of this stablizer with; In the Halogen polyolefin powder of 100 parts (by weight); Add 30～60 parts of (by weight) softening agent, like dinoctyl phthalate (DOP), 0.2～5.5 part of (by weight) composite thermal stabilizer; Mixed at high speed 4～5min, mixing 4～5min gets final product in two roller mills of 160 ℃～200 ℃.
The advantage of the invention:
1, through the Halogen polyolefine that adds above-mentioned composite thermal stabilizer is carried out the static heat senile experiment, the result shows that composite thermal stabilizer provided by the present invention can effectively improve the polyolefinic thermostability of Halogen.Under 180 ± 1 ℃ of environment, the Halogen polyolefine shows higher initial coloring, and the steady time of heat is more than 100～220min.
2, gained composite thermal stabilizer of the present invention and Halogen polyolefine intermiscibility are good, have good processing properties.
3, gained composite thermal stabilizer of the present invention has good plasticizing capacity, can not increase compounding flux viscosity, can effectively reduce the plastics moment of torsion.
4, the composite thermal stabilizer of gained of the present invention is nontoxic pollution-free from the material to the process.
