Description
Technical field
The present invention relates to a kind of PVC heat stabilizer, particularly to a kind of mesoporous silicon load P VC heat stabilizer and preparation method thereof.
Background technology
Polrvinyl chloride (PVC) is the second largest synthetic resin being only second to polyethylene, is widely used in building, telecommunication, traffic, electricity
The industries such as son, chemical industry, packaging.But PVC poor heat stability, must be added to a certain amount of heat stabilizer to carry in the course of processing
Its heat stability high.Conventional heat stabilizer has lead salt, metal soap, organic tin, terres rares etc..Metal soap is thermally-stabilised
Agent is the second largest class main stabilizer that consumption is only second to lead salt.
According to metallic soap activity in stoping PVC degraded, metallic soap can be divided into two classes: a class is only capable of absorbing hydrogen chloride, anti-
Only its catalytic action to dehydrochlorination reaction, the most representational is barium soap and calcium soap.This kind of metallic soap heat stability is general,
Primary stability is bad, but is heated for a long time, and PVC stability change is little.The chloride generated in its stabilization procedures is to dechlorination
Change hydrogen-based this nothing catalytic action.Another kind of can not only absorbing hydrogen chloride, additionally it is possible to react so that PVC is stable with allyl chloride,
Most represent is cadmium soap and zinc soap.This kind of metallic soap initial coloring is fine, but long-term by hot article drastically variable color.Especially
, easily there is drastically melanism in zinc soap, produces so-called " zinc burning " phenomenon.It is used alone any kind metallic soap, is all extremely difficult to
Satisfied stablizing effect.If by cadmium high for activity, zinc soap and the barium of poor activity, calcium use, then initial coloring and length can be made
Phase stability is all improved.
Mesoporous silicon is a kind of amorphous silicon materials with 2-50nm aperture.Super big hole surface area that mesoporous silicon has, hole body
The features such as long-pending and aperture is homogeneous, narrow ditribution so that it is there is advantage when the heat stabilizer that processability is excellent.
Summary of the invention
It is an object of the invention to: more excellent mesoporous silicon load P VC heat stabilizer of a kind of stability and preparation method thereof is provided.
The technical scheme realizing the object of the invention is: a kind of mesoporous silicon load P VC heat stabilizer, this heat stabilizer is by metallic soap master
Stabilizer and phosphite ester or the auxiliary stabilizer of epoxide, mesoporous silicon, antioxidant, lubricant, fire retardant composition.
Mesoporous silicon load P VC heat stabilizer of the present invention, described mesoporous silicon addition is the 5～10wt% of total formula, preferably

Mesoporous silicon load P VC heat stabilizer of the present invention, each constituent mass percentage ratio is:
Above-mentioned mesoporous silicon load P VC heat stabilizer, described antioxidant be three (2,4-di-tert-butyl-phenyl) phosphite ester, four (2,4-
Di-t-butyl eight alkoxyl-4,4-xenyl) phosphate ester, double (2,4-di-tert-butyl-phenyl) pentaerythritol diphosphites, (2,4,6-
Tri-tert phenyl-2-butyl-2-ethyl)-1,3-diol phosphite, four (2,4-di-tert-butyl-phenyls-4,4 '-xenyl)
Biphosphonate, Distearyl pentaerythritol, trisnonylphenyl phosphite, diphosphorous acid two (tetradecyl alchohol) season
One of Doutrate.
Above-mentioned mesoporous silicon load P VC heat stabilizer, described lubricant for neck phthalic acid glycerol two stearic acid ester, octadecanol,
One of 18 fatty acids, paraffin, Tissuemat E, amide waxe.
Above-mentioned mesoporous silicon load P VC heat stabilizer, described fire retardant is one of magnesium hydroxide, aluminium hydroxide, zinc.
Phosphite ester be phosphorous acid benzene Diisooctyl, phosphorous acid benzene didecyl, triphenyl phosphite, phosphorous acid hexichol isodecyl ester it
One.
Mesoporous silicon load P VC heat stabilizer of the present invention, described each constituent mass percentage ratio is preferably:
Mesoporous silicon load P VC heat stabilizer of the present invention, described each constituent mass percentage ratio is more preferably:
Mesoporous silicon load P VC heat stabilizer of the present invention, described each constituent mass percentage ratio is more preferably:
Mesoporous silicon load P VC heat stabilizer of the present invention, described each constituent mass percentage ratio is more preferably:
The preparation method of mesoporous silicon load P VC heat stabilizer of the present invention, comprises the steps:
(1) zinc stearate, barium stearate, phosphite ester are put in reaction vessel, be heated with stirring to 65～85 DEG C, add
Mesoporous silicon is warming up to 95～105 DEG C again, stirs 20～30min；
(2), before again antioxidant, lubricant, fire retardant being added in step reactant liquor, it is slowly stirred, and is warming up to 110～120 DEG C,
Keep 30～60min, be then filtrated to get mesoporous silicon load P VC heat stabilizer.
The features such as super big hole surface area that mesoporous silicon has, the homogeneous narrow ditribution of pore volume and aperture so that it is excellent in processability
Heat stabilizer time have the advantage that the super big hole volume of mesoporous silicon and specific surface area make it have the biggest adsorption capacity, not only may be used
To be substantially reduced PVC add the HCL concentration in man-hour by self absorption HCL, it is prevented effectively from or subtracts the further degraded of PVC；And
And the main stabilizers such as metallic soap and the co-stabilizer such as phosphite ester, epoxide can be made simultaneously in mesoporous silicon duct with HCL
Enrichment, so that stabilizer faster, preferably play a role, thus can significantly improve the thermostable effect of stabilizer；Additionally,
With great amount of hydroxy group in mesoporous silicon surface and pore passage structure, good synergism can be produced with phosphite ester and cyclohexadione compounds,
Significantly improve the stability of stabilizer.
The present invention has positive effect: the present invention introduces mesoporous silicon in PVC heat stabilizer, the super big hole volume of mesoporous silicon and
Specific surface area makes it have the biggest adsorption capacity, reduces PVC and adds the HCL concentration in man-hour, is prevented effectively from or alleviates entering of PVC
One step degraded；And the main stabilizers such as metallic soap and the co-stabilizer such as phosphite ester, epoxide can be made to exist with HCL simultaneously
Being enriched with in mesoporous silicon duct, so that stabilizer can faster, preferably play a role, thus the heat significantly improving stabilizer is steady
Determine effect.
