Embodiment 1

[0028] This embodiment discloses a PVC composite stabilizer, which is composed of a main stabilizer with a mass fraction of 85-95% and an auxiliary stabilizer with a mass fraction of 5-15%. In this embodiment, the mass fraction can be selected as 60% main stabilizer and mass fraction are 40% auxiliary stabilizer, certainly, also can be the combination in multiple arbitrary ranges, such as mass fraction is the main stabilizer of 70% and mass fraction is the auxiliary stabilizer of 30%, Mass fraction is 75% primary stabilizer and mass fraction is 25% auxiliary stabilizer; primary stabilizer consists of polyvinylpyrrolidone ((C6H9NO)n), zinc pyrrolidonecarboxylate (PCA-Na), disodium edetate Calcium (C 10 h 12 CaN 2 Na 2 o 8 ), tetraisopropyl titanate (C 12 h 28 o 4 Ti), the auxiliary stabilizer is composed of vinyl bis stearamide (C 38 h 76 N 2 o 2 ), pentaerythritol stearate (C 77 h 148 o 8 ), epoxy linseed oil, mannitol (C 6 h 14 o 6 )composition. Among them, ...

Embodiment 2

[0032] Its formula component is with embodiment 1. The difference with Example 1 is that: in the PVC composite stabilizer, polyvinylpyrrolidone ((C6H9NO)n), zinc pyrrolidonecarboxylate (PCA-Na), calcium disodium edetate (C10H12CaN2Na2O8), four The mass fractions of isopropyl titanate (C12H28O4Ti) in the composite stabilizer are: 15%, 25%, 45%, 10%; vinylbisstearamide (C38H76N2O2), pentaerythritol stearate (C77H148O8), The mass fractions of oxygenated linseed oil and mannitol (C6H14O6) in the composite stabilizer are: 1%, 2%, 1%, and 1%, respectively.

[0033] As a further preference, a rare earth stabilizer is added to the PVC composite stabilizer, and the rare earth stabilizer accounts for 6% of the mass of the PVC composite stabilizer, wherein the rare earth stabilizer is yttrium stearate, yttrium maleamate or yttrium isooctanoate. The extra rare earth stabilizer is any one of yttrium stearate, yttrium maleamate or yttrium isooctanoate, or a mixture of yttrium stearate and ...

Embodiment 3

[0037] Its formula component is with embodiment 1. The difference with embodiment 1 is: in this PVC composite stabilizer,

[0038] Polyvinylpyrrolidone ((C6H9NO)n), zinc pyrrolidonecarboxylate (PCA-Na), calcium disodium edetate (C10H12CaN2Na2O8), and tetraisopropyl titanate (C12H28O4Ti) accounted for : 15%, 25%, 35%, 15%; Vinyl bis stearamide (C38H76N2O2), pentaerythritol stearate (C77H148O8), epoxy linseed oil, mannitol (C6H14O6) account for the mass fraction of the composite stabilizer They are: 2%, 3%, 2%, 3%.

[0039] The PVC composite stabilizer is also added with a rare earth stabilizer and modifier indium acetate: the rare earth stabilizer is a mixture of yttrium stearate, yttrium maleamate, and yttrium isooctanoate, and the rare earth stabilizer accounts for 4.2% of the quality of the PVC composite stabilizer. %, its composition and composition ratio are the same as in Example 2. The added modifier indium acetate accounts for 2.2% of the mass of the PVC composite st...

Abstract

The invention provides a PVC compound stabilizer. The PVC compound stabilizer is characterized by being composed of, by mass, 85-90% of a main stabilizing agent and 5-15% of a subsidiary stabilizing agent; the main stabilizing agent is composed of polyvinylpyrrolidone, bis(5-oxo-L-prolinato-N1,O2) zinc, calcium disodium ethylenediamine tetraacetate and titanium tetraisopropanolate, and the subsidiary stabilizing agent is composed of N,N-ethylene bis-stearamide, pentaerythrityl tetrastearate, epoxidized linseed oil and mannitol. The invention further discloses a preparation method of the PVC compound stabilizer. The PVC compound stabilizer has the advantages of being free of toxin, environmentally friendly, good in lubricity and the like, is high in thermal stability, high in transparency, high in impact resistance and high in profile welded corner strength, can reduce damage to PVC molecules caused by ultraviolet light, improve outdoor aging performance of a product and further has good internal and external lubricating properties, and processing can be conducted stably.

Description

technical field [0001] The invention relates to a PVC composite stabilizer and a preparation method thereof, belonging to the technical field of composite material preparation. Background technique [0002] Polyvinyl chloride (PVC) is one of the most widely used synthetic resins in the world, and its products are widely used in various fields of production and life because of their many excellent properties. However, PVC is a high molecular polymer containing many chlorine atoms in the molecular chain. Due to the obvious inhomogeneity of the electron cloud distribution in the chlorine atom and the entire molecular chain, the molecular chain has serious defects. This leads to the removal of HCl from PVC above 110°C, and thermal degradation reaction occurs. Since only above 140°C, PVC has fluidity. Therefore, in order to ensure the smooth processing of PVC, a heat stabilizer must be added. At present, the commonly used lead salts and organotin heat stabilizers all have certai...
