Chinese patent application 200710027370.4 discloses a high-efficiency heat-resistant composite light stabilizer for polyolefins, including: a mixed component of two or more polymeric hindered amine light stabilizers, a metal ion chelating component, and the metal ion The chelating component has at least a bisamide metal ion chelating structure; by introducing a high-efficiency heat-resistant oxygen aging component with a bisamide metal ion chelating structure and a certain light-resistant oxygen aging effect, it can eliminate the impact of metal ions on macromolecular materials. Catalytic breaking effect of the chain, but it is easy to be extracted by the medium during the processing, resulting in a large loss, and the composite light stabilizer is easily affected by pesticides and other substances, resulting in poor performance
That is, if the stabilizer is properly compounded, the synergistic effect can be produced between the stabilizers; on the contrary, the stabilizer not only fails to stabilize, but may cause the light resistance of the polymer to deteriorate or accelerate aging

Abstract

The invention provides a light stabilizer composition and belongs to the technical field of plastic processing. The light stabilizer composition comprises, by mass parts, 30-50 parts of hindered amine light stabilizer, 5-15 parts of distearyl pentaerythritol diphosphite and 0.5-5 parts of dibutyl adipate. The light stabilizer composition remarkably improves light stability, is good in compatibility, does not degrade easily in the processing and using process and is good in light resistance, ageing resistance and pesticide resistance, and the phenomenon of greenhouse burst caused due to the fact that a made greenhouse film is subjected to in influences of acidic materials such as pesticides in the greenhouse film application process can be avoided.

Description

technical field [0001] The invention belongs to the technical field of plastic processing, and in particular relates to a light stabilizer composition and a preparation method thereof. Background technique [0002] Polyvinyl chloride (PVC) is a typical amorphous polymer with good transparency and high film surface energy. It is suitable for the preparation of plastic packaging films and is conducive to secondary processing such as printing and bonding. PVC film has good transparency, stable performance, easy printing, and low price. It is mainly used in construction, decoration, packaging, agriculture and other industries, and has a wide range of uses. [0003] Polymer materials such as plastics exposed to sunlight or ultraviolet light for a long time will deteriorate in appearance and physical properties such as fading, surface cracking, and deterioration of tensile strength. This phenomenon is called photoaging. In order to make polymer materials have light-stabilizing pr...
