Abstract

The invention discloses a flame-retardant polypropylene anti-aging masterbatch, which comprises the following components and the weight percentage of each component is: light stabilizer 5-9%, antioxidant 2,6-di-tert-butyl-4-methylphenol 12 ~16%, polypropylene 55~65%, polybutene 10~15%, decabromodiphenylethane 5~10%. The invention has the advantages of good flame retardant and anti-aging effects, stable performance, natural degradation after use, and no environmental pollution, and can be widely used in agricultural harvest cloth, cover cloth, beach tent, car cover, seat sets and other fields.

Description

technical field [0001] The invention relates to a flame-retardant polypropylene anti-aging masterbatch. Background technique [0002] Polymer materials may deteriorate at all stages of their synthesis, storage, processing and final use, that is, the performance of the material is reduced, such as yellowing, cracking on the surface of the product, loss of gloss, and reduction in impact strength, etc. The fiber shows a decrease in mechanical properties such as tensile strength and elongation at break, thus affecting the normal use of the product. This phenomenon is the aging of the polymer. [0003] Due to the special molecular structure of polypropylene material, the aging phenomenon is particularly serious. During the production, storage, processing and use of polypropylene products, the most exposed environment is heat and light. The main causes of polypropylene aging are thermal degradation and photodegradation. During the processing of polypropylene, due to mechanical s...
