Abstract
The invention discloses an anti-yellowing flame-retardant weather-resistant polypropylene composition and a preparation method thereof. The anti-yellowing flame-retardant weather-resistant polypropylene composition consists of the following components in percentage by weight: 58.5-82.7 percent of polypropylene, 3-8 percent of halogen-series flame retardant, 1.5-4 percent of flame-retardant synergist, 10-20 percent of mineral intensifier, 2-5 percent of light screener, 0.1-1 percent of light absorbing agent, 0.1-1 percent of hindered anime light stabilizer, 0.1-0.5 percent of main antioxidant, 0.1-0.5 percent of auxiliary antioxidant, 0.3-1 percent of processing aid and 0.1-0.5 percent of coloring agent. The flame retardant rating of the polypropylene composition provided by the invention is up to UL94V-2, high mechanical performance can be kept under long-term outdoor or ultraviolet ray irradiation, the yellowing degree is low, and the weather resistance of the material is greatly improved. The anti-yellowing flame-retardant weather-resistant polypropylene composition is mainly applied to home appliance components, large-sized outdoor stadium plastic seats, automobile parts and the like which are influenced by ultraviolet rays.
Description
technical field [0001] The invention discloses an anti-yellowing, flame-retardant and weather-resistant modified polypropylene composition, which is mainly used for household appliance parts affected by ultraviolet light, plastic seats for large outdoor stadiums, auto parts and the like. Background technique [0002] In recent years, the sales volume of flame-retardant polypropylene has been increasing day by day, and new application fields have been increasing, but the light stabilization of flame-retardant polypropylene is still a technical problem. Because most flame-retardant polypropylene currently uses brominated flame retardants, the acidic substances produced during processing and storage (especially under sunlight) seriously deteriorate the performance of hindered amine (HALS) light stabilizers. Based on the mechanism of acidic compounds generated by the decomposition of aliphatic and aromatic brominated flame retardants. The light stabilization of flame-retardant ...
